Municipal Cash Series Prime Cash Series IMPORTANT INFORMATION FOR SHAREHOLDERS Municipal Cash Series and Prime Cash Series will hold a special meeting of shareholders on May 15, 1998. It is important for you to vote on the issues described in this Proxy Statement. We recommend that you read the Proxy Statement in its entirety; the explanations it includes will help you decide upon the issues. TIME IS OF THE ESSENCE. . .YOUR PARTICIPATION IN THIS PROCESS IS IMPORTANT! BE SURE TO COMPLETE AND RETURN YOUR PROXY CARD PROMPTLY TO AVOID ADDITIONAL EXPENSE TO THE FUNDS. The following is an introduction to the proposals and the process. Why am I being asked to vote? Mutual funds are required to obtain shareholders' votes for certain types of changes, like those included in this Proxy Statement. You have a right to vote on these changes. What issues am I being asked to vote on? The proposals include the election of Directors and changes to the Funds' fundamental investment policies. Why are these individuals recommended for election to the Board of Directors? The Funds are devoted to serving the needs of their shareholders, and the Board is responsible for managing the Funds' business affairs to meet those needs. The Board represents the shareholders and can exercise all of the Funds' powers, except those reserved only for shareholders. Directors are selected on the basis of their education and professional experience. Candidates are chosen based on their distinct interest in, and capacity for understanding the complexities of, the operation of a mutual fund. These individuals bring considerable experience to the impartial oversight of a fund's operation. The Proxy Statement includes a brief description of each nominee's background and current position with the Funds. Why are the Funds' "fundamental policies" being changed or removed? Every mutual fund has certain investment policies that can be changed only with the approval of its shareholders. These are referred to as "fundamental" investment policies. In the past, these policies were adopted to reflect regulatory, business, or industry conditions that no longer exist or no longer are necessary. By reducing the number of "fundamental policies," the Funds may be able to minimize the costs and delays associated with frequent shareholder meetings. Also, the investment adviser's ability to manage the Funds' assets may be enhanced and investment opportunities increased. The proposed amendments will: i. simplify and modernize the policies that are required to be "fundamental" by the Investment Company Act of 1940; ii. reclassify certain fundamental policies not required to be fundamental by the 1940 Act as operating policies; and iii. remove fundamental policies that are no longer required by the securities laws of individual states. Federated is a conservative money manager. Our highly trained professionals are dedicated to making investment decisions in the best interest of the Funds and their shareholders. Why are some "fundamental policies" being reclassified as "operating" policies? As noted above, some "fundamental policies" have been redefined as "operating policies." Operating policies do not require shareholder approval to be changed. This permits the Funds' Board additional flexibility in determining whether to participate in new investment opportunities and to meet industry changes promptly. How do I vote my shares? You may vote in person at the special meeting of shareholders or simply sign and return the enclosed Proxy Card. If we do not receive your proxy card, Shareholder Communications Corporation, our proxy solicitor, may contact you to request that you cast your vote. Who do I call if I have questions about the Proxy Statement? Call your Fund Representative or a Federated Client Service Representative. Federated's toll-free number is 1-800-341-7400. After careful consideration, the Board of Directors has unanimously approved these proposals. The Board recommends that you read the enclosed materials carefully and vote FOR all proposals.

Municipal Cash Series Prime Cash Series Federated Investors Funds 5800 Corporate Drive Pittsburgh, PA 15237-7000 About the Proxy Solicitation and the Special Meeting The enclosed proxy is solicited on behalf of the Board of Directors of the Company (the "Board" or "Directors"). The proxies will be voted at the special meeting of shareholders of the Company to be held on May 15, 1998, at Federated Investors Tower, 19th Floor, 1001 Liberty Avenue, Pittsburgh, Pennsylvania 15222-3779, at 2:00 p.m. (such special meeting and any adjournment or postponement thereof are referred to as the "Special Meeting"). The cost of the solicitation, including the printing and mailing of proxy materials, will be borne by the Funds. In addition to solicitations through the mails, proxies may be solicited by officers, employees, and agents of the Funds or, if necessary, a communications firm retained for this purpose. Such solicitations may be by telephone, telegraph, or otherwise. Any telephonic solicitations will follow procedures designed to ensure accuracy and prevent fraud, including requiring identifying shareholder information, recording the shareholder's instructions, and confirming to the shareholder after the fact. Shareholders who communicate proxies by telephone or by other electronic means have the same power and authority to issue, revoke, or otherwise change their voting instruction as currently exists for instructions communicated in written form. The Funds will reimburse custodians, nominees, and fiduciaries for the reasonable costs incurred by them in connection with forwarding solicitation materials to the beneficial owners of shares held of record by such persons. At its meeting on November 20, 1997, the Board reviewed the investment policies of the Funds and approved changes to them, subject to shareholder approval. The purposes of the Special Meeting are set forth in the accompanying Notice. The Directors know of no business other than that mentioned in the Notice that will be presented for consideration at the Special Meeting. Should other business properly be brought before the Special Meeting, proxies will be voted in accordance with the best judgment of the persons named as proxies. This proxy statement and the enclosed proxy card are expected to be mailed on or about March 16, 1998, to shareholders of record at the close of business on February 26, 1998 (the "Record Date"). On the Record Date, Municipal Cash Series had outstanding 618,768,623 shares of common stock and Prime Cash Series had outstanding 3,520,377,078 shares of common stock. The Funds' annual reports, which include audited financial statements for each Fund for the fiscal year ended May 31, 1997, were previously mailed to shareholders. Requests for a semi-annual report for each Fund, which contains unaudited financial statements for the period ended November 30, 1997, may be made in writing to the Company's principal executive offices at Federated Investors Funds, 5800 Corporate Drive, Pittsburgh, Pennsylvania 15237-7000 or by calling toll-free 1-800-341-7400. ELECTION OF THREE DIRECTORS The persons named as proxies intend to vote in favor of the election of Thomas G. Bigley, John E. Murray, Jr., and Nicholas P. Constantakis as Directors of the Company. All of the nominees are presently serving as Directors. Please see "Information about the Company" for current biographical information about Messrs. Bigley, Murray, and Constantakis. Messrs. Bigley and Murray were appointed Directors on November 15, 1994 and February 14, 1995, respectively, to fill vacancies resulting from the decision to expand the size of the Board. Mr. Constantakis was appointed a Director on February 23, 1998, to fill the vacancy created by the death of Mr. Gregor Meyer on November 2, 1997. All Nominees have consented to continue to serve if elected. If elected, the Directors will hold office without limit in time until death, resignation, retirement, or removal or until the next meeting of shareholders to elect Directors and the election and qualification of their successors. If any nominee for election as a Director named above shall by reason of death or for any other reason become unavailable as a candidate at the Special Meeting, votes pursuant to the enclosed proxy will be cast for a substitute candidate by the proxies named on the proxy card, or their substitutes, present and acting at the Special Meeting. Any such substitute candidate for election as an interested Director shall be nominated by the Executive Committee. The selection of any substitute candidate for election as a Director who is not an interested person shall be made by a majority of the Directors who are not interested persons of the Company. The Board has no reason to believe that any nominee will become unavailable for election as a Director. APPROVAL OR DISAPPROVAL OF CHANGES TO THE FUNDS' FUNDAMENTAL INVESTMENT POLICIES The Investment Company Act of 1940 (the 1940 Act") requires investment companies such as the Company to adopt certain specific investment policies that can be changed only by shareholder vote. An investment company may also elect to designate other policies that may be changed only by shareholder vote. Both types of policies are often referred to as "fundamental policies." Certain of the Funds' fundamental policies have been adopted in the past to reflect regulatory, business or industry conditions that are no longer in effect. Accordingly, the Directors have approved, and have authorized the submission to the Funds' shareholders for their approval, the removal or amendment of certain of the Funds' fundamental policies. The proposed amendments would: (i) simplify and modernize the policies that are required to be fundamental by the 1940 Act; (ii) reclassify as operating policies those fundamental policies that are not required to be fundamental by the 1940 Act; and (iii)remove those fundamental policies which are no longer required by the securities laws of individual states as a result of the National Securities Markets Improvement Act ("NSMIA"), dated October 11, 1996. By reducing to a minimum those policies that can be changed only by shareholder vote, the Directors believe that the Company would be able to minimize the costs and delay associated with holding frequent shareholder meetings. The Directors also believe that the investment adviser's ability to manage the Funds' assets in a changing investment environment will be enhanced and that investment management opportunities will be increased by these changes. As a general matter, if these proposals are not approved, the policies will continue as currently stated. The Board of Directors will consider what future action should be taken. TO AMEND EACH FUNDS' FUNDAMENTAL INVESTMENT POLICY ON DIVERSIFICATION OF ITS INVESTMENTS Each Funds' current fundamental investment policy on diversification of its investments is as follows: Municipal Cash Series: "With respect to securities comprising 75% of its assets, the Fund will not invest more than 10% of its total assets in the securities of any one issuer. Under this limitation, each governmental subdivision, including states and the District of Columbia, territories, possessions of the United States, or their political subdivisions, agencies, authorities, instrumentalities, or similar entities, will be considered a separate issuer if its assets and revenues are separate from those of the governmental body creating it and the security is backed only by its own assets and revenues. Industrial development bonds backed only by the assets and revenues of a non-governmental user, are considered to be issued solely by that user. If in the case of an industrial development bond or government-issued security, a governmental or some other entity guarantees the security, such guarantee would be considered a separate security issued by the guarantor as well as the other issuer, subject to limited exclusions allowed by the Investment Company Act of 1940." Prime Cash Series: "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, or securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by U.S. government securities) if as a result more than 5% of the value of its total assets would be invested in the securities of that issuer, or if it would own more than 10% of the outstanding voting securities of that issuer." In 1996, the SEC amended Rule 2a-7, under the 1940 Act, which governs the operations of money market funds. The amendments established specific diversification requirements for money market funds which are more restrictive than, and supersede, the Funds' current policies. Since the Funds are money market funds which rely on amortized cost valuation of their portfolio securities to attempt to maintain a $1.00 net asset value, they have complied with the Rule 2a-7 diversification requirements since their adoption and intend to continue to comply with them. Therefore, the Directors propose to remove the Funds' current diversification policies because they are obsolete in light of the requirements of Rule 2a-7 and follow the investment policy that the Funds will comply with Rule 2a-7. THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE PROPOSAL TO AMEND THE PRIME CASH SERIES FUNDAMENTAL INVESTMENT POLICY ON ITS INTENTION TO CONCENTRATE PORTFOLIO INVESTMENTS IN ONE INDUSTRY This proposal is to considered only by shareholders of Prime Cash Series. The 1940 Act requires every investment company to state a fundamental policy on its intention to concentrate portfolio investments in one industry. Investments of 25% or more of the value of a fund's assets in any one industry represent a "concentration" in that particular industry. However, if a fund does not intend to concentrate its investments, this must also be stated. Prime Cash Series' current concentration policy requires it to invest 25% or more of its total assets in commercial paper issued by finance companies. Since the Fund adopted its policy to concentrate investments in commercial paper issued by finance companies, the investment focus of the Fund's investment adviser and the security types in which it would like to invest the Fund's assets have changed. Therefore, the Fund's investment adviser has recommended to the Board of Directors that the concentration policy be amended to eliminate the requirement to concentrate in the commercial paper issued by finance companies. By eliminating the requirement, the investment adviser believes that the risk to the Fund's portfolio would be reduced and that the investment adviser would have greater flexibility to invest in a broader variety of the securities which are acceptable investments for the Fund in pursuing its investment objective to achieve current income consistent with stability of principal and liquidity. Therefore, the Directors recommend that the Fund's fundamental investment policy on concentration be amended as follows: "The Fund will not invest 25% or more of its total assets in any one industry. However, investing in U.S. government securities and domestic bank instruments shall not be considered investments in any one industry." THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE PROPOSAL TO AMEND AND TO CHANGE FROM A FUNDAMENTAL TO AN OPERATING POLICY EACH FUNDS' ABILITY TO INVEST IN RESTRICTED SECURITIES Each Funds' current policy on restricted securities reads as follows: Municipal Cash Series: "The Fund will not invest more than 10% of its net assets in securities subject to restrictions on resale under the Securities Act of 1933." Prime Cash Series: "The Fund will not invest more than 10% of its net assets in securities subject to restrictions on resale under the federal securities laws except for Section 4(2) commercial paper." This policy was adopted because historically, restricted securities were viewed as illiquid since they could not be sold within seven days. Investment companies, such as the Company, are required to meet a shareholder's redemption request at the current net asset value within seven days of receiving the request for redemption. In order to do this, some portion of the securities in each Funds' portfolio must be "liquid" so that the securities can be sold in sufficient time to obtain the necessary cash to meet redemption requests. It is important to note that many restricted securities are, in fact, quite liquid, and can be purchased without jeopardizing the liquidity of each Funds' portfolio. Certain state securities regulators previously required mutual funds to have a fundamental policy limiting investment in restricted securities. Since the enactment of NSMIA, states no longer have such jurisdiction. Furthermore, rules adopted by the Securities and Exchange Commission have substantially increased the number of restricted securities that can now be considered liquid and, in addition, have given to the Directors the ability to determine, under specific guidelines, that a security is liquid. The Directors may delegate this duty to the investment adviser provided the Adviser's determination of liquidity is made in accordance with the guidelines established and monitored by the Directors. The Funds' current policy prevents the Funds' from acquiring a significant amount of restricted securities, other than Section 4(2) commercial paper, even though they are viewed by the adviser to be liquid. If this proposal is approved, the Funds' will be able to invest to an unlimited extent in restricted securities as long as they meet the Directors' guidelines for liquidity and the Funds' operating policy on restricted securities would read substantially as follows: "The Fund may invest in restricted securities. Restricted securities are any securities in which the Fund may invest pursuant to its investment objective and policies but which are subject to restrictions on resale under federal securities law. Under criteria established by the Directors certain restricted securities are determined to be liquid. To the extent that restricted securities are not determined to be liquid the Fund will limit their purchase, together with other illiquid securities, to 10% of its net assets." If a restricted security is determined not to be liquid, the purchase of that security, together with other illiquid securities, may not exceed 10% of each Fund's net assets in accordance with each Fund's current policy on investing in illiquid securities. If shareholders do not approve the above proposal, the Funds will continue to invest no more than 10% of the value of its total assets in restricted securities of any kind, except Section 4(2) commercial paper. THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE PROPOSAL INFORMATION ABOUT THE COMPANY Quorum and Voting Requirements The favorable vote of: (a) the holders of 67% or more of the outstanding voting securities present at the meeting, if the holders of 50% or more of the outstanding voting securities of the Funds' are present or represented by proxy; or (b) the vote of the holders of more than 50% of the outstanding voting securities, whichever is less, is required to approve all of the proposals except for the election of Directors. Election of a Director requires the affirmative vote of a plurality of the votes cast at the Special Meeting. A "plurality" is defined as more votes cast for than against each Nominee. Only shareholders of record on the Record Date will be entitled to vote at the Special Meeting. Each share of each Fund is entitled to one vote. Fractional shares are entitled to proportionate shares of one vote. Any person giving a proxy has the power to revoke it any time prior to its exercise by executing a superseding proxy or by submitting a written notice of revocation to the Secretary of the Company. In addition, although mere attendance at the Special Meeting will not revoke a proxy, a shareholder present at the Special Meeting may withdraw his or her proxy and vote in person. All properly executed and unrevoked proxies received in time for the Special Meeting will be voted in accordance with the instructions contained in the proxies. If no instruction is given on the proxy, the persons named as proxies will vote the shares represented thereby in favor of the matters set forth in the attached Notice. In order to hold the Special Meeting, a "quorum" of shareholders must be present. Holders of one-third of the total number of outstanding shares of each Fund of the Company, present in person or by proxy, shall be required to constitute a quorum for the purpose of voting on the proposals made. For purposes of determining a quorum for transacting business at the Special Meeting, abstentions and broker "non-votes" (that is, proxies from brokers or nominees indicating that such persons have not received instructions from the beneficial owner or other persons entitled to vote shares on a particular matter with respect to which the brokers or nominees do not have discretionary power) will be treated as shares that are present but which have not been voted. For this reason, abstentions and broker non-votes will have the effect of a "no" vote for purposes of obtaining the requisite approval of the proposals. If a quorum is not present, the Special Meeting may be adjourned to a later date by the affirmative vote of a majority of the shares present or represented by proxy. In the event that a quorum is present but sufficient votes in favor of one or more of the proposals have not been received, the persons named as proxies may propose one or more adjournments of the Special Meeting to permit further solicitations of proxies with respect to such proposal(s). Any adjournments for this purpose will require the affirmative vote of a majority of the shares cast in person or by proxy at the session of the Special Meeting to be adjourned. The persons named as proxies will vote those proxies which they are entitled to vote FOR the proposal in favor of such an adjournment and will vote those proxies required to be voted AGAINST the proposal against any adjournment. A shareholder vote may be taken on the proposals in this proxy statement prior to any such adjournment if sufficient votes have been received for approval.
