TIME IS OF THE ESSENCE . . . VOTING ONLY TAKES A FEW MINUTES AND YOUR PARTICIPATION IS IMPORTANT! ACT NOW TO HELP AVOID ADDITIONAL EXPENSE. Federated Technology Fund ("Technology Fund), a portfolio of Federated Equity Funds, will hold a special meeting of shareholders on February 29, 2008. IT IS IMPORTANT FOR YOU TO VOTE. We recommend that you read the Prospectus/Proxy Statement in its entirety. WHY AM I BEING ASKED TO VOTE? Mutual funds are required to obtain shareholders' votes for certain types of changes, like the one included in this Prospectus/Proxy Statement. You have a right to vote on these changes. WHAT AM I BEING ASKED TO VOTE ON? To approve or disapprove a proposed Agreement and Plan of Reorganization pursuant to which Federated MDT Small Cap Growth Fund ("MDT Fund"), a portfolio of Federated MDT Series, would acquire all of the assets of Technology Fund in exchange for Class A Shares, Class B Shares and Class C Shares of MDT Fund to be distributed pro rata by Technology Fund in complete liquidation and termination of Technology Fund (such proposal hereafter referred to as the "Reorganization" or "Proposed Reorganization"). WHY IS THE REORGANIZATION BEING PROPOSED? The Board of Trustees (the "Board") of Federated Equity Funds has determined that a reorganization of Technology Fund into MDT Fund is in the best interest of the Technology Fund and its shareholders and is recommending that shareholders of Technology Fund approve the Reorganization. The Reorganization is being proposed to shareholders of Technology Fund primarily because, in the opinion of the Technology Adviser, the long continuing net redemption activity in Technology Fund's shares (which has caused its net assets to decrease to $66.6 million at October 8, 2007 from $546.5 million at December 31, 2000) raises questions as to Technology Fund's long-term viability. Technology Fund was initially launched as the Federated Communications Technology Fund ("FCTF") in September 1999, with the strategy of investing in shares of issuers engaged in the information technology and telecommunication services businesses. FCTF initially experienced large inflows of investor subscriptions, as well as a high rate of capital appreciation of its portfolio holdings, and by March 2000 its net assets exceeded $1 billion. With the bursting of the "tech bubble" in March 2000, however, FCTF's performance and assets began a sustained downward trend. In order to reposition FCTF for further growth, on December 31, 2003 the Fund was renamed and its strategy was broadened so that it could focus on the entire technology sector (rather than just communications technology), but the revised strategy has not succeeded in attracting additional investments into Technology Fund. Technology Adviser believes that Technology Fund shareholders would benefit from becoming shareholders of MDT Fund, whose net assets have, since its inception in 2005, steadily increased to $26.6 million at October 8, 2007. Like Technology Fund, MDT Fund seeks to achieve capital appreciation by investing primarily in securities that exhibit promising long-term potential ("growth stocks"), but, unlike Technology Fund, MDT Fund is permitted to invest its assets in a full range of industry sectors (including a substantial portion in technology stocks), thereby providing shareholders with greater industry sector diversification within the growth stock sphere. WHAT ARE SOME OF THE FACTORS THAT THE BOARD CONSIDERED IN RECOMMENDING THE PROPOSED REORGANIZATION? The Board considered various factors in reviewing this proposal including the following factors: {circle}the compatibility of Technology Fund's and MDT Fund's investment objectives, policies and limitations; {circle}the greater long-term viability of MDT Fund based on its asset growth trend versus Technology Fund's declining asset trend; {circle}that the Reorganization will not result in recognition of any gain or loss for federal income tax purposes either to Technology Fund or MDT Fund or to shareholders of Technology Fund; {circle}that Technology Fund's capital loss carry forward for federal income tax purposes will remain available to MDT Fund following the Reorganization subject to any applicable limitations under the Internal Revenue Code; {circle}that Technology Fund will incur brokerage costs as a result of its plan to sell and repurchase certain of its portfolio securities prior to the Reorganization in order to more fully utilize its capital loss carry-forward and that MDT Fund will also incur brokerage costs as a result of its Plan to sell, immediately following the Reorganization, all Technology Fund's securities acquired by MDT Fund in the Reorganization, and to purchase different securities with the proceeds of such sales; and {circle}that the per share expenses after waivers of MDT Fund following the Reorganization are projected to be less than those of Technology Fund prior to the Reorganization. HOW DO I VOTE MY SHARES? You may vote by telephone at the toll-free number shown on your ballot, in person at the meeting, or by completing and returning the enclosed proxy card. If you: 1. Choose to help save time and postage costs by voting by telephone; please do not return your proxy card. 2.

MDT Fund shares will be distributed pro rata by Technology Fund to its shareholders in complete liquidation and dissolution of Technology Fund. As a result of the Reorganization, each owner of Technology Fund's Class A Shares, Class B Shares and Class C Shares will become the owner of Class A Shares, Class B Shares and Class C Shares of MDT Fund, having a total net asset value ("NAV") equal to the total NAV of his or her holdings in Technology Fund on the date of the Reorganization (the "Closing Date"). The Board of Trustees (the "Board") of the Trust has determined that a reorganization of Technology Fund into MDT Fund is in the best interest of Technology Fund and its shareholders and is recommending that shareholders of Technology Fund approve the Reorganization. Technology Fund's investment objective is to achieve capital appreciation. Similarly, MDT Fund's investment objective is to seek long-term capital appreciation. Technology Fund and MDT Fund each uses the "growth" style of investing, seeking to select those securities within its investment universe that exhibit the most promising long-term growth potential. Technology Fund pursues its investment objective by investing primarily in companies that rely extensively on technology in their products, services or operations while MDT Fund pursues its investment objective by investing primarily in common stock of small U.S. companies. For a comparison of the investment policies and objectives of Technology Fund and MDT Fund (each a "Fund" and collectively the "Funds"), see "Summary -- Comparison of Investment Objectives, Policies and Limitations." Information concerning MDT Fund shares, as compared to the shares of Technology Fund, is included in this Prospectus/Proxy Statement in the sections entitled "Summary -- Comparative Fee Tables" and "Information about the Reorganization - Description of MDT Fund Shares and Capitalization."

A copy of the Agreement and Plan of Reorganization (the "Plan") pursuant to which the Reorganization will be conducted is attached to this Prospectus/Proxy Statement as Exhibit A and a copy of Technology Fund's Management's Discussion of Fund Performance is attached to this Prospectus/Proxy Statement as Exhibit B. The Prospectus for MDT Fund's Class A Shares and Class C Shares or the Prospectus for MDT Fund's Class B Shares, as the case may be, accompanies this Prospectus/Proxy Statement. REASONS FOR THE PROPOSED REORGANIZATION The Reorganization is being proposed to shareholders of Technology Fund primarily because, in the opinion of the Technology Adviser, the long continuing net redemption activity in Technology Fund's shares (which has caused its net assets to decrease to $66.6 million at October 8, 2007 from $546.5 million at December 31, 2000) raises questions as to Technology Fund's long-term viability. Technology Fund was initially launched as the Federated Communications Technology Fund ("FCTF") in September 1999, with the strategy of investing in shares of issuers engaged in the information technology and telecommunication services businesses. FCTF initially experienced large inflows of investor subscriptions, as well as a high rate of capital appreciation of its portfolio holdings, and by March 2000 its net assets exceeded $1 billion. With the bursting of the "tech bubble" in March 2000, however, FCTF's performance and assets began a sustained downward trend. In order to reposition FCTF for further growth, on December 31, 2003 the Fund was renamed and its strategy was broadened so that it could focus on the entire technology sector (rather than just communications technology), but the revised strategy has not succeeded in attracting additional investments into Technology Fund. Technology Adviser believes that Technology Fund shareholders would benefit from becoming shareholders of MDT Fund, whose net assets have, since its inception in 2005, steadily increased to $26.6 million at October 8, 2007. Like Technology Fund, MDT Fund seeks to achieve capital appreciation by investing primarily in securities that exhibit promising long-term potential ("growth stocks"), but, unlike Technology Fund, MDT Fund is permitted to invest its assets in a full range of industry sectors (including a substantial portion in technology stocks), thereby providing shareholders with greater industry sector diversification within the growth stock sphere. Holders of Class A Shares and Class C Shares of Technology Fund will receive in the Reorganization an equivalent net asset value of Class A Shares or Class C shares of MDT Fund, both existing classes. In the Reorganization, holders of Class B shares of Technology Fund will receive an equivalent net asset value of Class B Shares of MDT Fund, which is a new share class of MDT Fund created for the Reorganization. The Board has voted to recommend to holders of shares of Technology Fund the approval of the Plan, pursuant to which MDT Fund would acquire all of the assets of Technology Fund in exchange for Class A Shares, Class B Shares and Class C Shares of MDT Fund (the "Exchange"). Immediately following the Exchange, Technology Fund will distribute the Class A Shares, Class B Shares and Class C Shares of MDT Fund received in the Exchange pro rata to holders of its Class A Shares, Class B Shares and Class C Shares, respectively, in a complete liquidation and termination of Technology Fund. As a result of the Reorganization, each holder of Class A Shares, Class B Shares and Class C Shares of Technology Fund will become the owner of Class A Shares, Class B Shares and Class C Shares of MDT Fund, respectively, in each case having a total net asset value equal to the total net asset value of his or her holdings in Technology Fund on the date of the Reorganization. Following the consummation of the Reorganization, the Trust will amend its Declaration of Trust to remove Technology Fund as a series of the Trust. In considering the proposed Reorganization, the Board took into consideration a number of factors, including: (1) the compatibility of Technology Fund's and MDT Fund's investment objectives, policies and limitations; (2) the greater long-term viability of MDT Fund based on its asset growth trend versus Technology Fund's declining asset trend; (3) that the Reorganization will not result in recognition of any gain or loss for federal income tax purposes either to Technology Fund or MDT Fund or to shareholders of Technology Fund; (4) that Technology Fund's capital loss carry forwards for federal income tax purposes will remain available to MDT Fund following the Reorganization subject to any applicable limitations under the Internal Revenue Code; (5) that the per share expenses after waivers of MDT Fund immediately following the Reorganization are projected to be less than those of Technology Fund prior to the Reorganization (although there can be no assurance that MDT Fund's expense waivers will continue at their current levels for future periods); and (6) that Technology Fund will incur brokerage costs as a result of its plan to sell certain of its portfolio securities (and possibly purchase replacement securities) prior to the Reorganization in order to more fully utilize capital gains against its capital loss carry-forwards and that MDT Fund will also incur brokerage costs as a result of its Plan to sell, immediately following the Reorganization, substantially all Technology Fund's securities acquired by MDT Fund in the Reorganization, and to purchase different securities with the proceeds of such sales. The Board concluded to recommend to shareholders of Technology Fund that they vote to approve the Reorganization. Pursuant to Rule 17a-8 under the Investment Company Act of 1940 (the "1940 Act"), the Board, including a majority of the Trustees who are not "interested persons" within the meaning of Section 2(a)(19) of the 1940 Act, determined that the Reorganization is in the best interest of Technology Fund and its shareholders, and that the interests of existing Technology shareholders would not be diluted as a result of the Reorganization. The Board of Trustees (the "Trustees") of MDT Fund likewise approved the Reorganization on behalf of MDT Fund. Pursuant to Rule 17a-8 under the 1940 Act, the Trustees of MDT Fund, including a majority of the Trustees who are not "interested persons," determined that the Reorganization is in the best interest of MDT Fund and its shareholders, and that the interests of existing MDT Fund shareholders would not be diluted as a result of the Reorganization. TAX CONSEQUENCES As a condition of the Reorganization, each Fund will receive an opinion of counsel that the Reorganization will be considered a tax-free "reorganization" under applicable provision of the Internal Revenue Code of 1986, as amended, so that no gain or loss will be recognized upon the Reorganization by either Fund or by Technology Fund shareholders. The tax basis of MDT Fund's Class A Shares, Class B Shares and Class C Shares received by Technology Fund's shareholders will be the same as the tax basis of their shares in Technology Fund. Because Technology Fund has a capital loss carry-forward greatly in excess of its unrealized capital gains, there will be no capital gains distributions by Technology Fund before the Closing Date, even if gains are realized on dispositions of portfolio securities in connection with the Reorganization. Technology Fund will distribute to shareholders any previously undistributed ordinary income accumulated prior to the Reorganization. THE BOARD OF TRUSTEES OF TECHNOLOGY FUND UNANIMOUSLY RECOMMENDS THAT YOU VOTE "FOR" APPROVAL OF THE REORGANIZATION. COMPARISON OF INVESTMENT OBJECTIVES, POLICIES AND LIMITATIONS The investment objectives of the two Funds are, for practical purposes, identical. The investment objective of MDT Fund is long-term capital appreciation, while the investment objective of Technology Fund is to achieve capital appreciation. Both Funds invest substantially all their net assets in common stocks. Both Funds use the "growth" style of investing, seeking to select securities that exhibit the most promising long-term growth potential. MDT Fund seeks to achieve its objective by investing primarily in common stock of small U.S. companies, i.e., those with a market capitalization range similar to those companies included in the Russell 2000 Growth Index ($133 million to $3.5 billion as of July 31, 2007). MDT Fund may not change its investment policy to normally invest at least 80% of its net assets in small capitalization issuers without 60 days advance notice to shareholders. MDT Fund seeks to control risk by limiting the extent to which the MDT Fund's exposure to any one business, industry or sector varies from that of the Russell 2000 Growth Index. Technology Fund seeks to achieve its objective by investing primarily in securities of companies considered by Technology Adviser, at the time of the investment, to rely extensively on technology in their products, services or operations. Technology Fund may not change its investment policy to normally invest at least 80% of its net assets in technology investments without 60 days advance notice to shareholders. In general, issuers selected by Technology Adviser will have a market capitalization of $100 million, but there is no minimum or maximum capitalization constraint on the size of the issuers selected. Technology Adviser attempts to diversify investments by allocating among companies in different technology related industries and by limiting the amount invested in any one issuer. While both Funds invest primarily in common stocks using the growth style of investing, the Funds differ in their stock selection processes. MDT Fund selects stocks for inclusion in its portfolio by using a proprietary quantitative model known as the Optimum Q Process. This model begins by screening its universe of stocks for those that meet certain valuation (e.g., price-to-earnings ratio, price-to-tangible-book-value ratio) and performance (e.g., earnings momentum or earnings growth) metrics that MDT Adviser believes might be indicative of an attractive investment opportunity. The selection process factors in trading costs (particularly market impact) by biasing MDT Fund towards those stocks which have less trading costs. The process also uses diversification constraints which keep the portfolio diversified by business, industry and sector. While Technology Adviser also uses quantitative metrics to screen stocks for Technology Fund's portfolio, its process is less quantitative and more judgment based. Technology Adviser attempts to identify those areas within the technology industries which present the best opportunities for growth. Technology Adviser performs traditional fundamental analysis to select securities that exhibit the most promising long-term growth potential for Technology Fund's portfolio. In selecting securities, Technology Adviser focuses primarily on the projected future cash flow and earnings of the issuing company, in addition to examining each issuer's current financial condition, business and product strength, competitive position, and management expertise. While each Fund will normally invest primarily in common stocks of U.S. issuers, each Fund may invest a portion of its assets in securities of companies outside the United States to diversify its holdings and to take advantage of opportunities in the foreign market. Securities of foreign companies may be more affected by foreign economic and political conditions, taxation policies, and accounting and auditing standards then those of U.S. companies. In addition, each Fund may use derivative contracts and/or hybrid instruments to implement elements of its investment strategy. For example, each Fund may use derivative contracts and/or hybrid instruments to increase or decrease the allocation of the portfolio to securities, currencies or types of securities in which each Fund may invest directly. Each Fund may also, for example, use derivative contracts to: {circle}obtain premiums from the sale of derivative contracts; {circle}realize gains from trading a derivative contract; or {circle}hedge against potential losses. There can be no assurance that either Fund's use of derivative contracts or hybrid instruments will work as intended. In addition to common stocks, derivative contracts and hybrid instruments, the Prospectus of MDT Fund also lists preferred stocks, foreign securities and securities of other investment companies, including exchange traded funds, as categories or securities in which MDT Fund may principally invest, while the Prospectus of Technology Fund lists foreign securities as principal investments. The Prospectus of MDT Fund also lists securities lending as a principal investment strategy. INVESTMENT LIMITATIONS Each Fund has fundamental investment limitations which may not be changed without shareholder approval. With three exceptions, the fundamental limitations of the two Funds are identical. The first difference between the fundamental imitations of the two funds concerns lending. Technology Fund's fundamental limitations prohibit it from making loans, while MDT Fund's fundamental limitations permit it to make loans in amounts up to one-third of its total assets. Neither Fund's lending limitation prohibits it from investing in debt obligations, entering into repurchase agreements or lending securities. MDT Fund may also make temporary loans to affiliated investment companies in accordance with the inter-fund borrowing and lending arrangements described in its SAI. The second difference relates to the permissibility of investing in commodities. Technology Fund's fundamental limitations prohibit it from investing directly in commodities, although it may purchase securities of companies that deal in commodities. For purposes of the commodities restriction, Technology Fund's non-fundamental investment limitation provides that investments in transactions involving futures contracts, options and other financial contracts that settle by payment of cash are not considered investments in commodities. MDT Fund's fundamental limitations permit MDT Fund to invest in commodities to the maximum extent permitted by the 1940 Act. The 1940 Act requires that a fund state in its registration statement a fundamental policy as to whether it reserves freedom of action to invest in commodities and prohibits a fund from purchasing commodities without shareholder approval except in accordance with that policy. The Act does not otherwise prohibit or restrict investments in commodities. MDT Fund has not in the past invested directly in commodities, and MDT Adviser has no present intention of doing so. The third difference relates to the Funds' respective concentration of investments policy, where MDT Fund is not permitted to "concentrate" (i.e., invest more than 25% of its total assets) in the securities of issuers primarily engaged in the same industry whereas Technology Fund is permitted to invest more than 25% of its total assets in the communications technology industry (but is not otherwise permitted to concentrate). The following chart compares the fundamental limitations of Technology Fund and MDT Fund. In addition, each Fund has non-fundamental limitations that prohibit it from investing more than 15% of its net assets in illiquid securities, purchasing securities on margin or mortgaging or pledging its assets except for collateral arrangements in connection with otherwise permissible activities. While shareholder approval is required to change a fundamental limitation, non-fundamental limitations may be changed by the Fund's Board. INVESTMENT LIMITATIONS TECHNOLOGY FUND MDT FUND DIVERSIFICATION OF INVESTMENTS (fundamental) DIVERSIFICATION With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities OF INVESTMENTS of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United (fundamental) States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government Same 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 the securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer. BORROWING MONEY AND ISSUING SENIOR SECURITIES (fundamental) BORROWING MONEY The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted AND ISSUING under the Investment Company Act of 1940 (1940 Act), any rule or order thereunder, or any SEC staff interpretation SENIOR thereof. SECURITIES (fundamental) Same INVESTING IN REAL ESTATE (fundamental) INVESTING IN The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from REAL ESTATE investing in issuers which invest, deal, or otherwise engage in transactions in real estate or interests therein, (fundamental) or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights Same 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. INVESTING IN COMMODITIES (fundamental) INVESTING IN The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of COMMODITIES companies that deal in commodities. For purposes of this restriction, investments in transactions involving futures (fundamental) contracts and options, forward currency contracts, swap transactions and other financial contracts that settle by The Fund may payment of cash are not deemed to be investments in commodities. invest in commodities to the maximum extent permitted under the 1940 Act. UNDERWRITING (fundamental) UNDERWRITING The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions (fundamental) involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be Same considered to be an underwriter under the Securities Act of 1933. CONCENTRATION (fundamental) CONCENTRATION The Fund will not invest more than 25% of its total assets (valued at the time of investment) in securities of (fundamental) companies engaged principally in any one industry other than the communications technology industry, except that The Fund will this restriction does not apply to cash or cash items and securities issued or guaranteed by the United States not make government or its agencies or instrumentalities. investments that will result in the concentration of its investment in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments will not be deemed to constitute an industry.

COMPARISON OF PRINCIPAL RISKS All mutual funds take investment risks. Therefore, it is possible to lose money by investing in either Fund. Since both Technology Fund and MDT Fund invest in common stocks and use the growth style of investing, an investment in MDT Fund presents many of the same types of investment risks as investing in Technology Fund. A principal risk factor applicable to an investment in either Fund is stock market risk. The value of equity securities in each Fund will rise and fall. Each Fund's portfolio will reflect changes in prices of individual portfolio stocks or general changes in stock valuations. Each Fund's share price may decline. Each Fund's Adviser attempts to manage market risk by limiting the amount the Fund invests in the securities of any individual company or of companies in any one sector or industry. However, diversification will not protect either Fund against widespread or prolonged declines in the stock market. Moreover, since Technology Fund must invest at least 80% of its net assets in technology related investments, Technology Fund may be deemed to be more limited in its ability to diversify its investments among industry categories than MDT Fund, which has the ability to invest in all industry categories. Each Fund is also exposed to risks related to investing for growth. Due to their relatively high valuations, growth stocks are typically more volatile than value stocks. Further, growth stocks may not pay dividends or may pay lower dividends than value stocks. This means they depend more on price changes for returns and may be more adversely affected in a down market compared to value stocks that pay higher dividends. Each Fund's investments in common stocks may include ADRs and domestically traded securities of foreign issuers. Such investments expose the Fund to a greater risk that its share price may be affected by foreign economic and political conditions, taxation policies and accounting and auditing standards than would otherwise be the case. Each Fund also lists non-domestically traded foreign securities as a category in which it may principally invest. In addition to the risks of foreign securities traded in United States markets, the combination of currency risk and market risk tend to make securities traded in foreign markets more volatile than those traded exclusively in the United States. Since MDT Fund must invest 80% of its assets in stocks of small capitalization companies, the risks related to company size are a significant risk in that Fund. Specifically, investment in smaller capitalization issuers exposes MDT Fund to a greater risk that its share price may be affected by the fact that the smaller the capitalization of a company, the fewer the number of shares traded daily, the less liquid its stock and the more volatile its price. In addition, smaller capitalization companies tend to have unproven track records, a limited product or service base and limited access to capital. On the other hand, since Technology Fund must invest 80% of its assets in technology companies, sector risk is a significant risk in that Fund. Specifically, such investments expose Technology Fund to the risk that as its Adviser allocates more of the Fund's portfolio to a particular sector (i.e., technology stocks) Technology Fund's performance will be more susceptible to any economic, business or other developments which affect the technology sector. The technology sector may be significantly affected by intense competition, rapid obsolescence, failure to obtain, or delay in obtaining financing or regulatory approval, the success or failure of research and development, product capability and customer preference. In addition, each Fund has the ability to invest in other types of securities, including principally derivative contracts and hybrid instruments, and in the case of MDT Fund, securities of other investment companies, including exchange-traded funds. The following are some additional risks of these additional categories of principal investments: * RISKS OF INVESTING IN DERIVATIVE CONTRACTS AND HYBRID INSTRUMENTS. A Fund's use of derivative contracts and hybrid instruments involves risks different from, or possibly greater than, the risks associated with investing directly in stocks. In addition to stock market and currency risks, investments in derivatives and hybrids may involve credit, liquidity and leverage risks. * CREDIT RISKS. Credit risk includes the possibility that a party to a transaction (such as a derivative 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. * LIQUIDITY RISKS. Liquidity risk refers to the possibility that the Fund may not be able to sell a security or close out a derivative contract when it wants to. * LEVERAGE RISKS. Leverage risk is created when an investment (such as a derivative transaction) exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund's risk of loss and potential for gain. * EXCHANGE-TRADED FUNDS. An investment in an ETF generally presents the same primary risks as an investment in a conventional fund (i.e., one that is not exchange-traded). As with traditional mutual funds, ETFs charge asset-based fees. The Fund will indirectly pay a proportional share of the asset-based fees of the ETFs in which the Fund invests. The net asset value of a Fund will fluctuate with the changes in the value of the ETFs in which the Fund invests. The change in value of the ETFs are due to the change in price of the securities in which the ETFs invest. Therefore, the Fund net asset value will be indirectly affected by the change in value of the securities in which the ETF invests.

However, the rate at which expenses are accrued during the fiscal year may not be constant and, at any particular point, may be greater or less than the stated average percentage. Although not contractually obligated to do so, the Adviser, administrator and shareholder services provider waived, reimbursed and/or did not charge certain amounts. These are shown below along with the net expenses the Fund actually paid for the fiscal year ended October 31, 2006. With respect to MDT Fund and MDT Fund Pro Forma Combined, the percentages shown are based on anticipated expenses for the fiscal year ending July 31, 2008. However, the rate at which expenses are accrued during the fiscal year may not be constant and, at any particular point, may be greater or less than the stated average percentage. Although not contractually obligated to do so (except as discussed in Note 3), the Adviser and administrator expect to waive and/or reimburse certain amounts. Additionally, the distributor expects not to charge the distribution (12b-1) fee for Class A Shares. These waivers, reimbursements and /or reductions are shown below along with the net expenses the Fund expects to pay for the fiscal year ending July 31, 2008.

The Adviser can terminate this voluntary waiver/reimbursement at any time. The management fee paid by the Fund (after the voluntary waiver/reimbursement) was 0.44% for the fiscal year ended October 31, 2006. 3 Under the investment advisory contract, the Adviser of MDT Fund and MDT Fund Pro Forma Combined is obligated to waive all or a portion of its investment advisory fee which it is otherwise entitled to receive, and/or reimburse other operating expenses (excluding interest, taxes and brokerage commissions), in order to limit the aggregate annual operating expenses for the Fund's Class A Shares to not more than 2.05% of its daily net assets. Any waivers and expense reduction by the administrator and/or distributor that reduce such expenses (as discussed elsewhere in these notes) may have the effect of reducing the amount to be waived or reimbursed by the Adviser pursuant to the contractual commitment. This commitment will expire on December 8, 2008. Pursuant to this contractual commitment, the Adviser of MDT Fund expects to waive its management fee for the fiscal year ending July 31, 2008. The management fee paid by MDT Fund (after the contractual waiver) is expected to be 0.00% for the fiscal year ending July 31, 2008.

Additionally, the Adviser expects to voluntarily waive a portion of the management fee for the fiscal year ending July 31, 2008. The management fee paid by MDT Fund Pro Forma Combined (after the contractual and voluntary waivers) is expected to be 0.10% for the fiscal year ending July 31, 2008. 4 With respect to MDT Fund, Class A Shares did not pay or accrue the distribution (12b-1) fee for the fiscal year ended July 31, 2007. With respect to MDT Fund and MDT Fund Pro Forma Combined, although not contractually obligated to do so, the distributor expects to voluntarily elect not to charge, and therefore the Fund will not accrue, the distribution (12b-1) fee for the Class A Shares for the fiscal year ending July 31, 2008. 5 With respect to Technology Fund, this includes a shareholder services/account administration fee which is used to compensate intermediaries for shareholder services or account administrative services.

The "y" axis reflects the "% Total Return" beginning with "-60%" and increasing in increments of 10% up to 60%. The "x" axis represents calculation periods from the earliest first full calendar year end of the Technology Fund's Start of Performance through the calendar year ended 2006. The light gray shaded chart features seven distinct vertical bars, each shaded in black, and each visually representing by height the total return percentages for the calendar year. The calculated total return percentage for the Technology Fund is stated at the top of each respective bar for the calendar years ended 2000 through 2006. The percentages notes are (45.18)%, (46.53)%, (39.85)%, 56.23%, 5.84%, 0.37%, and 4.24%, respectively. THE TOTAL RETURNS SHOWN IN THE BAR CHART DO NOT REFLECT THE PAYMENT OF ANY SALES CHARGES OR RECURRING SHAREHOLDER ACCOUNT FEES. IF THESE CHARGES OR FEES HAD BEEN INCLUDED, THE RETURNS SHOWN WOULD HAVE BEEN LOWER. THE FUND'S CLASS A SHARES TOTAL RETURN FOR THE NINE-MONTH PERIOD FROM JANUARY 1, 2007 TO SEPTEMBER 30, 2007 WAS 20.35%. WITHIN THE PERIOD SHOWN IN THE BAR CHART, THE FUND'S CLASS A SHARES HIGHEST QUARTERLY RETURN WAS 25.71% (QUARTER ENDED JUNE 30, 2003).

Return Before Taxes is shown for all classes. In addition, Return After Taxes is shown for the Fund's Class A Shares to illustrate the effect of federal taxes on Fund returns. Actual after-tax returns depend on each investor's personal tax situation, and are likely to differ from those shown. The table also shows returns for the NASDAQ Composite Index (NCI), a broad-based market index, the Merrill Lynch 100 Technology Index (MLT 100), an index measuring the performance of a cross section of large, actively traded technology stocks and ADRs, and the Lipper Science & Technology Funds Average (LSTFA), an average of funds with similar objectives. The LSTFA returns do not reflect taxes and sales charges but do reflect other expenses and fees that the SEC requires to be reflected in a fund's performance. Index returns do not reflect taxes, sales charges, expenses or other fees that the SEC requires to be reflected in the fund's performance. Indexes are unmanaged and it is not possible to invest directly in an index or an average. - 5 - (For the periods ended December 31, 2006) 1 YEAR 5 YEAR START OF PERFORMANCE1 CLASS A SHARES: Return Before Taxes (1.57)% (0.49)% (8.24)% Return After Taxes on Distributions2 (1.57)% (0.49)% (8.25)% Return After Taxes on Distributions and Sale of Fund Shares2 (1.02)% (0.41)% (6.68)% CLASS B SHARES: Return Before Taxes (2.02)% (0.51)% (8.21)% CLASS C SHARES: Return Before Taxes3 1.50% (0.30)% (8.34)% NCI4 10.39% 4.98% (1.64)% MLT 1004 11.24% 4.70% (1.90)% LSTFA5 7.28% 1.17% (7.98)% 1 The Fund's Class A, Class B and Class C Shares start of performance date was September 21, 1999. 2 After-tax returns are calculated using a standard set of assumptions.

A discussion of the review of Technology Fund's investment advisory contract by the Board of Trustees of the Trust is available in Technology Fund's Semi-Annual Report dated April 30, 2007. A discussion of the review of MDT Fund's investment advisory contract by the Board of Trustees of MDT Trust is available in MDT Fund's Annual Report dated July 31, 2007. ADMINISTRATIVE FEES Federated Administrative Services ("FAS"), an affiliate of the Technology Adviser and MDT Adviser, serves as administrator to each of Technology Fund and MDT Fund and provides certain administrative personnel and services as necessary. FAS provides these services at an annual rate based on the average aggregate daily net assets of the Funds and most of the other Federated funds advised by the Advisers or their affiliates. The rate charged by FAS is based on a scale that ranges from 0.150% on the first $5 billion of average aggregate daily nets assets to 0.075% on assets over $20 billion. FAS' minimum annual administrative fee with respect to each Fund is $150,000 per portfolio and $40,000 per each additional class of shares. FAS may choose voluntarily to waive a portion of its fee. The net administrative fee expense charged by FAS for Technology Fund's fiscal year ended October 31, 2007 was $185,638, or 0.29% of average daily net assets. The administrative fee for the period from July 15, 2006 through July 31, 2006 was pro-rated for MDT Fund. During the period from July 15, 2006 through July 31, 2006, FAS contractually agreed to waive the portion of its fee which it would otherwise be entitled to receive from MDT Fund. The net administrative fee expense charged by FAS for MDT Fund for its fiscal year ended July 31, 2007 was $123,643 or 2.39% of average daily net assets. The Funds and their affiliated service providers may pay fees as described below to financial intermediaries (such as broker-dealers, banks, investment advisers or third-party administrators) whose customers are shareholders of the Funds. SERVICE FEES Technology Fund and MDT Fund may pay a Service Fee of up to 0.25% of average net assets to financial intermediaries, or to Federated Shareholder Services Company (FSSC), a subsidiary of Federated, for providing services to shareholders and maintaining shareholder accounts. Intermediaries that receive Service Fees may include a company affiliated with management of Federated. If a financial intermediary receives Service Fees on an account, it is not eligible to also receive Account Administration Fees on the same account. RULE 12B-1 FEES Federated Securities Corp. ("FSC"), an affiliate of the Advisers, is the principal distributor (the "Distributor") for shares of the Funds. Both Funds have adopted a Rule 12b-1 Distribution Plan (the "Distribution Plan") which allows them to pay marketing fees of up to 0.25% of average net assets of the Fund's Class A Shares and 0.75% of average net assets of the Fund's Class B Shares and Class C Shares to the Distributor for the sale, distribution, administration and customer servicing of the Fund's Class A, Class B and Class C Shares. When the Distributor receives Rule 12b-1 Fees, it may pay some or all of them to financial intermediaries whose customers purchase Shares. Because the Fund pays marketing fees in respect of these share classes on an ongoing basis, your investment cost in these shares may be higher over time than would be an investment in other shares with different sales charges and marketing fees. ACCOUNT ADMINISTRATION FEES The Funds may pay Account Administration Fees of up to 0.25% of average net assets to banks that are not registered as broker-dealers or investment advisers for providing administrative services to the Funds and shareholders. If a financial intermediary receives Account Administration Fees on an account, it is not eligible to also receive Service Fees or Recordkeeping Fees on that same account. RECORDKEEPING FEES The Funds may pay Recordkeeping Fees on an average net assets basis or on a per account per year basis to financial intermediaries for providing recordkeeping services to the Funds and shareholders. If a financial intermediary receives Recordkeeping Fees on an account, it is not eligible to also receive Account Administration Fees or Networking Fees on that same account. NETWORKING FEES The Funds may reimburse Networking Fees on a per account per year basis to financial intermediaries for providing administrative services to the Funds and shareholders on certain non-omnibus accounts. If a financial intermediary receives Networking Fees on an account, it is not eligible to also receive Recordkeeping Fees on that same account. ADDITIONAL PAYMENTS TO FINANCIAL INTERMEDIARIES The Distributor may pay out of its own resources amounts (including items of material value) to certain financial intermediaries that support the sale of Shares or provide services to the Funds' shareholders. The amounts of these payments could be significant, and may create an incentive for the financial intermediary or its employees or associated persons to recommend or sell Shares of the Funds to you. In some cases, such payments may be made by or funded from the resources of companies affiliated with the Distributor (including the Advisers). These payments are not reflected in the fees and expenses listed in the fee table section of the Funds' prospectuses and described above because they are not paid by the Funds. These payments are negotiated and may be based on such factors as the number or value of Shares that the financial intermediary sells or may sell; the value of client assets invested; or the type and nature of services or support furnished by the financial intermediary. These payments may be in addition to payments made by the Funds to the financial intermediary under a Rule 12b-1 Plan and/or Service Fees arrangement. In connection with these payments, the financial intermediary may elevate the prominence or profile of the Funds and/or other Federated funds within the financial intermediary's organization by, for example, placement on a list of preferred or recommended funds, and/or granting the Distributor preferential or enhanced opportunities to promote the funds in various ways within the financial intermediary's organization. You can ask your financial intermediary for information about any payments it receives from the Distributor or the Fund and any services provided. PURCHASE, REDEMPTION AND EXCHANGE PROCEDURES The transfer agent and dividend-disbursing agent for both Funds is State Street Bank and Trust Company. Procedures for the purchase, exchange, and redemption of MDT Fund's Shares are substantially the same as the procedures applicable to the purchase, exchange, and redemption of Technology Fund's Shares. Reference is made to the Prospectuses of MDT Fund and the Prospectus of Technology Fund, each of which is incorporated by reference, for a complete description of the purchase, exchange, and redemption procedures applicable to MDT Fund's Shares and Technology Fund's Shares, respectively. Set forth below is a brief description of the significant purchase, exchange, and redemption procedures applicable to MDT Fund's and Technology Fund's Shares. PURCHASES Shares of Technology Fund and MDT Fund may be purchased any day the New York Stock Exchange (NYSE) is open. When the Funds receive your transaction request in proper form (as described in the Prospectus), it is processed at the next calculated net asset value (NAV) plus any applicable front-end sales charge (public offering price). When the Funds hold securities that trade in foreign markets on days the NYSE is closed, the value of the Funds' assets may change on days you cannot purchase or redeem Shares. NAV is determined as of the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time) each day the NYSE is open. Purchases of both Funds may be made through an intermediary, directly from the Fund or through an exchange from another Federated fund. Each Fund reserves the right to reject any request to purchase or exchange shares. Purchasers of both Funds' Class A Shares incur a front-end sales charge of up to 5.50% of the public offering price on purchase amounts less than $1 million. The sales charges are subject to the breakpoint discounts and rights of accumulation, which are identical for each Fund and are described in each Fund's prospectus for its Class A Shares. For purchases of $1 million or more, a contingent deferred sales charge of 0.75% of the redemption amount applies to Class A Shares redeemed up to 24 months after purchase under certain investment programs where a financial intermediary received an advance payment on the transaction. - 14 - There is no front-end sales charge upon purchase of Class B or Class C Shares. However, upon redemption, holders of both MDT Fund's and Technology Fund's Class B Shares may incur a contingent deferred sales charge, or CDSC. The CDSC for Class C Shares is 1% on Class C Shares redeemed within 12 months of the purchase date. The CDSC on Class B Shares varies according to the length of time the Class B Shares are held as follows: ----------------------------------------------------- |SHARES HELD UP TO:|CONTINGENT DEFERRED SALES CHARGE| ----------------------------------------------------- |1 Year |5.50% | ----------------------------------------------------- |2 Years |4.75% | ----------------------------------------------------- |3 Years |4.00% | ----------------------------------------------------- |4 Years |3.00% | ----------------------------------------------------- |5 Years |2.00% | ----------------------------------------------------- |6 Years |1.00% | ----------------------------------------------------- |7 Years or More |0.00% | ----------------------------------------------------- The CDSC is calculated using the Share price at the time of purchase or redemption, whichever is lower. The CDSC on each Fund's Class B and Class C Shares may be reduced or eliminated in the circumstances, which are identical for each Fund, described in the Prospectuses for the Funds' Class B and Class C Shares. The following chart shows the minimum initial and subsequent investment minimum amounts for each Fund: FUND INITIAL SUBSEQUENT SYSTEMATIC INVESTMENT PROGRAM INITIAL/SUBSEQUENT INVESTMENT INVESTMENT MINIMUM INVESTMENT MINIMUM MINIMUM TECHNOLOGY FUND/ MDT FUND - CLASS $1,500 $100 $50/$50 A SHARES TECHNOLOGY FUND/ MDT FUND - CLASS $1,500 $100 $50/$50 B SHARES TECHNOLOGY FUND/ MDT FUND - CLASS $1,500 $100 $50/$50 C SHARES For Trustees and Officers of the Federated MDT Funds or of the former MDT Funds, shareholders of any MDT Fund as of August 26, 2006, employees of MDT Adviser, and former members of the Memorial Drive Trust, the required minimum initial investment of MDT Fund shares is $1,000. Due to the high cost of maintaining accounts with low balances, accounts may be closed if redemptions or exchanges 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. In addition to purchases by wire and by check, both Funds offer the following purchase options: (i) Through an Exchange: Shareholders may purchase through an exchange from the same class of another Federated fund. You must meet the minimum initial investment requirement for purchasing shares and both accounts must have identical registrations; (ii) By Automated Clearing House (ACH): Once you have opened your account, you may purchase additional shares through a depository institution that is an ACH member; (iii) Systematic Investment Program: all classes can purchase shares by using the Systematic Investment Program (SIP). REDEMPTIONS AND EXCHANGES Redemptions and exchanges of each Fund may be made through a financial intermediary or directly from the Fund by telephone or by mailing a written request. Shares of both Funds may be redeemed for cash or exchanged for shares of the same class of other Federated funds on days on which the Fund computes its NAV. Each Fund has an exchange privilege that allows shareholders to exchange shares of the Fund into shares of the same class of another Federated fund. Any questions about the foregoing procedures may be directed to, and assistance in effecting purchases, redemptions or exchanges of each Fund may be obtained by calling, the Funds at 1-800-341-7400. DIVIDENDS AND DISTRIBUTIONS; TAX INFORMATION; FREQUENT TRADING; PORTFOLIO HOLDINGS DISCLOSURE POLICY DIVIDENDS AND DISTRIBUTIONS Both Funds declare and pay any dividends annually to shareholders. In addition, both Funds pay any capital gains at least annually. Dividends and capital gains distributions will be automatically reinvested in additional shares without a sales charge, unless you elect a cash payment. TAX INFORMATION It is anticipated that both Funds' distributions will be primarily capital gains. The Funds' distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable at different rates depending on the source of dividend income. Capital gains are taxable at different rates depending upon the length of time the Fund holds its assets. Redemptions and exchanges are taxable sales. FREQUENT TRADING Frequent or short-term trading into and out of the Funds can have adverse consequences for the Funds and shareholders who use the Funds as a long-term investment vehicle. Such trading in significant amounts can disrupt the Funds' investment strategies (e.g., by requiring them to sell investments at inopportune times or maintain excessive short-term or cash positions to support redemptions), increase brokerage and administrative costs and affect the timing and amount of taxable distributions by the Funds. Investors engaged in such trading may also seek to profit by anticipating changes in a Fund's NAV in advance of the time as of which NAV is calculated. Each Fund's Board has approved policies and procedures intended to discourage excessive frequent or short-term trading of its shares. These policies and procedures are identical for both Funds and are described in each Fund's Prospectus, incorporated herein by reference. PORTFOLIO HOLDINGS DISCLOSURE POLICIES Each Fund's SAI contains a description of the Fund's policies and procedures with respect to the disclosure of its portfolio securities. The SAIs are available on Federated's website at FederatedInvestors.com. INFORMATION ABOUT THE REORGANIZATION DESCRIPTION OF THE PLAN OF REORGANIZATION The Plan provides for the Reorganization to occur on the Closing Date, which is expected to be on or after February 22, 2008. On the Closing Date, all of the assets of Technology Fund will be transferred to MDT Fund. In exchange for the transfer of these assets, MDT Fund will simultaneously issue to Technology Fund a number of full and fractional Class A Shares, Class B Shares and Class C Shares of MDT Fund equal in value to the aggregate NAV of the Class A, Class B Shares and Class C Shares, respectively, of Technology Fund calculated as of 4:00 p.m. on the Closing Date. The value of Technology Fund's assets to be acquired by MDT Fund shall be the value of such assets at the Closing Date of the Reorganization using the valuation procedures set forth in MDT Fund's Declaration of Trust and its current Prospectus and SAI, or such other valuation procedures as Technology Fund and MDT Fund shall mutually agree. There are no material differences between the valuation procedures of Technology Fund and MDT Fund. The Funds generally value equity securities according to the last sale price or official closing price reported in the market in which they are primarily traded (either a national securities exchange or the over-the-counter market). Futures contracts and options are generally valued at market values established by the exchanges on which they are traded at the close of trading on such exchanges. The Funds generally value total return swaps based upon a valuation model determined by management incorporating underlying reference indexes, interest rates, yield curves and other market data or factors. The Funds value investments in other registered open-end investment companies at NAV. If prices are not available from an independent pricing service, securities and derivative contracts traded in the over-the-counter market are generally valued according to the mean between the last bid and the last asked price for the security or contract as provided by an investment dealer or other financial institution that deals in the security or contract. Technology Fund will discharge all of its liabilities and obligations prior to consummation of the Reorganization. Following the transfer of its assets in exchange for Class A Shares, Class B Shares and Class C Shares of MDT Fund, Technology Fund will distribute the Class A Shares, Class B Shares and Class C Shares of MDT Fund pro rata to shareholders of record of Class A Shares, Class B Shares and Class C Shares of Technology Fund, respectively, in complete liquidation of Technology Fund. Shareholders of Technology Fund owning shares on the Closing Date of the Reorganization will receive that number of Class A Shares, Class B Shares and Class C Shares, respectively, of MDT Fund which have the same aggregate value as the shareholder held in Technology Fund immediately before the Reorganization. This distribution will be accomplished by the establishment of accounts in the names of Technology Fund's shareholders on the share records of MDT Fund's transfer agent. MDT Fund does not issue share certificates to shareholders. Following the consummation of the Reorganization, Technology Fund will then be terminated; the Trust will amend its Declaration of Trust to remove Technology Fund as a series of the Trust. The transfer of shareholder accounts from Technology Fund to MDT Fund will occur automatically. It is not necessary for Technology Fund shareholders to take any action to effect the transfer. PLEASE DO NOT ATTEMPT TO MAKE THE TRANSFER YOURSELF. IF YOU DO SO, YOU MAY DISRUPT THE MANAGEMENT OF THE FUNDS' PORTFOLIOS, AND YOU MAY INCUR SALES CHARGES THAT YOU WOULD NOT INCUR IN THE REORGANIZATION. The Plan contains customary representations, warranties and conditions. The Plan provides that the consummation of the Reorganization is conditioned upon, among other things: (i) approval of the Reorganization by Technology Fund's shareholders; and (ii) the receipt by the Trust and MDT Trust of an opinion to the effect that the Reorganization will be tax-free to Technology Fund, its shareholders and MDT Fund. The Plan may be terminated if, before the Closing Date, any of the required conditions have not been met, the representations and warranties are not true or the Board or the Trustees determines that the Reorganization is not in the best interest of the shareholders of Technology Fund or MDT Fund, respectively. The expenses of the Reorganization will be paid by MDT Adviser or its affiliates. Reorganization expenses include, without limitation: expenses associated with the preparation and filing of this Prospectus/Proxy Statement; postage; printing; accounting fees; legal fees incurred by Technology Fund and MDT Fund; proxy solicitation costs; and other related administrative or operational costs. Any brokerage charges associated with the purchase or disposition of portfolio securities by Technology Fund prior to the Reorganization will be borne by Technology Fund. The foregoing brief summary of the Plan is qualified in its entirety by the terms and provisions of the Plan, a copy of which is attached hereto as Exhibit A and incorporated herein by reference. DESCRIPTION OF MDT FUND'S SHARE CLASSES AND CAPITALIZATION Class A Shares, Class B Shares and Class C Shares of MDT Fund to be issued to shareholders of Technology Fund's Class A Shares, Class B Shares and Class C Shares, respectively, under the Plan will be fully paid and non-assessable when issued, transferable without restriction and will have no preemptive or conversion rights. Reference is hereby made to the Prospectuses of MDT Fund provided herewith for additional information about Class A Shares, Class B Shares and Class C Shares of MDT Fund. The following tables sets forth the unaudited capitalization of MDT Fund's and Technology Fund's Class A Shares, Class B Shares and Class C Shares as of November 12, 2007 and on a pro forma combined basis after giving effect to the Reorganization as of that date: Net Asset Value Per Fund Total Net Shares Share Assets* Outstanding Federated Technology Fund - Class A Shares $20,481,054 3,305,290 $6.20 Adjustments - (1,702,704) Federated MDT Small Cap Growth Fund - Class A Shares $1,623,213 126,981 $12.78 Federated MDT Small Cap Growth Fund, Pro Forma Combined - Class A Shares $22,104,267 1,729,567 $12.78 Federated Technology Fund - Class B Shares $31,154,934 5,345,311 $5.83 Adjustments - (2,922,688) Federated MDT Small Cap Growth Fund - Class B Shares $0 0 $12.86 Federated MDT Small Cap Growth Fund, Pro Forma Combined - Class B Shares $31,154,934 2,422,623 $12.86 Federated Technology Fund - Class C Shares $6,521,704 1,117,944 $5.83 Adjustments - (599,526) Federated MDT Small Cap Growth Fund - Class C Shares $1,265,864 100,663 $12.58 Federated MDT Small Cap Growth Fund, Pro Forma Combined - Class C Shares $7,787,568 619,081 $12.58 * Does not reflect additional $26,120,241 of net assets of Federated MDT Small Cap Growth Fund represented by the Institutional Share class. FEDERAL TAX CONSEQUENCES As a condition to the Reorganization, MDT Fund and Technology Fund will receive an opinion of counsel to the effect that, on the basis of the existing provisions of the Internal Revenue Code of 1986, as amended (the "Code"), current administrative rules and court decisions, for federal income tax purposes: {circle}the Reorganization as set forth in the Plan will constitute a tax- free reorganization under section 368(a) of the Code, and Technology Fund and MDT Fund each will be a "party to a reorganization" within the meaning of section 368(b) of the Code; {circle}no gain or loss will be recognized by MDT Fund upon its receipt of Technology Fund's assets in exchange for Class A Shares, Class B Shares and Class C Shares of MDT Fund; {circle}no gain or loss will be recognized by Technology Fund upon transfer of its assets to MDT Fund in exchange for MDT Fund Class A Shares, Class B Shares and Class C Shares or upon the distribution of MDT Fund's shares to Technology Fund's shareholders in exchange for their Class A Shares, Class B Shares and Class C Shares, respectively; {circle}no gain or loss will be recognized by shareholders of Technology Fund upon exchange of their Class A Shares, Class B Shares and Class C Shares for Class A Shares Class B Shares and Class C Shares, respectively, of MDT Fund; {circle}the aggregate tax basis of the Class A Shares, Class B Shares and Class C Shares of MDT Fund received by each shareholder of Technology Fund pursuant to the Plan will be the same as the aggregate tax basis of the shares of Technology Fund held by such shareholder immediately prior to the Reorganization; {circle}the holding period of MDT Fund's Class A Shares, Class B Shares and Class C Shares received by each shareholder of Technology Fund pursuant to the Plan will include the period during which Technology Fund Class A Shares, Class B Shares and Class C Shares, respectively, exchanged therefor were held by such shareholder, provided the shares of Technology Fund were held as capital assets on the date of the Reorganization; {circle}the tax basis of the assets of Technology Fund acquired by MDT Fund will be the same as the tax basis of such assets to Technology Fund immediately prior to the Reorganization; and {circle}the holding period of Technology Fund's assets in the hands of MDT Fund will include the period during which those assets were held by Technology Fund. Based on projections as of __________, Technology Fund will have approximately $498 million of capital loss carryforwards available to be transferred to MDT Fund in the Reorganization. It is anticipated that any capital loss carryforwards of Technology Fund which were generated prior to the Reorganization and which are unutilized at the time of the Reorganization will remain available to MDT Fund following the Reorganization, subject to any applicable limitations under the Code, (including the annual expiration of the various carryforward periods through 2010). The foregoing opinion may state that no opinion is expressed as to the effect of the Reorganization on MDT Fund, Technology Fund or Technology Fund's shareholders with respect to any asset as to which unrealized gain or loss is required to be recognized for federal income tax purposes at the end of a taxable year (or on the termination or transfer thereof) under a mark-to-market system of accounting. Shareholders of Technology Fund should consult their tax advisors regarding the effect, if any, of the Reorganization in light of their individual circumstances. Because the foregoing discussion only relates to the federal income tax consequences of the Reorganization, those shareholders also should consult their tax advisors about state and local tax consequences, if any, of the Reorganization. Because Technology Fund has a capital loss carry-forward greatly in excess of its unrealized capital gains, there will be no capital gains distribution by Technology Fund before the Closing Date, even if capital gains are realized in dispositions of portfolio securities in connection with the Reorganization. Technology Fund will distribute to shareholders any previously undistributed ordinary income accumulated prior to the Reorganization. - 15 - COMPARATIVE INFORMATION ON SHAREHOLDER RIGHTS Both the Trust and MDT Trust (each the "Trust" and collectively the "Trusts") are open-end, management investment companies.

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.

LEGAL PROCEEDINGS Since October 2003, Federated and related entities (collectively, "Federated"), and various Federated funds ("Funds"), have been named as defendants in several class action lawsuits now pending in the United States District Court for the District of Maryland. The lawsuits were purportedly filed on behalf of people who purchased, owned and/or redeemed shares of Federated-sponsored mutual funds during specified periods beginning November 1, 1998. The suits are generally similar in alleging that Federated engaged in illegal and improper trading practices including market timing and late trading in concert with certain institutional traders, which allegedly caused financial injury to the mutual fund shareholders. These lawsuits began to be filed shortly after Federated's first public announcement that it had received requests for information on shareholder trading activities in the Funds from the SEC, the Office of the New York State Attorney General ("NYAG"), and other authorities. In that regard, on November 28, 2005, Federated announced that it had reached final settlements with the SEC and the NYAG with respect to those matters. Specifically, the SEC and NYAG settled proceedings against three Federated subsidiaries involving undisclosed market timing arrangements and late trading. The SEC made findings: that Federated Investment Management Company ("FIMC"), an SEC-registered investment adviser to various Funds, and Federated Securities Corp., an SEC-registered broker-dealer and distributor for the Funds, violated provisions of the Investment Advisers Act and Investment Company Act by approving, but not disclosing, three market timing arrangements, or the associated conflict of interest between FIMC and the funds involved in the arrangements, either to other fund shareholders or to the funds' board; and that Federated Shareholder Services Company, formerly an SEC-registered transfer agent, failed to prevent a customer and a Federated employee from late trading in violation of provisions of the Investment Company Act. The NYAG found that such conduct violated provisions of New York State law. Federated entered into the settlements without admitting or denying the regulators' findings. As Federated previously reported in 2004, it has already paid approximately $8.0 million to certain funds as determined by an independent consultant. As part of these settlements, Federated agreed to pay disgorgement and a civil money penalty in the aggregate amount of an additional $72 million and, among other things, agreed that it would not serve as investment adviser to any registered investment company unless (i) at least 75% of the fund's directors are independent of Federated, (ii) the chairman of each such fund is independent of Federated, (iii) no action may be taken by the fund's board or any committee thereof unless approved by a majority of the independent trustees of the fund or committee, respectively, and (iv) the fund appoints a "senior officer" who reports to the independent trustees and is responsible for monitoring compliance by the fund with applicable laws and fiduciary duties and for managing the process by which management fees charged to a fund are approved. The settlements are described in Federated's announcement which, along with previous press releases and related communications on those matters, is available in the "About Us" section of Federated's website at FederatedInvestors.com. Federated and various Funds have also been named as defendants in several additional lawsuits, the majority of which are now pending in the United States District Court for the Western District of Pennsylvania, alleging, among other things, excessive advisory and Rule 12b-1 fees. The Board of the Funds has retained the law firm of Dickstein Shapiro LLP to represent the Funds in these lawsuits. Federated and the Funds, and their respective counsel, are reviewing the allegations and intend to defend this litigation. Additional lawsuits based upon similar allegations may be filed in the future. The potential impact of these lawsuits, all of which seek unquantified damages, attorneys' fees, and expenses, and future potential similar suits is uncertain. Although we do not believe that these lawsuits will have a material adverse effect on the Funds, there can be no assurance that these suits, ongoing adverse publicity and/or other developments resulting from the regulatory investigations will not result in increased Fund redemptions, reduced sales of Fund shares, or other adverse consequences for the Funds.

PROXIES, QUORUM AND VOTING AT THE SPECIAL MEETING Only shareholders of record on the Record Date will be entitled to vote at the Special Meeting. Each Class A, Class B and Class C Share of Technology Fund is entitled to one vote. Fractional shares are entitled to proportionate shares of one vote. The votes of shareholders of MDT Fund are not being solicited since their approval is not required in order to effect the Reorganization. Any person given 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 Trust. 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 APPROVAL OF THE AGREEMENT AND PLAN OF REORGANIZATION. In order to hold the Special Meeting, a "quorum" of shareholders of Technology Fund must be present. Due to the requirements of the 1940 Act discussed in the next paragraph, holders of more than 50% of the total number of Class A Shares, Class B Shares and Class C Shares of Technology Fund entitled to vote, present in person or by proxy, shall be required to constitute a quorum for the purpose of voting on the proposal to approve the Agreement and Plan of Reorganization. Holders of one-fourth the total number of Class A, Class B and Class C Shares of Technology Fund entitled to vote, present in person or by proxy, shall be required ot constitute a quorum for the purpose of transacting any other business which may come before the meeting. Shareholder approval with respect to the proposal requires the affirmative vote of "a majority of the outstanding voting securities" as defined in the 1940 Act. This vote requires the lesser of (A) 67% or more of the Class A Shares, Class B Shares and Class C Shares of Technology Fund present at the meeting, voting together as a single class, if the shareholders of more than 50% of the outstanding Class A Shares, Class B Shares and Class C Shares of Technology Fund are present or represented by proxy; or (B) more than 50% of the outstanding Class A Shares, Class B Shares and Class C Shares of Technology Fund, voting together as a single class.

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 proposal. If a quorum is not present, the persons named as proxies may vote those proxies that have been received to adjourn the Special Meeting from time to time (to a date not later than 120 days after the original record date) without further notice other than by announcement to be given at the meeting until a quorum is met. In the event that a quorum is present but sufficient votes in favor of the proposal 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 the proposal. All such adjournments will require the affirmative vote of a majority of the shares present in person or by proxy at the session of the Special Meeting to be adjourned. The persons named as proxies will vote AGAINST an adjournment those proxies that they are required to vote against the proposal, and will vote in FAVOR of such an adjournment all other proxies that they are authorized to vote. A shareholder vote may be taken on the proposal in this Prospectus/Proxy Statement prior to any such adjournment if sufficient votes have been received for approval.

By Order of the Board of Directors, /s/ John W. McGonigle John W. McGonigle, Secretary January 23, 2008 - 19 - - 20 - EXHIBIT B Management's Discussion of Fund Performance of Technology Fund Management's Discussion of Fund Performance The Federated Technology Fund produced a total return, based on net asset value, of 6.35% for the fund's Class A Shares, 5.63% for the fund's Class B Shares and 5.63% for the fund's Class C Shares for the fiscal year ended October 31, 2006. This return trailed the 10.21% average return for the fund's peers in the Lipper Science & Technology Fund category 1 and the 16.02% return for the Merrill Lynch Technology 100 Index (the "MLT 100") 2 for the same period. The fund's total return for the fiscal year reflected actual cash flows, transaction costs and other expenses which were not reflected in the total return of the MLT 100. MARKET OVERVIEW Technology stocks, as measured by the MLT 100, performed reasonably well through the first half of the fund's fiscal year as the group continued to report strong earnings and solid fundamentals. However, in early May the market's concerns regarding inflation, the Federal Reserve's interest rate policy, oil prices, and geopolitical tensions in Iran and North Korea began to pressure the dynamic Technology group as investors worried that these issues would slow economic growth and therefore Information Technology spending. As a result Technology group sold off dramatically from early May through July. The sector performed well into the fund's fiscal year end as prior market concerns began to ease, earnings and fundamentals continued to be quite robust, and valuations remained attractive. Overall, Technology stocks performed basically inline with the S&P 500 Index 3 over the reporting period. 1 Lipper figures represent the average of the total returns reported by all the mutual funds designated by Lipper, Inc. as falling into the category indicated. They do not reflect sales charges. 2 The Merrill Lynch Technology 100 Index is an equal dollar-weighted index of 100 stocks designed to measure the performance of a cross section of large, actively traded technology stocks and American Depositary Receipts (ADRs). The index was developed with a base value of 200 as of January 30, 1998. Indexes are unmanaged and it is not possible to invest directly in an index. 3 The S&P 500 Index is an unmanaged capitalization-weighted index of 500 stocks designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries. It is not possible to invest directly in an index. PERFORMANCE REVIEW The fund suffered from its larger-cap bias, its underweighting versus the MLT 100 in high beta sectors such as semiconductors, and its focus on valuation. The fund's performance versus the MLT 100 was hurt by weak security selection in Semiconductors/Semi-Cap Equipment and Communications Equipment. The fund's performance was also hurt by its underweight in Semiconductors and Enterprise Hardware, as both slightly outperformed Technology sector on an absolute basis over the reporting period. The fund benefited from its overweighting and good security selection in the Biotech and Life Sciences, Internet and Video Game and Software sectors. Fund management continued to focus on enterprise IT spending versus consumer technology during the reporting period. The fund had an overweight exposure to ELECTRONIC ARTS, INC. , ACTIVISION, INC. , GAMESTOP CORP. , and MICROSOFT CORP. , along with several of the component suppliers of the new video game consoles. The fund increased its exposure to the Internet group as valuations became more attractive over the past fiscal year and added to positions in GOOGLE INC. , EBAY , INC. and YAHOO, INC. while also adding new positions in NETFLIX, INC. and AMAZON.COM, INC. during the reporting period. With respect to enterprise related technology spending, the fund continued to have an overweight exposure to faster growth areas such as Storage and Software during the reporting period: in Storage through investments in EMC CORP. , NETWORK APPLIANCE, INC. and the recent IPO of COMMVAULT SYSTEMS, INC. ; and in Software through investments in BEA SYSTEMS, INC., ANSYS, INC., ADOBE SYSTEMS, INC. and ORACLE CORP. The Communications Equipment area became a larger focus for the fund over the past fiscal year as the build-out of 3G (a wireless data service), IMS (Internet Protocol Multimedia Subsystem), and IPTV (Internet television service) finally got underway. With respect to enterprise services, the fund continued to focus on the outsourcing theme with two large holdings during the reporting period: PAYCHEX, INC. (a large payroll and HR outsourcer focused on the SMB market) and COGNIZANT TECHNOLOGY SOLUTIONS CORP. (a leading provider of offshore application maintenance and development services in India). Finally, the fund continued to invest in the exciting, high growth Biotech and Life Sciences area through companies such as CEPHALON, INC. , SHIRE PLC , and MEDICIS PHARMACEUTICAL CORP. The securities that most positively impacted the fund included CISCO SYSTEMS, INC. (average 2.8% of net assets) a leading provider of communications equipment that gained 38% over the reporting period; CEPHALON, INC. (0.6% of net assets) a developer of biopharma products to treat neurological disorders and cancer that gained 72% during the reporting period; COGNIZANT TECHNOLOGY SOLUTIONS CORP. (2.0% of net assets) a leading provider of offshore IT services that was up 71% during the reporting period; ORACLE CORP. (1.8% of net assets) a leading provider of infrastructure software that was up over 45% during the reported period; AMDOCS (1.9% of net assets) a leading provider of telecommunications software and related services that was up over 46% in the reporting period; SHIRE PLC (1.6% of net assets) a developer and marketer of therapeutic prescription medicines that was up 54% over the reporting period; and RESEARCH IN MOTION LTD. (1.0% of net assets) the developer of the popular Blackberry device that was up 91% during the reporting period. The securities that most negatively impacted the fund during the reporting period included MARVELL TECHNOLOGY GROUP LTD. (1.7% of net assets) a communication integrated circuit provider; SYMANTEC CORP. (0.9% of net assets) a security software provider; DELL, INC. (1.5% of net assets) a leading PC and server manufacturer; and CHARTERED SEMICONDUCTOR MANUFACTURING LTD. (0.2% of net assets) a provider of wafer fabrication services to semiconductor suppliers.

The Russell 3000{reg-trade-mark} Index, which represents the performance of the 3000 largest U.S. companies by market capitalization, finished the period up a solid 16.08%. Mid-cap stocks lead the way as demonstrated by the 18.93% return on the Russell Midcap{reg-trade-mark} Index4, which exceeded the 15.48% and 12.12% results for the Russell Top 200{reg-trade-mark} Index5 and the Russell 2000{reg-trade-mark} Index,6 respectively.

FUND PERFORMANCE The most positive contributor to the fund's performance relative to the Russell 2000{reg-trade-mark} Growth Index was its stock selection in the Industrials, Consumer Discretionary, Financials, and Health Care sectors. Additionally, the fund's underweight in the Financial Services sector contributed positively to relative performance. The fund's performance was negatively impacted by its stock selection in the Consumer Staples sector. The fund's stock selection and underweight in the Information Technology sector also detracted from relative performance. Individual stocks contributing to the fund's out performance relative to the Russell 2000{reg-trade-mark} Growth Index included: CROCS INC., CHAPARRAL STEEL CO., MANITOWOC INC., PRICELINE.COM INC., and WELLCARE GROUP INC.

INTRODUCTION The accompanying unaudited Pro Forma Combining Portfolios of Investments, Statements of Assets and Liabilities and Statements of Operations (Pro Forma Financial Statements) reflect the accounts of Federated Technology Fund (Technology Fund) and Federated MDT Small Cap Growth Fund (MDT Fund), for the period ended July 31, 2007. MDT Small Cap Growth Fund (the "Predecessor Fund") was reorganized into MDT Fund as of the close of business on December 8, 2006. Prior to the reorganization, MDT Fund had no investment operations. MDT Fund is the successor to the Predecessor Fund. For the purposes of these Pro Forma Financial Statements, the financial information covers the period from August 1, 2006 to July 31, 2007. These statements have been derived from the books and records utilized in calculating daily net asset values at July 31, 2007. The Pro Forma Financial Statements give effect to the proposed exchange of assets of Class A Shares, Class B Shares and Class C Shares of Technology Fund for Class A Shares, Class B Shares and Class C Shares of MDT Fund. Under generally accepted accounting principles, MDT Fund will be the surviving entity for accounting purposes with its historical cost of investment securities and results of operations being carried forward. The Pro Forma Financial Statements have been adjusted to reflect the anticipated advisory fee arrangement for the surviving entity. Certain other operating costs have also been adjusted to reflect anticipated expenses of the combined entity. Other costs which may change as a result of the reorganization are currently undeterminable. 3 FEDERATED TECHNOLOGY FUND FEDERATED MDT SMALL CAP GROWTH FUND PRO FORMA COMBINING PORTFOLIO OF INVESTMENTS JULY 31, 2007 (UNAUDITED) MDT FUND MDT FUND TECHNOLOGY MDT PRO FORMA TECHNOLOGY MDT PRO FORMA FUND COMBINED FUND FUND COMBINED FUND SHARES VALUE COMMON STOCKS - 99.6% ADVERTISING - 0.0% 0 2,243 2,243 1Greenfield Online, Inc. $0 $36,426 $36,426 AGRICULTURAL CHEMICALS - 0.2% 0 5,222 5,222 UAP Holding Corp. 0 141,882 141,882 APPAREL - 0.1% 0 952 952 1Carter's, Inc. 0 20,154 20,154 0 3,658 3,658 1Maidenform Brands, Inc. 0 65,771 65,771 0 85,925 85,925 AUTO ORIGINAL EQUIPMENT MANUFACTURERS - 0.1% 0 3,906 3,906 Sun Hydraulics Corp. 0 116,086 116,086 BEER - 0.2% 0 2,925 2,925 1The Boston Beer Co., Inc., Class A 0 119,223 119,223 BIOTECHNOLOGY - 0.2% 0 2,054 2,054 1Air Methods Corp. 0 78,257 78,257 0 1,032 1,032 1LifeCell Corp. 0 31,672 31,672 0 1,343 1,343 1PharmaNet Development Group, Inc. 0 37,604 37,604 0 147,533 147,533 BUILDING MATERIALS - 0.3% 0 703 703 Aaon, Inc. 0 21,027 21,027 0 5,425 5,425 Apogee Enterprises, Inc. 0 139,748 139,748 0 2,609 2,609 1Drew Industries, Inc. 0 90,741 90,741 0 251,516 251,516 CELLULAR COMMUNICATIONS - 0.0% 0 1,248 1,248 1USA Mobility, Inc. 0 29,790 29,790 CEMENT - 0.2% 0 3,610 3,610 1Astec Industries, Inc. 0 188,334 188,334 CLOTHING STORES - 1.0% 0 3,469 3,469 1Aeropostale, Inc. 0 132,100 132,100 0 3,490 3,490 Buckle, Inc. 0 121,975 121,975 0 2,845 2,845 1Dress Barn, Inc. 0 51,751 51,751 0 6,422 6,422 1Fossil, Inc. 0 164,082 164,082 0 4,297 4,297 1Gymboree Corp. 0 184,986 184,986 0 800 800 1Heelys, Inc. 0 17,520 17,520 0 2,569 2,569 1Jos A.

DESCRIPTION OF THE FUND Technology Fund, a portfolio of Federated Equity Funds, is registered under the Investment Company Act of 1940, as amended (the "Act), as an open-end, management investment company. The Fund consists of three classes of shares: Class A Shares, Class B Shares and Class C Shares. MDT Fund, a portfolio of Federated MDT Series, is registered under the Act as an open-end, management investment company. MDT Small Cap Growth Fund (the "Predecessor Fund") was reorganized into MDT Fund as of the close of business on December 8, 2006. Prior to the reorganization, MDT Fund had no investment operations. MDT Fund is the successor to the Predecessor Fund. For the purposes of these Pro Forma Financial Statements, the financial information covers the period from August 1, 2006 to July 31, 2007. MDT Fund consists of three classes of shares: Class A Shares, Class C Shares and Institutional Shares. Upon commencement of the combination with Technology Fund, MDT Fund will begin offering Class B Shares. NOTE 2. BASIS OF COMBINATION The accompanying unaudited Pro Forma Combining Portfolios of Investments, Statements of Assets and Liabilities and Statements of Operations (Pro Forma Financial Statements) reflect the accounts of Technology Fund and MDT Fund for the year ended July 31, 2007. These statements have been derived from the books and records utilized in calculating daily net asset values at July 31, 2007. The Pro Forma Financial Statements should be read in conjunction with the historical financial statements of Technology Fund and MDT Fund which have been incorporated by reference in the Statement of Additional Information. The Funds follow generally accepted accounting principles in the United States of America applicable to management investment companies which are disclosed in the historical financial statements. The Pro Forma Financial Statements give effect to the proposed exchange of assets of Class A Shares, Class B Shares and Class C Shares of Technology Fund for Class A Shares, Class B Shares and Class C Shares of MDT Fund. Under generally accepted accounting principles, MDT Fund will be the surviving entity for accounting purposes with its historical cost of investment securities and results of operations being carried forward. The Pro Forma Financial Statements have been adjusted to reflect the investment advisory fee arrangement for the surviving entity. Certain other operating costs have also been adjusted to reflect anticipated expenses of the combined entity. Other costs which may change as a result of the reorganization are currently undeterminable. For the year ended July 31, 2007, Technology Fund and MDT Fund paid investment advisory fees computed at the annual rate of 0.75% and 1.15%, respectively, as a percentage of average daily net assets. All costs with respect to the exchange will be borne by Federated Investors, Inc. and its affiliates. NOTE 3. PORTFOLIO VALUATION Market values of each Fund's portfolio securities are determined as follows: {circle}for equity securities, according to the last sale price or official closing price reported in the market in which they are primarily traded (either a national securities exchange or the over-the-counter market), if available; {circle}in the absence of recorded sales for equity securities, according to the mean between the last closing bid and asked prices; {circle}futures contracts and options are generally valued at market values established by the exchanges on which they are traded at the close of trading on such exchanges. Options traded in the over-the-counter market are generally valued according to the mean between the last bid and the last asked price for the option as provided by an investment dealer or other financial institution that deals in the option. The Board of Trustees (the "Trustees") may determine in good faith that another method of valuing such investments is necessary to appraise their fair market value; {circle}prices for total return swaps are based upon a valuation model determined by management incorporating underlying reference indexes, interest rates, yield curves and other market data or factors; prices for credit default swaps are furnished by an independent pricing service and are based upon a valuation model incorporating default probabilities, recovery rates and other market data or factors; prices for interest rate swaps are furnished by an independent pricing service and are based upon a valuation model incorporating interest rates, yield curves and other market data or factors; {circle}for mortgage-backed securities, based on the aggregate investment value of the projected cash flows to be generated by the security, as furnished by an independent pricing service; {circle}for investments in other open-end registered investment companies, based on net asset value (NAV); {circle}for other fixed-income securities, according to prices as furnished by an independent pricing service, except that fixed-income securities with remaining maturities of less than 60 days at the time of purchase are valued at amortized cost; and {circle}for all other securities at fair value as determined in accordance with procedures established by and under the general supervision of the Trustees. Prices for fixed-income securities furnished by a pricing service may be based on a valuation matrix which incorporates both dealer-supplied valuations and electronic data processing techniques. Such prices (other than prices of mortgage-backed securities) are generally intended to be indicative of the bid prices currently offered to institutional investors for the securities, except that prices for corporate fixed-income and asset-backed securities traded in the United States are generally intended to be indicative of the mean between such bid prices and asked prices. The Trustees have approved the use of such pricing services. A number of pricing services are available, and the Fund may use various pricing services or discontinue the use of any pricing service. Prices provided by independent pricing services may be determined without relying exclusively on quoted prices and may consider institutional trading in similar groups of securities, yield, quality, stability, risk, coupon rate, maturity, type of issue, trading characteristics, and other market data or factors. From time to time, when prices cannot be obtained from an independent pricing service, securities may be valued based on quotes from broker-dealers or other financial institutions that trade the securities. Trading in foreign securities may be completed at times which vary from the closing of the New York Stock Exchange (NYSE). In computing its NAV, the Fund values foreign securities using the latest closing price on the exchange on which they are traded immediately prior to the closing of the NYSE. Certain foreign currency exchange rates are generally determined at the latest rate prior to the closing of the NYSE. Foreign securities quoted in foreign currencies are translated into U.S. dollars at current rates. Events that affect these values and exchange rates may occur between the times at which they are determined and the closing of the NYSE. If such events materially affect the value of portfolio securities, these securities may be valued at their fair value as determined in good faith by the Trustees, although the actual calculation is done by others under the direction of Fund management. An event is considered material if there is both an affirmative expectation that the security's value will change in response to the event and a reasonable basis for quantifying the resulting change in value. NOTE 4. SHARES OF BENEFICIAL INTEREST The Pro Forma Class A Shares, Class B Shares and Class C Shares net asset value per share assumes the issuance of 1,595,279 Class A Shares, 2,566,363 Class B Shares and 506,064 Class C Shares, respectively, of MDT Fund in exchange for 3,338,219 Class A Shares, 5,727,796 Class B Shares and 1,106,944 Class C Shares of Technology Fund which would have been issued at July 31, 2007 in connection with the proposed reorganization. NOTE 5. FEDERAL INCOME TAXES Each fund has elected to be taxed as a "registered investment company" under the Internal Revenue Code. After the acquisition, MDT Fund intends to continue to qualify as a registered investment company, if such qualification is in the best interests of its shareholders, by complying with the Subchapter M provision of the Internal Revenue Code and to distribute to shareholders each year substantially all of its income. Accordingly, no provisions for federal income tax are necessary. The identified cost of investments for the Funds is substantially the same for both financial accounting and federal income tax purposes. The tax cost of investments will remain unchanged for the combined fund. NOTE 6. PROFORMA ADJUSTMENTS (a) Federated Equity Management Company of Pennsylvania, Technology Fund's investment adviser, receives for its services an annual investment advisory fee equal to 0.75% of the Funds average daily net assets. Federated MDTA LLC, MDT Fund's investment adviser (the "Adviser"), receives for its services an annual investment adviser fee equal to 1.15% of the Fund's average daily net assets. Prior to December 8, 2006, the Adviser received an annual investment adviser fee equal to 1.25% of the Fund's average daily net assets. Each investment adviser may voluntarily choose to waive any portion of its fee. The advisers can modify or terminate these voluntary waivers at any time. An adjustment to the combined investment adviser fee reflects the fee structure of MDT Fund on the average daily net assets of MDT Fund Pro Forma Combined. (b) Federated Administrative Services (FAS), under the Administrative Services Agreement (the "Agreement"), provides MDT Fund and Technology Fund with certain administrative personnel and services necessary to operate the funds. The fee paid to FAS is based on the average aggregate daily net assets of certain Federated funds. The administrative fee received during any fiscal year shall be at least $150,000 per portfolio and $40,000 per each additional class of Shares. An adjustment to the combined administrative personnel and services fee reflects the fee structure of MDT Fund on the average daily net assets of MDT Fund Pro Forma Combined. (c) Adjustment to reflect custodian fees resulting from higher trading activity and the combining of two portfolios into one. (d) Adjustment to reflect transfer and dividend disbursing agent fees and expenses resulting from the combining of two portfolios into one. (e) Adjustment to reflect directors'/trustees' fees resulting from higher average daily net assets and the combining of two portfolios into one. (f) Adjustment to reflect auditing fees resulting from the combining of two portfolios into one. (g) Adjustment to reflect legal fees resulting from the combining of two portfolios into one. (h) Adjustment to reflect portfolio accounting fees resulting from the combining of two portfolios into one. (i) Under a Distribution Plan (the "Plan") pursuant to Rule 12B-1 under the Act, MDT Fund may incur distribution expenses at 0.25% and 0.75% of the daily net assets of the Fund's Class A Shares and Class C Shares, respectively, to compensate Federated Securities Corp. (FSC), the principal distributor. Prior to the reorganization of the Fund on December 8, 2006, the Predecessor Fund incurred distribution expenses of 0.25% and 1.00% of the daily net assets of the Fund's Class A Shares and Class C Shares, respectively. Under a similar plan, Technology Fund may incur distribution expenses at 0.25% of Class A Shares and 0.75% of Class B Shares and Class C Shares average daily net assets. FSC may voluntarily choose to waive any portion of its fee.

Federated Investors Tower 1001 Liberty Avenue Pittsburgh, PA 15222-3779 ADMINISTRATOR Federated Administrative Services Federated Investors Tower 1001 Liberty Avenue Pittsburgh, PA 15222-3779 8 PART C. OTHER INFORMATION. ITEM 15. INDEMNIFICATION: Indemnification is provided to Trustees and officers of the Registrant pursuant to the Registrant's Declaration of Trust and Bylaws, except where such indemnification is not permitted by law. However, the Declaration of Trust and Bylaws do not protect the Trustees or officers from liability based on willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of their office. Trustees and officers of the Registrant are insured against certain liabilities, including liabilities arising under the Securities Act of 1933 (the "Act"). Insofar as indemnification for liabilities arising under the Act may be permitted to Trustees, officers, and controlling persons of the Registrant by the Registrant pursuant to the Declaration of Trust or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by Trustees, officers, or controlling persons of the Registrant in connection with the successful defense of any act, suit, or proceeding) is asserted by such Trustees, officers, or controlling persons in connection with the shares being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. Insofar as indemnification for liabilities may be permitted pursuant to Section 17 of the Investment Company Act of 1940 for Trustees, officers, or controlling persons of the Registrant by the Registrant pursuant to the Declaration of Trust or otherwise, the Registrant is aware of the position of the Securities and Exchange Commission as set forth in Investment Company Act Release No. IC-11330. Therefore, the Registrant undertakes that in addition to complying with the applicable provisions of the Declaration of Trust or otherwise, in the absence of a final decision on the merits by a court or other body before which the proceeding was brought, that an indemnification payment will not be made unless in the absence of such a decision, a reasonable determination based upon factual review has been made (i) by a majority vote of a quorum of non-party Trustees who are not interested persons of the Registrant or (ii) by independent legal counsel in a written opinion that the indemnitee was not liable for an act of willful misfeasance, bad faith, gross negligence, or reckless disregard of duties. The Registrant further undertakes that advancement of expenses incurred in the defense of a proceeding (upon undertaking for repayment unless it is ultimately determined that indemnification is appropriate) against an officer, Trustee, or controlling person of the Registrant will not be made absent the fulfillment of at least one of the following conditions: (i) the indemnitee provides security for his undertaking; (ii) the Registrant is insured against losses arising by reason of any lawful advances; or (iii) a majority of a quorum of disinterested non-party Trustees or independent legal counsel in a written opinion makes a factual determination that there is reason to believe the indemnitee will be entitled to indemnification.
