 FEDERATED TECHNOLOGY FUND, A PORTFOLIO OF FEDERATED EQUITY FUNDS


PROXY STATEMENT - PLEASE VOTE!

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?

person at the meeting, or by completing and returning the enclosed proxy card.

shares today.  If approved, the Reorganization will take place automatically.

                         Telephone No:  1-800-341-7400

      This Prospectus/Proxy Statement describes  the  proposal whereby Federated
Technology Fund ("Technology Fund"), a portfolio of Federated  Equity Funds (the
"Trust"),  would  transfer all of its assets to Federated MDT Small  Cap  Growth
Fund ("MDT Fund"),  a  portfolio  of  Federated  MDT Series (the "MDT Trust") in
exchange for Class A Shares, Class B Shares and Class  C Shares of MDT Fund (the
"Reorganization"). 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."

      The investment adviser  for Technology Fund is Federated Equity Management
Company of Pennsylvania (the "Technology  Adviser")  and  the investment adviser
for  MDT  Fund is Federated MDTA LLC (the "MDT Adviser"). This  Prospectus/Proxy
Statement should  be  retained for future reference. It sets forth concisely the
information about the Funds  that  a  prospective  investor  should  know before
investing.   This  Prospectus/Proxy Statement is accompanied by the Prospectuses

December 17, 2007  for  Class B Shares, as well as an SAI dated January 23, 2008
relating  to  this  Prospectus/Proxy   Statement,   all   containing  additional

   This summary is qualified in its entirety by reference to the additional
   information contained elsewhere in this Prospectus/Proxy Statement, or
   incorporated by reference into this Prospectus/Proxy Statement.  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.

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.

1    With respect to Technology Fund, the percentages shown are based on expenses for the entire fiscal year ended October 31, 2006.
  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.

  reductions)
2   The Adviser for Technology Fund voluntarily waived/reimbursed a portion of the management fee.  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.  Pursuant to this contractual commitment, the Adviser of MDT Fund Pro Forma Combined expects to waive a
  portion of its management fee 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.  Also includes a recordkeeping fee which is used to
  compensate intermediaries for record keeping services.  The administrator voluntarily waived a portion of its fee.  Additionally,
  the shareholder services provider did not charge, and therefore the Fund did not accrue, a portion of its fee.  The administrator
  and shareholder services provider can terminate this voluntary waiver and/or reduction at any time.  Total other expenses paid by
  Technology Fund's Class A Shares (after the voluntary waiver and reduction) were 1.33% for the fiscal year ended October 31, 2006.
6   With respect to MDT Fund and MDT Fund Pro Forma Combined, this includes a shareholder services/account administration fee which
  is used to compensate intermediaries for shareholder services or account administrative services. Also includes a recordkeeping
  fee which is used to compensate intermediaries for recordkeeping services. With respect to MDT Fund, pursuant to its contractual
  commitment, the Adviser expects to reimburse 1.07% of certain operating expenses of the Fund.  Additionally, although not
  contractually obligated to do so, the Adviser expects to voluntarily reimburse certain operating expenses of the Fund.  This
  voluntary reimbursement can be terminated at any time.  For both MDT Fund and MDT Fund Pro Forma Combined, the administrator
  expects to voluntarily waive a portion of its fee.  This voluntary waiver can be terminated at any time. Total other expenses paid
  by MDT Fund's Class A Shares and MDT Fund Pro Forma Combined's Class A Shares (after the anticipated voluntary waiver and
  reimbursement) are expected to be 1.75% and 1.65%, respectively, for the fiscal year ending July 31, 2008.
7   The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total operating
  expenses (including distribution (12b-1) fees) paid by MDT Fund Class A Shares and MDT Fund Pro Forma Combined Class A Shares
  (after the voluntary waivers and reimbursements) will not exceed 1.75% for the fiscal year ending July 31, 2008.  Although these
  actions are voluntary, the Adviser and its affiliates have agreed not to terminate these waivers or reimbursements until after
  September 30, 2008.



  EXAMPLE

  This example is intended to help you compare the cost of investing in the
  indicated Funds with the cost of investing in other mutual funds.

  The Example assumes that you invest $10,000 in each respective Fund for the
  time periods indicated and then redeem all of your shares at the end of those
  periods.  The Example also assumes that your investment has a 5% return each
  year and that the operating expenses of Technology Fund are before voluntary
  waivers, reimbursements and reductions as shown in the Table and remain the
  same.  For MDT Fund and MDT Fund Pro Forma Combined, the one-year dollar
  amount and the dollar amounts for the first year of the 3, 5 and 10 Years
  columns reflect the contractually imposed expense limitation of 2.05% for
  Class A Shares.  The second year of the 3, 5, and 10 Years columns reflects
  the contractually imposed expense limitation of 2.05% for four months and the
  "Total Annual Fund Operating Expenses" of Class A Shares without any waivers,
  reimbursements or reductions for the remainder of the year.  The third and
  later years within the 5 and 10 Years columns reflect the "Total Annual Fund
  Operating Expenses" of the Class A Shares without any waivers, reimbursements
  or reductions.  Although your actual costs and returns may be higher or lower,
  based on these assumptions your costs would be:

1    With respect to Technology Fund, the percentages shown are based on expenses for the entire fiscal year ended October 31, 2006.
  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 period 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.  These waivers and reimbursements are shown below along with the
  net expenses the Fund expects to pay for the fiscal period ending July 31, 2008.
  Total Waivers, Reimbursements and Reductions of Fund Expenses (voluntary)                             0.37%     2.81%    1.12%
  Total Actual/Anticipated Annual Fund Operating Expenses (after waivers, reimbursements and            2.77%     2.50%    2.50%
  reductions)
2   The Adviser for Technology Fund voluntarily waived/reimbursed a portion of the management fee.  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 other Share
  classes of the Fund.  Any waivers by the administrator 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.  Pursuant to this contractual commitment, the Adviser of MDT Fund
  Pro Forma Combined expects to waive a portion of its management fee 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 Technology Fund, this includes a shareholder services/account administration fee which is used to compensate
  intermediaries for shareholder services or account administrative services.  Also includes a recordkeeping fee which is used to
  compensate intermediaries for record keeping services.  The administrator voluntarily waived a portion of its fee.  Additionally,
  the shareholder services provider did not charge, and therefore the Fund did not accrue, a portion of its fee.  The administrator
  and shareholder services provider can terminate this voluntary waiver and/or reduction at any time.  Total other expenses paid by
  Technology Fund's Class B Shares (after the voluntary waiver and reduction) were 1.58% for the fiscal year ended October 31, 2006.
5   With respect to MDT Fund and MDT Fund Pro Forma Combined, this includes a shareholder services/account administration fee which
  is used to compensate intermediaries for shareholder services or account administrative services. Also includes a recordkeeping
  fee which is used to compensate intermediaries for recordkeeping services. With respect to MDT Fund, pursuant to its contractual
  commitment, the Adviser expects to reimburse 1.07% of certain operating expenses of the Fund.  Additionally, although not
  contractually obligated to do so, the Adviser expects to voluntarily reimburse certain operating expenses of the Fund.  This
  voluntary reimbursement can be terminated at any time.  For both MDT Fund and MDT Fund Pro Forma Combined, the administrator
  expects to voluntarily waive a portion of its fee.  This voluntary waiver can be terminated at any time. Total other expenses paid
  by MDT Fund's Class B Shares and MDT Fund Pro Forma Combined's Class B Shares (after the anticipated voluntary waiver and
  reimbursement) are expected to be 1.75% and 1.65%, respectively, for the fiscal year ending July 31, 2008.
6  After Class B Shares have been held for eight years from the date of purchase, they will automatically convert to Class A Shares
  on or about the last day of the following month.  Class A Shares pay lower operating expenses than Class B Shares.

  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 4), the Adviser and
  administrator expect to waive and/or reimburse certain amounts.  These waivers and reimbursements are shown below along with the
  net expenses the Fund expects to pay for the fiscal year ending July 31, 2008.
  Total Waivers, Reimbursements and Reductions of Fund Expenses (voluntary)                             0.39%     0.30%    0.30%
  Total Actual/Anticipated Annual Fund Operating Expenses (after waivers, reimbursements and            2.75%     2.50%    2.50%
  reductions)
3   The Adviser for Technology Fund voluntarily waived/reimbursed a portion of the management fee.  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.
4   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 C Shares to not more than 2.80% of its daily net assets.  Any waivers by the administrator 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.  Pursuant to this
  contractual commitment, the Adviser of MDT Fund Pro Forma Combined expects to waive a portion of its management fee 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.
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.  Also includes a recordkeeping fee which is used to
  compensate intermediaries for record keeping services.  The administrator voluntarily waived a portion of its fee.  Additionally,
  the shareholder services provider did not charge, and therefore the Fund did not accrue, a portion of its fee.  The administrator
  and shareholder services provider can terminate this voluntary waiver and/or reduction at any time.  Total other expenses paid by
  Technology Fund's Class C Shares (after the voluntary waiver and reduction) were 1.56% for the fiscal year ended October 31, 2006.
6   With respect to MDT Fund and MDT Fund Pro Forma Combined, this includes a shareholder services/account administration fee which
  is used to compensate intermediaries for shareholder services or account administrative services. Also includes a recordkeeping
  fee which is used to compensate intermediaries for recordkeeping services. With respect to MDT Fund, pursuant to its contractual
  commitment, the Adviser expects to reimburse 1.07% of certain operating expenses of the Fund.  Additionally, although not
  contractually obligated to do so, the Adviser expects to voluntarily reimburse certain operating expenses of the Fund.  This
  voluntary reimbursement can be terminated at any time.  For both MDT Fund and MDT Fund Pro Forma Combined, the administrator
  expects to voluntarily waive a portion of its fee.  This voluntary waiver can be terminated any time. Total other expenses paid by
  MDT Fund's Class C Shares and MDT Fund Pro Forma Combined's Class C Shares (after the anticipated voluntary waiver and
  reimbursement) are expected to be 1.75% and 1.65%, respectively, for the fiscal year ending July 31, 2008.
7   The Adviser and its affiliates have voluntarily agreed to waive their fees and/or reimburse expenses so that the total operating
  expenses (including distribution (12b-1) fees) paid by MDT Fund Class C Shares and MDT Fund Pro Forma Combined Class C Shares
  (after the voluntary waivers and reimbursements) will not exceed 2.50% for the fiscal year ending July 31, 2008.  Although these
  actions are voluntary, the Adviser and its affiliates have agreed not to terminate these waivers or reimbursements until after
  September 30, 2008.


  EXAMPLE

  This example is intended to help you compare the cost of investing in the
  indicated Funds with the cost of investing in other mutual funds.

  The Example assumes that you invest $10,000 in each respective Fund for the
  time periods indicated and then redeem all of your shares at the end of those
  periods.  The Example also assumes that your investment has a 5% return each
  year and that the operating expenses of Technology Fund are before voluntary
  waivers, reimbursements and reductions as shown in the Table and remain the
  same.  For MDT Fund and MDT Fund Pro Forma Combined, the one-year dollar
  amount and the dollar amounts for the first year of the 3, 5 and 10 Years
  columns reflect the contractually imposed expense limitation of 2.80% for
  Class C Shares.  The second year of the 3, 5, and 10 Years columns reflects
  the contractually imposed expense limitation of 2.80% for four months and the
  "Total Annual Fund Operating Expenses" of Class C Shares without any waivers,
  reimbursements or reductions for the remainder of the year.  The third and
  later years within the 5 and 10 Years columns reflect the "Total Annual Fund
  Operating Expenses" of the Class C Shares without any waivers, reimbursements
  or reductions.  Although your actual costs and returns may be higher or lower,
  based on these assumptions your costs would be:

COMPARISON OF POTENTIAL RISKS AND REWARDS: PERFORMANCE INFORMATION


TECHNOLOGY FUND


RISK/RETURN BAR CHART AND TABLE
The performance information shown below will help you analyze the Fund's
investment risks in light of its historical returns. The bar chart shows the
variability of the Fund's Class A Shares total returns on a calendar year-by-
year basis. The Average Annual Total Return table shows returns averaged over
the stated periods, and includes comparative performance information. The Fund's
performance will fluctuate, and past performance (before and after taxes) is no
guarantee of future results.

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). ITS LOWEST QUARTERLY
RETURN WAS (39.32)% (QUARTER ENDED DECEMBER 31, 2000).
AVERAGE ANNUAL TOTAL RETURN TABLE
The Average Annual Total Returns for the Fund's Class A Shares, Class B Shares
and Class C Shares are reduced to reflect applicable sales charges.  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.

   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. The
      stated returns assume the highest historical FEDERAL income and capital
      gains tax rates. Return After Taxes on Distributions assumes a continued
      investment in the Fund and shows the effect of taxes on Fund
      distributions. Return After Taxes on Distributions and Sale of Fund Shares
      assumes all Shares were redeemed at the end of each measurement period,
      and shows the effect of any taxable gain (or offsetting loss) on
      redemption, as well as the effects of taxes on Fund distributions. These
      after-tax returns do NOT reflect the effect of any applicable STATE and
      LOCAL taxes. After-tax returns for Class B Shares and Class C Shares will
      differ from those shown above for Class A Shares.  After-tax returns are
      not relevant to investors holding Shares through tax-deferred programs,
      such as IRA or 401(k) plans.
   3  The returns shown for Class C Shares include the effect of a 1.00% front-
      end sales charge on Class C Shares purchased on or before January 31,
      2007.  Effective February 1, 2007, this front-end sales charge was
      eliminated.
   4  The NCI is an unmanaged index that measures all NASDAQ domestic and non-
      U.S. based common stocks listed on the NASDAQ Stock Market. The MLT 100 is
      an unmanaged, equal dollar weighted index of 100 stocks designed to
      measure the performance of a cross section of large, actively traded
      technology stocks and ADRs, The index was developed with a base value of
      200 as of January 30, 1998.
   5  Lipper figures represent the average of the total returns reported by all
      of the mutual funds designated by Lipper, Inc. as falling into the
      category indicated. These figures do not reflect sales charges.

MDT FUND


                {capital-tau}RISK/RETURN BAR CHART AND TABLE CLASS A SHARES
The Fund is the successor to MDT Small Cap Growth Fund pursuant to a
reorganization that was completed on the close of business on December 8, 2006.
Prior to that date, the Fund had no investment operations. Accordingly, the
performance information and financial information provided in this prospectus
for periods prior to December 11, 2006, is historical information for MDT Small
Cap Growth Fund. MDT Small Cap Growth Fund was managed by MDT Advisers and had
similar investment objectives and strategies as the Fund.

 The performance information shown below will help you analyze the Fund's
investment risks in light of its historical returns. The bar chart shows the
variability of the Fund's Class A Shares total return on a calendar year-by-year
basis. The Average Annual Total Return table shows returns averaged over the
stated periods, and includes comparative performance information. The Fund's
performance will fluctuate, and past performance (before and after taxes) is no
guarantee of future results.

The "y" axis reflects the "% Total Return" beginning with "0%" and increasing in
increments of 2% up to 10%.



The "x" axis represents calculation periods from the earliest first full
calendar year end of the MDT Fund's Start of Performance through the calendar
year ended 2006.  The light gray shaded chart features one distinct vertical
bar, shaded in black, and each visually representing by height the total return
percentage for the calendar year.   The calculated total return percentage for
the MDT Fund is stated at the top of the respective bar for the calendar year
ended 2006.  The percentage notes is 9.45%.



THE TOTAL RETURN SHOWN IN THE BAR CHART DOES NOT REFLECT THE PAYMENT OF ANY
SALES CHARGES OR RECURRING SHAREHOLDER ACCOUNT FEES. IF THESE CHARGES OR FEES
HAD BEEN INCLUDED, THE RETURN SHOWN WOULD HAVE BEEN LOWER.
THE FUND'S CLASS A SHARES TOTAL RETURN FOR THE SIX-MONTH PERIOD FROM JANUARY 1,
2007 TO JUNE 30, 2007 WAS 17.09%.
WITHIN THE PERIOD SHOWN IN THE BAR CHART, THE FUND'S CLASS A SHARES HIGHEST
QUARTERLY RETURN WAS 15.91% (QUARTER ENDED MARCH 31, 2006). ITS LOWEST QUARTERLY
RETURN WAS (7.62)% (QUARTER ENDED SEPTEMBER 30, 2006).

                {capital-tau}AVERAGE ANNUAL TOTAL RETURN TABLE
The Average Annual Total Returns for the Fund's Class A Shares are reduced to
reflect all applicable sales charges. 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 Russell
2000{reg-trade-mark} Growth Index and the Lipper Small-Cap Growth Funds Index.
Returns of the Russell 2000{reg-trade-mark} Growth Index do not reflect taxes,
sales charges, expenses or other fees that the SEC requires to be reflected in
the Fund's performance. The Russell 2000{reg-trade-mark} Growth Index is
unmanaged and, unlike the Fund, is not affected by cash flows. It is not

1 The start of performance date for the Fund's Class A Shares and Class C Shares
  was September 15, 2005.
2 After-tax returns are calculated using a standard set of assumptions. The
  stated returns assume the highest historical FEDERAL income and capital gains
  tax rates. Return After Taxes on Distributions assumes a continued investment
  in the Fund and shows the effect of taxes on Fund distributions. Return After
  Taxes on Distributions and Sale of Fund Shares assumes all shares were
  redeemed at the end of each measurement period, and shows the effect of any
  taxable gain (or offsetting loss) on redemption, as well as the effects of
  taxes on Fund distributions. These after-tax returns do NOT reflect the effect
  of any applicable STATE and LOCAL taxes. After-tax returns are not relevant to
  investors holding Shares through tax-deferred programs, such as IRA or 401(k)
  plans.
3 Historical returns do not include the effect of a 1.00% front-end sales charge
  on Class C Shares purchased prior to February 1, 2007. Effective February 1,
  2007, this sales charge was eliminated.
4 The Russell 2000{reg-trade-mark} Growth Index measures the performance of
  those Russell 2000 companies with higher price-to-book ratios and higher
  forecasted growth values.
5 The Lipper Small-Cap Growth Funds Index is an average of funds that, by
  portfolio practice, invest at least 75% of their equity assets in companies
  with market capitalizations (on a three-year weighted basis) less than 250% of
  the dollar-weighted median of the smallest 500 of the middle 1,000 securities
  of the S&P SuperComposite 1500 Index. Small-cap growth funds typically have an
  average price-to-earnings ratio, price-to-book ratio, and three-year sales-
  per-share growth value, compared to the S&P SmallCap 600 Index.

 The Financial Highlights will help you understand the Fund's financial
performance for its past five fiscal years. Some of the information is presented
on a per Share basis. Total returns represent the rate an investor would have
earned (or lost) on an investment in the Fund, assuming reinvestment of any
dividends and capital gains.

 This information for the fiscal year ended October 31, 2006 has been audited by
KPMG LLP, an independent registered public accounting firm, whose report, along
with the Fund's audited financial statements, is included in the Annual Report.
As discussed in the Annual Report, the information for prior years was audited
by Deloitte & Touche LLP, another independent registered public accounting firm.

 On August 18, 2006, the Fund's Board, upon recommendation of the Audit
Committee, appointed KPMG LLP as the Fund's independent registered public
accounting firm for the fiscal year ending October 31, 2006. On the same date,
the Fund's former auditor, Deloitte & Touche LLP resigned. See the Fund's Annual

ADVISORY FEES, SERVICE FEES, SHAREHOLDER FEES AND OTHER EXPENSES





INVESTMENT ADVISORY FEES

       The annual investment advisory fee for Technology Fund is 0.75% of
Technology Fund's average daily net assets.  Technology Adviser may voluntarily
choose to waive a portion of its advisory fee or reimburse other expenses of
Technology Fund.  This voluntary waiver or reimbursement may be terminated by
Technology Adviser at any time in its sole discretion.

       The annual investment advisory fee for MDT Fund is 1.15% of MDT Fund's
average daily net assets.  Under the investment advisory contract, which is
subject to annual renewal by the Board of Trustees of Federated MDT Series, MDT
Adviser will waive the amount, limited to the amount of the advisory fee, by
which MDT Fund's aggregate annual operating expenses, including the investment
advisory fee but excluding interest, taxes, brokerage commissions, expenses of
registering or qualifying MDT Fund and its shares under federal and state laws
and regulations, expenses of withholding taxes, and extraordinary expenses
exceed 2.05% for Class A Shares and 2.80% for Class C Shares of its average
daily net assets.  MDT Adviser has agreed to keep these contractual limitations
in place through December 8, 2008.  The advisory fee for MDT Fund's Class B
Shares is not subject to a contractual expense cap, but to the extent the
advisory fee is reduced due to the expense caps for the other classes, the
reduction would also apply to Class B Shares.  In addition, MDT Adviser may
voluntarily choose to waive a portion of its advisory fee or reimburse other
expenses of MDT Fund.  This voluntary waiver or reimbursement may be terminated
by MDT Adviser at any time in its sole discretion.

      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:

      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.

issued,  transferable  without  restriction  and  will  have  no  preemptive  or
conversion  rights.  Reference is hereby made to the Prospectuses  of  MDT  Fund

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.

SHAREHOLDERS Massachusetts that expressly disclaim the liability  of  its  shareholders for acts or obligations of the
             Trust.

             In the unlikely event a shareholder is held personally liable for  the  Trust's obligations, the Trust is
             required  by the Declaration of Trust to use its property to protect or compensate  the  shareholder.  On
             request, the  Trust  will defend any claim made and pay any judgment against a shareholder for any act or
             obligation of the Trust.   Therefore, financial loss resulting from liability as a shareholder will occur

             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.

    THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS APPROVE THE
                       AGREEMENT AND PLAN OF REORGANIZATION.


              ABOUT THE PROXY SOLICITATION AND THE SPECIAL MEETING

       Proxies are being solicited by the Board of the  Trust  on  behalf of its
portfolio, Technology Fund.  The proxies will be voted at the special meeting of
shareholders  of  Technology  Fund  to  be  held at 2:00 p.m. (Eastern Time)  on
February 29, 2008, at 5800 Corporate Drive, Pittsburgh,  Pennsylvania 15237-7000
(such special meeting and any adjournment or postponement  thereof  are referred
to as the "Special Meeting").

      The cost of the solicitation, including the printing and mailing  of proxy
materials,  will  be  borne  by  MDT  Adviser or its affiliates.  In addition to
solicitations  through  the  mails,  proxies   may  be  solicited  by  officers,
employees,  and  agents of MDT Adviser or its affiliates  or,  if  necessary,  a
communications firm  retained  for  this  purpose.  Such solicitations may be by
telephone, through Internet or otherwise.   Any  telephonic  solicitations  will
follow  procedures  designed  to  ensure  accuracy  and prevent fraud, including
requiring  identifying  shareholder  information,  recording  the  shareholder's
instructions, and confirming to the shareholder after  the  fact.   Shareholders
who communicate proxies by telephone or by other electronic means have  the same
power  and  authority  to  issue,  revoke,  or  otherwise  change  their  voting
instructions as shareholders submitting proxies in written form.  The Trust  may
reimburse  custodians,  nominees,  and  fiduciaries  for  the  reasonable  costs
incurred  by  them  in  connection with forwarding solicitation materials to the
beneficial owners of shares held of record by such persons.

      The purpose of the  Special  Meeting  is  set  forth  in  the accompanying
Notice.   The Board of the Trust knows of no business other than that  mentioned
in the Notice  that  will be presented for consideration at the Special Meeting.
Should other business  properly  be  brought before the Special Meeting, proxies
will be voted in accordance with the best  judgment  of  the  persons  named  as
proxies.   This  Prospectus/Proxy  Statement  and  the  enclosed  proxy card are
expected to be mailed on or about January 23, 20087, to shareholders  of  record
at the close of business on January 2, 2008 (the "Record Date").

      Technology   Fund's   Annual  Report,  which  includes  audited  financial
statements for its fiscal year  ended  October  31,  2007,  and  its Semi-Annual
Report containing unaudited financial statements for the six-month  period ended
April 30, 2007, were previously mailed to shareholders of Technology  Fund.  MDT
Fund's Annual Report, which includes audited financial statements for its fiscal
year ended July 31, 2007, was previously mailed to shareholders of MDT Fund.

      Technology  Fund  and  MDT Fund will promptly provide, without charge  and
upon  request,  to  each  person to  whom  this  Prospectus/Proxy  Statement  is
delivered, a copy of its Annual  Report  and/or  its  Semi-Annual Report (in the
case of Technology Fund).  Requests for Annual Reports  or  Semi-Annual  Reports
for  Technology  Fund or MDT Fund may be made by writing to the Fund's principal
executive offices  or by calling the toll-free telephone number, 1-800-341-7400.
The principal executive  office for both Funds is located at Federated Investors
Funds, 5800 Corporate Drive,  Pittsburgh,  Pennsylvania 15237-7000.  The reports
are    also    available    electronically    at    Federated's    website    at
FederatedInvestors.com.


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 purposes  of  determining  a  quorum  for  transacting business at the
Special  Meeting,  abstentions  and broker "non-votes" (that  is,  proxies  from
brokers or nominees indicating that  such persons have not received instructions
from  the  beneficial  owner or other persons  entitled  to  vote  shares  on  a
particular matter with respect  to  which  the  brokers  or nominees do not have
discretionary power) will be treated as shares that are present  but  which have
not been voted.  For this reason, abstentions and broker non-votes will have the
effect  of a "no" vote for purposes of obtaining the requisite approval  of  the
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.

         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.

            MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE OF MDT FUND


Management's Discussion of Fund Performance

The fund's total return for the fiscal year ended July 31, 2007 was 22.29% for
Class A Shares, and 21.39% for Class C Shares.1 The total return of the Russell
2000{reg-trade-mark} Growth Index was 16.83% for the same period.2 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 Russell
2000{reg-trade-mark} Growth Index. The total return of the Lipper Small-Cap
Growth Funds Index was 19.51% for the same period.3
MARKET OVERVIEW

Over the twelve month reporting period ended July 31, 2007, domestic equity
markets enjoyed a positive, if somewhat rocky, performance highlighted by a
sudden decline in late February and another decline as the reporting period
ended in July. 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. Growth stocks outperformed value stocks by a wide margin during
the year with the Russell 3000{reg-trade-mark} Growth Index7 returning 19.24% as
compared to 12.97% for the Russell 3000{reg-trade-mark} Value Index.8
1 The fund is the successor to MDT Small Cap Growth Fund pursuant to a
reorganization that took place on December 8, 2006. Prior to that date, the fund
had no investment operations. Accordingly, the performance information provided
is historical information of MDT Small Cap Growth Fund. Small company stocks may
be less liquid and subject to greater price volatility than large capitalization
stocks.
2 The Russell 2000{reg-trade-mark} Growth Index measures the performance of
those Russell 2000 companies with higher price-to-book ratios and higher
forecasted growth values. The index is unmanaged and investments can not be made
directly in an index.
3 The Lipper Small-Cap Growth Funds Index is an average of funds that, by
portfolio practice, invest at least 75% of their equity assets in companies with
market capitalizations (on a three-year weighted basis) less than 250% of the
dollar-weighted median of the smallest 500 of the middle 1,000 securities of the
S&P SuperComposite 1500 Index. Small-cap growth funds typically have an average
price-to-earnings ratio, price-to-book ratio, and three-year sales-per-share
growth value, compared to the S&P SmallCap 600 Index.
4 The Russell Midcap{reg-trade-mark} Index measures the performance of the 800
smallest companies in the Russell 1000{reg-trade-mark} Index, which represent
approximately 31% of the total market capitalization of the Russell
1000{reg-trade-mark} Index. The index is unmanaged and investments can not be
made directly in an index.
5 Russell Top 200{reg-trade-mark} Index measures the performance of the 200
largest companies in the Russell 1000{reg-trade-mark} Index, which represents
approximately 69% of the total market capitalization of the Russell
1000{reg-trade-mark} Index. The index is unmanaged and investments can not be
made directly in an index.
6 The Russell 2000{reg-trade-mark} Index measures the performance of the 2,000
smallest companies in the Russell 3000{reg-trade-mark} Index, which represents
approximately 10% of the total market capitalization of the Russell
3000{reg-trade-mark} Index. The index is unmanaged and investments can not be
made directly in an index.
7 The Russell 3000{reg-trade-mark} Growth Index measures the performance of
those Russell 3000{reg-trade-mark} Index companies with higher price-to-book
ratios and higher forecasted growth values. The stocks in this index are also
members of either the Russell 1000{reg-trade-mark} Growth or the Russell
2000{reg-trade-mark} Growth indexes. The index is unmanaged and investments can
not be made directly in an index.
8 The Russell 3000{reg-trade-mark} Value Index measures the performance of those
Russell 3000{reg-trade-mark} Index companies with lower price-to-book ratios and
lower forecasted growth values. The stocks in this index are also members of
either the Russell 1000{reg-trade-mark} Value or the Russell
2000{reg-trade-mark} Value indexes. The index is unmanaged and investments can
not be made directly in an index.
PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE WHICH IS NO GUARANTEE OF
FUTURE RESULTS. INVESTMENT RETURN AND PRINCIPAL VALUE WILL FLUCTUATE SO THAT AN
INVESTOR'S SHARES, WHEN REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL
COST. MUTUAL FUND PERFORMANCE CHANGES OVER TIME AND CURRENT PERFORMANCE MAY BE

The best performing sectors during the reporting period in the Russell
3000{reg-trade-mark} Index were Materials (up 35.67%), Telecommunication
Services (up 30.35%) and Information Technology (up 29.43%). Underperforming
sectors included Financials (up just 2.11%, negatively influenced by a
disruption in credit markets late in the reporting period), Health Care (up
8.23%) and Consumer Staples (up 11.12%).
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.
Individual stocks detracting from the fund's performance relative to the Russell
2000{reg-trade-mark} Growth Index included: HANSEN NATIONAL CORP., AQUANTIVE
INC., EGL INC., DAKTRONICS INC., and LOGITECH INTERNATIONAL.

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.

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.  For  the  period  from the
Reorganization  through  July  31,  2007,  MDT Fund did not charge or accrue the
distribution  12b-1 fee for the Class A Shares.     Adjustment  to  reflect  the
expense structure  of  MDT  Fund on the average daily net assets of MDT Fund Pro
Forma Combined.

(j) Effective December 11, 2006,  under  the  terms  of  a  Shareholder Services
Agreement, MDT Fund may pay fees up to 0.25% of the average daily  net assets of
the Fund's Class A Shares and Class C Shares to financial intermediaries  or  to
Federated Shareholder Services Company (FSSC).  Prior to the reorganization, the
Predecessor  Fund  did  not  incur  a shareholder services fee.  Under a similar
plan, Technology Fund may pay fees up  to  0.25% of the average daily net assets
of Class A Shares, Class B Shares and Class C Shares to financial intermediaries
or to FSSC.  FSSC or these financial intermediaries  may  voluntarily  choose to
reimburse  any  portion  of  their  fee.    Adjustment  to  reflect  the expense
structure  of  MDT  Fund  on the average daily net assets of MDT Fund Pro  Forma
Combined.

(k) Adjustment to reflect share  registration costs resulting from the combining
of two portfolios into one.

(l)  Adjustment to reflect printing  and  postage  expense  resulting  from  the
combining of two portfolios into one.

(m)   Adjustment  to  reflect insurance premiums resulting from the combining of
two portfolios into one.

(n)  Adjustment to reflect  miscellaneous  expenses resulting from the combining
of two portfolios into one.

(o)  Under the investment advisory contract,  Federated MDTA LLC (the "Adviser")
is  contractually obligated to waive, to the extent  of  its  adviser  fee,  the
amount,  if  any,  in  order  to  limit  the aggregate annual operating expenses
(excluding interest, taxes and brokerage commissions)  for  MDT  Fund's  Class A
Shares,  Class  C  Shares and Institutional Shares to not more than 2.05%, 2.80%
and 1.80%, respectively, of average daily net assets.  The Adviser has agreed to
keep these contractual  limitations  in  place  through  December  8, 2008.  The
Adviser  may  also  voluntarily  choose  to  waive  a  portion of its fee and/or
reimburse  certain operating expenses of MDT Fund.  The Adviser  can  modify  or
terminate this  voluntary  waiver  and/or  reimbursement at any time at its sole
discretion.   An adjustment to the combined waiver/reimbursement  of  investment
adviser fee reflects  the  fee  structure  of  MDT Fund on the average daily net
assets of MDT Fund Pro Forma Combined.

(p)  Effective July 15, 2006, FAS contractually agreed to waive a portion of its
fee which it would otherwise be entitled to receive  from  MDT  Fund  under  the
Agreement.  The level of fees payable by MDT Fund to FAS for the period will not
exceed the level of fees which MDT Fund would have paid during the period to its
previous  service provider under its previous administrative services agreement.
In addition, FAS may voluntarily choose to waive any portion of its fee. FAS can
modify or terminate  this  voluntary  waiver at any time at its sole discretion.
An adjustment to the combined waiver of  administrative  personnel  and services
fee  reflects  the fee structure of MDT Fund on the average daily net assets  of
MDT Fund Pro Forma Combined.

(q) An adjustment  to  the  combined  reimbursement  of other operating expenses
reflects the fee structure of MDT Fund on the average  daily  net  assets of MDT
Fund Pro Forma Combined.

(r)  Technology  Fund directs portfolio trades to a broker that in turn  pays  a
portion of Technology Fund's operating expenses.  MDT Fund does not utilize this
type of brokerage  arrangement.   Adjustment  to  reflect reduction of fees paid
indirectly from directed brokerage arrangements.

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.

ITEM 17.    UNDERTAKINGS


      (1)   The undersigned Registrant agrees that prior to any public
reoffering of the securities registered through the use of a prospectus which is
a part of this Registration Statement by any person or party who is deemed to be
an underwriter within the meaning of Rule 145(c) of the Securities Act of 1933,
the reoffering prospectus will contain the information called for by the
applicable registration form for reofferings by persons who may be deemed
underwriters, in addition to the information called for by the other items of
the applicable form.


      (2)   The undersigned Registrant agrees that every prospectus that is
filed under paragraph (1) above will be filed as a part of an amendment to the
Registration Statement and will not be used until the amendment is effective,
and that, in determining any liability under the Securities Act of 1933, each
