          Q&A FOR THE MANAGED ALLOCATION FUNDS PROPOSED MERGERS INTO
                          FEDERATED MDT BALANCED FUND
                            FINAL -SEPTEMBER 4, 2007
                          FOR FEDERATED INTERNAL USE ONLY


The Board of Trustees of Federated Managed Allocation Portfolio's approved the
merger of Federated Conservative Allocation Fund (FCOAF), Federated Moderate
Allocation Fund (FMAF) and Federated Growth Allocation Fund (FGAF) into
Federated MDT Balanced Fund at their May 2007 meeting.  Each merger is
contingent upon the approval of the shareholders of the applicable Managed
Allocation Fund. Proxy statements are scheduled to be mailed to shareholders by
September 7, 2007 with the shareholder meeting scheduled for October 19, 2007.
The mergers are scheduled to occur on October 26, 2007.

QUESTION AND ANSWER:
WHY ARE THE MERGERS BEING PROPOSED?
   Over the past several years their have been efforts to increase the sales of
   the Managed Allocation Funds.  However despite these efforts the funds have
   continued to experience net redemptions.  As a result we are
   asking the shareholders of all 3 Managed Allocation Funds to approve
   "reorganizationing" into Federated MDT Balanced Fund (FMDTBF).  FMDTBF has a
   similar investment strategy, investing in a balance of stocks and bonds, and
   has had an attractive performance track record. See the total returns listed
   below.

HOW WILL THE CLASSES BE MAPPED/MERGED INTO FEDERATED MDT BALANCED FUND?
   Institutional Shares (IS) from all 3 Managed Allocation Portfolio's will be
   merged in the Class A (at NAV) shares of Federated MDT Balanced Fund.
   Select Shares (SEL) from all 3 Managed Allocation Portfolio's will be merged
   in the Class C shares of Federated MDT Balanced Fund.

WHAT ABOUT FUND PERFORMANCE?
   The performance history of Federated MDT Balanced Fund will survive post-
   reorganization. The following chart shows performance comparison as of
   6/30/07 (no-load Total Return) for Class A (FMDTBF)/Institutional Shares
   (Managed Allocation Funds) and Class C (FMDTBF)/Select shares (Managed
   Allocation Funds).

   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 may be lower or
   higher than what is stated.  To view performance current to the most recent

   *The Federated MDT Balanced Fund is the successor to the MDT Balanced 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 the MDT
   Balanced Fund.  Returns shown for Class A and C Shares (inception date
   9/15/05) for the periods prior to their inception are derived from the
   historical performance of Institutional Class of the fund during such periods
   and have been adjusted to reflect the higher total annual operating expenses
   of each specific class.

WHAT IS THE IMPACT TO SHAREHOLDERS?
   Shareholders will continue to be invested in a diversified portfolio that is
   allocated between stocks and bonds.  However there are some differences in
   the investment strategy (see N-14 for comparison). The mergers are
   anticipated to be a tax-free reorganization with the shareholder in most
   cases moving into a lower net fee fund/class.  All capital gains and income
   will be distributed to shareholders of the Managed Allocation Funds prior to
   the mergers.

WHAT IS THE IMPACT ON EXPENSES?
    All fund/class mergers with the exception of FMAF will experience a decrease
    in fund net expenses.  Shareholders of the Select Services share class of
    Federated Moderate Allocation Fund (FMAF) will be moving into a Fund with
    slightly higher expenses (.02 bp).  The current net expenses (after waivers)
    are shown below for each of the Managed Allocation Funds plus the current
    and anticipated post merger expenses for the Federated MDT Balanced Fund.
    (The post merger expenses assume that all proposed mergers are consummated)
