FUND DISCLOSURE

   1   International investing involves additional risks, including currency
       fluctuations, differences in accounting standards, economic and political
       instability, illiquidity and higher trading costs, and differences in
       foreign regulations, all of which are magnified in emerging markets. The
       Fund may purchase securities in initial public offerings, which can be
       very volatile and carry high transaction costs.

   2   The Fund may invest in initial public offerings, can be very volatile and
       carry high transaction costs.

   3   Funds that concentrate on specific sectors or a relatively small number
       of securities may be subject to greater volatility than that of other
       mutual funds.

   4   In order to achieve the Fund's objective, the manager uses sophisticated
       investment strategies such as leverage, short selling, and investing in
       derivatives and ETFs. These strategies cause the Fund to have greater
       risk and volatility, and higher expenses, than those of other
       investments.

   5   The Nationwide Optimal Allocations Funds are designed to provide
       diversification and asset allocation across several types of investment
       strategies and asset classes.

       Each Fund is subject to different levels of risk, based on the types and
       sizes of its underlying asset class allocations. Each Fund's underlying
       funds are subject to specific investment risks such as those associated
       with a concentrated, market-sector or asset class-focused portfolio (such
       as REITs), small companies, international securities, initial public
       offerings, short selling, short-term trading, bonds and short-term
       instruments.




       There is no assurance that a diversified portfolio will produce better
       results than a nondiversified portfolio.

   6   Small-company stocks have higher risks than the stocks of larger, more
       established companies and have significant short-term price volatility.

   7   The Fund may purchase securities in derivatives and initial public
       offerings, which can be very volatile and carry high transaction costs.

   8   The Fund may invest in real estate investment trusts (REITs) that are
       more volatile than other types of securities.

   9   Value stocks can react differently to issuer, political, market and
       economic developments than the market overall and other types of stocks.
       This can cause the Fund to underperform other funds using different
       investment styles.

  10   For some investors, income from the Fund may be subject to state and
       local taxes, and the Federal Alternative Minimum Tax

INVESTORS SHOULD CAREFULLY CONSIDER A FUND'S INVESTMENT OBJECTIVES, RISKS, FEES,
CHARGES AND EXPENSES BEFORE INVESTING ANY MONEY. TO OBTAIN THIS AND OTHER FUND

OUTBOUND CALLING GUIDE TO FINANCIAL ADVISORS

Here are the most important points to communicate to financial advisors
regarding the proposed reorganization:

     o   The proxy materials mailed to shareholders relate to the reorganization
         proposal of 26 Nationwide mutual funds into corresponding portfolios of
         Aberdeen Funds. List of funds can be found on the following page.

     o   Shareholders of the Nationwide Funds included in the reorganization
         proposal who owned shares as of Feb. 29, 2008 will receive the proxy
         materials and voting instructions by mail. Following the mailing,
         certain clients may also be contacted by phone to solicit their vote.

     o   Currently, Aberdeen Asset Management Inc. is the one of the largest
         subadvisers to the Nationwide Funds. In November 2007, the Nationwide
         Mutual Funds' Board of Trustees approved the proposal and determined
         that the reorganization is in the best interest of shareholders, and
         recommends that your clients vote FOR the proposal.

     o   If the proposal is approved, your client will become a shareholder of
         Aberdeen Funds. Aberdeen will serve as the investment advisor and the
         funds will be managed by the same portfolio managers (except for the
         Nationwide Tax-Free Income Fund) who currently manage their Nationwide
         Fund. Upon shareholder approval, Aberdeen Tax-Free Income will be
         subadvised by Credit Suisse Asset Management, LLC

     o   If you receive calls regarding this proxy from your clients, please let
         them know that they should not discard their proxy card included in the
         mailing and encourage them to vote immediately.

     o   If the client discarded their material, an additional proxy card can be
         obtained in one of two ways:
                   1. Client can call 866-745-0266
                   2. Advisor can contact their firm's proxy department.

     o   Shareholders have three ways to vote:
         1. By Internet - Visit the website listed on proxy card.
         2. By Phone - Call the toll-free number listed on the proxy card.
         3. By Mail - Sign/date the proxy card and return in the postage-paid
            envelope.

o        Advisors can vote if their client has authorized them to vote on their
         behalf. Advisor should contact their firm's proxy department and
         provide them with the following information. This process will vary by
         firm.
         1. Account Name/Title
         2. Account #
         3. CUSIP & # of shares
         4. Instructions on how the vote is to be cast (For, Against, Abstain)
