                        IMPORTANT NEWS FOR SHAREHOLDERS

                               ----------------

   While we encourage you to read the full text of the enclosed Proxy Statement
and Prospectus, here is a brief overview of some matters affecting your Fund
that require a shareholder vote.

                           Q&A: QUESTIONS AND ANSWERS

Q.  WHAT IS HAPPENING?

A.  American International Group, Inc. ("AIG") acquired American General
    Corporation on August 29, 2001 in a transaction we call the "AIG Merger."
    AIG is a leading U.S.-based international insurance and financial services
    organization.

  As a result of the AIG Merger, American General Asset Management Corp.
  ("AGAM") and American General Investment Management, L.P. ("AGIM") became
  part of AIG. AGAM serves as investment adviser to your Fund and AGIM serves
  as subadviser. SunAmerica Asset Management Corp. ("SAAMCo") is also part of
  AIG and serves as investment adviser to the SunAmerica Mutual Funds, a
  $7 billion mutual fund complex.

  You are being presented with several important matters to vote on as a
  result of the AIG Merger:

    .  The continuation of your Fund's investment advisory agreement with
       AGAM following the AIG Merger;

    .  The continuation of your Fund's subadvisory agreement with AGIM, or
       an affiliate, following the AIG Merger; and

    .  A proposal to reorganize your Fund with a SunAmerica Mutual Fund. As
       described in more detail below, there is a proposal to combine each
       series of North American Funds with a single corresponding
       SunAmerica Mutual Fund. We refer to each series of North American
       Funds as a "North American Fund," each series of the SunAmerica
       Mutual Funds as a "SunAmerica Fund," and each proposed transaction
       between them as a "Reorganization."

Q.  WHY AM I BEING ASKED TO VOTE ON THE PROPOSED NEW INVESTMENT ADVISORY
    AGREEMENT WITH AGAM IN PROPOSAL NO. 1(a)?

A.  Applicable securities laws require a shareholder vote on a new investment
    advisory agreement whenever there is a change in control of a fund's
    investment adviser, because upon such a change in control, the agreement
    between the investment adviser and the fund terminates automatically.
    Accordingly, because the AIG Merger resulted in a change in control of
    AGAM, and therefore the termination of North American Funds' investment
    advisory agreement with AGAM, shareholder approval of the new investment
    advisory agreement with AGAM is required. The new investment advisory
    agreement that shareholders are being asked to approve is the same in all
    material respects as the North American Funds' previous investment advisory
    agreement with AGAM. The new investment advisory agreement, as approved by
    shareholders, will take effect immediately. If you approve the
    Reorganization applicable to your Fund, the agreement with AGAM will
    terminate when the Reorganization is completed.

  The Board of Trustees of North American Funds, including all of the
  Independent Trustees, unanimously recommends that you vote FOR the proposal
  to approve the new investment advisory agreement with AGAM.


Q.  WHY AM I BEING ASKED TO VOTE ON THE PROPOSED NEW SUBADVISORY AGREEMENT IN
    PROPOSAL NO. 1(b)?

A.  The relevant provisions of the securities laws relating to the change in
    control of an investment adviser also apply to a subadviser. Because the
    AIG Merger resulted in the change in control of AGIM, and therefore the
    termination of the subadvisory agreement between AGAM and AGIM, shareholder
    approval of the new subadvisory agreement between AGAM and AGIM, or an
    affiliate, is required. The new subadvisory agreement that the shareholders
    are being asked to approve is the same in all material respects as the
    previous subadvisory agreement with AGIM. The new subadvisory agreement, as
    approved by shareholders, will take effect immediately. If you approve the
    Reorganization applicable to your Fund, the subadvisory agreement between
    AGAM and AGIM, or an affiliate, will terminate when the Reorganization is
    completed.

  The Board of Trustees of North American Funds, including all of the
  Independent Trustees, unanimously recommends that you vote FOR the proposal
  to approve the new subadvisory agreement with AGIM, or an affiliate.

Q.  WHAT ARE THE REORGANIZATIONS?

A.  In anticipation of completion of the AIG Merger, AGAM and SAAMCo presented
    to the Board of Trustees of North American Funds a proposal to reorganize
    your Fund with a single comparable SunAmerica Fund. Under each relevant
    proposal, your Fund would be combined with the SunAmerica Fund, and you
    would become a shareholder of the corresponding SunAmerica Fund. The Board
    of Trustees of North American Funds unanimously approved each
    Reorganization.

  North American Fund shareholders are asked to approve the Reorganization.
  The attached Proxy Statement and Prospectus describes each proposed
  Reorganization. Specifically, you will find information relating to the
  following Reorganizations:



       North American Fund:                     SunAmerica Fund:
       --------------------                     ----------------
                                             
       Core Bond Fund                           SunAmerica Core Bond Fund
       High Yield Bond Fund                     SunAmerica High Income Fund (to be
                                                renamed the SunAmerica High Yield Bond
                                                Fund)
       Municipal Bond Fund                      SunAmerica Tax Exempt Insured Fund
       Strategic Income Fund                    SunAmerica Diversified Income Fund (to
                                                be renamed the SunAmerica Strategic
                                                Income Fund)
       U.S. Government Securities Fund          SunAmerica U.S. Government Securities
                                                Fund


  The Board of Trustees of North American Funds, including all of the
  Independent Trustees, unanimously recommends that you vote FOR the
  Reorganization.

Q.  HOW WILL THE REORGANIZATIONS AFFECT MY ACCOUNT?

A.  If shareholders approve a Reorganization, your North American Fund shares
    will be exchanged, on a tax-free basis, for an equal aggregate dollar value
    of shares of the SunAmerica Fund. This means that you may end up with a
    different number of shares compared to what you originally held, but the
    total dollar value of your shares will be the same.

  You will receive the same class of SunAmerica Fund shares as the North
  American Fund shares you hold immediately prior to the Reorganization.
  (However, if you own Class C or Institutional Class II shares of a North
  American Fund, you will receive Class II and Class Z shares, respectively,
  of the SunAmerica Fund since these are the classes of SunAmerica Fund
  shares that correspond to North American Fund Class C and Institutional
  Class II shares, respectively.)

                                       2


Q.  WHY DOES THE BOARD RECOMMEND THE REORGANIZATIONS?

A.  Your Board has based this recommendation on its consideration of the
    principal reasons underlying each Reorganization, including the following:
    the fact that, following each Reorganization, shareholders of each North
    American Fund would remain invested in a mutual fund having substantially
    the same or similar investment objective and similar, though not identical,
    investment techniques; the fees and expenses of each Fund; potential
    benefits to shareholders, such as the potential for reduced operating
    expenses over time due to economies of scale; and the fact that no
    Reorganization will adversely affect the interests of the corrresponding
    North American Fund shareholders. After each Reorganization, shareholders
    of a North American Fund will hold shares of the same aggregate net asset
    value in the corresponding SunAmerica Fund.

Q.  WHO WILL MANAGE MY FUND AFTER THE REORGANIZATION?

A.  AGAM currently manages the assets of each North American Fund. AGIM is
    currently the subadviser to your Fund. After completion of the
    Reorganizations, SAAMCo will be the manager of each North American Fund as
    part of the corresponding SunAmerica Fund AGIM (or an affiliate) will be
    the subadviser responsible for the day-to-day portfolio management of each
    SunAmerica Fund except the SunAmerica U.S. Government Securities Fund.

Q.  WILL THE REORGANIZATIONS BE TAX-FREE?

A.  The Reorganizations will be accomplished on a tax-free basis. This means
    that you should not realize any federal capital gains (or losses) when your
    North American Fund shares are exchanged for SunAmerican Fund shares.

Q.  HOW DOES THE BOARD OF TRUSTEES OF NORTH AMERICAN FUNDS RECOMMEND THAT I
    VOTE?

A.  After careful consideration, based upon their evaluation of all relevant
    information, and after meeting with counsel to the Independent Trustees
    regarding the legal issues involved, the Board, including the Independent
    Trustees, recommends that you vote FOR all of the proposals on the enclosed
    proxy card.

Q.  WHO GETS TO VOTE?

A.  If you owned shares of a North American Fund on September 17, 2001, you are
    entitled to vote with respect to your Fund, even if you later sold the
    shares. Each share of a North American Fund is entitled to one vote, with
    fractional shares voting proportionally.

Q.  WHY ARE MULTIPLE PROXY CARDS ENCLOSED?

A.  If you are a shareholder of more than one of the North American Funds, you
    will receive a proxy card for each North American Fund in which you own
    shares.

Q.  I'M A SMALL INVESTOR. WHY SHOULD I VOTE?

A.  Your vote makes a difference. If many small shareholders just like you fail
    to vote their proxies, your Fund may not receive enough votes to go forward
    with the Special Meeting of Shareholders and additional costs will be
    incurred through further proxy solicitations.

Q.  HOW DO I VOTE?

A.  You have several different ways to vote. They include mail, speaking with a
    representative on the telephone, and voting on-line over the Internet. If
    you need more information or have any questions on how to vote call 1-888-
    221-0697. If you have any questions on a proposal, please call North
    American Funds' information agent, Georgeson Shareholder, at 1-888-850-
    2811.

  Your vote is important. Please vote promptly to avoid the additional
  expense of another solicitation.
