Dear Shareholder:

   Each of your Funds will hold a Joint Special Meeting of Shareholders on
November 7, 2001 at 10:00 a.m., Eastern Time, at the principal executive
offices of North American Funds, 286 Congress Street, Boston, Massachusetts
02210. If you are a shareholder of record as of the close of business on
Monday, September 17, 2001, you are entitled to vote at the meeting and at any
adjournment of the meeting.

   The meeting has been called to give you the opportunity to vote on certain
important proposals affecting your Fund. These proposals have arisen in
connection with the recent acquisition of American General Corporation by
American International Group, Inc.

   First, you are being asked to vote on the approval of a new investment
advisory agreement between North American Funds, on behalf of your Fund, and
American General Asset Management Corp. ("AGAM"), and, where applicable, a new
subadvisory agreement between AGAM and American General Investment Management,
L.P., or an affiliate. In addition, you are being asked to vote on an Agreement
and Plan of Reorganization that would reorganize your Fund into a corresponding
SunAmerica Mutual Fund. In connection with each reorganization, you will
receive shares of the corresponding SunAmerica fund in exchange for shares of
your Fund. The shares of the SunAmerica fund that you receive will have the
same aggregate net asset value as the shares of your Fund immediately prior to
the reorganization. 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.

   The accompanying proxy statement and prospectus includes a detailed
description of each proposal. Please read the enclosed materials carefully and
cast your vote. Remember, your vote is extremely important, no matter how large
or small your holdings. By voting now, you can help avoid additional costs that
would be incurred with follow-up letters and calls.

   To vote, you may use any of the following methods:

  . By Mail. You can vote your shares by completing and signing the enclosed
    proxy card(s), and mailing it in the enclosed postage paid envelope. If
    you need any assistance, or have any questions regarding a proposal,
    please call North American Funds' information agent, Georgeson
    Shareholder, at 1-888-850-2811.

  . By Telephone. If you have any questions on how to vote your shares or if
    you would like to vote by telephone, call 1-888-221-0697 toll free. Enter
    your 14 digit control number from your proxy card to enter your vote.

  . By Internet. Finally, you may vote via the Internet. To do so, have your
