Dear Financial Advisor:

I am writing to notify you that your clients in Seligman LaSalle International
Real Estate Fund, Inc. should have received a proxy statement detailing several
proposals with respect to the pending acquisition of J. & W. Seligman & Co.
Incorporated, the manager of the Fund, by RiverSource Investments, LLC, a
subsidiary of Ameriprise Financial, Inc.

The proxy statement seeks stockholder approval of the following proposals:

      o a new investment advisory agreement between the Fund and RiverSource;

      o a new sub-advisory agreement between RiverSource and the Fund's current
      sub-adviser, LaSalle Investment Management (Securities), L.P. ("LaSalle
      US");

      o a new delegation agreement between LaSalle US and its Netherlands-based
      affiliate, LaSalle Investment Management Securities B.V.; and

      o the election of ten new directors for the Fund.

A Special Meeting of Stockholders will be held on Tuesday, October 7, 2008 at
which stockholders will be asked to vote on the proposals listed above, each as
described in the proxy statement.

We ask that you encourage your clients to vote their proxies in favor of the
proposals as soon as possible. Your clients should complete, date, sign and
return their proxy card by mail, or authorize their proxy by telephone or via
the Internet, or they may vote in person at the Special Meeting, as described in
the proxy statement. If any of your clients need assistance voting their shares,
please have them call Georgeson Inc., the Fund's proxy solicitors, at
888-679-2865.

Following the acquisition of Seligman by RiverSource and approval of the new
agreements, the Fund will continue to be managed by the same investment team,
and its investment objectives and policies will remain unchanged.

If you have any questions, please contact your Seligman Regional Sales
Representative, or call Seligman Advisors, Inc. at 800-221-2783.

We appreciate your help, and thank you for your ongoing support.

Sincerely,

Charles W. Kadlec
Managing Director
