                                EXPLANATORY NOTE

DEREGISTRATION OF SECURITIES

         On April 20, 1994, Fidelity Bancorp, Inc., a Delaware corporation
("Fidelity Bancorp"), filed with the Securities and Exchange Commission (the
"Commission") a Registration Statement on Form S-8 (File No. 333-78000) (the
"Registration Statement") registering a total of 363,687 shares of its common
stock, par value $.01 per share, for issuance and sale pursuant to the Fidelity
Bancorp, Inc. 1993 Stock Option Plan for Outside Directors and the Fidelity
Bancorp, Inc. 1993 Incentive Stock Option Plan (together, the "Plans"). Of the
shares of Common Stock initially registered (as adjusted to give effect to a
three-for-two stock split of Fidelity Bancorp's Common Stock that was declared
on January 22, 2002), 154,506 shares were not issued pursuant to the Plans.

         As a result of Fidelity Bancorp's merger into MAF Bancorp, which became
effective July 21, 2003, all outstanding shares of common stock of Fidelity
Bancorp were converted into the right to receive shares of MAF Bancorp common
stock and all outstanding options to purchase Fidelity Bancorp common stock
granted pursuant to the Plans were either cancelled or converted into options to
purchase MAF Bancorp common stock. Accordingly, shares of Fidelity Bancorp
common stock may no longer be issued pursuant to the Plans. This Post-Effective
Amendment No. 1 to the Registration Statement is being filed to deregister the
154,506 shares of Common Stock of Fidelity Bancorp formerly available for
issuance under Plans and registered under the Registration Statement.

         Pursuant to the requirements of the Securities Act of 1933, as amended,

Post-Effective Amendment No. 1 to the Registration Statement to be signed on its
behalf by the undersigned, thereunto duly authorized, in the Village of
Clarendon Hills, State of Illinois, on this 22nd day of July 2003.
