               MAF BANCORP, INC. TO ACQUIRE FIDELITY BANCORP, INC.

Clarendon Hills, Illinois, December 17, 2002 - MAF Bancorp, Inc. (NASDAQ:MAFB)
and Fidelity Bancorp, Inc. (NASDAQ:FBCI) jointly announced today that MAF has
agreed to acquire Fidelity in an all-stock transaction. Allen Koranda, Chairman
and CEO of MAF and Raymond Stolarczyk, Chairman and CEO of Fidelity announced
that their respective boards of directors have approved a definitive agreement
under which Fidelity will be merged with MAF.

Pursuant to the merger agreement, each share of Fidelity common stock will be
converted into .89 shares of MAF common stock. Based on the closing price of MAF
common stock on December 16, 2002, the transaction has a current value of $101.4
million in the aggregate and $31.00 per Fidelity share. The transaction, which
is subject to regulatory approval and the approval of Fidelity stockholders, is
structured to be tax-free to the stockholders of Fidelity. The companies
currently expect the transaction to close in mid-2003. In connection with the
merger, Fidelity's bank subsidiary, Fidelity Federal Savings Bank, will be
merged with Mid America Bank, a wholly-owned subsidiary of MAF Bancorp. The
merger of the banks will provide Mid America Bank with five additional branch
locations in the Chicago area.

Allen Koranda, Chairman and Chief Executive Officer of MAF Bancorp, said, "We
are excited about the opportunity to combine with a quality organization like
Fidelity. By adding nearly $450 million in deposits, the transaction will allow
us to deepen our penetration into the Chicago banking market. We appreciate the
confidence that Ray and his Board of Directors have placed in us, allowing us to
build upon their strong franchise."

Raymond Stolarczyk, Chairman and Chief Executive Officer of Fidelity Bancorp,
added, "We have built a quality financial institution over many years due to our
loyal customers and employees. We believe the next step in our progression is to
partner with an organization that shares our retail banking philosophy and has
proven successful in competing in the Chicago area banking markets. MAF was the
logical choice." Mr. Stolarczyk will join MAF's board of directors following the
acquisition.

MAF expects to achieve significant cost savings following the integration of the
two companies' respective organizations. The data processing conversion is
expected to be completed in the third quarter of 2003. MAF expects to repurchase
approximately 850,000 of the shares to be issued in the transaction,
representing approximately 3.3% of MAF's projected outstanding shares after the
merger. MAF expects the transaction will be neutral to calendar 2003 earnings
per share and be approximately 1-2% accretive to earnings per share in 2004, in
each case assuming completion of the stock repurchases. MAF currently expects
after-tax merger-related costs will equal approximately 5% of the transaction
value.
