ITEM 5.  OTHER EVENTS.
         ------------

      This  Form  8-K/A is being  filed to amend  the Form 8-K  filed by  Westco
Bancorp,  Inc.  on  August 24,  1998,  in order to reflect an  amendment  to the
definitive merger agreement that was described in the original report.

      On September 1, 1998,  Westco Bancorp,  Inc.  announced that it has agreed
with MAF Bancorp,  Inc. to amend the terms of the  previously  announced  merger
agreement pursuant to which MAF Bancorp, Inc. is to acquire Westco Bancorp, Inc.
The  amendment  reflects a change in  accounting  treatment for the merger which
will be  accounted  for  as  a  purchase  transaction  rather than as a  pooling
of  interests.  A copy of the press  release is  filed as  Exhibit  99.1 to this
Form 8-K/A and is incorporated herein by reference.

      Westco Bancorp also announced that its Board of Directors approved a stock
repurchase  plan under  which the  company is  authorized  to  repurchase  up to
150,000 shares of its common stock.

                          Forward-Looking Information
                          ---------------------------

discussed in these forward-looking  statements.  Factors that might cause such a
difference  include,  but are not  limited  to: (1)  inability  to realize  cost
savings from the merger to the full extent  expected or within the expected time
frame; (2) lower than expected revenues  following the merger;  (3) inability of
MAF or Westco to complete the announced  stock  repurchase  programs  within the
contemplated  timeframe  or stock price  ranges;  (4)  significant  increases in
competitive pressures among depository institutions;  (5) higher r than expected
costs or difficulties  related to the integration of the business of Westco; (6)
changes in the interest rate  environment  that result in reduced  interest rate
margins;  (7) deterioration of general economic conditions, either nationally or
in the  Company's  market area;  and (8) adoption of  legislation  or regulatory
changes that adversely affect the business of the combined company.
