(the "Company") filed a current report on Form 8-K regarding a temporary suspension of trading (the "Blackout Period") under the Elgin Financial Center, SB 401(k) Employee Benefit Plan and Trust (the "Plan"). The reason for the Blackout Period was to allow the Plan's recordkeeper time to process merger consideration election forms in connection with the proposed merger of the Company with and into MAF Bancorp, Inc. The Company originally communicated to its directors and executive officers that the end of the Blackout Period would be January 5, 2006; however the Plan's recordkeeper requires additional time to process the merger consideration election forms following the closing of the merger by and between MAF Bancorp, Inc. and the Company. Accordingly a revised notice was provided to directors and executive officers on January 3, 2006 informing them of the extension of the Blackout Period to the week of February 6, 2006. Attached hereto as Exhibit 99.1 and incorporated by reference herein is a copy of the revised notice. Other than the extension of the ending date of the Blackout Period, there are no material changes to the information contained in the current report on Form 8-K filed on November 4, 2005.
