      MAF BANCORP REPORTS FOURTH QUARTER EARNINGS OF $.27 PER DILUTED SHARE

Exclusive of balance sheet restructuring and certain tax charges, diluted EPS totals $.75 per share for the
fourth quarter and $2.99 for 2006

Clarendon Hills, Illinois, January 29, 2007 — MAF Bancorp, Inc. (MAFB) reported net income for the quarter ended December 31, 2006 of $9.1 million, or $.27 per diluted share, compared to net income of $27.1 million, or $.83 per diluted share in last year’s fourth quarter. Net income for the current quarter was reduced by $12.1 million, or $.36 per diluted share, due to the previously announced balance sheet restructuring. In addition, the current period’s results were reduced by certain tax charges of $4.0 million, or $.12 per diluted share, primarily relating to reserves established in connection with uncertainties arising from a recent tax authority audit. Excluding these balance sheet restructuring charges and tax charges, 2006 fourth quarter net income would have been $25.2 million, or $.75 per diluted share.

Net income for the year ended December 31, 2006 was $84.6 million or $2.51 per diluted share compared to $103.4 million or $3.13 per diluted share for 2005. Excluding the balance sheet restructuring and certain tax charges, 2006 net income would have been $100.7 million, or $2.99 per diluted share.

Allen Koranda, Chairman of the Board and Chief Executive Officer commented, “The restructuring better positions our balance sheet during this difficult interest rate environment. It will improve our net interest income and net interest margin, without increasing interest rate risk. Despite these positive effects, we expect the inverted yield curve and housing market conditions will challenge financial results in 2007. Our focus is on continuing to grow our higher-yielding asset categories, particularly through our business banking operation where we are encouraged with our recent results. Our conservative approach of developing this business through organic growth has been successful over the past few years, with solid growth rates in both loan and deposit balances and excellent credit quality experience.”

Balance Sheet Restructuring

The balance sheet restructuring plan, which we announced on December 27, 2006, involved selling lower-yielding mortgage loans ($220 million) and investments ($531 million) and repaying higher cost borrowings ($502 million), with the balance of the proceeds invested in shorter-term investment securities to provide liquidity. These funds will be available for reinvestment in higher-yielding assets as the Company continues its strategy of increasing the concentration of business and home equity loans in its portfolio.

We recorded restructuring charges in the fourth quarter of $19.9 million, or $12.1 million on an after-tax basis, equal to $.36 per diluted share. The pre-tax charge included a $12.9 million other-than-temporary

impairment on securities, a $4.2 million lower of cost or market adjustment on loans held for sale and $2.8 million relating to prepayment of borrowings. Total restructuring charges were less than originally estimated primarily due to lower prepayment charges recorded in connection with the repayment of borrowings. The Company currently expects that the balance sheet restructuring will contribute $9.8 million, or $.18 per diluted share, to net interest income in 2007.

While the charges relating to the restructuring have been fully reflected in the fourth quarter income statement, the resulting shrinkage in the Company’s balance sheet from the restructuring was not yet reflected at December 31, 2006. The December repayment of borrowings was primarily funded from short-term Federal Home Loan Bank borrowings, which were repaid in early January with proceeds from the sale of investment and mortgage-backed securities that were part of the restructuring.

For a reconciliation of 2006 actual results to adjusted results discussed in this press release that exclude the balance sheet restructuring and certain tax charges, see “Reconciliation of GAAP to Non-GAAP Financial Measures” included later herein.

Average interest-bearing liabilities (000's)	$	9,498,166			8,671,094	$	9,506,348			8,360,019

Net Interest Margin: 4^th Quarter 2006 v. 3^rd Quarter 2006. The net interest margin declined 17 basis points during the quarter primarily due to the cost of interest-bearing liabilities continuing to increase at a faster pace than the yield on interest-earning assets. In addition, the Bank was running higher levels of short-term liquidity as residential mortgage volumes continued to weaken and the balance sheet restructuring strategy was under consideration. Continuing the trend of recent quarters, the cost of interest-bearing liabilities in the current period was impacted by competitive pressures on core deposit pricing and a continued change in our mix of deposits due to consumers shifting deposits into higher-yielding accounts. While we expect the balance sheet restructuring will add 20-25 basis points to net interest margin compared to the fourth quarter of 2006 and also expect to see some benefit from mortgage loan repricings during the year, we expect further margin expansion will be difficult as a result of the continued rise in deposit funding costs and the prolonged nature of the inverted yield curve environment.

2

Net Interest Margin: 4^thQuarter 2006 v. 4^thQuarter 2005.Comparing the current quarter to the fourth quarter of 2005, net interest margin declined by 34 basis points. The rise in short-term interest rates, a flattening and inverted yield curve environment, lower dividend yield on our investment in Federal Home Loan Bank of Chicago stock, higher deposit pricing driven by increased deposit pricing competition and a continued shift of funds out of lower cost core deposits into higher-rate certificates of deposit and money market accounts, have all negatively impacted our net interest margin over the past year. During the year, we repurchased 1.9 million shares of stock using borrowed funds, which positively impacted earnings per share results but had the effect of reducing net interest margin. We also increased our investments in bank-owned life insurance (earnings from which are classified as non-interest income) and in real estate held for development in the last twelve months which negatively impacts net interest margin.

⁽¹⁾     Certain loan reclassifications have been made for December 31, 2005 to conform to current period classification.

To further our strategy of shifting our loan portfolio mix into higher-yielding loan categories, during 2006 we limited balance sheet growth in lower-yielding one- to four-family residential loans by selling more of our originations. One- to four-family loan balances declined by nearly $400 million during the current quarter, of which (about half of which related to the balance sheet restructuring), to 53.9% of total loans at December 31, 2006, compared to 59.0% a year earlier. Multi-family, commercial real estate, construction, land and commercial business loans increased to 28.6% of total loans at year-end compared to 22.2% a year ago.

⁽¹⁾ Total revenue equals net interest income plus non-interest income exclusive of balance sheet restructuring charges.

Pre-tax restructuring charges included in non-interest income for the fourth quarter were $17.1 million. This included a $4.2 million lower of cost or market adjustment on loans transferred to held for sale and $12.9 million of other-than-temporary impairment charges on investment and mortgage-backed securities identified for sale. Exclusive of these charges, non-interest income increased by 10.9% compared to the fourth quarter of 2005. The increases are primarily the result of higher gains on sale of loans and loan servicing rights,

higher deposit service fee income, and increased income from bank-owned life insurance investments. Non-interest income for 2006 was up by 14.6% from 2005, exclusive of the impact of restructuring charges.

Despite lower one- to four-family mortgage loan volume for the fourth quarter and year ended December 31, 2006 compared to the prior year, our strategy to sell more of our loan originations resulted in a 73% increase in one- to four-family loan sale volume in the current quarter compared to the fourth quarter of 2005, and a 70% increase on a year-over-year basis. Loan sale gains, exclusive of the lower of cost or market adjustment to loans held for sale (included in the balance sheet restructuring charge), were $3.5 million, up 125% from last year’s fourth quarter. Margins on loan sales improved in the current quarter due to increased margins realized on ALT-A mortgage sales and selling more loans on a servicing-released basis. Higher sales volume of equity lines of credit during the current quarter also impacted loan sales gains.

During the fourth quarter, the Company completed a sale of mortgage servicing rights on approximately $963 million of loans, or 27% of its one- to four-family mortgage loans serviced for others portfolio, at a pre-

4

tax gain of $3.6 million. The loan servicing rights were sold to take advantage of an increase in servicing values and represented primarily single service customers. The Company had a similar transaction in last year’s fourth quarter, selling servicing rights on approximately $750 million of loans for a pre-tax gain of $2.4 million.

Loan servicing income increased for both the quarter and the year ended December 31, 2006 compared to prior year periods. This was primarily due to continued growth in the loans serviced for others portfolio and lower mortgage servicing rights amortization expense as loan prepayments have slowed in the servicing portfolio. Loan servicing fee income is expected to decline in 2007 due to the impact of the loan servicing rights sale and the current conditions in the mortgage market.

Deposit Account Service Fees

	Three Months Ended December 31,					Year Ended December 31,
	2006			2005		2006			2005
Deposit account service charges (000's)	$	10,592			9,436	$	41,837			35,193
Deposit account service fees / total revenue (exclusive of balance sheet restructuring charges)		12.2	%		10.7		11.9	%		10.2
Number of checking accounts (period end)		266,200			252,200		266,200			252,200

We experienced a 12.3% increase in deposit account service charges for the current three-month period compared to last year’s fourth quarter and an 18.9% increase during 2006 compared to 2005. The growth reflects increases in debit card activity and higher consumer overdraft activity due in part to allowing overdrafts at ATMs. The expansion of the deposit base relating to the February 2006 EFC acquisition also increased overall service fees.

Real Estate Development Operations

	Three Months Ended December 31,					Year Ended December 31,
	2006			2005		2006		2005
Real estate development income (loss) - total (000's)	$	(306	)		2,762	$	785		2,928
Residential lot sale closings		—			123		86		123
Pending lot sales (period end)		33			85		33		85
Real estate held for development or sale (period end) (000's)	$	83,049			50,066	$	83,049		50,066

As previously reported, the loss in real estate development in the fourth quarter of 2006 resulted from the Company’s decision not to exercise an expiring option to purchase a parcel of real estate in Plainfield, IL, which resulted in a write-off of an earnest money deposit and other costs. The slow real estate sales market and the considerable investment the Company has in the Springbank development in Plainfield led to this decision. There were no lot sales in Springbank during the fourth quarter, and 33 lots were under contract at December 31, 2006. The Company currently expects that lot sales in 2007 will be negatively impacted by the slowdown in the real estate market as the increase in inventory of existing homes for sale and uncertain outlook for new home sales has reduced current builder demand for new lots.

The increase in the balance of investment in real estate held for development or sale as compared to a year ago relates primarily to additional land purchases and development cost expenditures related to Springbank.

Non-Interest Expense

	Three Months Ended December 31,					Year Ended December 31,
	2006			2005		2006			2005
Total non-interest expense (000's)	$	49,593			44,936	$	198,070			186,074
Total non-interest expense, exclusive of balance sheet restructuring charges (000's)		46,780			44,936		195,257			186,074
Non-interest expense to average assets, exclusive of balance sheet restructuring charges		1.66	%		1.74		1.73	%		1.86
Efficiency ratio (1)		56.16			52.41		56.07			54.31

⁽¹⁾ The efficiency ratio is calculated by dividing non-interest expense exclusive of restructuring charges by the sum of net interest income and non-interest income exclusive of restructuring charges and net gain/(loss) on sale and write-down of mortgage-backed and investment securities, mortgage servicing rights and fixed assets.

Total non-interest expense in the current quarter increased $4.7 million compared to the fourth quarter of 2005. The current quarter includes $2.8 million of charges related to the prepayment of $502 million of borrowings as part of the balance sheet restructuring. Compensation and benefits increased by $1.6 million, or 7.0%, due to normal annual salary increases and increased employee headcount, partly due to our acquisition of EFC Bancorp in February 2006.

The Company is focused on controlling non-interest expenses in this difficult operating environment. Non-interest expense exclusive of restructuring charges grew at only 4.1% for the quarter and 4.9% for the year ended December 31, 2006 compared to the same periods a year ago, despite additional headcount and occupancy costs arising from the acquisition of EFC Bancorp and opening two denovo branches in late 2005. These efforts to carefully monitor and control non-interest expense levels will continue across all business lines in 2007.

Non-interest expense totaled $198.1 million in 2006 including the prepayment charges noted above. This compared to $186.1 million reported for 2005. Compensation and benefits expense increased by 5.8% during 2006 while occupancy and equipment costs increased by 8.2% over this same period. The increase in these categories is primarily due to the impact of the EFC transaction and normal salary increases. Amortization of core deposit intangibles increased as a result of the EFC acquisition. Lower advertising expenses were due to lower promotional campaign activity in 2006 compared to last year. Professional expense decreased $2.0 million primarily due to lower consulting fees. In 2005 we incurred consulting fees related to various process improvements including an automated work flow system for the mortgage loan division and Sarbanes-Oxley and Bank Secrecy anti-money laundering compliance costs.

Income Tax Expense

Income tax expense totaled $9.8 million in the current quarter, equal to an effective income tax rate of 51.7%, compared to 35.0% reported for the fourth quarter of 2005. The increase in income taxes and the effective tax rate in the current quarter primarily results from $4.0 million of charges taken to adjust tax reserves due to uncertainties arising from a proposed assessment made in a recent tax authority audit of prior year tax returns, as well as for other potential tax liabilities and uncertainties. The Company disagrees with the proposed tax assessment and intends to defend its tax filing positions. Exclusive of these fourth quarter charges and the balance sheet restructuring charges, the Company’s effective tax rate for the current quarter would have been 35.0%.

Income tax expense totaled $49.0 million in 2006, equal to an effective income tax rate of 36.7%, compared to $54.5 million or 34.5% reported for 2005. The increase in the effective tax rate compared to the prior year period was primarily attributable to certain tax charges recorded in the fourth quarter.

Provision for loan losses (quarter ended)		1,350			900		1,500
Net charge-offs (quarter ended)		1,821			896		1,340

The increase in non-performing loans in the current quarter primarily relates to our residential loan portfolio. Also contributing to the increase in non-performing loans at December 31, 2006 is $5.6 million related to one loan on a commercial office building that resulted from the Bank advancing funds under a standby letter of credit in December as previously disclosed. During the quarter, the Bank recorded an additional $200,000 charge-off related to this loan. The loan is expected to be repaid in the first quarter of 2007. At December 31, 2006, loans secured by one- to four-family residential real estate comprised 83.5% of non-performing loans compared to 88.7% at September 30, 2006 and 93.1% at December 31, 2005.

Most of the charge-offs in the quarter were related to the residential loan portfolio, primarily home equity lines of credit. We have taken steps over the past year to enhance our residential portfolio risk management which has led to tightened underwriting standards for some of the nontraditional mortgage products we introduced over the past several years. We have also been selling more of the loans we originate of certain product types that we believe have higher risk of loss as part of our risk management strategies. The provision for loan losses in the current quarter reflects the level of charge-offs, offset by the $404 million shrinkage in the loan portfolio, which includes $220 million of loans transferred to loans held for sale as part of the restructuring, as well as the increase in non-performing loans and portfolio delinquencies, adverse housing market conditions and the shift in the mix of the portfolio.

Since December 31, 2005 deposits have increased $820.5 million primarily due to deposits added in the EFC acquisition. Intense rate competition has made organic deposit growth challenging during 2006. Despite increases in interest rates and competition for deposits, the Company has been successful in maintaining a stable retail deposit base at attractive rates compared to wholesale funding costs.

In December 2006, $400 million of short-term open line advances were used to fund the majority of the $502 million of fixed-rate advances repaid as part of the balance sheet restructuring. The open line advance was repaid in January 2007 using proceeds from the sales of investment and mortgage-backed securities.

Stockholders’ Equity

During the current quarter, we declared $8.2 million in cash dividends. The after-tax unrealized loss on securities held for sale improved by $10.3 million in the current quarter. This was primarily due to the recognition during the fourth quarter of $7.9 million of losses on investments identified for sale as part of the balance sheet restructuring. The Bank’s tangible, core and risk-based capital ratios at December 31, 2006 exceeded minimum and well-capitalized regulatory capital requirements with an additional increase expected in January from the full impact of the balance sheet restructuring. These higher capital levels will provide additional financial flexibility. Return on equity for the three months ended December 31, 2006 was 9.43%, exclusive of balance sheet restructuring charges and certain tax charges. This compared to 11.13% for the fourth quarter of 2005. Return on tangible equity for the current quarter was 15.26%, exclusive of these charges, compared to 16.45% for the fourth quarter of 2005. For information regarding the calculation of return on equity and return on tangible equity ratios exclusive of the balance sheet restructuring and certain tax charges, see “Reconciliation of GAAP to Non-GAAP Financial Measures.”

MAF BANCORP, INC. AND SUBSIDIARIES
RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES

This press release contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America, or GAAP. The Company’s management uses tangible book value per share, tangible stockholders’ equity to tangible assets ratio and return on average tangible equity in its analysis of the Company’s performance and financial condition and believes this presentation provides useful supplemental information that is helpful in understanding our financial condition and results, as it provides a method to assess management’s success in managing alternatives for the utilization of tangible capital.

The Company believes net income, non-interest income and non-interest expense adjusted for the balance sheet restructuring and certain tax charges is useful supplemental information to better understand the core operating performance of the Company. The excluded tax charges relate to adjustments to tax reserves for prior year periods that were recorded in the fourth quarter because of uncertainties that recently arose relating to an unresolved tax authority audit and other developments.

These disclosures should not be considered an alternative to GAAP, nor are they necessarily comparable to non-GAAP performance measures that might be presented by other companies.

Tangible Book Value Per Share

Tangible book value per share is calculated by dividing (a) stockholders’ equity less the sum of goodwill and core deposit intangibles, by (b) common shares outstanding. The following table presents a reconciliation of stockholders’ equity to tangible stockholders’ equity (in thousands):
