                             EMPLOYMENT AGREEMENT

     This AGREEMENT is made effective as of April 19, 1990 by and between Mid
America Federal Savings Bank (the "Bank"), a corporation organized under the
laws of the United States, with its principal administrative office at 55th &
Holmes Streets, Clarendon Hills, Illinois, and Allen H. Koranda ("Executive").
Any reference to "Holding Company" herein shall mean MAF Bancorp, Inc. or any
successor thereto.

     WHEREAS, the Bank wishes to assure itself of the services of Executive for
the period provided in this Agreement; and

     WHEREAS, Executive is willing to serve in the employ of the Bank on a full-
time basis for said period.

     NOW, THEREFORE, in consideration of the mutual covenants herein contained,
and upon the other terms and conditions hereinafter provided, the parties hereby
agree as follows:

1.   POSITION AND RESPONSIBILITIES.

     During the period of his employment hereunder, Executive agrees to serve as
Chairman of the Board of Directors and Chief Executive Officer of the Bank.
During said period, Executive also agrees to serve, if elected, as an officer
and director of any subsidiary or affiliate of the Bank. Failure to reelect
Executive as Chief Executive Officer or failure to nominate Executive to the
Board of Directors or failure to elect the Executive as the Chairman of the
Board if elected as a director without the consent of the Executive shall
constitute a breach of this Agreement.

2.   TERMS AND DUTIES.

     (a)  The period of Executive's employment under this Agreement shall be
deemed to have commenced as of the date first above written and shall continue
for a period of sixty (60) full calendar months thereafter.  Commencing on the
third anniversary date of this Agreement, and continuing at each anniversary
date thereafter, the Agreement shall automatically renew for an additional year
such that the remaining term shall be three (3) years unless written notice is
provided to Executive at least ten (10) days and not more than twenty (20) days
prior to such anniversary date, that his employment shall cease at the end of
twenty-four (24) months following the next anniversary date.

     (b)  During the period of his employment hereunder, except for periods of
absence occasioned by illness, reasonable vacation periods, and reasonable
leaves of absence, Executive shall devote substantially all his business time,
attention, skill, and efforts to the faithful performance of his duties
hereunder including activities and services related to the organization,
operation and management of the Bank; provided, however, that with the approval
of the Board 
<PAGE>
 
of Directors of the Bank ("Board"), as evidenced by a resolution of such Board,
from time to time, Executive may serve, or continue to serve, on the boards of
directors of, and hold any other offices or positions in, companies or
organizations, which, in such Board's judgment, will not present any conflict of
interest with the Bank, or materially affect the performance of Executive's
duties pursuant to this Agreement.

3.   COMPENSATION AND REIMBURSEMENT.

     (a)  The compensation specified under this Agreement shall constitute the
salary and benefits paid for the duties described in Section 2(b). The Bank
shall pay Executive as compensation a salary of not less than $239,000 per year
("Base Salary"). Such salary shall be payable semi-monthly. During the period of
this Agreement, Executive's salary shall be reviewed at least annually; the
first such review will be made no later than December 31, 1990. Such review
shall be conducted by a Committee designated by the Board, and such Committee
may increase said salary. In addition to the salary provided in this Section
3(a), the Bank shall provide Executive at no cost to Executive with all such
other benefits as are provided uniformly to permanent full-time employees of the
Bank.

     (b)  The Bank will provide Executive with employee benefit plans,
arrangements and perquisites substantially equivalent to those in which
Executive was participating or otherwise deriving benefit from immediately prior
to the beginning of the term of this Agreement, and the Bank will not, without
Executive's prior written consent, make any changes in such plans, arrangements
or perquisites which would adversely affect Executive's rights or benefits
thereunder.  Without limiting the generality of the foregoing provisions of this
Subsection (b), Executive will be entitled to participate in or receive benefits
under any employee benefit plans including retirement plans, pension plans,
profit-sharing plans, deferred compensation plans, health-and-accident plan,
medical coverage or any other employee benefit plan or arrangement made
available by the Bank in the future to its senior executives and management
employees, subject to and on a basis consistent with the terms, conditions and
overall administration of such plans and arrangements.  Executive will be
entitled to incentive compensation and bonuses as provided in any plan of the
Bank in which Executive is eligible to participate.  Nothing paid to the
Executive under any such plan or arrangement will be deemed to be in lieu of
other compensation to which the Executive is entitled under this Agreement.

     (c)  In addition to the Base Salary provided for by paragraph (a) of
this Section 3, the Bank shall pay or reimburse Executive for all reasonable
travel and other reasonable expenses incurred by Executive performing his
obligations under this Agreement and may provide such additional compensation in
such form and such amounts as the Board may from time to time determine.

4.   PAYMENTS TO EXECUTIVE UPON TERMINATION OF EMPLOYMENT.

     The provisions of this Section shall in all respects be subject to the
terms and conditions stated in Sections 8 and 15.
<PAGE>
 
     (a)  Upon the occurrence of an Event of Termination (as herein defined)
during the Executive's term of employment under this Agreement, the provisions
of this Section shall apply.  As used in this Agreement, an "Event of
Termination" shall mean and include any one or more of the following:(i) the
termination by the Bank or the Holding Company of Executive's full-time
employment hereunder for any reason other than a Change in Control, as defined
in Section 5(a) hereof or for Cause, as defined in Section 8 hereof; (ii)
Executive's resignation from the Bank's employ, upon any (A) failure to elect or
reelect Executive as the Chief Executive Officer or failure to nominate or
renominate Executive to the Board of Directors or failure to elect or reelect
Executive as Chairman of the Board if elected as a director, (B) material change
in Executive's function, duties, or responsibilities, which change would cause
Executive's position to become one of lesser responsibility, importance, or
scope from the position and attributes thereof described in Section 1, above,
(and any such material change shall be deemed a continuing breach of this
Agreement), (C) liquidation, dissolution, consolidation, or merger of the Bank
or Holding Company in which the Bank or the Holding Company is not the resulting
entity, or transfer of all or substantially all of the assets of the Bank or
Holding Company in which the Bank or Holding Company is not the resulting
entity, or (d) breach of this Agreement by the Bank.  Upon the occurrence of any
event described in clauses (A), (B), (C) or (D), above, Executive shall have the
right to elect to terminate his employment under this Agreement by resignation
upon not less than sixty (60) days prior written notice given within a
reasonable period of time not to exceed, except in case of a continuing breach,
four calendar months after the event giving rise to said right to elect.

     (b)  Upon the occurrence of an Event of Termination, the Bank shall pay
Executive, or, in the event of his subsequent death, his beneficiary or
beneficiaries, or his estate, as the case may be, as severance pay or liquidated
damages, or both, a sum equal to the greater of three (3) times the average of
the three (3) preceding years' Base Salary paid to the Executive or the salary
payable to the Executive for the remaining term of this Agreement; provided,
                                                                   -------- 
however, that if the Bank is not in compliance with its minimum capital
-------                                                                
requirements, such payments shall be deferred until such time as the Bank is in
capital compliance.  At the discretion of the Executive, such payments shall be
made in a lump sum immediately upon the occurrence of an Event of Termination
subject to only the proviso above, or paid monthly during thirty-six (36) months
following the Executive's termination.

     (c)  Upon the occurrence of an Event of Termination, the Bank will cause to
be continued life, health and disability coverage substantially identical to the
coverage maintained by the Bank for Executive prior to his termination. Such
coverage shall cease upon the earlier of Executive's employment by another
employer or thirty six (36) months.

     (d)  On an annual basis on January 2, or if January 2 is not a regular
business day, then on the next such regular business day, of each year,
Executive shall elect whether, in the event amounts are payable under Section
4(b) hereof, such amounts shall be paid in a lump sum or on a pro rate basis
pursuant to such section.  Such election shall be irrevocable for the year for
which such election is made.

5.   CHANGE IN CONTROL.
<PAGE>
 
     (a)  No benefit shall be payable under this Section 5 unless there shall
have been a Change in Control of the Bank or Holding Company, as set forth
below. For purposes of this Agreement, a "Change in Control" of the Bank or
Holding Company shall mean an event of a nature that: (1) would be required to
be reported in response to Item 1 of the current report on Form 8-K, as in
effect on the date hereof, pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 (the "Exchange Act"); or (ii) results in a Change in
Control of the Bank or the Holding Company within the meaning of the Home
Owners' Loan Act of 1933, as amended, and the Rules and Regulations promulgated
by the Office of Thrift Supervision (or its predecessor agency), as in effect on
the date hereof, including Section 574 or such regulations; or (iii) without
limitation such a Change in Control shall be deemed to have occurred at such
time as (a) any "person" (as the term is used in Sections 13(d) and 14(d) of the
Exchange Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3
under the Exchange Act), directly or indirectly, of securities or makes an offer
to purchase securities of the Bank or the Holding Company representing 20% or
more of the Bank's or the Holding Company's outstanding securities ordinarily
having the right to vote at the election of directors except for any securities
of the Bank purchased by the Holding Company in connection with the conversion
of the Bank to the stock form and any securities purchased by the Bank's
employee stock ownership plan and trust; or (b) individuals who constitute the
Board of the Bank or Holding Company on the date hereof (the "Incumbent Board")
cease for any reason to constitute at least a majority thereof, provided that
any person becoming a director subsequent to the date hereof whose election was
approved by a vote of at least three-quarters of the directors comprising the
Incumbent Board, or whose nomination for election by the Holding Company's
shareholders was approved by the same Nominating Committee serving under an
Incumbent Board, shall be, for purposes of this clause (b), considered as though
he were a member of the Incumbent Board; or (c) a merger, consolidation or sale
of all or substantially all the assets of the Holding Company occurs; or (d) a
proxy statement shall be distributed soliciting proxies from stockholders of the
Holding Company, by someone other than the current management of the Holding
Company, seeking stockholder approval of a plan of reorganization, merger or
consolidation of the Holding Company or Bank with one or more corporations as a
result of which the outstanding shares of the class of securities then subject
to the Plan are exchanged for or converted into cash or property or securities
not issued by the Bank or Holding Company; or (e) a tender offer is made for 20%
or more of the outstanding securities of the Bank or Holding Company.

     (b)  If any of the events described in Section 5(a) hereof constituting a
Change in Control have occurred or the Board of the Bank or the Holding Company
has determined that a Change in Control has occurred, Executive shall be
entitled to the benefits provided in paragraphs (c), (d), (e), (f) and (g) of
this Section 5 upon his subsequent termination of employment at any time during
the term of this Agreement (regardless of whether such termination results from
his resignation or his dismissal), unless such termination is because of his
death, disability or for cause. Upon the Change in Control, Executive shall have
the right to elect to terminate his employment with the Bank at any time during
the term of this Agreement.

     (c)  Upon the occurrence of a Change in Control followed by the Executive's
termination of employment, the Bank shall pay Executive, or in the event of his
subsequent
<PAGE>
 
death, his beneficiary or beneficiaries, or his estate, as the case may be, as
severance pay or liquidated damages, or both, a sum equal to three (3) times the
average of the three (3) preceding years' Base Salary paid to the Executive. At
the discretion of the Executive, such payment may be made in a lump sum
immediately upon a Change in Control and termination of employment of Executive
or paid monthly during the thirty-six (36) months following the Executive's
termination.

     (d)  Upon the occurrence of a Change in Control followed by the Executive's
termination of employment, the Bank will cause to be continued life, health and
disability coverage substantially identical to the coverage maintained by the
Bank for the Executive prior to his severance. Such coverage shall cease upon
the earlier of Executive's employment by another employer or upon the expiration
of thirty-six (36) months.

     (e)  Upon the occurrence of a Change in Control, the Executive will have
such rights as specified in the Holding Company's Incentive Stock Option Plan or
any other employee benefit plan with respect to options and such other rights as
may have been granted to Executive under such plans.

     (f)  Upon the occurrence of a Change in Control, the Executive will be
entitled to the benefits under the Bank's Management Recognition and Retention
Plans.

     (g)  Notwithstanding the preceding paragraphs of this Section 5, in the
event that:

     (i)  the aggregate payments or benefits to be made or
          afforded to Executive under said paragraphs (the
          "Termination Benefits") would be deemed to include
          an "excess parachute payment" under 280G of the Code
          or any successor thereto, and

     (ii) if such Termination Benefits were reduced to an amount
          (the "Non-Triggering Amount"), the value of which is
          one dollar ($1.00) less than an amount equal to three
          (3) times Executive's "base amount", as determined in
          accordance with said Section 280G, and the
          Non-Triggering Amount would be greater than the
          aggregate value of the Termination Benefits (without
          such reduction) minus the amount of tax required to be
          paid by Executive thereon by Section 4999 of the Code,
          then the Termination Benefits shall be reduced to the
          Non-Triggering Amount.  The allocation of the reduction
          required hereby among the Termination Benefits provided
          by the preceding paragraphs of this Section 5 shall be
          determined by the Executive.  In the event that
          Executive receives the Non-Triggering Amount pursuant
          to this paragraph (g) and it is subsequently
          
<PAGE>
 
          determined by the Internal Revenue Service or judicial
          authority that Executive is deemed to have received an
          amount in excess of the Non-Triggering Amount, the
          Holding Company shall pay to Executive an amount equal
          to the value of the payments or benefits in excess of
          the Non-Triggering Amount he is so deemed to have
          received.

     (h)  On an annual basis on January 2, or if January 2 is not a regular
business day, then on the next such regular business day, of each year,
Executive shall elect whether, in the event amounts are payable under Section
5(c) hereof, such amounts shall be paid in a lump sum or on a pro rata basis
pursuant to such section.  Such election shall be irrevocable for the year for
which such election is made.

6.   TERMINATION FOR DISABILITY.


     (a)  If, as a result of Executive's incapacity due to physical or mental
illness, he shall have been absent from his duties with the Bank on a full-time
basis for six (6) consecutive months, and within thirty (30) days after written
notice of potential termination is given he shall not have returned to the full-
time performance of his duties, the Bank or the Holding Company may terminate
Executive's employment for "Disability."

     (b)  The Bank will pay Executive, as disability pay, a monthly payment
equal to the greater amount of three-quarters (3/4) of Executive's monthly rate
of Base Salary on the effective date of such termination or $14,937.50. These
disability payments shall commence on the effective date of Executive's
termination and will end on the earlier of (i) the date Executive returns to the
full-time employment of the Bank in the same capacity as he was employed prior
to his termination for Disability and pursuant to any employment agreement
between Executive and the Bank; (ii) Executive's full-time employment by another
employer; (iii) Executive attaining the normal age of retirement; or (iv)
Executive's death. Notwithstanding any other provision to the contrary, the Bank
may apply any proceeds from disability income insurance for Executive which was
paid for by the Bank as partial satisfaction of its obligation under this
Section. The disability payments will be in addition to any benefit payable from
any qualified or non-qualified retirement plans, stock benefit plans or other
programs maintained by the Bank.

     (c)  The Bank will cause to be continued life, health and disability
coverage substantially identical to the coverage maintained by the Bank for the
Executive prior to his termination for Disability. This coverage shall cease
upon the earlier of (I) the date Executive returns to the full-time employment
of the Bank, in the same capacity as he was employed prior to his termination
for Disability and pursuant to an employment agreement between Executive and the
Bank; (ii) Executive's full-time employment by another employer; (iii)
Executive's attaining the normal age of retirement, or (iv) the Executive's
death.
 
<PAGE>
 
     (d)  Notwithstanding the foregoing, there will be no reduction in the
compensation otherwise payable to Executive during any period during which
Executive is incapable of performing his duties hereunder by reason of temporary
disability.

7.   TERMINATION UPON RETIREMENT.

     Termination by the Bank of the Executive based on "Retirement" shall
mean termination in accordance with any retirement arrangement established with
Executive's consent with respect to him.  Upon termination of Executive upon
Retirement, Executive shall be entitled to all benefits under any retirement
plan of the Bank and other plans to which Executive is a party.  In addition,
the Bank will cause to be continued health coverage substantially identical to
the coverage maintained by the Bank for the Executive prior to his Retirement
until his death.

8.   TERMINATION FOR CAUSE.

     The term "Termination for Cause" shall mean termination because of the
Executive's personal dishonesty, incompetence, willful misconduct, any breach of
fiduciary duty involving personal profit, intentional failure to perform stated
duties, willful violation of any law, rule, or regulation (other than traffic
violations or similar offenses) or final cease-and- desist order, or material
breach of any provision of this Agreement. In determining incompetence, the acts
or omissions shall be measured against standards generally prevailing in the
savings institutions industry. Notwithstanding the foregoing, Executive shall
not be deemed to have been terminated for Cause unless and until there shall
have been delivered to him a copy of a resolution duly adopted by the
affirmative vote of not less than a majority of the members of the Board at a
meeting of the Board called and held for that purpose (after reasonable notice
to Executive and an opportunity for him, together with counsel, to be heard
before the Board), finding that in the good faith opinion of the Board,
Executive was guilty of conduct justifying termination for Cause and specifying
the particulars thereof in detail.  The Executive shall not have the right to
receive compensation or other benefits for any period after termination for
Cause.  Any stock options granted to Executive under any stock option plan of
the Bank, the Holding Company or any subsidiary or affiliate thereof, shall
become null and void effective upon Executive's receipt of Notice of Termination
for Cause pursuant to Section 9 hereof, and shall not be exercisable by
Executive at any time subsequent to such Termination for Cause.

9.   NOTICE.

     Any purported termination by the Holding Company or by Executive shall be
communicated by Notice of Termination to the other party hereto.

     For purposes of this Agreement, a "Notice of Termination" shall mean a
written notice which shall indicate the specific termination provision in this
Agreement relied upon and shall set forth in detail the facts and circumstances
claimed to provide a basis for termination of Executive's employment under the
provision so indicated.  "Date of Termination" shall mean (A) if Executive's
employment is terminated for Disability, thirty (30) days after a Notice of
Termination is given (provided that he shall not have returned to the
performance of his duties on 
<PAGE>
 
a full-time basis during such thirty (30) day period), and (B) if his employment
is terminated for any other reason, the date specified in the Notice of
Termination (which, in the case of a Termination for Cause, shall not be less
than thirty (30) days from the date such Notice of Termination is given);
provided that if, within thirty (30) days after any Notice of Termination is
given, the party receiving such Notice of Termination notifies the other party
that a dispute exists concerning the termination, the Date of Termination shall
be the date on which the dispute is finally determined, either by mutual written
agreement of the parties, by a binding arbitration award, or by a final
judgment, order or decree of a court of competent jurisdiction (the time for
appeal therefrom having expired and no appeal having been perfected) and
provided further that the Date of Termination shall be extended by a notice of
dispute only if such notice pursues the resolution of such dispute with
reasonable diligence. Notwithstanding the pendency of any such dispute, the Bank
will continue to pay Executive his full compensation in effect when the notice
giving rise to the dispute was given (including, but not limited to, Base
Salary) and continue him as a participant in all compensation, benefit and
insurance plans in which he was participating when the notice of dispute was
given, until the dispute is finally resolved in accordance with this Agreement.
Amounts paid under this Section are in addition to all other amounts due under
this Agreement and shall not be offset against or reduce any other amounts due
under this Agreement.

10.  POST-TERMINATION OBLIGATIONS.

     (a)  All payments and benefits to Executive under this Agreement shall be
subject to Executive's compliance with paragraph (b) of this Section 10 during
the term of this Agreement and for one (1) full year after the expiration or
termination hereof.

     (b)  Executive shall, upon reasonable notice, furnish such information and
assistance to the Bank as may reasonably be required by the Bank in connection
with any litigation in which it or any of its subsidiaries or affiliates is, or
may become, a party.

11.  NON-DISCLOSURE.

     Executive recognizes and acknowledges that the knowledge of the business
activities and plans for business activities of the Bank and affiliates thereof,
as it may exist from time to time, is a valuable, special and unique asset of
the business of the Bank. Executive will not, during or after the term of his
employment, disclose any knowledge of the past, present, planned or considered
business activities of the Bank or affiliates thereof to any person, firm,
corporation, or other entity for any reason or purpose whatsoever.
Notwithstanding the foregoing, Executive may disclose any knowledge of banking,
financial and/or economic principles, concepts or ideas which are not solely and
exclusively derived from the business plans and activities of the Bank. In the
event of a breach or threatened breach by the Executive of the provisions of
this Section, the Holding Company will be entitled to an injunction restraining
Executive from disclosing, in whole or in part, the knowledge of the past,
present, planned or considered business activities of the Bank or affiliates
thereof, or from rendering any services to any person, firm, corporation, other
entity to whom such knowledge, in whole or in part, has been disclosed or is
threatened to be disclosed. Nothing herein will be construed as prohibiting the
Bank from pursuing other
<PAGE>
 
remedies available to the Bank for such breach or threatened breach, including
the recovery of damages from Executive.

12.  SOURCE OF PAYMENTS.

     All payments provided in this Agreement shall be paid in cash or check from
the general funds of the Bank. The Holding Company guarantees payment and
provision of all amounts and benefits due to the Executive under the Employment
Agreement by and between the Bank and the Executive, if any amounts and benefits
due from the Bank are not timely paid or provided by the Bank, such amounts and
benefits shall be paid or provided by the Holding Company.

13.  EFFECT ON PRIOR AGREEMENTS AND EXISTING BENEFIT PLANS.

     This Agreement contains the entire understanding between the parties hereto
and supersedes any prior employment agreement between the Bank or any
predecessor of the Bank and Executive, except that this Agreement shall not
affect or operate to reduce any benefit or compensation inuring of Executive of
a kind elsewhere provided. No provision of this Agreement shall be interpreted
to mean that Executive is subject to receiving fewer benefits than those
available to him without reference to this Agreement.

14.  NO ATTACHMENT.

     (a)  Except as required by law, no right to receive payments under this
Agreement shall be subject to anticipation, commutation, alienation, sale,
assignment, encumbrance, charge, pledge, or hypothecation, or to execution,
attachment, levy, or similar process or assignment by operation of law, and any
attempt, voluntary or involuntary, to affect any such action shall be null,
void, and of no effect.

     (b)  This Agreement shall be binding upon, and inure to the benefit of,
Executive and the Bank and their respective successors and assigns.

15.  MODIFICATION AND WAIVER.

     (a)  This Agreement may not be modified or amended except by an instrument
in writing signed by the parties hereto.

     (b)  No term or condition of this Agreement shall be deemed to have been
waived, nor shall there be any estoppel against the enforcement of any provision
of this Agreement, except by written instrument of the party charged with such
waiver or estoppel. No such written waiver shall be deemed a continuing waiver
unless specifically stated therein, and each such waiver shall operate only as
to the specific term or condition for the future of as to any act other than
that specifically waived.


16.  REQUIRED PROVISIONS.
<PAGE>

Executive (and his heirs, executors and administrators) to the fullest extent
permitted under Federal law against all expenses and liabilities reasonably
incurred by him in connection with or arising out of any action, suit or
proceeding in which he may be involved by reason of his having been a director
or officer of the Bank (whether or not he continues to be a director or officer
at the time of incurring such expenses or liabilities), such expenses and
liabilities to include, but not be limited to, judgments, court costs and
attorneys' fees and the cost of reasonable settlements, such settlements to be
approved by the Board of Directors of the Bank, if such action is brought
against Executive in his capacity as a officer or director of the Bank.
However, such indemnification shall not extend to matters as to which Executive
is finally adjudged to be liable for willful misconduct in the performance of
his duties.

The undersigned, in consideration of their mutual promises and other good and
valuable consideration, hereby agree to amend the Employment Agreement of Allen
Koranda dated April 19, 1990 (the "Agreement") by adding the following two new
sentences to the end of Section 5(a) of the Agreement:

However, notwithstanding anything contained in this section to the contrary, a
Change in Control shall not be deemed to have occurred as a result of an event
described in (i), (ii) or (iii) (a), (c) or (e) above which resulted from an
acquisition or proposed acquisition of stock of the Holding Company by a person,
as defined in the OTS' Acquisition of Control Regulations (12 C.F.R. Section
574)(the "Control Regulations"), who was an executive officer of the Holding
Company on January 19, 1990 and who has continued to serve as an executive
officer of the Holding Company as of the date of the event described in (i),
(ii) or (iii)(a), (c) or (e) above (an "incumbent officer").  In the event a
group of individuals acting in concert satisfies the definition of "person"
under the Control Regulations, the requirements of the preceding sentence shall
be satisfied, and thus a change in control shall not be deemed to have occurred,
if at least one individual in the group is an incumbent officer.

IN WITNESS WHEREOF, the parties hereto have executed this Amendment effective
this August 28, 1990.

to have commenced as of the date first above written and shall continue for a
period of sixty (60) full calendar months thereafter. Commencing on the third
anniversary date of this Agreement, and continuing at each anniversary date
thereafter, the board of directors of the Bank ("Board") may extend the
Agreement an additional year. The Board will review the Agreement and the
Executive's performance annually for purposes of determining whether to extend

The undersigned, in consideration of their mutual promises and other good and

Such amendments shall be effective as of the date shown below.

1.   Section 4(b) shall be revised to read as follows:

     times the average of the three preceding years compensation paid to the
     Executive or (B) the compensation payable to the Executive for the

     MAF Bancorp Executive Annual Incentive Plan (or such other annual cash
     incentive plan in effect with the respect to years ending prior to July 1,

     lump sum immediately upon a Change in Control and termination of employment
     of Executive or paid monthly during the thirty-six (36) months following
