ITEM 11. EXECUTIVE COMPENSATION

Compensation of Directors

Directors Fees.All directors of the Company are
currently directors of the Bank.The Bank pays fees to its directors for their service as directors and as members and chairpersons of committees of the Board of Directors. Except for Director Koopmans, who receives a fee of $800 per quarter
from the Company for serving on the Companys Audit Committee, the Company does not separately compensate the members of its Board of Directors and Board committees. The fees that the Bank pays to its directors, however, are taken into account
in establishing the inter-company expense allocations that the Company pays to the Bank. Except for Mr. Gasior, who receives no fees for serving as a director, committee chairperson or committee member, the directors of the Bank receive an
annual fee of $24,000 for preparing for and attending meetings of the Board of Directors of the Bank. Members of the Executive Committee of the Bank receive an additional fee of $800 per month for performing Executive Committee functions. The
chairpersons of the Banks Audit Committee, Asset Quality Committee and Asset Liability Management Committee each receive an additional fee of $1,000 per quarter, and the other members of each of these committees receive an additional fee of
$800 per quarter, for performing committee functions. The Bank also partially reimburses Director Koopmans for his travel expenses for attending meetings of its Board of Directors.

Deferred Compensation Plan. BankFinancial, F.S.B. maintains a deferred compensation plan for the benefit of directors and certain senior
executive officers designated to participate in the plan. Participation in the plan is voluntary, and those who elect to participate in the plan do not receive any compensation beyond the compensation they would have received had they not
participated in the plan. At December 31, 2005, there was one participant in the plan. Under the plan, a participant may defer (i) any whole percentage up to 100% of his salary, bonus and/or incentive compensation, (ii) a stated
dollar amount of his bonus and/or incentive compensation, or (iii) all of his bonus and/or incentive compensation in excess of a stated dollar amount. A director may elect to defer (i) any whole percentage up to 100% of his director fees,
(ii) a stated dollar amount of his director fees, or (iii) all of his director fees in excess of a stated dollar amount. Deferrals under the plan will be credited to a deferral account for the participant. Deferral elections must be made
during the 90-day period preceding the first day of the plan year in which the salary, bonus, incentive compensation and/or director fees would otherwise be paid in cash. Individuals who become participants during a plan year may make deferral
elections with respect to future salary, director fees, bonus and incentive compensation within 30 days of becoming a participant. Participants may elect to increase, decrease or cease deferral elections with respect to future salary, director fees,
bonus and incentive compensation at any time during the plan year. Deferrals will be suspended in the event a participant receives a hardship distribution or a distribution on account of an unforeseeable emergency. For purposes of determining income
(or loss) on a participants account, a participants account will be deemed invested through a self-directed brokerage account in publicly traded mutual funds or cash as the participant may direct. A participant will be fully vested in
his or her deferral account at all times. At the participants election, benefits under the plan may be paid in a lump sum or in annual installments. In the event the balance of a participants account is less than $10,000, then
notwithstanding a participants election to the contrary, the participants account will be distributed in a lump sum. In the event the amount of any annual installment payable to a participant or beneficiary is less than $5,000, each
annual installment amount will be $5,000 until the account is exhausted or the rule governing account balances of less than $10,000 takes effect. The Bank intends to amend and restate the deferred compensation plan prior to the expiration of the
Section 409A of the Internal Revenue Code of 1986 transition period on December 31, 2006 to the extent necessary to ensure compliance with its requirements.

Executive Compensation

Summary Compensation Table.The following
table sets forth for the year ended December 31, 2005, certain information as to the total remuneration paid to our Chief Executive Officer, and to our other four most highly compensated executive officers at December 31, 2005 who received

Employment Agreements.The Bank entered into employment agreements with each of Messrs. Gasior, Brennan, Cloutier and OShaughnessy in
2003. In addition, in August 2004, following the expiration of an employment agreement that Ms. Calabrese had entered into with Success National Bank prior to its acquisition by the Company, the Bank entered into a new employment agreement with
Ms. Calabrese that is substantially similar to the employment agreements for the above four Named Executive Officers. These employment agreements were filed as Exhibits 10.3 through 10.7 to the Companys Registration Statement on Form S-1
(File Number 333-119217), originally filed with the Securities and Exchange Commission on September 23, 2004. Each employment agreement has an initial term of 36 months, and the term may be extended annually for an additional year at the
discretion of the Board of Directors so that the remaining term will be 36 months. On April 26, 2006, the Board of Directors of the Bank extended the terms of the Bank employment agreements with the five Named Executive Officers through
March 31, 2009.

Under the Bank employment agreements, the Bank will pay the Named Executive Officers the base salary reflected in the
payroll records, subject to discretionary increases by the Board of Directors. The 2006 base salary for Messrs. Gasior, Brennan, Cloutier and OShaughnessy is $395,906, $295,610, $247,046 and $252,350, respectively, and for Ms. Calabrese
the 2006 base salary is $216,300. The employment agreements provide that the base salary may be increased but not decreased. The employment agreements also provide that the Named Executive Officer is entitled to an automobile or an automobile
allowance, the payment of designated club dues and to participate with other executive officers in incentive compensation and discretionary bonuses declared by the Board. In addition to base salary and bonus, the employment agreements provide for,
among other things, participation in a Section 125 cafeteria plan, group medical, dental, vision, disability and life insurance plans, referred to as the core plans, 401(k) plan and other employee and fringe benefits applicable to executive
personnel.

During the employment period, each Named Executive Officer is provided with a supplemental disability
insurance policy that pays 60% of base salary for the remaining term of the agreement in the event the executive officer is terminated due to disability. If a Named Executive Officer becomes disabled, his or her base salary will be reduced
proportionately by the disability payments made under the disability policy and under the federal social security system. Each Named Executive Officer is responsible for paying the premiums but receives an annual allowance in an amount sufficient,
on an after-tax basis, to equal the premium payments. In the event of termination of employment due to disability, the Named Executive Officer will be entitled to his or her earned salary, the prorated annual average of any cash incentive
compensation and bonus that the executive officer received during the preceding two fiscal years, referred to as prorated incentive compensation, the prorated employer matching 401(k) plan contribution that the executive officer would be entitled to
receive for the current year, referred to as accrued plan contribution, the base salary he or she would have received from the effective date of termination through the date the employment period would have expired if his or her employment had not
sooner terminated due to disability, which will be reduced on a dollar for dollar basis by the disability insurance and federal social security disability payments referenced above, and continued coverage under the core plans through the date the
employment period would have expired, subject to the executive officers continued payment of the costs and contributions for which he or she is responsible.

In addition to the life insurance benefits provided to regular full-time employees, a supplemental life insurance policy has been provided to each insurable Named Executive Officer in an amount not less than three
times the Named Executive Officers base salary. The Named Executive Officer is the owner of the policy and receives an annual allowance sufficient to cover the cost of such insurance. In the event of an executive officers death during
the term of the employment agreement, any base salary payments required of the Bank upon the death will, assuming a supplemental life insurance policy has been obtained, be reduced on a dollar for dollar basis by the payments to the executive
officers designated beneficiary under the supplemental insurance policies. If a supplemental life insurance policy on the executives life has not been obtained, such payments will be made by the Bank in accordance with the employment
agreement. The agreements provide for termination for cause at any time. In the event of termination for cause, the Named Executive Officer will receive the unpaid balance of his or her base salary, referred to as earned salary, through the
effective date of termination of employment.

In the event the executive officers employment is terminated due to death, his or her
surviving spouse and minor children, if any, will be entitled to the same coverage under the core plans that the Named Executive Officer would have been provided if his or her employment had terminated due to disability. In addition, the Named
Executive Officers estate or trust, as applicable, will be entitled to the base salary the Named Executive Officer would have been paid through the date the employment period would have expired if the executive officers employment had
not been sooner terminated due to death. If a supplemental life insurance policy has been obtained on the life of the Named Executive Officer, the Banks obligation to make such payments will be reduced on a dollar for dollar basis by the death
benefits payments under the supplemental life insurance policy purchased for each executive officer. Except with respect to coverage under the core plans, the Bank will generally have no obligation to pay or provide a Named Executive Officers
estate, surviving spouse, or minor children with any other compensation or benefits on account of the Named Executive Officers death.

In the event the Named Executive Officers employment is terminated without cause by the Bank, the Bank will pay the Named Executive Officer his or her earned salary, prorated incentive compensation, accrued plan contribution,
continued coverage under the core plans for 36 months, subject to the executive officers payment of costs and contributions for which he or she is responsible, and an amount equal to three times his or her average annual compensation. Payment
of benefits will be made in installments over 36 months; however, the Bank has the right to elect to make a discounted lump sum payment unless the payment is deemed to be subject to Section 409A of the Internal Revenue Code, in which case such
right will not exist.

Under the employment agreements, the Named Executive Officer may terminate his or her employment for good reason by
giving notice within 60 days after the event giving rise to the right to terminate employment. Good reason generally includes our (i) decision not to re-elect or failure to re-elect the Named Executive Officer to his or her present
position; (ii) failure to extend the Named Executive Officers employment period on the anniversary date for an additional year so that the remaining term of the employment agreement will be 36 months; (iii) relocation of the Named
Executive Officers principal place of employment by more than a specified distance; (iv) reduction in

the Named Executive Officers base salary or a material reduction in benefits to which the executive officer is
entitled; (v) liquidation or dissolution of the Bank or the Company; and (vi) material uncured breach of the employment agreement. With respect to Mr. Gasiors employment agreement, good reason also includes the
failure to elect or re-elect him as chairman of the board of the Bank, a change in the composition of the board of directors of the Bank such that the current directors no longer constitute a majority of the board other than in certain circumstances
where the new board is nominated or appointed by the existing board, or a significant reduction in the scope of his duties, powers, privileges, authority or responsibilities. Mr. Gasiors employment agreement also provides that, during the
term of the employment agreement, the Board of Directors of the Bank will appoint him as the President and Chief Executive Officer of the Bank, and will appoint him as the Chairman of the Board of the Bank at all times during which he is a director
of the Bank. In the event a Named Executive Officers employment is terminated for good reason, he or she will receive the same amounts and the same coverage under the core plans that he or she would have received if his employment had been
terminated without cause. A Named Executive Officer who terminates his or her employment by resignation other than due to good reason will only be entitled to his or her earned salary through the date of termination.

The Named Executive Officer is required under the employment agreement to execute a general release in consideration for any severance amounts. The Named
Executive Officer also agrees not to compete with the Bank or its affiliates for six months after termination or during the period that severance amounts are paid, if longer. In addition, the Named Executive Officer agrees not to solicit our
customers, their business or our employees for 18 months, which may be reduced in certain circumstances. Payment of benefits under the employment agreements may be made in installments, or if the payment is not deemed to be subject to
Section 409A of the Internal Revenue Code, in a lump sum discounted to present value in the case of future cash payments, as determined by the Bank. Benefits under the Bank agreement may be reduced to avoid constituting an excess
parachute payment under Section 280G of the Internal Revenue Code of 1986, as amended.

The Bank has also entered into
employment agreements with eleven other officers, and our subsidiary Financial Assurance Services has entered into an employment agreement with one of its officers. Each such agreement has a term of 24 months and on the anniversary date thereof can
be extended for an additional 12 months so that the remaining term will be 24 months. Each such agreement contains substantially similar terms to the employment agreements described above except for the term of coverage. In addition, the failure to
extend the executive officers employment period on the anniversary date for an additional year will not constitute good reason for an executive to terminate and receive payment under the employment agreement. If the executive officer is
terminated due to disability, the Bank will pay the executive officer his or her earned salary, accrued plan contribution, base salary through the remainder of the employment period, subject to reduction for payments under the supplemental
disability insurance policy acquired pursuant to the employment agreement and for federal social security disability payments, and coverage under the core plans through the remainder of the employment period. Similarly, if the executive
officers termination is due to the executive officers death, the Bank will make the same payments to his surviving spouse and minor children, if any, including coverage under the core plans, as described above, for the remainder of the
two year employment period; however, our obligation to make continuing base salary payments will be wholly offset by the death benefit payments made under any supplemental life insurance policy that was acquired or caused to be acquired by the Bank,
or its subsidiary Financial Assurance Services, as applicable. If the executive officer is terminated without cause or in the event the executive officer voluntarily terminates for good reason, the Bank will pay the executive officer the same
compensation that would be provided in the event of termination due to disability, including continued coverage under the core plans for the remainder of the employment period. Under these employment agreements, in the event of termination for
cause, the Bank will pay the executive officer his or her earned salary through the effective date of termination of employment. We may enter into additional employment agreements in the future, depending on our growth, any acquisitions that we may
complete and promotions of our employees, among other factors. The Bank employment agreements provide the covered executives with indemnification to the maximum extent permitted under federal law.

The Company intends to enter into separate employment agreements with Messrs. Gasior, Brennan, Cloutier and OShaughnessy during 2006.The
Human Resources Committee has not finalized the form of these employment agreements. Should the Company enter into separate employment agreements with these individuals, the agreements will be filed in accordance with applicable Securities and
Exchange Commission rules and regulations.

Employee Stock Ownership Plan and Trust. The Bank implemented an employee stock ownership
plan in connection with our mutual to stock conversion, effective as of January 1, 2004. Employees with at least one year of employment with the Bank are eligible to participate. As part of the mutual to stock conversion, the employee stock
ownership plan trust borrowed funds from the Company and used those funds to purchase 1,957,300 shares of the common stock. The shares of common stock purchased by the employee stock ownership plan are the collateral for the loan. The loan will be
repaid principally from the Bank through discretionary contributions to the employee stock ownership plan over a period of up to twenty years. The loan documents provide that the loan may be repaid over a shorter period, without penalty for
prepayments. The interest rate for the loan will be equal to the prime rate plus 100 basis points, adjustable every five years. Shares purchased by the employee stock ownership plan are held in a suspense account for allocation among participants as
the loan is repaid.

Contributions to the employee stock ownership plan and shares released from the suspense account in an amount
proportional to the repayment of the employee stock ownership plan loan are allocated among employee stock ownership plan participants on the basis of compensation in the year of allocation. Benefits under the plan become fully vested upon
completion of five years of credited service, with credit given to participants for years of credited service with the Bank prior to the adoption of the plan. A participants interest in his account under the plan also fully vest in the event
of termination of service due to a participants early or normal retirement, death, disability, or upon a change in control (as defined in the plan). Vested benefits are payable in the form of shares of common stock and/or cash. The Banks
contributions to the employee stock ownership plan are discretionary, subject to the loan terms and tax law limits. Therefore, benefits payable under the employee stock ownership plan cannot be estimated. Pursuant to SOP 93-6, we are required to
record compensation expense each year in an amount equal to the fair market value of the shares released from the suspense account. We recorded compensation expenses of $718,000 for the year ended December 31, 2005 in connection with the
employee stock ownership plan, and $10,000 for the year ended December 31, 2004. The employee stock ownership plan will terminate in the event of a change in control.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

The following table sets forth, as of March 31, 2006, certain information as to the beneficial ownership of shares of the Companys common stock by: (i) those persons or entities known by the Company to
beneficially own more than 5% of the Companys outstanding shares of common stock; (ii) each director and nominee for election as director; (iii) each executive officer named in the Summary Compensation Table below; and (iv) all
directors and executive officers of the Company and the Bank as a group. The address for each person listed below is: c/o BankFinancial Corporation, 15W060 North Frontage Road, Burr Ridge, Illinois 60527. An asterisk denotes beneficial ownership of
less than one percent.
