PROXY STATEMENT

This proxy statement is furnished in connection with the solicitation of proxies by the Board of Directors of EFC Bancorp, Inc. (“EFC Bancorp” or the “Company”) to be used at the annual meeting of stockholders of the Company.  EFC Bancorp is the holding company for EFS Bank (“EFS Bank” or the “Bank”).  The annual meeting will be held at the Holiday Inn & Suites Chicago Northwest, 495 Airport Road, Elgin, Illinois on April 19, 2005 at 2:00 p.m., local time.  This proxy statement and the enclosed proxy card are being first mailed to stockholders of record on or about March 17, 2005.

General Information about Voting

Who Can Vote at the Meeting

You are entitled to vote your EFC Bancorp common stock only if the records of the Company show that you held your shares as of the close of business on March 7, 2005.  As of the close of business on March 7, 2005, a total of 4,759,513 shares of EFC Bancorp common stock were outstanding.  Each share of common stock has one vote.  The Company’s Certificate of Incorporation provides that record holders of the Company’s common stock who beneficially own, either directly or indirectly, in excess of 10% of the Company’s outstanding shares are not entitled to any vote in respect of the shares held in excess of the 10% limit.

Attending the Meeting

Your admission ticket to the annual meeting is included with this proxy statement.  If you plan to attend the meeting, please bring your admission ticket with you as you must have it in order to attend the meeting.

Vote Required

The annual meeting will be held only if there is a quorum.  A quorum exists if a majority of the outstanding shares of common stock entitled to vote is represented at the meeting.  If you return valid proxy instructions or attend the meeting in person, your shares will be counted for purposes of determining whether there is a quorum, even if you abstain from voting.  Broker non-votes also will be counted for purposes of determining the existence of a quorum.  A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner.

In voting on the election of directors, you may vote in favor of all nominees, withhold votes as to all nominees, or withhold votes as to specific nominees.  There is no cumulative voting for the election of directors.  Directors must be elected by a plurality of the votes cast at the annual meeting.  This means that the nominees receiving the greatest number of votes will be elected.  Votes that are withheld and broker non-votes will have no effect on the outcome of the election.

In voting on the ratification of the appointment of KPMG LLP as independent auditors, you may vote in favor of the proposal, vote against the proposal or abstain from voting.  The ratification of KPMG

LLP as independent auditors will be decided by the affirmative vote of a majority of the votes cast at the annual meeting.  On this matter abstentions and broker non-votes will have no effect on the voting.

Voting by Proxy

The Board of Directors of EFC Bancorp is sending you this proxy statement for the purpose of requesting that you allow your shares of EFC Bancorp common stock to be represented at the annual meeting by the persons named in the enclosed proxy card.  All shares of EFC Bancorp common stock represented at the annual meeting by properly executed and dated proxies will be voted according to the instructions indicated on the proxy card.  If you sign, date and return a proxy card without giving voting instructions, your shares will be voted as recommended by the Company’s Board of Directors.  The Board of Directors recommends a vote “FOR” each of the nominees for director and “FOR” ratification of KPMG LLP as independent auditors.

If any matters not described in this proxy statement are properly presented at the annual meeting, the persons named in the proxy card will use their own best judgment to determine how to vote your shares.  This includes a motion to adjourn or postpone the annual meeting in order to solicit additional proxies.  If the annual meeting is postponed or adjourned, your EFC Bancorp common stock may be voted by the persons named in the proxy card on the new annual meeting date as well, unless you have revoked your proxy.  The Company does not know of any other matters to be presented at the annual meeting.

You may revoke your proxy at any time before the vote is taken at the meeting.  To revoke your proxy you must either advise the Corporate Secretary of the Company in writing before your common stock has been voted at the annual meeting, deliver a later dated proxy, or attend the meeting and vote your shares in person.  Attendance at the annual meeting will not in itself constitute revocation of your proxy.

If your EFC Bancorp common stock is held in “street name,” you will receive instructions from your broker, bank or other nominee that you must follow in order to have your shares voted.  Your broker, bank or other nominee may allow you to deliver your voting instructions via the telephone or the Internet.  Please see the instruction form provided by your broker, bank or other nominee that accompanies this proxy statement.

Proxies solicited are to be returned to the Company’s transfer agent, LaSalle Bank, N.A.  The Board of Directors has designated LaSalle to act as inspectors of election, and tabulate the votes at the annual meeting.  LaSalle is not otherwise employed by, or a director of the Company or any of its affiliates.  After the final adjournment of the annual meeting, the proxies will be returned to the Company.

Participants in the Bank’s ESOP or 401(k) Plan

If you participate in the EFS Bank Employee Stock Ownership Plan (the “ESOP”) or if you hold shares through the Elgin Financial Center, SB 401(k) Employee Benefit Plan & Trust (the “401(k) Plan”), you will receive a voting instruction form for each plan that reflects all shares you may direct the trustees to vote on your behalf under the plans.  Under the terms of the ESOP, the ESOP trustee votes all shares held by the ESOP, but each ESOP participant may direct the trustee how to vote the shares of common stock allocated to his or her account.  The ESOP trustee, subject to the exercise of its fiduciary duties, will vote all unallocated shares of Company common stock held by the ESOP and

2

allocated shares for which no voting instructions are received in the same proportion as shares for which it has received timely voting instructions.  Under the terms of the 401(k) Plan, a participant is entitled to direct the trustee as to the shares in the EFC Bancorp, Inc. Stock Fund credited to his or her account.  The trustee will vote all shares for which no directions are given or for which instructions were not timely received in the same proportion as shares for which the trustee received voting instructions.  The deadline for returning your voting instructions to each plan’s trustee is April 11, 2005.

If the ratification of the appointment of the independent auditors is not approved by a majority of the votes cast by stockholders at the annual meeting, the Audit Committee will consider other independent auditors.

The Board of Directors recommends that stockholders vote “FOR” the ratification of the appointment of independent auditors.

Audit Fees

The following table sets forth the fees billed to the Company for the fiscal years ending December 31, 2004 and 2003 by KPMG LLP:

(1)   Consists of tax filing and tax related compliance and other advisory services.

The Audit Committee believes that the provision of non-audit services by KPMG LLP are compatible with maintaining KPMG LLP’s independence.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Auditor

The Audit Committee is responsible for appointing, setting compensation, and overseeing the work of the independent auditor.  In accordance with its charter, the Audit Committee approves, in advance, all audit and permissible non-audit services to be performed by the independent auditor.  Such approval process ensures that the external auditor does not provide any non-audit services to the Company that are prohibited by law or regulation.

In addition, the Audit Committee has established a policy regarding pre-approval of all audit and permissible non-audit services provided by the independent auditor.  Requests for services by the independent auditor for compliance with the auditor services policy must be specific as to the particular services to be provided.  The request is initially forwarded for review to a group whose members consist of the Company’s President, Chief Executive Officer and Chief Financial Officer.  Requests approved by the group are aggregated and submitted to the Audit Committee for approval.

10

The request may be made with respect to either specific services or a type of service for predictable or recurring services.

During the year ended December 31, 2004, all services were approved, in advance, by the Audit Committee in compliance with these procedures.

Report of the Audit Committee

The Audit Committee of the Company’s Board of Directors is comprised of four non-employee directors and operates under a written charter adopted by the Board of Directors.  The Board of Directors has determined that the Audit Committee members are independent in accordance with the listing standards of the American Stock Exchange.

The Company’s management is responsible for the Company’s internal controls and financial reporting process.  The independent auditors are responsible for performing an independent audit of the Company’s consolidated financial statements and issuing an opinion on the conformity of those financial statements with generally accepted accounting principles.  The Audit Committee oversees the Company’s internal controls and financial reporting process on behalf of the Board of Directors.

In this context, the Audit Committee has met and held discussions with management and the independent auditors.  Management represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with generally accepted accounting principles, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent auditors.  The Audit Committee discussed with the independent auditors matters required to be discussed by Statement on Auditing Standards No. 61 (Communication With Audit Committees), including the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of the disclosures in the financial statements.

In addition, the Audit Committee has received the written disclosures and the letter from the independent auditors required by the Independence Standards Board Standard No. 1 (Independence Discussions With Audit Committees) and has discussed with the independent auditors the auditors’ independence from the Company and its management.  In concluding that the auditors are independent, the Audit Committee considered, among other factors, whether the non-audit services provided by the auditors were compatible with its independence.

The Audit Committee discussed with the Company’s independent auditors the overall scope and plans for their audit.  The Audit Committee meets with the independent auditors, with and without management present, to discuss the results of their audit, their evaluation of the Company’s internal controls, and the overall quality of the Company’s financial reporting process.

In performing all of these functions, the Audit Committee acts only in an oversight capacity.  In its oversight role, the Audit Committee relies on the work and assurances of the Company’s management, which has the primary responsibility for financial statements and reports, and of the independent auditors who, in their report, express an opinion on the conformity of the Company’s financial statements to generally accepted accounting principles.  The Audit Committee’s oversight does not provide it with an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or policies, or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit

11

Committee’s considerations and discussions with management and the independent auditors do not assure that the Company’s financial statements are presented in accordance with generally accepted accounting principles, that the audit of the Company’s financial statements has been carried out in accordance with generally accepted auditing standards or that the Company’s independent auditors are in fact “independent.”

In reliance on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the board has approved, that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004 for filing with the Securities and Exchange Commission.  The Audit Committee and the Board of Directors also have approved, subject to stockholder ratification, the selection of the Company’s independent auditors.

In order for the executive to realize the potential values set forth in the 5% and 10% columns in the table, the price per share of EFC Bancorp’s common stock as of the expiration date of the options would be approximately $42.76 per share and $68.09 per share, respectively, with respect to the options having an exercise price of $26.25 per share and approximately $40.56 per share and $64.59 per share, respectively, with respect to the options having an exercise price of $24.90 per share.

(2)   Options become exercisable in five equal annual installments commencing on January 21, 2005; provided, however, that options will be immediately exercisable if the optionee dies or becomes disabled or upon a change in control of EFC Bancorp, Inc., as defined in the plan.

(3)   Options become exercisable in five equal annual installments commencing on December 21, 2005; provided, however, that options will be immediately exercisable if the optionee dies or becomes disabled or upon a change in control of EFC Bancorp, Inc., as defined in the plan.

Employment Agreements

Employment Agreements.  The Company and Bank currently maintain three-year employment agreements with Messrs.  O’Connor and Kovac.  The terms of the Company employment agreements are extended on a daily basis unless written notice of non-renewal is given by the Board of Directors and the terms of the Bank employment agreements are renewable on an annual basis.  The employment agreements provide that the executive’s base salary will be reviewed at least annually.  The base salaries which are currently effective for the employment agreements for Messrs.  O’Connor and Kovac are $245,000 and $220,800, respectively.  In addition to the base salary, the employment agreements provide for, among other things, participation in stock benefits plans and other fringe benefits applicable to executive personnel.

The employment agreements provide for termination by the Company and Bank for cause, as described in the employment agreements, at any time.  If the Company or Bank chooses to terminate the executive’s employment for reasons other than for cause, or if the executive resigns from the Company or Bank after specified circumstances that would constitute constructive termination, the executive or, if the executive dies, his beneficiary, would be entitled to receive an amount equal to the base salary and bonus payments that would have been paid to the executive for the remaining term of the employment agreement and the contributions that would have been made on the executive’s behalf to any employee benefit plans of the Company and Bank during the remaining term of the employment agreement.  The Company and Bank would also continue the executive’s life, health, medical, dental and disability coverage for the remaining term of the employment agreement.  Upon termination of the executive for reasons other than a change in control, the executive must comply with a one year non-competition agreement.

Under the employment agreements, if voluntary or involuntary termination follows a change in control of the Company or Bank (as described in the agreements), the executive or, if the executive dies, his beneficiary, would be generally entitled to a severance payment equal to three times the highest taxable year’s annual compensation and the last three calendar years.  The Company and Bank would also continue the executive’s life, health, and disability coverage for thirty-six months.  Even though both the Company and Bank employment agreements provide for a severance payment if a change in control occurs, the executive would not receive duplicative payments or benefits under the agreements.  The executive would also be entitled to receive an additional tax indemnification payment if payments under the employment agreements or otherwise triggered liability under the Internal Revenue Code for the excise tax applicable to “excess parachute payments.”  Under applicable law, the excise tax is triggered by change in control-related payments that equal or exceed three times the executive’s average annual compensation over the five years preceding the change in control.  The excise tax equals 20% of the amount of the payment in excess of one times the executive’s average compensation over the preceding five-year period.

Management Supplemental Executive Retirement Plan.  The Bank maintains the Management Supplemental Executive Retirement Plan (“Management SERP”) to provide certain officers and highly compensated employees, designated by the Board of Directors, with additional retirement and change in control benefits.  The Management SERP benefit is intended to make up benefits lost under the ESOP allocation procedures to participants who retire or are terminated in connection with a change in control prior to the complete repayment of the ESOP loan.  Management SERP benefits are determined by first:  (1) projecting the number of shares that would have been allocated to the participant under the ESOP if they had been employed throughout the period of the ESOP loan (measured from the participant’s first date of ESOP participation); and (2) reducing that number by the number of shares

16

actually allocated to the participant’s account under the ESOP; and second, by multiplying the number of shares that represent the difference between these figures by the average fair market value of the common stock over the preceding five years.  Benefits under the Management SERP vest in 20% annual increments over a five-year period commencing as of the date of a participant’s participation in the Management SERP.  The vested portion of the Management SERP participant’s benefits are payable upon the retirement of the participant upon or after the attainment of age 65 or upon termination in connection with a change in control.  The Board of Directors of the Bank has designated Messrs.  O’Connor and Kovac as Management SERP participants.

Supplemental Executive Retirement Plan.  During 2002, the Bank entered into supplemental executive retirement agreements with certain executive officers, including each of the named executive officers.  The supplemental agreements are intended to provide each of the executives with a supplemental benefit following their termination of employment.  Under the agreements, each of the executives will receive an annual benefit for a period of 15 years following the executive’s termination of employment on or after attaining age 65.  The annual normal retirement benefits, subject to subsequent increases by the board of directors at its discretion, for Messrs.  O’Connor, Kovac, Reining, Blackburn and Stanczak equal $64,300, $76,500, $53,900, $36,000 and $26,900, respectively. The agreements also provide each of the executives with an annual benefit that may be reduced in the event they terminate employment or become disabled prior to attaining age 65, depending on the number of years of service they have completed with the Bank.  Upon a change in control, each of the executives becomes entitled to 100% of his or her normal annual benefit.  Upon an executive’s death, the beneficiary of each executive becomes entitled to the benefit to which the executive would have been entitled at the time of death, unless the executive dies while in active service with the Bank.  In that case, the executive’s beneficiary becomes entitled to 100% of the normal benefit that would have been paid had the executive terminated employment after attaining age 65.

Compensation Committee Report on Executive Compensation

The following is a report of the Compensation Committee of the Board of Directors regarding executive compensation.  The Compensation Committee’s membership and duties are described on page 4.

Compensation Policies

Compensation Policies.  The policies and objectives of the Compensation Committee are designed to assist the Company in attracting and retaining qualified executives, to recognize individual contributions toward achieving strategic business initiatives and reward them for their achievement and to closely align the financial interests of the executive officers with those of its shareholders.  In furtherance of these objectives, the Company and Bank maintain a compensation program for executive officers which consists of both cash and equity based compensation.

The Compensation Committee, all of whom are independent Board members, determine the compensation for the Chairman of the Board, Chief Executive Officer and President, generally based upon a review of their performance during the prior year and competitive data for that position.  For compensation of executive officers, other than themselves, the Chief Executive Officer and the President make recommendations to the Compensation Committee for the compensation of all executive officers of the Bank.  In this process, the officers are evaluated as to their performance during the year and compared to the Bank’s performance and thrift industry compensation surveys for comparable positions at other thrift institutions.  The Compensation Committee generally follows management’s recommendations.

The compensation package available to executive officers is composed of the following components:

(1)           base salary;

(2)           annual cash incentive awards; and

(3)           long term incentive compensation, including option and stock awards.

Components of Executive Compensation

Base Salaries.  Salary levels are intended to be consistent and competitive with the practices of other comparable financial institutions and each executive’s level of responsibility.  The Compensation Committee utilized the “2004 America’s Community Bankers Compensation Survey” in determining the compensation paid to executive officers performing similar duties for depository institutions and their holding companies with particular focus on the level of compensation paid by comparable institutions in the $500 million to $1 billion asset size in the Midwest Region which includes Illinois, Indiana, Iowa, Michigan, Missouri and Wisconsin.

Although the Compensation Committee’s recommendations are discretionary and no specific formula is used for decision making, salary increases are aimed at reflecting the overall performance of the Company and the performance of the individual executive officer.

18

Annual Cash Incentive Awards.  As discussed under “Base Salaries,” cash incentive awards are intended to be consistent with comparative practices of other comparable financial institutions and each executive officer’s level of responsibility, as reported in the “2004 America’s Community Bankers Compensation Survey.”  Such awards are based on achieving performance related goals by each executive officer during the year.

Long Term Incentive Compensation.  The Company maintains the EFC Bancorp, Inc. 1998 Stock-Based Incentive Plan and the Stock Option Plan and the EFC Bancorp, Inc. 2000 Stock Option Plan under which executive officers may receive grants and awards of common stock and options to purchase common stock of the Company.  The Compensation Committee believes that stock ownership is a significant incentive in building shareholder value and aligning the interests of employees with shareholders.  The value of this component of compensation increases as the common stock of the Company appreciates in value.

Barrett J. O’Connor - Chief Executive Officer Compensation.  The base salary of Barrett J. O’Connor as the Chief Executive Officer for fiscal year 2004 was $245,000.  This salary is in line with similar-sized public thrifts in Illinois as reported by the “2004 America’s Community Bankers Compensation Survey.”  The Compensation Committee did not authorize a 2004 cash incentive award to Barrett J. O’Connor.

Other Information Relating to Directors and Executive Officers

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s executive officers and directors, and persons who own more than 10% of any registered class of the Company’s equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission.  Executive officers, directors and greater than 10% stockholders are required by regulation to furnish the Company with copies of all Section 16(a) reports they file.

Based solely on the Company’s review of copies of the reports it has received and written representations provided to it from the individuals required to file the reports, the Company believes that each of its executive officers and directors has complied with applicable reporting requirements for transactions in EFC Bancorp common stock during the year ended December 31, 2004, except that Messrs.  Brittain, Fernandez, Narum and Wedeen each failed to report a transaction on a Form 4 in a timely manner due to administrative error and Mr. Wedeen failed to report a transaction on a Form 3 in a timely manner due to administrative error.

Transactions with Management

The Sarbanes-Oxley Act of 2002 generally prohibits loans by the Company to its executive officers and directors.  However, the Sarbanes-Oxley Act contains a specific exemption from such prohibition for loans by EFS Bank to its executive officers and directors in compliance with federal banking regulations.  Federal regulations require that all loans or extensions of credit to executive officers and directors must generally be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons, unless the loan or extension of credit is made under a benefit program generally available to all other employees and does not give preference to any insider over any other employee, and must not involve more than the normal risk of repayment or present other unfavorable features.  EFS Bank currently makes new loans and extensions of credit to EFS Bank’s executive officers, directors and employees at different rates than those offered to the general public; however, EFS Bank does not give preference to any director or officer over any other employee, and such loans do not involve more than the normal risk of repayment or present other unfavorable features.

The Bank offers directors, officers and full-time employees of the Bank who satisfy certain criteria and the general underwriting standards of the Bank, adjustable-rate mortgage loans with interest rates which may be up to 1% below the rates offered to the Bank’s other customers.  This program is called the Employee Mortgage Rate (“EMR”).  The EMR is limited to the purchase or refinance of a director’s, officer’s or employee’s owner-occupied primary residence.  Loan application fees are waived for all EMR loans.  The EMR normally ceases upon termination of employment.  Upon termination of the EMR, the interest rate reverts to the contract rate in effect at the time that the loan was originated.  All other terms and conditions contained in the original mortgage and note continue to remain in effect.  With the exception of EMR loans, the Bank currently makes loans to its executive officers, directors and employees on the same terms and conditions offered to the general public.  Set forth below is certain information with respect to the EMR loans made by the Bank to executive officers or directors of the Bank or the Company and their affiliates which in the aggregate exceeded $60,000 at any time since January 1, 2004.

Mr. Kerry O’Connor, brother of Mr. Barrett J. O’Connor, is a partner of Symmetry Group LLC, which received payment in the amount of $193,754 for building construction work on EFS Bank’s buildings and he is also owner of Executive Property Maintenance which received payment in the amount of $30,830 for building cleaning services of EFS Bank’s buildings.

Governance/Nominating Committee Procedures

General

It is the policy of the Governance/Nominating Committee of the Board of Directors of Company to consider director candidates recommended by shareholders who appear to be qualified to serve on the Company’s Board of Directors.  The Governance/Nominating Committee may choose not to consider an unsolicited recommendation if no vacancy exists on the Board of Directors and the Governance/Nominating Committee does not perceive a need to increase the size of the Board of Directors.  In order to avoid the unnecessary use of the Governance/Nominating Committee’s resources, the Governance/Nominating Committee will consider only those director candidates recommended in accordance with the procedures set forth below.

Procedures to be Followed by Stockholders

To submit a recommendation of a director candidate to the Governance/Nominating Committee, a shareholder should submit the following information in writing, addressed to the Chairman of the Governance/Nominating Committee, care of the Corporate Secretary, at the main office of the Company:

1.             The name of the person recommended as a director candidate;

2.             All information relating to such person that is required to be disclosed in solicitations of proxies for election of directors pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended;

3.             The written consent of the person being recommended as a director candidate to being named in the proxy statement as a nominee and to serving as a director if elected;

4.             As to the shareholder making the recommendation, the name and address, as they appear on the Company’s books, of such shareholder; provided, however, that if the shareholder is not a registered holder of the Company’s common stock, the shareholder should

22

submit his or her name and address along with a current written statement from the record holder of the shares that reflects ownership of the Company’s common stock; and

5.             A statement disclosing whether such shareholder is acting with or on behalf of any other person and, if applicable, the identity of such person.

In order for a director candidate to be considered for nomination at the Company’s annual meeting of shareholders, the recommendation must be received by the Governance/Nominating Committee at least 120 calendar days prior to the date the Company’s proxy statement was released to shareholders in connection with the previous year’s annual meeting, advanced by one year.

Minimum Qualifications

The Governance/Nominating Committee has adopted a set of criteria that it considers when it selects individuals to be nominated for election to the Board of Directors.  First a candidate must meet the eligibility requirements set forth in the Company’s bylaws, which include a residency requirement, an age limitation and a requirement that the candidate not have been subject to certain criminal or regulatory actions.  A candidate also must meet any qualification requirements set forth in any Board or committee governing documents.

The Governance/Nominating Committee will consider the following criteria in selecting nominees: financial, regulatory and business experience; familiarity with and participation in the local community; integrity, honesty and reputation; dedication to the Company and its stockholders; independence; and any other factors the Governance/Nominating Committee deems relevant, including age, diversity, size of the Board of Directors and regulatory disclosure obligations.

In addition, prior to nominating an existing director for re-election to the Board of Directors, the Governance/Nominating Committee will consider and review an existing director’s Board and committee attendance and performance; length of Board service; experience, skills and contributions that the existing director brings to the Board; and independence.

Process for Identifying and Evaluating Nominees

The Governance/Nominating Committee process that it follows when it identifies and evaluates individuals to be nominated for election to the Board of Directors is as follows:

Identification.  For purposes of identifying nominees for the Board of Directors, the Governance/Nominating Committee relies on personal contacts of the committee and other members of the Board of Directors as well as its knowledge of members of EFS Bank’s local communities.  The Governance/Nominating Committee will also consider director candidates recommended by shareholders in accordance with the policy and procedures set forth above.  The Governance/Nominating Committee has not previously used an independent search firm in identifying nominees.

Evaluation.  In evaluating potential nominees, the Governance/Nominating Committee determines whether the candidate is eligible and qualified for service on the Board of Directors by evaluating the candidate under the selection criteria set forth above.  In addition, the Governance/Nominating Committee will conduct a check of the individual’s background and interview the candidate.

23

Submission of Business Proposals and Stockholder Nominations

The Company must receive proposals that stockholders seek to include in the proxy statement for the Company’s next annual meeting no later than November 17, 2005.  If next year’s annual meeting is held on a date more than 30 calendar days from April 19, 2006, a stockholder proposal must be received by a reasonable time before the Company begins to print and mail its proxy solicitation for such annual meeting.  Any stockholder proposals will be subject to the requirements of the proxy rules adopted by the Securities and Exchange Commission.

The Company’s Bylaws provides that in order for a stockholder to make nominations for the election of directors or proposals for business to be brought before the annual meeting, a stockholder must deliver notice of such nominations and/or proposals to the Secretary not less than 90 nor more than 120 days prior to the date of the annual meeting; provided that if less than 100 days’ notice or prior public disclosure of the date of the annual meeting is given to stockholders, such notice must be received not later than the close of the 10^th day following the day on which notice of the date of the annual meeting was mailed to stockholders or prior public disclosure of the meeting date was made.  A copy of the Bylaws may be obtained from the Company.

Miscellaneous

The Company’s Annual Report to Stockholders has been mailed to persons who were stockholders as of the close of business on March 7, 2005.  Any stockholder who has not received a copy of the Annual Report may obtain a copy by writing to the Corporate Secretary of the Company.  The Annual Report is not to be treated as part of the proxy solicitation material or as having been incorporated in this proxy statement by reference.

A copy of the Company’s Annual Report on Form 10-K, without exhibits, for the year ended December 31, 2004, as filed with the Securities and Exchange Commission, will be furnished without charge to persons who were stockholders as of the close of business on March 7, 2005 upon written request to Jerry L. Gosse, EFC Bancorp, Inc., 1695 Larkin Avenue, Elgin, Illinois 60123.

If you and others who share your address own your shares in street name, your broker or other holder of record may be sending only one annual report and proxy statement to your address.  This practice, known as “householding,” is designed to reduce our printing and postage costs.  However, if a shareholder residing at such an address wishes to receive a separate annual report or proxy statement in the future, he or she should contact the broker or other holder of record.  If you own your shares in street name and are receiving multiple copies of our annual report and proxy statement, you can request householding by contacting your broker or other holder of record.
