(3) Pursuant to Rule 457(h)(1) under the Securities Act of 1933, as amended, the proposed maximum offering price per share and the registration fee have been estimated based on the weighted average exercise price of $13.37 for 5,865 shares of Common Stock covered by options outstanding under the plan as of April 28, 2005. INTRODUCTORY STATEMENT NOT FORMING PART OF THE PROSPECTUS This Registration Statement registers 5,865 shares of common stock of Wintrust Financial Corporation ("Wintrust") that may be issued upon exercise of outstanding stock options previously granted by First Northwest Bancorp, Inc., a Delaware corporation ("First Northwest"), under the First Northwest Bancorp, Inc. 1998 Stock Option Plan and First Northwest Bancorp, Inc. 2002 Stock Option Plan (as amended, the "Plans"). Effective March 31, 2005, Wintrust acquired First Northwest through a merger of First Northwest with and into Wintrust (the "Merger"). In connection with the Merger, each outstanding share of First Northwest common stock converted into the right to receive 0.425 shares of Wintrust common stock, or at the election of a First Northwest stockholder, 60% of such holder's shares converted into the right to receive 0.425 shares of Wintrust common stock and 40% of such holder's shares converted into cash at a value of $21.44 per share, subject to proration in accordance with the terms of the merger agreement. At the effective time of the Merger, previously granted options to purchase First Northwest common stock then outstanding under the Plans became exercisable for shares of Wintrust common stock in accordance with the terms of the Merger and the Plans. Each outstanding and unexercised stock option to purchase shares of First Northwest common stock is deemed to constitute an option to acquire, on the same terms and conditions as were applicable under the original option prior to the Merger, the number of shares of Wintrust common stock equal to the product, rounded to the nearest whole share, of the number of shares of First Northwest common stock subject to the original option and 0.425, at a price per share equal to the exercise price per share of the First Northwest common stock under the original option divided by 0.425, rounded to the nearest whole cent. 2 PART I INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS The documents containing information required by this section, which relate to the shares of common stock of Wintrust Financial Corporation ("Wintrust") being registered and remaining available for issuance pursuant to the exercise of outstanding stock options previously granted by First Northwest Bancorp. Inc. ("First Northwest") under the First Northwest Bancorp, Inc. 1998 Stock Option Plan and First Northwest Bancorp. Inc. 2002 Stock Option Plan (as amended, the "Plans"), will be given to those persons who hold outstanding options to purchase First Northwest common stock granted under the Plans, all of whom were employees or directors of First Northwest or its affiliates immediately prior to the merger of First Northwest with and into Wintrust, which was effective on March 31, 2005.

ARTICLE NINE, PARAGRAPH 1: The corporation shall indemnify, to the full extent that it shall have power under applicable law to do so and in a manner permitted by such law, any person made or threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against liabilities and expenses reasonably incurred or paid by such person in connection with such action, suit or proceeding. The corporation may indemnify, to the full extent that it shall have power under applicable law to do so and in a manner permitted by such law, any person made or threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against liabilities and expenses reasonably incurred or paid by such person in connection with such action, suit or proceeding.

Expenses incurred in defending a civil, criminal, administrative, investigative or other action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding in accordance with the provisions of Section 8.75 of the BCA. The indemnification and advancement of expenses provided by this Article shall not be deemed exclusive of any other rights to which any person indemnified may be entitled under any statute, by-law, agreement, vote of shareholders, or disinterested directors or otherwise, both as to action in his official capacity and as to action in any other capacity while holding such office, and shall continue as to a person who has ceased to be such director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such person. PARAGRAPH 2: The corporation may purchase and maintain insurance on behalf of any person referred to in the preceding paragraph against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify him or her against such liability under the provisions of this Article or otherwise. PARAGRAPH 3: For purposes of this Article, references to "the corporation" shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another 5 corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued. PARAGRAPH 4: The provisions of this Article shall be deemed to be a contract between the corporation and each director or officer who serves in any such capacity at any time while this Article and the relevant provisions of the BCA, or other applicable law, if any, are in effect, and any repeal or modification of any such law or of this Article shall not affect any rights or obligations then existing with respect to any state of facts then or theretofore existing or any action, suit or proceeding theretofore or thereafter brought or threatened based in whole or in part upon any such state of facts.

Section 6.3 of the Registrant's By-laws provides as follows: SECTION 6.3. MANDATORY INDEMNIFICATION. To the extent that a director, officer, employee or agent of a corporation, or any subsidiary or subsidiaries, as the case may be, has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 6.1 and 6.2, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him or her in connection therewith. The Illinois Business Corporation Act provides for indemnification of officers, directors, employees and agents as follows: 5/8.75 INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND AGENTS; INSURANCE. (a) A corporation may indemnify any person who was or is a party, or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the corporation or, with respect to any criminal action or proceeding, that the person had reasonable cause to believe that his or her conduct was unlawful. (b) A corporation may indemnify any person who was or is a party, or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person is or was a director, officer, 6 employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, if such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, provided that no indemnification shall be made with respect to any claim, issue, or matter as to which such person has been adjudged to have been liable to the corporation, unless, and only to the extent that the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability, but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses as the court shall deem proper. (c) To the extent that a present or former director, officer or employee of a corporation has been successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to in subsections (a) and (b), or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith if the person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation. (d) Any indemnification under subsections (a) and (b) (unless ordered by a court) shall be made by the corporation only as authorized in the specific case, upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because he or she has met the applicable standard of conduct set forth in subsections (a) or (b). Such determination shall be made with respect to a person who is a director or officer at the time of the determination: (1) by the majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, (2) by a committee of the directors designated by a majority vote of the directors, even though less than a quorum, (3) if there are no such directors, or if the directors so direct, by independent legal counsel in a written opinion, or (4) by the shareholders. (e) Expenses (including attorney's fees) incurred by an officer or director in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this Section. Such expenses (including attorneys' fees) incurred by former directors and officers or other employees and agents may be so paid on such terms and conditions, if any, as the corporation deems appropriate. (f) The indemnification and advancement of expenses provided by or granted under the other subsections of this Section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any by-law, agreement, vote of shareholders or disinterested directors, or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office. (g) A corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status as such, whether or not the corporation would have the power to indemnify such person against such liability under the provisions of this Section. (h) If a corporation indemnifies or advances expenses to a director or officer under subsection (b) of this Section, the corporation shall report the indemnification or advance in writing to the shareholders with or before the notice of the next shareholders meeting. 7 (i) For purposes of this Section, references to "the corporation" shall include, in addition to the surviving corporation, any merging corporation (including any corporation having merged with a merging corporation) absorbed in a merger which, if its separate existence had continued, would have had the power and authority to indemnify its directors, officers, and employees or agents, so that any person who was a director, officer, employee or agent of such merging corporation, or was serving at the request of such merging corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Section with respect to the surviving corporation as such person would have with respect to such merging corporation if its separate existence had continued. (j) For purposes of this Section, reference to "other enterprises" shall include employee benefit plans; references to "fines" shall include any excise taxes assessed on a person with respect to an employee benefit plan; and references to "serving at the request of the corporation" shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries. A person who acted in good faith and in a manner he or she reasonably believed to be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner "not opposed to the best interest of the corporation" as referred to in this Section. (k) The indemnification and advancement of expenses provided by or granted under this Section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee, or agent and shall inure to the benefit of the heirs, executors, and administrators of that person. (l) The changes to this Section made by this amendatory Act of the 92nd General Assembly apply only to actions commenced on or after the effective date of this amendatory Act of the 92nd General Assembly. (Last amended by P.A. 92-0033, L. '01, eff. 7-1-01.) The Registrant has purchased $30 million of insurance policies which insure its directors and officers against liability which they may incur as a result of actions taken in such capacities. In addition, the Registrant maintains fiduciary liability coverage up to a $5 million limit and trust errors and omissions coverage up to a limit of $15 million. ITEM 7.

ITEM 9. UNDERTAKINGS. (a) The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information set forth in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of the Plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless 9 in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against policy as expressed in the Act and will be governed by the final adjudication of such issue. 10 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Lake Forest, State of Illinois, on this 28th day of April, 2005.
