The purpose or purposes for which a special meeting is called shall be specified in the notice of meeting given

To be timely, a call by a One Fifth Holder must be delivered or mailed and received at the principal office of the corporation not later than the close of business on the 90th day, and not earlier than the close of business on the 120th day, before the date of the special meeting being called.

SECTION 3. MEETINGS - GENERAL. (a) Only such persons who are nominated in accordance with the procedures set forth in this Article II (or in Article III, Section 8) shall be eligible to be elected as directors at a meeting of shareholders and only such business shall be conducted at a meeting of shareholders as shall have been brought before the meeting in accordance with the applicable procedures set forth in this Article II. The presiding officer of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the

meeting was made, or proposed, as the case may be, in accordance with the procedures set forth in this Article II and, if such presiding officer determines that any proposed nomination or business is not in compliance with this Article II, to declare that such defective nomination or proposal shall be disregarded and any such nomination or business not properly brought before the meeting shall not be transacted.

(b) For purposes of this Article II, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press, Reuters or comparable national news service or in a document publicly filed by the corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act, and “group” shall have the meaning ascribed to such term under Section 13(d)(3) of the Exchange Act and the rules and regulations thereunder.

(c) Notwithstanding the foregoing provisions of this Article II, a shareholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Article II. The requirements of this Article II shall apply to all shareholder nominations and all shareholder proposals to be considered at a meeting of shareholders, whether or not such nominations or proposals are sought to be included in the corporation’s proxy statement; provided, however, that nothing in this Article II shall be deemed to affect any rights of (x) shareholders to request inclusion of proposals in the corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act, or (y) the holders of any series of Preferred Stock to elect directors under specified circumstances. The foregoing notice requirements of this Article II shall be deemed satisfied with respect to a shareholder proposal if the shareholder has notified the corporation of the shareholder’s intention to present such proposal at an annual meeting in compliance with Rule 14a-8 promulgated under the Exchange Act and such shareholder’s proposal has been included in a proxy statement that has been prepared by the corporation to solicit proxies for such annual meeting. The provisions of this Article II shall also govern what constitutes timely notice for purposes of Rule 14a-4(c) of the Exchange Act.

SECTION 4. PLACE OF MEETING. The board of directors may designate any place, either within or without the State of Illinois, as the place of meeting for any annual meeting or for any special meeting called by the board of directors. If no designation is made, or if a special meeting be otherwise called, the place of meeting shall be the principal office of the corporation in the State of Illinois.

SECTION 5. NOTICE OF MEETINGS. Written notice stating the place, day and hour of the meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be delivered not less than ten nor more than sixty days before the date of the meeting, or in the case of a merger, consolidation, share exchange, dissolution or sale, lease or exchange of assets, not less than twenty days nor more than sixty days before the date of the meeting, either personally or by mail, by or at the direction of the chairman of the board, or the secretary, or in the event that a special meeting has been properly called by a One Fifth Holder in accordance with Section 2 of this Article II, and notice of such meeting has not been given by the

secretary within 65 days after the call of such meeting, notice thereof shall be given between the 66th and the 75th day after such call by the persons calling the meeting, to each shareholder of record entitled to vote at such meeting. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail, addressed to the shareholder at his address as it appears on the records of the corporation, with postage thereon prepaid.

SECTION 6. FIXING OF RECORD DATE. For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders, or shareholders entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other proper purpose, the board of directors of the corporation may fix in advance a date as the record date for any such determination of shareholders, such date in any case to be not more than sixty days and, in case of a meeting of shareholders, not less than ten days, or in the case of a merger, consolidation, share exchange, dissolution or sale, lease or exchange of assets, not less than twenty days, prior to the date on which the particular action, requiring such determination of shareholders, is to be taken. If no record date is fixed for the determination of shareholders entitled to notice of or entitled to vote at a meeting of shareholders, or entitled to receive payment of a dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the board of directors declaring such dividend is adopted, as the case may be, shall be the record date for such determination of shareholders. When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided above, such determination shall apply to any adjournment thereof.

SECTION 7. VOTING LISTS. The officer or agent having charge of the transfer books for shares of the corporation shall make within twenty days after the record date for a meeting of shareholders, or ten days before such meeting of shareholders, whichever is earlier, a complete list of the shareholders entitled to vote at such meeting, arranged in alphabetical order, with the address of and the number of shares held by each, which list, for a period of ten days prior to such meeting, shall be kept on file at the principal office of the corporation in the State of Illinois and shall be subject to inspection by any shareholder at any time during usual business hours and to copying at the shareholder’s expense. Such list shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any shareholder during the whole time of the meeting. The original share ledger or transfer book, or a duplicate thereof kept in the State, shall be prima facie evidence as to who are the shareholders entitled to examine such list or share ledger, or transfer book or to vote at any meeting of shareholders.

SECTION 8. QUORUM. A majority of the outstanding shares of the corporation, entitled to vote on a matter, represented in person or by proxy, shall constitute a quorum at any meeting of shareholders.

When any meeting is convened, the presiding officer, if directed by the Board, may adjourn the meeting without a vote of shareholders if (a) no quorum is present for the

transaction of business, or (b) the Board determines that adjournment is necessary or appropriate to enable the shareholders (1) to consider fully information which the Board determines has not been made sufficiently or timely available to shareholders, or (2) otherwise to exercise effectively their voting rights. At any such adjourned meeting at which there is a quorum, any business may be transacted that might have been transacted at the meeting originally called.

SECTION 9. PROXIES. A shareholder may appoint a proxy to vote or otherwise act for the shareholder by delivering a valid appointment to the person so appointed or such person’s agent; provided that no shareholder may name more than three persons as proxies to attend and to vote the shareholder’s shares at any meeting of shareholders.

SECTION 11. VOTING OF SHARES BY CERTAIN HOLDERS. Shares standing in the name of another corporation, domestic or foreign, may be voted by such officer, agent, or proxy as the by-laws of such corporation may prescribe, or, in the absence of such provision, as the board of directors of such corporation may determine.

Shares standing in the name of a deceased person may be voted by his administrator or executor, either in person or by proxy. Shares standing in the name of a guardian, conservator, or trustee may be voted by such fiduciary, either in person or by proxy, but no guardian, conservator, or trustee shall be entitled, as such fiduciary, to vote shares held by him without a transfer of such shares into his name.

Shares standing in the name of a receiver may be voted by such receiver, and shares held by or under the control of a receiver may be voted by such receiver without the transfer thereof into his name if authority to do so be contained in an appropriate order of the court by which such receiver was appointed.

A shareholder whose shares are pledged shall be entitled to vote such shares until the shares have been transferred into the name of the pledgee, and thereafter the pledgee shall be entitled to vote the shares so transferred.

Shares of its own stock belonging to this corporation shall not be voted, directly or indirectly, at any meeting and shall not be counted in determining the total number of outstanding shares at any given time, but shares of its own stock held by it in a fiduciary capacity may be voted and shall be counted in determining the total number of outstanding shares at any given time.

SECTION 12. CUMULATIVE VOTING. In all elections for directors, every shareholder shall have the right to vote, in person or by proxy, the number of shares owned by him, for as many persons as there are directors to be elected, or to cumulate said shares, and give one candidate as many votes as the number of directors multiplied by the number of his shares shall equal, or to distribute them on the same principle among as many candidates as he shall see fit.

SECTION 13. VOTING BY BALLOT. Voting on any question or in any election may be by voice, unless the officer or other person presiding over the meeting shall order or any shareholder shall demand that voting be by ballot.

SECTION 14. PRESIDING OFFICERS AND ORDER OF BUSINESS. All meetings of shareholders shall be called to order and presided over by the chairman of the board, or in his absence, by the lead director or by another director designated by the board, or in the absence of such designated director or if no such designation has been made, by the senior chairman of the board, if any. The secretary of the corporation shall act as secretary of the meeting, but in the absence of the secretary of the corporation, the presiding officer may appoint a secretary of the meeting.

SECTION 15. PROCEDURAL MATTERS. At each meeting of shareholders, the presiding officer shall fix and announce the date and time of the opening and the closing of the polls for each matter upon which the shareholders will vote at the meeting and shall determine the order of business and all other matters of procedure. Except to the extent inconsistent with any such rules and regulations as adopted by the Board, the presiding officer may establish rules, which need not be in writing, to maintain order for the conduct of the meeting, including, without limitation, restricting attendance to bona fide shareholders of record and their proxies and other persons in attendance at the invitation of the presiding officer and making rules governing speeches and debates. The presiding officer acts in his or her absolute discretion and his or her rulings are not subject to appeal.

(b) The consent shall be evidenced by one or more written approvals, each of which sets forth the action taken and bears the signature of one or more directors. All the approvals evidencing the consent shall be delivered to the secretary to be filed in the corporate records.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

SECTION 1. The corporation shall 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 is or was a

director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer 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 him in connection with such action, suit or proceeding, if he acted in good faith and in a manner he 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 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 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 reasonable cause to believe that his conduct was unlawful.

SECTION 2. The corporation shall 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 by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonably incurred by him in connection with the defense or settlement of such action, suit or proceeding, if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to the best interests of the corporation, and except that no indemnification shall be made with respect to any claim, issue or matter as to which such person has been finally adjudged to have been liable to the corporation, unless, and only to the extent that the court in which such action, suit or proceeding 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.

SECTION 3. (a) Any indemnification under Sections 1 or 2 (unless ordered by a court) shall be made only as authorized in the specific case, upon a determination that indemnification of the director or officer is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 1 or 2. Such determination shall be made: (i) if a change in control shall have occurred, by independent legal counsel in a written opinion to the board of directors, a copy of which shall be delivered to the claimant; or (ii) if a change in control shall not have occurred: (A) by a majority vote of directors who were not parties to such action, suit or proceeding, even though less than a quorum, (B) by a committee of directors who were not parties to such action, suit or proceeding, even though less than a quorum, designated by a majority vote of the directors, (C) if there are no such directors who were not parties to such action, suit or proceeding, or if such directors so direct, by independent legal counsel in a written opinion, or (D) by the shareholders.

(b) In any event, to the extent that a present or former director or officer of the corporation has been successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to in Sections 1 or 2 or in defense of any claim, issue or matter therein, he shall be indemnified against reasonable expenses (including attorneys’ fees) actually and reasonably incurred by him in connection therewith, if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation.

(c) In the event the determination of entitlement to indemnification is to be made by independent legal counsel pursuant to subsection 3(a) hereof, the independent legal counsel shall be selected as provided in this subsection 3(c). If a change in control shall not have occurred, the independent legal counsel shall be selected by the board of directors, and the corporation shall give written notice to the claimant advising him of the identity of the independent legal counsel so selected. If a change in control shall have occurred, the independent legal counsel shall be selected by the claimant (unless the claimant shall request that such selection be made by the board of directors, in which event the preceding sentence shall apply) and the claimant shall give written notice to the corporation advising it of the identity of the independent legal counsel so selected.

SECTION 4. (a) Reasonable expenses (including attorney’s fees) incurred by an director or officer in defending a civil or criminal action, suit or proceeding shall be paid by the corporation in advance of the final disposition of such action, suit or proceeding, upon receipt of (i) a statement signed by such director or officer to the effect that such director or officer acted in good faith and in a manner which he believed to be in, or not opposed to the best interests of the corporation and (ii) an undertaking by or on behalf of the director or officer to repay such amount, if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized in this Article XII.

(b) The board of directors may, by separate resolution adopted under and referring to this Article XII of the by-laws, provide for securing the payment of authorized advances by the creation of escrow accounts, the establishment of letters of credit or such other means as the board deems appropriate and with such restrictions, limitations and qualifications with respect thereto as the board deems appropriate in the circumstances.

SECTION 5. (a) The corporation is specifically authorized to enter into agreements with any of its directors or officers extending rights to indemnification and advancement of expenses to such person to the fullest extent permitted by law. The indemnification and advancement of expenses provided by or granted under this Article XII shall be separate and distinct from and shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any statute, by-law, agreement, including, without limitation, indemnification agreements entered into between the corporation and any director or officer thereof, vote of shareholders or disinterested directors, or otherwise, both as to

action in his official capacity and as to action in another capacity while holding such office. To the extent that there is a conflict or inconsistency between this Article XII, the corporation’s articles of incorporation and any indemnification agreement between the corporation and any of its directors or officers, it is the intent that the director and/or officer shall enjoy the greater benefits regardless of whether contained herein, in the articles of incorporation or in such indemnification agreement.

(b) The provisions of this Article XII shall be deemed to be a contract between the corporation and each director and officer who serves in such capacity at any time while this Article XII is in effect and all rights under this Article XII including with respect to indemnification and advancement of expenses shall immediately and fully vest at the time a person first becomes a director or officer, shall remain vested as to a person who has ceased to be a director or officer and shall inure to the benefit of the heirs, executors and administrators of such a person, and such rights cannot be terminated or diminished in scope by the corporation, the board of directors or the shareholders of the corporation with respect to a person’s service prior to the date of such termination. Any repeal or modification of this Article XII or any repeal or modification of the Illinois Business Corporation Act or any other applicable law shall not limit any rights under this Article XII then existing or arising out of events, acts, omissions or circumstances occurring or existing prior to such repeal or modification, including, without limitation, the right to indemnification and advancement of expenses for proceedings commenced after such repeal or modification to enforce this Article XII with regard to acts, omissions, events or circumstances occurring or existing prior to such repeal or modification. If the scope of indemnity provided by this Article XII or any replacement article, or pursuant to the Illinois Business Corporation Act or any modification or replacement thereof is increased, then such person shall be entitled to such increased indemnification as is in existence at the time indemnity is provided to such person, it being the intent, subject to Section 10 of this Article XII, to indemnify persons specified in this Article XII to the fullest extent permitted by law.

SECTION 6. The 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 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 him and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability under the provisions of this Article.

SECTION 7. Subject to Section 10 of this Article XII, if a claim under this Article XII is not promptly paid in full by the corporation after a written claim has been received by the corporation or if expenses pursuant to Section 4 of this Article XII have not been promptly advanced after a written request for such advancement accompanied by the statement and undertaking required by Section 4 of this Article XII has been received by the corporation, the director or officer may at any time thereafter bring suit against the corporation to recover the unpaid amount of the claim or the advancement of expenses. If successful, in whole or in part, in such suit, such director or officer shall

also be entitled to be paid the reasonable expense thereof, including attorneys’ fees. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking has been tendered to the corporation) that the director or officer has not met the standards of conduct which make it permissible under the Illinois Business Corporation Act for the corporation to indemnify the director or officer for the amount claimed, but the burden of proving such defense shall be on the corporation. Neither the failure of the corporation (including its board of directors, independent legal counsel, or its shareholders) to have made a determination, if required, prior to the commencement of such action that indemnification of the director or officer is proper in the circumstances because he or she has met the applicable standard of conduct required under the Illinois Business Corporation Act, nor an actual determination by the corporation (including its board of directors, independent legal counsel, or its shareholders) that the director or officer had not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the director or officer had not met the applicable standard of conduct.

SECTION 8. For purposes of this Article XII, 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 or officer of such merging corporation, or was serving at the request of such merging corporation as a director or officer of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under the provisions of this Article XII with respect to the surviving corporation as such person would have with respect to such merging corporation if its separate existence had continued.

SECTION 9. For purposes of this Article XII, references 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; references to “serving at the request of the corporation” shall include any service as a director, officer or 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; and references to “officers” shall include elected officers and appointed officers. A person who acted in good faith and in a manner he reasonably believed to be in the best interest 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 Article XII.

SECTION 10. Anything herein to the contrary notwithstanding, if the corporation purchases insurance in accordance with Section 6 of this Article XII, the corporation shall not be required to, but may (if the board of directors so determines in accordance with this Article XII) reimburse any party instituting any action, suit or proceeding if a result of the institution thereof is the denial of or limitation of payment of losses under

such insurance when such losses would have been paid thereunder if a non-insured third party had instituted such action, suit or proceedings.

ARTICLE XIII

INDEMNIFICATION OF EMPLOYEES AND AGENTS

The corporation may indemnify any agent or employee of the corporation who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding (including, but not limited to any such proceeding by or in the right of the corporation) whether civil, criminal, administrative or investigative, by reason of the fact that he is or was serving the corporation at its request and in the course and scope of his duties and acting in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation, against expenses (including reasonable attorney’s fees) actually and reasonably incurred by him in connection with the defense or settlement of such action, suit or proceeding. The standards of conduct, the provisions for payment and advances, and the terms and conditions contained in Article XII, Sections 1, 2, 3, 4, 5(a), 6, 8, 9 and 10 shall apply to any indemnification hereunder.
