Each Stockholder Meeting Notice must be delivered personally to, or be mailed to and received by, the Secretary of the corporation at the principal executive offices of the corporation in the City of Chicago, State of Illinois, not less than 60 days nor more than 90 days prior to the annual meeting; provided, however, that in the event that less than 75 days’ notice or prior public disclosure of the date of the annual meeting is given or made to stockholders, notice by the stockholder to be timely must be received not later than the close of business on the tenth day following the day on which such notice of the date of the annual meeting was mailed or such public disclosure was made, whichever first occurs. Each Stockholder Meeting Notice shall set forth: (i) a description of each item of business proposed to be brought before the meeting and the reasons for conducting such business at the annual meeting; (ii) any material interest in such business of such stockholder and any Stockholder

The person presiding at the annual meeting of stockholders shall, if the facts so warrant, determine that business was not properly brought before the meeting in accordance with the provisions of this Section and, if such person should so determine, such person should so declare to the meeting and any such business so determined to be not properly brought before the meeting shall not be transacted.

“Stockholder Associated Person” shall mean, with respect to any stockholder, any person directly or indirectly controlling, controlled by, under common control with or acting in concert with such stockholder.

Section 2.2. Special Meetings. Special meetings of the stockholders, for any purpose or purposes, unless otherwise prescribed by statute or by the certificate of incorporation, may be called by the Chief Executive Officer, the President, or the Chairman and shall be called by the Secretary pursuant to . (i) a written request to the Secretary, submitted by one or more stockholders (each such request, a “Special Meeting Request”) owning as of the date of such Special Meeting Request, in the aggregate, at least 10% of the combined voting power of the then outstanding shares of all classes and series of capital stock of the corporation entitled to vote on the matter or matters to be brought before the proposed special meeting, voting as a single class or (ii) a resolution duly adopted by the affirmative vote of a majority of the Whole Board of Directors. In determining whether Special Meeting Requests have met the requirements of this

Section 2.2, (i) multiple Special Meeting Requests will not be considered together if they relate to different items of business and (ii) all Special Meeting Requests relating to an item of business must have been dated and delivered to the Secretary within 60 days of the earliest dated Special Meeting Request relating to such item of business. Any notice relating to a special meeting appropriately called pursuant to this Section 2.2 shall describe the item or items of business to be considered at such special meeting. Business transacted at any special meeting shall be limited to the matters identified in the corporation’s notice relating to such special meeting ; provided, however, that nothing herein shall prohibit the Board from submitting additional matters to the stockholders at any special meeting requested by the stockholders.

A Special Meeting Request shall be signed by each stockholder, or duly authorized agent of each such stockholder, requesting the special meeting and shall set forth: (i) a brief description of each item of business desired to be brought before the special meeting and the reasons for conducting such business at the special meeting, (ii) any material interest of each stockholder requesting the special meeting in the business desired to be brought before the special meeting, (iii) the name and address of each stockholder requesting the special meeting, (iv) the class and number of shares of stock of the corporation which are owned, beneficially or of record, by each stockholder requesting the special meeting as of the date of the Special Meeting Request, (v) an agreement by each stockholder requesting the special meeting to notify the corporation immediately in the case of any disposition prior to the record date for the proposed special meeting of shares of stock of the corporation owned, beneficially or of record, and an acknowledgement that any such disposition shall be deemed a revocation of such Special Meeting Request with respect to such shares and (vi) any other information that would be required to be set forth with respect to an Annual Meeting in a Stockholder Meeting Notice, or updated, pursuant to Section 2.1 of these By-laws and, if the purpose of the special meeting includes the election of one or more directors, Section 3.12.

A stockholder may revoke a Special Meeting Request at any time prior to the special meeting by written revocation delivered to the Secretary at the principal executive offices of the corporation; provided however, that if any such revocations are received by the Secretary and, as a result of such revocation, the number of un-revoked Special Meeting Requests no longer represents at least the requisite number of shares entitling the stockholders to request the calling of a special meeting pursuant to this Section 2.2, then the Board of Directors shall have the discretion to determine whether or not to proceed with the special meeting. If none of the stockholders who submitted a Special Meeting Request appears or sends a qualified representative to present the item of business submitted by the stockholders for consideration at the special meeting, such item of business shall not be submitted for vote of the stockholders at such special meeting, notwithstanding that proxies in respect of such vote may have been received by the corporation or such stockholder(s). A Special Meeting Request shall not be valid (and the Board of Directors shall have no obligation to call a special meeting in respect of such Special Meeting Request) if it relates to an item of business that is not a proper subject for stockholder action under applicable law, would violate the law, or would cause the company to violate the law.

The procedures set forth in this Section 2.2 are the exclusive means by which items of business may be raised by stockholders at a special meeting of stockholders.

Notwithstanding the foregoing, a special meeting called by stockholders need not be held if either (i) the Board of Directors has called or calls for an annual meeting of stockholders to be held within 90 days after the date of receipt of one or more Special Meeting Requests representing the requisite number of shares for the calling of a special meeting (the “Meeting Request Date”) and the Board determines in good faith that the business of such annual meeting includes (among any other matters properly brought forth before the annual meeting) the business specified in the Special Meeting Request or Requests or (ii) the item that is the subject of such Special Meeting Request or Requests was voted on at any meeting of stockholders held within 30 days prior to the Meeting Request Date (it being understood that, for purposes of this Section 2.2, the election or removal of directors shall be deemed the same item with respect to all items involving the election or removal of directors).

Section 2.3. Place of Special Meetings. Any special meeting of the stockholders properly called in accordance with Section 2.2 of these By-laws shall be held at such date, time and place, within or without the State of Delaware, as may be fixed by resolution of the Board of Directors from time to time ; provided that, with respect to special meetings called by a stockholder or group of stockholders, the date of any such special meeting shall not be more than 90 days after the Meeting Request Date.

Section 2.4. Notice of Meetings. A written notice of each annual or special meeting of stockholders shall be given stating the date, time and place of the meeting and, in case of a special meeting, the purpose or purposes for which the meeting is called.

If no record date is fixed, (i) the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next

preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held; and (ii) the record date for determining stockholders for any other purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting, but the Board of Directors may fix a new record date for the adjourned meeting.

Section 2.6. Voting List. The Secretary shall prepare, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten days prior to the meeting during ordinary business hours, at the principal place of business of the corporation. The list shall also be produced and kept at the time and place of the meeting during the whole time thereof and may be inspected by any stockholder who is present.

Section 2.7. Quorum. The holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders for the transaction of business except as otherwise provided by statute or by the certificate of incorporation.

At such adjourned meeting at which a quorum shall be present or represented any business may be transacted which might have been transacted at the meeting as originally notified.

Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy filed with the Secretary before or at the time of the meeting. No such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period.

Section 2.9. Voting. When a quorum is present at any meeting of stockholders, the affirmative vote of the holders of a majority of the stock present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall decide any question brought before such meeting, unless the question is one upon which, by express provision of the statutes, the certificate of incorporation or these By-laws, a different vote is required, in which case such express provision shall govern and control the decision of such question. Every stockholder having the right to vote shall be entitled to vote in person or by proxy. Every such stockholder shall have one vote for each share of stock having voting power registered in such stockholder’s name on the books of the corporation.

Section 2.10. Voting of Stock of Certain Holders. Shares of stock of the corporation standing in the name of another corporation, domestic or foreign, and entitled to vote may be

voted by such officer, agent or proxy as the by-laws or other internal regulations of such corporation may prescribe or, in the absence of such provision, as the board of directors or comparable body of such corporation may determine.

Except as otherwise provided pursuant to the certificate of incorporation relating to the rights of the holders of any one or more classes or series of Preferred Stock issued by the corporation, acting separately by class or series, each director shall be elected by the vote of the majority of the votes cast (meaning the number of shares voted “for” a nominee must exceed the number of shares voted “against” such nominee) at any meeting for the election of directors at which a quorum is present, provided that the directors shall be elected by a plurality of the votes cast (instead of by votes cast for or against a nominee) at any meeting at which a quorum is present for which (i) the Secretary of the Corporation receives a notice in compliance with the applicable requirements for stockholder nominations for director set forth in these By-laws that a stockholder proposes to nominate a person for election to the Board of Directors and (ii) such proposed nomination has not been withdrawn by such stockholder on or prior to the tenth day preceding the date the corporation first mails its notice of meeting for such meeting to the stockholders.

Section 4.14. Treasurer. The Treasurer shall be responsible for the receipt, custody and disbursement of all funds of the corporation in the form of both cash and securities.

Section 4.15. Controller. The Controller reports to the Chief Executive Officer directly or through such other management executives as the Chief Executive Officer may direct.

The Chief Executive Officer may appoint any individual an officer having such title as the Chief Executive Officer shall deem appropriate, provided such officer is not an officer subject to Section 16 of the Exchange Act. Any such officer appointed by the Chief Executive Officer may be removed by the Chief Executive Officer whenever in the Chief Executive Officer’s judgment the best interests of the corporation would be served thereby. The term of office, compensation, powers and duties and other terms of employment of appointed officers shall be such as the Chief Executive Officer may from time to time deem proper, and the authority of such officers shall be limited to acts pertaining to the business of the unit, operation or function to which they are assigned.

Checks, etc. All checks, demands, drafts or other orders for the payment of money, notes or other evidences of indebtedness issued in the name of the corporation shall be signed by such officer or officers or such agent or agents of the corporation, and in such manner, as may be designated by the Board of Directors or by one or more officers of the corporation named by the Board of Directors for such purpose.

Section 6.4. Deposits.

Section 7.1. Certificates of Stock. Shares of the corporation’s stock may be certificated or uncertificated. Any certificates of stock of the corporation shall be in such form as may be determined by the Board of Directors, shall be numbered and shall be entered in the books of the corporation as they are issued. Any such certificates shall exhibit the holder’s name and number

of shares and shall be signed by the Chief Executive Officer, or President or a Vice President and by the Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer. If any stock certificate is signed manually (a) by a transfer agent other than the corporation or its employee or (b) by a registrar other than the corporation or its employee, any other signature on the certificate may be a facsimile.

In case any officer, transfer agent or registrar who has signed or whose facsimile has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, such certificate may nevertheless be issued by the corporation with the same effect as if such officer, transfer agent or registrar continued to be such at the date of issue. All certificates properly surrendered to the corporation for transfer shall be cancelled and no new certificates shall be issued to evidence transferred shares until the former certificate for at least a like number of shares shall have been surrendered and cancelled and the corporation reimbursed for any applicable taxes on the transfer, except that in the case of a lost, destroyed or mutilated certificate, a new one may be issued therefor upon such terms, and with such indemnification (if any) to the corporation, as the Board of Directors may prescribe specifically or in general terms or by delegation to a transfer agent for the corporation. Certificates shall not be issued representing fractional shares of stock.

Section 7.2. Lost Certificates. The Board of Directors may direct a new certificate or certificates to be issued in place of any certificate or certificates theretofore issued by the corporation alleged to have been lost or destroyed upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost or destroyed. When authorizing such issue of a new certificate or certificates, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost or destroyed certificates, or such owner’s legal representative, to advertise the same in such manner as it shall require and/or to give the corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate alleged to have been lost or destroyed.

Section 7.3. Transfers. Upon surrender to the corporation or the transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. Uncertificated shares shall be transferred upon the receipt of proper transfer instructions from the registered owner of such uncertificated shares. Transfers of shares shall be made only on the books of the corporation by the registered holder thereof or by such holder’s attorney thereunto authorized by power of attorney and filed with the Secretary or transfer agent of the corporation.

Section 8.1. Declaration. Dividends upon the capital stock of the corporation, subject to the provisions of the certificate of incorporation, if any, may be declared by the Board of Directors at any regular or special meeting, pursuant to law.

Section 8.2. Reserve. Before payment of any dividend, there may be set aside out of any funds of the corporation available for dividends such sum or sums as the Directors from time to time, in their absolute discretion, think proper as a reserve or reserves to meet contingencies, or for equalizing dividends, or for repairing or maintaining any property of the corporation, or such other purposes as the Directors shall think conducive to the interest of the corporation, and the Directors may modify or abolish any such reserve in the manner in which it was created.

Section 9.1. Fiscal Year. Unless otherwise fixed by the resolution of the Board of Directors, the fiscal year of the corporation shall be the calendar year.

Section 9.4. Forum for Certain Actions. Unless the Board of Directors, acting on behalf of the corporation, consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another state court located with the State of Delaware or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any Director, officer or other employee of the corporation to the corporation or the stockholders, (iii) any action asserting a claim against the corporation or any of its Directors, officers or other employees arising pursuant to any provision of the Delaware General Corporation Law, the certificate of incorporation or these By-laws (in each case, as may be amended from time to time) or (iv) any action asserting a claim against the corporation or any of its Directors, officers or other employees governed by the internal affairs doctrine of the State of Delaware, in all cases subject to the court having personal jurisdiction over all indispensible parties named as

defendants. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the corporation shall be deemed to have notice of and consented to the provisions of this Section 9.4.

These By-laws may be altered, amended or repealed at any regular meeting of the Board of Directors or at any special meeting of the Board of Directors if notice of such alteration, amendment or repeal be contained in the notice of such special meeting, provided that no amendment of these By-laws shall conflict with the provisions of the Certificate of Incorporation, whether relating to the number of Directors which shall constitute the Whole Board or otherwise.
