STOCKHOLDERS’ MEETINGS

SECTION 1. TIME. The annual meeting of the stockholders of the corporation for the election of directors and the transaction of such other business as may properly come before such meeting shall be held each year on the second Wednesday in October at 9:00 a.m. (Chicago time), or if said day be a legal holiday, then on the next succeeding day not a legal holiday, or shall be held on such other date and at such other time as shall be determined by the Board of Directors. A special meeting of the stockholders shall be held on the date and at the time fixed by those persons authorized by the Certificate of Incorporation to call such meeting.

SECTION 2. PLACE. Annual meetings and special meetings shall be held at such place, within or without the State of Delaware, as may be designated from time to time by the Board of Directors. If authorized by the Board of Directors, a meeting may be held solely by means of remote communications as authorized by the General Corporation Law. Whenever the directors shall fail to designate a place for a meeting or authorize holding the meeting solely by means of remote communications, the meeting shall be held at the principal office of the corporation.

SECTION 3. NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall be given, stating the place, if any, date and hour of the meeting, the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called. Except as otherwise provided by the General Corporation Law, notice of any meeting shall be given, personally or by mail or electronic transmission, not less

than ten days nor more than sixty days before the date of the meeting to each stockholder entitled to vote at such meeting. If mailed, notice is given when deposited in the United States mail, postage prepaid, directed to each stockholder at such stockholder’s address as it appears on the records of the corporation. If a meeting is adjourned to another time or place, except as provided below notice need not be given of the adjourned meeting if the time, place, if any, thereof and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken. At the adjourned meeting, any business may be transacted which might have been transacted at the meeting as originally noticed. If the adjournment is for more than 30 days, or if after the announcement a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder or record entitled to vote at the meeting. A written waiver, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice or any waiver by electronic transmission.

SECTION 4. RECORD DATE FOR STOCKHOLDERS.

(a) In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than sixty days nor less than ten days before the date of such meeting. If no record date is fixed by the Board of Directors, 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. 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; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

(b) In order that the corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or the allotment of any rights, or the stockholders entitled to exercise any rights in respect of any change, conversion, or exchange of stock, or for the purpose of any other lawful action, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than sixty days prior to any such action. If no record date is fixed by the Board of Directors, the record date for determining stockholders for any other purpose shall be the close of business on the day on which the Board of Directors adopts the resolution relating thereto.

SECTION 5. STOCKHOLDER LIST. The officer who has charge of the stock ledger of the corporation shall prepare and make, 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 of each stockholder and the number of shares registered in the name of each stockholder, provided that the corporation shall not be required to include electronic mail addresses or any other electronic contact information on such list. 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, either (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the corporation. If the meeting is to be held at a place, then the list shall 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. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. The stock ledger shall be the only evidence as to who are the stockholders entitled to examine the stock ledger, the list required by this section or the books of the corporation, or to vote in person or by proxy at any meeting of stockholders.

SECTION 6. CONDUCT OF MEETING. Meetings of the stockholders shall be presided over by one of the following officers in the order presented and if present and acting: the Chairman of the Board, a Vice Chairman, if any, the President, an Executive Vice President, a Vice President, or the Chairman of the Nominating and Governance Committee, or, if none of the designated persons is in office and present and acting, by a chairman to be chosen by the stockholders. The person presiding over the meeting shall have authority to prescribe the agenda for the meeting and to control the length and order of discussion. The Secretary of the corporation, or in the Secretary’s absence, an Assistant Secretary, shall act as Secretary of every meeting, but if neither the Secretary nor an Assistant Secretary is present, the chairman of the meeting shall appoint a secretary of the meeting.

SECTION 7. PROXY REPRESENTATION. Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date unless the proxy provides for a longer period. Without limiting the manner in which a stockholder may authorize another person or person to act for such stockholder as proxy pursuant to this section, a stockholder may grant such authority by (a) executing a writing authorizing another person or persons to act for such stockholder as proxy or (b) transmitting or authorizing the transmission of a telegram, cablegram or other means of electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization or like agent duly authorized by the person who will be the holder of the proxy to receive such transmission, provided that any such telegram, cablegram or other means of electronic transmission must either set forth or be submitted with information from which it can be determined that the telegram, cablegram or other electronic transmission was authorized by the stockholder or stockholders’ attorney-in-fact, or (c) any other means permitted under the General Corporation Law. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the corporation generally.

SECTION 8. INSPECTORS OF ELECTIONS. The corporation shall, in advance of any meeting of stockholders, appoint one or more inspectors to act at the meeting and make a written report thereof. The corporation may designate one of more person as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector’s ability. The inspectors shall ascertain the number of shares outstanding and the voting power of each; determine the shares represented at the meeting and the validity of proxies and ballots; count all votes and ballots; determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors; and certify their determination of the number of shares represented at the meeting, and their count of all votes and ballots.

SECTION 9. QUORUM. The holders of a majority of the outstanding shares of stock present or represented by proxy at any meeting of stockholders shall constitute a quorum at such meeting for the transaction of any business. Once a quorum is established at a meeting, it shall remain duly constituted for such meeting notwithstanding the subsequent withdrawal of stockholders. If a quorum shall not be present or represented at any meeting of stockholders, the presiding officer at the meeting or the stockholders present or represented by proxy at the meeting shall have power to adjourn the meeting from time to time until a quorum shall be present or represented.

SECTION 10. VOTING. Each stockholder shall be entitled to one vote for each share of stock held by such stockholder. In all matters other than the election of directors, if a quorum is present, the affirmative vote of the majority of shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the stockholders, unless a different number of votes is required by the Certificate of Incorporation or the General Corporation Law. If a quorum is present, directors shall be elected by a plurality of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. In determining whether a proposal has been approved, shares abstaining or not voting but otherwise present at the meeting will not be counted as having been voted on the proposal. All elections of directors shall be by written ballot. Voting by ballot shall not be required for any other corporate action except as otherwise provided by the General Corporation Law.

Members of the Board of Directors or any committee designated by the Board of Directors may participate in a meeting of the Board of Directors or such committee by means of conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other, and participation in a meeting pursuant to this sentence shall constitute presence in person at the meeting.

SECTION 6. MANNER OF ACTING. The vote of the majority of the directors present at a meeting at which a quorum is present shall be the act of the Board of Directors or committee, as the case may be, unless the Certificate of Incorporation or these by-laws shall require a vote of a greater number.

Any stockholder, upon written request to the transfer agent or registrar of the corporation, shall be entitled to a certificate representing shares of the corporation’s stock. Any certificates representing shares of the corporation’s stock shall be in such form not inconsistent with the Certificate of Incorporation as the Board of Directors may from time to time prescribe. Such certificates shall be signed by or in the name of the corporation by the Chairman or Vice Chairman of the Board of Directors, or the President or a Vice President, and by the Secretary or an Assistant Secretary or the Treasurer or an Assistant Treasurer, and shall be sealed with the seal of the corporation. Such seal may be a facsimile. If a stock certificate is countersigned by a transfer agent or registrar (other than, in each case, the corporation or an employee of the corporation), any or all of the other signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon such certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he or she were such officer, transfer agent or registrar at the date of issue. The name of the person to whom the shares represented by a certificate are issued, and the number of shares and date of issue, shall be entered on the books of the corporation.

SECTION 2. TRANSFER. Upon compliance with any provisions restricting the transferability of shares that may be set forth in the Certificate of Incorporation, these by-laws or any written agreement in respect thereof, transfers of shares of the capital stock of the corporation shall be made only on the books of the corporation by the holder of record thereof or by such holder’s legal representative, who shall furnish proper evidence of authority to transfer, or by the holder’s attorney thereunto authorized by power of attorney duly executed and filed with the Secretary of the corporation, or with a transfer agent appointed as provided in Section 5

of this Article, and either (a) in the case of stock represented by a certificate, on surrender for cancellation of the certificate or certificates for such shares or (b) in the case of uncertificated shares, on proper instructions from the holder of record of such shares or the holder’s legal representative or attorney. and the payment of all taxes thereon. The person in whose name shares of stock stand on the books of the corporation shall be deemed the owner thereof for all purposes as regards the corporation. The Board may, from time to time, make such additional rules and regulations as it may deem expedient, not inconsistent with these by-laws, concerning the issue, transfer and registration of certificates for shares of the capital stock of the corporation.

SECTION 3. LOST, STOLEN, DESTROYED OR MUTILATED CERTIFICATES. No certificates for shares of stock in the corporation shall be issued in place of any certificate alleged to have been lost, destroyed or stolen, except on production of such evidence of such loss, destruction or theft and on delivery to the corporation, if the Board of Directors shall so require, of a bond of indemnity in such amount (not exceeding twice the value of the shares represented by such certificate), upon such terms and secured by such surety as the Board of Directors may in its discretion require.

SECTION 4. TRANSFER AGENT AND REGISTRAR. The Board of Directors may appoint one or more transfer agents and one or more registrars, and may require all certificates of stock to bear the signature or signatures of any of them.
