The authority of the board of directors with respect to each series of Preferred Stock shall include (without limitation) the determination of the following:

(a) the dividend rate on the shares of such series, whether dividends shall be cumulative, and, if so, from which date or dates, and the rights of priority, if any, with respect to the payment of dividends on the shares of such series relative to other series of Preferred Stock or classes of stock;

Pursuant to the above stated authority, the board of directors has designated the following series of Preferred Stock:

SECTION 2. DESIGNATION AND AMOUNT.

The shares of such series shall be designated as “Series A Junior Participating Preferred Stock” and the number of shares constituting such series shall be 140,000.

SECTION 3. DIVIDENDS AND DISTRIBUTIONS.

(a) The holders of shares of Series A Junior Participating Preferred Stock shall be entitled to receive, when, as and if declared by the board of directors out of funds legally available for the purpose, quarterly dividends payable in cash on the last day of March, June, September and December in each year (each such date being referred to herein as a “Quarterly Dividend Payment Date”), commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Series A Junior Participating Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (x) $.01 or (y) subject to the provision for adjustment hereinafter set forth, 1,000 times the aggregate per share amount of all cash dividends, and 1,000 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Class A Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Class A Common Stock, since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Series A Junior Participating Preferred Stock. In the event the corporation shall at any time after the date of consummation of the merger of CME Merger Subsidiary Inc. with and into the Exchange (as defined below) (the “Rights Declaration Date”) (i) declare any dividend on Class A Common Stock payable in shares of Class A Common Stock, (ii) subdivide the outstanding Class A Common Stock, or (iii) combine the outstanding Class A Common Stock into a smaller number of shares, then in each such case the amount to which holders of shares of Series A Junior Participating Preferred Stock were entitled immediately prior to such event under clause (y) of the preceding sentence shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Class A Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Class A Common Stock that were outstanding immediately prior to such event.

(b) The corporation shall declare a dividend or distribution on the Series A Junior Participating Preferred Stock as provided in Paragraph (a) above immediately after it declares a dividend or distribution on the Class A Common Stock (other than a dividend payable in shares of Class A Common Stock); provided that, in the event no dividend or distribution shall have been declared on the Class A Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $.01 per share on the Series A Junior Participating Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date.

(c) Dividends shall begin to accrue and be cumulative on outstanding shares of Series A Junior Participating Preferred Stock from the Quarterly Dividend Payment Date next preceding the date of issue of such shares of Series A Junior Participating Preferred Stock, unless the date of issue of such shares is prior to the record date for the first Quarterly Dividend Payment Date, in which case dividends on such shares shall begin to accrue from the date of issue of such shares, or unless the date of issue is a Quarterly Dividend Payment Date or is a date after the record date for the determination of holders of shares of Series A Junior Participating Preferred Stock entitled to receive a quarterly dividend and before such Quarterly Dividend Payment Date, in either of which events such dividends shall begin to accrue and be cumulative from such Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear interest. Dividends paid on the shares of Series A Junior Participating Preferred Stock in an amount less than the total amount of such dividends at the time accrued and payable on such shares shall be allocated pro rata on a share-by-share basis among all such shares at the time outstanding. The board of directors may fix a record date for the determination of holders of shares of Series A Junior Participating Preferred Stock entitled to receive payment of a dividend or distribution declared thereon, which record date shall be no more than 30 days prior to the date fixed for the payment thereof.

SECTION 4. VOTING RIGHTS.

The holders of shares of Series A Junior Participating Preferred Stock shall have the following voting rights:

(a) Subject to the provision for adjustment hereinafter set forth, each share of Series A Junior Participating Preferred Stock shall entitle the holder thereof to 1,000 votes on all matters submitted to a vote of the shareholders of the corporation. In the event the corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Class A Common Stock payable in shares of Class A Common Stock, (ii) subdivide the outstanding Class A Common Stock, or (iii) combine the outstanding Class A Common Stock into a smaller number of shares, then in each such case the number of votes per share to which holders of shares of Series A Junior Participating Preferred Stock were entitled immediately prior to such event shall be adjusted by multiplying such number by a fraction the numerator of which is the number of shares of Class A Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Class A Common Stock that were outstanding immediately prior to such event.

(b) Except as otherwise provided herein or by law, the holders of shares of Series A Junior Participating Preferred Stock and the holders of shares of Class A Common Stock and Class B Common Stock shall vote together as one class on all matters submitted to a vote of shareholders of the corporation.

(c) (i)  If at any time dividends on any Series A Junior Participating Preferred Stock shall be in arrears in an amount equal to six quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a “default period”) which shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all  shares of Series A Junior Participating Preferred Stock then outstanding shall have been declared and paid or set apart for payment. During each default period, all holders of Preferred Stock (including holders of the Series A Junior Participating Preferred Stock) with dividends in arrears in an amount equal to six quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect two directors.

(ii) During any default period, such voting right of the holders of Series A Junior Participating Preferred Stock may be exercised initially at a special meeting called pursuant to Paragraph (c)(iii) of this Section 3 or at any annual meeting of shareholders, and thereafter at annual meetings of shareholders, provided that such voting right shall not be exercised unless the holders of 10% in number of shares of Preferred Stock outstanding shall be present in person or by proxy. The absence of a quorum of the holders of Common Stock shall not affect the exercise by the holders of Preferred Stock of such voting right. At any meeting at which the holders of Preferred Stock shall exercise such voting right initially during an existing default period, they shall have the right, voting as a class, to elect directors to fill such vacancies, if any, in the board of directors as may then exist up to two directors or, if such right is exercised at an annual meeting, to elect two directors. If the number which may be so elected at any special meeting does not amount to the required number, the holders of the Preferred Stock shall have the right to make such increase in the number of directors as shall be necessary to permit the election by them of the required number. After the holders of the Preferred Stock shall have exercised their right to elect directors in any default period and during the continuance of such period, the number of directors shall not be increased or decreased except by vote of the holders of Preferred Stock as herein provided or pursuant to the rights of any equity securities ranking senior to or pari passu with the Series A Junior Participating Preferred Stock.

(iii) Unless the holders of Preferred Stock shall, during an existing default period, have previously exercised their right to elect directors, the board of directors may order, or any shareholder or shareholders owning in the aggregate not less than 10% of the total number of shares of Preferred Stock outstanding, irrespective of series, may request, the calling of a special meeting of the holders of Preferred Stock, which meeting shall thereupon be called by the Chairman of the Board, the President, any Managing Director or the Secretary of the corporation. Notice of such meeting and of any annual meeting at which holders of Preferred Stock are entitled to vote pursuant to this Paragraph (c)(iii) shall be given to each holder of record of Preferred Stock by mailing a copy of such notice to him or her at his or her last address as the same appears on the books of the corporation. Such meeting shall be called for a time not earlier than 20 days and not later than 60 days after such order or request or in default of the calling of such meeting within 60 days after such order or request, such meeting may be called on similar notice by any shareholder or shareholders owning in the aggregate not less than 10% of the total number of shares of Preferred Stock outstanding. Notwithstanding the provisions of this Paragraph (c)(iii), no such special meeting shall be called during the period within 60 days immediately preceding the date fixed for the next annual meeting of the shareholders.

(iv) In any default period, the holders of Common Stock, and other classes of stock of the corporation if applicable, shall continue to be entitled to elect the whole number of directors until the holders of Preferred Stock shall have exercised their right to elect two directors voting as a class, after the exercise of which right (x) the directors so elected by the holders of Preferred Stock shall continue in office until their successors shall have been elected by such holders or until the expiration of the default period, and (y) any vacancy in the board of directors may (except as provided in Paragraph (c)(ii) of this Section 3) be filled by vote of a majority of the remaining directors theretofore elected by the holders of the class of stock which elected the director whose office shall have become vacant. References in this Paragraph (c) to directors elected by the holders of a particular class of stock shall include directors elected by such directors to fill vacancies as provided in clause (y) of the foregoing sentence.

(v) Immediately upon the expiration of a default period, (x) the right of the holders of Preferred Stock as a class to elect directors shall cease, (y) the term of any directors elected by the holders of Preferred Stock as a class shall terminate, and (z) the number of directors shall be such number as may be provided for in the certificate of incorporation or bylaws irrespective of any increase made pursuant to the provisions of Paragraph (c)(ii) of this Section 3 (such number being subject, however, to change thereafter in any manner provided by law or in the certificate of incorporation or bylaws). Any vacancies in the board of directors effected by the provisions of clauses (y) and (z) in the preceding sentence may be filled by a majority of the remaining directors.

(d) Except as set forth herein, holders of Series A Junior Participating Preferred Stock shall have no special voting rights and their consent shall not be required (except to the extent they are entitled to vote with holders of Common Stock as set forth herein) for taking any corporate action.

SECTION 5. CERTAIN RESTRICTIONS.

(a) Whenever quarterly dividends or other dividends or distributions payable on the Series A Junior Participating Preferred Stock as provided in Section 2 are in arrears, thereafter and until all accrued and unpaid dividends and distributions, whether or not declared, on shares of Series A Junior Participating Preferred Stock outstanding shall have been paid in full, the corporation shall not:

(i) declare or pay dividends on, make any other distributions on, or redeem or purchase or otherwise acquire for consideration any shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock;

(ii) declare or pay dividends on or make any other distributions on any shares of stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Participating Preferred Stock, except dividends paid ratably on the Series A Junior Participating Preferred Stock and all such parity stock on which dividends are payable or in arrears in proportion to the total amounts to which the holders of all such shares are then entitled;

(iii) redeem or purchase or otherwise acquire for consideration shares of any stock ranking on a parity (either as to dividends or upon liquidation, dissolution or winding up) with the Series A Junior Participating Preferred Stock, provided that the corporation may at any time redeem, purchase or otherwise acquire shares of any such parity stock in exchange for shares of any stock of the corporation ranking junior (either as to dividends or upon dissolution, liquidation or winding up) to the Series A Junior Participating Preferred Stock; or

(iv) purchase or otherwise acquire for consideration any shares of Series A Junior Participating Preferred Stock, or any shares of stock ranking on a parity with the Series A Junior Participating Preferred Stock, except in accordance with a purchase offer made in writing or by publication (as determined by the board of directors) to all holders of such  shares upon such terms as the board of directors, after consideration of the respective annual dividend rates and other relative rights and preferences of the respective series and classes, shall determine in good faith will result in fair and equitable treatment among the respective series or classes.

(b) The corporation shall not permit any subsidiary of the corporation to purchase or otherwise acquire for consideration any shares of stock of the corporation unless the corporation could, under Paragraph (a) of this Section 4, purchase or otherwise acquire such shares at such time and in such manner.

SECTION 6. REACQUIRED SHARES.

Any shares of Series A Junior Participating Preferred Stock purchased or otherwise acquired by the corporation in any manner whatsoever shall be retired and cancelled promptly after the acquisition thereof. All such shares shall upon their cancellation become authorized but unissued shares of Preferred Stock and may be reissued as part of a new series of Preferred Stock to be created by resolution or resolutions of the board of directors, subject to the conditions and restrictions on issuance set forth herein.

SECTION 7. LIQUIDATION, DISSOLUTION OR WINDING UP.

(a) Upon any liquidation (voluntary or otherwise), dissolution or winding up of the corporation, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Series A Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Series A Junior Participating Preferred Stock shall have received an amount equal to 1,000 times the Exercise Price, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the “Series A Liquidation Preference”). Following the payment of the full amount of the Series A Liquidation Preference, no additional distributions shall be made to the holders of shares of Series A Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the “Common Adjustment”) equal to the quotient obtained by dividing (i) the Series A Liquidation Preference by (ii) 1,000 (as appropriately adjusted as set forth in Paragraph (c) of this Section 6 to reflect such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock) (such number in clause (ii), the “Adjustment Number”). Following the payment of the full amount of the Series A Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Series A Junior Participating Preferred Stock and Common Stock, respectively, holders of Series A Junior Participating Preferred Stock and holders of shares of both classes of Common Stock shall receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number to 1 with respect to such Preferred Stock and Common Stock, on a per share basis, respectively.

(b) In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of preferred stock, if any, which rank on a parity with the Series A Junior Participating Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of both classes of Common Stock.

(c) In the event the corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Class A Common Stock payable in shares of Class A Common Stock, (ii) subdivide the outstanding Class A Common Stock, or (iii) combine the outstanding Class A Common Stock into a smaller number of shares, then in each such case the Adjustment Number in effect immediately prior to such event shall be adjusted by multiplying such Adjustment Number by a fraction the numerator of which is the number of shares of Class A Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Class A Common Stock that were outstanding immediately prior to such event.

SECTION 8. CONSOLIDATION, MERGER, ETC.

In case the corporation shall enter into any consolidation, merger, combination or other transaction in which the shares of Class A Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case the shares of Series A Junior Participating Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share (subject to the provision for adjustment hereinafter set forth) equal to 1,000 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Class A Common Stock is changed or exchanged. In the event the corporation shall at any time after the Rights Declaration Date (i) declare any dividend on Class A Common Stock payable in shares of Class A Common Stock, (ii) subdivide the outstanding Class A Common Stock, or (iii) combine the outstanding Class A Common Stock into a smaller number of shares, then in each such case the amount set forth in the preceding sentence with respect to the exchange or change of shares of Series A Junior Participating Preferred Stock shall be adjusted by multiplying such amount by a fraction the numerator of which is the number of shares of Class A Common Stock outstanding immediately after such event and the denominator of which is the number of shares of Class A Common Stock that were outstanding immediately prior to such event.

SECTION 9. NO REDEMPTION.

The shares of Series A Junior Participating Preferred Stock shall not be redeemable.

SECTION 10. AMENDMENT.

The Certificate of Incorporation of the corporation shall not be further amended in any manner which would materially alter or change the powers, preferences or special rights of the Series A Junior Participating Preferred Stock so as to affect them adversely without the affirmative vote of the holders of a majority or more of the outstanding shares of Series A Junior Participating Preferred Stock, voting separately as a class.

SECTION 11. FRACTIONAL SHARES.

Series A Junior Participating Preferred Stock may be issued in fractions of a share which shall entitle the holder, in proportion to such holders fractional shares, to exercise voting rights, receive dividends, participate in distributions and to have the benefit of all other rights of holders of Series A Junior Participating Preferred Stock.

The corporation shall cause the Exchange, (i) as long as an open outcry market is liquid (as defined below), to maintain for such open outcry market a facility for conducting business, for the dissemination of price information, for clearing and delivery and (ii) to provide reasonable financial support (consistent with the calendar year 1999 budget levels established by Chicago Mercantile Exchange, an Illinois not-for-profit corporation, the predecessor of the Exchange) for technology, marketing and research for open outcry markets. If an open outcry market is not liquid, as determined by the board of directors, the board may determine, in its sole discretion, whether such obligations will continue, and for how long, in respect of such market. For purposes of this Section, an open outcry market will be deemed “liquid” if it meets any of the following tests on a quarterly basis:

(a) if a comparable exchange-traded product exists, including electronic trading at the Exchange, the Exchange’s open outcry market has maintained at least 30% of the average daily volume of such comparable product (including, for calculation purposes, volume from exchange-for-physical transactions in such open outcry market); or

(b) if a comparable exchange-traded product exists and the product trades exclusively by open outcry at the Exchange, the Exchange’s open outcry market has maintained at least 30% of the open interest of such comparable product; or

(c) if no comparable exchange-traded product exists, the open outcry market has maintained at least 40% of the average quarterly volume in that market during 1999 at Chicago Mercantile Exchange, an Illinois not-for-profit corporation, the predecessor of the Exchange (including, for calculation purposes, volume from exchange-for-physical transactions in such open outcry market); or

(d) if no comparable exchange-traded product exists and the product trades exclusively by open outcry, the open outcry market has maintained at least 40% of the average open interest in that market during 1999 at Chicago Mercantile Exchange, an Illinois not-for-profit corporation, the predecessor of the Exchange.

ARTICLE FIVE:

(A) As of the time of acceptance by the Delaware Secretary of State of the filing of this Certificate of Incorporation (the “Effective Time”), the board of directors of the corporation shall consist of 30 members, including 24 directors that are not Class B Directors (the “Equity Directors”), three Class B-1 Directors, two Class B-2 Directors and one Class B-3 Director. Until the annual meeting of shareholders to be held in 2012 (the “2012 Annual Meeting”), at least ten Equity Directors shall be CBOT Directors. During the period starting on the Effective Time and ending on the first business day prior to the 2012 Annual Meeting (i) it shall be a qualification for any director to be nominated or elected by the board of directors to replace any CME Director (whose term is expiring or has expired or who shall have been removed or become disqualified or who shall have resigned, retired, died or otherwise shall fail to continue to serve as a director of the corporation) that such replacement director shall have been designated by the CME Nominating Representatives and (ii) it shall be a qualification for any director to be nominated or elected by the board of directors to replace any CBOT Director (whose term is expiring or has expired or who shall have been removed or become disqualified or who shall have resigned, retired, died or otherwise shall fail to continue to serve as a director of the corporation) that such replacement director shall have been designated by the CBOT Nominating Representatives. For purposes of this certificate of incorporation, the terms “CME Director,” “CME Nominating Representatives,” “CBOT Director” and “CBOT Nominating Representatives” shall have the respective meanings set forth in the corporation’s bylaws as in effect at the Effective Time.

(B) The board of directors of the corporation shall be divided into three classes, designated Class I, Class II and Class III. Each class of directors shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire board of directors of the corporation. At the Effective Time, the board of directors shall consist of the members appointed to the various classes as provided in Article X of the bylaws of the corporation. The terms of the initial Class I directors shall expire at the first annual meeting of shareholders to be held after the Effective Time; the terms of the initial Class II directors shall expire at the second annual meeting of shareholders to be held after the Effective Time; and the terms of the initial Class III directors shall expire at the third annual meeting of shareholders to be held after the Effective Time.

(C) At each annual meeting of shareholders, successors to the class of directors whose terms expire at that annual meeting shall be elected for a three-year term.

(D) A director shall hold office until the annual meeting of shareholders for the year in which his or her term expires and until his or her successor shall be elected and shall qualify, subject, however, to prior death, resignation, retirement, disqualification or removal from office.

(E) Subject to the provisions of Article X of the bylaws of the corporation during the Transition Period (as such term is defined in the bylaws in effect as of the Effective Time) and Paragraph (A) of this Article Five, any vacancy on the board of directors of the corporation may be filled by a majority of the board of directors then in office and any director elected to fill such a vacancy shall have the same remaining term as that of his or her predecessor; PROVIDED, HOWEVER, that any vacancy occurring with respect to a Class B-1 Director, a Class B-2 Director or a Class B-3 Director shall be filled from the candidates who lost for such position from the most recent election, with the candidates being selected to fill such vacancy in the order of the aggregate number of votes received in such previous election.

(F) No person shall be eligible for election as a Class B-1 Director, a Class B-2 Director or a Class B-3 Director unless he or she shall own, or be recognized as the owner for the purposes of the Exchange of, at least one share of the class of Class B Common Stock entitled to elect such director.

(G) Any director may be removed from office at any time, but only for cause and only by the affirmative vote of the holders of at least two-thirds of the voting power of the shares entitled to elect such person as a director.

(H) During the period starting on the Effective Time and ending on the first business day prior to the 2012 Annual Meeting, the corporation shall not amend, modify or repeal, by merger or otherwise, any provision contained in this Article Five or Article Fifteen unless such amendment, modification or repeal is approved by (i) a majority of the CME Directors, and (ii) a majority of the CBOT Directors.

ARTICLE SIX: The board of directors is hereby authorized to create and issue, whether or not in connection with the issuance and sale of any of its stock or other securities or property, rights entitling the holders thereof to purchase from the corporation shares of Preferred Stock, Class A Common Stock or securities of any other corporation. The times at which and the terms upon which such rights are to be issued will be determined by the board of directors and set forth in the contracts or instruments that evidence such rights. The authority of the board of directors with respect to such rights shall include, without limitation, determination of the following:

(A) The initial purchase price per share or other unit of the stock or other securities or property to be purchased upon exercise of such rights;

(B) Provisions relating to the times at which and the circumstances under which such rights may be exercised or sold or otherwise transferred, either together with or separately from, any other stock or other securities of the corporation;

(C) Provisions which adjust the number or exercise price of such rights or amount or nature of the stock or other securities or property receivable upon exercise of such rights in the event of a combination, split or recapitalization of any stock of the corporation, a change in ownership of the corporation’s stock or other securities or a reorganization, merger, consolidation, sale of assets or other occurrence relating to the corporation or any stock of the corporation, and provisions restricting the ability of the corporation to enter into any such transaction absent an assumption by the other party or parties thereto of the obligations of the corporation under such rights;

(D) Provisions which deny the holder of a specified percentage of the outstanding stock or other securities of the corporation the right to exercise such rights and/or cause the rights held by such holder to become void;

ARTICLE NINE: Notwithstanding anything contained in this Certificate of Incorporation to the contrary, the affirmative vote of at least two-thirds of the voting power of the then outstanding Common Stock, voting together as a single class, shall be required to amend, repeal or adopt any provisions inconsistent with Paragraph (G) of Article Five or Articles Six, Nine, Ten, Eleven, Twelve, Thirteen, Fourteen or Fifteen of this Certificate of Incorporation.

ARTICLE TEN: No director of the corporation shall be personally liable to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to the corporation or its shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived an improper personal benefit. Any amendment or repeal of this Article by the shareholders shall not adversely affect any right or protection of a director of the corporation existing hereunder in respect of any act or omission occurring prior to such amendment or repeal.

ARTICLE ELEVEN: The corporation shall indemnify its directors and officers to the fullest extent authorized or permitted by law, as now or hereafter in effect, and such right to indemnification shall continue as to a person who has ceased to be a director or officer of the corporation and shall inure to the benefit of his or her heirs, executors and personal and legal representatives; PROVIDED, HOWEVER, that, except for proceedings to enforce rights to indemnification, the corporation shall not be obligated to indemnify any director or officer (or his or her heirs, executors or personal or legal representatives) in connection with a proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the board of directors. The right to indemnification conferred by this Article Eleven shall include the right to be paid by the corporation the expenses incurred in defending or otherwise participating in any proceeding in advance of its final disposition.

The corporation may, to the extent authorized from time to time by the board of directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the corporation similar to those conferred in this Article Eleven to directors and officers of the corporation.

The rights to indemnification and to the advance of expenses conferred in this Article Eleven shall not be exclusive of any other right which any person may have or hereafter acquire under this Certificate of Incorporation, the bylaws of the corporation, any statute, agreement, vote of shareholders or disinterested directors or otherwise.

Shareholders’ Meetings

Section 1.1 Annual Meetings. (a) The annual meetings of shareholders shall be held on such date, at such time and at such place, either within or without the state of Delaware, as shall be designated from time to time by the Board of Directors and stated in the notice of the meeting. Subject to paragraph (b) of this Section 1.1, any other proper business may be transacted at an annual meeting.

(a) At the annual meetings the shareholders shall elect the Board of Directors, and transact such other business as may properly be brought before the meeting. For such business to be properly brought before the meeting, it must be: (i) authorized by the Board of Directors and specified in the notice, or a supplemental notice, of the meeting, (ii) otherwise brought before the meeting by or at the direction of the Board of Directors or the chairman of the meeting, or (iii) otherwise properly brought before the meeting by a shareholder. For business to be properly brought before an annual meeting by a shareholder, the shareholder must have given written notice thereof to the Secretary, delivered or mailed to and received at the principal executive offices of the Corporation (x) not less than 90 days nor more than 120 days prior to the meeting, or (y) if less than 100 days notice of the meeting or prior public disclosure of the date of the meeting is given or made to shareholders, not later than the close of business on the tenth day following the day on which the notice of the meeting was mailed or, if earlier, the day on which such public disclosure was made. A shareholder’s notice to the Secretary shall set forth as to each item of business the shareholder proposes to bring before the meeting (1) a brief description of such item and the reasons for conducting such business at the meeting and a representation that the shareholder intends to appear in person or by proxy at the meeting to introduce the business specified in the notice, (2) the name and address, as they appear on the Corporation’s records, of the shareholder proposing such business, (3) the class, and series if any, and number of shares of stock of the Corporation which are beneficially owned by the shareholder (for purposes of the regulations under Sections 13 and 14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), and (4) any material interest of the shareholder in such business. No business shall be conducted at any annual meeting except in accordance with the procedures set forth in this paragraph (b). The chairman of the meeting at which any business is proposed by a shareholder shall, if the facts warrant, determine and declare to the meeting that such business was not properly brought before the meeting in accordance with the provisions of this paragraph (b), and, in such event, the business not properly before the meeting shall not be transacted.

Section 1.2 Special Meetings. Special meetings of shareholders for any purpose or purposes may be called at any time only by the Chairman of the Board or by a majority of the total number of authorized Directors. The business transacted at a special meeting of shareholders shall be limited to the purpose or purposes for which such meeting is called.

Section 1.3 Notice of Meetings. A written notice of each annual or special meeting of shareholders shall be given stating the place, date and time of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. Unless otherwise provided by law, the Certificate of Incorporation or these Bylaws, such notice of meeting shall be given not less than 10 nor more than 60 days before the date of the meeting to each shareholder of record entitled to vote at such meeting. If mailed, such notice shall be deemed to be given when deposited in the mail, postage prepaid, directed to the shareholder at such shareholder’s address as it appears on the records of the Corporation. An affidavit of the Secretary or an Assistant Secretary or of the transfer agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

Section 1.4 Adjournments. Any annual or special meeting of shareholders may be adjourned from time to time to reconvene at the same or some other place, and notice need not be given of any such adjourned meeting if the date, time and place thereof 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 original meeting. If the adjournment is for more than 30 days, or if after the adjournment a new record date is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each shareholder of record entitled to vote at the adjourned meeting in accordance with Section 1.3 of these Bylaws.

Section 1.5 Quorum. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the presence in person or by proxy of the holders of stock having not less than one-third of the votes which could be cast by the holders of all outstanding stock entitled to vote at the meeting shall constitute a quorum at each meeting of shareholders. In the absence of a quorum, then either (i) the chairman of the meeting or (ii) the shareholders may, by the affirmative vote of the holders of stock having a majority of the votes which could be cast by all such holders, adjourn the meeting from time to time in the manner provided in Section 1.4 of these Bylaws until a quorum is present. If a quorum is present when a meeting is convened, the subsequent withdrawal of shareholders, even though less than a quorum remains, shall not affect the ability of the remaining shareholders lawfully to transact business.

Section 1.6 Organization. Meetings of shareholders shall be presided over by the Chairman of the Board, the Vice Chairman of the Board or the Chief Executive Officer (in that order), or in their absence, inability or unwillingness, by a chairman designated by the Board of Directors, or in the absence of such designation, by a chairman chosen at the meeting. The Secretary shall act as secretary of the meeting, but in his or her absence, the chairman of the meeting may appoint any person to act as secretary of the meeting. The chairman of any meeting of the shareholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of business.

Section 1.7 Voting. (a) The shareholders entitled to vote at any meeting of shareholders shall be determined in accordance with the provisions of Section 1.10 of these Bylaws, subject to the provisions of Sections 217 and 218 of the Delaware General Corporation Law (relating to voting rights of fiduciaries, pledgors and joint owners of stock and to voting trusts and other voting agreements).

(a) Except as may be otherwise provided in the Certificate of Incorporation or in these Bylaws, or as may be otherwise required by applicable law: (i) in all matters other than the election of Directors, the affirmative vote of the holders of shares representing a majority of the votes present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the shareholders; (ii) each Director shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of such Director; and (iii) where a separate vote by a class or series is required, other than with respect to the election of Directors, the affirmative vote of the holders of shares of such class or series representing a majority of the votes present in person or represented by proxy at the meeting shall be the act of such class or series.

(b) Voting at meetings of shareholders need not be by written ballot and need not be conducted by inspectors of election unless so required by Section 1.9 of these Bylaws or so determined by the holders of stock having a majority of the votes which could be cast by the holders of all outstanding stock entitled to vote which are present in person or represented by proxy at such meeting.

(c) Stock of the Corporation belonging to the Corporation, or to another Corporation, a majority of the shares entitled to vote in the election of Directors of which are held by the Corporation, shall not be voted at any meeting of shareholders and shall not be counted in the total number of outstanding shares for the purpose of determining whether a quorum is present. Nothing in this Section 1.7 shall limit the right of the Corporation to vote shares of stock of the Corporation held by it in a fiduciary capacity.

Section 1.8 (a) Each shareholder entitled to vote at a meeting of shareholders may authorize another person or persons to act for such shareholder 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. 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 shareholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing with the Secretary an instrument in writing revoking the proxy or another duly executed proxy bearing a later date.

(a) A shareholder may authorize another person or persons to act for such shareholder as proxy (i) by executing a writing authorizing such person or persons to act as such, which execution may be accomplished by such shareholder or such shareholder’s authorized officer, Director, partner, employee or agent (or, if the stock is held in a trust or estate, by a trustee, executor or administrator thereof) signing such writing or causing his or her signature to be affixed to such writing by any reasonable means, including, but not limited to, facsimile signature, or (ii) by transmitting or authorizing the transmission of a telegram, cablegram or other means of electronic transmission (a “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 Transmission must either set forth or be submitted with information from which it can be determined that such Transmission was authorized by such shareholder.

(b) Any inspector or inspectors appointed pursuant to Section 1.9 of these Bylaws shall examine each Transmission to determine whether it is valid. If no inspector or inspectors are so appointed, the Secretary or such other person or persons as shall be appointed from time to time by the Board of Directors shall examine Transmissions to determine if they are valid. If it is determined a Transmission is valid, the person or persons making that determination shall specify the information upon which such person or persons relied. Any copy, facsimile telecommunication or other reliable reproduction of such a writing or Transmission may be substituted or used in lieu of the original writing or Transmission for any and all purposes for which the original writing or Transmission could be used; provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or Transmission.

Section 1.9 Voting Procedures and Inspectors of Elections. (a) Unless otherwise provided in the Certificate of Incorporation or required by law, the following provisions of this Section 1.9 shall apply only if and when the Corporation has a class of voting stock that is (i) listed on a national securities exchange, (ii) authorized for quotation on an interdealer quotation system of a registered national securities association or (iii) held of record by more than 2,000 shareholders.

(a) The Corporation shall, in advance of any meeting of shareholders, appoint one or more inspectors of election (individually an “inspector,” and collectively the “inspectors”) to act at such meeting and make a written report thereof. The Board of Directors may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at such meeting, the chairman of the meeting shall appoint one or more inspectors to act at the meeting. Each inspector of election, before entering upon the discharge of his duties, shall take and sign an oath to execute faithfully the duties of inspector with strict impartiality and according to the best of his ability.

(b) The inspectors shall (i) ascertain the number of shares of stock of the Corporation outstanding and the voting power of each, (ii) determine the number of shares of stock of the Corporation present in person or by proxy at such meeting and the validity of proxies and ballots, (iii) count all votes and ballots, (iv) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors and (v) certify their determination of the number of such shares present in person or by proxy at such meeting and their count of all votes and ballots. The inspectors may appoint or retain other persons or entities to assist them in the performance of their duties.

(c) The date and time of the opening and the closing of the polls for each matter upon which the shareholders will vote at a meeting shall be announced at such meeting. No ballots, proxies or votes, nor any revocations thereof or changes thereto, shall be accepted by the inspectors after the closing of the polls unless the Court of Chancery of the State of Delaware upon application by any shareholder shall determine otherwise.

(d) In determining the validity and counting of proxies and ballots, the inspectors shall be limited to an examination of the proxies, any envelopes submitted with such proxies, any information referred to in paragraphs (b) and (c) of Section 1.8 of these Bylaws, ballots and the regular books and records of the Corporation, except that the inspectors may consider other reliable information for the limited purpose of reconciling proxies and ballots submitted by or on behalf of banks, brokers, their nominees or similar persons which represent more votes than the holder of a proxy is authorized by a shareholder of record to cast or more votes than such shareholder holds of record. If the inspectors consider other reliable information for the limited purpose permitted herein, the inspectors, at the time they make their certification pursuant to paragraph (c) of this Section 1.9, shall specify the precise information considered by them, including the person or persons from whom such information was obtained, when and the means by which such information was obtained and the basis for the inspectors’ belief that such information is accurate and reliable.

Section 1.10 Fixing Date of Determination of Shareholders of Record. (a) In order that the Corporation may determine the shareholders entitled (i) to notice of or to vote at any meeting of shareholders or any adjournment thereof, (ii) to receive payment of any dividend or other distribution or allotment of any rights, (iii) to exercise any rights in respect of any change, conversion or exchange of stock or (iv) to take, receive or participate in any other action, the Board of Directors may fix a record date, which shall not be earlier than the date upon which the resolution fixing the record date is adopted by the Board of Directors and which (1) in the case of a determination of shareholders entitled to notice of or to vote at any meeting of shareholders or adjournment thereof, shall, unless otherwise required by law, be not more than 60 nor less than 10 days before the date of such meeting; and (2) in the case of any other action, shall be not more than 60 days before such action.

(a) If no record date is fixed, (i) the record date for determining shareholders entitled to notice of or to vote at a meeting of shareholders 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 shareholders 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.

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

Section 1.11 List of Shareholders Entitled to Vote. The Secretary shall prepare, at least 10 days before every meeting of shareholders, a complete list of the shareholders 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 shareholder. Such list shall be open to the examination of any shareholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, either at a place within the city where the meeting is to be held, which place shall be specified in the notice of meeting, or, if not so specified, at the place where the meeting is to be held. 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 shareholder who is present. The stock ledger shall be the only evidence as to who are the shareholders entitled to examine the stock ledger or to vote in person or by proxy at any meeting of shareholders.

Conversion shall be deemed to have been effected on the date when delivery of such written notice, accompanied by such certificate or other instrument, if any, is made, and such date is referred to herein as the Conversion Date. As promptly as practicable after the Conversion Date, the Corporation may issue and deliver to or upon the written order of such holder a certificate or other instrument, if any, representing the number of Series B-2 Memberships to which such holder is entitled as a result of the exercise of such conversion right. The person in whose name the certificates or other instruments representing Series B-2 Memberships are to be issued shall be deemed to have become the holder of record of such Series B-2 Memberships on the applicable Conversion Date.

(c) Memberships Reserved for Issuance. The Corporation shall take all actions necessary to reserve and make available at all times for issuance upon the conversion of Series B-3 Memberships, such number of Series B-2 Memberships as are issuable upon the conversion of all outstanding Series B-3 Memberships.

Subject to the terms and conditions of this Section E of Article IV, the Corporation shall maintain open outcry markets operating as of April 22, 2005 (the “Effective Date”) and provide financial support to each such market for technology, marketing and research, which the Board of Directors of the Corporation determines, in its sole and absolute discretion, is reasonably necessary to maintain each such open outcry market.

Notwithstanding the foregoing or any other provision of this Certificate of Incorporation, the Board of Directors of the Corporation may discontinue any open outcry market at such time and in such manner as it may determine if (1) the Board of Directors determines, in its sole and absolute discretion, that a market is no longer “liquid” or (2) the holders of a majority of the voting power of the then outstanding Series B-1 Memberships and Series B-2 Memberships, voting together as a single class based on their respective voting rights, approve the discontinuance of such open outcry market.

For purposes of the foregoing, an open outcry market will be deemed “liquid” for so long as it meets either of the following tests, in each case as measured on a quarterly basis:

(a) if a comparable exchange-traded product exists, the open outcry market has maintained at least 30 percent (30%) of the average daily volume of such comparable product (including for calculation purposes, volume from Exchange-For-Physicals transactions in such open outcry market); or

(b) if no comparable exchange-traded product exists, the open outcry market has maintained at least 40 percent (40%) of the average quarterly volume in that market as maintained by the Corporation in 2001 (including, for calculation purposes, volume from Exchange-For-Physicals transactions in such open outcry market).

The commitment to maintain open outcry markets set forth in this Section E of Article IV will not apply to markets introduced after the Effective Date.

F. Exercise Rights. Subject to the terms and conditions of this Section F of Article IV of this Certificate of Incorporation:

1. Each holder of record on the official books and records of the Corporation as of May 29, 2007 of (I) a Series B-1 Membership in respect of which an Exercise Right Privilege (as defined in Rule 210(b) of the Rules) is issuable but has not been issued or (II) both (a) one or more Exercise Right Privileges and (b) a Series B-1 Membership shall have the right, exercisable during the forty five (45) day period (the “Offer Period”) immediately following the effective time of the merger of CBOT Holdings, Inc. (“CBOT Holdings”) with and into Chicago Mercantile Exchange Holdings Inc. (“CME Holdings”) pursuant to the terms of that certain Agreement and Plan of Merger, dated as of October 17, 2006, as amended, among the Corporation, CBOT Holdings and CME Holdings, to sell any such Exercise Right Privilege to the Corporation for an amount equal to $250,000 in cash (a “Purchase Offer”).

The Corporation shall make payment as provided in this Section F.1 to a holder who makes the required delivery of the Exercise Right Privilege and Assignment Agreement within thirty (30) days after the expiration of the Offer Period.

2. In the event of a Final Resolution (as defined below) pursuant to which the Class Members (as defined below) receive a recovery of cash, marketable securities or other property or rights with respect to each Exercise Right Privilege held by a Class Member and/or retain or are declared to have property or rights with respect to each Exercise Right Privilege held by a Class Member (collectively, a “Per ERP Recovery”) with an aggregate Fair Market Value (as defined below) less than $250,000, the Corporation shall pay to each such Class Member with respect to each such Exercise Right Privilege held by such Class Member an amount equal to the difference between $250,000 and the Fair Market Value of the Per ERP Recovery so received or retained, as applicable, by such Class Member with respect to such Exercise Right Privilege held by such Class Member (a “Balance Payment”). In order for a Class Member to receive a Balance Payment with respect to an Exercise Right Privilege, such Class Member must provide evidence reasonably satisfactory to the Corporation that such Class Member received the Per ERP Recovery pursuant to the Final Resolution with respect to such Exercise Right Privilege. The Corporation shall make payment to such holder prior to the later of (i) thirty (30) days after delivery of the sufficient evidence contemplated by the immediately preceding sentence or (ii) thirty (30) days after the date the Fair Market Value of the Per ERP Recovery is determined in accordance with the terms of Section 5(e) of this Section F of Article IV of this Certificate of Incorporation.

3. In the event of the entry of a Zero Judgment (as defined below), the Corporation will pay to each Non-Recovery Class Member (as defined below) $250,000 for each Exercise Right Privilege held by such Non-Recovery Class Member. The Corporation shall make payment to a Non-Recovery Class Member within thirty (30) days after the date the such person’s status as a Non-Recovery Class Member is determined in accordance with the terms of Section 5(g) of this Section F of Article IV of this Certificate of Incorporation.

4. Notwithstanding anything to the contrary contained in this Section F of this Article IV of this Certificate of Incorporation, in no event shall the Corporation be required to pay in excess of $250,000 in respect of any single Exercise Right Privilege.

(c) “Court” means the Delaware Chancery Court presiding over the CBOE Litigation;

(d) “Complaint” means the complaint on file with the Court setting forth the claims in the CBOE Litigation as of the time of the Final Resolution;
