employment with the Company and its affiliates. 
 NOW, THEREFORE, in consideration of the above premises and the following mutual covenants
and conditions, the parties agree as follows: 
 1. Resignation from Offices. Executive and the Company agree that Executive’s
resignation as Executive Vice President and General Counsel of the Company and her resignation from all other positions (including any positions as a fiduciary or otherwise with respect to any employee benefit plan) she has held with the Company and

Executive the following amounts with respect to 2005: 
  

	 	(i)	A bonus amount of $200,000 

  

	 	(ii)	A supplemental retirement payment of $283,560 representing the portion of Executive’s 2005 excess 401(k) benefit that was not paid prior to her Retirement Date and her

 (c) Supplemental Payment. In recognition of the substantial contributions which Executive has made
to the Company, including the restructuring of CBOT and the initial public offering of Holdings, and in consideration of the release set forth in Section 5 hereof, the Company shall pay to Executive a supplemental payment in the amount of
$500,000. Executive shall receive the supplemental payment in one lump sum no later than 5 business days after the expiration of the revocation period referred to in Section 5 hereof. Executive agrees that such consideration is in addition to
anything of value to which she is already entitled. 
 (d) Medical and Similar Benefits. Executive shall be entitled to life, medical

right to receive at her election post-employment insurance coverage at her cost in accordance with the terms of her employment agreement with the CBOT dated May 18, 1999, as amended. Executive shall be entitled to any conversion right or COBRA

the Company’s common stock pursuant to a Non-Qualified Stock Option Award granted October 18, 2005 (the “Option Agreement”) has terminated in full without any portion thereof vesting. Nonetheless, the Company agrees to make a
payment to Executive on the first business day in 2007 in an amount equal to the product of 5,000 times the excess of (i) the officially quoted closing selling price of a share of Holdings common stock on the New York Stock Exchange on the last
trading day occurring on or before October 18, 2006 over (ii) $54.00. 
 (f) Retirement Benefit Plans. Executive shall be
entitled to receive a qualified pension benefit, and shall be entitled to all payment options available to her, in accordance with the terms of the Chicago Board of Trade Employees Pension Plan and shall be entitled to receive her account balance,

excess of $100,000 for Executive’s attorneys fees and outplacement costs. 
 (h) Other. Except as expressly provided in this
Agreement, no other sums (contingent or otherwise) shall be paid to Executive in respect of her employment by the Company, and any such sums (whether or not owed) are hereby expressly waived by Executive.

 4. Tax Withholding and Reporting. The Company shall be entitled to withhold from the benefits and
payments described herein all income and employment taxes it determines to be necessary to satisfy all tax withholding obligations. The parties hereto do not believe that any payments or benefits under this Agreement are subject to additional tax

Executive’s status as an officer, director or employee of the Company or any of said entities or the termination of that status or involving any matter occurring from the beginning of Executives’ employment with the Company and its
affiliates to the date of these presents, or involving any continuing effects of any actions or practices which may have arisen or occurred from the beginning of such employment to the date of these presents; provided, however, that this

officer or employee of the Company or was serving at the request of the Company as director officer, member, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee
benefit plans, whether or not the basis of such Proceeding is Executive’s alleged action in an official capacity while serving as director, officer, member, employee or agent, Executive shall be indemnified and held harmless by the Company to
the fullest extent permitted or authorized by the Company’s certificate of incorporation and bylaws (and shall be entitled to advancements in accordance with such bylaws) against all cost, expense, liability and loss (including without

 (b) The Company agrees to continue to cover Executive under its directors’ and officers’ liability insurance and employment

 Either party may change her or its address or the name of the person to whose attention the notice or other communication
shall be directed from time to time by serving notice thereof upon the other party as provided herein. 
 15. Governing Law. This
Agreement, and the rights and obligations of the parties hereto, shall be governed by and construed in accordance with the laws of the State of Illinois, without regard to principles of the conflicts of laws. If any provision hereof is
unenforceable, such provision shall be fully severable, and this Agreement shall be construed and enforced as if such unenforceable provision had never comprised a part hereof, the remaining provisions hereof shall remain in full force and effect,
and the court construing the Agreement shall add as a part hereof a provision as similar in terms and effect to such unenforceable provision as may be enforceable, in lieu of the unenforceable provision. 
 16. Prior Agreements. This Agreement sets forth the entire agreement between the parties hereto, and fully supersedes any and all prior oral or
written agreements between the parties pertaining to the subject matter hereof and, without limitation, but subject to Sections 2(d) and 10 above, supersedes her executive employment agreement with the CBOT dated May 18, 1999, as amended.

 17. Reimbursement. If Executive or her heirs, executors, administrators, successors or assigns (a) breaches Sections 6 or 10
of this Agreement, or (b) attempts to challenge the enforceability of this Agreement, or (c) files a charge of discrimination, a lawsuit, or a claim of any kind for any matter released herein, all further payments and benefits owed under
Section 2 of the Agreement shall terminate and Executive or her heirs, executors, administrators, successors or assigns shall be obligated to tender back to the Company all payments made to her or them under Section 2 of this Agreement,
and to indemnify and hold harmless the Company from and against all liability, costs and expenses, including attorneys’ fees, arising out of said breach, challenge or action by Executive, her heirs, executors, administrators, successors or
assigns. 
 18. Waiver of Breach. The waiver by Executive or the Company of a breach of any provision of this Agreement shall not
operate as or be deemed a waiver of any subsequent breach by Executive or the Company. Continuation of benefits hereunder by the Company following a breach by Executive of any provision of this Agreement shall not preclude the Company from
thereafter exercising any right that it may otherwise independently have to terminate said benefits based upon the same violation. 
 19.
Counterparts. This Agreement may be executed in more than one counterpart, but all of which together will constitute one and the same agreement. 
 20. Successors and Assigns. This Agreement shall be binding upon the successors and assigns of the Company and Executive. In the event of the death of Executive, any payments remaining due hereunder shall be
paid to Executive’s estate.

AGREEMENT CONTAINS A RELEASE OF ALL KNOWN AND
