 This agreement (as amended, supplemented or otherwise modified and in effect from time to time, the
“Agreement”) sets forth the understandings between the Issuer and the Dealer, each named on the cover page hereof, in connection with the issuance and sale by the Issuer of its short-term promissory notes (the “Notes”) through
the Dealer. 
 Certain terms used in this Agreement are defined in Section 6 hereof. 
 The Addendum to this Agreement, and any Annexes or Exhibits described in this Agreement or such Addendum, are hereby incorporated into this Agreement and made fully a part hereof. 
  

	1.	Offers, Sales and Resales of Notes. 

  

	 	1.1	While (i) the Issuer has and shall have no obligation to sell the Notes to the Dealer or to permit the Dealer to arrange any sale of the Notes for the account of the Issuer,
and (ii) the Dealer has and shall have no obligation to purchase the Notes from the Issuer or to arrange any sale of the Notes for the account of the Issuer, the parties hereto agree that in any case where the Dealer purchases Notes from the
Issuer, or arranges for the sale of Notes by the Issuer, such Notes will be purchased or sold by the Dealer in reliance on the representations, warranties, covenants and agreements of the Issuer contained herein or made pursuant hereto and on the
terms and conditions and in the manner provided herein. 

  

	 	1.2	So long as this Agreement shall remain in effect, and in addition to the limitations contained in Section 1.7 hereof, the Issuer shall not, without the consent of the Dealer,
offer, solicit or accept offers to purchase, or sell, any Notes except (a) in transactions with one or more dealers which may from time to time after the date hereof become dealers with respect to the Notes by executing with the Issuer one or
more agreements which contain provisions substantially identical to those contained in Section 1 of this Agreement, of which the Issuer hereby undertakes to provide the Dealer prompt notice or (b) in transactions with the other dealers
listed on the Addendum hereto, which are executing agreements with the Issuer which contain provisions substantially identical to Section 1 of this Agreement contemporaneously herewith. In no event shall the Issuer offer, solicit or accept
offers to purchase, or sell, any Notes directly on its own behalf in transactions with persons other than broker-dealers as specifically permitted in this Section 1.2. 

  

	 	1.3	The Notes shall be in a minimum denomination of $250,000 or integral multiples of $1,000 in excess thereof, will bear such interest rates, if interest bearing, or will be sold at
such discount from their face amounts, as shall be agreed upon by the Dealer and the Issuer, shall have a maturity not exceeding 397 days from the date of issuance and may have such terms as are specified in Exhibit C hereto or the Private Placement
Memorandum. The Notes shall not contain any provision for extension, renewal or automatic “rollover.” 

  

	 	1.4	The authentication and issuance of, and payment for, the Notes shall be effected in accordance with the Issuing and Paying Agency Agreement, and the Notes shall be either individual
physical certificates or book-entry notes evidenced by one or more master notes (each, a “Master Note”) registered in the name of The Depository Trust Company (“DTC”) or its nominee.

Program    n    2 

	 	1.5	If the Issuer and the Dealer shall agree on the terms of the purchase of any Note by the Dealer or the sale of any Note arranged by the Dealer (including, but not limited to,
agreement with respect to the date of issue, purchase price, principal amount, maturity and interest rate or interest rate index and margin (in the case of interest-bearing Notes) or discount thereof (in the case of Notes issued on a discount
basis), and appropriate compensation for the Dealer’s services hereunder) pursuant to this Agreement, the Issuer shall cause such Note to be issued and delivered in accordance with the terms of the Issuing and Paying Agency Agreement and
payment for such Note shall be made by the purchaser thereof, either directly or through the Dealer, to the Issuing and Paying Agent, for the account of the Issuer. Except as otherwise agreed, in the event that the Dealer is acting as an agent of
the Issuer and a purchaser shall either fail to accept delivery of or make payment for a Note on the date fixed for settlement, the Dealer shall promptly notify the Issuer, and if the Dealer has theretofore paid the Issuer for the Note, the Issuer
will promptly return such funds to the Dealer against its return of the Note to the Issuer, in the case of a certificated Note, and upon notice of such failure in the case of a book-entry Note. If such failure occurred for any reason other than
default by the Dealer, the Issuer shall reimburse the Dealer on an equitable basis for the Dealer’s loss of the use of such funds for the period such funds were credited to the Issuer’s account. 

  

	 	1.6	The Dealer and the Issuer hereby establish and agree to observe the following procedures in connection with offers, sales and subsequent resales or other transfers of the Notes:

  

	 	(a)	Offers and sales of the Notes by or through the Dealer shall be made by the Dealer only to: (i) investors reasonably believed by the Dealer to be Qualified Institutional Buyers
or Institutional Accredited Investors and (ii) non-bank fiduciaries or agents that will be purchasing Notes for one or more accounts, each of which is reasonably believed by the Dealer to be an Institutional Accredited Investor.

  

	 	(b)	Resales and other transfers of the Notes by the holders thereof shall be made only in accordance with the restrictions in the legend described in clause (e) below.

  

	 	(c)	No general solicitation or general advertising shall be used in connection with the offering of the Notes. Without limiting the generality of the foregoing, the Issuer shall not
issue any press release or place or publish any “tombstone” or other advertisement relating to the Notes without promptly providing notice to the Dealer. The Dealer shall not issue any press release or publish any “tombstone” or
other advertisement relating to the Notes without the prior written consent of the Issuer. 

  

	 	(d)	No sale of Notes to any one purchaser shall be for less than $250,000 principal or face amount, and no Note shall be issued in a smaller principal or face amount. If the purchaser
is a non-bank fiduciary acting on behalf of others, each person for whom such purchaser is acting must purchase at least $250,000 principal or face amount of Notes. 

  

	 	(e)	Offers and sales of the Notes by the Issuer through the Dealer acting as agent for the Issuer shall be made in accordance with Rule 506 under the Securities Act, and shall be
subject to the restrictions described in the legend appearing on Exhibit A hereto. A legend substantially to the effect of such Exhibit A shall appear as part of the Private Placement Memorandum used in connection with offers and sales of Notes
hereunder, as well as on each individual certificate representing a Note and each Master Note representing book-entry Notes offered and sold pursuant to this Agreement.

	 	(f)	The Dealer shall furnish or shall have furnished to each purchaser of Notes for which it has acted as the Dealer a copy of the then-current Private Placement Memorandum unless such
purchaser has previously received a copy of the Private Placement Memorandum as then in effect. The Private Placement Memorandum shall expressly state that any person to whom Notes are offered shall have an opportunity to ask questions of, and
receive information from, the Issuer and the Dealer and shall provide the names, addresses and telephone numbers of the persons from whom information regarding the Issuer may be obtained. 

  

	 	(g)	The Issuer agrees, for the benefit of the Dealer and each of the holders and prospective purchasers from time to time of the Notes that, if at any time the Issuer shall not be
subject to Section 13 or 15(d) of the Exchange Act, the Issuer will furnish, upon request and at its expense, to the Dealer and to holders and prospective purchasers of Notes information required by Rule 144A(d)(4)(i) in compliance with Rule
144A(d). 

  

	 	(h)	In the event that any Note offered or to be offered by the Dealer would be ineligible for resale under Rule 144A, the Issuer shall immediately notify the Dealer (by telephone,
confirmed in writing) of such fact and shall promptly prepare and deliver to the Dealer an amendment or supplement to the Private Placement Memorandum describing the Notes that are ineligible, the reason for such ineligibility and any other relevant
information relating thereto. 

  

	 	(i)	Dealer hereby agrees with the Issuer not to offer or sell any Notes in a manner that might call into question the availability of the private offering exemption contained in
Section 4(2) of the Securities Act and Rule 144A thereunder. 

  

	 	1.7	The Issuer hereby represents and warrants to the Dealer, in connection with offers, sales and resales of Notes, as follows: 

  

	 	(a)	The Issuer hereby confirms to the Dealer that within the preceding six months, neither the Issuer nor any person other than the Dealer or the other dealers referred to in
Section 1.2 hereof acting on behalf of the Issuer has offered or sold any Notes, or any substantially similar security of the Issuer (including, without limitation, medium-term notes issued by the Issuer), to, or solicited offers to buy any
such security from, any person other than the Dealer or the other dealers referred to in Section 1.2 hereof. The Issuer also agrees that (except as permitted by Section 1.6(i)), as long as the Notes are being offered for sale by the Dealer
and the other dealers referred to in Section 1.2 hereof as contemplated hereby and until at least six months after the offer of Notes hereunder has been terminated, neither the Issuer nor any person other than the Dealer or the other dealers
referred to in Section 1.2 hereof (except as contemplated by Section 1.2 hereof) will offer the Notes or any substantially similar security of the Issuer for sale to, or solicit offers to buy any such security from, any person other than
the Dealer or the other dealers referred to in Section 1.2 hereof, it being understood that such agreement is made with a view to bringing the offer and sale of the Notes within the exemption provided by Section 4(2) of the Securities Act
and Rule 506 thereunder and shall survive any termination of this Agreement. The Issuer hereby represents and warrants that it has not taken or omitted to take, and will not take or omit to take, any action that would cause the offering and sale of
Notes hereunder to be integrated with any other offering of securities, whether such offering is made by the Issuer or some other party or parties. 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    4 

	 	(b)	Except with previous notification to the Dealer, the Issuer represents and agrees that the proceeds of the sale of the Notes are not currently contemplated to be used for the
purpose of buying, carrying or trading securities within the meaning of Regulation T and the interpretations thereunder by the Board of Governors of the Federal Reserve System. The Issuer will use the net proceeds from the sale of the Notes to fund
the tender offer for certain shares of the Issuer’s common stock, fees and expenses relating to the tender offer and to the Issuer’s merger with CBOT Holdings Inc. and for other general corporation purposes. Except as set forth in the
preceding sentence, in the event that the Issuer determines to use such proceeds for the purpose of buying, carrying or trading securities, whether in connection with an acquisition of another company or otherwise, the Issuer shall give the Dealer
at least five business days’ prior written notice to that effect. The Issuer shall also give the Dealer prompt notice of the actual date that it commences to purchase such securities with the proceeds of the Notes. Thereafter, in the event that
the Dealer purchases Notes as principal and does not resell such Notes on the day of such purchase, to the extent necessary to comply with Regulation T and the interpretations thereunder, the Dealer will sell such Notes either (i) only to
offerees it reasonably believes to be Qualified Institutional Buyers or to Qualified Institutional Buyers it reasonably believes are acting for other Qualified Institutional Buyers, in each case in accordance with Rule 144A or (ii) in a manner
which would not cause a violation of Regulation T and the interpretations thereunder. 

  

	 	1.8	The Dealer hereby agrees with the Issuer that the Dealer will not offer or sell any Notes in a manner that contradicts, in any material respect, the Issuer Information.

  

	2.	Representations and Warranties of Issuer. 

 The
Issuer represents and warrants that each acceptance by the Issuer of an offer for the purchase of Notes shall be deemed an affirmation by the Issuer that its representations and warranties set forth in this Article 2 are true and correct at the time
of such acceptance: 
  

	 	2.1	The Issuer is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all the requisite power and
authority to execute, deliver and perform its obligations under the Notes, this Agreement and the Issuing and Paying Agency Agreement. 

  

	 	2.2	This Agreement and the Issuing and Paying Agency Agreement have been duly authorized, executed and delivered by the Issuer and constitute legal, valid and binding obligations of the
Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general principles of equity
(regardless of whether enforcement is sought in a proceeding in equity or at law). 

  

	 	2.3	The Notes have been duly authorized, and when issued as provided in the Issuing and Paying Agency Agreement, will be duly and validly issued and will constitute legal, valid and
binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general
principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

offer and sale of the Notes. 

  

	 	2.7	Neither the execution and delivery of this Agreement and the Issuing and Paying Agency Agreement, nor the issuance of the Notes in accordance with the Issuing and Paying Agency
Agreement, nor the fulfillment of or compliance with the terms and provisions hereof or thereof by the Issuer, will (i) result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever upon any of the
properties or assets of the Issuer, or (ii) violate or result in a breach or a default under any of the terms of the Issuer’s charter documents or by-laws, any contract or instrument to which the Issuer is a party or by which it or its
property is bound, or any law or regulation, or any order, writ, injunction or decree of any court or government instrumentality, to which the Issuer is subject or by which it or its property is bound, which breach or default might have a material
adverse effect on the ability of the Issuer to perform its obligations under this Agreement, the Notes or the Issuing and Paying Agency Agreement. 

  

	 	2.8	There is no litigation or governmental proceeding pending, or to the knowledge of the Issuer threatened, against or affecting the Issuer or any of its subsidiaries which might

forth in this Section 2 remain true and correct on and as of such date as

if made on and as of such date, (ii) in the case of an issuance of Notes, the Notes being issued on such date have been duly and validly issued and
constitute legal, valid and binding obligations of the Issuer, enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and subject, as to
enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law), (iii) in the case of an issuance of Notes, since the date of the most recent Private Placement Memorandum, there

of such change, development or occurrence. 

  

	 	3.3	The Issuer shall from time to time furnish to the Dealer such public information as the Dealer may reasonably request regarding (i) the Issuer’s operations and financial
condition, (ii) the due authorization and execution of the Notes and (iii) the Issuer’s ability to pay the Notes as they mature. 

  

	 	3.4	The Issuer will take all such action as the Dealer may reasonably request to ensure that each offer and each sale of the Notes will comply with any applicable state Blue Sky laws;

business in any jurisdiction in which it is not otherwise so subject.

Memorandum, as amended or supplemented, shall not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not

 (c) In the event that (i) the Issuer gives
the Dealer notice pursuant to Section 4.3(a), (ii) the Dealer does not notify the Issuer that it is then holding Notes in inventory and (iii) the Issuer chooses not to promptly amend or supplement the Private Placement Memorandum in

sought to be charged with any liability shall contribute to the aggregate costs in connection with any Claim in the proportion of their respective economic interests; provided, however, that such contribution by the Issuer shall be in an amount such

 Model Opinion of Counsel to Issuer 
 [Company Letterhead] 
 August 16, 2007 
 To the Addressees listed on 
 Schedule I hereto 
 Ladies and Gentlemen: 
 I am the General Counsel of CME Group
Inc., a Delaware corporation (the “Company”), and, as such, I am furnishing this opinion in connection with each of (i) that certain Commercial Paper Dealer Agreement, dated as of August 16, 2007 (the “Lehman
Dealer Agreement”), between the Company, as issuer, and Lehman Brothers Inc., as dealer (the “Lehman Dealer”), (ii) that certain Commercial Paper Dealer Agreement, dated as of August 16, 2007 (the “Merrill
Dealer Agreement” and, together with the Lehman Dealer Agreement, collectively, the “Dealer Agreements”), among the Company, as issuer, and Merrill Lynch Money Markets Inc., as dealer for Notes (as defined in the Merrill
Dealer Agreement) with maturities up to 270 days (“MLMM”), and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as dealer for Notes (as defined in the Merrill Dealer Agreement) with maturities over 270 days
(“MLPF&S” and, together with MLMM, collectively, the “Merrill Dealer”), (iii) that certain Issuing and Paying Agency Agreement, dated as of August 16, 2007 (the “Issuing and Paying Agency
Agreement”), between the Company and JPMorgan Chase Bank, National Association, as issuing and paying agent (the “Issuing and Paying Agent”), and (iv) the Master Note dated August 16, 2007 (the “Master
Note”). The Lehman Dealer Agreement, the Merrill Dealer Agreement, the Issuing and Paying Agency Agreement and the Master Note shall hereafter be referred to collectively as the “Transaction Agreements.” This opinion is
being delivered pursuant to Section 3.6 of each Dealer Agreement. 
 In my examination, I have assumed the genuineness of all
signatures, including endorsements, the legal capacity and competency of natural persons, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic,
certified or photostatic copies, and the authenticity of the originals of such copies. When relevant facts were not independently established, I have relied upon statements of governmental officials and upon representations made in or pursuant to
the Transaction Agreements, certificates of appropriate representatives of the Company. 
 In rendering the opinions set forth herein, I have
examined and relied upon originals or copies of the Transaction Agreements and such other documents as I have deemed necessary or appropriate as a basis for the opinions set forth below. 
 Capitalized terms used herein and not otherwise defined herein shall have the same meanings herein as ascribed thereto in the Dealer Agreements. As used
herein, “Applicable Laws” means those laws, rules and regulations which, in my experience, are normally applicable to transactions of the type contemplated by the Transaction Agreements, without my having made any special
investigation as to the applicability of any specific law, rule or regulation, and which are not the subject of a specific opinion herein referring expressly to a particular law or laws. 
 I am a member of the Bar of the State of Illinois and the foregoing opinions are limited to matters involving the Federal laws of the United States of
America and the General Corporation Law of 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    15 

 
the State of Delaware and I do not express any opinion as to any other laws. I note that the Transaction Agreements purport to be governed by the laws of the
State of New York and I express no opinion with respect to the laws of the State of New York. 
 Based upon the foregoing and subject to the
limitations, qualifications, exceptions and assumptions set forth herein, I am of the opinion that: 
 1. The Company is a corporation validly
existing and in good standing under the laws of the State of Delaware. 
 2. The Company has all the requisite corporate power and authority
to execute, deliver and perform its obligations under each of the Transaction Agreements. The execution and delivery of each of the Transaction Agreements and the consummation by the Company of the transactions contemplated thereby have been duly
authorized by all requisite corporate action on the part of the Company. Each of each Dealer Agreement and the Issuing and Paying Agency Agreement has been duly executed and delivered by the Company. 
 3. In the event that an Illinois court were to apply the substantive laws of the State of Illinois, notwithstanding the choice of law of the parties set
forth in the Transaction Agreements, and without regard to choice of law principles, each of the Transaction Agreements constitutes and, in the case of the Notes, when issued in accordance with the Issuing and Paying Agency Agreement and paid for by
the purchasers thereof, will constitute, the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms under the Applicable Laws of the State of Illinois. 
 4. The execution and delivery by the Company of each of the Transaction Agreements and the performance by the Company of its obligations under each of
the Transaction Agreements, each in accordance with its terms, do not (i) conflict with the certificate of incorporation or by-laws of the Company, (ii) constitute a violation of, or a default under any material agreements or instruments
known to me (after due inquiry) to which the Company is a party or by which it is bound or to which it is subject or result in the creation or imposition of any lien upon any property of the Company pursuant to the terms of any such material
agreement or instrument or (iii) violate any order, writ, injunction or decree known to me (after due inquiry) of any court or governmental authority or agency applicable to the Company. 
 5. The offer, sale and delivery of the Notes in the manner contemplated by the Dealer Agreements do not require registration under the Securities Act of
1933, as amended, or qualification of any indenture under the Trust Indenture Act of 1939, as amended (it being understood that I express no opinion as to any subsequent resale of any Note); and the Notes will rank at least pari passu with
all other unsecured and unsubordinated indebtedness of the Company. 
 6. No consent, approval or authorization of, or filing, recording or
registration with, any governmental authority, which has not been obtained or taken and is not in full force and effect, is required to authorize, or is required in connection with, the execution or delivery of any of the Transaction Agreements by
the Company or the enforceability of any of the Transaction Agreements against the Company, except as may be required by the securities or Blue Sky laws of the various states in connection with the offer and sale of the Notes. 
 7. To the best of my knowledge, except as disclosed in the Company’s public filings with the Securities and Exchange Commission, there is no
litigation or governmental proceeding pending or threatened against the Company or any of its subsidiaries which would have a material adverse effect on the ability of the Company to perform its obligations under the Transaction Agreements.

 8. The Company is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended. 

 

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    16 

 My opinions are subject to the following assumptions and qualifications: 
 (a) enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting creditors’ rights
generally and by general principles of equity (regardless of whether enforcement is sought in equity or at law); 
 (b) I have assumed that
each of the Transaction Agreements constitutes the valid and binding obligation of each party to such Transaction Agreement (other than the Company to the extent expressly set forth herein) enforceable against such other party in accordance with its
terms; 
 (c) I express no opinion as to the effect on the opinions expressed herein of (i) the compliance or non-compliance of any
party (other than the Company to the extent expressly set forth herein) to the Transaction Agreements with any state, federal or other laws or regulations applicable to any of them or (ii) the legal or regulatory status or the nature of the
business of any party (other than the Company to the extent expressly set forth herein); 
 (d) I express no opinion as to the enforceability
of any rights to contribution or indemnification provided for in the Transaction Agreements which are violative of the public policy underlying any law, rule or regulation (including any federal or state securities law, rule or regulation);

 (e) I express no opinion as to the applicability or effect of any fraudulent transfer, preference or similar law on the Transaction
Agreements or any transactions contemplated thereby; 
 (f) I express no opinion on the enforceability of any provision in a Transaction
Agreement purporting to prohibit, restrict or condition the assignment of rights under such Transaction Agreement to the extent such restriction on assignability is governed by the Uniform Commercial Code; 
 (g) I express no opinion as to the enforceability of any provision of any Transaction Agreement to the extent it purports to waive any objection a person
may have that a suit, action or proceeding has been brought in an inconvenient forum or a forum lacking subject matter jurisdiction; 
 (h)
for purposes of my opinion set forth in paragraph 5 above, I have assumed (a) the accuracy of the representations and warranties and compliance with the agreements made by the Dealer in the Dealer Agreements (b) compliance by the Dealer
with the offering and transfer procedures and restrictions required by the Dealer Agreements including, without limitation, the delivery to each purchaser of the Notes of an offering memorandum containing a legend restricting offers, sales and
resales of the Notes in the form required by the Dealer Agreements and (c) the accuracy of the representations and warranties made in accordance with such offering memorandum by the initial purchasers of the Notes; and 
 (i) I express no opinion as to the enforceability of Section 7.3(a) of either Dealer Agreement. 
 At the request of the Company, this opinion letter is, pursuant to Section 3.6 of each Dealer Agreement, provided to you by me in my capacity as
in-house counsel of the Company and may not be relied upon by any person for any purpose other than in connection with the transactions contemplated by the Transaction Agreements without, in each instance, my prior written consent. No opinion is
implied or is to be inferred beyond the opinions expressly stated above. I assume no obligation to update this letter for events, changes in law or circumstances occurring after the date of this opinion. 
 Very truly yours,

 Exhibit B 
 Further
Provisions Relating to Indemnification 
  

	(a)	The Issuer agrees to reimburse each Lehman Indemnitee for all reasonable expenses (including reasonable fees and disbursements of external counsel) as they are incurred by it in
connection with investigating or defending any loss, claim, damage, liability or action in respect of which indemnification may be sought under Section 5.1 of the Agreement (whether or not it is a party to any such proceedings).

  

	(b)	Promptly after receipt by a Lehman Indemnitee of notice of the existence of a Claim arising under Section 5.1 of the Agreement, such Lehman Indemnitee will, if a claim in
respect thereof is to be made against the Issuer, notify the Issuer in writing of the existence thereof; provided that (i) the omission so to notify the Issuer will not relieve the Issuer from any liability which it may have hereunder unless
and except to the extent it did not otherwise learn of such Claim and such failure results in the forfeiture by the Issuer of substantial rights and defenses, and (ii) the omission so to notify the Issuer will not relieve it from liability
which it may have to a Lehman Indemnitee otherwise than on account of this indemnity agreement. In case any such Claim is made against any Lehman Indemnitee and it notifies the Issuer of the existence thereof, the Issuer will be entitled to
participate therein, and to the extent that it may elect by written notice delivered to the Lehman Indemnitee, to assume the defense thereof, with counsel reasonably satisfactory to such Lehman Indemnitee; provided that if the defendants in any such
Claim include both the Lehman Indemnitee and the Issuer, and the Lehman Indemnitee shall have concluded that there may be legal defenses available to it which are different from or additional to those available to the Issuer, the Issuer shall not
have the right to direct the defense of such Claim on behalf of such Lehman Indemnitee, and the Lehman Indemnitee shall have the right to select separate counsel to assert such legal defenses on behalf of such Lehman Indemnitee. Upon receipt of
notice from the Issuer to such Lehman Indemnitee of the Issuer’s election so to assume the defense of such Claim and approval by the Lehman Indemnitee of counsel, the Issuer will not be liable to such Lehman Indemnitee for expenses incurred
thereafter by the Lehman Indemnitee in connection with the defense thereof (other than reasonable costs of investigation) unless (i) the Lehman Indemnitee shall have employed separate counsel in connection with the assertion of legal defenses
in accordance with the proviso to the next preceding sentence (it being understood, however, that the Issuer shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel in the jurisdiction in which any
Claim is brought), approved by the Dealer, representing the Lehman Indemnitee who is party to such Claim), (ii) the Issuer shall not have employed counsel reasonably satisfactory to the Lehman Indemnitee to represent the Lehman Indemnitee
within a reasonable time after notice of existence of the Claim or (iii) the Issuer has authorized in writing the employment of counsel for the Lehman Indemnitee. The indemnity, reimbursement and contribution obligations of the Issuer hereunder
shall be in addition to any other liability the Issuer may otherwise have to a Lehman Indemnitee and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Issuer and any Indemnitee. The
Issuer agrees that without the Dealer’s prior written consent, it will not settle, compromise or consent to the entry of any judgment in any Claim in respect of which indemnification may be sought under the indemnification provision of the
Agreement (whether or not the Dealer or any other Indemnitee is an actual or potential party to such Claim), unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnitee from all liability arising out
of such Claim and (ii) does not include a statement as to or an admission of fault, culpability or failure to act, by or on behalf of any Indemnitee.

	(c)	The Dealer agrees to reimburse each Issuer Indemnitee for all reasonable expenses (including reasonable fees and disbursements of external counsel) as they are incurred by it in
connection with investigating or defending any loss, claim, damage, liability or action in respect of which indemnification may be sought under Section 5.2 of the Agreement (whether or not it is a party to any such proceedings).

  

	(d)	Promptly after receipt by an Issuer Indemnitee of notice of the existence of a Claim arising under Section 5.2 of the Agreement, such Issuer Indemnitee will, if a claim in
respect thereof is to be made against the Dealer, notify the Dealer in writing of the existence thereof; provided that (i) the omission so to notify the Dealer will not relieve the Dealer from any liability which it may have hereunder unless
and except to the extent it did not otherwise learn of such Claim and such failure results in the forfeiture by the Dealer of any of its rights and defenses that it reasonably deems to be material, and (ii) the omission so to notify the Dealer
will not relieve it from liability which it may have to an Issuer Indemnitee otherwise than on account of this indemnity agreement. In case any such Claim is made against any Issuer Indemnitee and it notifies the Dealer of the existence thereof, the
Dealer will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the Issuer Indemnitee, to assume the defense thereof, with counsel reasonably satisfactory to such Issuer Indemnitee; provided that if
the defendants in any such Claim include both the Issuer Indemnitee and the Dealer, and the Issuer Indemnitee shall have concluded that there may be legal defenses available to it which are different from or additional to those available to the
Dealer, the Dealer shall not have the right to direct the defense of such Claim on behalf of such Issuer Indemnitee, and the Issuer Indemnitee shall have the right to select separate counsel to assert such legal defenses on behalf of such Issuer
Indemnitee. Upon receipt of notice from the Dealer to such Issuer Indemnitee of the Dealer’s election so to assume the defense of such Claim and approval by the Issuer Indemnitee of counsel, the Dealer will not be liable to such Issuer
Indemnitee for expenses incurred thereafter by the Issuer Indemnitee in connection with the defense thereof (other than reasonable costs of investigation) unless (i) the Issuer Indemnitee shall have employed separate counsel in connection with
the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the Dealer shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel in
the jurisdiction in which any Claim is brought), approved by the Issuer, representing the Issuer Indemnitee who is party to such Claim), (ii) the Dealer shall not have employed counsel reasonably satisfactory to the Issuer Indemnitee to

obligations of the Dealer hereunder shall be in addition to any other liability the Dealer may otherwise have to an Issuer Indemnitee and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives
of the Dealer and any Issuer Indemnitee. The Dealer agrees that without the Issuer’s prior written consent, it will not settle, compromise or consent to the entry of any judgment in any Claim in respect of which indemnification may be sought
under the indemnification provision of the Agreement (whether or not the Issuer or any other Indemnitee is an actual or potential party to such Claim), unless such settlement, compromise or consent (i) includes an unconditional release of each
Indemnitee from all liability arising out of such Claim and (ii) does not include a statement as to or an admission of fault, culpability or failure to act, by or on behalf of any Indemnitee.

 Exhibit C 
 Statement of Terms for Interest – Bearing Commercial Paper Notes of CME Group Inc. 
 THE PROVISIONS SET FORTH BELOW ARE QUALIFIED TO
THE EXTENT APPLICABLE BY THE TRANSACTION SPECIFIC [PRICING] [PRIVATE PLACEMENT MEMORANDUM] SUPPLEMENT (THE “SUPPLEMENT”) (IF ANY) SENT TO EACH PURCHASER AT THE TIME OF THE TRANSACTION. 
  

	 	1.	General. (a) The obligations of the Issuer to which these terms apply (each a “Note”) are represented by one or more Master Notes (each, a “Master
Note”) issued in the name of (or of a nominee for) The Depository Trust Company (“DTC”), which Master Note includes the terms and provisions for the Issuer’s Interest-Bearing Commercial Paper Notes that are set forth in this
Statement of Terms, since this Statement of Terms constitutes an integral part of the Underlying Records as defined and referred to in the Master Note. 

 (b) “Business Day” means any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized or required by law, executive order or regulation to be
closed in New York City and, with respect to LIBOR Notes (as defined below) is also a London Business Day. “London Business Day” means, a day, other than a Saturday or Sunday, on which dealings in deposits in U.S. dollars are transacted in
the London interbank market. 
  

	 	2.	Interest. (a) Each Note will bear interest at a fixed rate (a “Fixed Rate Note”) or at a floating rate (a “Floating Rate Note”).

 (b) The Supplement sent to each holder of such Note will describe the following terms: (i) whether such Note is a Fixed
Rate Note or a Floating Rate Note and whether such Note is an Original Issue Discount Note (as defined below); (ii) the date on which such Note will be issued (the “Issue Date”); (iii) the Stated Maturity Date (as defined below);
(iv) if such Note is a Fixed Rate Note, the rate per annum at which such Note will bear interest, if any, and the Interest Payment Dates; (v) if such Note is a Floating Rate Note, the Base Rate, the Index Maturity, the Interest Reset
Dates, the Interest Payment Dates and the Spread and/or Spread Multiplier, if any (all as defined below), and any other terms relating to the particular method of calculating the interest rate for such Note; and (vi) any other terms applicable
specifically to such Note. “Original Issue Discount Note” means a Note which has a stated redemption price at the Stated Maturity Date that exceeds its Issue Price by more than a specified de minimis amount and which the Supplement
indicates will be an “Original Issue Discount Note”. 
 (c) Each Fixed Rate Note will bear interest from its Issue Date at the rate
per annum specified in the Supplement until the principal amount thereof is paid or made available for payment. Interest on each Fixed Rate Note will be payable on the dates specified in the Supplement (each an “Interest Payment Date” for
a Fixed Rate Note) and on the Maturity Date (as defined below). Interest on Fixed Rate Notes will be computed on the basis of a 360-day year of twelve 30-day months. 
 If any Interest Payment Date or the Maturity Date of a Fixed Rate Note falls on a day that is not a Business Day, the required payment of principal, premium, if any, and/or interest will be payable on the next
succeeding Business Day, and no additional interest will accrue in respect of the payment made on that next succeeding Business Day. 
  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    22 

 (d) The interest rate on each Floating Rate Note for each Interest Reset Period (as defined below) will be determined by
reference to an interest rate basis (a “Base Rate”) plus or minus a number of basis points (one basis point equals one-hundredth of a percentage point) (the “Spread”), if any, and/or multiplied by a certain percentage (the
“Spread Multiplier”), if any, until the principal thereof is paid or made available for payment. The Supplement will designate which of the following Base Rates is applicable to the related Floating Rate Note: (a) the CD Rate (a
“CD Rate Note”), (b) the Commercial Paper Rate (a “Commercial Paper Rate Note”), (c) the Federal Funds Rate (a “Federal Funds Rate Note”), (d) LIBOR (a “LIBOR Note”), (e) the Prime Rate (a
“Prime Rate Note”), (f) the Treasury Rate (a “Treasury Rate Note”) or (g) such other Base Rate as may be specified in such Supplement. 
 The rate of interest on each Floating Rate Note will be reset daily, weekly, monthly, quarterly or semi-annually (the “Interest Reset Period”). The date or dates on which interest will be reset (each an
“Interest Reset Date”) will be, unless otherwise specified in the Supplement, in the case of Floating Rate Notes which reset daily, each Business Day, in the case of Floating Rate Notes (other than Treasury Rate Notes) that reset weekly,
the Wednesday of each week; in the case of Treasury Rate Notes that reset weekly, the Tuesday of each week; in the case of Floating Rate Notes that reset monthly, the third Wednesday of each month; in the case of Floating Rate Notes that reset
quarterly, the third Wednesday of March, June, September and December; and in the case of Floating Rate Notes that reset semiannually, the third Wednesday of the two months specified in the Supplement. If any Interest Reset Date for any Floating
Rate Note is not a Business Day, such Interest Reset Date will be postponed to the next day that is a Business Day, except that in the case of a LIBOR Note, if such Business Day is in the next succeeding calendar month, such Interest Reset Date
shall be the immediately preceding Business Day. Interest on each Floating Rate Note will be payable monthly, quarterly or semiannually (the “Interest Payment Period”) and on the Maturity Date. Unless otherwise specified in the Supplement,
and except as provided below, the date or dates on which interest will be payable (each an “Interest Payment Date” for a Floating Rate Note) will be, in the case of Floating Rate Notes with a monthly Interest Payment Period, on the third
Wednesday of each month; in the case of Floating Rate Notes with a quarterly Interest Payment Period, on the third Wednesday of March, June, September and December; and in the case of Floating Rate Notes with a semiannual Interest Payment Period, on
the third Wednesday of the two months specified in the Supplement. In addition, the Maturity Date will also be an Interest Payment Date. 
 If any Interest
Payment Date for any Floating Rate Note (other than an Interest Payment Date occurring on the Maturity Date) would otherwise be a day that is not a Business Day, such Interest Payment Date shall be postponed to the next day that is a Business Day,
except that in the case of a LIBOR Note, if such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. If the Maturity Date of a Floating Rate Note falls on a day that is
not a Business Day, the payment of principal and interest will be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after such maturity. 
 Interest payments on each Interest Payment Date for Floating Rate Notes will include accrued interest from and including the Issue Date or from and including the last
date in respect of which interest has been paid, as the case may be, to, but excluding, such Interest Payment Date. On the Maturity Date, the interest payable on a Floating Rate Note will include interest accrued to, but excluding, the Maturity
Date. Accrued interest will be calculated by multiplying the principal amount of a Floating Rate Note by an accrued interest factor. This accrued interest factor will be computed by adding the interest factors 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    23 

 
calculated for each day in the period for which accrued interest is being calculated. The interest factor (expressed as a decimal) for each such day will be
computed by dividing the interest rate applicable to such day by 360, in the cases where the Base Rate is the CD Rate, Commercial Paper Rate, Federal Funds Rate, LIBOR or Prime Rate, or by the actual number of days in the year, in the case where the
Base Rate is the Treasury Rate. The interest rate in effect on each day will be (i) if such day is an Interest Reset Date, the interest rate with respect to the Interest Determination Date (as defined below) pertaining to such Interest Reset
Date, or (ii) if such day is not an Interest Reset Date, the interest rate with respect to the Interest Determination Date pertaining to the next preceding Interest Reset Date, subject in either case to any adjustment by a Spread and/or a
Spread Multiplier. 
 The “Interest Determination Date” where the Base Rate is the CD Rate or the Commercial Paper Rate will be the second Business
Day next preceding an Interest Reset Date. The Interest Determination Date where the Base Rate is the Federal Funds Rate or the Prime Rate will be the Business Day next preceding an Interest Reset Date. The Interest Determination Date where the Base
Rate is LIBOR will be the second London Business Day next preceding an Interest Reset Date. The Interest Determination Date where the Base Rate is the Treasury Rate will be the day of the week in which such Interest Reset Date falls when Treasury
Bills are normally auctioned. Treasury Bills are normally sold at auction on Monday of each week, unless that day is a legal holiday, in which case the auction is held on the following Tuesday or the preceding Friday. If an auction is so held on the
preceding Friday, such Friday will be the Interest Determination Date pertaining to the Interest Reset Date occurring in the next succeeding week. 
 The
“Index Maturity” is the period to maturity of the instrument or obligation from which the applicable Base Rate is calculated. 
 The
“Calculation Date,” where applicable, shall be the earlier of (i) the tenth calendar day following the applicable Interest Determination Date or (ii) the Business Day preceding the applicable Interest Payment Date or Maturity
Date. 
 All times referred to herein reflect New York City time, unless otherwise specified. 
 The Issuer shall specify in writing to the Issuing and Paying Agent which party will be the calculation agent (the “Calculation Agent”) with respect to the Floating Rate Notes. The Calculation Agent will
provide the interest rate then in effect and, if determined, the interest rate which will become effective on the next Interest Reset Date with respect to such Floating Rate Note to the Issuing and Paying Agent as soon as the interest rate with
respect to such Floating Rate Note has been determined and as soon as practicable after any change in such interest rate. 
 All percentages resulting from
any calculation on Floating Rate Notes will be rounded to the nearest one hundred-thousandth of a percentage point, with five-one millionths of a percentage point rounded upwards. For example, 9.876545% (or .09876545) would be rounded to 9.87655%
(or .0987655). All dollar amounts used in or resulting from any calculation on Floating Rate Notes will be rounded, in the case of U.S. dollars, to the nearest cent or, in the case of a foreign currency, to the nearest unit (with one-half cent or
unit being rounded upwards). 
 CD Rate Notes 
 “CD Rate” means the rate on any Interest Determination Date for negotiable certificates of deposit having the Index Maturity as published by the Board of Governors of the Federal Reserve System (the “FRB”) in
“Statistical Release H.15(519), Selected Interest Rates” or any successor publication of the FRB (“H.15(519)”) under the heading “CDs (Secondary Market)”. 
  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    24 

 If the above rate is not published in H.15(519) by 3:00 p.m. on the Calculation Date, the CD Rate will be
the rate on such Interest Determination Date set forth in the daily update of H.15(519), available through the world wide website of the FRB at http://www.federalreserve.gov/releases/h15/Update, or any successor site or publication or other
recognized electronic source used for the purpose of displaying the applicable rate (“H.15 Daily Update”) under the caption “CDs (Secondary Market)”. 
 If such rate is not published in either H.15(519) or H.15 Daily Update by 3:00 p.m. on the Calculation Date, the Calculation Agent will determine the CD Rate to be the arithmetic mean of the secondary market offered
rates as of 10:00 a.m. on such Interest Determination Date of three leading nonbank dealers in negotiable U.S. dollar certificates of deposit in New York City selected by the Calculation Agent for negotiable U.S. dollar certificates of deposit of
major United States money center banks of the highest credit standing in the market for negotiable certificates of deposit with a remaining maturity closest to the Index Maturity in the denomination of $5,000,000. 
 If the dealers selected by the Calculation Agent are not quoting as set forth above, the CD Rate will remain the CD Rate then in effect on such Interest
Determination Date. 
 Commercial Paper Rate Notes 
 “Commercial Paper Rate” means the Money Market Yield (calculated as described below) of the rate on any Interest Determination Date for commercial paper having the Index Maturity, as published in H.15(519)
under the heading “Commercial Paper-Nonfinancial”. 
 If the above rate is not published in H.15(519) by 3:00 p.m. on the
Calculation Date, then the Commercial Paper Rate will be the Money Market Yield of the rate on such Interest Determination Date for commercial paper of the Index Maturity as published in H.15 Daily Update under the heading “Commercial
Paper-Nonfinancial”. 
 If by 3:00 p.m. on such Calculation Date such rate is not published in either H.15(519) or H.15 Daily Update,
then the Calculation Agent will determine the Commercial Paper Rate to be the Money Market Yield of the arithmetic mean of the offered rates as of 11:00 a.m. on such Interest Determination Date of three leading dealers of U.S. dollar commercial
paper in New York City selected by the Calculation Agent for commercial paper of the Index Maturity placed for an industrial issuer whose bond rating is “AA,” or the equivalent, from a nationally recognized statistical rating organization.

 If the dealers selected by the Calculation Agent are not quoting as mentioned above, the Commercial Paper Rate with respect to such
Interest Determination Date will remain the Commercial Paper Rate then in effect on such Interest Determination Date. 
 “Money Market
Yield” will be a yield calculated in accordance with the following formula: 
  

							
	 	 	 	 	D x 360	  	 
	Money Market Yield	 	=	 	  
	  	
		 		 	360 - (D x M)	  	
		 		 		  	

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    25 

 where “D” refers to the applicable per annum rate for commercial paper quoted on a bank
discount basis and expressed as a decimal and “M” refers to the actual number of days in the interest period for which interest is being calculated. 
 Federal Funds Rate Notes 
 “Federal Funds Rate” means the rate on any Interest Determination Date for federal funds
as published in H.15(519) under the heading “Federal Funds (Effective)” and displayed on Moneyline Telerate (or any successor service) on page 120 (or any other page as may replace the specified page on that service) (“Telerate Page
120”). 
 If the above rate does not appear on Telerate Page 120 or is not so published by 3:00 p.m. on the Calculation Date, the Federal
Funds Rate will be the rate on such Interest Determination Date as published in H.15 Daily Update under the heading “Federal Funds/(Effective)”. 
 If such rate is not published as described above by 3:00 p.m. on the Calculation Date, the Calculation Agent will determine the Federal Funds Rate to be the arithmetic mean of the rates for the last transaction in
overnight U.S. dollar federal funds arranged by each of three leading brokers of Federal Funds transactions in New York City selected by the Calculation Agent prior to 9:00 a.m. on such Interest Determination Date. 
 If the brokers selected by the Calculation Agent are not quoting as mentioned above, the Federal Funds Rate will remain the Federal Funds Rate then in
effect on such Interest Determination Date. 
 LIBOR Notes 
 The London Interbank offered rate (“LIBOR”) means, with respect to any Interest Determination Date, the rate for deposits in U.S. dollars having the Index Maturity that appears on the Designated LIBOR Page
as of 11:00 a.m., London time, on such Interest Determination Date. 
 If no rate appears, LIBOR will be determined on the basis of the rates
at approximately 11:00 a.m., London time, on such Interest Determination Date at which deposits in U.S. dollars are offered to prime banks in the London interbank market by four major banks in such market selected by the Calculation Agent for a term
equal to the Index Maturity and in principal amount equal to an amount that in the Calculation Agent’s judgment is representative for a single transaction in U.S. dollars in such market at such time (a “Representative Amount”). The
Calculation Agent will request the principal London office of each of such banks to provide a quotation of its rate. If at least two such quotations are provided, LIBOR will be the arithmetic mean of such quotations. If fewer than two quotations are
provided, LIBOR for such interest period will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in New York City, on such Interest Determination Date by three major banks in New York City, selected by the Calculation Agent, for
loans in U.S. dollars to leading European banks, for a term equal to the Index Maturity and in a Representative Amount; provided, however, that if fewer than three banks so selected by the Calculation Agent are providing such quotations, the then
existing LIBOR rate will remain in effect for such Interest Payment Period. 
 “Designated LIBOR Page” means the display designated
as page “3750” on Moneyline Telerate (or such other page as may replace the 3750 page on that service or such other service or services as may be nominated by the British Bankers’ Association for the purposes of displaying London
interbank offered rates for U.S. dollar deposits).

Program    n    26 

 Prime Rate Notes 
 “Prime Rate” means the rate on any Interest Determination Date as published in H.15(519) under the heading “Bank Prime Loan”. 
 If the above rate is not published in H.15(519) prior to 3:00 p.m. on the Calculation Date, then the Prime Rate will be the rate on such Interest
Determination Date as published in H.15 Daily Update opposite the caption “Bank Prime Loan”. 
 If the rate is not published prior
to 3:00 p.m. on the Calculation Date in either H.15(519) or H.15 Daily Update, then the Calculation Agent will determine the Prime Rate to be the arithmetic mean of the rates of interest publicly announced by each bank that appears on the Reuters
Screen US PRIME1 Page (as defined below) as such bank’s prime rate or base lending rate as of 11:00 a.m., on that Interest Determination Date. 
 If fewer than four such rates referred to above are so published by 3:00 p.m. on the Calculation Date, the Calculation Agent will determine the Prime Rate to be the arithmetic mean of the prime rates or base lending rates quoted on the
basis of the actual number of days in the year divided by 360 as of the close of business on such Interest Determination Date by three major banks in New York City selected by the Calculation Agent. 
 If the banks selected are not quoting as mentioned above, the Prime Rate will remain the Prime Rate in effect on such Interest Determination Date.

 “Reuters Screen US PRIME1 Page” means the display designated as page “US PRIME1” on the Reuters Monitor Money Rates

the Index Maturity specified in the Supplement, or 
 (7) if the dealers so selected by the Calculation Agent are not quoting as mentioned in
clause (6), the Treasury Rate in effect on the particular Interest Determination Date.

each obligation evidenced by such Note (together with interest accrued and unpaid thereon) shall become, without any notice or demand, immediately due and payable. 

  

	5.	Obligation Absolute. No provision of the Issuing and Paying Agency Agreement under which the Notes are issued shall alter or impair the obligation of the Issuer, which is

 Certain terms used in this Agreement are defined in Section 6

 The Addendum to this Agreement, and any Annexes or Exhibits described in this Agreement or such Addendum, are hereby incorporated into this
Agreement and made fully a part hereof.

and (ii) the Dealer has and shall have no obligation to purchase the Notes from the Issuer or to arrange any sale of the Notes for the account of the Issuer, the parties hereto agree that in any case where the Dealer purchases Notes from the
Issuer, or arranges for the sale of Notes by the Issuer, such Notes will be purchased or sold by the Dealer in reliance on the representations, warranties, covenants and agreements of the Issuer contained herein or made pursuant hereto and on the
terms and conditions and in the manner provided herein. 

  

	 	1.2	So long as this Agreement shall remain in effect, and in addition to the limitations contained in Section 1.7 hereof, the Issuer shall not, without the consent of the Dealer,
offer, solicit or accept offers to purchase, or sell, any Notes except (a) in transactions with one or more dealers which may from time to time after the date hereof become dealers with respect to the Notes by executing with the Issuer one or
more agreements which contain provisions substantially identical to those contained in Section 1 of this Agreement, of which the Issuer hereby undertakes to provide the Dealer prompt notice or (b) in transactions with the other dealers

offers to purchase, or sell, any Notes directly on its own behalf in transactions with persons other than broker-dealers as specifically permitted in this Section 1.2. 

  

	 	1.3	The Notes shall be in a minimum denomination of $250,000 or integral multiples of $1,000 in excess thereof, will bear such interest rates, if interest bearing, or will be sold at
such discount from their face amounts, as shall be agreed upon by the Dealer and the Issuer, shall have a maturity not exceeding 397 days from the date of issuance and may have such terms as are specified in Exhibit C hereto or the Private Placement

Program    n    2 

	 	1.5	If the Issuer and the Dealer shall agree on the terms of the purchase of any Note by the Dealer or the sale of any Note arranged by the Dealer (including, but not limited to,
agreement with respect to the date of issue, purchase price, principal amount, maturity and interest rate or interest rate index and margin (in the case of interest-bearing Notes) or discount thereof (in the case of Notes issued on a discount
basis), and appropriate compensation for the Dealer’s services hereunder) pursuant to this Agreement, the Issuer shall cause such Note to be issued and delivered in accordance with the terms of the Issuing and Paying Agency Agreement and
payment for such Note shall be made by the purchaser thereof, either directly or through the Dealer, to the Issuing and Paying Agent, for the account of the Issuer. Except as otherwise agreed, in the event that the Dealer is acting as an agent of
the Issuer and a purchaser shall either fail to accept delivery of or make payment for a Note on the date fixed for settlement, the Dealer shall promptly notify the Issuer, and if the Dealer has theretofore paid the Issuer for the Note, the Issuer
will promptly return such funds to the Dealer against its return of the Note to the Issuer, in the case of a certificated Note, and upon notice of such failure in the case of a book-entry Note. If such failure occurred for any reason other than
default by the Dealer, the Issuer shall reimburse the Dealer on an equitable basis for the Dealer’s loss of the use of such funds for the period such funds were credited to the Issuer’s account. 

  

	 	1.6	The Dealer and the Issuer hereby establish and agree to observe the following procedures in connection with offers, sales and subsequent resales or other transfers of the Notes:

  

	 	(a)	Offers and sales of the Notes by or through the Dealer shall be made by the Dealer only to: (i) investors reasonably believed by the Dealer to be Qualified Institutional Buyers

	 	(b)	Resales and other transfers of the Notes by the holders thereof shall be made only in accordance with the restrictions in the legend described in clause (e) below.

  

	 	(c)	No general solicitation or general advertising shall be used in connection with the offering of the Notes. Without limiting the generality of the foregoing, the Issuer shall not
issue any press release or place or publish any “tombstone” or other advertisement relating to the Notes without promptly providing notice to the Dealer. The Dealer shall not issue any press release or publish any “tombstone” or
other advertisement relating to the Notes without the prior written consent of the Issuer. 

  

	 	(d)	No sale of Notes to any one purchaser shall be for less than $250,000 principal or face amount, and no Note shall be issued in a smaller principal or face amount. If the purchaser
is a non-bank fiduciary acting on behalf of others, each person for whom such purchaser is acting must purchase at least $250,000 principal or face amount of Notes. 

  

	 	(e)	 Offers and sales of the Notes by the Issuer through the Dealer acting as agent for the Issuer shall be made in accordance with Rule 506 under the Securities Act,
and shall be subject to the restrictions described in the legend appearing on Exhibit A hereto. A legend substantially to the effect of such Exhibit A shall appear as part of the Private Placement

Memorandum used in connection with offers and sales of Notes hereunder, as well as on each individual certificate representing a Note and each Master Note
representing book-entry Notes offered and sold pursuant to this Agreement. 

  

	 	(f)	The Dealer shall furnish or shall have furnished to each purchaser of Notes for which it has acted as the Dealer a copy of the then-current Private Placement Memorandum unless such
purchaser has previously received a copy of the Private Placement Memorandum as then in effect. The Private Placement Memorandum shall expressly state that any person to whom Notes are offered shall have an opportunity to ask questions of, and
receive information from, the Issuer and the Dealer and shall provide the names, addresses and telephone numbers of the persons from whom information regarding the Issuer may be obtained. 

  

	 	(g)	The Issuer agrees, for the benefit of the Dealer and each of the holders and prospective purchasers from time to time of the Notes that, if at any time the Issuer shall not be
subject to Section 13 or 15(d) of the Exchange Act, the Issuer will furnish, upon request and at its expense, to the Dealer and to holders and prospective purchasers of Notes information required by Rule 144A(d)(4)(i) in compliance with Rule
144A(d). 

  

	 	(h)	In the event that any Note offered or to be offered by the Dealer would be ineligible for resale under Rule 144A, the Issuer shall immediately notify the Dealer (by telephone,
confirmed in writing) of such fact and shall promptly prepare and deliver to the Dealer an amendment or supplement to the Private Placement Memorandum describing the Notes that are ineligible, the reason for such ineligibility and any other relevant
information relating thereto. 

  

	 	(i)	Dealer hereby agrees with the Issuer not to offer or sell any Notes in a manner that might call into question the availability of the private offering exemption contained in
Section 4(2) of the Securities Act and Rule 144A thereunder. 

  

	 	1.7	The Issuer hereby represents and warrants to the Dealer, in connection with offers, sales and resales of Notes, as follows: 

  

	 	(a)	 The Issuer hereby confirms to the Dealer that within the preceding six months, neither the Issuer nor any person other than the Dealer or the other dealers referred
to in Section 1.2 hereof acting on behalf of the Issuer has offered or sold any Notes, or any substantially similar security of the Issuer (including, without limitation, medium-term notes issued by the Issuer), to, or solicited offers to buy
any such security from, any person other than the Dealer or the other dealers referred to in Section 1.2 hereof. The Issuer also agrees that (except as permitted by Section 1.6(i)), as long as the Notes are being offered for sale by the
Dealer and the other dealers referred to in Section 1.2 hereof as contemplated hereby and until at least six months after the offer of Notes hereunder has been terminated, neither the Issuer nor any person other than the Dealer or the other
dealers referred to in Section 1.2 hereof (except as contemplated by Section 1.2 hereof) will offer the Notes or any substantially similar security of the Issuer for sale to, or solicit offers to buy any such security from, any person
other than the Dealer or the other dealers referred to in Section 1.2 hereof, it being understood that such agreement is made with a view to bringing the offer and sale of the Notes within the exemption provided by Section 4(2) of the
Securities Act and Rule 506 thereunder and shall survive any termination of this Agreement. The Issuer hereby represents and warrants that it 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    4 

	 	 
has not taken or omitted to take, and will not take or omit to take, any action that would cause the offering and sale of Notes hereunder to be integrated
with any other offering of securities, whether such offering is made by the Issuer or some other party or parties. 

  

	 	(b)	Except with previous notification to the Dealer, the Issuer represents and agrees that the proceeds of the sale of the Notes are not currently contemplated to be used for the
purpose of buying, carrying or trading securities within the meaning of Regulation T and the interpretations thereunder by the Board of Governors of the Federal Reserve System. The Issuer will use the net proceeds from the sale of the Notes to fund
the tender offer for certain shares of the Issuer’s common stock, fees and expenses relating to the tender offer and to the Issuer’s merger with CBOT Holdings Inc. and for other general corporation purposes. Except as set forth in the
preceding sentence, in the event that the Issuer determines to use such proceeds for the purpose of buying, carrying or trading securities, whether in connection with an acquisition of another company or otherwise, the Issuer shall give the Dealer
at least five business days’ prior written notice to that effect. The Issuer shall also give the Dealer prompt notice of the actual date that it commences to purchase such securities with the proceeds of the Notes. Thereafter, in the event that
the Dealer purchases Notes as principal and does not resell such Notes on the day of such purchase, to the extent necessary to comply with Regulation T and the interpretations thereunder, the Dealer will sell such Notes either (i) only to
offerees it reasonably believes to be Qualified Institutional Buyers or to Qualified Institutional Buyers it reasonably believes are acting for other Qualified Institutional Buyers, in each case in accordance with Rule 144A or (ii) in a manner
which would not cause a violation of Regulation T and the interpretations thereunder. 

  

	 	1.8	The Dealer hereby agrees with the Issuer that the Dealer will not offer or sell any Notes in a manner that contradicts, in any material respect, the Issuer Information.

  

	2.	Representations and Warranties of Issuer. 

 The
Issuer represents and warrants that each acceptance by the Issuer of an offer for the purchase of Notes shall be deemed an affirmation by the Issuer that its representations and warranties set forth in this Article 2 are true and correct at the time
of such acceptance: 
  

	 	2.1	The Issuer is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all the requisite power and
authority to execute, deliver and perform its obligations under the Notes, this Agreement and the Issuing and Paying Agency Agreement. 

  

	 	2.2	This Agreement and the Issuing and Paying Agency Agreement have been duly authorized, executed and delivered by the Issuer and constitute legal, valid and binding obligations of the
Issuer enforceable against the Issuer in accordance with their terms, subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general principles of equity
(regardless of whether enforcement is sought in a proceeding in equity or at law). 

  

	 	2.3	 The Notes have been duly authorized, and when issued as provided in the Issuing and Paying Agency Agreement, will be duly and validly issued and will constitute
legal, valid and binding obligations of the Issuer enforceable against the Issuer in accordance with their terms, subject

Program    n    5 

	 	 
to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally, and subject, as to enforceability, to general principles of
equity (regardless of whether enforcement is sought in a proceeding in equity or at law). 

  

	 	2.4	The offer and sale of the Notes in the manner contemplated hereby do not require registration of the Notes under the Securities Act, pursuant to the exemption from registration
contained in Section 4(2) thereof, and no indenture in respect of the Notes is required to be qualified under the Trust Indenture Act of 1939, as amended. 

  

	 	2.5	The Notes will rank at least pari passu with all other unsecured and unsubordinated indebtedness of the Issuer. 

  

	 	2.6	No consent or action of, or filing or registration with, any governmental or public regulatory body or authority, including the SEC, is required to authorize, or is otherwise
required in connection with the execution, delivery or performance of, this Agreement, the Notes or the Issuing and Paying Agency Agreement, except as may be required by the securities or Blue Sky laws of the various states in connection with the
offer and sale of the Notes. 

  

	 	2.7	Neither the execution and delivery of this Agreement and the Issuing and Paying Agency Agreement, nor the issuance of the Notes in accordance with the Issuing and Paying Agency
Agreement, nor the fulfillment of or compliance with the terms and provisions hereof or thereof by the Issuer, will (i) result in the creation or imposition of any mortgage, lien, charge or encumbrance of any nature whatsoever upon any of the
properties or assets of the Issuer, or (ii) violate or result in a breach or a default under any of the terms of the Issuer’s charter documents or by-laws, any contract or instrument to which the Issuer is a party or by which it or its
property is bound, or any law or regulation, or any order, writ, injunction or decree of any court or government instrumentality, to which the Issuer is subject or by which it or its property is bound, which breach or default might have a material
adverse effect on the ability of the Issuer to perform its obligations under this Agreement, the Notes or the Issuing and Paying Agency Agreement. 

  

	 	2.8	There is no litigation or governmental proceeding pending, or to the knowledge of the Issuer threatened, against or affecting the Issuer or any of its subsidiaries which might
result in a material adverse change in the ability of the Issuer to perform its obligations under this Agreement, the Notes or the Issuing and Paying Agency Agreement. 

  

	 	2.9	The Issuer is not an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

and warranty by the Issuer to the Dealer, as of the date thereof, that, both before and after giving effect to such issuance and after giving effect to such amendment or supplement, (i) the representations and warranties 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    6 

	 	 
given by the Issuer set forth in this Section 2 remain true and correct on and as of such date as if made on and as of such date, (ii) in the case
of an issuance of Notes, the Notes being issued on such date have been duly and validly issued and constitute legal, valid and binding obligations of the Issuer, enforceable against the Issuer in accordance with their terms, subject to applicable
bankruptcy, insolvency and similar laws affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law), (iii) in
the case of an issuance of Notes, since the date of the most recent Private Placement Memorandum, there has been no material adverse change in the condition (financial or otherwise) or operations of the Issuer which has not been disclosed to the

	 	3.2	The Issuer shall, whenever there shall occur any change in the Issuer’s condition (financial or otherwise) or operations or any development or occurrence in relation to the
Issuer that would have a material adverse effect on the holders of the Notes or on potential holders of the Notes, promptly, and in any event prior to any subsequent issuance of Notes hereunder, notify the Dealer (by telephone, confirmed in writing)
of such change, development or occurrence. 

  

	 	3.3	The Issuer shall from time to time furnish to the Dealer such public information as the Dealer may reasonably request regarding (i) the Issuer’s operations and financial
condition, (ii) the due authorization and execution of the Notes and (iii) the Issuer’s ability to pay the Notes as they mature. 

  

	 	3.4	The Issuer will take all such action as the Dealer may reasonably request to ensure that each offer and each sale of the Notes will comply with any applicable state Blue Sky laws;
provided, however, that the Issuer shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation in any jurisdiction in which it is not so qualified or subject itself to taxation in respect of doing
business in any jurisdiction in which it is not otherwise so subject. 

  

	 	3.5	The Issuer will not be in default of any of its obligations hereunder, under the Notes or under the Issuing and Paying Agency Agreement, at any time that any of the Notes are
outstanding. 

  

	 	3.6	 The Issuer shall not issue Notes hereunder until the Dealer shall have received (a) an opinion of counsel to the Issuer, addressed to the Dealer, reasonably
satisfactory in form and substance to the Dealer, (b) a copy of the executed Issuing and Paying Agency Agreement as then in effect, (c) a copy of resolutions adopted by the Board of Directors of the Issuer, reasonably satisfactory in form

Dealer’s counsel. 

  

	4.	Disclosure. 

  

	 	4.1	The Private Placement Memorandum and its contents (other than the Dealer Information) shall be the sole responsibility of the Issuer. The Private Placement Memorandum shall contain

acquire without unreasonable effort or expense.

	 	4.3	(a) The Issuer further agrees to notify the Dealer promptly upon the occurrence of any event relating to or affecting the Issuer that would cause the Issuer Information then in
existence to include an untrue statement of a material fact or to omit to state a material fact necessary in order to make the statements contained therein, in light of the circumstances under which they are made, not misleading. The Dealer agrees
that, upon such notification, all solicitations and sales of Notes shall be suspended. 

 (b) In the event that the Issuer gives
the Dealer notice pursuant to Section 4.3(a) and the Dealer notifies the Issuer that it then has Notes it is holding in inventory, the Issuer agrees promptly to supplement or amend the Private Placement Memorandum so that the Private Placement
Memorandum, as amended or supplemented, shall not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not
misleading, and the Issuer shall make such supplement or amendment available to the Dealer. 
 (c) In the event that (i) the Issuer gives
the Dealer notice pursuant to Section 4.3(a), (ii) the Dealer does not notify the Issuer that it is then holding Notes in inventory and (iii) the Issuer chooses not to promptly amend or supplement the Private Placement Memorandum in
the manner described in clause (b) above, then all solicitations and sales of Notes shall be suspended until such time as the Issuer has so amended or supplemented the Private Placement Memorandum, and made such amendment or supplement
available to the Dealer. 
  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    8 

 (d) Without limiting the generality of Section 4.3(a), the Issuer shall review, amend and supplement

Memorandum is accurate and complete.

penalties, suits, causes of action, losses, damages, claims, costs and expenses (including, without limitation, reasonable fees and disbursements of counsel) or judgments of whatever kind or nature (each a “Claim”), imposed upon, incurred
by or asserted against the Merrill Lynch Indemnitees arising out of or based upon (i) any allegation that the Private Placement Memorandum, the Issuer Information or any other written information provided by the Issuer to the Dealer included

not misleading or (ii) arising out of or based upon the breach by the Issuer of any agreement, covenant or representation made in or pursuant to this Agreement which has a material adverse effect on the Dealer or on the holders of the Notes;
provided that this indemnification shall not apply to the extent that the Claim arises out of or is based upon Dealer Information. For the avoidance of doubt, it is agreed that Dealer Information consists of the logo of the Dealer and the contact
information to obtain additional information, in each case as provided in the Private Placement Memorandum. Notwithstanding the foregoing, it is agreed that the obligations of the Issuer under this Section 5 shall not extend to the

hand, sought to be charged with any liability shall contribute to the aggregate costs in connection with any Claim in the proportion of their respective economic 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    9 

	 	 
interests; provided, however, that such contribution by the Issuer shall be in an amount such that the aggregate costs incurred by the Dealer do not exceed
the aggregate of the commissions and fees earned by the Dealer hereunder with respect to the issue or issues of Notes to which such Claim relates. For purposes of this Section 5, “economic interests” of the Issuer Indemnitees shall be
equal to the aggregate proceeds of the Notes issued in connection with this Agreement received by the Issuer and “economic interests” of any Merrill Lynch Indemnitees shall be equal to the aggregate commissions and fees earned by the
Dealer hereunder.

 Model Opinion of Counsel to Issuer 
 [Company Letterhead] 
 August 16, 2007 
 To the Addressees listed on 
 Schedule I hereto 
 Ladies and Gentlemen: 
 I am the General Counsel of CME Group
Inc., a Delaware corporation (the “Company”), and, as such, I am furnishing this opinion in connection with each of (i) that certain Commercial Paper Dealer Agreement, dated as of August 16, 2007 (the “Lehman
Dealer Agreement”), between the Company, as issuer, and Lehman Brothers Inc., as dealer (the “Lehman Dealer”), (ii) that certain Commercial Paper Dealer Agreement, dated as of August 16, 2007 (the “Merrill
Dealer Agreement” and, together with the Lehman Dealer Agreement, collectively, the “Dealer Agreements”), among the Company, as issuer, and Merrill Lynch Money Markets Inc., as dealer for Notes (as defined in the Merrill
Dealer Agreement) with maturities up to 270 days (“MLMM”), and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as dealer for Notes (as defined in the Merrill Dealer Agreement) with maturities over 270 days
(“MLPF&S” and, together with MLMM, collectively, the “Merrill Dealer”), (iii) that certain Issuing and Paying Agency Agreement, dated as of August 16, 2007 (the “Issuing and Paying Agency
Agreement”), between the Company and JPMorgan Chase Bank, National Association, as issuing and paying agent (the “Issuing and Paying Agent”), and (iv) the Master Note dated August 16, 2007 (the “Master
Note”). The Lehman Dealer Agreement, the Merrill Dealer Agreement, the Issuing and Paying Agency Agreement and the Master Note shall hereafter be referred to collectively as the “Transaction Agreements.” This opinion is
being delivered pursuant to Section 3.6 of each Dealer Agreement. 
 In my examination, I have assumed the genuineness of all
signatures, including endorsements, the legal capacity and competency of natural persons, the authenticity of all documents submitted to me as originals, the conformity to original documents of all documents submitted to us as facsimile, electronic,
certified or photostatic copies, and the authenticity of the originals of such copies. When relevant facts were not independently established, I have relied upon statements of governmental officials and upon representations made in or pursuant to
the Transaction Agreements, certificates of appropriate representatives of the Company. 
 In rendering the opinions set forth herein, I have
examined and relied upon originals or copies of the Transaction Agreements and such other documents as I have deemed necessary or appropriate as a basis for the opinions set forth below. 
 Capitalized terms used herein and not otherwise defined herein shall have the same meanings herein as ascribed thereto in the Dealer Agreements. As used
herein, “Applicable Laws” means those laws, rules and regulations which, in my experience, are normally applicable to transactions of the type 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    15 

 
contemplated by the Transaction Agreements, without my having made any special investigation as to the applicability of any specific law, rule or regulation,
and which are not the subject of a specific opinion herein referring expressly to a particular law or laws. 
 I am a member of the Bar of
the State of Illinois and the foregoing opinions are limited to matters involving the Federal laws of the United States of America and the General Corporation Law of the State of Delaware and I do not express any opinion as to any other laws. I note
that the Transaction Agreements purport to be governed by the laws of the State of New York and I express no opinion with respect to the laws of the State of New York. 
 Based upon the foregoing and subject to the limitations, qualifications, exceptions and assumptions set forth herein, I am of the opinion that: 
 1. The Company is a corporation validly existing and in good standing under the laws of the State of Delaware. 
 2. The Company has all the requisite corporate power and authority to execute, deliver and perform its obligations under each of the Transaction
Agreements. The execution and delivery of each of the Transaction Agreements and the consummation by the Company of the transactions contemplated thereby have been duly authorized by all requisite corporate action on the part of the Company. Each of
each Dealer Agreement and the Issuing and Paying Agency Agreement has been duly executed and delivered by the Company. 
 3. In the event
that an Illinois court were to apply the substantive laws of the State of Illinois, notwithstanding the choice of law of the parties set forth in the Transaction Agreements, and without regard to choice of law principles, each of the Transaction
Agreements constitutes and, in the case of the Notes, when issued in accordance with the Issuing and Paying Agency Agreement and paid for by the purchasers thereof, will constitute, the valid and binding obligations of the Company, enforceable
against the Company in accordance with their terms under the Applicable Laws of the State of Illinois. 
 4. The execution and delivery by
the Company of each of the Transaction Agreements and the performance by the Company of its obligations under each of the Transaction Agreements, each in accordance with its terms, do not (i) conflict with the certificate of incorporation or
by-laws of the Company, (ii) constitute a violation of, or a default under any material agreements or instruments known to me (after due inquiry) to which the Company is a party or by which it is bound or to which it is subject or result in the
creation or imposition of any lien upon any property of the Company pursuant to the terms of any such material agreement or instrument or (iii) violate any order, writ, injunction or decree known to me (after due inquiry) of any court or
governmental authority or agency applicable to the Company. 
 5. The offer, sale and delivery of the Notes in the manner contemplated by the
Dealer Agreements do not require registration under the Securities Act of 1933, as amended, or qualification of any indenture under the Trust Indenture Act of 1939, as amended (it being understood that I express no opinion as to any subsequent
resale of any Note); and the Notes will rank at least pari passu with all other unsecured and unsubordinated indebtedness of the Company. 
 6. No consent, approval or authorization of, or filing, recording or registration with, any governmental authority, which has not been obtained or taken and is not in full force and effect, is required to authorize, or is required in
connection with, the execution or delivery of any of the 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    16 

 
Transaction Agreements by the Company or the enforceability of any of the Transaction Agreements against the Company, except as may be required by the
securities or Blue Sky laws of the various states in connection with the offer and sale of the Notes. 
 7. To the best of my knowledge,
except as disclosed in the Company’s public filings with the Securities and Exchange Commission, there is no litigation or governmental proceeding pending or threatened against the Company or any of its subsidiaries which would have a material
adverse effect on the ability of the Company to perform its obligations under the Transaction Agreements. 
 8. The Company is not an
“investment company” within the meaning of the Investment Company Act of 1940, as amended. 
 My opinions are subject to the
following assumptions and qualifications: 
 (a) enforcement may be limited by applicable bankruptcy, insolvency, reorganization, moratorium
or other similar laws affecting creditors’ rights generally and by general principles of equity (regardless of whether enforcement is sought in equity or at law); 
 (b) I have assumed that each of the Transaction Agreements constitutes the valid and binding obligation of each party to such Transaction Agreement (other than the Company to the extent expressly set forth herein)
enforceable against such other party in accordance with its terms; 
 (c) I express no opinion as to the effect on the opinions expressed
herein of (i) the compliance or non-compliance of any party (other than the Company to the extent expressly set forth herein) to the Transaction Agreements with any state, federal or other laws or regulations applicable to any of them or
(ii) the legal or regulatory status or the nature of the business of any party (other than the Company to the extent expressly set forth herein); 
 (d) I express no opinion as to the enforceability of any rights to contribution or indemnification provided for in the Transaction Agreements which are violative of the public policy underlying any law, rule or
regulation (including any federal or state securities law, rule or regulation); 
 (e) I express no opinion as to the applicability or effect
of any fraudulent transfer, preference or similar law on the Transaction Agreements or any transactions contemplated thereby; 
 (f) I
express no opinion on the enforceability of any provision in a Transaction Agreement purporting to prohibit, restrict or condition the assignment of rights under such Transaction Agreement to the extent such restriction on assignability is governed
by the Uniform Commercial Code; 
 (g) I express no opinion as to the enforceability of any provision of any Transaction Agreement to the
extent it purports to waive any objection a person may have that a suit, action or proceeding has been brought in an inconvenient forum or a forum lacking subject matter jurisdiction; 
 (h) for purposes of my opinion set forth in paragraph 5 above, I have assumed (a) the accuracy of the representations and warranties and compliance
with the agreements made by the Dealer in the Dealer Agreements (b) compliance by the Dealer with the offering and transfer procedures and restrictions required by the Dealer Agreements including, without limitation, the delivery to each
purchaser of the Notes of an offering memorandum containing a legend restricting offers, sales and resales of the Notes in the form required by the Dealer Agreements and (c) the accuracy of the representations and warranties made in accordance
with such offering memorandum by the initial purchasers of the Notes; and 
  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    17 

 (i) I express no opinion as to the enforceability of Section 7.3(a) of either Dealer Agreement.

 At the request of the Company, this opinion letter is, pursuant to Section 3.6 of each Dealer Agreement, provided to you by me in my
capacity as in-house counsel of the Company and may not be relied upon by any person for any purpose other than in connection with the transactions contemplated by the Transaction Agreements without, in each instance, my prior written consent. No
opinion is implied or is to be inferred beyond the opinions expressly stated above. I assume no obligation to update this letter for events, changes in law or circumstances occurring after the date of this opinion. 
 Very truly yours,

 Further
Provisions Relating to Indemnification 
  

	(a)	The Issuer agrees to reimburse each Merrill Lynch Indemnitee for all reasonable expenses (including reasonable fees and disbursements of external counsel) as they are incurred by it
in connection with investigating or defending any loss, claim, damage, liability or action in respect of which indemnification may be sought under Section 5.1 of the Agreement (whether or not it is a party to any such proceedings).

  

	(b)	Promptly after receipt by a Merrill Lynch Indemnitee of notice of the existence of a Claim arising under Section 5.1 of the Agreement, such Merrill Lynch Indemnitee will, if a
claim in respect thereof is to be made against the Issuer, notify the Issuer in writing of the existence thereof; provided that (i) the omission so to notify the Issuer will not relieve the Issuer from any liability which it may have hereunder
unless and except to the extent it did not otherwise learn of such Claim and such failure results in the forfeiture by the Issuer of substantial rights and defenses, and (ii) the omission so to notify the Issuer will not relieve it from
liability which it may have to a Merrill Lynch Indemnitee otherwise than on account of this indemnity agreement. In case any such Claim is made against any Merrill Lynch Indemnitee and it notifies the Issuer of the existence thereof, the Issuer will
be entitled to participate therein, and to the extent that it may elect by written notice delivered to the Merrill Lynch Indemnitee, to assume the defense thereof, with counsel reasonably satisfactory to such Merrill Lynch Indemnitee; provided that
if the defendants in any such Claim include both the Merrill Lynch Indemnitee and the Issuer, and the Merrill Lynch Indemnitee shall have concluded that there may be legal defenses available to it which are different from or additional to those
available to the Issuer, the Issuer shall not have the right to direct the defense of such Claim on behalf of such Merrill Lynch Indemnitee, and the Merrill Lynch Indemnitee shall have the right to select separate counsel to assert such legal
defenses on behalf of such Merrill Lynch Indemnitee. Upon receipt of notice from the Issuer to such Merrill Lynch Indemnitee of the Issuer’s election so to assume the defense of such Claim and approval by the Merrill Lynch Indemnitee of
counsel, the Issuer will not be liable to such Merrill Lynch Indemnitee for expenses incurred thereafter by the Merrill Lynch Indemnitee in connection with the defense thereof (other than reasonable costs of investigation) unless (i) the
Merrill Lynch Indemnitee shall have employed separate counsel in connection with the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the Issuer shall not be liable for the
expenses of more than one separate counsel (in addition to any local counsel in the jurisdiction in which any Claim is brought), approved by the Dealer, representing the Merrill Lynch Indemnitee who is party to such Claim), (ii) the Issuer
shall not have employed counsel reasonably satisfactory to the Merrill Lynch Indemnitee to represent the Merrill Lynch Indemnitee within a reasonable time after notice of existence of the Claim or (iii) the Issuer has authorized in writing the
employment of counsel for the Merrill Lynch Indemnitee. The indemnity, reimbursement and contribution obligations of the Issuer hereunder shall be in addition to any other liability the Issuer may otherwise have to a Merrill Lynch Indemnitee and
shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Issuer and any Indemnitee. The Issuer agrees that without the Dealer’s prior written consent, it will not settle, compromise or
consent to the entry of any judgment in any Claim in respect of which indemnification may be sought under the indemnification provision of the Agreement (whether or not the Dealer or any other Indemnitee is an actual or potential party to such
Claim), unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnitee from all liability arising out of such Claim and (ii) does not include a statement as to or an admission of fault, culpability
or failure to act, by or on behalf of any Indemnitee.

	(c)	The Dealer agrees to reimburse each Issuer Indemnitee for all reasonable expenses (including reasonable fees and disbursements of external counsel) as they are incurred by it in
connection with investigating or defending any loss, claim, damage, liability or action in respect of which indemnification may be sought under Section 5.2 of the Agreement (whether or not it is a party to any such proceedings).

  

	(d)	Promptly after receipt by an Issuer Indemnitee of notice of the existence of a Claim arising under Section 5.2 of the Agreement, such Issuer Indemnitee will, if a claim in
respect thereof is to be made against the Dealer, notify the Dealer in writing of the existence thereof; provided that (i) the omission so to notify the Dealer will not relieve the Dealer from any liability which it may have hereunder unless
and except to the extent it did not otherwise learn of such Claim and such failure results in the forfeiture by the Dealer of any of its rights and defenses that it reasonably deems to be material, and (ii) the omission so to notify the Dealer
will not relieve it from liability which it may have to an Issuer Indemnitee otherwise than on account of this indemnity agreement. In case any such Claim is made against any Issuer Indemnitee and it notifies the Dealer of the existence thereof, the
Dealer will be entitled to participate therein, and to the extent that it may elect by written notice delivered to the Issuer Indemnitee, to assume the defense thereof, with counsel reasonably satisfactory to such Issuer Indemnitee; provided that if
the defendants in any such Claim include both the Issuer Indemnitee and the Dealer, and the Issuer Indemnitee shall have concluded that there may be legal defenses available to it which are different from or additional to those available to the
Dealer, the Dealer shall not have the right to direct the defense of such Claim on behalf of such Issuer Indemnitee, and the Issuer Indemnitee shall have the right to select separate counsel to assert such legal defenses on behalf of such Issuer
Indemnitee. Upon receipt of notice from the Dealer to such Issuer Indemnitee of the Dealer’s election so to assume the defense of such Claim and approval by the Issuer Indemnitee of counsel, the Dealer will not be liable to such Issuer
Indemnitee for expenses incurred thereafter by the Issuer Indemnitee in connection with the defense thereof (other than reasonable costs of investigation) unless (i) the Issuer Indemnitee shall have employed separate counsel in connection with
the assertion of legal defenses in accordance with the proviso to the next preceding sentence (it being understood, however, that the Dealer shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel in
the jurisdiction in which any Claim is brought), approved by the Issuer, representing the Issuer Indemnitee who is party to such Claim), (ii) the Dealer shall not have employed counsel reasonably satisfactory to the Issuer Indemnitee to
represent the Issuer Indemnitee within a reasonable time after notice of existence of the Claim or (iii) the Dealer has authorized in writing the employment of counsel for the Issuer Indemnitee. The indemnity, reimbursement and contribution
obligations of the Dealer hereunder shall be in addition to any other liability the Dealer may otherwise have to an Issuer Indemnitee and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives
of the Dealer and any Issuer Indemnitee. The Dealer agrees that without the Issuer’s prior written consent, it will not settle, compromise or consent to the entry of any judgment in any Claim in respect of which indemnification may be sought
under the indemnification provision of the Agreement (whether or not the Issuer or any other Indemnitee is an actual or potential party to such Claim), unless such settlement, compromise or consent (i) includes an unconditional release of each
Indemnitee from all liability arising out of such Claim and (ii) does not include a statement as to or an admission of fault, culpability or failure to act, by or on behalf of any Indemnitee.

 Exhibit C 
 Statement of Terms for Interest – Bearing Commercial Paper Notes of CME Group Inc. 
 THE PROVISIONS SET FORTH BELOW ARE QUALIFIED TO
THE EXTENT APPLICABLE BY THE TRANSACTION SPECIFIC [PRICING] [PRIVATE PLACEMENT MEMORANDUM] SUPPLEMENT (THE “SUPPLEMENT”) (IF ANY) SENT TO EACH PURCHASER AT THE TIME OF THE TRANSACTION. 
  

	 	1.	General. (a) The obligations of the Issuer to which these terms apply (each a “Note”) are represented by one or more Master Notes (each, a “Master
Note”) issued in the name of (or of a nominee for) The Depository Trust Company (“DTC”), which Master Note includes the terms and provisions for the Issuer’s Interest-Bearing Commercial Paper Notes that are set forth in this
Statement of Terms, since this Statement of Terms constitutes an integral part of the Underlying Records as defined and referred to in the Master Note. 

 (b) “Business Day” means any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized or required by law, executive order or regulation to be
closed in New York City and, with respect to LIBOR Notes (as defined below) is also a London Business Day. “London Business Day” means, a day, other than a Saturday or Sunday, on which dealings in deposits in U.S. dollars are transacted in
the London interbank market. 
  

	 	2.	Interest. (a) Each Note will bear interest at a fixed rate (a “Fixed Rate Note”) or at a floating rate (a “Floating Rate Note”).

 (b) The Supplement sent to each holder of such Note will describe the following terms: (i) whether such Note is a Fixed
Rate Note or a Floating Rate Note and whether such Note is an Original Issue Discount Note (as defined below); (ii) the date on which such Note will be issued (the “Issue Date”); (iii) the Stated Maturity Date (as defined below);
(iv) if such Note is a Fixed Rate Note, the rate per annum at which such Note will bear interest, if any, and the Interest Payment Dates; (v) if such Note is a Floating Rate Note, the Base Rate, the Index Maturity, the Interest Reset
Dates, the Interest Payment Dates and the Spread and/or Spread Multiplier, if any (all as defined below), and any other terms relating to the particular method of calculating the interest rate for such Note; and (vi) any other terms applicable
specifically to such Note. “Original Issue Discount Note” means a Note which has a stated redemption price at the Stated Maturity Date that exceeds its Issue Price by more than a specified de minimis amount and which the Supplement
indicates will be an “Original Issue Discount Note”. 
 (c) Each Fixed Rate Note will bear interest from its Issue Date at the rate
per annum specified in the Supplement until the principal amount thereof is paid or made available for payment. Interest on each Fixed Rate Note will be payable on the dates specified in the Supplement (each an “Interest Payment Date” for
a Fixed Rate Note) and on the Maturity Date (as defined below). Interest on Fixed Rate Notes will be computed on the basis of a 360-day year of twelve 30-day months. 
 If any Interest Payment Date or the Maturity Date of a Fixed Rate Note falls on a day that is not a Business Day, the required payment of principal, premium, if any, and/or interest will be payable on the next
succeeding Business Day, and no additional interest will accrue in respect of the payment made on that next succeeding Business Day. 
  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    23 

 (d) The interest rate on each Floating Rate Note for each Interest Reset Period (as defined below) will be determined by
reference to an interest rate basis (a “Base Rate”) plus or minus a number of basis points (one basis point equals one-hundredth of a percentage point) (the “Spread”), if any, and/or multiplied by a certain percentage (the
“Spread Multiplier”), if any, until the principal thereof is paid or made available for payment. The Supplement will designate which of the following Base Rates is applicable to the related Floating Rate Note: (a) the CD Rate (a
“CD Rate Note”), (b) the Commercial Paper Rate (a “Commercial Paper Rate Note”), (c) the Federal Funds Rate (a “Federal Funds Rate Note”), (d) LIBOR (a “LIBOR Note”), (e) the Prime Rate (a
“Prime Rate Note”), (f) the Treasury Rate (a “Treasury Rate Note”) or (g) such other Base Rate as may be specified in such Supplement. 
 The rate of interest on each Floating Rate Note will be reset daily, weekly, monthly, quarterly or semi-annually (the “Interest Reset Period”). The date or dates on which interest will be reset (each an
“Interest Reset Date”) will be, unless otherwise specified in the Supplement, in the case of Floating Rate Notes which reset daily, each Business Day, in the case of Floating Rate Notes (other than Treasury Rate Notes) that reset weekly,
the Wednesday of each week; in the case of Treasury Rate Notes that reset weekly, the Tuesday of each week; in the case of Floating Rate Notes that reset monthly, the third Wednesday of each month; in the case of Floating Rate Notes that reset
quarterly, the third Wednesday of March, June, September and December; and in the case of Floating Rate Notes that reset semiannually, the third Wednesday of the two months specified in the Supplement. If any Interest Reset Date for any Floating
Rate Note is not a Business Day, such Interest Reset Date will be postponed to the next day that is a Business Day, except that in the case of a LIBOR Note, if such Business Day is in the next succeeding calendar month, such Interest Reset Date
shall be the immediately preceding Business Day. Interest on each Floating Rate Note will be payable monthly, quarterly or semiannually (the “Interest Payment Period”) and on the Maturity Date. Unless otherwise specified in the Supplement,
and except as provided below, the date or dates on which interest will be payable (each an “Interest Payment Date” for a Floating Rate Note) will be, in the case of Floating Rate Notes with a monthly Interest Payment Period, on the third
Wednesday of each month; in the case of Floating Rate Notes with a quarterly Interest Payment Period, on the third Wednesday of March, June, September and December; and in the case of Floating Rate Notes with a semiannual Interest Payment Period, on
the third Wednesday of the two months specified in the Supplement. In addition, the Maturity Date will also be an Interest Payment Date. 
 If any Interest
Payment Date for any Floating Rate Note (other than an Interest Payment Date occurring on the Maturity Date) would otherwise be a day that is not a Business Day, such Interest Payment Date shall be postponed to the next day that is a Business Day,
except that in the case of a LIBOR Note, if such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. If the Maturity Date of a Floating Rate Note falls on a day that is
not a Business Day, the payment of principal and interest will be made on the next succeeding Business Day, and no interest on such payment shall accrue for the period from and after such maturity. 
 Interest payments on each Interest Payment Date for Floating Rate Notes will include accrued interest from and including the Issue Date or from and including the last
date in respect of which interest has been paid, as the case may be, to, but excluding, such Interest Payment Date. On the Maturity Date, the interest payable on a Floating Rate Note will include interest accrued to, but excluding, the Maturity
Date. Accrued interest will be calculated by multiplying the principal amount of a Floating Rate Note by an accrued interest factor. This accrued interest factor will be computed by adding the interest factors 

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    24 

 
calculated for each day in the period for which accrued interest is being calculated. The interest factor (expressed as a decimal) for each such day will be
computed by dividing the interest rate applicable to such day by 360, in the cases where the Base Rate is the CD Rate, Commercial Paper Rate, Federal Funds Rate, LIBOR or Prime Rate, or by the actual number of days in the year, in the case where the
Base Rate is the Treasury Rate. The interest rate in effect on each day will be (i) if such day is an Interest Reset Date, the interest rate with respect to the Interest Determination Date (as defined below) pertaining to such Interest Reset
Date, or (ii) if such day is not an Interest Reset Date, the interest rate with respect to the Interest Determination Date pertaining to the next preceding Interest Reset Date, subject in either case to any adjustment by a Spread and/or a
Spread Multiplier. 
 The “Interest Determination Date” where the Base Rate is the CD Rate or the Commercial Paper Rate will be the second Business
Day next preceding an Interest Reset Date. The Interest Determination Date where the Base Rate is the Federal Funds Rate or the Prime Rate will be the Business Day next preceding an Interest Reset Date. The Interest Determination Date where the Base
Rate is LIBOR will be the second London Business Day next preceding an Interest Reset Date. The Interest Determination Date where the Base Rate is the Treasury Rate will be the day of the week in which such Interest Reset Date falls when Treasury
Bills are normally auctioned. Treasury Bills are normally sold at auction on Monday of each week, unless that day is a legal holiday, in which case the auction is held on the following Tuesday or the preceding Friday. If an auction is so held on the
preceding Friday, such Friday will be the Interest Determination Date pertaining to the Interest Reset Date occurring in the next succeeding week. 
 The
“Index Maturity” is the period to maturity of the instrument or obligation from which the applicable Base Rate is calculated. 
 The
“Calculation Date,” where applicable, shall be the earlier of (i) the tenth calendar day following the applicable Interest Determination Date or (ii) the Business Day preceding the applicable Interest Payment Date or Maturity
Date. 
 All times referred to herein reflect New York City time, unless otherwise specified. 
 The Issuer shall specify in writing to the Issuing and Paying Agent which party will be the calculation agent (the “Calculation Agent”) with respect to the Floating Rate Notes. The Calculation Agent will
provide the interest rate then in effect and, if determined, the interest rate which will become effective on the next Interest Reset Date with respect to such Floating Rate Note to the Issuing and Paying Agent as soon as the interest rate with
respect to such Floating Rate Note has been determined and as soon as practicable after any change in such interest rate. 
 All percentages resulting from
any calculation on Floating Rate Notes will be rounded to the nearest one hundred-thousandth of a percentage point, with five-one millionths of a percentage point rounded upwards. For example, 9.876545% (or .09876545) would be rounded to 9.87655%
(or .0987655). All dollar amounts used in or resulting from any calculation on Floating Rate Notes will be rounded, in the case of U.S. dollars, to the nearest cent or, in the case of a foreign currency, to the nearest unit (with one-half cent or
unit being rounded upwards). 
 CD Rate Notes 
 “CD Rate” means the rate on any Interest Determination Date for negotiable certificates of deposit having the Index Maturity as published by the Board of Governors of the Federal Reserve System (the “FRB”) in
“Statistical Release H.15(519), Selected Interest Rates” or any successor publication of the FRB (“H.15(519)”) under the heading “CDs (Secondary Market)”. 
  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    25 

 If the above rate is not published in H.15(519) by 3:00 p.m. on the Calculation Date, the CD Rate will be
the rate on such Interest Determination Date set forth in the daily update of H.15(519), available through the world wide website of the FRB at http://www.federalreserve.gov/releases/h15/Update, or any successor site or publication or other
recognized electronic source used for the purpose of displaying the applicable rate (“H.15 Daily Update”) under the caption “CDs (Secondary Market)”. 
 If such rate is not published in either H.15(519) or H.15 Daily Update by 3:00 p.m. on the Calculation Date, the Calculation Agent will determine the CD Rate to be the arithmetic mean of the secondary market offered
rates as of 10:00 a.m. on such Interest Determination Date of three leading nonbank dealers in negotiable U.S. dollar certificates of deposit in New York City selected by the Calculation Agent for negotiable U.S. dollar certificates of deposit of
major United States money center banks of the highest credit standing in the market for negotiable certificates of deposit with a remaining maturity closest to the Index Maturity in the denomination of $5,000,000. 
 If the dealers selected by the Calculation Agent are not quoting as set forth above, the CD Rate will remain the CD Rate then in effect on such Interest
Determination Date. 
 Commercial Paper Rate Notes 
 “Commercial Paper Rate” means the Money Market Yield (calculated as described below) of the rate on any Interest Determination Date for commercial paper having the Index Maturity, as published in H.15(519)
under the heading “Commercial Paper-Nonfinancial”. 
 If the above rate is not published in H.15(519) by 3:00 p.m. on the
Calculation Date, then the Commercial Paper Rate will be the Money Market Yield of the rate on such Interest Determination Date for commercial paper of the Index Maturity as published in H.15 Daily Update under the heading “Commercial
Paper-Nonfinancial”. 
 If by 3:00 p.m. on such Calculation Date such rate is not published in either H.15(519) or H.15 Daily Update,
then the Calculation Agent will determine the Commercial Paper Rate to be the Money Market Yield of the arithmetic mean of the offered rates as of 11:00 a.m. on such Interest Determination Date of three leading dealers of U.S. dollar commercial
paper in New York City selected by the Calculation Agent for commercial paper of the Index Maturity placed for an industrial issuer whose bond rating is “AA,” or the equivalent, from a nationally recognized statistical rating organization.

 If the dealers selected by the Calculation Agent are not quoting as mentioned above, the Commercial Paper Rate with respect to such
Interest Determination Date will remain the Commercial Paper Rate then in effect on such Interest Determination Date. 
 “Money Market
Yield” will be a yield calculated in accordance with the following formula: 
  

									
	 	 	 	 	D x 360	  	 	  	 
	Money Market Yield	 	=	 	  
	  	x 100	  	
		 		 	360 - (D x M)	  		  	
		 		 		  		  	

  

 n    Commercial Paper Dealer Agreement 4(2)
Program    n    26 

 where “D” refers to the applicable per annum rate for commercial paper quoted on a bank
discount basis and expressed as a decimal and “M” refers to the actual number of days in the interest period for which interest is being calculated. 
 Federal Funds Rate Notes 
 “Federal Funds Rate” means the rate on any Interest Determination Date for federal funds
as published in H.15(519) under the heading “Federal Funds (Effective)” and displayed on Moneyline Telerate (or any successor service) on page 120 (or any other page as may replace the specified page on that service) (“Telerate Page
120”). 
 If the above rate does not appear on Telerate Page 120 or is not so published by 3:00 p.m. on the Calculation Date, the Federal
Funds Rate will be the rate on such Interest Determination Date as published in H.15 Daily Update under the heading “Federal Funds/(Effective)”. 
 If such rate is not published as described above by 3:00 p.m. on the Calculation Date, the Calculation Agent will determine the Federal Funds Rate to be the arithmetic mean of the rates for the last transaction in
overnight U.S. dollar federal funds arranged by each of three leading brokers of Federal Funds transactions in New York City selected by the Calculation Agent prior to 9:00 a.m. on such Interest Determination Date. 
 If the brokers selected by the Calculation Agent are not quoting as mentioned above, the Federal Funds Rate will remain the Federal Funds Rate then in
effect on such Interest Determination Date. 
 LIBOR Notes 
 The London Interbank offered rate (“LIBOR”) means, with respect to any Interest Determination Date, the rate for deposits in U.S. dollars having the Index Maturity that appears on the Designated LIBOR Page
as of 11:00 a.m., London time, on such Interest Determination Date. 
 If no rate appears, LIBOR will be determined on the basis of the rates
at approximately 11:00 a.m., London time, on such Interest Determination Date at which deposits in U.S. dollars are offered to prime banks in the London interbank market by four major banks in such market selected by the Calculation Agent for a term
equal to the Index Maturity and in principal amount equal to an amount that in the Calculation Agent’s judgment is representative for a single transaction in U.S. dollars in such market at such time (a “Representative Amount”). The
Calculation Agent will request the principal London office of each of such banks to provide a quotation of its rate. If at least two such quotations are provided, LIBOR will be the arithmetic mean of such quotations. If fewer than two quotations are
provided, LIBOR for such interest period will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in New York City, on such Interest Determination Date by three major banks in New York City, selected by the Calculation Agent, for
loans in U.S. dollars to leading European banks, for a term equal to the Index Maturity and in a Representative Amount; provided, however, that if fewer than three banks so selected by the Calculation Agent are providing such quotations, the then
existing LIBOR rate will remain in effect for such Interest Payment Period. 
 “Designated LIBOR Page” means the display designated
as page “3750” on Moneyline Telerate (or such other page as may replace the 3750 page on that service or such other service or services as may be nominated by the British Bankers’ Association for the purposes of displaying London
interbank offered rates for U.S. dollar deposits).

 Prime Rate Notes 
 “Prime Rate” means the rate on any Interest Determination Date as published in H.15(519) under the heading “Bank Prime Loan”. 
 If the above rate is not published in H.15(519) prior to 3:00 p.m. on the Calculation Date, then the Prime Rate will be the rate on such Interest
Determination Date as published in H.15 Daily Update opposite the caption “Bank Prime Loan”. 
 If the rate is not published prior
to 3:00 p.m. on the Calculation Date in either H.15(519) or H.15 Daily Update, then the Calculation Agent will determine the Prime Rate to be the arithmetic mean of the rates of interest publicly announced by each bank that appears on the Reuters
Screen US PRIME1 Page (as defined below) as such bank’s prime rate or base lending rate as of 11:00 a.m., on that Interest Determination Date. 
 If fewer than four such rates referred to above are so published by 3:00 p.m. on the Calculation Date, the Calculation Agent will determine the Prime Rate to be the arithmetic mean of the prime rates or base lending rates quoted on the
basis of the actual number of days in the year divided by 360 as of the close of business on such Interest Determination Date by three major banks in New York City selected by the Calculation Agent. 
 If the banks selected are not quoting as mentioned above, the Prime Rate will remain the Prime Rate in effect on such Interest Determination Date.

 “Reuters Screen US PRIME1 Page” means the display designated as page “US PRIME1” on the Reuters Monitor Money Rates
Service (or such other page as may replace the US PRIME1 page on that service for the purpose of displaying prime rates or base lending rates of major United States banks). 
 Treasury Rate Notes 
 “Treasury Rate” means: 
 (1) the rate from the auction held on the Interest Determination Date (the “Auction”) of direct obligations of the United States (“Treasury
Bills”) having the Index Maturity specified in the Supplement under the caption “INVESTMENT RATE” on the display on Moneyline Telerate (or any successor service) on page 56 (or any other page as may replace that page on that service)
(“Telerate Page 56”) or page 57 (or any other page as may replace that page on that service) (“Telerate Page 57”), or 
 (2) if the rate referred to in clause (1) is not so published by 3:00 p.m. on the related Calculation Date, the Bond Equivalent Yield (as defined below) of the rate for the applicable Treasury Bills as published in H.15 Daily Update,

 (4) if the rate referred to in clause (3) is not so announced by the United States Department of the Treasury, or if the Auction is not held, the Bond Equivalent Yield of the rate on the particular Interest
Determination Date of the applicable Treasury Bills as published in H.15(519) under the caption “U.S. Government Securities/Treasury Bills/Secondary Market”, or 
 (5) if the rate referred to in clause (4) not so published by 3:00 p.m. on the related Calculation Date, the rate on the particular Interest Determination Date of the applicable Treasury Bills as published in
H.15 Daily Update, under the caption “U.S. Government Securities/Treasury Bills/Secondary Market”, or 
 (6) if the rate referred to
in clause (5) is not so published by 3:00 p.m. on the related Calculation Date, the rate on the particular Interest Determination Date calculated by the Calculation Agent as the Bond Equivalent Yield of the arithmetic mean of the secondary
market bid rates, as of approximately 3:30 p.m. on that Interest Determination Date, of three primary United States government securities dealers selected by the Calculation Agent, for the issue of Treasury Bills with a remaining maturity closest to
the Index Maturity specified in the Supplement, or 
 (7) if the dealers so selected by the Calculation Agent are not quoting as mentioned in
clause (6), the Treasury Rate in effect on the particular Interest Determination Date. 
 “Bond Equivalent Yield” means a yield
(expressed as a percentage) calculated in accordance with the following formula: 
  

									
	 	 	 	 	D x N	  	 	  	 
	Bond Equivalent Yield	 	=	 	  
	  	x 100	  	
		 		 	360 - (D x M)	  		  	
		 		 		  		  	

 where “D” refers to the applicable per annum rate for Treasury Bills quoted on a bank
discount basis and expressed as a decimal, “N” refers to 365 or 366, as the case may be, and “M” refers to the actual number of days in the applicable Interest Reset Period. 
  

	 	3.	Final Maturity. The Stated Maturity Date for any Note will be the date so specified in the Supplement, which shall be no later than 397 days from the date of issuance. On its
Stated Maturity Date, or any date prior to the Stated Maturity Date on which the particular Note becomes due and payable by the declaration of acceleration, each such date being referred to as a Maturity Date, the principal amount of each Note,
together with accrued and unpaid interest thereon, will be immediately due and payable. 

  

	 	4.	 Events of Default. The occurrence of any of the following shall constitute an “Event of Default” with respect to a Note: (i) default in any
payment of principal of or interest on such Note (including on a redemption thereof); (ii) the Issuer makes any compromise arrangement with its creditors generally including the entering into any form of moratorium with its creditors generally;
(iii) a court having jurisdiction shall enter a decree or order for relief in respect of the Issuer in an involuntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or there shall be

of the assets of the Issuer and any such decree, order or appointment is not removed, discharged or withdrawn within 60 days thereafter; or (iv) the Issuer shall commence a voluntary case under any applicable bankruptcy, insolvency or other
similar law now or hereafter in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of or taking possession by a receiver, administrator, liquidator, assignee, custodian,
trustee or sequestrator (or similar official), with respect to the whole or substantially the whole of the assets of the Issuer or make any general assignment for the benefit of creditors. Upon the occurrence of an Event of Default, the principal of
each obligation evidenced by such Note (together with interest accrued and unpaid thereon) shall become, without any notice or demand, immediately due and payable. 

  

	 	5.	Obligation Absolute. No provision of the Issuing and Paying Agency Agreement under which the Notes are issued shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of and interest on each Note at the times, place and rate, and in the coin or currency, herein prescribed.
