	6 	 Applied to Mr. Duranton, who was subsequently approved for appointment to the management committee. 

 
your principal office, and principal place of employment, shall be at the Company’s principal executive offices in New York City, but you acknowledge and agree that the performance of your
duties hereunder may require significant business travel.

accordance with Section 5 of this Agreement. 
 3. Compensation and Benefits. 

(a) Base Salary. During the Term, you shall receive a base salary (“Base Salary”) of no less than the
amount set forth on Appendix A, per annum, payable in accordance with the Company’s standard payroll practices but no less frequently than monthly. Your Base Salary shall be reviewed no less frequently than annually during the

of the Company’s annual incentive plan. 
 (c) Long Term Incentive Awards. During the Term, you shall be

 (d) Withholding. The Company may withhold all applicable Federal, state and
local taxes and other amounts as may be required by law or agreed upon by the Parties with respect to compensation payable to you pursuant to this Agreement. 
 (e) Vacation. You shall be entitled during the Term to the number of weeks of vacation per calendar year provided to U.S. senior executives of the Company generally, but in no event fewer
than four weeks’ vacation per calendar year. 
 (f) Employee Benefits.10 During the Term, you will participate in all employee benefit plans,
programs and arrangements, expense reimbursement arrangements, and all perquisites and fringe benefits, that are generally available to U.S. senior executives of the Company (the “Company Arrangements”), on terms and conditions no
less favorable to you than those applying to other U.S. senior executives of the Company generally. The Company shall also provide you with [a Company-paid parking space]11[use of a car and driver]12. 
 (g) D&O Insurance. A directors’ and officers’ liability insurance policy (or policies) shall be kept in place, during the Term and for six years thereafter, providing coverage
that is no less favorable to you in any respect (including, without limitation, with respect to scope, exclusions, amounts and deductibles) than the coverage then being provided to any other present or former officer or director of the Company.

 (h) Indemnification. The Company shall indemnify you and advance expenses to you to the
extent similarly situated U.S. senior executives of the Company are indemnified and advanced expenses in accordance with the Company’s bylaws as in effect from time to time, [and following termination of your employment, you shall continue to
be afforded such rights on terms and conditions no less favorable than active U.S. senior executive
officers.]13 

(i) Golden Parachute Tax. 
 (i) If the aggregate of all amounts and benefits due to you, under this Agreement or any other plan, program, agreement or arrangement of the Company or any of its Affiliates (or any payments, benefits or
entitlements by any entity that effectuates a related transaction), would constitute “parachute payments” as such term is defined in and under Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”)
(collectively, “Change in Control Benefits”), and would result in the imposition of excise taxes pursuant to Section 4999 of the Code, the Company will make an additional payment to you in an amount (the “Gross-Up
Payment”) such that, after payment all taxes and any interest or penalties imposed with respect to such taxes (including, without limitation, federal, state, local income, employment, excise and 

 
  

	10 	 Messrs. Halvey and Duranton are also entitled to reimbursement of fees, to a maximum of $15,000, in connection with the retention of tax advisors.

	11 	 For Messrs. Halvey, Duranton, Geltzeiler and Leibowitz. 

	12 	 For Mr. Niederauer. 

	13 	 For Messrs. Niederauer, Halvey, Duranton and Leibowitz.

other similar taxes, but excluding any taxes imposed under Section 409A of the Code) (the “Parachute Tax”) on both the Change in Control Benefits and the Gross-Up Payment,
you will be in the same position as if no Parachute Tax had been imposed. Any Gross-Up Payment shall be timely paid by the Company on your behalf directly to the appropriate taxing authorities when due, but in all events no later than the last day
of the calendar year after the calendar year in which the Parachute Tax shall be paid. The determinations with respect to this Section 3(i)(i) shall be made by an independent auditor (the “Auditor”) paid by the Company. The
Auditor shall be a nationally-recognized United States public accounting firm chosen by the Company and approved by you (which approval shall not be unreasonably withheld or delayed). Notwithstanding the foregoing provisions of this
Section 3(i)(i), if it shall be determined that you are entitled to the Gross-Up Payment, but that the Parachute Value (as defined below) of all Change in Control Benefits does not exceed 110% of the Safe Harbor Amount (as defined below), then
no Gross-Up Payment shall be made to you and the amounts payable under this Agreement shall be reduced so that the Parachute Value of all Change in Control Benefits, in the aggregate, equals the Safe Harbor Amount minus $5,000.00. The reduction of
the amounts payable hereunder which constitute Change in Control Benefits, if applicable, shall be made by reducing the payments and benefits under the following sections in the following order: (i) Section 6(b)(iii), [(ii)
Section 6(b)(ii)]14,
(iii) Section 6(b)(iv), (iv) [Section 6(b)(v)]15 [and (v) Section 6(b)(vi)]16 [Section 6(b)(vii)]17. For purposes of reducing the Change in Control Benefits to the Safe Harbor Amount minus $5,000, only amounts payable under this Agreement (and no other payments) shall be reduced. If the reduction of
the amounts payable under this Agreement would not result in a reduction of the Parachute Value of all Change in Control Benefits to the Safe Harbor Amount minus $5,000, no amounts payable under the Agreement or otherwise shall be reduced pursuant
to this Section 3(i)(i). The Company’s obligation to make Gross-Up Payments under this Section 3(i) shall not be conditioned upon your termination of employment. 

(ii) It is possible that after the determinations and selections made pursuant to Section 3(i)(i) you will receive Change in
Control Benefits and Gross-Up Payments that are, in the aggregate, either more or less than the limitations provided in Section 3(i)(i) above (hereafter referred to as an “Excess Payment” or “Underpayment”,
respectively). If it is established, pursuant to a final determination of a court or an Internal Revenue Service proceeding that has been finally and conclusively resolved, that an Excess Payment has been made, then you shall refund the Excess
Payment to the Company promptly on demand, together with an additional payment in an amount equal to the product obtained by multiplying the Excess Payment times the applicable annual federal rate (as determined in and under Section 1274(d) of
the Code) times a fraction whose numerator is the number of days elapsed from the date of your receipt of such Excess Payment through the date of such refund and whose denominator is 365. In the event that it is determined (x) by arbitration
under Section 8 below, (y) by a court of competent jurisdiction, or (z) by the Auditor upon request by you or the Company, that an Underpayment

has occurred, the Company shall pay an amount equal to the Underpayment to you within 10 days of such determination together with an additional payment in an amount equal to the product obtained
by multiplying the Underpayment times the applicable annual federal rate (as determined in and under Section 1274(d) of the Code) times a fraction whose numerator is the number of days elapsed from the date of the
Underpayment through the date of such payment and whose denominator is 365. 
 (iii) Any Gross-Up Payment, as determined
pursuant to this Section 3(i), shall be paid by the Company and remitted to the relevant tax authorities when such payment is due, provided that in no event shall such payment be made later than the end of your taxable year next following your
taxable year in which the Parachute Tax on a Change in Control Benefit are remitted to the Internal Revenue Service or any other applicable taxing authority or, in the case of amounts relating to a claim described in Section 3(i)(ii) that does
not result in the remittance of any federal, state, local and foreign income, excise, social security and other taxes, the calendar year in which the claim is finally settled or otherwise resolved. 

(iv) Definitions. The following terms shall have the following meanings for purposes of this Section 3(i). 

“Parachute Value” of a Change in Control Benefit shall mean the present value as of the date of the change of control
for purposes of Section 280G of the Code of the portion of such Change in Control Benefit that constitutes a “parachute payment” under Section 280G(b)(2) of the Code and its implementing regulations, as determined by the Auditor
for purposes of determining whether and to what extent the Parachute Tax will apply to such Change in Control Benefit. 
 The
“Safe Harbor Amount” means 2.99 times your “base amount,” within the meaning of Section 280G(b)(3) of the Code and its implementing regulations. 

(j) 409A Compliance. 
 (i) Full Compliance. It is the intent of the Parties that all compensation and benefits payable or provided to you (whether under this Agreement or otherwise) shall fully comply with the
requirements of Section 409A of the Code. Within the time period permitted by the applicable Treasury Regulations, the Company may, subject to your written approval (such approval not to be unreasonably withheld), modify the Agreement, in the
least restrictive manner necessary without diminution of value, in order to cause the provisions of the Agreement to comply with the requirements of Section 409A of the Code, so as to avoid the imposition of taxes and penalties on you pursuant
to Section 409A of the Code. 
 (ii) Specified Employee. Notwithstanding anything contained in this Agreement to
the contrary, if you are a “specified employee” (determined in accordance with Section 409A of the Code and Treasury Regulation Section 1.409-3(i)(2)) as of the date that your employment terminates and you have experienced a
“separation from service” (within the meaning of Section 409A of the Code) (such date, the “Termination Date”), and if any payment, benefit or entitlement provided for in this Agreement or otherwise both
(i) constitutes a “deferral of compensation” within the meaning of Section 409A of the Code (“Nonqualified Deferred  

  
 5 

 
Compensation”) and (ii) cannot be paid or provided in a manner otherwise provided herein or otherwise without subjecting you to additional tax, interest and/or penalties under
Section 409A of the Code, then any such payment, benefit or entitlement that is payable during the first 6 months following the Termination Date shall be paid or provided to you in a lump sum cash payment to be made on the earlier of
(x) your death or (y) the first business day of the seventh calendar month immediately following the month in which the Termination Date occurs. 
 4. Non-competition and Non-solicitation. You agree that during your employment with the Company and for the 12-month period of time following the termination of your employment with the
Company, you will not, without the prior written consent of the Chief Executive Officer of the Company, directly or indirectly: 
 (a) own, control, manage, loan money to, represent, render any service or advice to or act as an officer, director, employee, agent, representative, partner or independent contractor of any securities
exchange, “ECN” or other such entity or similar direct seller of market data in the financial services business, whose business competes with the businesses of the Company or its majority-owned subsidiaries, in North America or Europe as
such businesses were being conducted, or which the Company was actively planning to enter, during your employment [if the breach or alleged breach occurs during your employment or on the date of your termination of employment if the breach or
alleged breach occurs thereafter]18 (“Competitive
Activities”); provided, however, that (i) the foregoing shall not prohibit you from passive ownership of securities in any publicly traded company that is engaged in any such business as long as you do not own more than five percent
(5%) or more of any class of the equity securities of such company, and (ii) nothing in this Agreement shall preclude you from accepting employment with, or providing services to, any entity that engages in Competitive Activities so long
as you work solely in a subsidiary, division or other distinct unit of such any entity, including an Affiliate, that does not engage, and is not actively planning to engage, in Competitive Activities. 

(b) Solicit, induce, influence, encourage, or attempt to solicit, induce, influence or encourage, either directly or indirectly, any
person who is, at the time of such solicitation, inducement, influence, encouragement or attempt, or was during the previous six months, employed by the Company to terminate his or her employment relationship with the Company or hire or employ or
engage any such person or otherwise interfere with any such person’s employment by or association with the Company; 
 (c)
Induce, influence, encourage, or attempt to induce, influence or encourage, either directly or indirectly, any third party to terminate such party’s business relationship with the Company or otherwise interfere with any business or contractual
relationship of the Company; or 
 (d) Serve as a board member on any board of directors of any company engaged in Competitive
Activities, except as provided in Section 4(a)(ii). 
  

 

	18 	 For Messrs. Geltzeiler and Halvey.

 You acknowledge and agree that: (i) the purposes of the foregoing covenants are to protect the goodwill
and confidential or proprietary information and trade secrets of the Company, and to prevent you from interfering with the business of the Company; (ii) it would be impractical and excessively difficult to determine the actual damages of the
Company in the event you breach any of the covenants of this Section 4; (iii) remedies at law for any breach of your obligations under this Section 4 would be inadequate; and (iv) the terms of the covenants are sufficiently
limited to protect the legitimate interests of the Company and impose no undue hardship on you. You therefore agree that if you commit any breach of a covenant under this Section 4 or threaten to commit any such breach, the Company shall have
the right (in addition to any other right or remedy that may be available to it) to injunctive relief from a court of competent jurisdiction located in the State of New York or otherwise, without posting any bond or other security and without the
necessity of proof of actual damage. With respect to any provision of this Section 4 finally determined by a court of competent jurisdiction to be unenforceable, this Agreement or any provision hereof shall be reformed so that it is enforceable
to the maximum extent permitted by law. 
 5. Termination. Your employment hereunder, and the Term, shall
terminate upon the first to occur of the following events: 
 (a) Death. You die. 

(b) Disability. You have been unable, for 120 or more days out of 180 consecutive days, to perform your duties under this
Agreement, as a result of physical or mental illness, injury or incapacity, and the Company shall have communicated to you, by written notice, the fact of your termination, which termination shall be effective on the 30th day after receipt of such
notice by you, unless you return to full-time performance of your duties hereunder prior to such 30th day. Upon the timely request and at the expense of Company, any such physical or mental illness, injury or incapacity shall be confirmed by an
independent medical professional acceptable to both Parties, before your employment can be terminated for disability. 
 (c)
For Cause. Your employment hereunder may only be terminated by the Company for Cause by complying with the provisions of this Section 5(c). 
 (i) You shall be given written notice by the Board of Directors of the Company (the “Board”) of its intention to terminate you for Cause, such notice (x) to state in detail the particular
circumstances that constitute the grounds on which the proposed termination for Cause is based and (y) to be given no later than 90 days after the Board, as a whole, is first made aware of such circumstances. The question of whether Cause
existed may be challenged through arbitration in accordance with Section 8. 
 (ii) For purposes of this Agreement,
“Cause” shall mean: (1) your conviction, or a plea of nolo contendere, to a felony involving moral turpitude; (2) willful misconduct or gross neglect by you resulting, in either case, in material harm to the
Company; (3) a willful continued failure by you to carry out the reasonable and lawful directions of the Board [or Chief 

  
 7 

 
Executive Officer]19; (4) fraud, embezzlement, theft or dishonesty of a material nature by you against the Company or a willful violation by you of a policy or procedure of the Company that has been communicated in
writing to you, resulting, in any case, in material harm to the Company; or (5) a willful material breach by you of Section 4 of this Agreement, which breach is not cured by you on 30 days written notice from the Board requesting cure. An
act or failure to act shall not be “willful” if (x) done by you in good faith or (y) you reasonably believed that such action or inaction was in the best interests of the Company. 

(d) Without Cause. The Company may terminate your employment hereunder at any time, for any reason or no reason, by giving
you four weeks’ prior written notice of the termination. No such termination of your employment hereunder shall be deemed a breach of this Agreement. 
 (e) For Good Reason. You may terminate your employment hereunder for “Good Reason,” which, for purposes of this Agreement shall mean, without your prior written consent, the
occurrence of any of the following events or actions20:
(1) a material reduction of your Base Salary or Target Bonus, which for this purpose shall mean one or more reductions that, individually or in the aggregate, exceed 5% of your highest Base Salary or Target Bonus, as applicable; (2) an
actual relocation of your principal office that is more than 50 miles from New York, NY[, London or Paris]21; (3) a [material]22 diminution of your title, [a material diminution of your]23 authority, duties or responsibilities, or the assignment to you of titles, authority, duties or responsibilities that are materially inconsistent with your titles, authority, duties and/or 

 
  

	19 	 For Messrs. Geltzeiler and Leibowitz. 

	20 	 For Mr. Niederauer, the events and actions constituting Good Reason are: “(1) a material reduction of your Base Salary or Target Bonus, which
for this purpose shall mean one or more reductions that, individually or in the aggregate, exceed 5% of your highest Base Salary or Target Bonus, as applicable, excluding any reduction applicable equally to all U.S. senior executives following an
extraordinary decline in the Company’s earnings, share price or public image; (2) an actual non-temporary relocation of your principal office to a location that is more than 50 miles from New York, NY where such relocation is not
occasioned by exigent health and safety conditions; (3) a material negative and non-temporary change, diminution or reduction, for any reason including any such change by reason of a Change in Control, in your authority, powers, titles,
reporting relationship, responsibilities or duties as Chief Executive Officer as set forth in this Agreement, including, by way of example, requiring a reporting relationship to an Executive Chairman, or other reporting relationship that has the
practical effect of materially diminishing your current authority, powers, duties or responsibilities, or assigning you duties that are materially and negatively inconsistent with your position as Chief Executive Officer, in either case, of a
magnitude that changes the fundamental current character of your job as Chief Executive Officer to such an extent as to constitute a de facto demotion; (4) a change in your reporting so that you cease to report to the Board of Directors
of the Company (or, after a Change in Control (as defined in the 2008 Stock Incentive Plan) and if applicable, the Board of Directors of the ultimate parent of the Company); (5) failure to nominate you as a Director at the first election
following your removal from the Board; (6) failure of the Company to obtain the assumption in writing of its obligations under this Agreement by any successor to all or substantially all of the assets of the Company within 15 days after a
merger, consolidation, sale or similar transaction; or (7) a material breach by the Company of this Agreement. 

	21 	 For Mr. Duranton. 

	22 	 For Mr. Leibowitz. 

	23 	 For Messrs. Geltzeiler, Duranton and Halvey.

responsibilities under this Agreement; (4) a change in your reporting so that you cease to report to the [Title]24 (or, after a Change in Control (as defined in the 2008 Stock Incentive Plan) and if applicable, the [Title]24 of the ultimate parent of the Company); (5) a failure of the
Company to obtain the assumption in writing of its obligations under this Agreement by any successor to all or substantially all of the assets of the Company within 15 days after a merger, consolidation, sale or similar transaction; [or] (6) a
material breach by the Company of this Agreement; [or (7) [you are no longer the sole and top legal officer of the Company and its Affiliates]25[you are no longer the most senior human resources officer of the Company and its Affiliates]26. In order to invoke a termination for Good Reason, you shall provide
written notice to the Company of the existence of one or more of the conditions described in clauses (1) through [(6)][(7)] within 90 [180]27 days following your knowledge of the initial existence of such condition or conditions (the “Good Reason
Notice”), and the Company shall have 30 days following receipt of such Good Reason Notice (the “Cure Period”) during which it may remedy the condition. In the event that the Company fails to remedy the condition
constituting Good Reason during the applicable Cure Period, you must terminate employment, if at all, within two years following the existence of the condition for which the Good Reason Notice is given in order for such termination as a result of
such condition to constitute a termination for Good Reason. 
 (f) Without Good Reason. You may terminate your
employment hereunder at any time, for any reason or no reason, by giving four weeks’ prior written notice of termination to the Company. No such termination of your employment hereunder shall be deemed a breach of this Agreement. 

6. Benefits Upon Termination of Your Employment. In the event that your employment hereunder is terminated, for any or no
reason, you shall be entitled to the following compensation and benefits: 
 (a) Any Termination. On any
termination of your employment hereunder, you shall be entitled to the following benefits: 
 (i) prompt payment of any accrued
but unpaid Base Salary through the Termination Date, payable no later than the first regularly scheduled payroll date following the Termination Date; 
 (ii) prompt lump-sum payment in respect of your accrued but unused vacation days, payable as soon as practicable following the Termination Date; 

 
  

	24 	 For Mr. Niederauer, the Board of Directors; for Messrs. Geltzeiler, Halvey, Duranton and Leibowitz, the Chief Executive Officer.

	25 	 Applies only to Mr. Halvey. 

	26 	 Applies only to Mr. Duranton. 

	27 	 For Messrs. Geltzeiler, Duranton and Halvey. 

  
 9 

 (iii) prompt payment of any bonuses that were earned but not yet paid or deferred as of the
Termination Date, payable on the dates that such amounts would have been paid had your employment continued through the date of such payments; and 
 (iv) any other or additional payment, entitlement and/or benefit in accordance with the applicable terms of any plan, policy, program or arrangement of, or any agreement with, the Company or any
Affiliate. 
 (b) Termination without Cause or with Good Reason.28 In the event that your employment hereunder is terminated
(x) by the Company (other than for Cause in accordance with Section 5(c) or by reason of your disability) or (y) by you with Good Reason in accordance with Section 5(e), you shall receive the following benefits, provided, except
as set forth in Section 6(b)(i) below, that you execute (within 30 days after the Termination Date), and do not revoke, a release that is in the form attached hereto as Exhibit B, with such modifications as may be necessary to comply with
applicable law: 
 (i) the benefits described in Section 6(a) (you will receive these benefits regardless of whether you
execute a release); 
 (ii) a lump-sum payment, in cash, equal to the product obtained by multiplying (A) an annual bonus
for the calendar year of your termination, determined on the basis of Committee’s determination of the achievement of the applicable performance metrics for such calendar year [(provided that in no event shall the Committee exercise negative
discretion with respect to you in excess of that applied to active U.S. senior executives of the Company generally)] as if you had remained employed until the date annual bonuses are paid by the Company, times (B) a fraction whose numerator
equals the number of days you were employed during such calendar year and whose denominator is 365, such payment to be made at the time annual bonuses are paid by the Company (but in no event later than March 15 of the following calendar year);

 (iii) a lump sum cash amount equal to the product of (A) the Multiple (as defined below) and (B) the sum of
(1) the greater of (x) the Base Salary in effect on the Termination Date or (y) the Base Salary immediately prior to any reduction that would constitute Good Reason, plus (2) the greater of (a) the Target Bonus in effect on
the Termination Date or (b) the Target Bonus immediately prior to any reduction that would constitute Good Reason payable within 45 days of the Termination Date, in no event discounted for the time value of money; 

(iv) any equity compensation awards granted with respect to an annual bonus, including with respect to any bonus payable in accordance
with Section 6(a)(iii), shall become fully vested and non-forfeitable as of the Termination Date (and, in the case of restricted stock or restricted stock units, with prompt delivery of freely transferable shares); 

 
  

	28 	 Bracketed provisions in this Section 6(b) and in Section 6(c) only for Messrs. Niederauer, Leibowitz, Geltzeiler and Halvey.

  
 10 

 (v) you shall vest in a number of other equity compensation awards under the Company’s
long-term incentive plans that are subject to performance vesting conditions equal to the product obtained by multiplying (A) the number of shares subject to such awards, determined on the basis of [the Committee’s determination of the
achievement of] the applicable performance metrics [for such performance period (provided that in no event shall the Committee exercise negative discretion with respect to you in excess of that applied to active U.S. senior executives of the Company
generally)] as if you had remained employed until the date such awards would otherwise vest or be settled by the Company, times (B) a fraction, whose numerator equals the number of days you were employed during the applicable performance period
and whose denominator is the total number of days in the applicable performance period, such vesting and/or settlement to occur at the time such awards vest and/or are settled for active executives generally; 

(vi) as of the Termination Date, you shall vest in the equity compensation awards under the Company’s long-term incentive plans
that are subject to time-based vesting conditions as if you had remained employed through the vesting date immediately following the Termination Date (and, in the case of restricted stock or restricted stock units, with prompt delivery of freely
tradable shares); and 
 (vii) all health and life insurance benefits will continue for a number of years equal to the Multiple
following your termination of employment, at the active employee cost; provided, however, that, the health care benefits provided during the continuation period shall be provided in such a manner that such benefits (and the employer
paid portion of the costs and premiums thereof) are excluded from your income for federal income tax purposes and, if the Company reasonably determines that providing continued coverage under one or more of its health care benefit plans contemplated
herein could be taxable to you, the Company shall provide such benefits at a substantially comparable level through the purchase of individual or group insurance coverage that is not taxable to you; provided, further, however,
that if you become re-employed with another employer and are eligible to receive health care and/or life insurance benefits under another employer-provided plan, the health care benefits provided hereunder shall be secondary and the life insurance
benefits shall become supplemental to those provided under such other plan during such applicable period of eligibility. 
 The
“Multiple” shall mean (x) until and including the third anniversary of the Effective Date, two and (y) after the third anniversary of the effective date, one. Additionally, if such terminations are in connection with or in
anticipation of a Change in Control, or on or within two (2) years following a Change in Control, as defined in the Company’s 2008 Stock Incentive Plan, the Multiple shall mean two. 

(c) Termination for Death or Disability. In the event your employment hereunder is terminated by reason of your death or
disability (in accordance with Section 5(b)), you shall receive the following benefits: 
 (i) the benefits described in
Section 6(a); 
 (ii) a lump-sum payment, in cash, equal to the product obtained by multiplying (A) an annual bonus
for the calendar year of your termination, determined on the basis of 

  
 11 

 
Committee’s determination of the achievement of the applicable performance metrics for such calendar year [(provided that in no event shall the Committee exercise negative discretion with
respect to you in excess of that applied to active U.S. senior executives of the Company generally)] as if you had remained employed until the date annual bonuses are paid by the Company, times (B) a fraction whose numerator equals the number
of days you were employed during such calendar year and whose denominator is 365, such payment to be made at the time annual bonuses are paid by the Company (but in no event later than March 15 of the following calendar year); 

(iii) any equity compensation awards granted with respect to an annual bonus, including with respect to any bonus payable in accordance
with Section 6(a)(iii), shall become fully vested and non-forfeitable as of the Termination Date (and, in the case of restricted stock or restricted stock units, with prompt delivery of freely transferable shares); 

(iv) you shall vest in a number of other equity compensation awards under the Company’s long-term incentive plans that are subject
to performance vesting conditions equal to the product obtained by multiplying (A) the number of shares subject to such awards, determined on the basis [of the Committee’s determination of the achievement of] the applicable performance
metrics [for such performance period (provided that in no event shall the Committee exercise negative discretion with respect to you in excess of that applied to active U.S. senior executives of the Company generally)] as if you had remained
employed until the date such awards would otherwise vest or be settled by the Company, times (B) a fraction, whose numerator equals the number of days you were employed during the applicable performance period and whose denominator is the total
number of days in the applicable performance period, such vesting and/or settlement to occur at the time such awards vest and/or are settled for active executives generally; and 

(v) as of the Termination Date, you shall vest in the equity compensation awards under the Company’s long-term incentive plans that
are subject to time-based vesting conditions as if you had remained employed through the vesting date immediately following the Termination Date (with prompt delivery of freely tradable shares therewith). 

(d) No Mitigation; No Offset. In the event of any termination of your employment hereunder, you shall have no obligation to
seek other employment or otherwise mitigate the obligations of the Company under this Agreement, and there shall be no offset or recoupment against amounts, benefits or entitlements due to you under this Agreement on account of (x) any claim
that the Company or any of its Affiliates may have against you or (y) any remuneration or other benefit earned or received by you after such termination. 
 7. Notices. Any notice, consent, demand, request, or other communication given to a Person (as defined in Section 12(a)) in connection with this Agreement shall be in writing and shall
be deemed to have been given to such Person (x) when delivered personally to such Person or (y) provided that a written acknowledgment of receipt is obtained, five days after being sent by prepaid certified or registered mail, or
two days after being sent by a nationally recognized overnight courier, to the address (if any) specified below for such Person (or to such other address as such Person shall have specified by ten days’ advance notice given in accordance with
this Section 7).

 This Bond is one
of a duly authorized issue of Bonds of the Company (herein called the “Bonds”), in unlimited aggregate principal amount, of the series hereinafter specified, all issued and to be issued under and equally and ratably secured by a
Mortgage and Deed of Trust, dated July 1, 1939 (the “Original Mortgage”), executed by the Company to The Bank of New York Mellon Trust Company, N.A. (herein called the “Trustee”), as Trustee (as successor to
Harris Trust and Savings Bank), as amended by indentures supplemental thereto including the Forty-Second indenture supplemental thereto dated as of March 1, 2012 (herein called the “Supplemental Indenture”), between the Company
and the Trustee (said Original Mortgage, as so amended, being herein called the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a description of the properties mortgaged and
pledged, the nature and extent of the security, the rights of the bearers or registered owners of the Bonds and of the Trustee in respect thereto, and the terms and conditions upon which the Bonds are, and are to be, secured. The Bonds may be issued
in series, for various principal sums, may mature at different times, may bear interest at different rates and may otherwise vary as in the Indenture provided. This Bond is one of a series designated as the “First Mortgage Bonds, 4.125% Series
due 2042” (herein called “Bonds of the 2042 Series”) of the Company, issued under and secured by the Indenture executed by the Company to the Trustee. 

  
 11 

 To the extent permitted by, and as provided in the Indenture, modifications or alterations
of the Indenture or of any indenture supplemental thereto, and of the rights and obligations of the Company and of the holders of the Bonds and coupons, may be made with the consent of the Company by an affirmative vote of not less than 60% in
principal amount of the Bonds entitled to vote then outstanding, at a meeting of Bondholders called and held as provided in the Indenture, and by an affirmative vote of not less than 60% in principal amount of the Bonds of any series entitled to
vote then outstanding and affected by such modification or alteration, in case one or more but less than all of the series of Bonds then outstanding under the Indenture are so affected. No modification or alteration shall be made which will affect
the terms of payment of the principal of or premium, if any, or interest on, this Bond, which are unconditional. The Company has reserved the right to make certain amendments to the Indenture, without any consent or other action by holders of the
Bonds of this series (i) to the extent necessary from time to time to qualify the Indenture under the Trust Indenture Act of 1939, (ii) to delete the requirement that the Company meet a net earnings test as a condition to authenticating
additional Bonds or merging into another company, (iii) to make certain other amendments which make the provisions for the release of mortgaged property less restrictive and (iv) to make certain other amendments, all as more fully provided
in the Indenture and in the Supplemental Indenture. In addition, once all Bonds issued prior to January 1, 1997 are no longer outstanding, the Company will be permitted to issue additional Bonds in an amount equal to 70% of the value of net
bondable property additions not subject to an unfunded prior lien, as provided in the Original Mortgage. 
 This Bond is subject
to redemption by the Company on or after September 1, 2041 at any time in whole, or from time to time in part, at a redemption price equal to 100% of the principal amount of the Bond to be redeemed, plus accrued and unpaid interest on the Bond
to the redemption date. 
 This Bond is subject to redemption by the Company prior to September 1, 2041 at any time in
whole, or from time to time in part, at a price equal to the greater of: (a) 100% of the principal amount of the Bond to be redeemed, plus accrued and unpaid interest on the Bond to the redemption date, or (b) as determined by the
Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Bond to be redeemed (not including any portion of payments of interest accrued as of the redemption date) discounted to the
redemption date on a semi-annual basis at the Adjusted Treasury Rate plus twenty (20) basis points, plus accrued and unpaid interest on the Bond to the redemption date, in each of cases (a) and (b) as provided in the Supplemental
Indenture. 

  
 12 

 Such redemption in every case shall be effected upon notice given by: (1) first class
mail, postage prepaid, at least thirty days and not more than sixty days prior to the redemption date, to the registered owners of such Bonds at their addresses as the same shall appear on the transfer register of the Company; and (2) stating,
among other things, the redemption price and date, in each case, subject to the conditions of and as more fully set forth in the Indenture. 
 The redemption price will be calculated assuming a 360-day year consisting of twelve 30-day months. 
 A notice of redemption may provide that the optional redemption described in such notice is conditioned upon the occurrence of certain events before the redemption date. Such notice of conditional
redemption will be of no effect unless all such conditions to the redemption have occurred before the redemption date or have been waived by the Company. If any of these events fail to occur and are not waived by the Company, the Company will be
under no obligation to redeem the Bonds or pay the holders any redemption proceeds, and the Company’s failure to so redeem the Bonds will not be considered a default or event of default under the Indenture. In the event that any of these
conditions fail to occur or are not waived by the Company, the Company will promptly notify the Trustee in writing that the conditions precedent to such redemption have failed to occur and the Bonds will not be redeemed. 

Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the
bonds or portions of the bonds called for redemption. 
 “Adjusted Treasury Rate” means, with respect to any
redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for the redemption date. 
 “Business Day” means any day that is not a day on which
banking institutions in New York City are authorized or required by law or regulation to close. 
 “Comparable Treasury
Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Bonds that would be used, at the time of selection and in accordance with customary financial
practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Bonds. 

  
 13 

 “Comparable Treasury Price” means, with respect to any redemption date:

  

	 	•	 	 the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of the Reference Treasury
Dealer Quotations; or 

  

	 	•	 	 if the Quotation Agent obtains fewer than four Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so
received. 

 “Quotation Agent” means, as selected by the Company, one of the Reference
Treasury Dealers. 
 “Reference Treasury Dealer” means (1) each of Barclays Capital Inc., a Primary
Treasury Dealer (as hereinafter defined) selected by Mitsubishi UFJ Securities (USA), Inc. and a Primary Treasury Dealer selected by Wells Fargo Securities, LLC, and their respective successors, unless any of them ceases to be a primary U.S.
Government securities dealer in the United States (a “Primary Treasury Dealer”) in which case the Company shall substitute for such Reference Treasury Dealer another Primary Treasury Dealer; and (2) any other Primary Treasury
Dealer selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference
Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Quotation Agent by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding that redemption date. 
 In case an event of default, as defined in the Indenture, shall occur, the principal of all of the Bonds at any such time outstanding under the Indenture may be declared or may become due and payable,
upon the conditions and in the manner and with the effect provided in the Indenture. The Indenture provides that such declaration may in certain events be waived by the holders of a majority in principal amount of the Bonds outstanding. 

This Bond is transferable by the registered owner hereof, in person or by duly authorized attorney, on the books of the Company to be
kept for that purpose at the agency of the Company in the City of Chicago, Illinois, and at the agency of the Company in the Borough of Manhattan, The City of New York, upon surrender and cancellation of this Bond and on presentation of a duly
executed written instrument of transfer, and thereupon a new registered Bond or Bonds of the same series, of the same aggregate principal amount and in authorized denominations will be issued to the transferee or transferees in exchange herefor; and
this Bond, with or without others of like form and series, may in like manner be exchanged for one or more new registered Bonds of the same series of other authorized denominations but of the same aggregate principal amount; all upon payment of the
charges and subject to the terms and conditions set forth in the Indenture. 

  
 14 

 The Company or a successor entity may deliver to the Trustee in substitution for any Bonds
of the 2042 Series, mortgage bonds or other similar instruments as set forth in the Indenture. 
 Subject to the preceding
sentence, no recourse shall be had for the payment of the principal of or premium, if any, or interest on this Bond, or for any claim based hereon or on the Indenture or any indenture supplemental thereto, against any incorporator, or against any
stockholder, director or officer, past, present or future, of the Company, or of any predecessor or successor corporation, as such, either directly or through the Company or any such predecessor or successor corporation, whether by virtue of any
constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stockholders, directors or
officers being released by every owner hereof by the acceptance of this Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Indenture. 

No director, officer, employee or stockholder of the Company will have any liability for any obligations of the Company under the Bonds
or Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder by accepting a Bond waives and releases all such liability. The waiver and release are part of the consideration for issuance of
the Bonds. The waiver may not be effective to waive liabilities under the federal securities laws. It is the view of the Securities and Exchange Commission that this type of waiver is against public policy. 

This Bond shall not be entitled to any benefit under the Indenture or any indenture supplemental thereto, or become valid or obligatory
for any purpose, until The Bank of New York Mellon Trust Company, N.A., the Trustee (as successor to Harris Trust and Savings Bank) under the Indenture, or a successor trustee thereto under the Indenture, shall have signed the form of certificate
endorsed hereon.

interest charges described in such provisions, instead of two and one-half times such charges, but shall not otherwise affect such provisions or relieve from the requirements therein pertaining to ten percent (10%) of the principal amount of
Bonds therein described.
