			3.

				
			Compensation.

5.     Termination of Employment.

 

	 	
			a.

				
			Termination Without Cause. Provided that not less than six (6) months have elapsed since the effective date of this Agreement, if Executive’s employment is thereafter terminated by the Company (other than for Cause), Executive will be entitled to all accrued and unpaid Base Salary, accrued prior year bonuses and other accrued benefits and expense reimbursements through the date of termination, plus he will be entitled to receive the following severance benefits:

			

 

	 	
			(i)

				
			Executive will be entitled to receive a severance amount equal to his then current Base Salary for a period of nine (9) months from the date of termination, plus a bonus equal to the greater of (a) Executive’s most recent Discretionary Bonus or (b) three (3) months of Base Salary, both to be paid within five (5) business days from the date of termination; and

			

 

	 	
			(ii)

				
			Company will provide Executive with the same or similar health care benefits (including life, dental, and vision, if any) as provided to Executive at the time of termination, such health care benefits to be provided for a period of six (6) months from the date of termination; and

			

 

	 	
			(iii)

				
			All non-vested equity awards granted to Executive will immediately vest and will be exercisable for a period of three months following such termination in accordance with the Company’s 2016 Stock Incentive Plan or any similar plan as the Company may adopt from time to time which such equity award was granted under.

			

 

For purposes of this Agreement: (i) any material reduction in the Executive’s responsibilities, duties, title or compensation of the Executive without the Executive’s written consent or (ii) if the Company gives notice to the Executive that it will not renew this Agreement pursuant to Section 2 hereof, shall be deemed an Effective Termination Without Cause.

 

Upon termination of Executive’s employment without cause or upon the Executive’s resignation as a result of an Effective Termination Without Cause, except for the obligations set forth in this subsection 5a., the obligations of the Company to make any further payments or to provide any further benefits to Executive under this Agreement will cease and terminate.

 

If the independent members of the Board of Directors unanimously determine, at their sole election, that the Executive has materially not met his obligations as set forth in Section 1 above, but not to the full extent required to trigger termination for Cause as defined in subsection 5d., then termination of the Executive will be deemed to be a resignation and governed under the terms of subsection 5b.

 

	 	
			b.

				
			Termination by Resignation. If Executive resigns other than due to an Effective Termination Without Cause, Executive will be entitled to receive only accrued but unpaid Base Salary, accrued unpaid prior year bonuses and accrued benefits (including vested equity awards) through the effective date of Executive’s resignation.

			

 

Upon termination of Executive’s employment by resignation, the obligations of the Company under this Agreement to make any further payments or to provide any further benefits to Executive will cease and terminate.

 

	 	
			c.

				
			Termination Following a Change of Control Event.

			

 

	 	
			(i)

				
			For purposes of this Agreement, a “Change of Control Event” shall mean any of the following:

			

 

	 	
			(1)

				
			Any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing more than 40% of the total voting power represented by the Company’s then outstanding voting securities; or

			

 

	 	
			(2)

				
			A merger or consolidation of the Company whether or not approved by the Board of Directors of the Company, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least 60% of the total voting power represented by the voting securities of the Company or such surviving entity (or the parent of any such surviving entity) outstanding immediately after such merger or consolidation, or a change in the ownership of all or substantially all of Company’s assets to a person not related (within the meaning of income tax Regulations Section 1.409A-3(i)(5)(vii)(b)) to the Company; or

			

 

	 	
			(3)

				
			The replacement during any 12-month period of a majority of the members of the Board of Directors of the Company with directors whose appointment or election was not endorsed by a majority of the members before the date of the appointment or election.

			Immediately upon the occurrence of a Change of Control Event, all non-vested equity awards granted to Executive will immediately vest and be exercisable for the longer of three months following the date of such Change of Control Event or (if longer) the period set forth for the exercise of any such options held by any employee in the agreement accomplishing the Change of Control Event.

			

 

	 	
			(iii)

				
			If Executive’s employment is terminated by the Company or Executive resigns due to an Effective Termination Without Cause (in either case, within twelve (12) months following a Change of Control Event), Executive will be entitled to all accrued and unpaid Base Salary, accrued prior year bonuses and other accrued benefits through the date of termination, plus he will be entitled to receive the following severance benefits:

			

 

	 	
			(1)

				
			Executive will be entitled to receive: (i) six (6) months of his then current Base Salary; plus (ii) 100% of the target amount of any Discretionary Bonus which Executive is eligible to earn in the present year. All such amounts shall be paid within five (5) days from the date of termination.

			

 

	 	
			(2)

				
			Executive will be entitled to receive the benefits described in subsection 5(a)(ii) above; and

			

 

Upon termination of Executive’s employment resulting from a Change of Control Event, except for the obligations set forth in this subsection c., the obligations of the Company under this Agreement to make any further payments or to provide any further benefits to Executive will cease and terminate.

Upon termination of Executive’s employment by Permanent Disability, except as set forth in this subsection e., the obligations of the Company to make any further payments or to provide any further benefits to Executive will cease and terminate.

			Nondisclosure of Confidential Information. During Executive’s employment, and for a period of two years thereafter, Executive will not, without the prior written consent of the Board of Directors, use, divulge, disclose or make accessible to any other person, firm, partnership, corporation or other entity any Confidential Information pertaining to the business of the Company or any of its affiliates, except (a) while employed by the Company, in the business of and for the benefit of the Company, or (b) as required by law. “Confidential Information” includes without limitation non-public information concerning the financial data, business plans, product development (or other proprietary product data), customer lists, marketing, acquisition and divestiture plans and other non-public, proprietary and confidential information of the Company. Executive or his legal representatives, heirs or designated beneficiaries must return all Confidential Information within 15 days of the termination of Executive’s employment for any reason. Executive acknowledges that this Section 6 survives the termination of Executive’s employment and is enforceable by the Company at any time, regardless of whether the Executive continues to be employed by the Company.

			

 

7.     Non-Competition and Non-Solicitation

 

	 	
			a.

				
			From the date hereof through the Term or, in the event Executive’s employment is terminated, from the date hereof through the first anniversary of Executive’s termination of employment with the Company, Executive agrees that, without the prior written consent of the Board of Directors, he will not (i) engage in or have any direct interest in, as an employee, officer, director, agent, subcontractor, consultant, security holder, partner, creditor or otherwise, any business in competition with the Company other than as a 10% or less equity stakeholder; (ii) cause or attempt to cause any person who is, or was at any time during the six months immediately preceding the termination of Executive, an employee of the Company to leave the employment of the Company; or (iii) solicit, divert or take away, or attempt to take away, the business or patronage of any client, customer or account, or prospective client, customer or account, of the Company.

			

 

	 	
			b.

				
			For purposes of this Section 7, a business will be deemed to be in competition with the Company if it is in the business of providing services to oil and/or gas production companies similar to those provided by the Company in the states in which the Company operates at the time of Executive’s termination.

			

 

	 	
			c.

				
			Executive acknowledges that this Section 7 survives the termination of Executive’s employment and is enforceable by the Company at any time, regardless of whether the Executive continues to be employed by the Company.

			

 

	 	
			d.

				
			Executive and the Company agree that this covenant not to compete is a reasonable covenant under the circumstances with respect to both scope and duration, and further agree that if in the opinion of any court of competent jurisdiction such restraint is not reasonable in any respect, such court will have the right, power and authority to excise or modify such provision or provisions of this covenant as to the court will appear not reasonable and to enforce the remainder of the covenant as so amended.

			

 

	 	
			e.

				
			Executive agrees that any breach of the covenants contained in this Section 7 would irreparably injure the Company. Accordingly, Executive agrees that the Company may, in addition to pursuing any other remedies it may have in equity, obtain an injunction against Executive from any court having jurisdiction over the matter restraining any further violation of this Agreement by Executive and cease making any payments otherwise required by this Agreement.

			

 

	
			8.

				
			Ownership of Intellectual Property. Executive acknowledges and agrees that all intellectual property created, acquired, adapted, modified or improved, in whole or in part, by or through the efforts of Executive during the course of his employment by the Company, including without limitation all copyrights, patents, trademarks, service marks, trade secrets, know-how or other work product in any way related to the Company’s operations and activities, are works for hire and are owned exclusively by the Company, and Executive hereby disclaims any right or interest in or to any such intellectual property.

			

 

3

 

 

	
			9.

				
			Property of the Company. Upon any termination of Executive’s employment, Executive agrees to return to the Company any and all records, files, notes, memoranda, reports, work product and similar items, and any manuals, drawings, sketches, plans, tape recordings, computer programs, disks, cassettes, and other physical representations of any information, relating to the Company, or any of its affiliates, whether or not constituting Confidential Information. Executive also agrees to return to the Company any other property belonging to the Company, including but not limited to any laptop computer, no later than the date of Executive’s termination from employment for any reason. Executive acknowledges and agrees that retaining any copies of Confidential Information will be deemed to be the misappropriation of the property of the Company.

			

 

	
			10.

				
			Section 280G Safe Harbor Cap. If it shall be determined that any payment or distribution or any part thereof of any type to or for the benefit of Executive whether pursuant to this Agreement or any other agreement between Executive and the Company, or any person or entity that acquires ownership or effective control of the Company, or ownership of a substantial portion of the Company’s assets (within the meaning of Section 280G of the Code) whether paid or payable or distributed or distributable pursuant to the terms of the Agreement or any other agreement, (the “Total Payments”), is or will be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Total Payments shall be reduced to the maximum amount that could be paid to Executive without giving rise to the Excise Tax (the “Safe Harbor Cap”), if the net after-tax payment to Executive after reducing Executive’s Total Payments to the Safe Harbor Cap is greater than the net after-tax (including the Excise Tax) payment to Executive without such reduction.

			

 

The reduction of the amounts payable hereunder, if applicable, shall be made by reducing payments that trigger the excise tax, and such reductions will be first the payment made pursuant to the Agreement and then to payments pursuant to any other agreements that are not subject to Section 409A of the Code, and finally to payments pursuant to any other agreements that are subject to Section 409A of the Code, provided that Executive shall have no ability to designate the order of such reductions. All mathematical determinations, and all determinations as to whether any of the Total Payments are “parachute payments” (within the meaning of Section 280G of the Code), that are required to be made under this Section 10, including determinations as to whether the Total Payments to Executive shall be reduced to the Safe Harbor Cap and the assumptions to be utilized in arriving at such determinations, shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”).

 

If the Accounting Firm determines that the Total Payments to Executive shall be reduced to the Safe Harbor Cap (the “Cutback Payment”) and it is established pursuant to a final determination of a court or an Internal Revenue Service (the “IRS”) proceeding which has been finally and conclusively resolved, that the Cutback Payment is in excess of the limitations provided in this Section 10 (such excess amount hereinafter referred to as an “Excess Payment”), such Excess Payment shall be deemed for all purposes to be an overpayment to Executive made on the date such Executive received the Excess Payment. The Company or Executive, as applicable, shall notify the other within 30 days of its receipt of such final determination of the amount of the Excess Payment, along with a copy of the final determination, and Executive shall repay the Excess Payment amount to the Company within 30 days of such notification; provided, however, if Executive shall be required to pay an Excise Tax by reason of receiving such Excess Payment (regardless of the obligation to repay the Company), Executive shall provide the Company with written evidence of such requirement to pay an Excise Tax amount, and shall then be required to repay the Excess Payment reduced by such Excise Tax amount (or if already paid by Executive, the Company shall reimburse Executive within 10 days of proof of payment).

 

	
			11.

				
			Repayment Provisions. If the Company is required to prepare an accounting restatement due to noncompliance with any financial reporting requirement under United States securities laws for any filings made during the Term, commencing with the first full quarter following the date of this Agreement, then Company will have the right to require Executive to reimburse the Company for (a) any bonus or other incentive-based or equity-based compensation received by Executive from the Company during the 12-month period following the first public issuance or filing with the Securities and Exchange Commission (whichever first occurs) of the financial documents embodying such financial reporting requirement, (b) any profits realized by the Executive from the sale of securities of the Company during such 12-month period and (c) such other incentive-based compensation as may be specified by applicable law, regulation or listing standard.

			12.

				
			Miscellaneous.

			

 

	 	
			a.

				
			All notices and other communications required or to be given under this Agreement will be in writing and given either (i) by personal delivery against a receipted copy, (ii) by certified or registered United States mail, return receipt requested, postage prepaid, (iii) by facsimile, or (iv) by attachment to electronic mail in PDF or similar file format. Notice to the Company shall be sent to the address of the Company’s principal offices, and notice to Executive shall be sent to the address on file for Executive in the Company’s records, or such other addresses and numbers as a party hereto may provide in accordance with this subsection a. Notice will be deemed delivered when received if by personal delivery; three days after placement with the United States Postal Service if mailed; upon receipt of a confirmation that the transmission has been successfully sent if by facsimile; and when sent if sent by electronic mail.

			

 

	 	
			b.

				
			This Agreement, along with any amendments from time to time made hereto, constitutes the full, entire and integrated agreement between the parties hereto with respect to the subject matter hereof.

			

 

	 	
			c.

				
			Executive represents and warrants to the Company that Executive is free to enter into this Agreement and has no contract, commitment, arrangement or understanding to or with any party that restrains or is in conflict with Executive’s performance of the covenants, services and duties provided for in this Agreement. Executive agrees to indemnify the Company and to hold it harmless against any and all liabilities or claims arising out of any unauthorized act or acts by Executive that, the foregoing representation and warranty to the contrary notwithstanding, are in violation, or constitute a breach, of any such contract, commitment, arrangement or understanding. Executive further represents and warrants to the Company that Executive has consulted with his legal, tax, accounting, and investment advisors with respect to the advisability of entering into this Agreement to the extent that Executive has determined such consultation to be necessary or appropriate.

			

 

	 	
			d.

				
			This Agreement will be binding upon and inure to the benefit of the heirs and representatives of Executive and the assigns and successors of the Company, but neither this Agreement nor any rights or obligations hereunder will be assignable by Executive (except by will or by operation of the laws of intestate succession) or by the Company, except that the Company may assign this Agreement to any successor (whether by merger, purchase or otherwise) to all or substantially all of the stock, assets or businesses of the Company, if such successor expressly agrees to assume the obligations of the Company hereunder.

			

 

	 	
			e.

				
			Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any clause or provision of this Agreement is held illegal, invalid or unenforceable then it is the intention of the parties hereto that the remainder of this Agreement will not be affected thereby. It is also the intention of the parties to this Agreement that in lieu of each clause or provision of this Agreement that is illegal, invalid or unenforceable, there be added, as a part of this Agreement, a clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be legal, valid and enforceable.

			

 

	 	
			f.

				
			The respective rights and obligations of the parties hereunder will survive any termination of this Agreement to the extent necessary to the intended preservation of such rights and obligations. The provisions of this subsection f. are in addition to the survivorship provisions of any other section of this Agreement.

			

 

	 	
			g.

				
			No provision of this Agreement may be amended, waived or otherwise modified without the prior written consent of all the parties hereto.

			

 

	 	
			h.

				
			The waiver by any party hereto of a breach of any provision or condition contained in this Agreement will not operate or be construed as a waiver of any subsequent breach or of any other conditions hereof.

			

 

	 	
			i.

				
			This Agreement may be executed in any number of counterparts, each of which will be deemed to be an original and all of which together will be deemed to be one and the same instrument.

			

 

	 	
			j.

				
			This Agreement was made in the state of Colorado, and will be governed by, construed, interpreted and enforced in accordance with the laws of the state of Colorado.

 AMEREN ILLINOIS COMPANY, a corporation organized and existing under the laws of the
State of Illinois (the “Company”), which term shall include any Successor Corporation as defined in the Indenture hereinafter referred to, for value received, hereby promises to pay to _____________________________, or registered
assigns, the principal sum of _____________ ($______) on the Maturity Date set forth above in any coin or currency of the United States of America, which at the time of payment is legal tender for public and private debts, and to pay interest
thereon from and including the Original Issue Date specified above or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually in arrears on May 15 and November 15 of each
year, commencing on November 15, 2018, and on the Maturity Date, at the per annum Interest Rate set forth above until the principal hereof is paid or made available for payment. No interest shall accrue on the Maturity Date, so long as the
principal amount of this Bond is paid on the Maturity Date. The interest so payable, and punctually paid or duly provided for, on any such Interest Payment Date (except for interest payable on the Maturity Date set forth above or, if applicable,
upon acceleration), will, as provided in the Indenture hereinafter referred to, be paid to the Person in whose name this Bond is registered at the close of business on the Regular Record Date for such interest, which shall be the May 1 or
November 1, as the case may be, whether or not a Business Day, next preceding such Interest Payment Date; provided, that the first Interest Payment Date for any part of this Bond, the Original Issue Date of which is after a Regular Record Date
but prior to the applicable Interest Payment Date, shall be the Interest Payment Date following the next succeeding Regular Record Date; and provided further, that interest payable on the Maturity Date set forth above or, if applicable, upon
acceleration, shall be payable to the Person to whom principal shall be payable. Except as otherwise provided in the Indenture, any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such
Regular Record Date and shall be paid to the Person in whose name this Bond is registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee, notice whereof shall be given to
Holders not more than fifteen days nor fewer than ten days prior to such Special Record Date. 
 This Bond is one of a duly authorized issue
of Bonds of the Company (the “Bonds”) in unlimited aggregate principal amount except as provided in the Indenture, of the series hereinafter specified, all issued and to be issued under and equally secured by the General Mortgage
Indenture and Deed of Trust (as amended and supplemented, the “Indenture”), dated as of November 1, 1992, executed by the Company (as successor to Illinois Power Company) to The Bank of New York Mellon Trust Company, N.A., as
successor trustee to Harris Trust and Savings Bank (the “Trustee”), to which Indenture reference is hereby made for a description of the properties mortgaged and pledged, the nature and extent of the security, the rights of
registered owners of the Bonds and of the Trustee in respect thereof, 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 

  
 5 

 
may otherwise vary as provided in the Indenture. This Bond is one of a series designated as the Bonds of the 2028 Series of the Company, unlimited in aggregate principal amount except as
provided in the Indenture, issued under and secured by the Indenture and described in the Supplemental Indenture dated as of May 1, 2018 (the “Supplemental Indenture of May 1, 2018”), between the Company and
the Trustee, supplemental to the Indenture. 
 Each Bond of this Series shall be dated and issued as of the date of its authentication by
the Trustee and shall bear an Original Issue Date. Each Bond of this Series issued upon transfer, exchange or substitution of such Bond shall bear the Original Issue Date of such transferred, exchanged or substituted Bond, as the case may be. 

The Bonds of this Series shall be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. 

Interest on this Bond will accrue from and including the Original Issue Date specified above to, but excluding, November 15, 2018, and
thereafter, from and including each Interest Payment Date to, but excluding, the next succeeding Interest Payment Date, the Maturity Date or any redemption date, as the case may be. 

All or a portion of the Bonds of this Series may be redeemed at the option of the Company at any time or from time to time. The redemption
price for the Bonds of this Series to be redeemed on any redemption date prior to February 15, 2028 (three months prior to the Maturity Date) (the “Par Call Date”) will be equal to the greater of the following amounts:
(a) 100% of the principal amount of the Bonds of this Series being redeemed on that redemption date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Bonds of this Series being
redeemed on that redemption date that would be payable if such Bonds matured on the Par Call Date (not including any portion of any payments of interest accrued to the redemption date), discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined below) plus 15 basis points, as determined by the Reference
Treasury Dealer (as defined below), plus, in each case, accrued and unpaid interest thereon to the redemption date. The redemption price for the Bonds of this Series to be redeemed on any redemption date on or after the Par Call Date will be equal
to 100% of the principal amount of the Bonds of this Series being redeemed on that redemption date plus accrued and unpaid interest thereon to the redemption date. 

The redemption price shall be payable to the Person to whom principal shall be payable except that installments of interest on Bonds of this
Series that are due and payable on Interest Payment Dates falling on or prior to a redemption date will be payable on the Interest Payment Date to the Holder of this Bond as of the close of business on the relevant Regular Record Date pursuant to
the Indenture. 
 With respect to a redemption occurring prior to the Par Call Date the Company shall give the Trustee written notice of the
redemption price promptly after the calculation thereof and the Trustee shall not be responsible for such calculation. 
 The Company shall
mail notice of any redemption at least 10 days but not more than 60 days before the redemption date to each Holder of the Bonds of this Series to be redeemed, and, if less than all Bonds of this Series are to be redeemed, the particular Bonds
of this Series to be redeemed will be selected by the Trustee in such manner as it shall deem appropriate and fair; provided, that as long as the Bonds of this Series are represented by global certificates registered in the name of The Depository
Trust Company (“DTC”), or its nominee, beneficial interests in such global certificates will be selected for redemption by DTC in accordance with its standard procedures therefor. 

Any notice of redemption at the Company’s option may state that such redemption will be conditional upon receipt by the Trustee, on or
prior to the date fixed for such redemption, of money sufficient to pay the principal of, premium, if any, and interest on, the Bonds of this Series or portions thereof called for redemption, and that if such money has not been so received, such
notice will be of no force and effect and the Company will not be required to redeem such Bonds or portions thereof. Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on
the Bonds of this Series or portions thereof called for redemption. 

  
 6 

 “Adjusted Treasury Rate” means, with respect to any redemption date, the rate
per annum equal to the semiannual 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 such
redemption date. 
 “Business Day” means, with respect to Bonds of this series, any weekday that is not a day on which
banking institutions or trust companies in the Borough of Manhattan, the City and State of New York, or in the city where the corporate trust office of the Trustee is located, are obligated or authorized by law or executive order to close. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as having a
maturity comparable to the remaining term of the Bonds of this Series to be redeemed (assuming, for this purpose, that the Bonds of this Series matured on the Par Call Date that would be utilized, 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 such Bonds of this Series. 

“Comparable Treasury Price” means, with respect to any redemption date, (A) the average of the Reference Treasury Dealer
Quotations for such redemption date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (B) if the Company obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such
quotations, or (C) if only one Reference Treasury Dealer Quotation is received, such quotation. 
 “Reference Treasury
Dealer” means each of (A) J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC and a Primary Treasury Dealer (as defined below) selected by U.S. Bancorp Investments, Inc., or, in each case, an
affiliate thereof, which are primary U.S. Government securities dealers in the United States (each, a “Primary Treasury Dealer”), and their respective successors; provided, however, that if any of the foregoing shall cease to be a
Primary Treasury Dealer, the Company will substitute therefor another Primary Treasury Dealer; and (B) any other Primary Treasury Dealer(s) 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 Company, 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 Company by such Reference Treasury Dealer at 5:00 p.m.
(New York City time) on the third Business Day preceding such redemption date. 
 Interest payments for this Bond shall be computed and paid
on the basis of a 360-day year consisting of twelve 30-day months (and for any partial periods shall be calculated on the basis of the number of days elapsed in a 360-day year of twelve 30 day months). If any Interest Payment Date falls on a day that is not a Business Day, the interest due on such Interest Payment Date will be paid on the next succeeding Business Day (and
without any interest or other payment in respect of any such delay). If the Maturity Date of this Bond or any redemption date falls on a day that is not a Business Day, the payment of principal, premium, if any, and interest will be made on the next
succeeding Business Day with the same force and effect as if made on such Maturity Date or redemption date, and no interest on such payment shall accrue for the period from and after the Maturity Date or such redemption date. 

The Company, at its option, and subject to the terms and conditions provided in the Indenture, will be discharged from any and all obligations
in respect of the Bonds of this Series (except for certain obligations including obligations to register the transfer or exchange of Bonds of this Series, replace stolen, lost or mutilated Bonds of this Series, maintain paying agencies and hold
monies for payment in trust, all as set forth in the Indenture) if the Company deposits with the Trustee money, Government Obligations which through the payment of interest thereon and principal thereof in accordance with their terms will provide
money, or a combination of money and Government Obligations, in any event in an amount sufficient, without reinvestment, to pay all the principal of and any premium and interest on the Bonds of this Series on the dates such payments are due in
accordance with the terms of the Bonds of this Series. 

  
 7 

 In case an Event of Default, as defined in the Indenture, shall occur and be continuing, the
principal of all 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 be rescinded under certain circumstances. 
 The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modifications of the rights and obligations of the Company and the rights of the Holders under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal
amount of the outstanding Bonds of all series directly affected by such amendment or modifications, considered as one class. Each initial and future Holder of this Bond, by its acquisition of an interest in this Bond, irrevocably (a) consents
to the amendments set forth in Article I of the Supplemental Indenture dated as of October 25, 2017, supplemental to the Indenture, without any other or further action by any Holder of this Bond, and (b) designates the Trustee, and its
successors, as its proxy with irrevocable instructions to vote and deliver written consents on behalf of such Holder in favor of such amendments at any meeting of Holders, in lieu of any meeting of Holders, in any consent solicitation or otherwise.
Any such consent or waiver by the Holder of this Bond shall be conclusive and binding upon such Holder and upon all future Holders of this Bond and of any Bond issued upon the registration of transfer hereof or in exchange therefor or in lieu
thereof whether or not notation of such consent or waiver is made upon this Bond. 
 As set forth in and subject to the provisions of the
Indenture, no Holder of any Bonds will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder unless such Holder shall have previously given to the Trustee written notice of a continuing Event of
Default with respect to such Bonds, the Holders of a majority in aggregate principal amount of the outstanding Bonds shall have made written request and offered reasonable indemnity to the Trustee to institute such proceeding as Trustee and the
Trustee shall have failed to institute such proceeding within 60 days after its receipt of such notice; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal
of and any premium or interest on this Bond on or after the respective due dates expressed herein. 
 No reference herein to the Indenture
and to provisions of this Bond or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Bond at the times, places and rates and the
coin or currency prescribed in the Indenture. 
 As provided in the Indenture and subject to certain limitations therein set forth, this
Bond may be transferred only as permitted by the legend hereto and the provisions of the Indenture. 
 This Bond shall be governed by and
construed in accordance with the laws of the State of Illinois, except to the extent that the law of any other jurisdiction shall be mandatorily applicable. 

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 form of certificate endorsed hereon shall have been signed by or on behalf of The Bank of New York Mellon Trust Company, N.A., as successor trustee to Harris Trust and Savings Bank, the Trustee under the Indenture, or a
