EAGLE MATERIALS INC. 

CEMENT COMPANIES 

SALARIED INCENTIVE COMPENSATION PROGRAM 

FOR FISCAL YEAR 2017 
  

	1.	Purpose 

 The purpose of the Eagle Materials Inc. Cement Companies Salaried
Incentive Compensation Program for Fiscal Year 2017 (the “Plan”) is to establish an incentive bonus program which: (i) focuses on the performance of each Cement company subsidiary as well as individual performance; and (ii) aligns the
interest of participants with those of the shareholders of Eagle Materials Inc. (“Eagle”). The Plan is adopted by the Compensation Committee of the Board of Directors (the “Committee”) under the structure of Eagle Materials Inc.
Amended and Restated Incentive Plan (the “Incentive Plan”) and is subject to all the terms and conditions of such Incentive Plan, including, without limitation the limits set forth in Section 8 of the Incentive Plan. The Plan shall be
in effect for the fiscal year ending March 31, 2017. 
  

	2.	Bonus Pool 

 To insure reasonableness and affordability the available funds for
bonus payments are determined as a percent of operating earnings of each of the cement companies of Eagle Materials Inc. The actual percentage may vary from year to year. For Fiscal Year 2017, the bonus pool for each subsidiary cement company will
be equal to 2.25% of each Cement company’s operating earnings; provided, however, that for Fiscal Year 2017, the Sugar Creek Plant shall have an additional bonus pool equal to 0.40% of the Sugar Creek Plant’s operating earnings to help
transition additional employees into that pool. 
 Participants must be employed at fiscal year-end to be eligible for any bonus
award. Awards may be adjusted for partial year participation for participants added during a year. The Committee hereby delegates to the CEO of Eagle all its duties and authorities to grant awards under the Plan except that the Committee
shall retain all authority with respect to awards to the Eagle EVP-Cement. 
  

	3.	Eligibility 

 The Eagle EVP-Cement, the subsidiary cement company Presidents, and
his/her direct reports will be participants in the Plan. Additional participants who have management responsibilities or are in a professional capacity that can measurably impact earnings may be recommended by subsidiary cement company Presidents,
subject to the approval of the Eagle EVP-Cement and the Eagle CEO. The addition of new participants will not affect the total pool available but will in effect dilute the potential bonuses of the original participants. 

A participant must be an exempt salaried manager or professional. No hourly or non-exempt employee may participate. Participants in this
plan may not participate in any other company incentive plan with monetary awards, except for the Cement Companies Long-Term Compensation Program, the Eagle Materials Long-Term Compensation Program and the Eagle Materials Special Situation Program.

	4.	Allocation of Pool 

 The Eagle EVP-Cement will be eligible for a percentage of the
total of all subsidiary cement pools which percentage shall be recommended by the CEO and shall be approved by the Committee. The subsidiary cement company Presidents will be eligible to receive a percentage of the pool funded from their respective
subsidiary company, which percentage shall be recommended by the Eagle EVP-Cement and approved by the Eagle CEO. The subsidiary cement company Presidents will recommend the distribution of the remainder of their subsidiary company pool. For each
participant in the Plan, the maximum annual bonus award opportunity is represented by the percentage of the applicable pool assigned to such participant. The participants in the Plan and their percentage of the pool will require approval of the
Eagle EVP-Cement and Eagle Materials CEO (except for the Eagle EVP-Cement and his percentage which shall be approved by the Committee) at the beginning of the fiscal year for which the bonus is being earned.

The subsidiary cement company President’s bonus opportunity shall be 50% goal based, 10% budget based and 40% discretionary taking into
consideration overall job performance and compliance with Eagle Materials Policies and Code of Ethics. All participants in the Plan must have the ability to significantly affect the performance of the subsidiary company by achieving measurable,
quantifiable, objectives. The subsidiary cement company Presidents will determine the objective and discretionary balance of bonus opportunities for the other participants in their companies, subject to approval by the Eagle EVP-Cement and Eagle
Materials CEO. 
  

	5.	Objective Criteria 

 At the beginning of the fiscal year goals and objectives
shall be established for each participant. Objectives should be measurable and focus on areas that have meaningful impact on our operational performance.
  

	6.	Measuring Performance 

 At the close of the fiscal year: (i) each subsidiary
cement company President will review the overall performance of each participant in such subsidiary and each such participant’s achievement of the goals and objectives submitted at the beginning of the year and recommend to the Eagle EVP-Cement
distribution of the bonus pool to the participants; and (ii) the Eagle CEO will review the performance of the Eagle EVP-Cement versus the objectives submitted at the beginning of the year and recommend to the Committee a distribution to the Eagle
EVP-Cement. Distribution of the bonus pool to all participants, other than the Eagle EVP-Cement, requires approval of both the Eagle EVP-Cement and the Eagle CEO. Distributions to the Eagle EVP-Cement requires the recommendation of the
Eagle CEO and the approval of the Committee. 
 Any portion of the Company Operating Pool not paid out (unearned) or forfeited will be
added to the Special Situation Program (the “SSP”) at Corporate. 

  
 - 2 - 

	7.	No Employment Guaranteed 

 No provision of this Plan hereunder shall confer any
right upon any participant to continued employment. 
  

	8.	Governing Law 

 This Plan and all determinations made and actions taken pursuant
hereto, shall be governed by and construed in accordance with the laws of the State of Texas, without reference to any conflicts of law principles thereof that would require the application of the laws of another jurisdiction.

EAGLE MATERIALS INC. 

SPECIAL SITUATION PROGRAM 

FOR FISCAL YEAR 2017 
 1.
The Eagle Materials Inc. Special Situation Program for Fiscal Year 2017 (the “SSP” or the “Plan”) shall be funded by: (i) 0.35% of Eagle Material Inc.’s operating earnings, as determined by the
Compensation Committee of the Board of Directors (“Committee”); (ii) the portions of subsidiary company and corporate annual incentive compensation bonus pools not paid out (not earned); and (iii) the portion of the subsidiary companies
long-term compensation plans not paid out (not earned). All full-time employees of Eagle Materials Inc. (“Eagle” or the “Company”) or a subsidiary company will be eligible to receive an SSP award. 

 

	 	A.	An SSP award is intended to recognize outstanding individual performances during the current fiscal year based on contributions that dramatically improve the Company’s profitability or worth.

  

	 	B.	An SSP award may also be made to individuals at Eagle or at subsidiary companies whose operating profit has been adversely affected by market conditions in order to recognize superior performance of the participants
at those companies. 

  

	 	C.	SSP funds not awarded may be retained by the Company for use in future fiscal years. 

2. SSP awards may be recommended by subsidiary company Presidents, Eagle EVP’s and/or the Eagle Chief Executive Officer
(“CEO”). The approval of the Eagle CEO is required for all SSP awards; provided, that an SSP award to any senior executive officers who are required to make disclosures under Section 16 of the Securities Exchange Act of 1934, as amended
(“Executive Officers”), shall require the approval of the Committee. 
 3. The SSP shall be administered by the CEO, who shall
have full and exclusive power to interpret the Plan and to adopt such rules, regulations and guidelines for carrying out this Plan as the CEO may deem necessary or appropriate in the CEO’s sole discretion. All decisions of the CEO shall be
binding and conclusive on the participants. Notwithstanding the foregoing, any matter affecting an SSP award to an Executive Officer (including, without limitation, any interpretation of the Plan or the adoption of any rules, regulations or
guidelines affecting an award to an Executive Officer) shall be approved by the Committee. Any decision by the Committee with respect to an Executive Officer shall be final and binding. 

4. This Plan and all determinations made and actions taken pursuant hereto, shall be governed by and construed in accordance with the laws of
the State of Texas, without reference to any conflicts of law principles thereof that would require the application of the laws of another jurisdiction.EX-4.1

days prior to such arrangement (except for leases of three years or less), whereby such property has been or is to be sold or transferred by the Issuer or any Subsidiary of the Issuer to such Person (herein referred to as a “Sale and Lease-Back
Transaction”), unless: 
 (a) the Issuer or such Subsidiary would, at the time of entering into a Sale and Lease-Back
Transaction, be entitled to incur Indebtedness secured by a mortgage on such Principal Property to be leased in an amount at least equal to the Attributable Debt in respect of such transaction without equally and ratably securing the Notes pursuant
to Section 4.09 hereof; or 
 (b) the Issuer shall covenant that it will apply an amount equal to the net proceeds from
the sale of the Principal Property so leased to the retirement (other than any mandatory retirement) of its Funded Indebtedness within 90 days of the effective date of any such Sale and Lease-Back Transaction, provided that the amount to be
applied to the retirement of Funded Indebtedness of the Issuer shall be reduced by (i) the principal amount of any Notes delivered by the Issuer to the Trustee within 90 days after such Sale and Lease-Back Transaction for retirement and
cancellation, and (ii) the principal amount of Funded Indebtedness, other than Notes, voluntarily retired by the Issuer within 90 days following such Sale and Lease-Back Transaction, and provided, further, that the covenant contained in
this Section 4.10 shall not apply to, and there shall be excluded from Attributable Debt in any computation under this Section 4.10, Attributable Debt with respect to any Sale and Lease-Back Transaction if: 

(A) such Sale and Lease-Back Transaction is entered into in connection with transactions which are part of an industrial
development or pollution control financing, or 
 (B) the only parties involved in such Sale and Lease-Back Transaction are
the Issuer and any Subsidiary or Subsidiaries of the Issuer. 
 Notwithstanding these restrictions on Sale and Lease-Back
Transactions, the Issuer and its Subsidiaries may enter into, create, assume and suffer to exist Sale and Lease-Back Transactions, not otherwise permitted hereby, if at the time of, and after giving effect to, such Sale and Lease-Back Transactions,
the total consolidated Attributable Debt of the Issuer and its Subsidiaries in respect of such Sale and Lease-Back Transactions, together with mortgages incurred pursuant to Section 4.09(y) hereof, does not exceed 10% of Consolidated Net
Tangible Assets of the Issuer.”

Original Indenture, the following shall be an “Event of Default” with respect to the Notes: 
 (a) Either
(i) default by the Issuer, the Guarantor or any Subsidiary of the Issuer in the payment at the Stated Maturity, after the expiration of any applicable grace period, of principal of, or premium, if any, or interest on, any Indebtedness then
Outstanding having a principal amount in excess of $50.0 million or (ii) the acceleration of Indebtedness of the Issuer, any Guarantor or any Subsidiary of the Issuer having a principal amount in excess of $50.0 million by the holders thereof

ADDITIONAL AMENDMENTS TO THE ORIGINAL INDENTURE 

Section 7.01 Amendment to Section 11.02(b). Only in relation to the Notes, the first paragraph of Section 11.02(b) of
the Original Indenture is hereby amended and restated in its entirety to read as follows: 
 “(b) Subject to Sections
11.02(c), 11.03 and 11.07, the Partnership at any time may terminate, with respect to Debt Securities of a particular series, all its obligations under the Debt Securities of such series and this Indenture with respect to the Debt Securities of such
series (“legal defeasance option”) or the operation of (i) Article X; (ii) any covenant made applicable to such Debt Securities pursuant to Section 2.03; (iii) Sections 6.01(d), (g) and (h) (including, without
limitation, all Events of Default added pursuant to Article VI of the Fifth Supplemental Indenture); and (iv) as they relate to the Guarantors only, Sections 6.01(e) and (f) (“covenant defeasance option”). If the Partnership
exercises either its legal defeasance option or its covenant defeasance option with respect to Debt Securities of a particular series that are entitled to the benefit of the Guarantee, the Guarantee will terminate with respect to that series of Debt
Securities. The Partnership may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option.”

 Capitalized terms used herein shall
have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. 
 1. Interest. Boardwalk
Pipelines, LP, a Delaware limited partnership (the “Partnership” or the “Issuer”), promises to pay interest on the principal amount of this Note at 5.95% per annum until maturity. The Issuer shall
pay interest semi-annually on June 1 and December 1 of each such year, or if any such day is not a Business Day, on the next succeeding Business Day (each an “Interest Payment Date”). Interest on the Notes shall
accrue from the most recent date to which interest has been paid or, if no interest has been paid, from May 16, 2016; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a
record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be December 1,
2016. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the same rate, and it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest shall be computed on
the basis of a 360-day year of twelve 30-day months. 
 2. Method of Payment. The Issuer shall pay interest on the Notes (except
Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the May 
  

	2 	 To be included only if the Note is issued in global form.

  
 Exhibit A-2 

 
15 or November 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in
Section 2.17 of the Original Indenture with respect to Defaulted Interest, and the Issuer shall pay principal (and premium, if any) of the Notes upon surrender thereof to the Trustee or a paying agent on or after the Stated Maturity thereof.
The Notes shall be payable as to principal, premium, if any, and interest at the office or agency of the Trustee maintained for such purpose (which initially is 2 North LaSalle Street, Suite 1020, Chicago, Illinois 60602), or, at the option of the
Issuer, payment of interest may be made by check mailed to the Holders at their addresses set forth in the Debt Security Register or by wire transfer to accounts designated by the Holders; provided that payment by wire transfer of immediately
available funds shall be required with respect to principal of, and interest and premium, if any, on each Global Security. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts. 
 3. Paying Agent and Registrar. Initially, The Bank of New York Mellon Trust Company, N.A.,
the Trustee under the Indenture, shall act as paying agent and Registrar. The Issuer may change any paying agent or Registrar without notice to any Holder. The Partnership may act in any such capacity. 

4. Indenture. The Issuer issued the Notes under an Indenture dated as of August 21, 2009 (the “Original
Indenture”), as amended and supplemented by the Fifth Supplemental Indenture, dated as of May 16, 2016 (the “Fifth Supplemental Indenture,” and, together with the Original Indenture the
“Indenture”), each between the Issuer, Boardwalk Pipeline Partners, LP, as guarantor (together with its successors, the “Guarantor”), and the Trustee. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for
a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are the obligation of the Issuer and the
Guarantor, initially in aggregate principal amount of $550 million. The Issuer may issue an unlimited aggregate principal amount of Additional Notes under the Indenture. Any such Additional Notes that are actually issued shall be treated as issued
and outstanding Notes (and as the same series (with identical terms other than with respect to the issue date, issue price and first payment of interest) as the initial Notes for the purposes indicated in Section 3.02 of the Fifth Supplemental
Indenture). 
 5. Optional Redemption. 

(a) At its option, the Issuer at any time prior to March 1, 2026, may choose to redeem all or any portion of the Notes, at
once or from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of such Notes and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted
to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 50 basis points, plus in each case accrued and unpaid interest, if any, to the Redemption Date (subject to the right
of Holders on the relevant record date to receive interest due on the relevant interest payment date). 

  
 Exhibit A-3 

 (b) At its option, the Issuer at any time on or after March 1, 2026, may
choose to redeem all or any portion of the Notes, at once or from time to time, at a redemption price equal to 100% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to the Redemption Date (subject to the right of
Holders on the relevant record date to receive interest due on the relevant interest payment date). 
 For purposes of determining the
redemption price, the following definitions shall apply: 
 “Comparable Treasury Issue” means the U.S. Treasury
security or securities selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Notes to be redeemed 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 a comparable maturity to the remaining term of the notes to be redeemed. 

“Comparable Treasury Price” means, for any Redemption Date, (1) the average of the Reference Treasury Dealer
Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations or (2) if the Issuer obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

 “Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Issuer. 

“Reference Treasury Dealers” means each of Barclays Capital Inc., Deutsche Bank Securities Inc. J.P. Morgan Securities
LLC, or an affiliate or successor of the foregoing, and, at the Issuer’s option, additional Primary Treasury Dealers (as defined below); provided, however, that if any of the foregoing shall cease to be a primary U.S. Government
securities dealer in New York City (a “Primary Treasury Dealer”), the Issuer shall substitute therefor another Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, for each Reference Treasury Dealer and any Redemption Date, the average,
as determined by the Issuer, 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 Issuer by such Reference Treasury Dealer at 3:30 p.m., New York City
time, on the third business day preceding such Redemption Date. 
 “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, calculated using 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. 
 6. Mandatory Redemption. The Issuer shall not be required to make mandatory
redemption or sinking fund payments with respect to the Notes or to repurchase them at the option of the Holders. 
 7. Notice of
Redemption. Notice of redemption shall be mailed by first class mail at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address. Notes in denominations larger
than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder 

  
 Exhibit A-4 

 
are to be redeemed. On and after the Redemption Date interest shall cease to accrue on Notes or portions thereof called for redemption and with respect to which the redemption price has been
paid. 
 8. Denominations, Transfer, Exchange. The Notes are in registered form without coupons in minimum denominations of $2,000
and integral multiples of $1,000 in excess thereof. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents, and the Issuer may require a Holder to pay any taxes or other governmental charges imposed in relation thereto. 

9. Persons Deemed Owners. The registered Holder of a Note shall be treated as its owner for all purposes. 

10. Amendment, Supplement and Waiver. Subject to certain exceptions, the Indenture may be amended or supplemented with the consent of
the Holders of not less than a majority in aggregate principal amount of the then Outstanding Notes, and any existing default or compliance with any provision of the Indenture relating to the Notes may be waived with the consent of the Holders of
not less than a majority in aggregate principal amount of the then Outstanding Notes. Without the consent of any Holder of a Note, the Indenture may be amended or supplemented for any of the purposes set forth in Section 9.01 of the Indenture,
including to provide for the assumption of the Issuer’s obligations to Holders of the Notes in case of a merger or consolidation of the Issuer or sale of all or substantially all of the Issuer’s assets, to add to the covenants of the
Issuer or any Guarantor, to cure any ambiguity or omission or to correct any defect or inconsistency, to permit the qualification of the Indenture under the TIA, to add or release Guarantors pursuant to the terms of the Indenture, to make any change
that does not adversely affect the rights under the Indenture of any Holder of the Notes, to add to, change or eliminate any of the provisions of the Indenture in respect of one or more series of Debt Securities in certain circumstances, to evidence
or provide for the acceptance of appointment under the Indenture of a successor or separate Trustee or to establish the form or terms of any other series of Debt Securities. 

11. Defaults and Remedies. Each of the following constitutes an Event of Default with respect to the Notes: (i) default in the
payment of any installment of interest upon the Notes as and when due and payable, and continuance of such default for a period of 30 days; (ii) default in the payment of all or any part of the principal on any of the Notes as and when the same
shall become due and payable either at Stated Maturity, upon any redemption, by declaration or otherwise; (iii) default in the performance, or breach, of any covenant or agreement of the Issuer or the Guarantor in respect of the Notes (other
than a covenant or agreement in respect of the Notes a default in the performance of which or the breach of which is elsewhere in this Section is specifically dealt with) and continuance of such default or breach for a period of 60 days (or 180 days
in the case of a Reporting Failure) after there has been given to the Issuer and the Guarantor by the Trustee or to the Issuer, the Guarantor and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding Notes, a
written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; (iv) certain events of bankruptcy, insolvency or reorganization with respect to the
Issuer or, if and so long as the Notes are guaranteed by a Guarantor, such 

  
 Exhibit A-5 

 
Guarantor; (v) any Guarantee ceasing to be in full force and effect (except as otherwise provided in the Indenture), being declared in any judicial proceeding to be null and void, or being
denied or disaffirmed by the applicable Guarantor; and (vi) either (1) default in the payment of any Indebtedness of the Issuer, the Guarantor or any Subsidiary of the Issuer after the expiration of any applicable grace period after final
maturity or (2) the acceleration of Indebtedness of the Issuer, the Guarantor or any Subsidiary of the Issuer by the holders thereof because of a default and, in either case, the total amount of the Indebtedness unpaid or accelerated exceeds
$50 million; provided, however, that the occurrence of any of the events described in clause (iii) above shall not constitute an Event of Default if such occurrence is the result of changes in generally accepted accounting principles as
recognized by the American Institute of Certified Public Accountants at the date as of which this Indenture is executed and a certificate to such effect is delivered to the Trustee by the Issuer’s independent public accountants. 

If any Event of Default, other than one described in clause (iv) above, occurs and is continuing, then, unless the principal of and
accrued and unpaid interest on all the Notes shall have already become due and payable, either the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare the principal of and interest on all
the Notes to be due and payable. In the case of an Event of Default arising from certain events of bankruptcy or insolvency, then in each and every such case, unless the principal of and accrued and unpaid interest on all the Notes shall have
already become due and payable, the principal of and interest on all the Notes shall become due and payable immediately, without further action or notice. 

Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders of not less
than a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default (except a Default relating
to the payment of principal, premium, if any, or interest) if the Trustee determines in good faith that withholding notice is in the Holders’ interests. The Holders of not less than a majority in aggregate principal amount of the Notes then
Outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any past Default or Event of Default and its consequences under the Indenture except a Default or Event of Default in the payment of interest on, the
principal of, or premium, if any, on, the Notes or an Event of Default relating to a provision of the Indenture that cannot be amended without the consent of each Holder affected thereby. The Partnership is required to deliver to the Trustee
annually a statement regarding compliance with the Indenture, and the Partnership is required within 30 days after the occurrence of any Default or Event of Default to deliver to the Trustee a statement specifying such Default or Event of Default
and certain additional information. 
 12. Authentication. This Note shall not be valid until authenticated by the manual signature
of the Trustee or an authenticating agent. 
 13. Abbreviations. Customary abbreviations may be used in the name of a Holder or an
assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

  
 Exhibit A-6 

 14. CUSIP and ISIN Numbers. Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures, the Issuer has caused CUSIP and corresponding ISIN numbers to be printed on the Notes, and the Trustee may use CUSIP and corresponding ISIN numbers in notices of redemption as a convenience to Holders. No
representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon. 

The Issuer shall furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:
