 RECITALS OF THE ISSUER AND THE GUARANTORS 

WHEREAS, the Issuer and the Guarantors have heretofore executed and delivered to the Trustee an Indenture, dated as of
August 15, 2013 (the “Original Indenture”), providing for the issuance from time to time of its unsecured senior debentures, notes or other evidences of Indebtedness (the “Securities”), to be issued in one or
more series as provided in the Original Indenture; 
 WHEREAS, Section 9.01 of the Original Indenture provides that
the Issuer, each Guarantor and the Trustee may from time to time enter into one or more indentures supplemental thereto to establish a new series of Securities and add certain provisions to the Original Indenture; 

WHEREAS, Sections 2.01 and 3.01 of the Original Indenture provide that the Issuer may enter into one or more indentures supplemental
thereto to establish the form and terms of a series of Securities issued pursuant to the Original Indenture; 
 WHEREAS,
the Issuer, pursuant to the foregoing authority, proposes in and by this First Supplemental Indenture (this “Supplemental Indenture” and, together with the Original Indenture, the “Indenture”) to supplement the
Original Indenture insofar as it will apply only to two series of securities to be known as the Issuer’s 4.625% Senior Notes due 2023 (the “2023 Notes”) and the 6.125% Senior Notes due 2043 (the “2043 Notes”
and together with the 2023 Notes, the “Notes”) issued hereunder (and not to any other series); 

WHEREAS, the Issuer and the Guarantors have duly authorized the execution and delivery of this Supplemental Indenture; and 

WHEREAS, all things necessary have been done to make this Supplemental Indenture, the Notes and the Guarantees valid agreements of the
Issuer and the Guarantors, in accordance with their terms and the terms of the Original Indenture. 

 NOW, THEREFORE, for and in consideration of the premises and the covenants and agreements
contained herein, and for other good and valuable consideration the receipt of which is hereby acknowledged, the parties hereto agree as follows: 
 ARTICLE I 
 4.625% Senior Notes due 2023 and 

6.125% Senior Notes due 2043 
 SECTION 1.01. Creation of Series; Establishment of Form. 
 (1) There
is hereby established two new series of Securities under the Indenture entitled “4.625% Senior Notes due 2023” and “6.125% Senior Notes due 2043”. 

(2) The Notes, including the form of the certificate of authentication, shall be in substantially the respective forms attached hereto as
Exhibits A and B. 
 (3) The Trustee shall authenticate and deliver the Notes for original issue in an aggregate principal
amount of $250,000,000 for the 2023 Notes and $275,000,000 for the 2043 Notes upon an Issuer Order for the authentication and delivery of the Notes. The Issuer may from time to time issue additional Notes in accordance with Sections 3.01 and 9.01 of
the Original Indenture. Any additional Notes of either series subsequently issued shall not be limited by the aggregate principal amount of this Supplemental Indenture. Each series of Notes issued originally hereunder, together with any additional
Notes of such series subsequently issued, shall be treated as a single series for purposes of the Indenture. 
 (4) The Notes
shall be issued in registered form without coupons. 
 (5) The Notes shall not have a sinking fund. 

(6) The principal of the 2023 Notes shall be due on August 15, 2023 and the principal of the 2043 Notes shall be due on
August 15, 2043. 
 (7) The outstanding principal amount of the 2023 Notes shall bear interest at the rate of
4.625% per annum, and the outstanding principal amount of the 2043 Notes shall bear interest at the rate of 6.125% per annum, both from August 15, 2013 or from the most recent Interest Payment Date (as defined below) to which interest
has been paid or duly provided for, as the case may be, payable semi-annually in arrears on February 15 and August 15 (each, an “Interest Payment Date”), commencing on February 15, 2014, to the Persons in whose names
the Notes are registered at the close of business on the Regular Record Date (as defined in Section 1.02) for such interest and at the Stated Maturity of the Notes, until the principal thereof is paid or made available for payment. Interest on
the Notes will be computed on the basis of a 360-day year comprised of twelve 30-day months. Any such interest due on an Interest Payment Date that is not so punctually paid or duly provided for shall forthwith cease to be payable to the Holders on
such Regular Record Date and may either be paid to the Person or Persons in whose name the Notes are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Issuer pursuant to
Section 3.07 of the Original Indenture, notice whereof shall be given to Holders of the Notes not less than ten (10) days prior to such 

  
 2 

 
Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Notes may be listed, and upon such
notice as may be required by any such exchange, all as more fully provided in the Original Indenture. 
 (8) The Notes shall be
issued in denominations of $2,000 or any integral multiple of $1,000 in excess thereof. 
 (9) The Notes shall be
redeemable, in whole at any time or in part from time to time, at the option of the Issuer on any date (a “Redemption Date”), at a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be
redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest to maturity thereon (exclusive of interest accrued to, but excluding, such Redemption Date) discounted to, but excluding, such
Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 35 basis points, with respect to the redemption of the 2023 Notes and 40 basis points with respect to the redemption of the
2043 Notes plus, in either case, accrued and unpaid interest on the principal amount being redeemed to, but excluding, such Redemption Date.

Treasury Issue (if no maturity is within three (3) months before or after the remaining term of the respective series of Notes being redeemed, yields for the two published maturities most closely corresponding to the applicable Comparable
Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (b) if such release (or any successor release) is not published during
the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the applicable Comparable Treasury Issue, calculated using a price for the applicable Comparable

if any, (except, in the case of interest, where the Redemption Date is an Interest Payment Date) shall be made at the office of the Paying Agent upon surrender of such Notes to the Paying Agent and (ii) payments of interest shall be made, at
the option of the Issuer, subject to such surrender where applicable, (A) by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (B) by wire transfer at such place and to such

(3) The Trustee shall initially serve as the Paying Agent with respect to the Notes, with the Place of Payment initially being the
Corporate Trust Office. 
 SECTION 1.04. Global Securities. Each series of the Notes shall initially be issued in
the form of one or more Global Securities registered in the name of a nominee of the Depositary. Except under the limited circumstances described below, Notes represented by such Global Security or Global Securities shall not be exchangeable for,
and shall not otherwise be issuable as, Notes in definitive form. The Issuer has entered into a letter of representations with the Depositary in the form provided by the Depositary and the Trustee and each Paying Agent, Security Registrar or other
agent is hereby authorized to act in accordance with such letter and applicable Depositary procedures. The Global Securities described above may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of
the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary, unless and until the
Notes are exchanged in whole or in part for Notes in definitive form. 
 Subject to the procedures of the Depositary, a
Global Security representing the Notes of either series shall be exchangeable for Notes of such series registered in the names of Persons other than the Depositary or its nominee only if (i) the Depositary notifies the Trustee and the Issuer in
writing that it is no longer willing or able to properly discharge its responsibilities as a Depositary for such Global Security and no qualified successor Depositary shall have been appointed by the Issuer within ninety (90) days of receipt by
the Issuer of such notification, or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act at a time when the Depositary is required to be so registered to act as such Depositary and no qualified successor
Depositary shall have been appointed by the Issuer within ninety (90) days after it becomes aware of such cessation, (ii) the Issuer executes and delivers to the Trustee an Issuer Order stating that the Issuer elects to terminate the
book-entry system through the Depositary, or (iii) there shall have occurred and be continuing an Event of Default with respect to such Global Security. Any Global Security that is exchangeable pursuant to the preceding sentence shall be
exchangeable for the Notes it represents, as provided in the Original Indenture. 

  
 6 

 SECTION 1.05. Redemption. 

(1) The Issuer shall mail notice of any redemption pursuant to Section 1.01(9) not less than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of the Notes to be redeemed. The Issuer shall deliver to the Trustee an Officers’ Certificate setting forth the Redemption Price with respect to the foregoing redemption no later than two (2) Business Days
prior to the Redemption Date. The Trustee shall have no responsibility for determining said Redemption Price on the Redemption Date, and from and after such date (unless the Issuer shall default in the payment of the Redemption Price and accrued
interest) such Notes shall cease to bear interest. 
 (2) Section 11.03 (Selection by Trustee of Securities to Be Redeemed)
of the Original Indenture is hereby amended and restated in its entirety as follows: 
 If less than all the
4.625% Senior Notes due 2023 and/or the 6.125% Senior Notes due 2043 are to be redeemed, the particular Notes to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Notes not
previously called for redemption, by such method as the Trustee shall deem fair and appropriate or in accordance with the procedures of the Depositary, and which may provide for the selection for redemption of portions (equal to $1,000 or any
integral multiple thereof) of the principal amount of Notes of a denomination larger than $2,000; provided, however, that Notes registered in the name of the Issuer shall be excluded from any such selection for redemption until all Notes being
redeemed and that are not so registered shall have been previously selected for redemption. 
 The Trustee shall
promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of
Notes shall relate, in the case of any Notes redeemed or to be redeemed only in part, to the portion of the principal amount of such Notes which has been or is to be redeemed. 
 SECTION 1.06. Purchase of Notes Upon a Change of Control Triggering Event. 

(1) If a Change of Control Triggering Event occurs, unless the Issuer has exercised its right to redeem the Notes pursuant to Sections
1.01(9) and 1.05 of this Supplemental Indenture or Article ELEVEN of the Original Indenture, the Issuer will make an offer to each Holder of Notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000 principal
amount) of that Holder’s Notes at a repurchase price in cash equal to 101% of the 

  
 7 

 
aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to but excluding the date of repurchase. Within 30 days following any Change of
Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Issuer will mail a notice to each Holder describing the transaction or transactions that
constitute or may constitute the Change of Control Triggering Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 45 days from the date such notice is
mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to repurchase is conditioned on the Change of Control Triggering Event occurring on or prior to the payment date specified in the
notice. 
 (2) The Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws
and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations
conflict with the Change of Control Triggering Event provisions of the Notes, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering
Event provisions of the Notes by virtue of such conflict. 
 (3) On the Change of Control Triggering Event payment date, the
Issuer will, to the extent lawful: 
 (a) accept for payment all Notes or portions of Notes properly tendered
pursuant to the Issuer’s offer; 
 (b) deposit with the Paying Agent an amount equal to the aggregate
purchase price in respect of all Notes or portions of Notes properly tendered; and 
 (c) deliver or cause to be
delivered to the Trustee, the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchase by the Issuer. 

(4) The Paying Agent will promptly pay, from funds deposited by the Issuer for such purpose, to each Holder of Notes properly tendered
the purchase price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new note equal in principal amount to any unpurchased portion of any Notes surrendered. 

(5) The Issuer will not be required to make an offer to repurchase the Notes upon a Change of Control Triggering Event if a third party
makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and such third party purchase all Notes properly tendered and not withdrawn under its offer. 

  
 8 

 SECTION 1.07. Additional Covenants. The following shall be additional
covenants to the covenants set forth in the Original Indenture for the benefit of the Notes only and shall be effective only so long as the Notes are Outstanding: 
 (1) Limitation on Liens. Parent shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, incur or suffer to exist any Lien, other than a Permitted Lien (an
“Initial Lien”), securing Indebtedness upon any Capital Stock of any Significant Subsidiary of Parent that is owned, directly or indirectly, by Parent or any of its Subsidiaries, in each case whether owned at the date of the
original issuance of the Notes or thereafter acquired, or any interest therein or any income or profits therefrom unless it has made or will make effective provision whereby the Outstanding Notes will be secured by such Lien equally and ratably with
(or prior to) all other Indebtedness of Parent or any Subsidiary secured by such Lien. Any Lien created for the benefit of the Holders of the Notes pursuant to the preceding sentence shall provide by its terms that such Lien will be automatically
and unconditionally released and discharged upon release and discharge of the Initial Lien. 
 “Permitted
Lien” means a Lien on the Capital Stock of a Significant Subsidiary to secure Indebtedness incurred to finance the purchase price of such Capital Stock; provided that any such Lien may not extend to any other property of Parent or
any other Subsidiary of Parent; and provided further that such Indebtedness matures within 180 days from the date such Indebtedness was incurred. 
 (2) Limitation on Dispositions of Significant Subsidiaries. Parent shall not, and shall not permit any of its Subsidiaries to, directly or indirectly, sell, transfer or otherwise dispose of,
and will not permit any Significant Subsidiary to issue, any Capital Stock of any Significant Subsidiary. Notwithstanding the foregoing limitation, (a) Parent and its Subsidiaries may sell, transfer or otherwise dispose of, and any Significant
Subsidiary may issue, any such Capital Stock to any Subsidiary of Parent, (b) any Subsidiary of Parent may sell, transfer or otherwise dispose of, and any Significant Subsidiary may issue, any such securities to Parent or another Subsidiary of
Parent, (c) Parent and its Subsidiaries may sell, transfer or otherwise dispose of, and any Significant Subsidiary may issue, any such Capital Stock if the consideration received is at least equal to the fair market value (as determined by the
Board of Directors acting in good faith) of such Capital Stock, and (d) Parent and its Subsidiaries may sell, transfer or otherwise dispose of, and any Significant Subsidiary may issue, any such securities if required by law or any regulation
or order of any governmental or regulatory authority. Notwithstanding the foregoing, Parent may merge or consolidate any of its Significant Subsidiaries into or with another one of its Significant Subsidiaries and may otherwise convey, transfer or
lease its properties and assets pursuant to Article EIGHT of the Original Indenture. 
 SECTION 1.08. Early
Redemption for Tax Reasons. 
 (1) The Notes may be redeemed at the option of the Issuer in whole, but not in part, at
any time upon not less than 30 nor more than 60 days’ prior notice delivered electronically or by first-class mail, with a copy to the Trustee, to the registered address of each Holder, or otherwise delivered in accordance with the applicable
procedures of the Depositary if: 
 (a) on the occasion of the next payment due under the Notes, the Issuer has
or is reasonably likely to become obliged to pay Additional Amounts (as defined in Section 1.09) as a result of any change in, or amendment to, the laws or regulations of a Taxing Jurisdiction (as defined in Section 1.09), or any change in
the official application or official interpretation of such laws or regulations, which change or amendment is announced and becomes effective on or after the date of issuance of the Notes (a “Change in Tax Law”); and 

(b) such obligation cannot be avoided by the Issuer taking reasonable measures available to it; 

  
 9 

 provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on
which the Issuer would be obliged to pay such Additional Amounts were a payment in respect of the Notes then due. 
 (2) Prior
to the giving of any notice of redemption pursuant to the Indenture, the Issuer shall deliver to the Trustee an Officers’ Certificate of the Issuer stating that the Issuer is entitled to effect such redemption and setting forth a statement of
facts showing that the conditions precedent to the right of the Issuer so to redeem have occurred. Notes redeemed pursuant to this Section 1.08 will be redeemed at a Redemption Price equal to 100% of the principal amount of the Notes being
redeemed plus accrued and unpaid interest thereon to, but excluding, the date of redemption and all Additional Amounts due on the date of redemption. 
 SECTION 1.09. Additional Amounts. With respect to any payments made by or on the behalf of the Issuer or a Guarantor in respect of the Notes or any Guarantee of the Notes, as applicable, the
Issuer or such Guarantor will make all payments of principal of, premium, if any, and interest on (whether on scheduled payment dates or upon acceleration) and the Redemption Price, if any, payable in respect of any Note without deduction or
withholding for or on account of any present or future tax, duty, levy, import, assessment or other governmental charge (including penalties, interest and other liabilities related thereto (“Taxes”) imposed, levied, collected,
withheld or assessed by or on behalf of any jurisdiction in which the Issuer or such Guarantor is incorporated or organized, engaged in business for tax purposes or otherwise resident for tax purposes, or any political subdivision thereof or taxing
authority therein and any jurisdiction through which any payment is made on behalf of the Issuer or any Guarantor (including the jurisdiction of any Paying Agent) (each, a “Taxing Jurisdiction”), upon or as a result of such
payments, unless required by law or by the official interpretation or administration thereof. 
 To the extent
that any such Taxes are so levied or imposed, the Issuer or such Guarantor will pay such additional amounts (“Additional Amounts”) in order that the net amount received by each Holder (including Additional Amounts), after
withholding for or on account of such Taxes imposed upon or as a result of such payment, will not be less than the amount that would have been received had such taxes not been imposed or levied; except that no such Additional Amounts shall be
payable with respect to a payment made to a Holder or beneficial owner of a Note: 
 (1) to the extent that such Taxes
would not have been so imposed, levied or assessed but for the existence of some connection between such Holder or beneficial owner of such Note and the Taxing Jurisdiction imposing such Taxes other than the mere holding or enforcement of such Note
or receipt of payments thereunder; or 

  
 10 

 (2) to the extent that such Taxes would not have been so imposed, levied or assessed but for
the failure of the Holders or beneficial owners of such Note to comply with a reasonable written request by the Issuer (or its agent) to make a valid declaration of non-residence or any other claim or filing for exemption to which it is entitled
(but only to the extent it is legally entitled to do so); or 
 (3) that presents such Note for payment (where presentation is
required) more than 30 days after the date on which such payment became due and payable or the date on which payment of the Note is duly provided for and notice is given to Holders, whichever occurs later, except to the extent that the Holder or
beneficial owner of such Note would have been entitled to such Additional Amounts on presenting such Note on any date during such 30-day period; or 
 (4) where such withholding or deduction is imposed on a payment to or for an individual and is required to be made pursuant to Council Directive 2003/48/EC on the taxation of savings income or any law
implementing or complying with, or introduced in order to conform to, such Directive; or 
 (5) that presents such Note for
payment (where presentation is required) by or on behalf of the Holders of such Note to any Paying Agent if such withholding or deduction of such Taxes could have been avoided by presenting such Note to another Paying Agent in a member state of the
European Union; 
 (6) in the case of a payment made by or on behalf of a Guarantor organized under the laws of the United
States, any state thereof or the District of Columbia, with respect to any United States withholding taxes, so long as the Issuer or such Guarantors (pursuant to Section 1.06 of the Original Indenture) provides reasonable notice regarding
potential United States withholding taxes and requests Holders and beneficial owners to provide applicable U.S. tax forms; or 

(7) any combination of the above. 
 As used herein and for purposes of the Indenture and the Notes, any reference to the principal of and interest on the Notes and the Redemption Price, if any, shall be deemed to include a reference to any
related Additional Amounts payable in respect of such amounts. The Issuer will also pay any stamp, registration, excise or property taxes and any other similar levies (including any interest and penalties related thereto) imposed by any Taxing
Jurisdiction on the execution, delivery, registration or enforcement of any of the Notes, the Guarantees, the Indenture or any other document or instrument referred to therein.

of at least 25% in principal amount of the Outstanding Notes of such series 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; or

 (4) a default under any Indebtedness by the Issuer, any Guarantor or any of their respective subsidiaries that results in
acceleration of the maturity of such Indebtedness, or failure to pay any such Indebtedness at maturity, in an aggregate amount greater than $30.0 million or its foreign currency equivalent at the time, provided that the cure of such default shall
remedy such Event of Default under this Section 1.10(4); or 
 (5) the entry by a court having jurisdiction in the premises

relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or 
 (6) the commencement
by Parent, the Issuer or any Significant Subsidiary of a voluntary case or proceeding under any applicable Bankruptcy Law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or
order for relief in respect of Parent, the Issuer or any Significant Subsidiary in an involuntary case or proceeding under any applicable Bankruptcy Law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the
filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Bankruptcy Law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a Custodian of Parent, the
Issuer or any Significant Subsidiary of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the
taking of corporate action by Parent, the Issuer or any Significant Subsidiary in furtherance of any such action, or the taking of any comparable action under any foreign laws relating to insolvency; or

been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of, premium, if any, or interest on any such Note or in the payment of any sinking fund or analogous obligation installment
with respect to such Notes, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines
that the withholding of such notice is in the interest of the Holders of such Notes; and provided, further, that in the case of any default of the character specified in Section 1.10(3) with respect to such Notes, no such notice

supplemented by the First Supplemental Indenture, dated as of August 15, 2013 (herein called the “First Supplemental Indenture”) (such Original Indenture, together with the First Supplemental Indenture, the “Indenture”),

guarantors (collectively, the “Guarantors”) and WELLS FARGO BANK, NATIONAL ASSOCIATION, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), and reference is hereby made to the
Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Note is one of the series designated on the face hereof (herein called the “Notes”). 
 The Notes may be redeemed at the option of the Issuer in whole, but not in part, at any time upon not less than 30 nor more than 60 days’ prior notice delivered electronically or by first-class mail,
with a copy to the Trustee, to the registered address of each Holder or otherwise delivered in accordance with the applicable procedures of the Depositary, if: 
 (i) on the occasion of the next payment due under the Notes, the Issuer has or will become obliged to pay Additional Amounts (as defined below) as a result of any change in, or amendment to, the laws or
regulations of the Taxing Jurisdiction (defined below), or any change in the official application or official interpretation of such laws or regulations, which change or amendment is announced and becomes effective on or after the date of issuance
of the Notes (a “Change in Tax Law”); and 
 (ii) such obligation cannot be avoided by the Issuer
taking reasonable measures available to it; provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment in respect of
the Notes then due. 
 Upon the occurrence of a Change of Control Triggering Event, unless the Issuer has exercised its right to
redeem the Notes pursuant to Sections 1.01 and 1.05 of the First 

 
Supplemental Indenture or Article ELEVEN of the Original Indenture, each Holder will have the right to require that the Issuer repurchase all or any part (in excess of $2,000 and in integral
multiples of $1,000 principal amount) of that Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to but excluding the
date of repurchase. Within 30 days following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Issuer will mail a notice to each
Holder describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and
no later than 45 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to repurchase is conditioned on the Change of Control Triggering Event occurring
on or prior to the payment date specified in the notice. 
 The Issuer will comply with the requirements of Rule 14e-1 under the
Securities Exchange Act of 1934, as amended (the “Exchange Act”) and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change
of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Notes, the Issuer will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Notes by virtue of such conflict. 
 On the Change of Control Triggering Event payment date, the Issuer will, to the extent lawful: 
 (i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Issuer’s offer; 
 (ii) deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Notes or portions of Notes properly tendered; and 

(iii) deliver or cause to be delivered to the Trustee, the Notes properly accepted, together with an Officers’
Certificate stating the aggregate principal amount of Notes being purchase by the Issuer. 
 The Paying Agent will promptly pay,
from funds deposited by the Issuer for such purpose, to each Holder of Notes properly tendered the purchase price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new note
equal in principal amount to any unpurchased portion of any Notes surrendered. 
 The Issuer will not be required to make an
offer to repurchase the Notes upon a Change of Control Triggering Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Issuer and such third party purchase all
Notes properly tendered and not withdrawn under its offer.

Note: 
 (i) to the extent that such Taxes would not have been so imposed, levied or assessed but for the
existence of some connection between such Holder or beneficial owner of such Note and the Taxing Jurisdiction imposing such Taxes other than the mere holding or enforcement of such Note or receipt of payments thereunder; or 

(ii) to the extent that such Taxes would not have been so imposed, levied or assessed but for the failure of the Holder or
beneficial owner of such Note upon reasonable request by the Issuer (provided pursuant to the applicable notice provision) to make a declaration of non-residence or any other claim or filing for exemption to which it is entitled ; or 

(iii) presented for payment (when the Notes are in the form of definitive Notes) more than 30 days after the date on which
such payment became due and payable or the date on which payment of the Note is duly provided for and notice is given to Holders, whichever occurs later, except to the extent that the Holder or beneficial owner of such Note would have been entitled
to such Additional Amounts on presenting such Note on any date during such 30-day period; or 

  
 4 

 (iv) where such withholding or deduction is imposed on a payment to or for
an individual and is required to be made pursuant to Council Directive 2003/48/EC or any law implementing or complying with, or introduced in order to conform to, such Directive; or 

(v) presented for payment (when the Notes are in the form of definitive Notes) by or on behalf of the Holder of such Note
to any Paying Agent if such withholding or deduction of such Taxes could have been avoided by presenting such Note to another Paying Agent in a member state of the European Union; or 

(vi) with respect to any United States withholding taxes, so long as the Issuer or such Guarantors (pursuant to the
applicable notice provision) provides notice regarding potential United States withholding taxes and requests Holders and beneficial owners to provide applicable U.S. tax forms; or 

(vii) any combination of the above. 
 As used herein and for purposes of this Note, any reference to the principal of and interest on the Notes and the Redemption Price, if any, shall be deemed to include a reference to any related Additional
Amounts payable in respect of such amounts. The Issuer will also pay any stamp, registration, excise or property taxes and any other similar levies imposed by any Taxing Jurisdiction on the execution, delivery, registration or enforcement of any of
the Notes, the Indenture or any other document or instrument referred to therein. 
 The Issuer may, from time to time, without
notice to or the consent of the Holders of the Notes, increase the principal amount of the Notes under the Indenture and issue such increased principal amount (or any portion thereof), in which case any additional Notes so issued will have the same
form and terms (other than the date of issuance and the issue price and, under certain circumstances, the date from which interest thereon will begin to accrue and the initial Interest Payment Date), and will carry the same right to receive accrued
and unpaid interest, as the Notes previously issued, and such additional Notes will form a single series with the previously issued Notes, including for voting purposes. 
 No sinking fund is provided for the Notes. The Notes are subject to redemption upon not less than 30 nor more than 60 days’ notice given as provided in the Indenture, as a whole at any time, or in
part from time to time, at the election of the Issuer, at the Redemption Price, which shall be equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining
scheduled payments to maturity of principal and interest thereon (exclusive of interest accrued to, but excluding, such Redemption Date) discounted to, but excluding, such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate plus 35 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to, but excluding, such Redemption Date. 

In the case of any such redemption, the Issuer will also pay accrued and unpaid interest, if any, to, but excluding, the Redemption Date.

 The definitions of certain terms used in the paragraph above are listed below. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
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 comparable maturity to
the remaining term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption Date for the
Notes, (1) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than five
such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Independent Investment Banker”
means one of the Reference Treasury Dealers that the Issuer appoints to act as the Independent Investment Banker from time to time. 
 “Reference Treasury Dealer” means (1) each of Barclays Capital Inc. and Morgan Stanley & Co. LLC and their respective successors; provided, however, that if any of the foregoing
ceases to be a primary dealer of U.S. government securities in the United States (a “Primary Treasury Dealer”), the Issuer shall substitute another Primary Treasury Dealer and (2) any other Primary Treasury Dealers selected by the
Issuer. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any
Redemption Date, the average, as determined by the Independent Investment Banker, 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 Independent
Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 “Treasury
Rate” means, with respect to any Redemption Date: (a) the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15
(519)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption
“Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes yields for the two published maturities most closely
corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (b) if such release (or any successor
release) is not published during the week preceding the calculation date or does not contain such yields, 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. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 

In the event of redemption of this Note in part only, a new Note or Notes of like tenor for the unredeemed portion hereof will be issued
in the name of the Holder hereof upon the cancellation hereof. 

  
 6

 If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared
due and payable in the manner and with the effect provided in the Indenture.

as therein provided, the amendment thereof and the modification of the rights and obligations of the Issuer and the Guarantors and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the
Issuer, the Guarantors and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the
Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Issuer with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a
receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than a majority in principal amount
of the Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity, and the Trustee shall not have received from the Holders
of a majority in principal amount of Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The
foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof (or premium, if any) or interest hereon on or after the respective due dates expressed or provided for herein.

 No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation
of the Issuer, which is absolute and unconditional, to pay the principal of and any premium and interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the
Security Register, upon surrender of this Note for

denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 The
Notes are issuable only in registered form without coupons in denominations of $2,000 or any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable
for a like aggregate principal amount of Notes of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be made for any such registration of transfer or exchange, but the Issuer or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. 
 Prior to due presentment of this Note for registration of transfer, the Issuer, any
Guarantor, the Trustee and any agent of the Issuer, any Guarantor or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes (subject to Section 3.07 of the Original Indenture), whether or not

Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Issuer, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered. This Note is one of the series designated on the face hereof (herein called the “Notes”). 
 The Notes may be redeemed at the option of the Issuer in whole, but not in part, at any time upon not less than 30 nor more than 60 days’ prior notice delivered electronically or by first-class mail,
with a copy to the Trustee, to the registered address of each Holder or otherwise delivered in accordance with the applicable procedures of the Depositary, if: 
 (i) on the occasion of the next payment due under the Notes, the Issuer has or will become obliged to pay Additional Amounts (as defined below) as a result of any change in, or amendment to, the laws or
regulations of the Taxing Jurisdiction (defined below), or any change in the official application or official interpretation of such laws or regulations, which change or amendment is announced and becomes effective on or after the date of issuance
of the Notes (a “Change in Tax Law”); and 
 (ii) such obligation cannot be avoided by the Issuer
taking reasonable measures available to it; provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Issuer would be obliged to pay such Additional Amounts were a payment in respect of
the Notes then due.

requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase

applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Notes by virtue of such conflict.

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Issuer’s offer; 

(ii) deposit with the Paying Agent an amount equal to the aggregate purchase price in respect of all Notes or portions of
Notes properly tendered; and 
 (iii) deliver or cause to be delivered to the Trustee, the Notes properly
accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being purchase by the Issuer. 
 The Paying Agent will promptly pay, from funds deposited by the Issuer for such purpose, to each Holder of Notes properly tendered the purchase price for the Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book-entry) to each Holder a new note equal in principal amount to any unpurchased portion of any Notes surrendered. 
 The Issuer will not be required to make an offer to repurchase the Notes upon a Change of Control Triggering Event if a third party makes an offer in the manner, at the times and otherwise in compliance

(i) to the extent that such Taxes would not have been so imposed, levied or assessed but for the existence of some
connection between such Holder or beneficial owner of such Note and the Taxing Jurisdiction imposing such Taxes other than the mere holding or enforcement of such Note or receipt of payments thereunder; or 

(ii) to the extent that such Taxes would not have been so imposed, levied or assessed but for the failure of the Holder or

 8 

 (iii) presented for payment (when the Notes are in the form of definitive
Notes) more than 30 days after the date on which such payment became due and payable or the date on which payment of the Note is duly provided for and notice is given to Holders, whichever occurs later, except to the extent that the Holder or
beneficial owner of such Note would have been entitled to such Additional Amounts on presenting such Note on any date during such 30-day period; or 
 (iv) where such withholding or deduction is imposed on a payment to or for an individual and is required to be made pursuant to Council Directive 2003/48/EC or any law implementing or complying with, or
introduced in order to conform to, such Directive; or 
 (v) presented for payment (when the Notes are in the
form of definitive Notes) by or on behalf of the Holder of such Note to any Paying Agent if such withholding or deduction of such Taxes could have been avoided by presenting such Note to another Paying Agent in a member state of the European Union;
or 
 (vi) with respect to any United States withholding taxes, so long as the Issuer or such Guarantors
(pursuant to the applicable notice provision) provides notice regarding potential United States withholding taxes and requests Holders and beneficial owners to provide applicable U.S. tax forms; or

the Notes, the Indenture or any other document or instrument referred to therein. 
 The Issuer may, from time to time, without
notice to or the consent of the Holders of the Notes, increase the principal amount of the Notes under the Indenture and issue such increased principal amount (or any portion thereof), in which case any additional Notes so issued will have the same
form and terms (other than the date of issuance and the issue price and, under certain circumstances, the date from which interest thereon will begin to accrue and the initial Interest Payment Date), and will carry the same right to receive accrued
and unpaid interest, as the Notes previously issued, and such additional Notes will form a single series with the previously issued Notes, including for voting purposes. 
 No sinking fund is provided for the Notes. The Notes are subject to redemption upon not less than 30 nor more than 60 days’ notice given as provided in the Indenture, as a whole at any time, or in
part from time to time, at the election of the Issuer, at the Redemption Price, which shall be equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) the sum of the present values of the remaining
scheduled payments to maturity of principal and interest thereon (exclusive of interest accrued to, but excluding, such Redemption Date) discounted to, but excluding, such Redemption Date on a semi-annual basis (assuming a 360-day

  
 9 

 
year consisting of twelve 30-day months) at the Treasury Rate plus 40 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to, but excluding,
such Redemption Date. 
 In the case of any such redemption, the Issuer will also pay accrued and unpaid interest, if any, to,
but excluding, the Redemption Date. 
 The definitions of certain terms used in the paragraph above are listed below.

 “Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker
as having a 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 comparable
maturity to the remaining term of such Notes. 
 “Comparable Treasury Price” means, with respect to any Redemption
Date for the Notes, (1) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains
fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Independent Investment
Banker” means one of the Reference Treasury Dealers that the Issuer appoints to act as the Independent Investment Banker from time to time. 
 “Reference Treasury Dealer” means (1) each of Barclays Capital Inc. and Morgan Stanley & Co. LLC and their respective successors; provided, however, that if any of the foregoing
ceases to be a primary dealer of U.S. government securities in the United States (a “Primary Treasury Dealer”), the Issuer shall substitute another Primary Treasury Dealer and (2) any other Primary Treasury Dealers selected by the
Issuer. 
 “Reference Treasury Dealer Quotations means, with respect to each Reference Treasury Dealer and any Redemption
Date, the average, as determined by the Independent Investment Banker, 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 Independent Investment
Banker at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 “Treasury Rate”
means, with respect to any Redemption Date: (a) the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15 (519)” or any
successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant
Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the remaining term of the Notes yields for the two published maturities most closely corresponding to the
Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or (b) if such release (or any successor release) is not
published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the 

  
 10 

 
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. The Treasury Rate will be calculated on the third Business Day preceding the Redemption Date. 
 In the event
of redemption of this Note in part only, a new Note or Notes of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

 4.2 Scheduling. 

4.2.1 Scheduling and Time Extensions. Attached as Exhibit E to this Agreement is a progress schedule
(“Project Schedule”) setting forth the durations for all the major items of Work to be performed; the start and finish date of all such activities; the performance tests; and the Completion Date of the Project. EPC Contractor shall submit
to Owner updated Progress Schedules each month to reflect the actual progress made and to forecast future progress of the Work. The Completion Date shall be extended only for such number of calendar days as the Work is actually delayed by acts of
God, acts or omissions of Owner, delays in the issuance of required permits occurring after September 1, 2013, the presence of any undisclosed hazardous substances (including, but not limited to Hazardous Materials) affecting the Work, a
casualty, change in law, flood, fire, or a change order, plus a reasonable number of additional days to allow EPC Contractor to resume Work following such delay, and only then if it is not feasible for EPC Contractor to avoid or to mitigate the
impact of the delay (“Unavoidable Excusable Delay”). No extensions to the Completion Date shall be granted due to the negligence or fault of EPC Contractor or its Subcontractors or untimely delivery of equipment or the non-availability of
materials or labor, not including the Owner-Furnished Equipment and materials. In order to obtain a time extension due to an Unavoidable Excusable Delay, EPC Contractor must give written notice to Owner within five (5) working days after the
commencement of each Unavoidable Excusable Delay, including a description of actions taken to avoid or mitigate the delay and a proposed action plan or re-sequencing to minimize the impact on the Project. 

4.3 Liquidated Damages. It is mutually agreed that if EPC Contractor does not complete the Work to the point of Final Completion
by the Completion Date, Owner will sustain damage, the precise amount of which is difficult to determine at the time of making this Agreement. 
 4.3.1 Up to a maximum total amount of $500,000, EPC Contractor shall pay to Owner as liquidated damages and not as a penalty the sum of $5,000 per day for each full day of delay if EPC Contractor
fails to achieve Mechanical Completion by September 30, 2015 (subject to automatic extension for Unavoidable Excusable Delay), provided such delay is due to a) failure by EPC Contractor to prosecute the Work with diligence, or b) EPC
Contractor’s or Subcontractor’s negligence. 
 EPC Contractor further agrees that any assessment by Owner of liquidated damages or
payment by EPC Contractor to Owner of liquidated damages is to compensate Owner only for the damages arising out of EPC Contractor’s delay in achieving the Completion Date, and is not a release of any of Owner’s other rights or claims
against EPC Contractor, including claims of Owner for defective or improper workmanship of EPC Contractor. 
 ARTICLE 5

 PAYMENT 
 5.1 Fixed Price Portion of Work. Owner and EPC Contractor agree that EPC Contractor shall be paid for all Engineering Services and all General Conditions for a fixed price, as provided in Exhibit B.

collective liability of EPC Contractor and EPC Contractor’s officers, directors, managers, partners, employees, agents and consultants arising under, in connection with or out of this Agreement, whether in breach of contract, breach of express
or implied warranty, negligence, professional errors or omissions, strict liability, or any other legal theory of recovery, shall not exceed four and one half percent (4.5%) of the direct revenues paid to EPC Contractor by the Owner (excluding
any revenues paid to third parties by Owner or paid through EPC Contractor acting as Owner’s agent) for all variable cost portions of the Work. This limitation of liability amount was mutually negotiated. Owner acknowledges that without its
inclusion, EPC Contractor’s Fee would have been greater. EPC Contractor is not liable for damages arising from its reliance upon any data, information, specification or other documents pertaining to the Work that are provided by the Owner or
third parties providing information on behalf of Owner. 
 ARTICLE 21 

RIGHT TO OCCUPY BY OWNER 
 21.1 Early Occupancy by Owner. Owner has the right to occupy or use ahead of schedule all or any substantially completed or partially completed portion of the Project or Work when such occupancy and use
are in its best interest, notwithstanding the time of completion for all of the Work provided Owner shall be solely responsible for all risk of loss resulting from any occupancy or use of the Project or Work. Owner shall provide general liability
and builders risk insurances to cover its occupancy and use and shall be responsible for any losses, claims, expenses or damages incurred by EPC Contractor arising out of Owner’s partial occupancy or use. EPC Contractor shall be entitled to an
extension of time to the extent EPC Contractor is delayed as a result of any such early occupancy or use. 
 ARTICLE 22

 DEFAULT; RIGHT TO TERMINATE OF OWNER 
 22.1 Event of Default. 
 (a) For the purposes of this
Agreement, an Event of Default shall be if: 
 (i) at any time there shall be filed by or against EPC Contractor
in any court a petition in bankruptcy or insolvency or for reorganization or for the appointment of a receiver or trustee of all or a portion of the property of EPC Contractor, and within twenty (20) days from the filing date EPC Contractor
fails to secure a discharge; or 

  
 27 

 (ii) EPC Contractor makes an assignment for the benefit of creditors or
petitions for or enters into an agreement or arrangement with its creditors; or 
 (iii) EPC Contractor fails to
prosecute the Work properly or safely, or fails to complete the Work entirely on or before the Completion Date; or

 Overview and Assumptions 
 This Scope of Work (SOW) covers the reassembly of the 531-NH3 ammonia plant at the El Dorado Chemical Company located in El Dorado, AR (“Project”) for El Dorado Ammonia L.L.C.
(“Owner”). This SOW is specific to the ISBL (In Side Battery Limits) for this relocated/reassembled ammonia plant, and details EPC Contractor’s total efforts for the reassembly of a relocated Ammonia plant. In addition, this SOW
includes engineering and construction of OSBL (Out Side Battery Limits”) systems and equipment identified as numbers 188 (ammonia cooling tower), 189 (demineralized water system), and 190 (30,000 ton ammonia storage tank) in Section E of this
SOW (collectively “OSBL Systems”). 
 Said plant was located in Donaldsonville, LA and will be identified herein as Unit
No. 531-NH3 (“531-NH3”). Said plant has been dismantled and shipped by Owner, and will be reassembled at Owner’s Site at 4500 N. West Ave, El Dorado, AR by EPC Contractor. 531-NH3 will be reassembled in the same physical
arrangement as it was in its original location, unless otherwise specified herein. Process equipment will be set up on the same centerlines and elevations to allow the maximum reuse of piping and interconnections, as inspected by others as set forth
herein. 
 The original plant, owned by Triad, was designed and constructed in 1969 by M. W. Kellogg (MWK). The Owner purchased 531-NH3 and
relocated it to its facility in El Dorado, AR. The purchase of the 531-NH3 included the engineering documentation and maintenance records. These documents (65 banker boxes) have been scanned to electronic files (PDF’s). These records will
become part of the permanent record for this process unit. 
 A. EPC Services 

EPC Contractor shall provide EPC services for the 531-NH3 rebuild and OSBL Systems. EPC Contractor shall be responsible for the engineering, construction,
subcontractor and equipment procurement, cost controls and accounting, scheduling, estimating, invoicing, mechanical integrity, construction inspections, commissioning and startup support, and final documentation necessary to reassemble 531-NH3 at
the Site and the OSBL Systems. 
 EPC Contractor shall monitor Project progress on a continuous and ongoing basis. EPC Contractor shall conduct
weekly telephone meetings with Owner to discuss Project status and any Owner concerns. EPC Contractor will issue monthly progress reports for the duration of the Project which will generally follow the format below:

 Exhibit I 
 Certain Security, Safety and Regulatory Requirements 
 Per section 2.1.18 of the
Contract, the EPC Contractor will maintain a pro-active safety and security program, in fulfillment of and in compliance with all legal and regulatory requirements. The Site requirements include, but are not necessarily limited, to the following:

 General Contractor Requirements 
 All contractors on the Site must meet the requirements of the Owner’s S-004 “Contractor Selection and Safety Guidelines” Revision 6 dated June 18, 2013. 

Arkansas State Licensing Law for Commercial Contractors 
 The Arkansas Code and Rules and Regulations Act 150 of 1965 and Act 162 of 1987 (as amended) requires that any contractor must have a state contractor’s license to bid on and work on construction
projects in Arkansas that cost $20,000 or more. The EPC Contractor will be responsible for ensuring all subcontractors have a valid state license before performing any work on the Site. 
 U.S. Department of Labor Occupational Safety and Health Administration (OSHA) 

Compliance with all OSHA regulations is required. The two primary applicable sections are 29 CFR 1926 for the construction industry and 29 CFR 1910.119
“Process safety management of highly hazardous chemicals”. 
 OSHA 29 CFR 1926 standards most frequently applicable to construction
are: 
 1. Scaffolding 
 2. Fall
protection (scope, application, definitions) 
 3. Excavations (general requirements) 
 4. Ladders 
 5. Head protection 
 6. Excavations (requirements for protective systems) 
 7. Hazard communication 

8. Fall protection (training requirements) 
 9.
Construction (general safety and health provisions) 
 10. Electrical (wiring methods, design and protection) 

OSHA 29 CFR 1910.119 “Process safety management of highly hazardous chemicals” lists these chemicals in its Appendix A which are applicable to
the processes being constructed: 
  

	 	1)	Anhydrous Ammonia and Solutions greater than 44% ammonia content (ammonia plant and OSBL facilities containing ammonia) 

	 	2)	 Nitric acid at concentration equal to or greater than 94.5% (nitric acid concentration NACSAC® process and related OSBL facilities containing the concentrated nitric acid) 

 

	 	3)	 Nitric Oxides in portions of the nitric acid NACSAC® concentration process and the Weatherly “DMW2” regular nitric acid process. 

 Although these materials will not be in the processes through the mechanical completion phase, any design performed by the contractor shall conform to these OSHA 29 CFR 1910.119 design and construction
requirements. 
 Environmental Regulations 
 The Work must comply with all regulations of the U.S. Environmental Protection Agency (EPA) and the Arkansas Department of Environmental Quality (ADEQ). No construction activity deemed by EPA and ADEQ as
a Site improvement may begin until the ADEQ has issued a construction permit. Purchase and staging of construction materials and equipment, Site preparation such as demolition and re-grading and mobilization of the construction organization to the
Site are allowed prior to the issuance of the construction permit. The project must conform to all requirements of the final permit. 
 Other
areas of environmental compliance for the Work may include, but are not limited to: 
  

	 	•	 	 Storm Water Run-Off: The Site has a National Pollutant Discharge Elimination System (NPDES) permit. Any work that may include a change in storm water
run-off, erosion or sediment control must be approved by the Owner. 

  

	 	•	 	 Dredged and Fill Material: Dredged material (i.e., material that is dredged or excavated from waters of the United States) or fill material (i.e.,
material that replaces an aquatic area with dry land or changes the bottom elevation of a water body) requires a permit under Section 404 of the Clean Water Act. 

 

	 	•	 	 Solid and Hazardous Wastes: Examples of materials at construction sites that may be classified as hazardous wastes include: spent cleaners (e.g.,
organic solvents), paints (including lead-based paint), used oil, paint thinners, wastes that contain ignitable and corrosive materials and wastes that contain certain toxic pollutants. A list of hazardous wastes and their allowed concentrations is
in the regulations that implement the Resource Conservation and Recovery Act (RCRA). These regulations also contain requirements for managing, treating, and disposing of hazardous wastes. 

 

	 	•	 	 Lead-Based Paints: If there are any lead-based paints (LBP) encountered during the Work, EPA regulations may apply. Persons who are involved in
lead-abatement projects or who perform certain lead-based paint activities shall be certified to do the work under 40 CFR Part 745 or an authorized state program, and the work has to be done in accordance with work practice standards in 40 CFR Part
745. 

  

	 	•	 	 Waste Disposal: Collecting, storing and transporting certain materials which are treated as universal waste (i.e., items such as batteries, thermostats
and fluorescent lamps that contain mercury etc.) must follow the Site procedures and RCRA requirements for recycling, treatment, or disposal of the wastes. Construction and Demolition (C&D) wastes such as wood, roof material, insulation,
plaster, or sheet rock that end up in either a municipal solid waste landfill or a landfill devoted exclusively to C&D wastes are subject to Site and ADEQ/EPA’s landfill criteria. 

  
 2 

	 	•	 	 Storage Tanks for Petroleum Products: Materials such as gas or diesel fuel may be subject to the requirements of either RCRA, the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA), or the Oil Pollution Act, which dictate how to store, label, and dispose of these materials, and plan for spill prevention. 

 

	 	•	 	 Spill Reporting: Emergency planning and reporting requirements for hazardous chemicals under the Emergency Planning and Community Right-to-Know Act
(EPCRA) and for oil under the Oil Pollution Act depend on the material handled. If there is a spill or release of more than a reportable quantity by the EPC Contactor or its subcontractors on the Site, it must be immediately reported to Owner and
the proper authority. EPCRA also requires that EPC Contactor or its subcontractors maintain a material safety data sheet (MSDS) for all materials on the construction site that contain hazardous chemicals. 

 

	 	•	 	 Excavated Soils (Superfund Liability): If excavated soils contain a hazardous substance under CERCLA rules, it must be immediately reported to
Owner’s management for determination of proper handling. 

  

	 	•	 	 PCB Wastes: Any polychorinated biphenol (PCB) wastes (e.g., fluorescent light ballasts containing PCBs in the potting material, old transformers that
contain PCBs) during C&D activity of the Work must be immediately reported to Owner and meet requirements for storage and disposal of PCB waste under the Toxics Substances Control Act (TSCA). 

 

	 	•	 	 Clean Air Act (CAA) Requirements: Mobile and stationary sources (e.g. heavy trucks, space heaters, dust control issues) may be subject to requirements
of the CAA. 

  

	 	•	 	 Asbestos: If the combined amount of regulated Asbestos-Containing Material (RACM) demolish or renovate a facility (i.e., a material that contains
greater than one percent asbestos) in the facility is at least 260 linear feet of pipe, 160 square feet of other facility components, or 35 cubic feet of facility components when the length or area cannot be measured, the National Emission Standard
for Hazardous Air Pollutants (NESHAP) for asbestos shall be met. It requires, among other things, that EPA be notified when a facility is demolished. When a facility is renovated, EPA has to be notified only if the renovated facility contains the
above combined amount of RACM. Asbestos also is a hazardous substance when it is in a form that can be reduced to dust by hand pressure (i.e., it is friable). If friable asbestos is present at the construction site, it may be subject to requirements
under CERCLA. 

 Security 
 The Site is regulated by the U.S. Department of Home Security (DHS) under the Chemical Facility Antiterrorism Standards (CFATS) and must follow certain Risk-Based Performance Standards (RBPS). Some of the
requirements include: 
  

	 	•	 	 RBPS 3 – Screen and Control Access, is focused on the identification, screening, and/or inspection of individuals and vehicles as they enter and
exit the facility or restricted areas within a facility. Under this requirement the EPC Contactor, its subcontractors, drivers or other personnel passing through the controlled facility perimeter will be subject to the Owner’s requirements for
identification and badging, background checks, inspections of vehicles and containers entering or exiting the Site and compliance with applicable Site security regulations. 

  
 3 

	 	•	 	 RBPS 12 – Personnel Surety requires the chemical facility to ensure that individuals allowed on-site have passed suitable background checks. This
will apply to the EPC Contactor, its subcontractors, drivers or other personnel passing through the controlled facility perimeter. The DHS is also developing a final rule which may allow other government-issued documents which meet this requirement
such as a commercial driver’s license with a Haz-mat endorsement or a TWIC card in lieu of a separate background check. The four elements required of a background check are: 

 

	 	1.	Measures designed to verify and validate identity: This typically involves a social security/name trace search, which reveals names associated with a social security
number, past and present addresses, and fraudulent use of social security numbers. Results may also be used to cross-reference addresses supplied by the applicant to ensure the integrity of the information on the job application or resume.

  

	 	2.	Measures designed to check criminal history: This typically involves a search of publicly or commercially available databases, such as county, state, and/or Federal
criminal record repositories for jurisdictions in which an individual has worked or resided. A typical criminal history search would uncover any criminal charges, outstanding warrants, dates, sentencing, and disposition for felonies and/or
misdemeanors. I n conducting or evaluating such a search, a facility may wish to consult the federally established list of disqualifying crimes applicable to hazmat drivers and transportation workers at ports (see 49 CFR § 1572.103). A second
type of search that often is used to check criminal history is a national criminal scan. A national scan serves as a supplement to criminal history searches by searching to identify criminal activity in jurisdictions outside of the geographical
locations of current and previous residence and employment. 

  

	 	3.	Measures designed to verify and validate legal authorization to work: The standard way to validate legal authorization to work is through the filing of U.S. Citizenship
and Immigration Services (USCIS) Form I-9: Employment Eligibility Verification or through DHS’s E-Verify program. 

  

	 	4.	Measures designed to identify people with terrorist ties: Because information regarding terrorist ties is not publicly available, DHS is in the process of developing a
system through which regulated facilities will be able to have relevant individuals screened by DHS through the Terrorist Screening Database (TSDB). When this system is in place the EPC Contactor and Owner will agree to a system to meet this
requirement. 

  
 4 

 A person without the required background check must be continuously accompanied by a vetted individual with
a secure background check and authorized by the Owner. Use of this option will be restricted by the Owner, and whenever possible persons working inside the Site security perimeter must have a background check before working on the Site.
