ARTICLE I

SCOPE OF SUPPLEMENTAL INDENTURE; GENERAL; THE NOTES

SECTION 1.1. Scope of Supplemental Indenture; General. This Supplemental Indenture supplements, and to the extent inconsistent therewith, replaces, the provisions of the Base Indenture, to which provisions reference is hereby made.

The changes, modifications and supplements to the Base Indenture effected by this Supplemental Indenture shall be applicable only with respect to, and govern the terms of, and shall be deemed expressly included in this Supplemental Indenture solely for the benefit of, the Notes (which shall be initially in the aggregate principal amount of $750,000,000) and shall not apply to any other Series of Securities that have or may be issued under the Indenture unless a supplemental indenture with respect to such other Series of Securities specifically incorporates such changes, modifications and supplements.

SECTION 1.2. Applicability of Sections of the Base Indenture. Except as expressly specified hereby, each of the provisions of the Base Indenture shall apply to the Notes.

SECTION 1.3. Form, Dating and Terms.

(a) The aggregate principal amount of Notes that may be authenticated and delivered under the Indenture is unlimited. The aggregate principal amount of the Initial Notes initially authorized for authentication and delivery pursuant to this Supplemental Indenture is limited to $750,000,000 (except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 1.3(c), 1.3(d), 4.2(c) and 8.6 of this Supplemental Indenture and Sections 2.7, 2.8, 2.11 and 3.6 of the Base Indenture). Pursuant to this Supplemental Indenture, there is hereby created and designated a Series of Securities under the Base Indenture entitled “4.375% Senior Notes due 2024.”

In addition, the Company may issue, from time to time subsequent to the Issue Date in accordance with the provisions of the Indenture, additional notes (such notes, the “Additional Notes” and together with the Initial Notes, the “Notes”) of the same Series as the Notes and the guarantee thereof by the Subsidiary Guarantors.

The Initial Notes and the Additional Notes shall be considered collectively as a single class for all purposes of the Indenture. Holders of the Initial Notes and the Additional Notes shall vote and consent together on all matters to which such Holders are entitled to vote or consent as one Series of Securities, and none of the Holders of the Initial Notes or the Additional Notes shall have the right to vote or consent as a separate class or series on any matter to which such Holders are entitled to vote or consent.

Initial Notes and Additional Notes shall be initially issued in the form of one or more permanent Registered Global Securities substantially in the form of Exhibit A (each, a “Global Note”), duly executed by the Company and authenticated by the Trustee as provided in the Base Indenture. The aggregate principal amount of the Global Notes may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee.

Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Supplemental Indenture or the Base Indenture or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

The terms and provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this Supplemental Indenture and the Company, the Subsidiary Guarantors and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

The Notes shall be guaranteed by the Subsidiary Guarantors as provided in this Supplemental Indenture. The Company shall pay principal of, premium, if any, and interest on the Notes in money of the United States that at the time of payment is legal tender for payment

of public and private debts. Payments on the Notes shall be payable at the office or agency of the Company maintained for such purpose in the Borough of Manhattan, The City of New York. Payments in respect of Notes represented by a Global Note registered in the name of or held by the Depositary or its nominee (including principal, premium, if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by the Depositary. The Company shall make all payments in respect of a Definitive Note (including principal, premium, if any, and interest) by mailing a check to the registered address of each Holder thereof as such address shall appear on the in the Registrar’s books; provided, however, that payments on the Notes represented by Definitive Notes may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Notes represented by Definitive Notes, by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 15 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept).

If any scheduled date for a payment on the Notes is not a Business Day, then the payment will be paid on the next succeeding Business Day without additional interest in respect of such delay.

(b) Denominations. The Notes shall be issuable only in fully registered form, without coupons, and only in denominations of $2,000 or integral multiples of $1,000 in excess thereof.

(c) Book-Entry Provisions. The provisions of this Section 1.3(c) and Section 1.4(d) below will apply to the Notes in lieu of the provisions of Section 2.14 of the Base Indenture.

(i) This Section 1.3(c) shall apply only to Global Notes deposited with the Notes Custodian with respect to such Notes (as appointed by the Depositary), or any successor Person thereto, which shall initially be the Trustee.

(ii) Each Global Note initially shall (x) be registered in the name of the Depositary for such Global Note or the nominee of such Depositary, (y) be delivered to the Notes Custodian for such Depositary and (z) bear the legend set forth in Exhibit A.

(iii) Members of, or participants in, the Depositary (“Agent Members”) shall have no rights under the Indenture with respect to any Global Note held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Note, and the Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of customary practices of the Depositary governing the exercise of the rights of a Holder of a beneficial interest in any Global Note.

(iv) The registered Holder of a Global Note may grant proxies and otherwise authorize any person, including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under the Indenture or the Notes.

(v) In connection with the transfer of an entire Global Note to beneficial owners pursuant to Section 1.3(d) of this Supplemental Indenture, such Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depositary in exchange for its beneficial interest in such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations.

(vi) Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interests in such Global Note may be effected only through a book-entry system maintained by (a) the Holder of such Global Note (or its agent) or (b) any Holder of a beneficial interest in such Global Note, and that ownership of a beneficial interest in such Global Note shall be required to be reflected in a book entry.

(d) Definitive Notes. Except as provided in the Indenture, owners of beneficial interests in Global Notes shall not be entitled to receive Definitive Notes. Definitive Notes shall be delivered to all beneficial owners in exchange for their beneficial interests in a Global Note if (i) the Depositary notifies the Company that it is unwilling or unable to continue as depositary for such Global Note or 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 in order to act as Depositary, and in each case a successor depositary is not appointed by the Company within 90 days of such notice or (ii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depositary to deliver Definitive Notes to all beneficial owners in exchange for their beneficial interests in such Global Note.

(e) The Initial Notes may forthwith be executed by the Company and delivered, together with a Company Order, to the Trustee for authentication and delivery by the Trustee for original issue in accordance with the provisions of Section 2.3 of the Base Indenture.

(f) At any time and from time to time after the issuance of the Initial Notes, the Trustee shall authenticate and deliver any Additional Notes for original issue in accordance with the provisions of Section 2.3 of the Base Indenture in an aggregate principal amount determined at the time of issuance and specified in a Company Order which shall be accompanied with the Officers’ Certificate (and, if applicable, Board Resolution) in respect

thereof specified in Section 1.8 of this Supplemental Indenture. Such Company Order shall specify the principal amount of the Additional Notes to be authenticated and the date on which the original issue of such Additional Notes is to be authenticated.

With respect to any Additional Notes, there shall be set forth or determined in an Officers’ Certificate delivered to the Trustee or established in one or more indentures supplemental to this Supplemental Indenture, prior to the issuance of such Additional Notes:

SECTION 4.2. Change of Control.

(a) If a Change of Control occurs and is accompanied by a Ratings Decline of the Notes (together, a “Change of Control Triggering Event”), unless the Company has exercised its right to redeem all of the Notes pursuant to Section 3.1 of this Supplemental Indenture, each Holder will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

(1) that a Change of Control Triggering Event has occurred or will occur and that such Holder has the right to require the Company to purchase such

Holder’s Notes at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant interest payment date) (the “Change of Control Payment”);

(1) default in any payment of interest on any Note when due, continued for 30 days;

(A) is caused by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (“payment default”); or

(B) results in the acceleration of such Indebtedness prior to its maturity (the “cross acceleration provision”);

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there is an outstanding uncured payment default or the maturity of which has been and remains so accelerated, aggregates $50.0 million or more;

(6) the Company or a Subsidiary Guarantor, pursuant to or within the meaning of any Bankruptcy Law:

(A) commences a voluntary case or voluntary proceeding;

(B) consents to the entry of a judgment, decree or order for relief against it in an involuntary case or involuntary proceeding;

(b) Notwithstanding Section 6.1(a), a default under Section 6.1(a)(4) will not constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the then outstanding Notes notify the Company in writing of the default and the Company does not cure such default within the time specified in Section 6.1(a)(4) after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.””

SECTION 6.2. Acceleration of Maturity; Rescission and Annulment. Solely with respect to the Notes, Section 6.2 of the Base Indenture is hereby amended and restated as follows:

“If an Event of Default (other than an Event of Default described in Section 6.1(a)(6) or (7)) occurs and is continuing, the Trustee by written notice to the Company, or the Holders of at least 25% in principal amount of the then outstanding Notes by written notice to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare the principal, premium, if any, and accrued and unpaid interest, if any, on all the Notes to be due and payable. Such notice must specify the Event of Default and state that such notice is a “Notice of Acceleration.” Upon such a declaration, such principal, premium, if any, and accrued and unpaid interest will be due and payable immediately.

In the event of a declaration of acceleration of the Notes because an Event of Default described in Section 6.1(a)(5) has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically annulled if the default triggering such Event of Default pursuant to Section 6.1(a)(5) shall be remedied or cured by the Company or a Subsidiary or waived by the Holders of the relevant Indebtedness within 20 days after the written notice of declaration of acceleration of the Notes with respect thereto is received by the Company and if (1) the annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction and (2) all, existing Events of Default, except nonpayment of principal, premium, if any, or interest on the Notes that became due solely because of the acceleration of the Notes, have been cured or waived.

If an Event of Default pursuant to Section 6.1(a)(6) or (7) occurs and is continuing, the principal, premium, if any, and accrued and unpaid interest on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders.

At any time after a declaration of acceleration, but before a judgment or decree for the payment of the money due has been obtained by the Trustee, the Holders of a majority in principal amount of the outstanding Notes by notice to the Trustee and the Company (including, without limitation, waivers and consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) may rescind and annul such declaration of acceleration and its consequences; provided, that (i) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing Events of Default, other than nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived.”

SECTION 6.3. Limitation on Suits. Solely with respect to the Notes, Section 6.7 of the Base Indenture is hereby amended and restated as follows:

“Subject to Section 7.1 of the Base Indenture, if an Event of Default occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect to the Indenture or the Notes unless:

(1) such Holder has previously given the Trustee notice that an Event of Default is continuing;

(2) Holders of at least 25% in principal amount of the then outstanding Notes have requested the Trustee to pursue the remedy;

(3) such Holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

(4) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity; and

(5) the Holders of a majority in principal amount of the then outstanding Notes have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60 day period.”

SECTION 6.4. Control by Majority. Solely with respect to the Notes, Section 6.12 of the Base Indenture is hereby amended and restated as follows:

“The Holders of a majority in principal amount of the outstanding Notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. In the event an Event of Default has occurred and is continuing, the Trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use under the circumstances in the conduct of its own affairs. The Trustee, however, may refuse to follow any direction that conflicts with law, the Indenture, the Notes or any Subsidiary Guarantee, or that the Trustee determines in good faith is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability. Prior to taking any action under the Indenture, the Trustee will be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action.”

SECTION 6.5. Collection Suit by Trustee. Solely with respect to the Notes, Section 6.3 of the Base Indenture is hereby amended and restated as follows:

“If an Event of Default specified in clauses (1) or (2) of Section 6.1(a) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.7 of the Base Indenture.”

and the Company or any Subsidiary Guarantor, in the case of (i), (ii) or (iii) above, has irrevocably deposited or caused to be deposited with such Trustee, as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, as confirmed, certified or attested by an accounting, appraisal, investment banking firm or consultant selected by the Company, without consideration of any reinvestment of interest, to pay and discharge the entire Indebtedness on the Notes not theretofore delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption, as the case may be;

(2) the Company or any Subsidiary Guarantor has paid or caused to be paid all sums payable by the Company under the Indenture;

(3) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or the redemption date, as the case may be; and

(4) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary assumptions and exclusions) each stating that all conditions precedent to satisfaction and discharge have been satisfied.

Notwithstanding the satisfaction and discharge of this Supplemental Indenture and the Base Indenture (as it relates to the Notes), the obligations of the Company to the Trustee under Section 7.7 of the Base Indenture, the obligations of the Trustee or the Company to any

authenticating agent under the Indenture and, if money shall have been deposited with the Trustee pursuant to Section 7.1(1)(B) of this Supplemental Indenture, the rights and obligations referred to in Section 7.2(a)(1) and (2) below and the obligations of the Trustee under Section 6.6 of the Base Indenture, the last paragraph of Section 4.7 of the Base Indenture and Section 7.5 of the Base Indenture shall survive such satisfaction and discharge.

SECTION 7.2. Legal Defeasance.

(a) Subject to Section 7.4 of this Supplemental Indenture, the Company may, at its option and at any time, elect to have all of its obligations under the Notes, this Supplemental Indenture and the Base Indenture (as it relates to the Notes) and all obligations of the Subsidiary Guarantors under the Subsidiary Guarantees and the Base Indenture (as it relates to the Notes) discharged with respect to the outstanding Notes issued under this Supplemental Indenture (“legal defeasance”). For this purpose, legal defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.2 of the Base Indenture and the other Sections of the Indenture referred to in (1) and (2) below, and to have satisfied all of its other obligations under such Notes, the Supplemental Indenture and the Indenture (as it relates to the Notes) (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders to receive payments in respect of the principal, premium, if any, and interest on the Notes when such payments are due, solely out of the trust referred in Section 7.4 of this Supplemental Indenture;

(2) the Company’s obligations with respect to the Notes under Article 2 of the Base Indenture concerning issuing temporary Notes, registration of Notes, mutilated, destroyed, lost or stolen Notes and Sections 2.4 and 2.7 of the Base Indenture concerning the maintenance of an office or agency for payment and money for Note payments held in trust;

(3) the rights, powers, trusts, duties and immunities of the Trustee, and the Company’s obligations in connection therewith; and

(4) the provisions of this Section 7.2.

(b) If the Company exercises the legal defeasance option, the Subsidiary Guarantees in effect at such time will be automatically released.

(c) If the Company exercises its legal defeasance option, payment of the Notes may not be accelerated because of an Event of Default with respect to the Notes.

(d) The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option as set forth in Section 7.3 of this Supplemental Indenture.

SECTION 7.3. Covenant Defeasance.

(a) Subject to Section 7.4 of this Supplemental Indenture, the Company and the Subsidiary Guarantors at any time may terminate their obligations under Sections 4.1, 4.2, 4.3 and 4.4 of this Supplemental Indenture and Section 4.5 of the Base Indenture and the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere in the Indenture to any such covenant or by reason of any reference in any such covenant to any other provision in the Indenture or in any other document and such omission to comply with such covenants shall no longer constitute a Default or an Event of Default under Section 6.1(a)(4) of this Supplemental Indenture (“covenant defeasance”).

(b) If the Company exercises its covenant defeasance option, payment of the Notes may not be accelerated because of, and a Default or Event of Default shall no longer be deemed to exist as a result of or to arise out of, an Event of Default specified in Sections 6.1(a)(4) (as such clause relates to Sections 4.1, 4.2, 4.3 and 4.4 of this Supplemental Indenture and Section 4.5 of the Base Indenture), Section 6.1(a)(5), Section 6.1(a)(6) (with respect to only Subsidiary Guarantors) or Section 6.1(a)(7) (with respect only to Subsidiary Guarantors).

(c) If the Company exercises the covenant defeasance option, the Subsidiary Guarantees in effect at such time will be automatically released.

SECTION 7.4. Conditions to Legal Defeasance or Covenant Defeasance. The following shall be the conditions to the exercise of either legal defeasance or covenant defeasance with respect to the outstanding Notes:

(1) the Company shall have irrevocably deposited in trust (the “defeasance trust”) with the Trustee money or U.S. Government Obligations for the payment of principal, premium, if any, and interest on the Notes to redemption or maturity, as the case may be;

(2) the Company shall have delivered to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion (or if nationally recognized independent accounting firms no longer routinely express such opinions, a certificate from the chief financial officer of the Company expressing his or her opinion) that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment shall provide cash at such times and in such amounts as shall be sufficient to pay principal, premium, if any, and interest when due on all the Notes to maturity or redemption, as the case may be;

(3) no Event of Default shall have occurred and be continuing on the date of such deposit (other than Events of Default arising out of the incurrence of Liens on Funded Debt all or a portion of the proceeds of which are to be used to fund such deposit);

(4) such legal defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, the Indenture (insofar as it relates to any Series of Securities other than the Notes) or any other material agreement or

instrument to which the Company is a party or by which the Company is bound (other than the Indenture);

(5) in the case of legal defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling, or (ii) since the date of the Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders shall not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and shall be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred;

(6) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an Opinion of Counsel (subject to customary assumptions and exclusions) in the United States to the effect that the Holders shall not recognize income, gain or loss for Federal income tax purposes as a result of such deposit and Covenant Defeasance and shall be subject to Federal income tax on the same amount, in the same manner and at the same times as would have been the case if such deposit and Covenant Defeasance had not occurred; and

(7) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, together stating that all conditions precedent to the covenant defeasance or legal defeasance with respect to the Notes as set forth in this Section 7.4 have been complied with.

Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the discharge of those obligations that the Company terminates.

Notwithstanding the provisions of Sections 7.2, 7.3 and 7.4 of this Supplemental Indenture, the Company’s obligations in Sections 2.4, 2.5, 2.6, 2.7, 7.1, 7.2, 7.7, 7.8 of the Base Indenture, Section 7.5 of this Supplemental Indenture, and Sections 8.2 and 8.5 of the Base Indenture shall survive until the Notes have been paid in full. Thereafter, the Company’s and the Subsidiary Guarantors’ obligations in Sections 7.7, 8.2 and 8.5 of the Base Indenture shall survive.

SECTION 7.5. Reinstatement. If the Trustee or Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article VII by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Company under this Supplemental Indenture, the Base Indenture (as it relates to the Notes) and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article VII until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article VII; provided, however, that, if the Company has made any payment of interest on or principal of any Notes because of the

reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or Paying Agent.

ARTICLE VIII

AMENDMENT, SUPPLEMENT AND WAIVER

Article 9 of the Base Indenture shall not apply to the Notes, provided that nothing in this Supplemental Indenture shall limit or affect the provisions of Article 9 of the Base Indenture (including Sections 9.1(f) and 9.1(k) thereof) insofar as relating to any amendment or waiver in respect of any Series of Securities other than the Notes.

SECTION 8.1. Without Consent of Holders. Notwithstanding Sections 8.2 and 8.3, without the consent of any Holder of Notes, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes and the Subsidiary Guarantees to:

(1) cure any ambiguity, omission, defect or inconsistency;

(2) provide for the assumption by a successor entity of the obligations of the Company or any Subsidiary Guarantor under this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes or the Subsidiary Guarantees in accordance with Article V;

(3) provide for or facilitate the issuance of uncertificated Notes in addition to or in place of certificated Notes (provided that the uncertificated Notes are issued in registered form for purposes of Section 163(f) of the Code or in a manner such that the uncertificated Notes are described in Section 163(f) (2) (B) of the Code);

(4) add Guarantees with respect to the Notes in accordance with the applicable provisions of the Indenture;

(5) release a Subsidiary Guarantor from its obligations under its Subsidiary Guarantee or this Supplemental Indenture and the Base Indenture (as it relates to the Notes) in accordance with the applicable provisions of the Indenture;

(6) secure the Notes and the Subsidiary Guarantees;

(7) add covenants of the Company, any Subsidiary Guarantor or other obligor under this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes or the Subsidiary Guarantees, as the case may be, or Events of Default for the benefit of the Holders of the Notes or to make changes that would provide additional rights to the Holders of the Notes or to surrender any right or power conferred upon the Company, any Subsidiary Guarantor or other such obligor;

(8) make any change that does not adversely affect the legal or contractual rights of any Holder under this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes or the Subsidiary Guarantees;

(9) evidence and provide for the acceptance of an appointment under this Supplemental Indenture or the Base Indenture (as it relates to the Notes) of a successor trustee; provided that the successor trustee is otherwise qualified and eligible to act as such under the terms of the Indenture;

(10) provide for the issuance of Additional Notes permitted to be issued under this Supplemental Indenture and the Base Indenture (as it relates to the Notes);

(11) comply with the rules of any applicable securities depositary; or

(12) conform the text of this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes or the Subsidiary Guarantees to any provision of the section of the Company’s Prospectus Supplement dated May 20, 2014 entitled “Description of Notes” to the extent that such provision in the “Description of Notes” was intended to be a verbatim recitation of a provision of the Indenture (as it relates to the Notes), the Notes or the Subsidiary Guarantees.

After an amendment, supplement or waiver under the Indenture becomes effective, the Company is required to mail to the Holders a notice briefly describing such amendment, supplement or waiver. However, the failure to give such notice to all the Holders, or any defect in the notice will not impair or affect the validity of any amendment, supplement or waiver.

SECTION 8.2. With Consent of Holders. Except as set forth in Sections 8.1 and 8.3, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes and the Subsidiary Guarantees with the consent of the Holders of a majority in principal amount of the Notes then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes) and any past default or compliance with any provisions of this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes and the Subsidiary Guarantees may be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes).

The consent of the Holders is not necessary under the Indenture to approve the particular form of any proposed amendment, supplement or waiver. It is sufficient if such consent approves the substance of the proposed amendment or supplement. A consent to any amendment, supplement or waiver under the Indenture by any Holder of Notes given in connection with a tender of such Holder’s Notes will not be rendered invalid by such tender. After an amendment, supplement or waiver under the Indenture becomes effective, the Company is required to mail to the Holders a notice briefly describing such amendment, supplement or waiver. However, the failure to give such notice to all the Holders, or any defect in the notice will not impair or affect the validity of any amendment, supplement or waiver.

SECTION 8.3. Limitations. Notwithstanding Section 8.2, without the consent of each Holder of an outstanding Note affected, no amendment, supplement or waiver may (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the stated rate of interest or extend the stated time for payment of interest on any Note;

(3) reduce the principal of or extend the Stated Maturity of any Note;

(4) waive a Default or Event of Default in the payment of principal of, premium, if any, or interest on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes with respect to a nonpayment default and a waiver of the payment default that resulted from such acceleration);

(5) reduce the premium payable upon the redemption or repurchase of any Note or change the time at which any Note may be redeemed or repurchased as described under Section 4.2 or Article III, whether through an amendment or waiver of Section 4.2, Article 3, related definitions or otherwise (except amendments to the definitions of “Change of Control” or “Change of Control Triggering Event”);

(6) make any Note payable in money other than that stated in the Note;

(7) impair the right of any Holder to receive payment of principal, premium, if any, and interest on such Holder’s Notes on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Notes;

(8) make any change in the amendment or waiver provisions which require each Holder’s consent; or

(9) modify the Subsidiary Guarantees in any manner adverse to the Holders of the Notes.

SECTION 8.4. Compliance with Trust Indenture Act. Every amendment to this Supplemental Indenture, the Base Indenture (as it relates to the Notes), the Notes or the Subsidiary Guarantees shall be set forth in a supplemental indenture hereto that complies with the TIA as then in effect.

SECTION 8.5. Revocation and Effect of Consents. Until an amendment or waiver becomes effective, a consent to it by a Holder of Notes is a continuing consent by the Holder and every subsequent Holder of the Notes or portion of such Notes that evidences the same debt as the consenting Holder’s Note or Notes, even if notation of the consent is not made on any such Note. However, any such Holder or subsequent Holder may revoke the consent as to his Notes or portion of such Notes if the Trustee receives the notice of revocation before the date the amendment or waiver becomes effective.

Any amendment or waiver once effective shall bind every Holder of Notes affected by such amendment or waiver unless it is of the type described in any of the clauses of

Section 8.3. In that case, the amendment or waiver shall bind each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Securityholders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Supplemental Indenture or the Base Indenture (as it relates to the Notes). If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders of Notes at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders of Notes after such record date.

SECTION 8.6. Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment or waiver on the Notes. The Company in exchange for the Notes may issue and the Trustee shall authenticate upon written request new Notes that reflect the amendment or waiver.

SECTION 8.7. Trustee Protected. The Trustee shall sign any amendment, supplement or waiver authorized pursuant to this Article VIII if the amendment, supplement or waiver does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing any amendment, supplement or waiver the Trustee shall be entitled to receive indemnity reasonably satisfactory to it and to receive, and (subject to Sections 7.1 and 7.2 of the Base Indenture) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this Supplemental Indenture and that such amendment, supplement or waiver is the legal, valid and binding obligation of the Company and any Subsidiary Guarantors, enforceable against them in accordance with its terms, subject to customary exceptions.

SECTION 8.8. Effect of Supplemental Indenture. Upon the execution of any supplemental indenture under this Article VIII, the Indenture (including this Supplemental Indenture) shall be modified in accordance therewith, and such supplemental indenture shall form a part of the Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby.

ARTICLE IX

SUBSIDIARY GUARANTEES; RELEASES OF SUBSIDIARY GUARANTEES

SECTION 9.1. Subsidiary Guarantees. The Subsidiary Guarantors hereby, jointly and severally, unconditionally guarantee on a senior unsecured basis and as primary obligor and not merely as surety to each Holder and the Trustee the full and punctual payment when due, whether at maturity, by acceleration, by redemption or otherwise, of the principal of, premium, if any, and interest on the Notes and all other obligations and liabilities of the Company under this Supplemental Indenture and the Base Indenture (as it relates to the Notes) (including without limitation interest accruing after the filing of any petition in bankruptcy, or

the commencement of any insolvency, reorganization or like proceeding, relating to the Company or any Subsidiary Guarantor whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) (all the foregoing being hereinafter collectively called the “Obligations”). Each Subsidiary Guarantor further agrees (to the extent permitted by law) that the Obligations may be extended, renewed or increased (including in connection with the issuance of Additional Notes) in whole or in part, without notice or further assent from it, and that it shall remain bound under this Article IX notwithstanding any extension or renewal of any Obligation.

To evidence its Subsidiary Guarantee set forth in this Section 9.1, each Subsidiary Guarantor hereby agrees that this Supplemental Indenture (or a supplemental indenture to the Base Indenture in substantially the form of Exhibit B to this Supplemental Indenture) shall be executed on behalf of such Subsidiary Guarantor by an Officer of such Subsidiary Guarantor. The Subsidiary Guarantee of any Subsidiary Guarantor shall be evidenced solely by its execution and delivery of this Supplemental Indenture (or, in the case of any Subsidiary Guarantor that is not party to this Supplemental Indenture on the Issue Date, a supplemental indenture hereto in substantially the form of Exhibit B hereto) and not by an endorsement on, or attachment to, any Note or any Guarantee or notation thereof. Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set forth in this Section 9.1 shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Subsidiary Guarantee on the Notes. If an Officer whose signature is on this Supplemental Indenture or another indenture supplement to the Base Indenture no longer holds that office at the time the Trustee authenticates the Note, the Subsidiary Guarantee shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantee set forth in this Supplemental Indenture on behalf of the Subsidiary Guarantors.

Each Subsidiary Guarantor waives presentation to, demand of payment from and protest to the Company of any of the Obligations and also waives notice of protest for nonpayment. Each Subsidiary Guarantor waives notice of any default under the Notes or the Obligations. The obligations of each Subsidiary Guarantor hereunder shall not be affected by (a) the failure of any Holder to assert any claim or demand or to enforce any right or remedy against the Company or any other person under the Indenture, the Notes or any other agreement or otherwise; (b) any extension or renewal of any thereof; (c) any rescission, waiver, amendment or modification of any of the terms or provisions of the Indenture, the Notes or any other agreement; (d) the release of any security held by any Holder or the Trustee for the Obligations or any of them; (e) the failure of any Holder to exercise any right or remedy against any other Subsidiary Guarantor; or (f) any change in the ownership of the Company.

Each Subsidiary Guarantor further agrees that its Guarantee herein constitutes a Guarantee of payment when due (and not a Guarantee of collection) and waives any right to require that any resort be had by any Holder to any security held for payment of the Obligations.

The obligations of each Subsidiary Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (other than payment of the Obligations in full), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability of the Obligations or

otherwise. Without limiting the generality of the foregoing, the obligations of each Subsidiary Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder to assert any claim or demand or to enforce any remedy under the Indenture, the Notes or any other agreement, by any waiver or modification of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the Obligations, or by any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Subsidiary Guarantor or would otherwise operate as a discharge of such Subsidiary Guarantor as a matter of law or equity.

Each Subsidiary Guarantor agrees that its Guarantee herein shall remain in full force and effect until payment in full of all the Obligations or such Subsidiary Guarantor is released from its Guarantee in compliance with Section 9.2 or otherwise in accordance with the terms of the Indenture. Each Subsidiary Guarantor further agrees that its Guarantee herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal of or interest on any of the Obligations is rescinded or must otherwise be restored by any Holder upon the bankruptcy or reorganization of the Company or otherwise.

In furtherance of the foregoing and not in limitation of any other right which any Holder has at law or in equity against any Subsidiary Guarantor by virtue hereof, upon the failure of the Company to pay any of the Obligations when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, the Subsidiary Guarantors hereby jointly and severally promise to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders an amount equal to the sum of (i) the unpaid amount of such Obligations then due and owing and (ii) accrued and unpaid interest on such Obligations then due and owing (but only to the extent not prohibited by law).

Each Subsidiary Guarantor further agrees that, as between such Subsidiary Guarantor, on the one hand, and the Holders, on the other hand, (x) the maturity of the Obligations guaranteed hereby may be accelerated as provided in the Indenture for the purposes of its Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the Obligations guaranteed hereby and (y) in the event of any such declaration of acceleration of such Obligations, such Obligations (whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantor for the purposes of this Guarantee.

Each Subsidiary Guarantor also agrees to pay any and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or the Holders in enforcing any rights under this Section 9.1.

SECTION 9.2. Limitation on Liability; Termination, Release and Discharge.

(a) The obligations of each Subsidiary Guarantor will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor (including, without limitation, any Guarantees under Revolving Credit Agreement) and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its contribution obligations under the Indenture,

result in the obligations of such Subsidiary Guarantor under its Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law and not otherwise being void or voidable under any similar laws affecting the rights of creditors generally.

(b) In the event a Subsidiary Guarantor is sold or disposed of (whether by merger, consolidation, the sale of its Capital Stock or the sale of all or substantially all of its assets (other than by lease) and whether or not the Subsidiary Guarantor is the surviving corporation in such transaction) to a Person which is not the Company or a Subsidiary of the Company (after giving effect to the merger, consolidation, sale or other disposition), such Subsidiary Guarantor will be released from its obligations under this Supplemental Indenture, the Base Indenture (as it relates to the Notes) and its Subsidiary Guarantee if all the obligations of such Subsidiary Guarantor under the Revolving Credit Agreement and any other agreements evidencing any other Indebtedness of the Company or its other Subsidiaries (after giving effect to the merger, consolidation, sale or other disposition) terminate upon consummation of such transaction.

(c) A Subsidiary Guarantor will be released from its obligations under this Supplemental Indenture, the Base Indenture (as it relates to the Notes) and its Subsidiary Guarantee in connection with any legal defeasance or covenant defeasance of the Notes or upon satisfaction and discharge of the Indenture pursuant to the provisions of Article VII, each in accordance with the terms of this Supplemental Indenture.

(d) In the event a Subsidiary Guarantor is released and discharged in full from all of its obligations under its Guarantees (except a release or discharge by or as a result of payment under such Guarantee) of (1) the Revolving Credit Agreement and (2) all other Indebtedness of the Company or any other Subsidiary Guarantor in excess of $25.0 million, then the Subsidiary Guarantor will be released from its obligations under this Supplemental Indenture, the Base Indenture (as it relates to the Notes) and its Subsidiary Guarantee.

(e) Upon compliance with any of the conditions in Section 9.2(b), (c) or (d), the Trustee shall deliver an appropriate instrument evidencing such release and discharge upon receipt of a Company Request accompanied by an Officers’ Certificate certifying as to the compliance with this Section 9.2.

SECTION 9.3. Right of Contribution. Subject to Section 9.4 below, each Subsidiary Guarantor hereby agrees that to the extent that any Subsidiary Guarantor shall have paid more than its proportionate share of any payment made on the obligations under the Subsidiary Guarantees, such Subsidiary Guarantor shall be entitled to seek and receive contribution from and against the Company or any other Subsidiary Guarantor who has not paid its proportionate share of such payment. The provisions of this Section 9.3 shall in no respect limit the obligations and liabilities of each Subsidiary Guarantor to the Trustee and the Holders, and each Subsidiary Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such Subsidiary Guarantor hereunder.

SECTION 9.4. No Subrogation. Notwithstanding any payment or payments made by each Subsidiary Guarantor hereunder, no Subsidiary Guarantor shall be entitled to be

subrogated to any of the rights of the Trustee or any Holder against the Company or any other Subsidiary Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Obligations, nor shall any Subsidiary Guarantor seek or be entitled to seek any contribution or reimbursement from the Company or any other Subsidiary Guarantor in respect of payments made by such Subsidiary Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the Obligations are paid in full. If any amount shall be paid to any Subsidiary Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Subsidiary Guarantor in trust for the Trustee and the Holders, segregated from other funds of such Subsidiary Guarantor, and shall, forthwith upon receipt by such Subsidiary Guarantor, be turned over to the Trustee in the exact form received by such Subsidiary Guarantor (duly indorsed by such Subsidiary Guarantor to the Trustee, if required), to be applied against the Obligations.
