The Securities are to be sold to each Underwriter, acting severally and not jointly, in the respective principal amounts as are set forth in Schedule A hereto opposite the name of such Underwriter. The Securities are to be issued pursuant to an Indenture, dated as of August 19, 2014, as modified or supplemented by a First Supplemental Indenture, to be dated as of April 26, 2018 (collectively, the “Indenture”), between the Company and U.S. Bank National Association, as trustee (the “Trustee”). The Securities and the Indenture are more fully described in the Prospectus referred to below.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (Registration No. 333-220010), including the related base prospectus, which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “1933 Act Regulations”) under the Securities Act of 1933, as amended (the “1933 Act”). Such registration statement covers, among other securities, the registration of the Securities under the 1933 Act.

Any information included in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” The prospectus, dated August 17, 2017 (the “Base Prospectus”), together with the preliminary prospectus supplement, dated April 23, 2018, used in connection with the offering of the Securities, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, is herein called the “Preliminary Prospectus.” Such registration statement, at any given time, including the amendments thereto to such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act at such time and the documents otherwise deemed to be a part thereof or included therein by the 1933 Act Regulations at such time, is herein called the “Registration Statement.” The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The Base Prospectus together with the final prospectus supplement, dated April 23, 2018, in the form first furnished to the Underwriters for use in connection with the offering of the Securities, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, the Preliminary Prospectus, the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to mean and include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”) or any successor thereto.

(a) Representations and Warranties of the Company . The Company represents and warrants to and agrees with each of the Underwriters as of the Applicable Time referred to in this Section 1(a) and as of the Closing Time referred to in Section 2(b) hereof, that:

(i) Status as a Well-Known Seasoned Issuer . (A) At the time of filing the Original Registration Statement, (B) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the 1934 Act or form of prospectus), (C) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the 1933 Act Regulations) made any offer relating to the Securities in reliance on the exemption provided by Rule 163 of the 1933 Act Regulations (“Rule 163”) and (D) at the date hereof, the Company was and is a “well-known seasoned issuer,” as defined in Rule 405 of the 1933 Act Regulations (“Rule 405”). The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405, and the Securities, since their registration on the Registration Statement, have been and remain eligible for registration by the Company on a Rule 405 “automatic shelf registration statement.” The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) of the 1933 Act Regulations objecting to the use of the automatic shelf registration statement form.

At the time of filing the Original Registration Statement, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Securities and at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405.

9

In the ordinary course of business, the Company and its subsidiaries conduct periodic reviews of the effect of Environmental Laws on their assets and operations, and, on the basis of such reviews, the Company has concluded that there are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permits, licenses, consents, authorizations or other approvals, any related constraints on operating activities and any potential liabilities to third parties) in excess of reserves that have been established which would, individually or in the aggregate, have a Material Adverse Effect.

Except as described in the Preliminary Prospectus and the Prospectus, since the end of the Company’s most recent audited fiscal year, there has been (i) no material weakness in the Company’s internal control over financial reporting (whether or not remediated) and (ii) no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Section 6. Indemnification .

(a) Indemnification of the Underwriters . The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers and employees of each Underwriter and each person, if any, who controls such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of an untrue statement or alleged untrue statement of a material

24

fact contained in the Registration Statement, including the Rule 430B Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading, or arising out of an untrue statement or alleged untrue statement of a material fact contained in any Company Additional Written Communication, any Issuer Free Writing Prospectus, including, but not limited to, the Final Term Sheet, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, provided that (subject to Section 6(d) hereof) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever (including the fees and disbursements of counsel chosen by you), as reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under subparagraph (i) or (ii) above;

provided , however , that this indemnity agreement does not apply to any loss, liability, claim, damage or expense to the extent arising out of an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information, the Preliminary Prospectus, any Company Additional Written Communication, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of the Company, Directors and Officers . Each Underwriter severally agrees to indemnify and hold harmless the Company, its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity agreement contained in Section 6(a) hereof, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (including any amendment thereto), including the Rule 430B Information, any Company Additional Written Communication, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by such Underwriter through you expressly for use therein.

25

(c) Actions Against Parties; Notification . Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) hereof, counsel to the indemnified parties shall be selected by the Representatives and, in the case of parties indemnified pursuant to Section 6(b) hereof, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action and, at its option, may assume the defense thereof, with counsel reasonably satisfactory to the indemnified party; provided , however , that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case, subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.

No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse . If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) hereof effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received

26

notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. The indemnified party shall promptly reimburse the indemnifying party for all amounts advanced to it pursuant to this Section 6(d) (unless it is entitled to such amounts under Section 7 hereof) if it shall be finally judicially determined that such indemnified party was not entitled to indemnification hereunder and such loss, liability, claim, damage or expense arose out of (i) an untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the indemnified party expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information, any Company Additional Written Communication, any Issuer Free Writing Prospectus, the Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) or (ii) a fraudulent misrepresentation (within the meaning of Section 11 of the 1933 Act) by the indemnified party.

Section 7. Contribution .

If the indemnification provided for in Section 6 hereof is for any reason held to be unavailable or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and of the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount and commission received by the Underwriters, in each case, as set forth on the cover of or in the Prospectus bear to the aggregate initial public offering price of the Securities as set forth on such cover.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the

27

Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and each director, officer and employee of the Underwriters shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the aggregate principal amount of Securities set forth opposite their respective names in Schedule A hereto and not joint.

Section 8. Representations, Warranties, Indemnities and Agreements to Survive Delivery . All representations, warranties, indemnities, agreements and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain operative and in full force and effect regardless of any investigation made by or on behalf of the Company, any Underwriter or any person who controls the Company or any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and will survive delivery of and payment for the Securities.

Section 9. Termination of Agreement .

(a) Termination Generally . You may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time, (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Disclosure Package, any material adverse change in the business, operations or financial condition of the Company and its subsidiaries, considered as one enterprise, whether or not arising in the ordinary course of business, (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any outbreak of hostilities involving the United States or escalation thereof or other calamity or crisis or any change in national or international political, financial or economic conditions, in each case, the effect is such as to make it, in the judgment of the Representatives, impracticable or inadvisable

28

to market the Securities or enforce contracts for the sale of the Securities, (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or FINRA or if trading generally on the New York Stock Exchange (the “NYSE”) has been materially suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by the NYSE or by order of the Commission, FINRA or any other governmental authority, (iv) a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States or (v) if a banking moratorium has been declared by either federal, New York or North Carolina authorities.

(b) Liabilities . If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party, except to the extent provided in Section 4 hereof. Notwithstanding any such termination, the provisions of Sections 1, 6, 7, 8 and 16 hereof shall survive such termination and remain in full force and effect.

Section 10. Default by One or More of the Underwriters . If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities that it or they are obligated to purchase pursuant to this Agreement (the “Defaulted Securities”), you shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms set forth in this Agreement; if, however, the non-defaulting Underwriters have not completed such arrangements within such 36-hour period, then:

(a) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of the Securities to be purchased pursuant to this Agreement, each non-defaulting Underwriter shall be obligated, each severally and not jointly, to purchase the full amount thereof in the proportions that their respective Securities underwriting obligation proportions bear to the underwriting obligations of all non-defaulting Underwriters; or

(b) if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of the Securities to be purchased pursuant to this Agreement, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default that does not result in a termination of this Agreement, either the non-defaulting Underwriters or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for a Underwriter under this Section 10.
