Certain terms used herein are defined in Section 22 hereof.

This is to confirm the agreement between the Company and the Underwriters concerning the purchase of the Shares from the Company by the Underwriters.

1. Representations and Warranties. The Company represents and warrants to, and agrees with, the Underwriter as set forth below in this Section 1.

(a) Registration. The Company meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission an automatic shelf registration statement (file number 333-211522), as defined in Rule 405, on Form S-3, including a related Base Prospectus, for registration under the Act of the offering and sale of the Shares. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. The Company may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more Preliminary Final Prospectuses, each of which has previously been furnished to you. The Company will file with the Commission a final prospectus supplement relating to the Shares in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Act and the rules thereunder and, except to the extent the Underwriters shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in any Preliminary Final Prospectus) as the Company has advised you, prior to the Execution Time, will be included or made therein.

(b) No Material Misstatements or Omissions in Registration Statement or Prospectus. On the Effective Date, the Registration Statement did, and when the Final Prospectus is first filed (if required) in accordance with Rule 424(b) and on the Closing Date (as defined in Section 3 hereof) and on any date on which Option Shares are purchased, if such date is not the Closing Date (a “settlement date”), the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act and the Exchange Act and the respective rules thereunder; on the Effective Date and at the Execution Time, the Registration Statement did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any settlement date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of the Underwriters consists of the information described as such in Section 8 hereof.

(c) No Material Misstatements or Omissions in Disclosure Package. The Disclosure Package did not, as of the Execution Time, contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by the Underwriters specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriters consists of the information described as such in Section 8 hereof.

(d) Well-Known Seasoned Issuer; Eligible Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Shares in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)), the Company was or is (as the case may be) a “well-known seasoned issuer” as defined in Rule 405. At the earliest time after the filing of the Registration Statement that the Company or another offering participant made a bona fide offer of the Shares, the Company was not an “ineligible issuer” (as defined in Rule 405).

(e) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Company by the Underwriters specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriters consists of the information described as such in Section 8 hereof. The Company has not made any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Underwriters.

(f) Formation and Qualification. Each of the Targa Entities has been duly organized, formed or incorporated and is validly existing as a limited partnership, limited liability company or corporation, as applicable, in good standing under the laws of the jurisdiction set forth opposite its name in Schedule III attached hereto with full power and authority to own or lease its properties and to conduct its business, in each case as described in the Disclosure Package and the Final Prospectus, in all material respects. Each of the Targa Entities is duly registered or qualified to do business as a foreign limited partnership, limited liability company or corporation, as applicable, and is in good standing under the laws of each jurisdiction which requires such registration or qualification, except where the failure to be so registered or qualified would not reasonably be expected to have a Material Adverse Effect. “Material Adverse Effect” shall mean a material adverse effect on the business or properties, earnings, condition

(financial or otherwise) or prospects, taken as a whole, of the Company and its subsidiaries, considered as one enterprise, whether or not in the ordinary course of business.

(xiv) Authorization of the Purchase Agreements. The Purchase Agreements have been duly authorized, executed and delivered by or on behalf of the behalf of the Partnership.

(xv) No Conflicts. None of (i) the offering, issuance or sale by the Company of the Shares, (ii) the execution, delivery and performance of this Agreement by the Company, or (iii) the consummation of the transactions contemplated by this Agreement, (A) constitutes or will constitute a violation of the Organizational Agreements of the Targa Entities, (B) conflicts or will conflict with or constitutes or will constitute a breach or violation of, or a default (or an event that, with notice or lapse of time or both, would constitute such a default) under any agreement or other instrument filed as an exhibit to the Registration Statement or any document incorporated by reference therein, the TRC Credit Agreement or (C) violates or will violate the Delaware LP Act, the Delaware LLC Act, the Delaware General Corporation Law (the “DGCL”) or federal law, which conflicts, breaches, violations, defaults or Liens, in the case of clauses (B) or (C), would reasonably be expected to have a Material Adverse Effect or materially impair the ability of the Company to consummate the transactions provided for in this Agreement; provided, however, that no opinion need be expressed pursuant to this paragraph with respect to federal or state securities laws and other anti-fraud laws.

(xvi) No Consents. No permit, consent, approval, authorization, order, registration, filing or qualification under the Delaware LP Act, the Delaware LLC Act, the DGCL, Texas law or federal law is required in connection with the offering, issuance or sale by the Company of the Shares, the execution, delivery and performance of this Agreement by the Company, or the consummation of the transactions contemplated by this Agreement except (i) for such permits, consents, approvals and similar authorizations required under the Act, the Exchange Act, and state securities or “Blue Sky” laws, as to which such counsel need not express any opinion, (ii) for such consents which have been obtained or made, (iii) for such consents which, if not obtained, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or a material adverse effect on the ability of the Company to consummate the transactions contemplated by this Agreement or (iv) as disclosed in the Disclosure Package and the Final Prospectus.

(xvii) Effectiveness of Registration Statement. The Registration Statement became effective under the Act upon filing on May 23, 2016; any required filing of the Final Prospectus, and any supplements thereto, pursuant to Rule 424(b) has been made in the manner and within the time period required by Rule 424(b); to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or threatened.

(xviii) Form of Registration Statement and Final Prospectus. The Registration Statement, on the Effective Date, and the Final Prospectus, when filed with the Commission pursuant to Rule 424(b) and on the

Closing Date, were, on their face, appropriately responsive, in all material respects, to the requirements of the Act, except that in each case such counsel need express no opinion with respect to the financial statements or other financial and statistical data derived from the financial statements contained in or omitted from the Registration Statement or the Final Prospectus.

(xix) Descriptions and Summaries. The statements included in the Registration Statement and the Disclosure Package under the captions “Description of Capital Stock,” “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders,” “Business—Regulation of Operations,” “Business—Other Federal Laws and Regulations Affecting Our Industry” and “Business—Environmental and Operational Health and Safety Matters” insofar as they purport to constitute summaries of the terms of statutes, rules or regulations, legal or governmental proceedings or contracts and other documents, constitute accurate summaries of the terms of such statutes, rules and regulations, legal and governmental proceedings and contracts and other documents in all material respects.

(xx) Investment Company. The Company is not, and after giving effect to the offering and sale of the Shares and the application of the proceeds thereof as described in the Disclosure Package and the Final Prospectus, will not be, an “investment company” as defined in the Investment Company Act.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact, to the extent such counsel deems appropriate, upon the representations and warranties in this Agreement, upon certificates of officers and employees of the Targa Entities and upon information obtained from public officials, (ii) assume that all documents submitted to such counsel as originals are authentic, that all copies submitted to such counsel conform to the originals thereof, and that the signatures on all documents examined by such counsel are genuine, (iii) state that its opinion is limited to matters governed by federal law and the Delaware LP Act, Delaware LLC Act and the DGCL and the laws of the State of Texas and the laws of the State of New York, and (iv) state that they express no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local taxes or tax statutes to which any of the limited partners of the Partnership or any of the Targa Entities may be subject. Such counsel may exclude any non-wholly-owned entities from its opinion regarding ownership of Partnership Material Subsidiaries.

In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Company, the independent registered public accountants of the Company and the Underwriters, at which the contents of the Registration Statement, the Disclosure Package and the Final Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the Disclosure Package and the Final Prospectus (except to the extent specified in the foregoing opinion), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that:

(A) the Registration Statement, as of the Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(B) the Disclosure Package, as of the Execution Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or

(C) the Final Prospectus, as of its date and on the Closing Date contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that such counsel expresses no statement or belief with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s reports thereon, or any other financial and accounting information, included in, or incorporated by reference in, the Registration Statement or the Final Prospectus or the Disclosure Package, and (ii) representations and warranties and other statements of fact included in the exhibits to the Registration Statement or any document incorporated by reference therein.

(c) The Underwriters shall have received from ▇▇▇▇▇ ▇▇▇▇▇ L.L.P., counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Underwriters, with respect to the issuance and sale of the Shares, the Registration Statement, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Underwriters may reasonably require, and the Company shall have furnished to such counsel such documents as they may reasonably request for the purpose of enabling them to pass upon such matters.

(d) The Company shall have furnished to each Underwriter a certificate of the Company, signed on behalf of the Company by the Chief Executive Officer, Chief Financial Officer or President-Finance and Administration of the Company, dated the Closing Date, to the effect that the signers of such certificate have examined the Registration Statement, the Disclosure Package, the Final Prospectus and any amendment or supplement thereto, as well as each electronic road show used in connection with the offering of the Shares, and this Agreement and that:

(i) the representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened; and

(iii) since the date of the most recent financial statements included in the Disclosure Package and the Final Prospectus, there has been no Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus.

(e) The Underwriters shall have received, on each of the date hereof and the Closing Date, a letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Underwriters, from PricewaterhouseCoopers LLP, the independent registered public accountant, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in, or incorporated by reference in, the Registration Statement, the Disclosure Package and the Final Prospectus.

(f) The Company shall have paid the required Commission filing fees relating to the Shares within the time period required by Rule 456(b)(1)(i) of the Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Act and, if applicable, shall have updated the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b).

(g) Subsequent to the Execution Time, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Targa Entities taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Underwriters, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto).

(h) Prior to the Closing Date, the Company shall have furnished to the Underwriters such further information, certificates and documents as the Underwriters may reasonably request.

(i) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Targa Entities’ debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 3(a)(62) under the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(j) FINRA shall not have raised any objection with respect to the fairness and reasonableness of the terms and arrangements under this Agreement.

(k) The Firm Shares shall have been listed and admitted and authorized for trading on the NYSE, and satisfactory evidence of such actions shall have been provided to the Underwriters.

(l) At the Execution Time, the Company shall have furnished to the Underwriters a letter substantially in the form of Exhibit A hereto from each executive officer of the Company.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to any Underwriter and counsel for the Underwriters, this Agreement, as it relates to such Underwriter, and all obligations of such Underwriter hereunder may be canceled at, or at any time prior to, the Closing Date by such Underwriter. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of ▇▇▇▇▇ ▇▇▇▇▇ L.L.P., counsel for the Underwriters, at ▇▇▇▇ ▇▇▇▇ ▇▇▇., ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, on the Closing Date.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10(i) hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company will reimburse the Underwriters on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Shares.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless the Underwriters, the directors, officers, employees and agents of the Underwriters, affiliates of the Underwriters who have participated in the distribution of the Shares as Underwriters, and each person who controls any Underwriter or any such affiliate within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages, expenses or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages, expenses or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in any Preliminary Final Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or

supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating, preparing for or defending any such loss, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, expense or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Underwriters specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) The Underwriters agree to indemnify and hold harmless the Company, each of the Company’s directors and officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to the Underwriters furnished to the Company by or on behalf of such Underwriter specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that the following statements set forth in the Preliminary Final Prospectus and the Final Prospectus under the heading “Underwriting (Conflicts of Interest)” constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in the Preliminary Prospectus, the Final Prospectus and any Issuer Free Writing Prospectus: the fifth, eleventh and twelfth paragraphs.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. 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 reasonably 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. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and 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) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and each Underwriter severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and by any Underwriter, on the other, from the offering of the Shares, provided, however, that in no case shall the Underwriters be responsible for any amount in excess of the underwriting discount or commission applicable to the Shares purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute in such relative proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other, in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering of the Shares (after deducting underwriting discounts and commissions but before deducting expenses) received by the Company, as determined by this Agreement, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and each Underwriter agrees that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations

referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as any Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company, who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d) to collect such amounts from the Company, except in the event that the Company commences or becomes subject to any bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally.

9. Default by an Underwriter. If one Underwriter shall fail to purchase and pay for any of the Shares agreed to be purchased by such Underwriter hereunder and such failure to purchase shall constitute a default in the performance of its obligations under this Agreement, the remaining Underwriter shall be obligated severally to take up and pay for the Shares which the defaulting Underwriter agreed but failed to purchase; provided, however, that in the event that the aggregate number of Shares which the defaulting Underwriter agreed but failed to purchase shall exceed 10% of the aggregate number of Shares set forth in Schedule I hereto, the remaining Underwriter shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Shares, and if such nondefaulting Underwriter does not purchase all the Shares, this Agreement will terminate without liability to the nondefaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Underwriters shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Underwriter, by notice given to the Company prior to delivery of and payment for the Shares, if at any time prior to such delivery and payment (i) trading in the Company’s shares of Common Stock shall have been suspended by the Commission or the NYSE, (ii) trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (iii) a banking moratorium shall have been declared either by federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred, or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of such Underwriter, impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Preliminary Prospectus or the Final ▇▇▇▇▇▇▇▇▇▇.

▇▇

▇▇. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities, rights of contribution and other statements of the Company or the Company’s officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Shares. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

14. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliates through which they may be acting, on the other, (b) the Underwriters are acting solely as principals and not as agents or fiduciaries of the Company and (c) the Company’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

15. Research Analyst Independence. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may

arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions. The Company acknowledges that the Underwriters are full service securities firms and as such from time to time, subject to applicable securities laws, may effect transactions for their own account or the account of their customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

16. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters with respect to the subject matter hereof.

17. Applicable Law. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement, directly or indirectly, will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

18. Waiver of Jury Trial. The Company hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

19. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.
