(a) The Company will indemnify and hold harmless the Underwriter against any losses, claims, damages or liabilities, joint or several, to which the Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, or any Section 5(d) Writing, 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 will reimburse the Underwriter for any legal or other expenses reasonably incurred by the Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any Section 5(d) Writing, in reliance upon and in conformity with Underwriter Information or Selling Stockholder Information.

(b) The Selling Stockholder will indemnify and hold harmless the Underwriter against any losses, claims, damages or liabilities, joint or several, to which the Underwriter may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Section 5(d) Writing 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, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto or any Issuer Free Writing Prospectus or any Section 5(d) Writing in reliance upon and in conformity with written information furnished to the Company by the Selling Stockholder expressly for use therein; and will reimburse the Underwriter for any legal or other expenses reasonably incurred by the Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Selling Stockholder shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any amendment or supplement thereto or any Issuer Free Writing Prospectus or any Section 5(d) Writing in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein. Notwithstanding the foregoing provisions of this Section 9(b), the aggregate liability of the Selling Stockholder under this Section 9 shall not exceed the net proceeds from the offering (net of underwriting discounts and commissions but before deducting any other expenses) received by the Selling Stockholder from the sale of Shares under this Agreement.

(c) The Underwriter will indemnify and hold harmless the Company and the Selling Stockholder against any losses, claims, damages or liabilities to which the Company or the Selling Stockholder may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Basic Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, 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, in each case to the extent, but only to the

extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any such amendment or supplement thereto, any Issuer Free Writing Prospectus, in reliance upon and in conformity with Underwriter Information; and will reimburse the Company and the Selling Stockholder for any legal or other expenses reasonably incurred by the Company and the Selling Stockholder in connection with investigating or defending any such action or claim as such expenses are incurred.

(d) Promptly after receipt by an indemnified party under subsection (a), (b) or (c) of this Section 9 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so 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. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action 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.

(e) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such

proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriter on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (d) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholder on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (net of underwriting discounts and commissions but before deducting any other expenses) received by the Company and the Selling Stockholder bear to the total underwriting discounts and commissions received by the Underwriter, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Stockholder on the one hand or the Underwriter on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholder and the Underwriter agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriter has otherwise been required to pay by reason of 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. Notwithstanding the provisions of this subsection (e), the Selling Stockholder shall not be required to contribute pursuant to this Section 9 any amount in excess of the net proceeds from the offering (net of underwriting discounts and commissions but before deducting any other expenses) received by the Selling Stockholder from the sale of Shares under this Agreement.

(f) The obligations of the Company and the Selling Stockholder under this Section 9 shall be in addition to any liability which the Company and the Selling Stockholder may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Underwriter and each person, if any, who controls the Underwriter within the meaning of the Act and each broker-dealer affiliate of the Underwriter; and the obligations of the Underwriter under this Section 9 shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company) and to each person, if any, who controls the Company or the Selling Stockholder within the meaning of the Act.

11. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Selling Stockholder and the Underwriter, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of the Underwriter or any controlling person of the Underwriter, or the Company, or the Selling Stockholder, or any officer or director or controlling person of the Company, or any officer or director or controlling person of the Selling Stockholder, and shall survive delivery of and payment for the Shares.

12. If the Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder, then this Agreement shall thereupon terminate and neither the Company nor the Selling Stockholder shall then be under any liability to the Underwriter except as provided in Sections 7 and 9 hereof (but nothing herein shall relieve the Underwriter from liability for its default); but, if for any other reason, any Shares are not delivered by or on behalf of the Selling Stockholder as provided herein, the Selling Stockholder will reimburse the Underwriter for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriter in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Selling Stockholder shall then be under no further liability to the Underwriter except as provided in Sections 7 and 9 hereof.

13. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriter is required to obtain, verify and record information that identifies its clients, including the Company and the Selling Stockholder, which information may include the name and address of its clients, as well as other information that will allow the Underwriter to properly identify its clients.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriter shall be delivered or sent by mail, telex or facsimile transmission to you at Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282, Attention: Control Room; if to the Selling Stockholder shall be delivered or sent by mail, telex or facsimile transmission to the Selling Stockholder at 2800 Post Oak Boulevard, Suite 3800, Houston, Texas 77056, with a copy to Wachtell, Lipton, Rosen & Katz, 51 West 52^nd Street, New York, New York, 10019, Attention: David E. Shapiro and Mark F. Veblen; if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth on the cover of the Registration Statement, Attention: General Counsel, with a copy to Wachtell, Lipton, Rosen & Katz, 51 West 52^nd Street, New York, New York, 10019, Attention: David E. Shapiro and Mark F. Veblen; and if to any stockholder that has delivered a lock-up letter described in Section 8(k) hereof shall be delivered or sent by mail to his or her respective address provided in Schedule IV hereto or such other address as such stockholder provides in writing to the Company. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriter, the Company and the Selling Stockholder and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company, the Selling Stockholder or the Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from the Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

16. Each of the Company and the Selling Stockholder acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company and the Selling Stockholder, on the one hand, and the Underwriter, on the other, (ii) in connection therewith and with the process leading to such transaction the Underwriter is acting solely as a principal and not the agent or fiduciary of the Company and the Selling Stockholder, (iii) the Underwriter has not assumed an advisory or fiduciary responsibility in favor of the Company or the Selling Stockholder with respect to the offering and sale of Shares contemplated hereby or the process leading thereto (irrespective of whether the Underwriter has

advised or is currently advising the Company or the Selling Stockholder on other matters) or any other obligation to the Company or the Selling Stockholder except the obligations expressly set forth in this Agreement and (iv) each of the Company and the Selling Stockholder has consulted its own legal and financial advisors to the extent it deemed appropriate. Each of the Company and the Selling Stockholder agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company or the Selling Stockholder, in connection with such transaction or the process leading thereto.

17. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Selling Stockholder and the Underwriter, with respect to the subject matter hereof.

18. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

19. Each of the Company, the Selling Stockholder and the Underwriter 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.

20. This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same instrument.

21. Notwithstanding anything herein to the contrary, the Company and the Selling Stockholder are authorized to disclose to any persons the U.S. federal and state income “tax treatment” and “tax structure” (as such terms are defined in Treasury Regulations Section 1.6011-4(c)) of the transactions contemplated herein and all materials of any kind (including tax opinions and other tax analyses) provided to the Company and the Selling Stockholder relating to that treatment and structure, without the Underwriter imposing any limitation of any kind.

If the foregoing is in accordance with your understanding, please sign and return to us five counterparts hereof, and upon the acceptance hereof by you, this letter and such acceptance hereof shall constitute a binding agreement among the Underwriter, the Company and the Selling Stockholder.

Directors, Officers and Other Entities and Individuals to Deliver Lock-Up Agreements

The address for each Stockholder is: c/o Cadence Bancorporation, 2800 Post Oak Boulevard, Suite 3800, Houston, Texas 77056.

The undersigned understands that you (the “Underwriter”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Cadence Bancorporation, a Delaware corporation (the “Company”) and Cadence Bancorp, LLC, a Delaware limited liability company (the “Selling Stockholder”), providing for a public offering of the Class A Common Stock (the “Stock”) of the Company (the “Shares”) pursuant to a Registration Statement on Form S-3 filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriter to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period beginning from the date of this Lock-Up Agreement and continuing to and including the date 45 days after the date set forth on the final prospectus used to sell the Shares (the “Stockholder Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Stock of the Company, or any options or warrants to purchase any shares of Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Stock of the Company, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”) or make any public announcement of its intention to take any of the foregoing actions with respect to the Undersigned’s Shares. The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) by will or intestacy, provided that the legatee, heir or other transferee agrees to be bound in writing by the restrictions set forth herein, (iii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iv) pursuant to the Underwriting Agreement, (v) to the Company in full or partial payment of the exercise price for options to purchase the Company’s common stock that would otherwise expire during the Stockholder Lock-Up Period or to the Company in full or partial payment of taxes required to be paid upon the vesting of restricted shares of, or restricted stock units settleable in shares of, the Company’s common stock, in each case pursuant to the terms of the Company’s employee stock option or other employee or director incentive plans in effect on the date of the preliminary prospectus used to market the Shares and described in such preliminary prospectus and the final prospectus used to sell the Shares pursuant to the Underwriting Agreement, provided that if such transfers are required to be reported to the SEC on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended, during the Stockholder Lock-Up Period or the undersigned voluntarily effects any public filing or reporting regarding such transfers during the Stockholder Lock-Up Period, then the undersigned shall disclose in such filing the reasons for such transfers, or (vi) with the prior written consent of the Underwriter. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, the undersigned may transfer the undersigned’s Shares, (x) if the undersigned is a corporation, to any wholly-owned subsidiary of such corporation, (y) as part of a distribution to limited partners, members, unitholders or stockholders of the undersigned, or (z) to any corporation, partnership or other business entity with whom the undersigned shares in common an investment manager or advisor which has investment discretionary authority with respect to the undersigned’s and the entity’s investments pursuant to an investment advisory or similar agreement; provided, however, that in any such case, (A) it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such capital stock subject to the provisions of this Agreement and there shall be no further transfer of such capital stock except in accordance with this Agreement, (B) that any such transfer shall not involve a disposition for value, and (C) if such transfer is required to be reported to the SEC on Form 4 in accordance with Section 16 of the Securities Exchange Act of 1934, as amended, during the Stockholder Lock-Up Period or the undersigned voluntarily effects any public filing or reporting regarding such transfer during the Stockholder Lock-Up Period, then the undersigned shall disclose in such filing the reasons for such transfer. The undersigned now has, and, except as contemplated by clause (i), (ii), (iii), (iv), or (v) above or the immediately preceding sentence and except with regards to liens, encumbrances and claims existing as of the date hereof or to be in effect prior to the Lock-up Commencement Date all as set forth on Schedule A attached hereto above, for the duration of this Lock-Up Agreement will have, good and marketable title to the Undersigned’s Shares, free and clear of all liens, encumbrances, and claims whatsoever. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions.

Notwithstanding anything herein to the contrary, the foregoing shall not be deemed to restrict the undersigned from exercising options or warrants to purchase shares of the Company’s common stock during the Lock-Up Period, provided in all such cases that no sale, disposition or other transfer of the underlying shares of the Company’s common stock occurs during the Lock-Up Period (other than as provided herein).

This Lock-Up Agreement shall automatically terminate upon the earliest to occur, if any, of (1) the Underwriter advising the Company in writing, prior to the execution of the Underwriting Agreement, that they have determined not to proceed with the Public Offering, (2) termination of the Underwriting Agreement before the sale of any Shares to the Underwriter, (3) withdrawal of the registration statement filed with the SEC with respect to the Public Offering, or (4) August 24, 2018, in the event that the Underwriting Agreement has not been executed by that date.

The undersigned understands that the Company and the Underwriter are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

Very truly yours,
