(e) The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus or Written Testing-the-Waters Communication any event occurred or occurs as a result of which such Issuer Free Writing Prospectus or Written Testing-the-Waters Communication, as applicable, would conflict with the information in the Registration Statement, the Pricing Prospectus or the Prospectus or would include an 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 then prevailing, not misleading, the Company will give prompt notice thereof to Credit Suisse Securities (USA) LLC and, if requested by Credit Suisse Securities (USA) LLC, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus, Written Testing-the-Waters Communication or other document which will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus or Written Testing-the-Waters Communication made in reliance upon and in conformity with information furnished in writing to the Company by an Underwriter through the Representatives expressly for use therein.

11. (a)(1) The Company will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such 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, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act or any Written Testing-the-Waters Communication, 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 each Underwriter for any legal or other expenses reasonably incurred by such 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, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives expressly for use therein.

(2) The Company will indemnify and hold harmless each Selling Stockholder against any losses, claims, damages or liabilities, joint or several, to which such 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 Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act or any Written Testing-the-Waters Communication, 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 each Selling Stockholder for any legal or other expenses reasonably incurred by such 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, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, in reliance upon and in conformity with written information furnished to the Company by a Selling Stockholder expressly for use therein that constitutes the Selling Stockholder Information (it being understood, for the avoidance of doubt, that this Section 11(a)(2) shall in no event affect any liability the Company may have to any Underwriter, or any partner, member, director, officer, employee, agent, affiliate of any Underwriter, or any person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and (ii) is an agreement solely between the Company and any Selling Stockholder and the other parties described in this Section 11(a)(2) and the Underwriters shall have no responsibility in connection with any dispute between the Company, any Selling Stockholder and any other party described in this Section 11(a)(2) with respect to an agreement solely between the Company and any Selling Stockholder and the other parties described in this Section 11(a)(2)).

(b) The Selling Stockholders, severally and not jointly, will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such 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, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act, any “free writing prospectus” (as defined in Rule 405 under the Securities Act) (any such “free writing prospectus” that was prepared by or on behalf of the Selling Stockholder or used or referred to by the Selling Stockholder in connection with the offering of the Stock in violation of Section 8(a) being referred to as a “Selling Stockholder Free Writing Prospectus”), or any Written Testing-the-Waters Communication, 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 only with respect to such Selling Stockholder’s Selling Stockholder Information and to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with such Selling Stockholder’s Selling Stockholder Information; and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred. The aggregate liability of each Selling Stockholder under this subsection (b) shall be limited to an amount equal to the aggregate net proceeds, after underwriting discounts but before deducting expenses, received by such Selling Stockholder, from the offering of such Selling Stockholder’s Shares purchased under this Agreement received by the Selling Stockholder.

(c) Each Underwriter will indemnify and hold harmless the Company and the Selling Stockholders against any losses, claims, damages or liabilities to which the Company or any 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 Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication 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, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use therein; and will reimburse the Company and the Selling Stockholders for any legal or other expenses reasonably incurred by the Company and the Selling Stockholders 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) above 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 reasonably 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 11 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 Stockholders on the one hand and the Underwriters on the other, or by the Company on the one hand and the Selling Stockholders, on the other, as applicable, 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 Stockholders on the one hand and the Underwriters on the other, or of the Company on the one hand and the Selling Stockholders, on the other, as applicable, 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 Stockholders on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative benefits received by the Company, on the one hand, and the Selling Stockholders, on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total net proceeds from the offering (before deducting expenses) received by the Selling Stockholders, 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

or the Selling Stockholders on the one hand or the Underwriters on the other, or by the Company on the one hand and the Selling Stockholders, on the other, as applicable, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation (even if the 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 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), no Underwriter shall 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 such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the foregoing provisions of this subsection (e), no Selling Stockholder shall be required to (i) contribute unless such Selling Stockholder would have had indemnification obligations pursuant to subsection (b) above or (ii) contribute any amount in excess of the amount by which such Selling Stockholder’s aggregate net proceeds, after underwriting discounts but before deducting expenses received by such Selling Stockholder, from the offering of such Selling Stockholder’s Shares purchased under this Agreement, exceeds the amount of any damages which such Selling Stockholder has otherwise been required to pay by reason of such untrue statement or omission or alleged omission pursuant to subsection (b) above. 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. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. In addition, the Selling Stockholders’ obligations in this subsection (e) to contribute are several in proportion to their respective sale of Shares not joint.

(f) The obligations of the Company and the Selling Stockholders under this Section 11 shall be in addition to any liability which the Company or Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act and each broker-dealer affiliate of any Underwriter; and the obligations of the Underwriters under this Section 11 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of each of the

Company and the Selling Stockholders (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company or a Selling Stockholder) and to each person, if any, who controls the Company or Selling Stockholder within the meaning of the Act.

12. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company and the Selling Stockholders shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company and the Selling Stockholders that you have so arranged for the purchase of such Shares, or the Company or the Selling Stockholders notify you that they have so arranged for the purchase of such Shares, you, the Company or the Selling Stockholders shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in your reasonable opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Company and the Selling Stockholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you, the Company and the Selling Stockholders as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if

the Company and the Selling Stockholders shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Subsequent Time of Delivery, the obligations of the Underwriters to purchase and of the Selling Stockholders to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders, except for the expenses to be borne by the Company and the Underwriters as provided in Section 9 hereof and the indemnity and contribution agreements in Section 11 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

13. The respective indemnities, agreements, representations, warranties and other statements of the Company, the several Selling Stockholders and the several Underwriters, 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 any Underwriter or any controlling person of any Underwriter, any of the Company, or any officer or director or controlling person of any of the Company or any of the Selling Stockholders or any officer or director or controlling person of any of the Selling Stockholders, and shall survive delivery of and payment for the Shares.

14. If this Agreement shall be terminated pursuant to Section 12 hereof, the Company and the Selling Stockholders shall not then be under any liability to any Underwriter except as provided in Section 9 hereof, with respect to the Company, and Section 11 hereof, with respect to the Company and the Selling Stockholders; but, if for any other reason, any Shares are not delivered by or on behalf of the Company or any of the Selling Stockholders as provided herein, the Company will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company and the Selling Stockholders shall then be under no further liability to any Underwriter except as provided in Section 9 hereof, with respect to the Company, and Section 11 hereof, with respect to the Company and the Selling Stockholders.

15. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly or by Credit Suisse Securities (USA) LLC or Goldman, Sachs & Co. on behalf of you as the representatives.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to you as the representatives to each of: (i) Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629,

Attention: LCD-IBD; and (ii) Goldman, Sachs & Co., 200 West Street, New York, New York 10282-2198, Attention: Registration Department; if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; and if to the Selling Stockholders shall be delivered or sent by mail, telex or facsimile transmission to the address set forth on Schedule VI hereto; provided, however, that any notice to an Underwriter pursuant to Section 11(d) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

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

16. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company, the Selling Stockholders and, to the extent provided in Sections 11 and 13 hereof, the officers, members and directors of any of the Company or Selling Stockholders and each person who controls any of the Company, any of the Selling Stockholders or any 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 any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

17. 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.

Dear Sirs:

As an inducement to the Underwriters to execute the Underwriting Agreement (the “Underwriting Agreement”), pursuant to which an offering will be made for 5,950,000 shares of the common stock, par value $0.001 per share (the “Securities”), of Smart Sand, Inc., and any successor (by merger or otherwise) thereto (the “Company”), the undersigned hereby agrees that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Securities or securities convertible into or exchangeable or exercisable for any Securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the Securities, whether any such aforementioned transaction is to be settled by delivery of the Securities or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Credit Suisse Securities (USA) LLC (“Credit Suisse”) and Goldman, Sachs & Co (“Goldman Sachs”). In addition, the undersigned agrees that, without the prior written consent of Credit Suisse and Goldman Sachs, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Securities or any security convertible into or exercisable or exchangeable for the Securities.

The initial Lock-Up Period will commence on the date of this letter agreement (this “Lock-Up Agreement”) and end on the expiration of that certain Lock-Up Agreement dated as of November 3, 2016 to which you are a party.

Any Securities received upon exercise of options or other securities of the Company granted to the undersigned will also be subject to this Lock-Up Agreement. Any Securities acquired by the undersigned in the open market will not be subject to this Lock-Up Agreement; provided that with respect to any sale or other disposition of such Securities, no filing under the Securities Exchange Act of 1934 (the “Exchange Act”) (other than on Form 5) or other public announcement shall be required or shall be voluntarily made by any party in connection with subsequent sales of such Securities acquired in such open market transactions during the Lock-Up Period. In addition, the restrictions in this Lock-Up Agreement shall not apply to (a) any transfer pursuant to the terms of the Underwriting Agreement, (b) any exercise of options or vesting or exercise of any other equity-based award, in each case, outstanding on the Public Offering Date, and in each case under the Company’s equity incentive plan or any other plan or agreement described in the prospectus included in the Registration Statement, provided that any Securities received upon such exercise or vesting will also be subject to this Lock-Up Agreement, (c) transfers as a bona fide gift or gifts, (d) transfers to a family member, trust, family limited partnership or family limited liability company for the direct or indirect benefit of the undersigned or his or her family members, (e) transfers by testate or intestate succession, (f) transfers to the undersigned’s direct or indirect affiliates (as defined in Rule 12b-2 of the Exchange Act), including without limitation its direct and indirect stockholders, members and partners and its direct and indirect subsidiaries, or to any investment fund or other entity controlled or managed by, or under the common control or management with, the undersigned, provided that in each transfer pursuant to clauses (c)-(f) the transferee agrees to be bound in writing by the terms of this Lock-Up Agreement prior to such transfer, such transfer shall not involve a disposition for value and no filing or public announcement by any party (donor, donee, transferor or transferee) under the Exchange Act or otherwise shall be required or shall be voluntarily made in connection with such transfer (other than a filing on a Form 5), (g) transfers pursuant to an order of a court or regulatory agency, or (h) transfers with the prior written consent of Credit Suisse and Goldman Sachs.

Notwithstanding anything herein to the contrary, the undersigned may (a) enter into a written trading plan established pursuant to Rule 10b5-1 of the Exchange Act during the Lock-Up Period, and the Company may announce the establishment of such a plan, provided that no direct or indirect offers, pledges, sales, contracts to sell, sales of any option or contract to purchase, purchases of any option or contract to sell, grants of any option, right or warrant to purchase, loans, or other transfers or disposals of any Securities or any securities convertible into or exercisable or exchangeable for Securities may be effected pursuant to such plan during the Lock-Up Period and (b) transfer Securities (or any security convertible into or exercisable or exchangeable for Securities) pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction involving a Change of Control (as defined below) that is approved by the Board of Directors of the Company; provided that in the event that such tender offer, merger, consolidation or other such transaction is not completed, the Securities held by the undersigned shall remain subject to the provisions of this Lock-Up Agreement. For purposes of this Lock-Up Agreement, “Change of Control” shall mean the transfer (whether by tender offer, merger, consolidation or other similar transaction), in one transaction or a series of related transactions, to a person or group of affiliated persons (other

than an underwriter pursuant to the offering), of the Company’s voting securities if, after such transfer, such person or group of affiliated persons would hold more than 50% of the outstanding voting securities of the Company (or the surviving entity).

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of Securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

If the undersigned is an officer or director of the Company, (i) Credit Suisse and Goldman Sachs agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Securities, Credit Suisse and Goldman Sachs will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by Credit Suisse and Goldman Sachs hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this Lock-Up Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Lock-Up Agreement shall lapse and become null and void (a) at the time at which Credit Suisse and Goldman Sachs, on behalf of the Underwriters, on the one hand, or the Company, on the other hand, advise the other in writing prior to the execution of the Underwriting Agreement that they have or it has determined not to proceed with the offering, (b) the termination of the Underwriting Agreement before the sale of any Securities to the Underwriters, (c) the withdrawal of the registration statement filed with the Securities and Exchange Commission with respect to the offering and (d) if the Public Offering Date shall not have occurred on or before February 28, 2017. This agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Very truly yours,

[Name of stockholder]
