3. Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, the Company and each Selling Stockholder agree, severally and not jointly, to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company and each Selling Stockholder, at a purchase price of $[·] per share, that number of Firm Securities (subject to adjustment by the Representatives in their discretion to eliminate fractions) obtained by multiplying 3,000,000 Firm Securities in the case of the Company and the number of Firm Securities set forth opposite the name of such Selling Stockholder in Schedule A hereto, in the case of a Selling Stockholder, in each case by a fraction the numerator of which is the number of Firm Securities set forth opposite the name of such Underwriter in Schedule B hereto and the denominator of which is the total number of Firm Securities.

The Company and the Selling Stockholders will deliver the Firm Securities to or as instructed by the Representatives for the accounts of the several Underwriters in a form reasonably acceptable to the Representatives against payment of the purchase price in Federal (same day) funds by official bank check or checks or wire transfer to an account at a bank acceptable to the Representatives drawn to the order of the Company, at the office of Latham & Watkins LLP, 811 Main Street, Suite 3700, Houston, Texas 77002, at 9:00 am (Eastern Time), on [·], 2017, or at such other time not later than seven full business days thereafter as the Representatives and the Company determine, such time being herein referred to as the “First Closing Date”. For purposes of Rule 15c6-1 under the Securities Exchange Act of 1934, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. Delivery of the Firm Securities will be made through the facilities of the DTC unless the Representatives shall otherwise instruct.

In addition, upon written notice from the Representatives given to the Company and the Selling Stockholders from time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per Security to be paid for the Firm Securities. Such notice shall set forth (i) the aggregate number of shares of Optional Securities to be sold by the Company as to which the Underwriters are exercising the option and (ii) the time, date and place at which the Optional Securities will be delivered (each time for the delivery of and payment for the Optional Securities being herein referred to as an “Optional Closing Date,” which may be the First Closing Date) (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”). Each Selling Stockholder agrees to sell to the Underwriters the number of shares set forth opposite the names of such Selling Stockholder in Schedule A hereto under the caption “Number of Optional Securities to be Sold”. Such Optional Securities shall be purchased from the Selling Stockholders, severally and not jointly, for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter’s name bears to the total number of Firm Securities (subject to adjustment by the Representatives to eliminate fractions). No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Representatives to the Company and the Selling Stockholders.

Each Optional Closing Date shall be determined by the Representatives but shall be not later than five full business days after written notice of election to purchase Optional Securities is given.

bank check or checks or wire transfer to an account at a bank acceptable to the Representatives drawn to the order of the Company, at the above office of Latham & Watkins LLP. The delivery of any Optional Securities will be made through the facilities of the DTC unless the Representatives shall otherwise instruct.

(a) Additional Filings. The Company will file the Final Prospectus, in a form approved by the Representatives, with the Commission pursuant to and in accordance with subparagraph (1) (or, if applicable and if consented to by the Representatives, subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the second business day following the execution and delivery of this Agreement or (B) the fifteenth business day after the Effective Time of the Initial Registration Statement. The Company will advise the Representatives promptly of any such filing pursuant to Rule 424(b) and provide satisfactory evidence to the Representatives of such timely filing. If an Additional Registration Statement is necessary to register a portion of the Offered Securities under the Act but the Effective Time thereof has not occurred as of the execution and delivery of this Agreement, the Company will file the additional registration statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date of this Agreement or, if earlier, on or prior to the time the Final Prospectus is finalized and distributed to any Underwriter, or will make such filing at such later date as shall have been consented to by the Representatives.

The Company will promptly advise the Representatives of any proposal to amend or supplement at any time the Initial Registration Statement, any Additional Registration Statement or any Statutory Prospectus and will not effect such amendment or supplementation without the Representatives’ consent; and the Company will also advise the Representatives promptly of (i) the effectiveness of any Additional Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement), (ii) any amendment or supplementation of a Registration Statement or any Statutory Prospectus, (iii) any request by the Commission or its staff for any amendment to any Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iv) the institution by the Commission of any stop order proceedings in respect of a Registration Statement or the threatening of any proceeding for that purpose, and (v) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Representatives of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of the Representatives, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Representatives’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d) Testing-the-Waters Communication. If at any time following the distribution of any Written Testing-the-Waters Communication there occurred or occurs an event or development as a result of which such Written Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Written Testing-the-Waters Communication to eliminate or correct such statement or omission.

(e) Rule 158. As soon as practicable, but not later than the Availability Date (as defined below), the Company will make generally available to its security holders an earnings statement covering a period of at least 12 months beginning after the Effective Time of the Initial Registration Statement (or, if later, the Effective Time of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act. For the purpose of the preceding sentence, “Availability Date” means the day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time on which the Company is required to file its Form 10-Q for such fiscal quarter except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the day after the end of such fourth fiscal quarter on which the Company is required to file its Form 10-K.

(f) Furnishing of Prospectuses. The Company will furnish to the Representatives copies of each Registration Statement (three of which will be signed and will include all exhibits), each related Statutory Prospectus, and, so long as a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Representatives request. The Final Prospectus shall be so furnished within two business days following the execution and delivery of this agreement, unless otherwise agreed by the Company and the Representatives. All other such documents shall be so furnished as soon as available, unless otherwise agreed by the Company and the Representatives. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

(g) Blue Sky Qualifications. The Company shall cooperate with the Underwriters and counsel for the Underwriters to qualify or register the Offered Securities for resale under (or obtain exemptions from the application of) the state securities or Blue Sky laws of those jurisdictions designated by the Underwriters, shall comply with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Offered Securities. Notwithstanding the foregoing, the Company shall not be required to qualify as a foreign corporation or to take any action that would subject it to general service of process or taxation in any such jurisdiction where it is not presently qualified or subject to taxation.

(h) Reporting Requirements. During the period of five years hereafter, the Company will furnish to the Representatives and, upon request, to each of the other Underwriters, as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Representatives (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Representatives may reasonably request. However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“EDGAR”), it is not required to furnish such reports or statements to the Underwriters.

(i) Payment of Expenses. The Company agrees with the several Underwriters that the Company will pay all expenses incident to the performance of the obligations of the Company under this Agreement, including but not limited to (i) any filing fees and reasonable attorneys’ fees and expenses incurred by the Company or the Underwriters in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Offered Securities

for offer and sale under the state securities or Blue Sky laws of such jurisdictions as the Representatives designate and the preparation and printing of memoranda relating thereto, (ii) the filing fees incident to, and the reasonable fees and expenses of counsel for the Underwriters up to $30,000, in connection with FINRA’s review and approval of the Underwriters’ participation in the offering and distribution of the Offered Securities, (iii) fees and expenses incident to listing the Offered Securities on the New York Stock Exchange, (iv) fees and expenses in connection with the registration of the Offered Securities under the Exchange Act, (v) expenses incurred in distributing preliminary prospectuses, the Final Prospectus (including any amendments and supplements thereto) and the Registration Statement and exhibits thereto to the Underwriters and expenses incurred for preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors and (vi) all other fees, costs and expenses referred to in Item 13 of Part II of the Registration Statement. The Company will also pay or reimburse the Underwriters (to the extent incurred by them) for costs and expenses of the Company’s officers and employees and any other expenses of the Company relating to investor presentations or any “road show” in connection with the offering and sale of the Offered Securities including, without limitation, any travel expenses of the Company’s officers and employees and any other expenses of the Company, including 50% of the cost of the chartering of airplanes. It is understood, however, that except as provided in this Section 5(i) and Sections 8 and 10 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel and any road show expenses incurred by them (other than costs and expenses incurred by the Underwriters on behalf of the Company).

(j) Use of Proceeds. The Company will use the net proceeds received by it in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package and the Final Prospectus and, except as disclosed in the General Disclosure Package and the Final Prospectus, the Company does not intend to use any of the proceeds from the sale of the Offered Securities hereunder to repay any outstanding debt owed to any affiliate of any Underwriter.

(k) Absence of Manipulation. The Company and the Selling Stockholders severally and not jointly agree that they will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Offered Securities.

(l) Restriction on Sale of Securities by the Company.

provided that (A) no more than an aggregate of 10% of the number of shares of the Company’s capital stock outstanding as of the First Closing Date are issued as consideration in connection with all such acquisitions and (B) prior to the issuance of such shares of the Company’s capital stock each recipient of such shares agrees in writing to be subject to the “lock-up” described in this Section 5(l) for the remaining term of the Lock-Up Period. The initial Lock-Up Period will commence on the date hereof and continue for 90 days after the date hereof or such earlier date that the Representatives consent to in writing.

6. Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company and the Representatives, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company and the Representatives agree that any such Permitted Free Writing Prospectus is listed on Schedule C hereto. The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The Company represents that it has satisfied and agrees that it will satisfy the conditions in Rule 433 to avoid a requirement to file with the Commission any electronic road show.

7. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Firm Securities on the First Closing Date and the Optional Securities to be purchased on each Optional Closing Date will be subject to the accuracy of the representations and warranties of the Company and the Selling Stockholders herein (as though made on such Closing Date), to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company and the Selling Stockholders of their obligations hereunder and to the following additional conditions precedent:

The Final Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 5(a) hereof.

The Representatives may in their sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder, whether in respect of an Optional Closing Date or otherwise.

8. Indemnification and Contribution.

(a) Indemnification of Underwriters by the Company. The Company will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus, 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 of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company will 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 in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below.

(b) Indemnification of Underwriters by Selling Stockholders. The Selling Stockholders, severally and not jointly, will indemnify and hold harmless each Underwriter, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus, any Written Testing-the-Waters Communication or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding

whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to the above as such expenses are incurred; provided, however, that a Selling Stockholder will only 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 in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any such Selling Stockholder specifically for use therein, it being understood and agreed that the only such information furnished by any Selling Stockholder consists of the following information: each Selling Stockholder’s name and corresponding share amounts set forth in the table of Principal and Selling Stockholders in the Registration Statement and Final Prospectus under the heading “Principal and Selling Stockholders” and each Selling Stockholder’s address.

(c) Indemnification of Company and Selling Stockholders. Each Underwriter will severally and not jointly indemnify and hold harmless the Company, each of its directors and each of its officers who signs a Registration Statement, each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each Selling Stockholder and each person, if any, who controls any of the Selling Stockholders within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Underwriter Indemnified Party”) against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Act, the Exchange Act, or other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any Registration Statement at any time, any Statutory Prospectus at any time, the Final Prospectus, any Issuer Free Writing Prospectus or any Written Testing-the-Waters Communication, or arise out of or are based upon the omission or the alleged omission of 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 reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: (i) the concession and reallowance figures appearing in the fourth paragraph under the caption “Underwriting” and (ii) the paragraph relating to stabilization by the Underwriters under the caption “Underwriting”.

(d) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may 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 will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the

prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action 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 an indemnified party.

(e) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) 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 from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Selling Stockholders on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities 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. 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, the Selling Stockholders or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of 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 action or claim which is the subject of this subsection (e). 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 Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of 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. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) 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 in this Section 8(d).

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder on either the First Closing Date or any Optional Closing Date and the aggregate number of shares of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date, the Representatives may make arrangements satisfactory to the Company and the Selling Stockholders for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by such Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase on such Closing Date. If any Underwriter or Underwriters so default and the aggregate number of shares of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Offered Securities that the Underwriters are obligated to purchase on such Closing Date and arrangements satisfactory to the Representatives and the Company for

the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders, except as provided in Section 10 (provided that if such default occurs with respect to Optional Securities after the First Closing Date, this Agreement will not terminate as to the Firm Securities or any Optional Securities purchased prior to such termination). As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Selling Stockholders, of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, any Selling Stockholders, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iv), (vi), (vii) or (viii) of Section 7(c) hereof, the Company will, reimburse the Underwriters for all out-of-pocket expenses (including reasonable documented fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company, the Selling Stockholders and the Underwriters pursuant to Section 8 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

11. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, hand delivered or telecopied and confirmed to the Representatives at Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, New York 10010-3629, Attention: IBCM-Legal and Goldman Sachs & Co. LLC, 200 West Street, New York, New York 10282, if sent to the Company, will be mailed, hand delivered or telecopied and confirmed to it at 9811 Katy Freeway, Suite 900, Houston, Texas 77024 Attention: Chief Financial Officer, or if sent to any of the Selling Stockholders, will be mailed, hand delivered or telecopied and confirmed to such Selling Stockholder at the address for such Selling Stockholder set forth in Schedule A.; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, hand delivered or telecopied and confirmed to such Underwriter.

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

13. Representation of Underwriters. The Representatives will act for the several Underwriters in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representatives jointly or by Credit Suisse Securities (USA) LLC will be binding upon all the Underwriters.

14. Counterparts. This Agreement may be executed 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 Agreement.

15. Absence of Fiduciary Relationship. The Company and the Selling Stockholders acknowledge and agree that:

(a) No Other Relationship. The Representatives have been retained solely to act as underwriters in connection with the sale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Company and the Selling Stockholders, on the one hand, and the Representatives, on the other, has been created in respect of any of the transactions contemplated by

this Agreement or the Final Prospectus, irrespective of whether the Representatives have advised or are advising the Company or the Selling Stockholders on other matters;

(b) Arms’-Length Negotiations. The price of the Offered Securities set forth in this Agreement was established by the Company and the Selling Stockholders following discussions and arms-length negotiations with the Representatives and the Company and the Selling Stockholders are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Absence of Obligation to Disclose. The Company and the Selling Stockholders have been advised that the Representatives and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company or the Selling Stockholders and that the Representatives have no obligation to disclose such interests and transactions to the Company or the Selling Stockholders by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. The Company and the Selling Stockholders waive, to the fullest extent permitted by law, any claims they may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty and agree that the Representatives shall have no liability (whether direct or indirect) to the Company or the Selling Stockholders in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

16. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in the City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.

17. Patriot Act. 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.

the Registration Statement to have any securities registered pursuant to the Registration Statement or registered by the Company under the Securities Act or otherwise.

8.              The execution and delivery of the Underwriting Agreement by the Company does not, and the performance by the Company of its obligations under the Underwriting Agreement, the offering, issuance and sale of the Offered Securities pursuant to the terms of the Underwriting Agreement and the application of the proceeds from the sale of the Offered Securities as described under “Use of Proceeds” in the Prospectus will not, (a) result in a breach or default (or an event that, with notice or lapse of time or both, would constitute such an event) under any agreement that is filed as an exhibit to the Registration Statement; (b) violate the provisions of the Governing Documents or the similar organizational documents of the Company’s subsidiaries; (c) violate any federal, New York or Texas statute, rule or regulation applicable to the Company or the DGCL or the Delaware LLC Act, or (d) result in the creation of any additional lien upon any property or assets of the Company or its subsidiaries under the Credit Agreement except, with respect to clauses (c) and (d), as would not, individually or in the aggregate, reasonably be expected to materially impair the ability of the Company and its subsidiaries to consummate the transactions contemplated by the Underwriting Agreement in connection with the offering, issuance and sale of the Offered Securities by the Company (a “Material Adverse Effect”); it being understood that we express no opinion in clause (c) of this paragraph (5) with respect to any federal or state securities, Blue Sky or anti-fraud laws, rules or regulations.

9.              The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

10.       No consent, approval, authorization or order of, registration or qualification with any federal, Texas or New York court or governmental agency or any Delaware court or governmental agency acting pursuant to the DGCL is required to be obtained or made by the Company or its subsidiaries for the execution, delivery and performance by the Company of the Underwriting Agreement, the compliance by the Company with the terms thereof and the issuance and sale of the Offered Securities by the Company being delivered on the date hereof pursuant to the Underwriting Agreement, except (i) as have been obtained or made, (ii) for the registration of the offering and sale of the Offered Securities under the Securities Act, (iii) for such consents, approvals, authorizations, orders, registrations or qualifications as may be required under applicable federal or state securities or Blue Sky laws and the approval by FINRA of the underwriting terms and arrangements in connection with the purchase and distribution of the Offered Securities by the Underwriters or (iv) for such consents that, if not obtained, have not or would not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

11.       The Registration Statement has been declared effective under the Act; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Final Prospectus pursuant to Rule 424(b) under the Act has been made in the manner and within the time period required by such rule.

12.       The statements set forth in the Final Prospectus under the headings “Business—Environmental and Occupational Health and Safety Regulations,” “Description of Capital Stock,” “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders,” and “Shares Eligible for Future Sale” and in the Registration Statement in Item 14, to the extent that they constitute descriptions or summaries of the terms of the Common Stock or the documents referred to therein, or refer to statements of federal law, the laws of the State of Delaware or legal conclusions, are accurate in all material respects.

13.       The Company is not, and after giving effect to the offer and sale of the Offered Securities pursuant to the terms of the Underwriting Agreement and application of the net proceeds therefrom as described in the General Disclosure Package and the Final Prospectus under the caption “Use of Proceeds,” will not be, an “investment company” as defined in the Investment Company Act.

14.       Each of the Registration Statement, at the time it was declared effective, the General Disclosure Package, as of the Applicable Time, and the Final Prospectus, when filed with the Commission pursuant to Rule 424(b) under the Securities Act and at the Closing Date (in each case other than (a) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon and (b) the other financial data derived therefrom, in each case included in or omitted from the Registration Statement, the General

Disclosure Package and the Prospectus, as to which we express no opinion), appears on their face to comply as to form in all material respects with the requirements of the Securities Act.

15.       The Solaris LLC Agreement constitutes a valid and legally binding agreement of each of the Company Parties, enforceable against each of the Company Parties in accordance with its terms, provided that the enforceability thereof may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

We have participated in conferences with representatives of the Company and with representatives of its independent accountants and counsel for the Underwriters, at which conferences the contents of the Registration Statement, the General Disclosure Package and the Final Prospectus and any amendment and supplement thereto and related matters were discussed. Although we have not undertaken to determine independently, and do not assume any responsibility for, or express opinion regarding (other than listed in paragraph 13 above), the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package or the Prospectus, based upon the participation described above (relying as to factual matters upon statements of fact made to us by representatives of the Company), nothing has come to our attention to cause us to believe that:

(a)                                 the Registration Statement, at the time it was declared effective (including the information, if any, deemed pursuant to Rule 430A to be part of the Registration Statement at the time of effectiveness), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading;

(b)                                 the General Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a 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 as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits 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;

except that in each case such counsel need not express any belief with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon or (ii) any other financial or accounting information, in each case included in or omitted from the Registration Statement, the General Disclosure Package and the Prospectus.

Dear Sirs:

As an inducement to the Underwriters to execute the Underwriting Agreement (the “Underwriting Agreement”), pursuant to which an offering will be made that is intended to result in the establishment of a public market for the Class A common stock, par value $0.01 per share (the “Securities”), of Solaris Oilfield Infrastructure, 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 and Goldman Sachs & Co. LLC (the “Representatives”). In addition, the undersigned agrees that, without the prior written consent of the Representatives, 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 Lock-Up Period will commence on the date of this Lock-Up Agreement and continue and include the date 90 days after the public offering date set forth on the final prospectus used to sell the Securities (the “Public Offering Date”) pursuant to the Underwriting Agreement.

Any Securities received upon exercise of options or other securities of the Company granted to the undersigned and any Securities acquired by the undersigned in the open market will also be subject to this Lock-Up Agreement. Additionally, the restrictions in this Lock-Up Agreement shall not apply to (a) any transactions relating to Securities acquired in the open market after the closing of the offering, 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, (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, provided that in each transfer pursuant to clauses (c) through (e) 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), or (f) the establishment of any written contract, instruction or plan that satisfies all of the requirements of Rule 10b5-1 (a “Rule 10b5-1 Plan”) under the Exchange Act; provided, however, that no sales of Securities or securities convertible into, or exchangeable or exercisable for, Securities, shall be made pursuant to a Rule 10b5-1 Plan prior to the expiration of the Lock-Up Period (as the same may be extended pursuant to the provisions hereof); and provided further, that no party is required to publicly announce, file, or report the establishment of such Rule 10b5-1 Plan in any public report, announcement, or filing with the Commission under the Exchange Act during the Lock-Up Period and does not otherwise voluntarily effect any such public report, announcement, or filing regarding such Rule 10b5-1 Plan.

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) the Representatives 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, the Representatives 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.

It is understood that if the Underwriting Agreement is executed yet terminates (other than the provisions thereof that survive termination) prior to payment for and delivery of the Offered Securities, the undersigned shall be released from all obligations under this Lock-Up Agreement.
