Any certificate signed by any officer of the Company or any Subsidiary delivered to any Underwriter or to counsel for any Underwriter pursuant to or in connection with this Agreement shall be deemed a representation and warranty by the Company or such Subsidiary to any Underwriter as to the matters covered thereby.

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 agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Company, at a purchase price of $13.125 per share, that number of Firm Securities (rounded up or down, as determined by the Representatives in their discretion, in order to avoid fractions) set forth opposite the name of such Underwriter in Schedule A hereto.

(a) The Company will deliver the Firm Securities to or as instructed by the Representatives through the facilities of the DTC 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 wire transfer to accounts at banks designated by the Company, at the office of ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P., ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, at 10:00 a.m., New York time, on April 26, 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 Exchange Act, 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.

(b) In addition, upon written notice from the Representatives given to the Company from time to time but 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 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 Option 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”). The Company agrees to sell to the Underwriters the number of Optional Shares specified in such notice and the Underwriters agree, severally and not jointly, to purchase such Optional Securities. Such Optional Securities shall be purchased for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter’s name on Schedule A bears to the total number of Firm Securities (subject to adjustment by the Representatives to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. 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.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Final Prospectus.

5. Certain Agreements of the Company. The Company agrees with the several Underwriters, as applicable, that:

(a) Additional Filings. Unless filed pursuant to Rule 462(c) as part of the Additional Registration Statement in accordance with the next sentence, 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 (i) the second business day following the execution and delivery of this Agreement or (ii) 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.

(b) Filing of Amendments: Response to Commission Requests. 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 reasonable 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) 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.

(e) Furnishing of Prospectuses. The Company will furnish, upon request, 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.

(f) Blue Sky Qualifications. The Company will arrange for the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution. Notwithstanding the foregoing, the Company shall not be required to qualify as a foreign corporation or take any action that would subject it to general service of process or taxation as a foreign corporation or to take any action that would subject it to general service of process or taxation in any jurisdiction where it is not presently qualified or subject to taxation.

(g) 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 (or any successor system) (“▇▇▇▇▇”), it is not required to furnish such reports or statements to the Underwriters.

(h) 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 any filing fees and other expenses (including the fees and expenses of the Company’s counsel and the Company’s accountants) incurred in connection with qualification of the Offered Securities for sale under the laws of such jurisdictions as the Representatives designate and the preparation and printing of memoranda relating thereto, costs and expenses related to the review by FINRA of the Offered Securities (including filing fees and the fees and expenses of counsel for the Underwriters relating to such review in an amount not greater than $20,000), costs and expenses 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 any aircraft chartered in connection with the road show (except for flights on which there is no

It is understood, however, that, except as provided in this Section 5(h) and Section 8 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).

(i) 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.

(k) Restriction on Sale of Securities by Company. For the period specified below (the “Lock-Up Period”), the Company will not, directly or indirectly, take any of the following actions with respect to its Securities or any securities convertible into or exchangeable or exercisable for any of its Securities (“Lock-Up Securities”): (A) offer, sell, issue, contract to sell, pledge or otherwise dispose of Lock-Up Securities (other than the Offered Securities and shares issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans existing on the date hereof and described in the Initial Registration Statement or General Disclosure Package), (B) offer, sell, issue, contract to sell, contract to purchase or grant any option, right or warrant to purchase Lock-Up Securities (other than the grant of options pursuant to employees, options plans, qualified stock options plans or other employee compensation plans existing on the date hereof and described in the Initial Registration Statement or the General Disclosure Package), (C) enter into any swap, hedge or any other agreement that transfers, in whole or in part, the economic consequences of ownership of Lock-Up Securities, (D) establish or increase a put equivalent position or liquidate or decrease a call equivalent position in Lock-Up Securities within the meaning of Section 16 of the Exchange Act or (E) file with the Commission a registration statement under the Act relating to Lock-Up Securities, or publicly disclose the intention to take any such action, without the prior written consent of the Representatives, except (i) issuances of Lock-Up Securities pursuant to the conversion or exchange of convertible or exchangeable securities or the exercise of warrants or options, in each case outstanding on the date hereof, (ii) the filing of a registration statement on Form S-8 relating to, and the issuance and sale of Lock-Up Securities pursuant to, the terms of the Select Energy Services Inc. 2016 Equity Incentive Plan described in the General Disclosure Package and the Final Prospectus, (iii) the issuance or sale of shares of common stock (up to an aggregate of 10% of the outstanding voting power at the time of such initial issuance) directly to a seller as part of the purchase price in connection with the acquisition of stock or assets of another business, by merger or otherwise, provided that the Company shall cause each recipient of such shares to execute and deliver to the Representatives, on or prior to such issuance, a lock-up agreement with the same terms as the lock-up agreements described above to the extent and for the duration that such terms remain in effect at the time of transfer, and (iv) the filing of a registration statement to register the resale of Securities issuable upon the conversion of shares of Class A-1 common stock.

8. Indemnification and Contribution.

(a) Indemnification of Underwriters by 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 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 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 Section 8(b) below.

(b) Indemnification of Company. 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 and 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, 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 part of any Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus 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 seventh paragraph on the cover of the Final Prospectus; (ii) the concession and reallowance figures appearing in the fifth paragraph under the caption “Underwriting” and (iii) the paragraph relating to the stabilization by the Underwriters under the caption “Underwriting” in the Final Prospectus.

(c) 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 Section 8(a) or (b) 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 Section 8(a) or (b) 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 Section 8(a) or (b) 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.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or (b) 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 Section 8(a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered 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 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 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 bears 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 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 Section 8(d) 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 Section 8(d). Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered 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 Section 8(d) to contribute are several in proportion to their respective underwriting obligations and not joint. The Company 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 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 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 Credit Suisse 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 or the Company, 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 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, 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 hereof, or the occurrence of any event specified in Section 7(c) hereof (other than the occurrence of an event described in Section 7(c)(v)), 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 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, delivered or telegraphed and confirmed to the Representatives, c/o Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: LCD-IBD; c/o FBR Capital Markets & Co., ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, Attention: Compliance Department (fax no: (▇▇▇) ▇▇▇-▇▇▇▇); c/o Wells Fargo Securities, LLC, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, Attention: Equity Syndicate Department (fax no: (▇▇▇) ▇▇▇-▇▇▇▇), or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at 1820 North I-35, P. O. ▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, Attention: ▇▇▇▇ ▇▇▇▇▇▇▇▇.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 7, 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, FBR or ▇▇▇▇▇ Fargo individually, 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 acknowledges and agrees 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, 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 on other matters;

(b) Arms’ Length Negotiations. The price of the Offered Securities set forth in this Agreement was established by Company following discussions and arms-length negotiations with the Representatives, and the Company is 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 has been advised that the Representatives and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Representatives have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

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

If the foregoing is in accordance with the Representatives’ understanding of our agreement, kindly sign and return to the Company one of the counterparts hereof, whereupon it will become a binding agreement among the Company and the several Underwriters in accordance with its terms.

Very truly yours,

Exhibit A

Form of Opinion of Counsel to the Company

1. The Company has been duly incorporated and is validly existing as a corporation and is in good standing under the laws of the State of Delaware with full corporate power and authority to own or lease its properties and to conduct its business, in each case, as described in the Registration Statement, the General Disclosure Package and the Final Prospectus.

2. Each of the Subsidiaries is validly existing as a limited liability company and is in good standing under the laws of its respective jurisdiction of formation with full limited liability company power and authority to own or lease its properties and to conduct its business, in each case, as described in the Registration Statement, the General Disclosure Package and the Final Prospectus. Each of the Subsidiaries is duly registered or qualified to transact business as a foreign limited liability company under the laws of each jurisdiction set forth opposite its name on Schedule A hereto.

3. The Company directly owns such ownership interests in the Subsidiaries as are described in the Registration Statement, the Disclosure Package and the Final Prospectus; such ownership interests have been duly authorized and validly issued in accordance with the respective governing documents of the Subsidiaries and are fully paid (to the extent required) and non-assessable (except as such non-assessability may be limited by sections 18-303, 18-607 and 18-804 of the Delaware Limited Liability Company Act (the “Delaware LLC Act”)); and the Company owns such ownership interests free and clear of all liens, encumbrances or claims (“Liens”) (other than Liens arising under or in connection with the Credit Agreement, as described in the Registration Statement, the Disclosure Package, and the Final Prospectus) (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Company as debtor is on file in the office of the Secretary of State of the State of Delaware as of , 2017 or (ii) otherwise known to us without independent investigation.

4. The Offered Securities to be issued and sold by the Company to the Underwriters under the Underwriting Agreement have been duly authorized in accordance with the Company Charter Documents and, when issued and delivered by the Company to the Underwriters upon payment therefor in accordance with the Underwriting Agreement, will be validly issued in accordance with the Company Charter Documents, free of preemptive rights under federal law, the Delaware General Corporation Law (the “DGCL”) or the Company Charter Documents, fully paid and non-assessable.

5. Except as set forth in the Registration Statement, the General Disclosure Package and the Final Prospectus, there are no persons with registration rights or other similar rights created pursuant to any agreement filed as an exhibit to the Registration Statement to have any securities registered pursuant to the Registration Statement or registered by the Company under the Act or otherwise; and, except as set forth in the Registration Statement, the General Disclosure Package and the Final Prospectus, no options, warrants or other rights to purchase, agreements or other obligations to issue, or convert any obligations into or exchange any securities for, shares of capital stock of or ownership interests in the Company created pursuant to any agreement filed as an exhibit to the Registration Statement are outstanding.

6. 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 Final Prospectus will not, (i) 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; (ii) violate the provisions of the Charter Documents; (iii) violate any federal or New York statute, rule or regulation applicable to the Company or the DGCL or the Delaware LLC Act, or (iv) result in the creation of any additional Lien upon any property or assets of the Company or the Subsidiaries under the Credit Agreement except, with respect to clauses (i), (iii) and (iv), as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; it being understood that we express no opinion in clause (iii) of this paragraph (7) with respect to any federal or state securities, Blue Sky or anti-fraud laws, rules or regulations.

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

8. No consent, approval, authorization or order of, registration or qualification with any federal 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 the 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 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 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.

9. 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.

10. The statements set forth in the General Disclosure Package and Final Prospectus under the headings “Business—Environmental and Occupational Safety and Health Measures,” “Description of Capital Stock,” “Shares Eligible for Future Sale” and “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders” and in the Registration Statement in Item 14, to the extent that they constitute descriptions or summaries of the terms of the Securities 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.

11. The Company is not, and, after giving effect to the offering 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 Registration Statement, the General Disclosure Package and the Final Prospectus under the caption “Use of Proceeds,” will not be, required to register as an “investment company,” as such term is defined in the Investment Company Act and the rules and regulations of the Commission thereunder.

12. The Company has all requisite corporate power and authority to execute, deliver and perform its obligations under the Underwriting Agreement and to issue and sell the Offered Securities.

13. Each of the Registration Statement, as of the Effective Time, the General Disclosure Package, as of the Execution Time, and the Final Prospectus, when filed with the Commission pursuant to Rule 424(b) and at the Closing Date (in each case other than (i) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon and (ii) the other financial data derived therefrom, in each case included in or omitted from the Registration Statement, the General Disclosure Package and the Final Prospectus, as to which we express no opinion), appeared on their face to comply as to form in all material respects with the requirements of the Act.

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 10 above), the accuracy, completeness or fairness of the statements contained in the Registration Statement, the General Disclosure Package and the Final 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, as of the Effective Time (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 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 the light of the circumstances under which they were made, not misleading; or

(c) the Final Prospectus, as of its date or as of the Closing Date, 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, we do 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 any other financial and accounting information, included in the Registration Statement, the General Disclosure Package or the Final Prospectus, and (ii) representations and warranties and other statements of fact included in the exhibits to the Registration Statement.

The restrictions of this Lock-Up Agreement shall not apply to (a) any transactions relating to Securities acquired by the undersigned in the open market after the closing of the offering, (b) any exercise of options or vesting or exercise of any other equity based award, 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 director 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), (d) and (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 Securities Exchange Act of 1934, as amended (the “Exchange Act”) shall be required or shall be voluntarily made in connection with such transfer (other than a filing on a Form 5 made after the expiration of the Lock-Up Period), (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, (g) any transfer or distribution or exchange to affiliates or any transfer under the Registration Rights Agreement with SES Legacy Holdings, LLC filed as Exhibit 4.2 to the Registration Statement, stockholders, partners or members of the undersigned, provided that such stockholders, partners or members agree to be bound in writing by the same restrictions set forth herein, (h) as required by participants in the Company’s 2016 long-term incentive plan solely to the extent necessary to reimburse or pay federal income tax and withholding obligations in connection with vesting of restricted stock grants and (i) as collateral for any loan, provided that the lender agrees in writing to be bound by the same restrictions set forth herein. For purposes of this Lock-Up Agreement, a “family member” shall mean any relationship by blood, marriage, domestic partnership or adoption, not more remote than first cousin.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer 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, the undersigned further agrees that the foregoing restrictions in this Lock-Up Agreement shall be equally applicable to any issuer-directed Securities the undersigned may purchase in the above-referenced offering.

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. Any release or waiver granted by the Representatives 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. 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. Further, this Lock-Up Agreement shall lapse and become null and void if the Public Offering Date shall not have occurred on or before May 1, 2017 or the Underwriting Agreement is terminated. This agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

Very truly yours,
