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 in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation, other than those arising out of the offering or sale of the Shares in any jurisdiction where it is not now so subject.

Section 6. Representations and Agreements of the Company.

(a) The Company represents and agrees that, without the prior consent of Goldman, Sachs & Co., it has not made and will not make any offer relating to the Shares that would constitute a “free writing prospectus” as defined in Rule 405 under the Act; each Underwriter represents and agrees that, without the prior consent of the Company and Goldman, Sachs & Co., it has not made and will not make any offer relating to the Shares that would constitute a free writing prospectus; any such free writing prospectus the use of which has been consented to by the Company and Goldman, Sachs & Co. is listed on Schedule II hereto;

Section 8. Conditions to Obligations of the Underwriters. The obligations of the Underwriters hereunder, as to the Shares to be delivered at each Time of Delivery, shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Company herein are, at and as of such Time of Delivery, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

Section 9. Indemnification.

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

(b) Each Underwriter will, severally and not jointly, indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company by such Underwriter through Goldman, Sachs & Co. expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred. For avoidance of doubt, the Company and each of the Underwriters acknowledge and agree that the only written information furnished to the Company by the Underwriters through the Underwriters are as follows: (i) the discount figure in the fifth paragraph of text under the caption “Underwriting” in the Prospectus; (ii) the third and fourth sentences of the fifth paragraph of text under the caption “Underwriting” in the Prospectus concerning the reoffering terms; and (iii) the seventh paragraph of text under the caption “Underwriting” in the Prospectus concerning short sales, stabilization and purchases to cover short sales by the Underwriters.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel (other than any local counsel) or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party (c) unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them.

(d) No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the

allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company 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 (or actions in respect thereof), 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 (net of underwriting discounts and commissions but before deducting any other expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative 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 on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (e) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (e), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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.

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

Section 10. Default of Underwriters.

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

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

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Company to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof (provided that if such default occurs with respect to Optional Shares after the First Time of Delivery, this Agreement will not terminate as to the Firm Shares or any Optional Shares purchased prior to such termination); but nothing herein shall relieve a defaulting Underwriter from liability for its default.

Section 11. Limitations. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results

thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares.

Anything herein to the contrary notwithstanding, the indemnity agreement of the Company in subsection (a) of Section 9 hereof, the representations and warranties in subsections (b) and (c) of Section 1 hereof and any representation or warranty as to the accuracy of the Registration Statement or the Prospectus contained in any certificate furnished by the Company pursuant to Section 8 hereof, insofar as they may constitute a basis for indemnification for liabilities (other than payment by the Company of expenses incurred or paid in the successful defense of any action, suit or proceeding) arising under the Act, shall not extend to the extent of any interest therein of a controlling person or partner of an Underwriter who is a director, officer or controlling person of the Company when the Registration Statement has become effective, except in each case to the extent that an interest of such character shall have been determined by a court of appropriate jurisdiction as not against public policy as expressed in the Act. Unless in the opinion of counsel for the Company the matter has been settled by controlling precedent, the Company will, if a claim for such indemnification is asserted, submit to a court of appropriate jurisdiction the question of whether such interest is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Section 12. Termination. If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, any Shares are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

Section 13. Representative; Notices; Addresses. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by Goldman, Sachs & Co.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to Goldman, Sachs & Co., 200 West Street, New York, New York 10282-2198, Attention: Registration Department; Phone: 866-471-2526; and if to the Company shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the underwriters are required to obtain, verify and record

information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the underwriters to properly identify their respective clients.

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

Section 16. Arm’s-Length Transaction. The Company acknowledges and agrees that (i) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that the Underwriters, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

Section 17. Agreement Supersedes Prior Understandings. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

Section 18. JURISDICTION AND VENUE. THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK. The Company agrees that any suit or proceeding arising in respect of this agreement or our engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Company agrees to submit to the jurisdiction of, and to venue in, such courts.

Section 19. Waiver of Jury Trial. The Company and each of the Underwriters 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.

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

Section 21. Tax Disclosure. Notwithstanding anything herein to the contrary, the Company is authorized to disclose to any persons the U.S. federal and state income tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Company relating to that treatment and structure, without the Underwriters imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, “tax structure” is limited to any facts that may be relevant to that treatment.

Exhibit A-1

FORM OF OPINION OF COMPANY COUNSEL

a. The Company is validly existing as a corporation, and is in good standing under the laws of the State of Delaware, with the corporate power and authority to own or lease, as the case may be, and to operate its properties and conduct its business as described in the Registration Statement, the Pricing Prospectus and the Prospectus; and is duly qualified to do business as a foreign corporation and is in good standing in New Mexico, Pennsylvania and Texas.

b. Each subsidiary of the Company¹ is validly existing as a limited liability company, limited partnership, or corporation (as applicable) and is in good standing under the laws of its jurisdiction of formation.

c. The Shares to be issued and sold by the Company to the Underwriters under this Agreement have been duly authorized in accordance with the Certificate of Incorporation and Bylaws of the Company (together, the “Governing Documents”) and, when issued and delivered by the Company to the Underwriters upon payment therefor in accordance with this Agreement, will be validly issued in accordance with the Governing Documents, free of preemptive rights under federal law, the Delaware General Corporation Law (the “DGCL”) or the Governing Documents, fully paid and nonassessable.

d. Except as set forth in the Registration Statement, the Pricing Prospectus and the Prospectus, there are no persons with registration rights or other similar rights to have any securities registered pursuant to the Registration Statement or registered by the Company under the Securities Act or otherwise, in each case created pursuant to any agreement filed as an exhibit to the Registration Statement.

e. This Agreement has been duly authorized, executed and delivered by the Company;

f. The execution and delivery of this Agreement by the Company does not, and the offering, issuance and sale of the Shares pursuant to the terms of this Agreement and the application of the proceeds from the sale of the Shares as described under “Use of Proceeds” in the Pricing Prospectus and the 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 Governing Documents or the similar organizational documents of the Company’s subsidiaries²; (iii) violate any federal, New York or Texas statute, rule or regulation applicable to the Company or the DGCL or the Delaware Limited Liability Company Act; or (iv) result in the creation of any lien upon any property or assets of the Company or its subsidiaries pursuant to the terms of any agreement filed as an exhibit to the Registration Statement except, with respect to clauses (i),

¹	Opinion to be limited to TX/DE subsidiaries.

²	Opinion to be limited to TX/DE subsidiaries.

Exhibit A-2 - 1

(iii) and (iv), 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 this Agreement in connection with the offering, issuance and sale of the Shares by the Company (a “Material Adverse Effect”); it being understood that we express no opinion in clause (iii) of this paragraph (f) with respect to any federal or state securities or Blue Sky laws or any federal or state anti-fraud laws, rules or regulations.

g. 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 and delivery by the Company of the Underwriting Agreement and the issuance and sale of the Shares by the Company being delivered on the date hereof pursuant to this Agreement, except (i) as have been obtained or made, (ii) the registration of the offering and sale of the Shares 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 Shares by the Underwriters or (iv) such consents that, if not obtained, have not or would not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

h. The statements made in or incorporated by reference into the Registration Statement, the Pricing Prospectus and the Prospectus under the headings “Business—Government and Environmental Regulation,” “Description of Capital Stock,” and “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders,”, to the extent that they constitute descriptions or summaries of certain terms of the Common Stock or the documents referred to therein, or refer to statements of federal law or the laws of the State of Delaware, are accurate in all material respects.

i. The Company is not, and, after giving effect to the offering and sale of the Shares pursuant to the terms of this Agreement and application of the net proceeds therefrom as described in the Pricing Prospectus and the 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.

j. The Registration Statement has been declared effective under the Act; to our knowledge³, 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 Prospectus pursuant to Rule 424(b) under the Act has been made in the manner and within the time period required by such rule.

k. Each of the Registration Statement, at the time it was declared effective, the Pricing Prospectus, as of the Applicable Time, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) under the Securities Act and at the Time of Delivery (in each case other than (i) the financial statements and related schedules, including the notes and

Exhibit A-2 - 2

schedules thereto and the auditor’s report thereon and (ii) the other financial data derived therefrom and, in each case contained in or omitted from the Registration Statement, or included in or omitted from the Prospectus, as to which we express no opinion), appears on its face to comply as to form in all material respects with the requirements of the Securities Act.

We have participated in conferences with representatives of the Company and with representatives of its independent accountants and counsel for the Underwriters and the independent accountants of Seventy Seven Energy, Inc., at which conferences the contents of the Registration Statement, the Pricing Prospectus and the 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 (h) above), the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Pricing Prospectus 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, as of the latest 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 Pricing Prospectus, 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 Prospectus, as of its date or 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 and (ii) any other financial or accounting information; or any information or estimates derived therefrom, in each case contained in or omitted from the Registration Statement, or included in or omitted from the Pricing Prospectus and the Prospectus.

FORM OF LOCK UP AGREEMENT

January , 2017

Goldman, Sachs & Co.

200 West Street

New York, NY 10282-2198

Re: Patterson-UTI Energy, Inc.

Ladies and Gentlemen:

The undersigned understands that you, as representative (the “Representative”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with Patterson-UTI Energy, Inc., a Delaware corporation (the “Company”), providing for a public offering (the “Offering”) of common stock, par value $0.01 per share, of the Company (the “Shares”) pursuant to a prospectus (the “Prospectus”) to be filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of Common Stock of the Company, or any options or warrants to purchase any shares of Common Stock of the Company, or any securities convertible into, exchangeable for or that represent the right to receive shares of Common Stock of the Company, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Shares. If the undersigned is an officer or director of the issuer, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the Offering.

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue for 60 days after the public offering date set forth on the final prospectus used to sell the Shares (the “Public Offering Date”) pursuant to the Underwriting Agreement.

Exhibit B-1

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, (iii) by will, other testamentary document or intestate succession, provided that any such recipient agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iv) with the prior written consent of the Representative. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the Undersigned’s Shares except in compliance with the foregoing restrictions.

Nothing herein shall prevent any exercise (including a cashless exercise) of options to purchase Shares 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 Registration Statement, the Pricing Prospectus or the Prospectus (each as defined in the Underwriting Agreement), and the withholding of Securities by the Company for the payment of the exercise price or taxes due upon such exercise or vesting, provided that any Shares received upon such exercise or vesting will also be subject to this Lock-Up Agreement.

Anything to the contrary notwithstanding, if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares to be sold thereunder, this Lock-Up Agreement shall lapse and become null and void and the undersigned shall be released from all obligations under this Lock-Up Agreement. The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the Offering.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement. The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

This Lock-Up Agreement and any claim, controversy or dispute arising under or related to this Lock- Up Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the conflict of laws principles thereof.


Sincerely,

Signature:
