NORTHERN TRUST CORPORATION

TERMS AND CONDITIONS
RELATING TO STOCK UNITS GRANTED
PURSUANT TO THE 2017 LONG-TERM INCENTIVE PLAN

1.    Grant of Stock Units.  The Restricted Stock Units (“Stock Units”) with respect to shares of Common Stock of Northern Trust Corporation (the “Corporation”) granted to you pursuant to your Award Notice are subject to these Terms and Conditions Relating to Stock Units Granted Pursuant to the 2017 Long-Term Incentive Plan (the “Terms and Conditions”), the Stock Unit Award Notice (the “Award Notice”) and all of the terms and conditions of the Northern Trust Corporation 2017 Long-Term Incentive Plan (the “2017 Plan”), which is incorporated herein by reference.  In the case of a conflict between these Terms and Conditions, the Award Notice and the terms of the 2017 Plan, the provisions of the 2017 Plan will govern.  Capitalized terms used but not defined herein have the meaning provided therefor in the 2017 Plan.  

2.    Vesting and Settlement; Dividend Equivalents.  Your right to receive the shares of Common Stock issuable pursuant to the Stock Units shall be only as follows:

(a)    Normal Vesting.  If you continue to be an Employee, you will receive the shares of Common Stock underlying the Stock Units that have become vested pursuant to the following vesting schedule (unless otherwise specified in Exhibit I):

	
		
	Vesting Date
	Percentage of Stock Units Vesting

	First anniversary of the Measurement Date
	25%

	Second anniversary of the Measurement Date
	25%

	Third anniversary of the Measurement Date
	25%

	Fourth anniversary of the Measurement Date
	25%

(b)    Cause.  Notwithstanding anything to the contrary contained in these Terms and Conditions, if your Employer terminates your employment for Cause, your Stock Units, whether vested but unsettled or unvested, immediately shall terminate and be forfeited.

(c)    Disability and Death.  If you cease to be an Employee by reason of Disability or death prior to the date that your Stock Units become fully vested, you or your estate will become fully vested in your Stock Units, and you, your legal representative or your estate will receive all of the underlying shares of Common Stock.

(d)    Retirement.  If you cease to be an Employee by reason of Retirement prior to the date that your Stock Units become fully vested, you will continue to vest in your unvested 

Page 1

Stock Units pursuant to Section 2(a) above and once vested, you will receive the underlying shares of Common Stock pursuant to the Stock Units that become vested hereunder following the originally contemplated Vesting Date(s).  However, if you cease to be Retired from the Industry (as determined by the Committee in its sole discretion), any Stock Units (whether vested but unsettled or unvested) immediately shall terminate and be forfeited. Notwithstanding the foregoing, you will continue to vest in your unvested Stock Units pursuant to this Section 2(d) regardless of whether you cease to be Retired from the Industry if (i) your termination qualifies as a Mutual Agreement Termination, or (ii) a forfeiture upon your ceasing to be Retired from the Industry would violate applicable law. 

(e)    Mutual Agreement Termination.  If you cease to be an Employee prior to the date that your Stock Units become fully vested and your termination qualifies as a Mutual Agreement Termination, you will continue to vest in your unvested Stock Units pursuant to Section 2(a) above and once vested, you will receive the underlying shares of Common Stock pursuant to the Stock Units that become vested hereunder following the originally contemplated Vesting Date(s).

(f)    Other Termination Events.  If you cease to be an Employee prior to the date that your Stock Units become fully vested for any reason other than those provided above, you shall cease vesting in your Stock Units effective as of your Termination Date and any unvested Stock Units immediately shall terminate and be forfeited.

(g)    Form and Timing of Settlement.  Notwithstanding the foregoing, the Corporation may, in its sole discretion, settle your Stock Units in the form of: (i) a cash payment to the extent settlement in shares of Common Stock (1) is prohibited under local law, (2) would require you or the Corporation to obtain the approval of any governmental and/or regulatory body in your country of residence (and/or country of employment, if different) or (3) is administratively burdensome or (ii) shares of Common Stock, but require you to immediately sell such shares of Common Stock (in which case, the Corporation shall have the authority to issue sales instructions in relation to such shares of Common Stock on your behalf).  Also, the Stock Units shall be settled as soon as administratively practicable following the applicable Vesting Date (but in no event later than 60 days following the applicable Vesting Date).

(h)    Dividend Equivalents.  Upon the payment of any dividend on the shares of Common Stock occurring during the period preceding the settlement of your Stock Units pursuant to these Terms and Conditions, the Corporation shall credit to you an amount in cash equal in value to the dividends that you would have received had you been the actual owner of the number of shares of Common Stock represented by the Stock Units.  The payment of any dividend equivalents as provided herein shall be made as soon as administratively practicable following the originally contemplated Vesting Date(s) (but in no event later than 60 days following the applicable Vesting Date).

3.    Treatment Upon Change in Control.  

(a)     General.  Except as may be otherwise provided in an agreement executed by the Corporation (and, where applicable, approved by the Corporation’s shareholders) addressing a Change in Control and which does not materially impair your rights under the Stock Units, your 

Page 2

Stock Units shall be treated in accordance with the following provisions in the event of a Change in Control. 
(b)    Conversion of Stock Units.  In the event of a Change in Control, the outstanding Stock Units (“Northern Trust Stock Units”) shall be converted into a Replacement Award.  Upon a Qualifying Termination, the Replacement Award shall become fully vested and the acquirer shall issue you shares of acquirer’s common stock in settlement of such Replacement Award as soon as administratively practicable following such Qualifying Termination (but in no event later than 60 days following the Qualifying Termination).  For purposes of the foregoing and to the extent possible, the conversion of Northern Trust Stock Units into a Replacement Award shall be effectuated in accordance with the applicable provisions of the Code (and the related Treasury Regulations) and the applicable provisions of the laws of your country of residence and/or country of employment such that the conversion is tax neutral and itself does not trigger a taxable event to you, the Corporation, your Employer or the acquirer.
(c)    Cashout of Stock Units.  In the event of a Change in Control where the acquirer does not convert Northern Trust Stock Units into a Replacement Award, the Corporation shall fully vest each Northern Trust Stock Unit immediately prior to the Change in Control, and then shall cancel each such vested Northern Trust Stock Unit in exchange for a cash payment equal to the aggregate consideration paid to each shareholder of one (1) share of Common Stock upon the Change in Control.  Such cash payment shall be made as soon as administratively practicable following the Change in Control (but in no event later than 60 days following the Change in Control) in such manner and in accordance with such procedures as the Committee may determine in its sole discretion.
4.    Legal and Tax Compliance; Cooperation.  If you are resident and/or employed outside of the United States, you agree, as a condition of the grant of the Stock Units, to repatriate all payments attributable to the shares of Common Stock and/or cash acquired under the 2017 Plan (including, but not limited to, dividends, dividend equivalents and any proceeds derived from the sale of the shares of Common Stock acquired pursuant to the Stock Units) if required by and in accordance with local foreign exchange rules and regulations in your country of residence (and/or country of employment, if different).  In addition, you also agree to take any and all actions, and consent to any and all actions taken by the Corporation and its Subsidiaries, as may be required to allow the Corporation and its Subsidiaries to comply with local laws, rules and regulations in your country of residence (and/or country of employment, if different).  Finally, you agree to take any and all actions as may be required to comply with your personal legal and tax obligations under local laws, rules and regulations in your country of residence (and/or country of employment, if different).

5.    Age Discrimination Rules.  If you are resident and/or employed in a country that is a member of the European Union, the grant of the Stock Units and these Terms and Conditions are intended to comply with the Age Discrimination Rules.  To the extent that a court or tribunal of competent jurisdiction determines that any provision of the Terms and Conditions are invalid or unenforceable, in whole or in part, under the Age Discrimination Rules, the Corporation, in its sole discretion, shall have the power and authority to revise or strike such provision to the minimum 

Page 3

extent necessary to make it valid and enforceable to the full extent permitted under local law.

6.    Withholding of Tax-Related Items.  

(a)    Regardless of any action the Corporation and/or your Employer take with respect to any or all Tax-Related Items, you acknowledge that the ultimate liability for all Tax-Related Items legally due by you is and remains your responsibility and that the Corporation and your Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Stock Units, including the grant of the Stock Units, the vesting of the Stock Units, the subsequent sale of any shares of Common Stock acquired pursuant to the Stock Units and the receipt of any dividends or dividend equivalents and (ii) do not commit to structure the terms of the grant or any aspect of the Stock Units to reduce or eliminate your liability for Tax-Related Items.

(b)    Prior to the delivery of shares of Common Stock upon the vesting of your Stock Units, if your country of residence (and/or country of employment, if different) requires withholding of Tax-Related Items, the Corporation shall withhold a sufficient number of whole shares of Common Stock otherwise issuable upon the vesting of the Stock Units that have an aggregate Fair Market Value sufficient to pay the Tax-Related Items required to be withheld with respect to the shares of Common Stock.  The cash equivalent of the shares of Common Stock withheld will be used to settle the obligation to withhold the Tax-Related Items.  In the event that withholding in shares of Common Stock is prohibited or problematic under applicable law or otherwise may trigger adverse consequences to the Corporation or your Employer, your Employer may withhold the minimum Tax-Related Items required to be withheld with respect to the shares of Common Stock in cash from your regular salary and/or wages or any other amounts payable to you.  In the event the withholding requirements are not satisfied through the withholding of shares of Common Stock by the Corporation or through your regular salary and/or wages or other amounts payable to you by your Employer, no shares of Common Stock will be issued to you (or your estate) upon vesting of the Stock Units unless and until satisfactory arrangements (as determined by the Corporation) have been made by you with respect to the payment of any Tax-Related Items that the Corporation or your Employer determines, in its sole discretion, must be withheld or collected with respect to such Stock Units.  

(c)    By accepting these Stock Units, you expressly consent to the foregoing methods of withholding as provided for hereunder.  All other Tax-Related Items related to the Stock Units and any shares of Common Stock delivered in settlement thereof are your sole responsibility.

7.    Code Section 409A.  

(a)    The Stock Units are intended to comply with or be exempt from the requirements of Code Section 409A.  The 2017 Plan and these Terms and Conditions shall be administered and interpreted in a manner consistent with this intent.  If the Corporation determines that these Terms and Conditions are subject to Code Section 409A and that they do not comply with or are inconsistent with the applicable requirements, the Corporation may, in its sole discretion, and 

Page 4

without your consent, amend these Terms and Conditions to cause them to comply with Code Section 409A or be exempt from Code Section 409A.

(b)    Notwithstanding any provision of these Terms and Conditions to the contrary, in the event that any settlement or payment of the Stock Units occurs as a result of your termination of employment and the Corporation determines that you are a “specified employee” (within the meaning of Code Section 409A) subject to Code Section 409A at the time of your termination of employment, and provided further that such payment or settlement does not otherwise qualify for an applicable exemption from Code Section 409A, then no such settlement or payment shall be paid to you until the date that is the earlier to occur of: (i) your death, or (ii) six (6) months and one (1) day following your termination of employment.  Any portion of the Stock Units where settlement is delayed as a result of the foregoing, which is (i) in whole or in part, settled in cash and (ii) based on the value of a share of Common Stock, shall be based on the value of a share of Common Stock at the time the Stock Units otherwise would have been settled or paid without application of the delay described in the foregoing sentence.  If the Stock Units do not otherwise qualify for an applicable exemption from Code Section 409A, the terms “Retirement,” “terminate,” “termination,” “termination of employment,” and variations thereof as used in these Terms and Conditions are intended to mean a “separation from service” as such term is defined under Code Section 409A.

(c)    Although these Terms and Conditions and the payments provided hereunder are intended to be exempt from or to otherwise comply with the requirements of Code Section 409A, the Corporation does not represent or warrant that these Terms and Conditions or the payments provided hereunder will comply with Code Section 409A or any other provisions of federal, state, local, or non-U.S. law.  Neither the Corporation, its Subsidiaries, your Employer or their respective directors, officers, employees or advisers shall be liable to you (or any other individual claiming a benefit through you) for any tax, interest, or penalties you may owe as a result of compensation paid under these Terms and Conditions, and the Corporation, its Subsidiaries and your Employer shall have no obligation to indemnify or otherwise protect you from the obligation to pay any taxes pursuant to Code Section 409A.

8.    Forfeitures and Recoupment 

(a)    Recoupment Policy.  In addition to these Terms and Conditions, your Stock Units and any shares of Common Stock issued to you pursuant to the Stock Units shall be subject to the provisions of the Northern Trust Corporation Policy on Recoupment, as may be subsequently amended from time to time (the “Policy”).

(b)    Delegation of Authority to Corporation.  For purposes of the foregoing, you expressly and explicitly authorize the Corporation to issue instructions, on your behalf, to any brokerage firm and/or third party administrator engaged by the Corporation to hold your shares of Common Stock and other amounts acquired pursuant to your Stock Units to re-convey, transfer or otherwise return such shares of Common Stock and/or other amounts to the Corporation upon the Corporation's enforcement of the Policy.  To the extent that these Terms and Conditions and the Policy conflict, the terms of the Policy shall prevail.

Page 5

9.    Nontransferability.  The Stock Units shall be transferable only by will or the laws of descent and distribution.  If you purport to make any transfer of the Stock Units, except as aforesaid, the Stock Units and all rights thereunder shall terminate immediately.

10.    Securities Laws.  The Stock Units shall not be vested in whole or in part, and the Corporation shall not be obligated to issue any shares of Common Stock subject to the Stock Units, if such issuance would, in the opinion of counsel for the Corporation, violate the Securities Act of 1933 or any other U.S. federal, state or non-U.S. laws having similar requirements as may be in effect at the time. The Stock Units are subject to the further requirement that, if at any time the Board of Directors of the Corporation shall determine in its discretion that the listing or qualification of the shares of Common Stock subject to the Stock Units under any securities exchange requirements or under any applicable law, or the consent or approval of any governmental regulatory body, is necessary or desirable as a condition of or in connection with the issuance of shares of Common Stock pursuant to the Stock Units, the Stock Units may not be vested in whole or in part unless such listing, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable to the Corporation.

11.    No Right of Continued Employment.  The grant of the Stock Units shall not confer upon you any right to continue in the employ of your Employer nor limit in any way the right of your Employer to terminate your employment at any time.  You shall have no rights as a shareholder of the Corporation with respect to any shares of Common Stock issuable upon the vesting of the Stock Units until the date of issuance of such shares of Common Stock.

12.     Discretionary Nature; No Vested Rights.  You acknowledge and agree that the 2017 Plan is discretionary in nature and may be amended, cancelled, or terminated by the Corporation, in its sole discretion, at any time.  The grant of the Stock Units under the 2017 Plan is a one-time benefit and does not create any contractual or other right to receive a grant of Stock Units or any other award under the 2017 Plan or other benefits in lieu thereof in the future.  Future grants, if any, will be at the sole discretion of the Corporation, including, but not limited to, the form and timing of any grant, the number of shares of Common Stock subject to the grant, and the vesting provisions. Any amendment, modification or termination of the 2017 Plan shall not constitute a change or impairment of the terms and conditions of your employment with your Employer.

13.    Extraordinary Benefit.  Your participation in the 2017 Plan is voluntary.  The value of the Stock Units and any other awards granted under the 2017 Plan is an extraordinary item of compensation outside the scope of your employment (and your employment contract, if any).  Any grant under the 2017 Plan, including the grant of the Stock Units, is not part of normal or expected compensation for purposes of calculating any severance, resignation, redundancy, end of service payments, bonuses, long-service awards, pension, or retirement benefits or similar payments.

14.    Heirs.  These Terms and Conditions shall bind and inure to the benefit of the Corporation, its successors and assigns, and you and your estate in the event of your death.

15.    Personal Data.  The Corporation and your Employer hereby notify you of the following in relation to your personal data and the collection, processing and transfer of such data 

Page 6

in relation to the grant of the Stock Units and your participation in the 2017 Plan pursuant to applicable personal data protection laws. The collection, processing and transfer of your personal data is necessary for the Corporation’s administration of the 2017 Plan and your participation in the 2017 Plan, and your denial and/or objection to the collection, processing and transfer of personal data may affect your ability to participate in the 2017 Plan. As such, you voluntarily acknowledge, consent and agree (where required under applicable law) to the collection, use, processing and transfer of personal data as described herein.  

The Corporation and your Employer hold certain personal information about you, including (but not limited to) your name, home address, email address and telephone number, date of birth, social security number or other employee identification number, salary, nationality, job title, any shares of Common Stock or directorships held in the Corporation, details of all Stock Units or any other entitlement to shares of Common Stock awarded, canceled, purchased, vested, unvested or outstanding in your favor for the purpose of managing and administering the 2017 Plan (the “Data”).  The Data may be provided by you or collected, where lawful, from third parties, and the Corporation and your Employer will process the Data for the exclusive purpose of implementing, administering and managing your participation in the 2017 Plan.  The data processing will take place through electronic and non-electronic means according to logics and procedures strictly correlated to the purposes for which the Data is collected and with confidentiality and security provisions as set forth by applicable laws and regulations in your country of residence (and/or country of employment, if different).  Data processing operations will be performed minimizing the use of personal and identification data when such information is unnecessary for the processing purposes sought.  The Data will be accessible within the Corporation’s organization only by those persons requiring access for purposes of implementation, administration and operation of the 2017 Plan and for your participation in the 2017 Plan.

The Corporation and your Employer will transfer the Data as necessary for the purpose of implementation, administration and management of your participation in the 2017 Plan, and the Corporation and your Employer may each further transfer the Data to any third parties assisting the Corporation in the implementation, administration and management of the 2017 Plan.  These recipients may be located in the European Economic Area, the United States or elsewhere throughout the world.  You hereby authorize (where required under applicable law) the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for purposes of implementing, administering and managing your participation in the 2017 Plan, including any requisite transfer of such Data as may be required for the administration of the 2017 Plan and/or the subsequent holding of shares of Common Stock on your behalf to a broker or other third party with whom you may elect to deposit any shares of Common Stock acquired pursuant to the 2017 Plan.  

You may, at any time, exercise your rights provided under applicable personal data protection laws, which may include the right to (a) obtain confirmation as to the existence of the Data, (b) verify the content, origin and accuracy of the Data, (c) request the integration, update, amendment, deletion or blockage (for breach of applicable laws) of the Data and (d) oppose, for legal reasons, the collection, processing or transfer of the Data that is not necessary or required for implementation, administration and/or operation of the 2017 Plan and your participation in the 2017 Plan.  You may seek to exercise these rights by contacting your local HR manager.

Page 7

Finally, upon request of the Corporation or your Employer, you agree to provide an executed data privacy consent to the Corporation and/or your Employer (or any other agreements or consents that may be requested by the Corporation and/or your Employer) that the Corporation and/or your Employer may deem necessary or appropriate for the purpose of administering your participation in the 2017 Plan in accordance with the data privacy laws in your country of residence (and/or country of employment, if different), either now or in the future. You understand and agree that you will be unable to participate in the 2017 Plan if you fail to provide such consent or agreement requested by the Corporation or your Employer.

16.    Private Placement.  If you are a resident and/or employed outside of the United States, you acknowledge that the grant of the Stock Units is not intended to be a public offering of securities in your country of residence (and/or country of employment, if different).  You further acknowledge that the Corporation has not submitted any registration statement, prospectus or other filing with any securities authority other than the U.S. Securities and Exchange Commission with respect to the grant of the Stock Units, unless otherwise required under local law.  No employee of the Corporation is permitted to advise you on whether you should acquire shares of Common Stock under the 2017 Plan or provide you with any legal, tax or financial advice with respect to the grant of the Stock Units.  The acquisition of shares of Common Stock involves certain risks, and you should carefully consider all risk factors and tax considerations relevant to the acquisition of shares of Common Stock under the 2017 Plan and the disposition of them.  Further, you should carefully review all of the materials related to the Stock Units and the 2017 Plan, and you should consult with your personal legal, tax and financial advisors for professional advice in relation to your personal circumstances.

17.    Governing Law.  All questions concerning the construction, validity and interpretation of the Stock Units and the 2017 Plan shall be governed and construed according to the laws of the state of Delaware, without regard to the application of the conflicts of laws provisions thereof.  Any disputes regarding the Stock Units or the 2017 Plan shall be brought only in the state or federal courts of the state of Delaware.

18.    Electronic Delivery.  The Corporation may, in its sole discretion, decide to deliver any documents related to the Stock Units or other awards granted to you under the 2017 Plan by electronic means.  You hereby consent to receive such documents by electronic delivery and agree to participate in the 2017 Plan through an on-line or electronic system established and maintained by the Corporation or a third party designated by the Corporation.

19.    Severability.  The invalidity or unenforceability of any provision of the 2017 Plan or these Terms and Conditions shall not affect the validity or enforceability of any other provision of the 2017 Plan or these Terms and Conditions.  

20.    English Language.  If you are resident and/or employed outside of the United States, you acknowledge and agree that it is your express intent that these Terms and Conditions, the 2017 Plan and all other documents, notices and legal proceedings entered into, given or instituted pursuant to the Stock Units be drawn up in English.  If you have received these Terms and Conditions, the 

Page 8

2017 Plan or any other documents related to the Stock Units translated into a language other than English and the meaning of the translated version is different than the English version, the English version will control.  

21.    Addendum.  Notwithstanding any provisions of these Terms and Conditions to the contrary, the Stock Units shall be subject to any special terms and conditions for your country of residence (and/or country of employment, if different) set forth in an addendum to these Terms and Conditions (an “Addendum”).  Further, if you transfer your residence and/or employment to another country reflected in an Addendum to these Terms and Conditions at the time of transfer, the special terms and conditions for such country will apply to you to the extent the Corporation determines, in its sole discretion, that the application of such special terms and conditions is necessary or advisable in order to comply with local law, rules and regulations or to facilitate the operation and administration of the Stock Units and the 2017 Plan (or the Corporation may establish alternative terms and conditions as may be necessary or advisable to accommodate your transfer).  In all circumstances, any applicable Addendum shall constitute part of these Terms and Conditions.
22.    Insider Trading.  By participating in the 2017 Plan, you expressly agree to comply with the Corporation’s Securities Transactions Policy and Procedures and any other of its policies regarding insider trading or personal account dealing applicable to you. Further, you expressly acknowledge and agree that, depending on the country of residence of you or your broker, or where the shares of Common Stock are listed, you may be subject to insider trading restrictions and/or market abuse laws which may affect your ability to accept, acquire, sell or otherwise dispose of shares of Common Stock, rights to shares of Common Stock (e.g., Stock Units) or rights linked to the value of the shares of Common Stock, during such times you are considered to have material non-public information, “inside information” or similar types of information regarding the Corporation as defined by laws or regulations in the applicable country. Local insider trading laws and regulations may prohibit the cancellation or amendment of orders you place before you possessed such information.  Furthermore, you may be prohibited from (a) disclosing such information to any third party (other than on a “need to know” basis) and (b) “tipping” third parties or causing them otherwise to buy or sell securities (including other employees of the Corporation and its Subsidiaries). Any restriction under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Corporation policies. You expressly acknowledge and agree that it is your responsibility to comply with any applicable restrictions, and you should consult your personal advisor for additional information on any trading restrictions that may apply to you.
23.    Additional Requirements; Amendments.  The Corporation reserves the right to impose other requirements on the Stock Units, any shares of Common Stock acquired pursuant to the Stock Units and your participation in the 2017 Plan to the extent the Corporation determines, in its sole discretion, that such other requirements are necessary or advisable in order to comply with local law, rules and regulations or to facilitate the operation and administration of the Stock Units and the 2017 Plan.  Such requirements may include (but are not limited to) requiring you to sign any agreements or undertakings that may be necessary to accomplish the foregoing. In addition, the Corporation reserves the right to amend these Terms and Conditions, without your consent,

either prospectively or retroactively, to the extent that such amendment does not materially impair your rights under the Stock Units.

The Representative shall have received on and as of the Closing Date an opinion of DLA Piper LLP, Credit Agreement counsel for the Company to the effect that none of the execution and delivery of, or the incurrence or performance by the Company and the Guarantors of their respective obligations under, each of the Transaction Documents to which the Company or any Guarantor is a party, each in accordance with its terms, (i) constituted, constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under the Credit Agreement or (ii) resulted, results or will result in the creation of any security interest in, or lien upon, any of the property or assets of the Company or the Guarantors pursuant to the Credit Agreement, except for any contravention which would not have a Material Adverse Effect. 
(j)    No Legal Impediment to Issuance. No action shall have been taken and no statute, rule, regulation or order shall have been enacted, adopted or issued by any federal, state or foreign governmental or regulatory authority that would, as of the Closing Date, prevent the issuance or sale of the Securities or the issuance of the Guarantees; and no injunction or order of any federal, state or foreign court shall have been issued that would, as of the Closing Date, prevent the issuance or sale of the Securities or the issuance of the Guarantees.
(k)    Good Standing. The Representative shall have received on and as of the Closing Date satisfactory evidence of the good standing of the Company and the Guarantors in their respective jurisdictions of organization and their qualification and good standing in such other jurisdictions in which the conduct of the Company’s and its subsidiaries’ business or ownership or leasing of property or assets requires such qualification (such jurisdictions being set forth in Schedule 3 hereto opposite the name of each Guarantor), in each case in writing or any standard form of telecommunication, from the appropriate governmental authorities of such jurisdictions.
(l)    Indenture. The Company, the Guarantors and the Trustee shall have entered into the Indenture in form and substance reasonably satisfactory to the Representative, and the 

23

Representative shall have received a counterpart of the Indenture that shall have been executed and delivered by the Trustee and a duly authorized officer of the Company and each of the Guarantors.

The Company shall have furnished to the Representative on the date hereof a certificate, signed by the Chief Financial Officer substantially in the form set forth on Exhibit B hereto (the “Initial CFO Certificate”).  On or prior to the Closing Date or any Additional Closing Date, as the case may be, the Representative shall have received from the Chief Financial Officer of the Company a certificate (the “Bring-Down CFO Certificate”) (i) stating, as of the date of the Bring-Down CFO Certificate (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Offering Memorandum, as of a date not more than three days prior to the date of the Bring-Down CFO Certificate), the conclusions and findings of the Chief Financial Officer with respect to the financial information and other matters covered by the Initial CFO Certificate and (ii) confirming in all material respects the conclusions and findings set forth in the Initial CFO Certificate.
(o)    Additional Documents. On or prior to the Closing Date, the Company and the Guarantors shall have furnished to the Representative such further certificates and documents as the Representative may reasonably request.
All opinions, letters, certificates and evidence mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Initial Purchasers.
4.    Indemnification and Contribution.
(a)    Indemnification of the Initial Purchasers. The Company and each of the Guarantors jointly and severally agree to indemnify and hold harmless each Initial Purchaser, its affiliates and agents who have, or who are alleged to have, participated in the distribution of Securities, directors and officers and each person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) such Initial Purchaser, and the successors and assigns of all the foregoing persons, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained or incorporated by reference in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto) or any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged 

24

untrue statement or omission made in reliance upon and in conformity with any information relating to any Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Initial Purchaser consists of the information described as such in paragraph (b) below.
(b)    Indemnification of the Company. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Company, each of the Guarantors, each of their respective directors and officers and each person, if any, who controls the Company or any of the Guarantors (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Initial Purchaser furnished to the Company in writing by such Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any of the other Time of Sale Information, any Issuer Written Communication or the Offering Memorandum (or any amendment or supplement thereto), it being understood and agreed that the only such information consists of the following: the information contained in the third and fourth sentences of the eleventh paragraph and the fourteenth paragraph, respectively, under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum.
(c)    Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (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 Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed in writing to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person 

25

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 Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the reasonably incurred fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Initial Purchaser, its affiliates, agents, directors and officers and any control persons of such Initial Purchaser shall be designated in writing by the Representative and any such separate firm for the Company, the Guarantors, their respective directors and officers and any control persons of the Company and the Guarantors shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent (which shall not be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph (c), the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (1) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (2) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person (which shall not be unreasonably withheld), effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.
(d)    Contribution. If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Initial Purchasers 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 Guarantors on the one hand and the Initial 

26

Purchasers on the other in connection with the statements or omissions that 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 Guarantors on the one hand and the Initial Purchasers on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Initial Purchasers in connection therewith, as provided in this Agreement, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Guarantors on the one hand and the Initial Purchasers on the other 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 any Guarantor or by the Initial Purchasers and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.
(e)    Limitation on Liability. The Company, the Guarantors and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Initial Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Initial Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Initial Purchaser with respect to the offering of the Securities exceeds the amount of any damages that such Initial Purchaser 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Initial Purchasers’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.
(f)    Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.
5.    Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.
6.    Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, on or by any of the New York Stock Exchange, the Nasdaq Global Select Market or 

27

the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred; (iv) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; (v) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum; or (vi) there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Time of Sale Information or the Offering Memorandum, any change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Company and its subsidiaries, taken as a whole, whether or not arising in the ordinary course of business, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Offering Memorandum.
7.    Defaulting Initial Purchaser.
(a)    If, on the Closing Date, any Initial Purchaser defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Initial Purchasers may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Initial Purchaser, the non-defaulting Initial Purchasers do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Initial Purchasers to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Initial Purchaser, either the non-defaulting Initial Purchasers or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Initial Purchasers may be necessary in the Time of Sale Information, the Offering Memorandum or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Time of Sale Information or the Offering Memorandum that effects any such changes. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.
(b)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all 

28

the Securities, then the Company shall have the right to require each non-defaulting Initial Purchaser to purchase the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder plus such Initial Purchaser’s pro rata share (based on the principal amount of Securities that such Initial Purchaser agreed to purchase hereunder) of the Securities of such defaulting Initial Purchaser or Initial Purchasers for which such arrangements have not been made.
(c)    If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Initial Purchaser or Initial Purchasers by the non-defaulting Initial Purchasers and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Initial Purchasers. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.
(d)    Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Company, the Guarantors or any non-defaulting Initial Purchaser for damages caused by its default.
8.    Payment of Expenses.
(a)    Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and each of the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any transfer fees or taxes payable in connection therewith; (ii) the costs incident to the preparation, printing of the Preliminary Offering Memorandum, any other Time of Sale Information, any Issuer Written Communication and the Offering Memorandum (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s and the Guarantors’ counsel, the independent accountants and reserve engineers; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Initial Purchasers); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, FINRA, and the approval of the Securities for book-entry transfer by DTC; and (ix) all expenses incurred by the Company in connection with any “road show” 

29

presentation to potential investors (including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants; provided that notwithstanding clause (ix) above, the Initial Purchasers shall pay one-half of the lease expenses associated with any airplane which is used in connection with such “road show” presentations.
(b)    If (i) this Agreement is terminated pursuant to clauses (ii) or (vi) of Section 9, (ii) the Company for any reason fails to tender the Securities for delivery to the Initial Purchasers or (iii) the Initial Purchasers decline to purchase the Securities for any reason permitted under this Agreement, the Company and each of the Guarantors jointly and severally agrees to reimburse the Initial Purchasers for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the offering contemplated hereby.
9.    Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, agents, officers and directors of each Initial Purchaser referred to in Section 7 hereof. Except as provided in Section 1(c) or to the extent any party may be entitled to indemnification pursuant to Section 7, nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor merely by reason of such purchase.
10.    Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Guarantors and the Initial Purchasers contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Initial Purchasers pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Guarantors or the Initial Purchasers.
11.    Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “Exchange Act” means the Securities Exchange Act of 1934, as amended; (d) except where otherwise expressly provided, the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (e) the term “written communication” has the meaning set forth in Rule 405 under the Securities Act.
12.    USA Patriot Act. The Company and each of the Guarantors acknowledges that, in accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into 

30

law October 26, 2001)), the Initial Purchasers 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 Initial Purchasers to properly identify their respective clients.
13.    Waiver of Jury Trial. The Company, the Guarantors and each of the Initial Purchasers 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.
14.    Consent to Jurisdiction.  The Company, the Guarantors and each Initial Purchaser hereby submits to the non-exclusive jurisdiction of any U.S. federal or state court located in the Borough of Manhattan, the City and County of New York in any action, suit or proceeding arising out of or relating to or based upon this Agreement or any of the transactions contemplated hereby, and the Company, the Guarantors and each Initial Purchaser irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding in any such court arising out of or relating to this Agreement or the transactions contemplated hereby and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding has been brought in an inconvenient forum.  
15.    Miscellaneous.

The Company has the corporate power and corporate authority under the laws of the State of Delaware to (a) execute and deliver, and incur and perform all of its obligations under, the Purchase Agreement, the Indenture and the Securities (collectively the “Transaction Documents”) and (b) carry on its business and own its properties as described in the Time of Sale Information and the Offering Memorandum. Each of the Guarantors has the limited liability company power and authority under the laws of the State of Delaware to (i) execute and deliver, and to incur and perform all of its obligations under, the Transaction Documents to which it is a party and (ii) carry on its business and own its properties as described in the Time of Sale Information and the Offering Memorandum.
3.    Each of the Transaction Documents has been duly authorized, executed and delivered by the Company. Each of the Purchase Agreement and the Indenture has been duly authorized, executed and delivered by each of the Guarantors. The Guarantees included in the Indenture have been duly authorized by each of the Guarantors.
4.    None of the execution and delivery of, or the incurrence or performance by, the Company and the Guarantors (collectively, the “Obligors”) of their respective obligations under, each of the Transaction Documents to which it is a party, each in accordance with its terms, (a) constituted, constitutes or will constitute a violation under any provision of the Delaware Limited Liability Company Act, Delaware General Corporation Law, Regulation T, U or X of the Board of Governors of the Federal Reserve System or the applicable laws of the State of Texas, State of New York or U. S. federal law, (b) constituted, constitutes or will constitute a violation under the certificate of incorporation, certificate of formation, bylaws, operating agreement or limited liability company agreement or any other formation or governing document of the Company or the Guarantors, (c) constituted, constitutes, or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under any agreement or other instrument binding upon the Company or any of the Subsidiaries, other than the Credit Agreement, filed as an exhibit to the Company’s Form 10-K for the year ended December 31, 2017 or to any Form 8-K of the Company filed since the filing of such Annual Report on Form 10-K (the “Applicable Agreements”), (d) resulted, results or will result in the creation of any security interest in, or lien upon, any of the property or assets of any Obligor pursuant to any of the Applicable Agreements, 

Exhibit A

5.    No consent, approval, authorization or order of, or qualification or filing with, any governmental body or agency is required for the execution and delivery by each of the Company and the Guarantors of, or the performance or incurrence by the Company or the Guarantors of their respective obligations under, the Transaction Documents or the consummation of the transactions thereunder, except (a) as have been or will be obtained or made on or prior to the Closing Date, or (b) where the failure to obtain such consent, approval, authorization, order or qualification would not reasonably be expected to have a Material Adverse Effect or materially impair the ability of the Company and Guarantors to consummate the transactions contemplated by the Transaction Documents.
6.    The statements under the caption “Description of Notes” in the Preliminary Offering Memorandum as supplemented by the Pricing Term Sheet and in the Offering Memorandum, insofar as such statements purport to summarize the Indenture and the Securities, fairly summarize the Indenture and the Securities in all material respects, subject to the qualifications and assumptions stated therein.
7.    The statements in the Preliminary Offering Memorandum and the Offering Memorandum under the caption “Certain United States Federal Income Tax Considerations,” insofar as they refer to statements of law or legal conclusions, fairly summarize the matters referred to therein in all material respects, subject to the qualifications and assumptions stated therein.
8.    The Indenture constitutes a valid and binding obligation of each of the Obligors, enforceable against each of them in accordance with its terms, under the laws of the State of New York, except as such enforceability may be limited by the Enforceability Exceptions; and the Indenture conforms in all material respects with the requirements of the Trust Indenture Act and the rules and regulations of the Commission applicable to an indenture that is qualified thereunder.
9.    When authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the Purchase Agreement, the Securities will constitute valid and binding obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms, under the laws of the State of New York, except as such enforceability may be limited by the Enforceability Exceptions.

Exhibit A

10.    When the Securities have been authenticated by the Trustee in the manner provided in the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the Purchase Agreement, the guarantees of the Securities included in the Indenture will constitute a valid and binding obligation of the Guarantors, enforceable against the Guarantors in accordance with the terms of the Indenture, under the laws of the State of New York, except as such enforceability may be limited by the Enforceability Exceptions.
11.    Assuming the accuracy of the representations, warranties and covenants of the Company, Guarantors and Initial Purchasers set forth in Sections 1(b), 3(mm), 3(nn), 4 and 5 in the Purchase Agreement, the offer, issue, sale and delivery of the Securities (and the guarantees thereof by the Guarantors) to the Initial Purchasers and the initial resale of the Securities (and the guarantees thereof by the Guarantors) by the Initial Purchasers, each in the manner contemplated by the Purchase Agreement and the Offering Memorandum, do not require registration under the Securities Act, and such offer, issue, sale and delivery of the Securities (and the guarantees thereof by the Guarantors) and such initial resale of the Securities (and the guarantees thereof by the Guarantors) do not require qualification of the Indenture under the Trust Indenture Act; provided, however, that we express no opinion as to any subsequent resale of any Security (and the guarantees thereof by the Guarantors).
12.    The Company and the Guarantors are not, and immediately after giving effect to the issuance and sale of the Securities pursuant to the Purchase Agreement and the application of proceeds therefrom as described in the Preliminary Offering Memorandum as supplemented by the Pricing Term Sheet and in the Offering Memorandum, will not be, an “investment company” within the meaning of said term as used in the Investment Company Act of 1940, as amended.
13.    In a case properly argued and presented, a Texas court or a United States federal court sitting in Texas and applying Texas conflict of law principles as set out in Chapter 271 of the Texas Business and Commerce Code, would give effect to the provisions of the Securities and the provisions of the Indenture that purport to require that the rights and obligations of the parties thereto are to be governed by and construed in accordance with the laws of the State of New York.
In addition, we have participated in conferences with officers and other representatives of the Obligors, the independent registered public accounting firm and the reserve engineer for the Obligors, your counsel and your representatives at which the contents of the Time of Sale Information and the Offering Memorandum and related matters were discussed and, although we have not independently verified and are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained in the Time of Sale Information and the Offering Memorandum (except as and to the extent set forth in paragraphs 6 and 7 above), on the basis of the foregoing (relying as to factual matters to the extent we deem reasonable upon statements of fact made to us by representatives of the Obligors), no facts have come to our attention that have led us to believe that (i) the Time of Sale Information, as of 3:30 p.m. (Eastern Standard Time) on April 30, 2018 contained an untrue statement of a material fact or omitted to state any 

Exhibit A

material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (ii) the Offering Memorandum, as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, it being understood that we express no statement or belief with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon (and any other financial or accounting data derived therefrom) and (ii) oil and natural gas reserve estimates, in each case included in, or excluded from, the Offering Memorandum or the Time of Sale Information.
