 EMPLOYMENT AGREEMENT 
 This AMENDED AND RESTATED EMPLOYMENT AGREEMENT is effective as of December 2, 2008 by and between Randall Dean
(“Executive”) and Regency GP LLC (the “Managing General Partner”), the managing general partner of the general partner of Regency Energy Partners LP (the “Partnership”).

 WHEREAS, ADJHR, LLC (the “Company”) is an indirect wholly-owned subsidiary of the Partnership; and

 WHEREAS, the Managing General Partner employs Executive to serve as its employee and to serve as the President and Chief Executive
Officer of the Company; 
 WHEREAS, the Managing General Partner and Executive entered into an Employment Agreement dated effective
January 15, 2008 (the “Agreement”); and 
 WHEREAS, the Managing General Partner and Executive have
agreed to make certain modifications to the Agreement to comply with the provisions of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”). 
 NOW, THEREFORE, in consideration of the premises and the mutual covenants set forth below, to avoid adverse tax consequences under section 409A of
the Code and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows: 
 1. Employment. The Managing General Partner hereby agrees to employ Executive to serve as its employee and to serve as the President and Chief Executive Officer of the Company, and Executive hereby
accepts such employment, on the terms and conditions hereinafter set forth. 
 2. Term. The period of employment of Executive
by the Managing General Partner under this Agreement (the “Employment Period”) shall commence on January 15, 2008 (the “Commencement Date”) and shall continue through the third anniversary
thereof. 
 3. Position and Duties. During the Employment Period, Executive shall serve as the President and Chief Executive
Officer of the Company, and shall report to the Chief Executive Officer (or, if there is no Chief Executive Officer, the highest-level executive officer) of the Managing General Partner. Executive shall have those powers and duties with respect to
the Company normally associated with the position of President and Chief Executive Officer, and such other powers and duties as may be assigned to him by the Board of Directors of the Managing General Partner (hereinafter referred to as
“Board”); provided that, the Board shall assign him only such other powers and duties as are of a type, nature and dignity consistent with Executive’s position, and do not violate any applicable laws or
regulations. Subject to the remaining provisions hereof, Executive shall devote his full working time, attention and energies to the performance of his duties for the Managing General Partner. Executive shall retain the ability, without violating
the terms of employment with the Company or the Partnership’s 

 
conflict of interest policies, to (i) have an indirect economic interest in CDM MAX, LLC, a Texas limited liability company (“CDM
MAX”), (ii) have board-level involvement with the operations and affairs of CDM MAX, provided that such involvement does not significantly interfere with Executive’s duties to the Company, and (iii) receive
payments related to CDM MAX, both in respect of the indirect ownership position and consulting fees disclosed to the Managing General Partner; provided, however, that Executive may not cause CDM MAX to solicit customers of the
Partnership or any of its Subsidiaries in areas in which CDM MAX may become competitive with the Partnership or any of its Subsidiaries. Executive may also manage personal investments and engage in civic or charitable activities so long as the same
do not interfere with the performance of Executive’s responsibilities as an employee of the Managing General Partner in accordance with this Agreement. If, from time to time, the Company or an Affiliate of the Company desires that the Executive
render services to any such Affiliate outside the scope of the services described above, then (i) the Company shall first obtain authorization from the Chief Executive Officer (or, if there is no Chief Executive Officer, the highest-level
executive officer) of the Managing General Partner and (ii) any additional compensation to Executive for providing those services must be reasonably acceptable to Executive. 
 4. Place of Performance. The place of employment of Executive shall be at the Company’s principal executive offices in Houston, Texas,
or at such other offices as the Board may designate; provided, that, Executive shall not be required to relocate outside of the Greater Houston Metropolitan Area. Executive acknowledges that he may be required to travel on Company
business during the Employment Period. 
 5. Compensation and Related Matters. 
 (a) Base Salary. During the Employment Period, the Managing General Partner shall pay Executive a base salary at the rate of not less than $316,900
per year (“Base Salary”). Executive’s Base Salary shall be paid in accordance with the Managing General Partner’s customary payroll practices. The Compensation Committee of the Board shall annually review
Executive’s Base Salary for increase (but not decrease), consistent with the compensation practices and guidelines of the Managing General Partner. If Executive’s Base Salary is increased by the Managing General Partner, such increased
Base Salary shall then constitute the Base Salary for all purposes of this Agreement. 
 (b) Bonuses. During each full or partial
fiscal year of the Managing General Partner that occurs during the Employment Period, Executive shall be eligible for an annual performance bonus (the “Bonus”), to be awarded and determined at the sole discretion of the Board
or its Compensation Committee, of up to 100% of Executive’s then current Base Salary. The Bonus, if any, may be payable in cash, equity, or some combination thereof, at the discretion of the Board or such Compensation Committee. Any Bonus
earned during a fiscal year shall be paid at such time as the Managing General Partner customarily pays annual bonuses; provided, that, Executive is still employed as of such date, but in no event later than the 90th day of the year
following the fiscal year in which the Bonus is earned. 
 (c) Expenses. During the Employment Period, the Managing General Partner
shall promptly reimburse Executive for all reasonable business expenses upon the presentation of reasonably itemized statements of such expenses in accordance with the Managing General 

  

 2 

 
Partner’s generally applied policies and procedures now in force which provide an objectively determinable nondiscretionary definition of the expenses
eligible for reimbursement, or as such policies and procedures may be modified with respect to all executive officers of the Managing General Partner. Notwithstanding any provision of this Agreement to the contrary, the amount of expenses for which
Executive is eligible to receive reimbursement during any calendar year shall not affect the amount of expenses for which Executive is eligible to receive reimbursement during any other calendar year within the Employment Period. In addition, any
reimbursement of expenses provided for in this Agreement shall be made on or before the last day of the calendar year following the calendar year in which the expense was incurred. Executive is not permitted to receive a payment or other benefit in
lieu of reimbursement under Section 5(c). 
 (d) Vacation. During the Employment Period, Executive shall be entitled to the
maximum amount of paid time off (including vacation, sick days and personal time) permitted to employees of the Managing General Partner in accordance with the Managing General Partner’s generally applied policy as it may be established from
time to time (assuming more than ten years’ credited service by Executive. In addition to vacation, Executive shall be entitled to the number of national holidays per year that other executive officers of the Managing General Partner with
similar tenure are entitled under the Managing General Partner’s policies. 
 (e) Welfare, Pension and Incentive Benefit Plans and
Perquisites. During the Employment Period, Executive shall be entitled to participate in such employee benefit plans offered by the Managing General Partner, or that it may adopt from time to time, for its executives, in accordance with the
eligibility requirements for participation therein and the other terms and conditions thereof. 
 (f) Equity Awards. During each
fiscal year of the Company that occurs during the Employment Period, Executive shall be eligible to receive such equity awards (which may include Class C Common Units of Regency GP Acquirer LP) as the Board, or its Compensation Committee, may, in
its sole discretion, choose to award to him. 
 (g) Indemnification and Insurance. Executive shall be entitled to insured status under
the Managing General Partner’s Directors & Officers Liability Insurance to the same extent that its other executive officers are insureds. In addition, at or about the time of the execution of this Agreement, Executive and the Managing
General Partner shall enter into an indemnification agreement in substantially the form entered into and in effect with the Managing General Partners’ executive officers. 
 6. Termination Procedure.

 (b) Date of Termination. “Date of
Termination” shall mean (i) if Executive’s employment is terminated by his death, the date of his death, or (ii) if Executive’s employment is terminated pursuant to notice, the date the Notice of Termination is provided to

made, rather than to the Executive, into a bonus pool arrangement for the benefit of the Company’s employees, to be paid to them, as determined by the Compensation Committee of the Board, over and above the compensation they would otherwise
receive, under a written arrangement in which the Executive can be reasonably assured of such payment into such pool for the benefit of such employees, which shall be implemented within 90 days following the Date of Termination or, if not so timely
implemented, then such lump-sum payment shall be paid into a pool under Executive’s control who shall implement such pool for the benefit of such employees; 

  

	 	•	 	 payment of the Bonus for the fiscal year of termination based upon the maximum target Bonus level for such year, prorated on a per day basis from the first date of
such fiscal year through the Date of Termination, based on a calendar year of 365 or 366 days, as the case may be, to be paid immediately following the end of the fiscal year for which such Bonus relates, but in no event later than 74 days
thereafter; 

  

	 	•	 	 continuation of group health coverage, at the Managing General Partner’s expense, for the Executive and his spouse and dependents for a period of 36 months

	 	•	 	 notwithstanding anything to the contrary in any option or restricted unit agreement, accelerated vesting to the Date of Termination of all outstanding options and
restricted units as well as an extension of the period during which an award may be exercised to one year after the Date of Termination. 

  

 4

	 	•	 	 Executive’s material breach of the material terms of this Agreement. 

 (f) Definition of Good Reason For Termination. Executive shall have “Good Reason” for termination of the employment relationship with
the Managing General Partner upon any of the following to occur:

	 	•	 	 Any (1) changes (subject to the penultimate sentence of this bullet point paragraph) in the Company’s key executive personnel (vice president and above),
or material adverse change in their terms of employment, including salary or medical benefits, (2) material change in the business method by which the Company performs contract compression services, (3) cessation of the Company’s
quarterly bonus program for employees below the executive management team, or any change in such program (other than the amount thereof) that is materially adverse to such employees, or (4) relocation of the Company’s corporate office;
provided, however, that the items described in this bullet-point paragraph (“Interference Items”) shall no longer apply if, for any budget year (currently the calendar year), beginning with the year ending
December 31, 2008, the Company’s actual revenue is more than 10% less than the budgeted revenue established at the beginning of that year, as then approved by the Board. It shall not constitute “Good Reason” under clause
(1) if a change in personnel occurs as the result of the death or disability or voluntary resignation of any such personnel, provided that Good Reason shall exist if the replacement of any such personnel is not designated by or reasonably
acceptable to the Executive. It shall not constitute “Good Reason” under any such clause if the change or relocation is initiated or approved in writing by the Executive; 

 provided that, with respect to any of the above conditions, (i) Executive has provided the Managing General Partner written notice of the existence of such
condition, which notice must be given within 90 days of the initial existence of such condition, and (ii) the Managing General Partner has 30 days after the giving of such notice to remedy such condition.

jurisdiction to have breached the foregoing non-solicitation obligation, the Restricted Period shall be extended for the term of the breach as found by such court. For the absence of doubt, Executive’s activities as specifically contemplated
by, and in accordance with, Section 3 as it relates to CDM MAX, shall not constitute a violation of this paragraph (d) or paragraph (e) below. 
  

 8 

 (e) Non-Solicitation of Clients, Customers and Contact Sources. In consideration of the benefits
provided for in this Agreement, Executive covenants and agrees that during the Restricted Period, he will not, for himself or any other Person, directly or indirectly: (i) solicit or accept any business of the type engaged in by the Company,
the Partnership or any of its other Subsidiaries, from any person or entity who, at the time of, or at the time during the 12 months preceding, the Date of Termination, was an existing customer, client or contact source of the Partnership or any of
its Subsidiaries; or (ii) cause any of such clients, customers or contact sources of the Partnership or any of its Subsidiaries to cancel or terminate any business relationship with the Partnership or any of its Subsidiaries involving services
or activities that were directly or indirectly the responsibility of Executive during his employment; except in any such case on behalf of the Company, the Partnership or another Subsidiary in carrying out the Executive’s duties hereunder.

 (f) Enforcement. If Executive commits a breach, or overtly threatens to commit a breach, of any of the provisions of this
Section 7, the Managing General Partner and the Company shall have the right and remedy to have the provisions specifically enforced by any court having jurisdiction, it being acknowledged and agreed by Executive that the services being
rendered hereunder to the Managing General Partner and the Company are of a special, unique and extraordinary character and that any such breach or threatened breach may cause irreparable injury to the Partnership and its Subsidiaries and that money
damages may not provide an adequate remedy to the Managing General Partner or the Company. Such right and remedy shall be in addition to, and not in lieu of, any other rights and remedies available to the Managing General Partner or the Company at
law or in equity in connection with any such breach. Accordingly, Executive consents to the issuance of an injunction, whether preliminary or permanent, consistent with the terms of this Agreement. 
 (g) Blue Pencil. If, at any time, the provisions of this Section 7 shall be determined to be invalid or unenforceable under any applicable
law, by reason of being vague or unreasonable as to area, duration or scope of activity, this Agreement shall be considered divisible and shall become and be immediately amended to only such area, duration and scope of activity as shall be
determined to be reasonable and enforceable by the court or other body having jurisdiction over the matter, and Executive and the Managing General Partner agree that this Agreement as so amended shall be valid and binding as though any invalid or
unenforceable provision had not been included herein. 
 (h) EXECUTIVE ACKNOWLEDGES THAT HE HAS CAREFULLY READ THIS SECTION 7 AND HAS
HAD THE OPPORTUNITY TO REVIEW ITS PROVISIONS WITH ANY ADVISORS AS HE CONSIDERED NECESSARY AND THAT EXECUTIVE UNDERSTANDS THIS AGREEMENT’S CONTENTS AND SIGNIFIES SUCH UNDERSTANDING AND AGREEMENT BY SIGNING BELOW. 
 8. Resolution of Differences Over Breaches of Agreement. The parties shall use their good faith efforts to resolve any controversy or claim
arising out of, or relating to, this Agreement or the breach thereof, first in accordance with the Managing General Partner’s 

  

 9 

 
internal review procedures, including prior to any determination of Cause or Good Reason, except that this requirement shall not apply to any claim or
dispute under or relating to Section 7 of this Agreement. 
 9. Successors; Binding Agreement. The rights and benefits of
Executive hereunder shall not be assignable, whether by voluntary or involuntary assignment or transfer by Executive, except that payments and benefits payable to Executive hereunder shall inure to the benefit of his estate, spouse and
beneficiaries, as applicable. This Agreement shall be binding upon, and inure to the benefit of, the successors and assigns of the Managing General Partner, and the estate, heirs, executors, administrators, beneficiaries and permitted assigns of the
Executive, and shall be assignable in whole (but not in part) by the Managing General Partner to any entity acquiring, directly or indirectly, the Company or substantially all of the assets of the Company, whether by merger, consolidation, sale of
assets or similar transactions, without, however, relieving the Managing General Partner of its obligations hereunder (including those after the date of assignment). 
 10. Notice. For the purposes of this Agreement, notices, demands and all other communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given on the date
personally delivered or three business days following the date deposited in the United States mail (certified or registered, return receipt requested, postage prepaid), addressed, in case of Executive, to the last address on file with the Company
and, if to the Managing General Partner, to its executive offices or to such other address as any party may have furnished to the other in writing in accordance herewith, except that notices of change of address shall be effective only upon receipt.

 11. Delay in Payment. Notwithstanding the timing requirements set forth above, in the event that the Executive is a
“specified employee” at the time of his “separation from service” according to the meaning of such terms in Treasury Regulation § 1.409A-1(i), any payment due to Executive pursuant to this Agreement that is required to
be delayed for a six month period in accordance with the restrictions of section 409A of the Code and the regulations promulgated thereto, shall be paid instead to the Executive on the first day of the seventh month following the Executive’s
Date of Termination. 
 12. Governing Law; Venue; Severability. This Agreement is governed by, and is to be construed and
enforced in accordance with, the laws of the State of Texas without regard to principles of conflicts of laws. Each party (i) consents to submit itself and himself to the personal jurisdiction of any federal or state court located in Houston,
Texas if any dispute arises out of this Agreement or any of the transactions contemplated herein, (ii) agrees that it or he will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court
and (iii) agrees that it or he will not bring any action relating to this Agreement or any of the transactions contemplated herein in any court other than any federal or state court sitting in Houston, Texas. Except as otherwise provided
herein, if any portion of this Agreement is at any time deemed to be in conflict with any applicable statute, rule, regulation or ordinance, such portion shall be deemed to be modified or altered to conform thereto or, if that is not possible, to be
omitted from this Agreement, and the invalidity of any such portion shall not affect the force, effect and validity of the remaining portion hereof. 
  

 10 

 13. Amendment. No provisions of this Agreement may be amended, modified, or waived unless
such amendment or modification is agreed to in writing signed by Executive and by a duly authorized officer of the Managing General Partner, and such waiver is set forth in writing and signed by the party to be charged. No waiver by either party
hereto at any time of any breach by the other party hereto of any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or
subsequent time. 
 14. Survival. The respective obligations of, and benefits afforded to, Executive and Managing General
Partner and the Company as provided in Section 7 of this Agreement shall survive the termination of this Agreement, together with any other provisions hereof which by their nature contemplate survival. 
 15. Mutual Non-Disparagement Obligation. Executive agrees that he shall not, during the employment relationship and for a period of three
years after the Date of Termination, make any disparaging remarks concerning the Company, the Managing General Partner, the Partnership or any of its Subsidiaries. The Managing General Partner agrees that it shall not, and it shall not cause or
permit the Company, the Partnership or any of the Partnership’s other Subsidiaries to, during the employment relationship and for a period of three years after the Date of Termination, make any disparaging remarks concerning the Executive.

 16. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an
original but all of which together shall constitute one and the same instrument. 
 17. Entire Agreement. This Agreement sets
forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, in
respect of such subject matter. Any prior agreement of the parties hereto in respect of the subject matter contained herein is hereby terminated and canceled as of the date hereof. 
 18. Section Headings. The section headings in this Agreement are for convenience of reference only, and they form no part of this Agreement
and shall not affect its interpretation. 
 19. Withholding. All payments hereunder shall be subject to any required
withholding of Federal, state and local taxes pursuant to any applicable law or regulation. 
 20. Representation. Executive
represents and warrants to the Managing General Partner, and Executive acknowledges that the Managing General Partner has relied on such representations and warranties in employing Executive to serve as the President and Chief Executive Officer of
the Company, that neither Executive’s duties as an employee of the Managing General Partner nor his performance of this Agreement will breach any other agreement to which Executive is a party, including, without limitation, any agreement
limiting the use or disclosure of any information acquired by Executive prior to his employment by the Managing General Partner. In addition, Executive represents and warrants and acknowledges that the Managing General Partner has relied on such
representations and warranties in employing Executive, and that he has not entered into, and will not enter into, any agreement, either oral or written, in conflict herewith.

Lease”), dated as of February 26, 2009, is between Caterpillar Financial Services Corporation (“Lessor”), a Delaware corporation whose address is 2120 West End Avenue, Nashville, Tennessee 37203, and
CDM Resource Management LLC (“Lessee”), a Texas limited liability company with a principal address of 20405 Tomball Pkwy, Suite 310, Houston, TX, 77070. 
 In consideration of the mutual covenants and agreements hereinafter set forth, the parties hereto agree as follows: 
 Section 1. Definitions. The capitalized terms used in this Master Lease and not otherwise defined herein shall have the respective meanings specified in Appendix A hereto, unless the
context hereof shall otherwise require. 
 Section 2. Master Lease. Lessor hereby leases to Lessee and Lessee hereby leases
from Lessor the Equipment and other property described on each Lease Schedule executed from time to time by Lessor and Lessee in a form acceptable to Lessor (each a “Schedule”). Each Schedule shall expressly incorporate the
terms of this Master Lease and shall constitute a separate lease along with any other writing expressly incorporated into the Master Lease or the Schedule. The terms “Lease” or “this Lease” as used
herein shall refer to each and every Schedule that incorporates this Master Lease and any other writing expressly incorporated into the Master Lease or such Schedule. In the event of any conflict between the Master Lease and any Schedule, the terms
of the Schedule shall control. Upon Lessee’s satisfaction of all conditions precedent to effectiveness of this Master Lease, including those set forth in Section 9 with respect to the execution of Schedules: (a) this Master Lease
shall constitute a legal commitment by Lessor to lease equipment in accordance with the terms herein and in each such Schedule and (b) Lessor shall be obligated to enter into Schedules and purchase and lease the equipment or other property
pursuant thereto. After executing a Schedule, Lessor shall have no obligation to purchase or finance any Equipment until the satisfaction of all conditions precedent to Lessor’s purchase of Equipment pursuant to the terms of the Master Lease
and said Schedule. 
 Section 3. Title; UCC 2A Finance Lease; Waivers. 
 (a) Lessee and Lessor intend that: (i) each Lease constitutes a true “lease” that is a “finance lease” as such terms are defined
in Article 2A of the UCC and does not create a “security interest” as defined in the UCC; (ii) Lessor is and shall remain the owner of the Equipment (unless sold by Lessor pursuant to any Lease Document); (iii) Lessee shall not
acquire any right, title, equity or interest in or to such Equipment other than the right to possess and use the Equipment in accordance with Lessee’s leasehold interest under the Lease. If, notwithstanding the intention of the parties and the
economic realities of this Lease, this Lease is deemed to create a security interest, Lessee shall be deemed to have granted to Lessor as security for Lessee’s obligations hereunder, a first priority security interest in the Equipment and all
proceeds thereof. Until Lessee’s obligations under each Schedule are satisfied in full, if requested by Lessor or if required by Applicable Law, Lessee shall at Lessee’s sole cost and expense permanently affix and maintain on any or all
Equipment or as many items as required, as determined by Lessor or as required by Applicable Law, a sign, legend, plate, plaque, tag or other identifying label in a prominent place that discloses Lessor’s ownership or that such Equipment is
leased from Lessor under such Schedule. 
 (b) Lessee further acknowledges that at least one of the following is true: (i) Lessee has
selected the Supplier (as defined in Article 2A of the UCC), has directed Lessor to purchase the Equipment from the Supplier and has been informed by Lessor in writing (and is so hereby informed) that (A) Lessee is entitled under Article 2A of
the UCC to certain rights under the Supply Contract (as defined in Article 2A of the UCC), and (B) Lessee may contact the Supplier to receive an accurate and complete 

  

 1 

 
statement from the Supplier of any such rights and any disclaimers and limitations of them or of remedies; or (ii) Lessee has received, reviewed and
approved a copy of the Supply Contract covering the Equipment purchased from the Supplier thereof for lease to Lessee. To the fullest extent permitted by Applicable Law, Lessee hereby waives any and all rights and remedies conferred upon lessees by
Sections 2A-508 through 2A-522 of the UCC as currently in force on the date hereof or otherwise conferred upon Lessee by the UCC. Lessee further waives, to the extent permitted by Applicable Law notice of sale or other disposition of the Equipment.

Lessee shall pay to Lessor, in addition to such Rent or other payment, late fees on such amounts from the date due until payment is received by Lessor equal to the lesser of (a) five percent (5%) per annum on such amount (it being
understood and agreed by the parties that such percentage shall be applied based on a calendar year of 365 days, with the interest on any given day being 1/365 of the total interest for the calendar year); and (b) the highest charge allowed by
Applicable Law. The Lessee shall pay the reasonable expenses of Lessor (including fees and out-of-pocket expenses of Lessor’s attorneys and Lessor’s engineer) incurred at the request of Lessee, or in the performance of its duties under any

 4.3 Termination. Each Lease shall terminate upon the earlier of (a) the end of the Term; or (b) the date upon which Lessor
or Lessee terminates the Lease pursuant to any terms hereunder. No termination (whether by default or the passage of time) shall affect or impair the rights, powers or privileges of Lessor or the liabilities of Lessee relating to (i) any
transaction or event occurring prior to the effective date of such termination or (ii) any of the undertakings, agreements, covenants, indemnifications, representations or warranties of Lessee contained in the Lease Documents. All such
undertakings, agreements, covenants, indemnities, representations, and warranties of Lessee shall survive such termination and Lessor shall retain all of its rights and remedies under the Lease Documents.

Lessee without notice or demand and without any abatement, reduction, diminution, setoff, defense, counterclaim or recoupment whatsoever, including:

impossibility. Lessee may not cancel this Lease, and unless expressly provided otherwise herein or in the applicable Schedule, Lessee may not make any full or partial prepayments with respect to sums due hereunder. 
 Section 5. Lessee Options 
 5.1
Early Buyout Option. Lessor hereby grants to Lessee the option, exercisable only as provided herein, to purchase all but not less than all Equipment leased pursuant to each Schedule prior to the expiration of the Term for such
Schedule, subject to the following: (a) so long as no Event of Default, or event which with notice, lapse of time or both would become an Event of Default shall have occurred, Lessee shall have the right at its option to purchase all, but not
less than all, Equipment leased pursuant to each Schedule (the “EBO Equipment”) on the Fifth (5th) and Seventh (7th) anniversaries of the Base Term Commencement Date (each an “EBO Date”);
provided, however, that Lessee shall have given at least ninety (90) days but not more than one hundred fifty (150) days prior written notice (which notice shall be irrevocable without Lessor’s written consent) to Lessor; (b) on
the EBO Date: (i) Lessee shall pay to Lessor an amount equal to: (A) Seventy-Five Percent (75%) of the Lessor’s Cost set forth on the Schedule in the event the EBO Date is the Fifth anniversary of the Base Term Commencement Date
or Fifty-Six Percent (56%) of the Lessor’s Cost set forth on the Schedule in the event the EBO Date is the Seventh anniversary of the Base Term Commencement Date; plus (B) all other amounts due under such Schedule with respect to the
EBO Equipment, including the Rent payment due on the EBO Date and applicable Taxes and other amounts due or payable with respect to such sale and (ii) Lessor shall sell such Equipment for cash to Lessee, AS IS, WHERE IS, without recourse or
warranty (except that Lessor has whatever title (if any) to the Equipment that was conveyed to it by the Vendor free of any security interest arising solely by reason of a claim against Lessor that Lessee is not responsible to remove pursuant to
this Lease). Provided that Lessee has complied with all obligations contained herein, such Schedule shall be deemed terminated on the EBO Date and Lessee shall have no further obligations to pay Rent thereunder. Notwithstanding anything to the
contrary herein, Lessee hereby agrees that: (1) Lessee’s exercise of the Early Buyout Option under this Section 5.1 with respect to Equipment leased pursuant to one Schedule shall be automatically deemed to be an election of its Early
Buyout Option to purchase all Equipment leased under all other Schedules to this Master Lease at the same EBO Date (Fifth or Seventh anniversary, as applicable) for such other Schedules in accordance with the terms thereof (which notice shall be
irrevocable without Lessor’s written consent); and (2) if Lessee elects not to exercise its Early Buyout Option to purchase Equipment pursuant to this Section 5.1 on any EBO date with respect to any Schedule, it shall be deemed to
have waived its rights to exercise its Early Buyout Option to purchase all Equipment leased under all other Schedules to this Master Lease on the same EBO Date. 
 5.2 Purchase Option. Provided that no Event of Default, and no event which with lapse of time or giving of notice or both would become an Event of Default, has occurred, Lessee may elect, by

  

 3 

 
giving Lessor not less than one hundred eighty (180) days but not more than two hundred forty (240) days prior written notice (which notice shall
be irrevocable without Lessor’s written consent), to purchase all, but not less than all, Equipment (the “Purchased Equipment”) as of the last day of the Base Term. In the event Lessee elects to purchase the Purchased
Equipment from Lessor, it shall pay to Lessor on the date of expiration of the Base Term an amount equal to Twenty Four and Fifteen One-Hundredths Percent (24.15%) of the Lessor’s Cost set forth on the Schedule together with all other
amounts due under such Schedule with respect to the Purchased Equipment plus applicable Taxes and other amounts due or payable with respect to such sale. All Purchased Equipment shall be sold to Lessee on an AS IS, WHERE IS BASIS,
without recourse or warranty (except that Lessor has whatever title (if any) to the Equipment that was conveyed to it by the Vendor free of any security interest arising solely by reason of a claim against Lessor that Lessee is not responsible to
remove pursuant to this Lease). Lessor and Lessee agree that the percentage multiplied by Lessor’s Cost in this Section 5.2 is a reasonable estimate of the fair market value of the Equipment at the end of the Base Term. Notwithstanding
anything to the contrary herein, Lessee hereby agrees that: (a) Lessee’s exercise of its Purchase Option with respect to Equipment leased pursuant to one Schedule shall be automatically deemed to be an election of its option to purchase
all Equipment leased under all other Schedules to this Master Lease at the end of the Base Term of such Schedules in accordance with the terms thereof (which notice shall be irrevocable without Lessor’s written consent); and (b) if Lessee
elects not to exercise its Purchase Option right with respect to any Schedule, it shall be deemed to have waived its rights to exercise its option to purchase all Equipment leased under all other Schedules to this Master Lease. 
 5.3 Renewal Option. 
 (a)
Provided that no Event of Default, and no event which with lapse of time or giving of notice or both would become an Event of Default has occurred, Lessee shall have the option, exercisable upon not less than one hundred eighty (180) days but
not more than two hundred forty (240) days prior written notice (which notice shall be irrevocable without Lessor’s written consent), to extend the Base Term for an additional period of Sixty (60) months (the “Renewal
Term”). During the Renewal Term, all of the terms and provisions of this Lease, shall continue to apply provided, however that quarterly Rent shall be adjusted at the beginning of the Renewal Term to equal the Fair Market Rental Value
at such time. As used herein, the term “Fair Market Rental Value” means the rental value of the Equipment as determined on the basis of, and will be equal in amount to, the value which one would obtain in an arm’s-length
transaction between an informed and willing lessee-user (other than a lessee currently in possession and a used equipment dealer) and an informed and willing lessor under no compulsion to lease and, in such determination it will be assumed that the
Equipment is in the condition required to be maintained and returned under this Lease and is value on an installed basis and the costs of removal from current location shall not be a deduction from such valuation. For purposes of this Master Lease,
the Fair Market Rental Value for the Equipment shall be determined by mutual agreement of Lessor and Lessee. If such mutual agreement cannot be reached, then it shall be determined by the Appraisal Process. If Fair Market Rental Value is not
determined by the end of the Base Term, the Base Term shall, at Lessor’s election, be extended at the current Rental amount until Fair Market Rental Value is calculated as provided herein. At the end of the Renewal Term, Lessee shall comply
with the provisions of this Lease regarding return or purchase of the Equipment. 
 (b) Notwithstanding anything to the contrary herein,
Lessee hereby agrees that: (i) Lessee’s exercise of its Renewal Option with respect to Equipment leased pursuant to one Schedule shall be automatically deemed to be an election of its Renewal Option with respect to all Equipment leased
under all other Schedules to this Master Lease at the end of the Base Term of such Schedules in accordance with the terms thereof (which notice shall be irrevocable without Lessor’s written consent); and (ii) if Lessee elects not to
exercise its Renewal Option with respect to any Schedule, it shall be deemed to have waived its rights to exercise its Renewal Option with respect to all Equipment leased under all other Schedules to this Master Lease.

 5.4 Return of Equipment 
 (a) Unless Lessee purchases the Equipment, if allowed in accordance with the terms hereof: (i) Lessee shall be obligated to return the Equipment to
Lessor at the end of the Term or as required by Lessor upon the occurrence of an Event of Default under Section 15.2; and (ii) Lessee shall at its sole expense demobilize, load, and transport the Equipment to any location in the
Continental United States designated by Lessor such that possession is delivered to Lessor on the last day of the Term or immediately upon the occurrence of an Event of Default; provided, however, that if the location specified by Lessor is outside
of the Return Radius from the Property where the Equipment was located pursuant to the applicable Permitted Use Agreement (the “Site Location”), Lessor shall pay that portion of the actual transportation costs which exceeds
the transportation costs which would have been incurred by Lessee in transporting the Equipment a distance equal to the maximum Return Radius. As used herein the “Return Radius” shall mean the number of miles from the
Vendor’s location from which the Equipment was originally delivered to the Site Location. 
 (b) Any and all components of the Equipment
returned to Lessor shall be in the same physical and mechanical condition as originally delivered (except for Reasonable Wear and Tear) and in Average Saleable Condition. For purposes of this Lease “Reasonable Wear and Tear”
shall mean: (i) the results of normal use of the Equipment as originally intended assuming use and maintenance in accordance with the Vendor’s recommendations and the complete absence of any casualty, misuse, abuse, abandonment, improper
care, accident, negligence or similar occurrence with respect to the Equipment, whether or not the Equipment is in use at the time of said occurrence; and (ii) use that does not, in any way, impair the function of the Equipment or prevent the
Equipment from promptly being placed into use. For purposes of this Lease “Average Saleable Condition” shall mean such condition that: (A) all components have at least a fifty (50%) remaining life until the next
scheduled overhaul; (B) the Equipment has been properly operated and maintained in accordance with prudent industry practice; (C) the Equipment operates at its rated horsepower, temperature, pressure, fuel consumption, capacity, and
efficiency and energy requirement, Reasonable Wear and Tear excepted; and (D) in accordance with any additional return requirements set forth in the applicable Schedule. 
 (c) If Lessee is required to return the Equipment in accordance with the terms hereof, Lessee shall provide Lessor, at Lessee’s sole cost and
expense at least ninety (90) days prior to the end of the Term (or immediately if the Equipment is returned due to an Event of Default), with a true, accurate and complete set of all material documentation for the Equipment setting forth a
detailed description of its components and its operating and maintenance history, all in form reasonably satisfactory to Lessor. Lessee shall also, at its sole expense (but not to exceed $250.00 per compressor package) at least sixty (60) days
prior to the end of the Base Term (or the Renewal Term if Lessee has exercised its Renewal Option) have an authorized manufacturers’ representative, or other person approved in advance in writing by Lessor, review each compressor package’s
operating and maintenance history and, if requested by Lessor, conduct various field tests to confirm that natural gas compressor packages constituting the Equipment is in Average Saleable Condition. Lessor shall also have the right to make such
inspections and tests as it deems necessary or desirable to determine if the Equipment is in conformance with the requirements listed in this Section 5.4. 
 (d) Lessor shall indicate its approval or rejection of the condition of the returned Equipment by having its authorized representative sign and deliver to Lessee the Form Acceptance upon Return. If the Equipment does
not meet the physical and/or mechanical requirements set forth above, then Lessee is to make the necessary corrections specified on the Form Acceptance upon Return within thirty (30) days (during which time Rent shall accrue and become due).
Once such corrections are satisfactorily made by Lessee as evidenced solely by Lessor’s execution of the acceptance portion of the Form Acceptance upon Return, the subject Equipment will be deemed accepted by Lessor for purposes of in this
Section 5.4. If the Equipment is not in the condition required, Lessee shall pay to Lessor, on demand, all costs, and 

  

 5 

 
expenses incurred by Lessor to bring the Equipment into the required condition. Lessee expressly agrees that, in the event Lessee does not elect to purchase
the Equipment in accordance with the terms hereof, Lessor has the right to arrange for the sale or other disposition prior to the Equipment’s return (provided that such sale shall not close until the end of the applicable Term) and Lessee
agrees to facilitate any such sale or disposition of the Equipment and that Lessor, its agents or employees, shall have the right to enter the Property for the purpose of showcasing the Equipment for sale or other disposition. 
 (e) Any entrance on the Property for inspection, showcasing or other purposes under this Section 5.4 shall be conducted in accordance with the
provisions of Section 7.3(b) hereof.

 (b) Lessee agrees that: (i) each Purchase Agreement shall identify Lessor as the Person with the right to purchase the Equipment pursuant to the

payment thereunder for the benefit of Lessee (other than under the terms and conditions set forth in this Lease). Each Purchase Agreement shall be acceptable to Lessor and Lessee will have no right to bind Lessor to any change in the Purchase
Agreement, any delivery schedule, or any other agreement whatsoever and Lessee not shall not change any Purchase Agreement without Lessor’s prior written consent. So long as Lessee is not in default hereunder, Lessor hereby appoints and
constitutes Lessee as its agent and attorney-in-fact during the term of this Lease to assert and enforce from time to time, for the account of Lessor, at Lessee’s sole cost and expense, whatever claims and rights Lessor may have against any
Vendor for breach of warranty.

 7.2. Alterations to Equipment. Provided that no Event of Default exists under this Lease and no
event which with lapse of time or giving of notice or both would become an Event of Default, Lessee may at its sole cost and expense make any alterations, additions, repairs, modifications or attachments (“Improvements”) to
the Equipment or any other part of the Equipment provided that Lessee notifies 

  

 7 

 
Lessor in advance of such action in writing (except in those cases where Lessee must make emergency or other immediate Improvements to preserve or return the
Equipment to operational status or comply with Applicable Law, in which case advance notice shall not be required and Lessee shall notify Lessor as soon as is practicable after making such Improvements) and provided further that such Improvements,
in Lessor’s judgment: (a) do not reduce the value or general usefulness of any part of the Equipment; (b) do not impair the certification, performance, safety, quality, capability, use or character of any part of the Equipment, or

If no Event of Default has occurred and is continuing and such Improvements are readily removable without causing material damage to the Equipment, Lessee shall have the right to remove any Improvements at its own expense prior to the return of the
Equipment to Lessor, provided that removal will not impair its originally intended function or use. If any Improvements are not readily removable without causing material damage to the Equipment (or if removable but not removed by Lessee as when
returned to Lessor), such Improvement shall automatically and without payment by Lessor become the property of Lessor subject to all provisions of this Lease. 
 7.3 Inspection. 
 (a) Lessor and its agents shall have the right at Lessee’s sole expense
to inspect the Equipment, observe its use and inspect any information, written or otherwise, relating to it and to perform due diligence examinations and audit Lessee not to exceed four times in any calendar year; provided that Lessor is not
obligated to do so and provided, further, that no restrictions on how frequently Lessor may conduct such inspections shall be applicable if a default or Event of Default shall have occurred and then be continuing. Lessor assumes no responsibility
and waives no rights as a result of any inspection or observation or the lack thereof. 
 (b) So long as no default or Event of Default shall
have occurred and then be continuing: (i) Lessor shall provide Lessee with reasonable advance notice of such inspections; (ii) such inspections shall occur only at reasonable times during usual business hours; and (iii) Lessee shall
have the right to have its representatives present during any such inspections or other entry on the Property by Lessor, and Lessor shall not enter the Property without having a Lessee representative present. 
 7.4 Personal Property. The Equipment shall remain personal property regardless of its use or manner of attachment to the Property. The
Lessee recognizes that the Equipment and any improvements represented thereby are removable and separable from, and not essential to, the Property and recognizes the right of Lessor to remove any portion of the Equipment and each Permitted Use
Agreement shall contain similar statements from the applicable Permitted Users in form and substance satisfactory to Lessor.

the date any item or component of the Equipment is delivered until it is returned to Lessor. Lessee shall prepare and file, in a manner satisfactory to Lessor, any reports or returns which may be required with respect to the Equipment. For purposes
of this Section 12, “Lessor” shall include any affiliated group, within the meaning of Section 1504 of the Code, of which Lessor is a member for any year in which a consolidated or combined income tax return is filed for
the affiliated group. Lessee further agrees to pay all amounts owing by it under this Lease or the other Lease Documents free and clear of and without deduction for any present or future Taxes, and further agrees that: (a) if it is prevented by
operation of law from paying any Taxes, then the fees required to be paid under this Lease or the other Lease Documents shall be increased by the amount necessary to yield to Lessor the Rent or fees at the rates specified in this Lease or the other
Lease Documents after provision for the payment of all such Taxes and without taking into account any tax benefits accruing to Lessor from such payment (and shall, at the request of Lessor, execute and deliver to Lessor such further instruments as
may be necessary or desirable to effect the increase in the Rent or fees as provided for herein); (b) it 

  

 17 

 
shall hold Lessor harmless from and against any liabilities with respect to any Taxes (whether or not properly or legally asserted); and (c) it shall
provide Lessor with the original or a certified copy of evidence of the payment of any Taxes by it, as Lessor may reasonably request, or, if no Taxes are to be paid, to provide to Lessor, at Lessor’s request, a certificate from the appropriate
taxing authority or an opinion of counsel acceptable to Lessor stating that no Taxes are payable. If Lessor shall receive a refund of any Taxes paid by Lessee pursuant to this Section 12 by reason of the fact that such Taxes were not correctly
or legally asserted, Lessor shall within thirty (30) days after receipt of such refund pay to Lessee the amount of such refund, as determined solely by Lessor; provided, however, that in no event shall the amount paid by Lessor to Lessee
pursuant to this Section 12 exceed the amount of Taxes originally paid by Lessee. Notwithstanding anything to the contrary herein, Lessor shall not have any obligation under this Lease to claim or otherwise seek to obtain any refunds but shall
cooperate with Lessee with respect to any and all reasonable attempts by Lessee to obtain any such refunds. All of the foregoing obligations which relate to occurrences or events during the Term of this Lease are continuing and shall survive
expiration, termination, or cancellation hereof. 
 Section 13. Loss or Damage; Indemnification 
 13.1 Casualty Occurrence. Lessee shall bear the risk if a Casualty Occurrence or other damage occurs to the Equipment from the date of the
Master Lease until all Obligations have been satisfied. Lessee shall give Lessor prompt notice of a Casualty Occurrence or other damage to the Equipment which does not constitute Reasonable Wear and Tear. If, in Lessor’s opinion, any damage to
the Equipment is not a Casualty Occurrence, Lessee shall, at its expense, promptly restore the Equipment to the condition required herein. If the damage is a Casualty Occurrence, Lessee shall pay to Lessor on the first Rent payment due date
following the Casualty Occurrence (thirty (30) days after the Casualty Occurrence if there is no Rent payment due date remaining) all amounts then due under this Lease with respect to the item or component of the Equipment suffering said
Casualty Occurrence (the “Casualty Impaired Equipment”), plus a sum equal to the applicable Casualty Value of the Casualty Impaired Equipment, as applicable. Upon making this payment, the Term with respect to the Casualty
Impaired Equipment shall terminate and Lessee shall be entitled to possession of the Casualty Impaired Equipment and shall be responsible for its sale or other disposition. Lessee shall be entitled to any recovery from insurance or otherwise,
related to the Casualty Impaired Equipment to the extent it exceeds the amount of the Casualty Value paid by Lessee. 
 13.2 General
Indemnity. Lessee hereby agrees to defend, indemnify and hold Lessor (and at Lessor’s option, Lessor’s employees, agents, directors, partners, shareholders, officers, members and any assignee or secured party)(the
“Lessor Indemnified Parties”), harmless from and against (a) all claims, demands, suits and legal proceedings (whether civil, criminal, administrative, investigative or otherwise), including arbitration, mediation,
bankruptcy and appeal and including any claims, demands suits and legal proceedings (i) arising out of the actual or alleged manufacture, purchase, financing, ownership, delivery, rejection, non-delivery, possession, use, rental,
transportation, storage, operation, maintenance, repair, return or other disposition of the Equipment or any part of the Equipment, (ii) by any Governmental Authority or any third party under any Environmental Law, under any common law tort
claim theory applicable to Hazardous Materials or any Hazardous Materials remediation otherwise required to be performed or conducted under any applicable Environmental Law; (iii) patent, trademark or copyright infringement; (iv) related
to or arising out of or in connection with any Permitted Use Agreement, (v) related to any actual default by Lessee of this Lease or any other Lease Document; and (vi) related to any default under this Lease or any other Lease Document
reasonably alleged by Lessor (whether or not such occurrence, act of failure to act, constitutes an actual default) (collectively, “Actions”); and (b) any and all penalties, losses (including Environmental Losses),
liabilities (including the liability of Lessee or Lessor for negligence, tort and strict liability), damages, costs, court costs and any and all other expenses (including Attorneys’ Fees, judgments and amounts paid in settlement), related to,
arising out of or in any way connected with any Actions. Lessee shall, at Lessor’s option, appear and defend any such Action and 

  

 18 

 
pay the cost of the defense of any such action brought against Lessor, either alone or in conjunction with others, upon any such liability or claim. Lessee
shall satisfy, pay, and discharge any and all judgments and fines that may be recovered against Lessor in any such action. Notwithstanding the foregoing, Lessee does not have to indemnify any Lessor Indemnified Parties to the extent damages
otherwise covered under this Section XI are adjudged by a court of competent jurisdiction to have been the result of the gross negligence or willful misconduct of any of the Lessor Indemnified Parties so long as the Actions are not asserted on the
basis of (A) theories of vicarious liability, including agency, apparent agency or employment; (B) theories that any Lessor Indemnified Parties negligently entrusted the Equipment to Lessee, any Permitted User any other third party using
the Equipment by or through Lessee or such Permitted User; or (C) the failure of any Lessor Indemnified Parties to compel Lessee to comply with the provisions of this Lease. The foregoing Indemnities are continuing indemnities and shall survive
expiration, termination or cancellation 
 13.3 Tax Indemnity. 
 (a) Lessor and Lessee hereby agree that: (i) the Equipment constitutes depreciable personal property used in a trade or business; and
(ii) Lessor is entitled to such deductions, credits and other tax benefits as are or may be allowed under the Internal Revenue Code of 1986, as amended (the “Code”) or under any state or local income tax laws, to the
owner of depreciable personal property used in a trade or business. Except as otherwise provided herein and without limiting the foregoing, Lessor shall be entitled to all tax benefits generally available to owners and lessors of business equipment
including (A) the MACRS deductions for each item of Equipment allowable under Section 168 of the Code (together with corresponding deductions under applicable state law, the “MACRS Deductions”) computed on a basis
equal to Lessor’s Cost for such Equipment and the MACRS period assumed by Lessor in calculating Rent; (B) the deduction under Section 163 of the Code (the “Interest Deductions”) with respect to interest paid by
Lessor on any indebtedness incurred by Lessor in financing its purchase of the Equipment; and (C) Lessee shall prevent the Equipment from being used in any manner that would diminish its depreciable life. 
 (b) If all or any portion of Lessor’s share of MACRS Deductions, Interest Deductions or other tax benefits associated with the ownership of the
Equipment (the MACRS Deduction, Interest Deduction and other tax benefits being herein called the “Tax Benefits”) is reduced for any year or reporting period, disallowed, or denied, or if any Tax Benefit is recaptured, with
respect to any item of Equipment (a “Disallowance”), or if any modification, Improvement or use of any item shall result in the realization of income by Lessor for federal or state income tax purposes (an
“Inclusion”), the Rent for such Equipment shall be increased by an amount that, in the reasonable opinion of Lessor, will cause Lessor’s anticipated cash flow and after-tax return over the Term for such Equipment
to equal Lessor’s cash flow and such after-tax return that would have been obtained had such Disallowance or Inclusion had not occurred. After the occurrence of a Disallowance or Inclusion, Lessor shall provide Lessee written notice of such
Disallowance or Inclusion, which notice shall contain the amount of any increase in Rent resulting from the Disallowance or Inclusion. The Rent for such Equipment shall be increased by the amount stated in such written notice to Lessee as of the
date of such notice. If any Disallowance or Inclusion occurs after the expiration of this Lease, Lessee hereby agrees to and shall indemnify Lessor for the full amount of any such Disallowance or Inclusion upon demand of Lessor. At Lessor’s
election, Lessee shall pay to Lessor an amount that, after deduction of all taxes payable by reason of payment under this Section 13.3, compensates Lessor fully for such Disallowance or Inclusion. 
 (c) A Disallowance or Inclusion shall be deemed to occur upon the earliest of: (i) the happening of any event or condition (such as disposition or
change in use of any item of Equipment) that shall cause such Disallowance or Inclusion; (ii) the payment by Lessor to the Internal Revenue Service or any state or local taxing authority of the tax increase resulting from such Disallowance or
Inclusion; (iii) the adjustment of the tax return of Lessor to reflect such Disallowance or Inclusion; or (iv) Lessor’s receipt of 

  

 19 

 
written advice from its legal or tax advisers that a payment or Inclusion as contemplated by this Section 13.3 is required. The occurrence of a
Disallowance or Inclusion and the amount payable to Lessor under this Section 13.3 shall be calculated by certified public accountants selected by Lessor, and such calculation shall be binding and conclusive on Lessor and Lessee. 
 (d) Lessee and Lessor hereby agree that if, after the date of this Lease, there is any change in the Code or the regulations promulgated hereunder, or in
any state or local income tax laws or regulations (including the introduction of any new income tax law or any change in the maximum marginal federal, state or local income tax rate from time to time applicable to corporations or limited
partnerships) that would reduce the after-tax return that Lessor would have obtained if such change in law or regulation had not occurred, the Rent specified in this Lease shall be increased by an amount that, in the reasonable opinion of Lessor,
will cause Lessor after-tax return over the Term specified in this Lease to equal the after-tax return that Lessor would have obtained if such change in law or regulation had not occurred (the “Adjusted Payment”). After such
a change in law or regulation, Lessor shall provide Lessee written notice of such change in law or regulation, which notice shall contain the amount of any increase in Rent as the result of this paragraph. Rent shall be increased by the amount
stated in such written notice to Lessee as of the date specified in such notice as the date the Adjusted Payment becomes effective. It is the express intent and purpose of this paragraph to allocate to Lessee all risk resulting from any change in
law or regulation that would have the effect of reducing Lessor after-tax return resulting from the purchase of the Equipment and the leasing thereof to Lessee hereunder. The Indemnities set forth in this Section 13.3 are continuing indemnities
and shall survive expiration, termination, or cancellation. 
 Section 14. Insurance. 
 14.1 Insurance Policies. Lessee, shall maintain, or cause to be maintained, at no expense to Lessor, the following insurance: 
 (a) All-Risk first party property insurance covering the Equipment for any physical loss or damage to the Equipment (or any portion thereof),
including loss or damage caused, in whole or in part, by fire, water, wind, collapse, theft, vandalism, malicious mischief, collision and other risks normally included in extended All-Risk property coverage in an amount not less than greater of:
(i) the full replacement cost of the Equipment, and (ii) the Casualty Value of the Equipment 
 (b) A Comprehensive Liability
Insurance Policy in form and substance acceptable to Lessor and including a waiver of subrogation endorsement in favor of Lessor. The Comprehensive Liability Insurance Policy must be written with a limit of liability satisfactory to Lessor in its
sole and absolute discretion covering all sums Lessee and/or Lessor shall become legally obligated to pay as damages for bodily injury, including bodily injury, sickness, disease or death, or property damage, including loss of use, arising, directly
or indirectly, in connection with the Equipment, including contractual liability coverage in support of Lessee’s indemnification agreements in favor of Lessor. 
 (c) Workers’ Compensation Insurance Policies covering Lessee’s employees in an amount not less than the statutory limits for the State of where the Equipment is located (as may be amended from time to time),
including Employer’s Liability Insurance with limits of liability of not less than (i) One Million Dollars ($1,000,000) for bodily injury by accident, each accident, (ii) One Million Dollars ($1,000,000) for bodily injury by disease,
each employee, and (iii) One Million Dollars ($1,000,000) aggregate liability for disease. The Workers’ Compensation & Employer’s Liability Insurance Policies must each include a waiver of subrogation endorsement in favor of
Lessor. 
 (d) Excess Liability Insurance, if any is provided by Lessee in satisfaction of its obligations hereunder or is required by Lessor
in its sole and absolute discretion , shall specifically identify each of the policies described above in (a) and (b) of this Section 14.1 on the Schedule of Underlying Coverages, and shall provide and include as insured any party
insured under the policies described above, coverage that follows the form of each of the underlying policies. 
  

 20 

 14.2 Additional Insurance Provisions. All policies shall include Lessor and such
other parties as Lessor may designate and their respective officers, directors, partners, employees, agents, and consultants as loss payees and additional insureds to the insurance policies described below (excluding the Liability and Workers’
Compensation Policies). The insurance coverage afforded under the policies described herein shall be primary and non-contributing with respect to any insurance carried independently by the additional insureds. All such insurance policies shall
indicate that as respects the insureds (whether named or otherwise), cross-liability and severability of interests shall exist for all coverages provided thereunder. All policies of insurance required under this Section 14 shall be written on
an “occurrence” basis except as otherwise agreed by Lessor in its sole and absolute discretion. The insurance specified below shall be placed with insurance companies reasonably acceptable to Lessor (which companies shall, at a minimum,
have a rating of “B+10” or better by A.M. Best Company unless otherwise agreed by Lessor), and shall incorporate a provision requiring the giving of notice to Lessor at least thirty (30) days prior to the cancellation, non-renewal or
material modification of any such policies. Upon execution hereof, and periodically thereafter, including upon renewal, as required to demonstrate that insurance coverage is in effect, Lessee shall provide to Lessor, certified copies of all
certificates with respect to insurance required under this Section 14, stating the name of insurance company, policy number, expiration date, that Lessor is named as additional insured and loss payee (where applicable), and the coverage and
limits of liability with respect to each such insurance policy, all in a form reasonably acceptable to Lessor. All dollar amounts expressed in this Section 14 or approved by Lessor shall be updated every five (5) years based on the
then-current market conditions. Lessee shall not make adjustments in amounts greater than $100,000 with insurers except with Lessor’s prior written consent and hereby appoints Lessor as Lessee’s attorney-in-fact to receive payment of and
to endorse all checks, drafts and other documents and to take any other actions necessary to pursue insurance claims and recover payments pursuant to the insurance policies required hereunder if Lessee fails to do so (this power being coupled with
an interest and irrevocable for the term of this Lease). Lessee shall promptly notify Lessor of any occurrence which may become the basis of a claim and shall provide Lessor with all requested pertinent data. 
 Section 15. Default 
 15.1

payment’s due date; (b) Lessee fails (i) to provide Lessor with any notice required hereunder or (ii) to maintain insurance in accordance with Section 14 of this Lease; (c) Lessee breaches its obligations under
Section 11 of this Lease; (d) any default occurs under any Lease Document; (e) any default by Lessee occurs under any Permitted Use Agreement provided, however that, it shall not be an Event of Default for an additional thirty

insolvent, makes an assignment for the benefit of creditors or files any petition or action under any bankruptcy, reorganization, insolvency or moratorium law, or any other law or laws for the relief of, or relating to, debtors; (g) Lessee

observe or perform any covenant, agreement, or warranty made by Lessee in this Lease and the failure continues for ten (10) days after Lessor provides written notice thereof to Lessee; (j) Lessee or Parent defaults under any agreement for
money borrowed or the lease of real or personal property, which default Lessor reasonably determines, taking into account all relevant facts and 

  

 21 

 
circumstances known to Lessor including the nature and amount of financial exposure, would have a material adverse effect on: (A) Lessee’s ability
to pay or perform its Obligations; (B) Lessee’s ability to perform its duties under the Permitted Use Agreements or to receive any payments due to Lessee thereunder; (C) the business, assets, operations or financial or other condition

Control as to which it has not received Lessor’s consent as provided in Section 10.3. Lessee acknowledges that an Event of Default under any Lease shall constitute an Event of Default under all Leases. 
 15.2 Remedies. Upon the occurrence of any Event of Default, Lessor shall have any and all remedies existing at law, or in equity, and shall
have the right, at its sole option, at any time to exercise any or all of such remedies concurrently, successively or separately, without notice to Lessee (unless specifically stated herein). Without limiting its right to seek any and all remedies
existing, upon the occurrence of an Event of Default, Lessor, in its absolute and sole discretion, may: (a) proceed by court action to enforce performance by Lessee of the covenants and terms of this Lease; (b) require Lessee to make the
Equipment available to Lessor pursuant to Section 5.4 hereof; (c) immediately and without legal proceedings or notice or liability to Lessor, enter the premises, take possession of or remove and retain or make inoperable the Equipment or

due and payable; (e) by written notice to Lessee, terminate this Lease, in which event all rights of Lessee to use the Equipment shall terminate; provided, however, that in such event Lessee shall remain liable for all damages as provided
herein and provided, further that no notice shall be required upon the occurrence of an Event of Default under Section 15.1(f) or (m) hereof and such remedy shall be automatic; and/or (f) recover, as damages for loss of the bargain
and not as a penalty, the sum of (i) any accrued and unpaid Rent and other amounts due hereunder, plus (ii) the Casualty Value of the Equipment, plus (iii) an amount reasonably calculated by Lessor to give Lessor all of the benefits

reasonable professional fees and costs. Lessor shall have no liability by reason of any entry, repossession, or removal of all or any portion of the Equipment performed in accordance with Applicable Law. Upon the written demand of Lessor, Lessee
shall return the Equipment promptly to Lessor, in the manner and condition required by, and otherwise in accordance with the provisions of, Section 5.4 hereof.

whatsoever arising from said transfer or assignment. 
 15.4 Lessor Right to Perform. If Lessee fails to perform any of its
Obligations under this Lease, Lessor, in its sole and absolute discretion, may perform any such or all of the Obligations, and the expenses incurred by Lessor as a result thereof shall be payable by Lessee upon demand. In no event shall Lessor be
obligated to perform any of Lessee’s Obligations with respect to this Lease. 
  

 22 

 15.5 Repayment; Setoff. Lessee hereby grants Lessor and Lessor’s successors and
assigns (including any affiliate or subsidiary of Lessor) the right to apply, at any time and from time to time should an Event of Default exist hereunder, any and all obligations owing from Lessor (or its assignees hereunder) to Lessee toward
repayment of any sums owing from Lessee to Lessor hereunder. Lessee shall not have any right of setoff and hereby waives any such right of setoff or reduction due to any reason whatsoever. 
 15.6 Cumulative Remedies. The remedies provided to Lessor shall be cumulative and shall be in addition to all other remedies existing at
law or in equity. 
 Section 16. Miscellaneous 
 16.1 Further Assurances; Power of Attorney. Lessee will, upon demand of Lessor, at Lessee’s sole cost and expense, do and perform any other act and will execute, acknowledge, deliver, file,
register, communicate, record and deposit (and will re-file, re-register, re-communicate, re-record or re-deposit whenever required) any and all further documents, instruments or records required by law or reasonably requested by Lessor including
financing statements or other records under the UCC as currently in force or as subsequently revised or re-enacted, mortgages and other recordations (which Lessor shall have the right to file, communicate or record wherever and whenever Lessor deems
prudent for the purpose of proper protection, to the satisfaction of Lessor, of Lessor’s title and precautionary security interest in the Equipment or to carry out the provisions of this Lease.) Lessee further authorizes Lessor, and irrevocably
appoints Lessor as its attorney-in-fact (coupled with an interest) to enter ministerial information on any Schedule or other writing executed in connection with the Lease, to file financing statements or to execute and deliver or otherwise

authorizes Lessor to transmit and file any such statements, ministerial changes, and other items by electronic means. 
 16.2 No Merger
of Title. There shall be no merger of this Lease or of the leasehold estate created hereby by reason of the fact that the same Person may acquire, own or hold, directly or indirectly, in whole or in part, (a) this Lease or the leasehold
estate created hereby or any interest in this Lease or such leasehold estate, or (b) any right, title or interest in the Equipment. 
 16.3 Effect of Delay. A delay or omission by Lessor to exercise any right, power or remedy hereunder shall not impair the right, power or remedy and shall not be construed to be a waiver of any breach or default. Any waiver or
consent by Lessor of or to any breach or default must be in writing. 
 16.4 Severability and Survival. If any provision of
this Lease shall be invalid under any Applicable Law, it shall be inapplicable and deemed omitted but the remaining provisions shall be given effect in accordance with the intent of the Lease. All Obligations of Lessee under this Lease and the Lease
Documents shall survive the expiration or termination of this Lease to the extent required for their full observance and performance. 
 16.5
Amendment or Modification of Lease. The terms of this Lease may not be amended, waived, modified, or terminated except by written instrument signed by the parties hereto. No such amendment or waiver shall extend to or affect any
Obligation not expressly amended or waived or impair any right consequent thereon. In the event an amendment to any of the Lease Documents is required, in Lessor’s sole discretion, due to any request, action or inaction of Lessee, including any
voluntary or mandatory prepayment of the payment obligations, Lessee shall reimburse Lessor for all costs and expenses associated with such amendment, including the reasonable fees and out-of-pocket expenses of outside counsel for Lessor and the
reasonable travel costs of Lessor’s in-house counsel with respect thereto.

counsel (excluding any internal allocated charges of Lessor’s in-house counsel) with respect thereto and with respect to advising Lessor as to its rights and responsibilities under this Lease and the other Lease Documents. Lessee also agrees to
pay on demand all losses, costs and expenses, if any (including any and all fees and out-of-pocket expenses of counsel and Lessor’s engineer, including travel costs), incurred in connection with the preservation of any rights of Lessor under,
or the enforcement of, or legal advice in respect of, the rights or responsibilities of Lessor under this Lease or the Lease Documents, including losses, costs and expenses sustained by Lessor as a result of any failure by Lessee to perform or
observe its Obligations contained herein or any other document related hereto. 
 16.7 Interpretation. Any use of the term
“Equipment” herein shall be deemed to refer equally to the Equipment and all other parts of the Equipment, it being the understanding of the parties that any reference to “Equipment” shall not be deemed to prejudice any right of
Lessor hereunder to require performance as to each and every part of the Equipment and any reference to “Equipment” shall not be deemed to prejudice any right of Lessor to require performance as to all of the Equipment. All references to
Sections herein, unless otherwise stated, shall refer to Sections of this Master Lease. Nothing herein shall be deemed to provide or imply that Lessor is a “merchant” as to any item within the meaning of the UCC as currently in force or as
subsequently revised or re-enacted. The terms “herein” or “hereunder” or like terms shall be deemed to refer to this Lease as a whole and not to a particular section. Whenever terms such as “include” or
“including” are used in this Lease, they mean “include” or “including”, as the case may be, without limiting the generality of any description or word preceding such term. Whenever the expression “satisfactory to
Lessor”, “in Lessor’s judgment” or similar words are used or Lessor is granted the contractual or other right to choose between alternatives or to express its opinion, the satisfaction, judgment, choices and opinions are to be
made in Lessor’s sole discretion. The captions or headings in this Lease are made for convenience and general reference only and shall not be construed to describe, define, or limit the scope or intent of the provisions of this Lease. This
Lease has been drafted by counsel for Lessor as a convenience to the parties only and shall not, by reason of such action, be construed against Lessor or any other party. Lessee acknowledges and agrees that it has had full opportunity to review this
Lease and has had access to counsel of its choice to the extent it deems necessary in order to interpret the legal effect hereof. As used herein, all masculine pronouns shall include the feminine or neuter, and all singular terms the plural form
thereof, and vice versa. The exhibits annexed hereto are incorporated herein by this reference and made a part hereof as if contained in the body of this Lease. All references to sections hereunder shall be deemed to refer to sections of this Lease,
unless otherwise expressly provided, whether or not “hereof”, “above”, “below” or like words are used.
