 Ladies and Gentlemen: 

Introductory. Compressco Partners, L.P., a Delaware limited partnership (the “Partnership”), and Compressco Finance
Inc., a Delaware corporation (“Finance Corp.” and, together with the Partnership, the “Issuers”), propose to issue and sell to Merrill Lynch, Pierce, Fenner & Smith Incorporated (“Merrill

principal amount of the Issuers’ 7.25% Senior Notes due 2022 (the “Notes”). Merrill Lynch has agreed to act as the representative of the several Initial Purchasers (the “Representative”) in connection with the
offering and sale (the “Offering”) of the Notes and the Guarantees (as defined below). 
 The Securities (as
defined below) will be issued pursuant to an indenture, to be dated as of the Closing Date (as defined in Section 2 hereof) (the “Indenture”), among the Issuers, the Guarantors (as defined below) and U.S. Bank National
Association, as trustee (the “Trustee”). The Notes will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a letter
of representations, to be dated on or before the Closing Date (the “DTC Agreement”), from the Issuers to the Depositary. 

The holders of the Notes will be entitled to the benefits of a registration rights agreement, to be dated as of the Closing Date (the
“Registration Rights Agreement”), among the Issuers, the Guarantors and the Initial Purchasers, pursuant to which the Obligors (as defined below) may be required to file with the SEC (as defined below), under the circumstances set
forth therein, (i) a registration statement under the Securities Act of 1933 (as amended, the “Securities Act,” which term, as used herein, includes the rules and regulations of the Securities and Exchange Commission (the
“SEC”) promulgated thereunder) relating to another series of debt securities of the Issuers with terms substantially identical to the Notes (the “Exchange Notes”) to be offered in exchange for the Notes (the
“Exchange Offer”) or (ii) a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its commercially reasonable efforts to cause
such registration statements to be declared effective. All references herein to the Exchange Notes and the Exchange Offer are only applicable if the Obligors are in fact required to consummate the Exchange Offer pursuant to the terms of the
Registration Rights Agreement. 
 The payment of principal of, and premium, if any, and interest on, the Notes and the Exchange Notes
will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally, by (i) the entities listed on the signature pages hereof as “Guarantors” and (ii) any subsidiary of the Partnership formed or
acquired after the Closing Date that guarantees the Notes 







 
or the Exchange Notes in accordance with the terms of the Indenture, and their respective successors and assigns (collectively, the “Guarantors”), pursuant to their
guarantees of the Notes to be included in the Indenture (the “Guarantees”). The Notes and the Guarantees related thereto are herein collectively referred to as the “Securities”; the Exchange Notes and
the Guarantees related thereto are herein collectively referred to as the “Exchange Securities”; and the Issuers and the Guarantors are herein collectively referred to the “Obligors.” 

Compressco Partners Sub, Inc., a Delaware corporation (the “Purchaser”), has entered into that Stock Purchase Agreement,
dated as of July 20, 2014 (the “Stock Purchase Agreement”), with Warren Equipment Company, a Delaware corporation (the “Shareholder”), pursuant to which the Shareholder agreed to sell, and the Purchaser
agreed to acquire (the “Acquisition”), all of the issued and outstanding capital stock of Compressor Systems, Inc., a Delaware corporation (the “Target”). On the Closing Date, immediately following consummation of
the Acquisition, the Target and any additional entities required to guarantee the Notes pursuant to the Indenture (collectively, the “Additional Guarantors”) will be joined as parties to this Purchase Agreement (this
“Agreement”) pursuant to a joinder agreement, the form of which is attached hereto as Exhibit B (the “Joinder Agreement”). From and after the time of execution of the Joinder Agreement, all references herein to the
“Guarantors” will be deemed to include the Additional Guarantors (unless the context requires otherwise). 
 The Securities
are being issued and sold as part of a financing of the Acquisition, the costs and expenses related to the Transactions (as defined below), and the ongoing working capital and other general partnership purposes of the Partnership. In addition to the
Offering, the Purchaser intends to finance the Transactions from the following sources: (i) a concurrent registered offering of the Partnership’s common units representing limited partner interests (the “Equity Offering”);
and (ii) initial borrowings under the Partnership’s new credit agreement (the “New Credit Agreement”). The Acquisition, the issuance and sale of the Notes, the issuance of the Guarantees, the Equity Offering, the entry by
the Obligors into the New Credit Agreement and the initial extensions of credit thereunder, if any, on the Closing Date, the repayment in full of borrowings under the Partnership’s existing credit agreement (the “Existing Credit
Agreement”) as described in the Pricing Disclosure Package (as defined below) and the payment of transaction costs are referred to herein collectively, as the “Transactions.” 

This Agreement, the Registration Rights Agreement, the DTC Agreement, the Securities, the Exchange Securities, the New Credit Agreement, the
Joinder Agreement and the Indenture are referred to herein as the “Transaction Documents.” 
 The Issuers
understand that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agree that the Initial Purchasers may resell, subject
to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made is
referred to as the “Time of Sale”). The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the SEC under the Securities Act, in reliance upon exemptions therefrom. Pursuant to
the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that the Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale
under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) or Regulation S under
the Securities Act (“Regulation S”)).

performance of the Transaction Documents by the Obligors party thereto and the consummation of the transactions contemplated thereby (including the issuance and sale of the Securities and the use of proceeds from the sale of Securities as described
in the Offering Memorandum under the caption “Use of Proceeds”) (i) will not result in any violation of the Organizational Documents of the Obligors, (ii) except as disclosed in the Offering Memorandum, will not conflict with or

the accuracy of the representations and warranties of the Initial Purchasers set forth in Section 2 hereof and subject to compliance by the Initial Purchasers with the procedures set forth in Section 7 hereof, no consent, approval,
authorization or other order of, or registration or filing with, any court or other governmental or regulatory authority or agency is required for the execution, delivery and performance of the Transaction Documents by the Obligors to the extent a

to perfect liens or security interests granted in connection with the Transactions as contemplated by the Transaction Documents or the Offering Memorandum. As used herein, a “Debt Repayment Triggering Event” means any event or
condition that gives, or with the giving of notice or lapse of time would give, the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption

which infringement or conflict, if the subject of an unfavorable decision, would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change. 

(s) All Necessary Permits, etc. Except as otherwise disclosed in the Offering Memorandum, each of the Partnership
and its subsidiaries possesses such valid and current certificates, authorizations or permits issued by the appropriate state, federal or foreign regulatory agencies or bodies as are necessary under applicable law to own, lease and operate its
properties and to conduct its businesses, except where the failure to obtain such certificates, authorizations or permits would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change. Neither the
Partnership nor any of its subsidiaries has received any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit, which if the subject of an unfavorable decision,
ruling or finding, would reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change.

 10 








 
Material Adverse Change. The real property, improvements, equipment and personal property held under lease by the Partnership or any subsidiary are held under valid and enforceable leases, with
such exceptions to validity and enforceability as would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change. 

(u) Tax Law Compliance. The Partnership and its subsidiaries that are required to do so have filed (or have
obtained an extension with respect to) all federal, state, local and foreign income and franchise tax returns (other than certain state and local tax returns as to which the failure to file would not reasonably be expected, individually or in the
aggregate, to result in a Material Adverse Change) and have paid all taxes required to be paid and due pursuant to such return and, if due and payable, any related or similar assessment, fine or penalty levied against any of the Partnership or its
subsidiaries, in each case other than those (i) that are being contested in good faith and for which adequate reserves have been established in accordance with GAAP or (ii) which, if not paid, would not reasonably be expected, individually

amount of liabilities (including contingent liabilities) of such person, (ii) the present fair salable value of the assets of such person is greater than the amount that will be required to pay the probable liabilities of such person on its
debts as they become absolute and matured, (iii) such person is able to realize upon its assets and pay its debts and other liabilities, including contingent obligations, as they mature and (iv) such person does not have unreasonably small
capital.

corporation and the sole general partner of the Partnership (the “General Partner”), and the General Partner’s officers and directors, in their capacities as such, are in compliance with the applicable provisions of the
Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act,” which term, as used herein, includes the rules and regulations of the SEC promulgated thereunder). 

  
 11 








 (aa) Accounting System. The Partnership maintains a system of
accounting controls that is sufficient to provide reasonable assurances that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; (iv) the recorded
accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (v) the interactive data in eXtensible Business Reporting Language incorporated by reference
in the Offering Memorandum and the Pricing Disclosure Package fairly present the information called for in all material respects and are prepared in accordance with the SEC’s rules and guidelines applicable thereto. 

(bb) Disclosure Controls and Procedures. The Partnership has established and maintains “disclosure controls
and procedures” (as such term is defined in Rules 13a-15 and 15d-15 under the Exchange Act); such disclosure controls and procedures (i) are designed to provide reasonable assurance that material information relating to the
Partnership and its subsidiaries is made known to the chief executive officer and chief financial officer of the General Partner as appropriate by others within the General Partner, the Partnership or its subsidiaries and (ii) are effective in
all material respects to perform the functions for which they are established subject to the limitations of any such control system; the Company’s auditors and the Audit Committee of the Board of Directors of the General Partner have been
advised of: (x) any significant deficiencies or material weaknesses in the design or operation of internal controls which could adversely affect the Partnership’s ability to record, process, summarize, and report financial data; and
(y) any fraud, whether or not material, that involves management or other employees who have a role in the Partnership’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there
have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses. 

(cc) Regulations T, U and X. None of the Obligors nor any of their respective subsidiaries nor any agent thereof
acting on their behalf has taken, and none of them will take, any action that might cause this Agreement or the issuance or sale of the Securities to violate Regulation T, Regulation U or Regulation X of the Board of Governors of the Federal Reserve
System. 
 (dd) Compliance with and Liability Under Environmental Laws. Except as otherwise disclosed in the
Offering Memorandum or as would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change: (i) each of the Partnership and its subsidiaries and their respective operations and facilities are in
compliance with, and not subject to any known liabilities under, applicable Environmental Laws (as defined below), which compliance includes, without 

  
 12 








 
limitation, having obtained and being in material compliance with any permits, licenses or other governmental authorizations or approvals, and having made all filings and provided all financial
assurances and notices, required for the ownership and operation of the business, properties and facilities of the Partnership or its subsidiaries under applicable Environmental Laws, and compliance with the terms and conditions thereof;
(ii) neither the Partnership nor any of its subsidiaries has received any written communication, whether from a governmental authority, citizens group, employee or otherwise, that alleges that the Partnership or any of its subsidiaries is in
violation of any Environmental Law; (iii) there is no claim, action or cause of action filed with a court or governmental authority, no investigation with respect to which the Partnership has received written notice, and no written notice by
any person or entity alleging actual or potential liability on the part of the Partnership or any of its subsidiaries based on or pursuant to any Environmental Law pending or, to the Partnership’s knowledge, threatened against the Partnership
or any of its subsidiaries other than such claims, actions, causes of action, investigations and notices regarding which it is reasonably believed no monetary sanctions of $100,000 or more will be imposed; (iv) other than in the ordinary course
of business, neither the Partnership nor any of its subsidiaries is conducting or paying for, in whole or in part, any investigation, response or other corrective action pursuant to any Environmental Law at any site or facility, nor is any of them
subject or a party to any order, judgment, decree, contract or agreement which imposes any obligation or liability under any Environmental Law other than such investigations, responses or other corrective actions regarding which it is reasonably
believed no monetary sanctions of $100,000 or more will be imposed; and (v) there are no past or present actions, activities, circumstances, conditions or occurrences, including, without limitation, the Release (as defined below) or threatened
Release of any Materials of Environmental Concern (as defined below), that could reasonably be expected to result in a violation of or liability under any Environmental Law on the part of the Partnership or any of its subsidiaries, including without
limitation, any such liability which the Partnership or any of its subsidiaries has retained or assumed either contractually or by operation of law. 

For purposes of this Agreement, “Environment” means ambient air, indoor air, surface water,
groundwater, drinking water, soil, surface and subsurface strata, and natural resources such as wetlands, flora and fauna. “Environmental Laws” means the common law and all federal, state, local and foreign laws or regulations,
ordinances, codes, orders, decrees, judgments and injunctions issued, promulgated or entered thereunder, relating to pollution or protection of the Environment or human health, including without limitation, those relating to (x) the Release or
threatened Release of Materials of Environmental Concern; and (y) the manufacture, processing, distribution, use, generation, treatment, storage, transport, handling or recycling of Materials of Environmental Concern. “Materials of
Environmental Concern” means any substance, material, pollutant, contaminant, chemical, waste, compound, or constituent, in any form, including without limitation, petroleum and petroleum products, subject to regulation or which can give
rise to liability under any Environmental Law. “Release” means any release, spill, emission, discharge, deposit, disposal, leaking, pumping, pouring, dumping, emptying, injection or leaching into the Environment, or into, from or
through any building, structure or facility. 

  
 13 








 (ee) Periodic Review of Costs of Environmental Compliance. In the
ordinary course of its business, the Partnership conducts a periodic review of the effect of Environmental Laws on the business, operations and properties of the Partnership and its subsidiaries, in the course of which it identifies and evaluates
associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on
operating activities and any potential liabilities to third parties). On the basis of such review and the amount of its established reserves, the Partnership has reasonably concluded that such associated costs and liabilities would not, individually
or in the aggregate, result in a Material Adverse Change. 
 (ff) ERISA Compliance. Except as otherwise
disclosed in the Offering Memorandum, the Partnership and its subsidiaries and any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974 (as amended, “ERISA,” which term, as used
herein, includes the regulations and published interpretations thereunder) established or maintained by the Partnership, its subsidiaries or their ERISA Affiliates (as defined below) are in compliance with ERISA, except for where any failure to
comply would not reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change. “ERISA Affiliate” means, with respect to the Partnership or a subsidiary, any member of any group of organizations
described in Section 414 of the Internal Revenue Code of 1986 (as amended, the “Internal Revenue Code,” which term, as used herein, includes the regulations and published interpretations thereunder) of which the Partnership or
such subsidiary is a member. No “reportable event” (as defined under ERISA but excluding any event for which the 30-day notice period is waived) has occurred that has not been timely reported or is reasonably expected to occur with respect
to any “employee benefit plan” established or maintained by the Partnership, its subsidiaries or any of their ERISA Affiliates. No “employer pension benefit plan” (as defined under ERISA) established or maintained by the
Partnership, its subsidiaries or any of their ERISA Affiliates, if such “employer pension benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA), except as would not
reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change. Neither the Partnership, its subsidiaries nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability that would
reasonably be expected, individually or in the aggregate, to result in a Material Adverse Change under either (i) Title IV of ERISA with respect to termination of, or withdrawal from, any “employer pension benefit plan” or
(ii) Sections 412, 4971, 4975 or 4980B of the Internal Revenue Code. Each “employer pension benefit plan” established or maintained by the Partnership, its subsidiaries or any of their ERISA Affiliates that is intended to be qualified
under Section 401 of the Internal Revenue Code is so qualified and nothing has occurred, whether by action or failure to act, that would cause the loss of such qualification. 

(gg) Compliance with Labor Laws. Except as otherwise disclosed in the Offering Memorandum or as would not reasonably be
expected, individually or in the aggregate, to result in a Material Adverse Change, (i) there is (A) no unfair labor practice complaint pending or, to the knowledge of the Partnership, threatened against the


  
 14 








 
Partnership or any of its subsidiaries before the National Labor Relations Board, and no grievance or arbitration proceeding arising out of or under collective bargaining agreements pending, or
to the knowledge of the Partnership, threatened, against the Partnership or any of its subsidiaries, (B) no strike, labor dispute, slowdown or stoppage pending or, to the knowledge of the Partnership, threatened against the Partnership or any
of its subsidiaries and (C) no union representation question existing with respect to the employees of the Partnership or any of its subsidiaries and, to the knowledge of the Partnership, no union organizing activities taking place and
(ii) there has been no violation of any federal, state or local law relating to discrimination in hiring, promotion or pay of employees or of any applicable wage or hour laws. 

(hh) Related Party Transactions. No relationship, direct or indirect, exists between any of the Partnership or
its Affiliates, on the one hand, and the directors, officers, unitholders, customers or suppliers of any of the Partnership or its Affiliates, on the other hand, that is required by the Securities Act to be disclosed in a registration statement on
Form S-1 to be filed with the SEC and that is not so disclosed in the Offering Memorandum. There are no outstanding loans, advances (except advances for business expenses in the ordinary course of business) or guarantees of indebtedness by the
Obligors or their Affiliates to or for the benefit of any of the officers or directors of the Obligors or their Affiliates or any of their respective family members.  

(ii) No Unlawful Contributions or Other Payments. Neither the Partnership nor any of its subsidiaries nor any
director or officer of the foregoing entities, or, to the knowledge of the Partnership, any agent, employee or affiliate of the Partnership or any of its subsidiaries is aware of or has taken any action, directly or indirectly, that would result in
a violation by such persons of the Foreign Corrupt Practices Act of 1977 (as amended, the “FCPA,” which term, as used herein, includes the rules and regulations thereunder), including, without limitation, making use of the mails or
any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of
value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA and the Partnership, its subsidiaries and,
to the knowledge of the Partnership, their Affiliates have conducted their businesses in compliance with the FCPA and have instituted and maintain and enforce policies and procedures designed to ensure, and which are reasonably expected to continue
to ensure, continued compliance therewith. 
 (jj) No Conflict with Money Laundering Laws. The
operations of the Partnership and its subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended,
the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any governmental agency (collectively, the
“Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Partnership or any of its subsidiaries with respect to the Money Laundering
Laws is pending or, to the knowledge of the Partnership, threatened. 

  
 15 








 (kk) OFAC. Neither the Partnership nor any of its subsidiaries nor
any director or officer of the foregoing entities, or, to the knowledge of the Partnership, any agent, employee or affiliate of the Partnership or any of its subsidiaries is currently subject to any U.S. sanctions administered by the Office of
Foreign Assets Control of the U.S. Treasury Department (“OFAC”), the U.S. Department of Commerce, the U.S. Department of State, the United Nations Security Council, the European Union, Her Majesty’s Treasury, or other relevant
sanctions authority (collectively, “Sanctions”), nor is the Partnership or any of its subsidiaries located, organized or resident in a country or territory that is the subject of Sanctions. The Obligors will not, directly or
indirectly, use the proceeds of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person, (i) to fund any activities of or business with any person that, at the time of
such funding, is the subject of Sanctions, or is in Burma/Myanmar, Cuba, Iran, Libya, North Korea, Sudan or in any other country or territory, that, at the time of such funding, is the subject of Sanctions, or (ii) in any manner that will
result in a violation by any person (including any person participating in the offering, whether as underwriter, advisor, investor or otherwise) of any U.S. sanctions administered by OFAC. 

(ll) New Credit Agreement. The New Credit Agreement has been duly and validly authorized by the Obligors and,
when duly executed and delivered by the Obligors and duly authorized, executed and delivered by the lenders thereunder, will be the valid and legally binding obligation of the Obligors, enforceable against the Obligors in accordance with its terms,
except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles. 

(mm) Regulation S. The Obligors and their respective Affiliates and all persons acting on their behalf (other
than the Initial Purchasers, as to whom the Obligors make no representation) have complied with and will comply with the offering restrictions requirements of Regulation S in connection with the offering of the Securities outside the United
States and, in connection therewith, the Offering Memorandum will contain the disclosure required by Rule 902. The Partnership is a “reporting issuer”, as defined in Rule 902 under the Securities Act.  

(nn) Capitalization. The Partnership’s capitalization is as set forth under the caption
“Capitalization” in the Offering Memorandum. 
 (oo) MLP Status. The Partnership is properly
treated as a partnership for United States federal income tax purposes and has, for each taxable year beginning after December 31, 2010 during which the Partnership was in existence, met the gross income requirements of Section 7704(c)(2)
of the Code.

(A) within the United States, to persons whom it reasonably believes are “qualified institutional buyers” within the meaning of Rule 144A (“Qualified Institutional Buyers”) in transactions pursuant to and meeting the
requirements of Rule 144A, and in connection with each such sale, it has taken or will take reasonable steps to ensure that the purchaser of the Securities is aware that such sale is being made in reliance on Rule 144A and (B) outside the

 18 








 SECTION 3. Additional Covenants. Each of the Obligors further covenants and agrees
with each Initial Purchaser as follows: 
 (a) Preparation of Final Offering Memorandum; Initial
Purchasers’ Review of Proposed Amendments and Supplements and Additional Written Communications. As promptly as practicable following the Time of Sale and in any event not later than the second business day following the date hereof, the
Partnership will prepare and deliver to the Initial Purchasers the Final Offering Memorandum, which shall consist of the Preliminary Offering Memorandum as modified only by the information contained in the Pricing Supplement and any other
information that has been presented to the Representative or its counsel and as to which the Representative has not reasonably objected in writing. The Partnership will not amend or supplement the Preliminary Offering Memorandum or the Pricing
Supplement unless the Representative shall previously have been furnished a copy of the proposed amendment or supplement and shall not have reasonably objected in writing to such amendment or supplement. The Partnership will not amend or supplement
the Final Offering Memorandum prior to the Closing Date unless the Representative shall previously have been furnished a copy of the proposed amendment or supplement and shall not have reasonably objected in writing to such amendment or supplement.
Before making, preparing, using, authorizing, approving or distributing any Additional Written Communication, the Partnership will furnish to the Representative a copy of such written communication for review and will not make, prepare, use,
authorize, approve or distribute any such written communication to which the Representative reasonably objects in writing. 

(b) Amendments and Supplements to the Final Offering Memorandum and Other Securities Act Matters. If at any time
prior to the Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Pricing Disclosure Package, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (ii) it is necessary to amend or supplement any of the Pricing Disclosure Package to comply with
law, the Partnership will immediately notify the Representative thereof and forthwith prepare and (subject to Section 3(a) hereof) furnish to the Initial Purchasers such amendments or supplements to any of the Pricing Disclosure Package as may
be necessary so that the statements in any of the Pricing Disclosure Package, as so amended or supplemented, will not, in the light of the circumstances under which they were made, be misleading or so that any of the Pricing Disclosure Package will
comply with all applicable law. If, prior to the completion of the initial placement of the Securities by the Initial Purchasers with the Subsequent Purchasers, any event shall occur or condition exist as a result of which it is necessary to amend
or supplement the Final Offering Memorandum, as then amended or supplemented, in order to make the statements therein, in the light of the circumstances when the Final Offering Memorandum is delivered to a Subsequent Purchaser, not misleading, or if
in the judgment of the Representative or counsel for the Initial Purchasers it is otherwise necessary to amend or supplement the Final Offering Memorandum to comply with law, the Partnership agrees to promptly prepare (subject to Section 3
hereof) and furnish at its own expense to the Initial Purchasers, amendments or supplements to the Final Offering Memorandum so that the statements included or incorporated by reference in the Final Offering Memorandum as so amended or supplemented
will not, in the light of the circumstances at the Closing Date and at the time of sale of the Securities, be misleading or so that the Final Offering Memorandum, as amended or supplemented, will comply with all applicable law. 

  
 19 








 The Obligors hereby expressly acknowledge that the indemnification and
contribution provisions of Sections 8 and 9 hereof are specifically applicable and relate to each offering memorandum, amendment or supplement referred to in this Section 3. 

(c) Copies of the Offering Memorandum. The Partnership agrees to furnish the Initial Purchasers, without charge,
as many copies of the Pricing Disclosure Package and the Final Offering Memorandum and any amendments and supplements thereto as they shall reasonably request. 

(d) Blue Sky Compliance. Each of the Obligors shall cooperate with the Representative and counsel for the Initial
Purchasers to qualify or register (or to obtain exemptions from qualifying or registering) all or any part of the Securities for offer and sale under the securities laws of such jurisdictions reasonably designated by the Representative, shall comply
with such laws and shall continue such qualifications, registrations and exemptions in effect so long as required for the distribution of the Securities. Notwithstanding the foregoing sentence, none of the Obligors shall be required to qualify as a
foreign corporation or to take any action that would subject it to general service of process in any such jurisdiction where it is not presently qualified or where it would be subject to taxation as a foreign corporation. The Obligors will advise
the Representative promptly of the suspension of the qualification or registration of (or any such exemption relating to) the Securities for offering, sale or trading in any jurisdiction or any initiation or threat of any proceeding for any such
purpose, and in the event of the issuance of any order suspending such qualification, registration or exemption, each of the Obligors shall use its commercially reasonable efforts to obtain the withdrawal thereof at the earliest possible moment. 

 (e) Use of Proceeds. The Issuers shall apply the net proceeds from the sale of the Securities sold by
them in the manner described under the caption “Use of Proceeds” in the Pricing Disclosure Package. 

(f) The Depositary. The Partnership will cooperate with the Initial Purchasers and use its reasonable best
efforts to permit the Securities to be eligible for clearance and settlement through the facilities of the Depositary. 

(g) Additional Issuer Information. Prior to the completion of the initial placement of the Securities by the
Initial Purchasers with the Subsequent Purchasers, the Partnership shall file, on a timely basis, with the SEC and the Nasdaq Global Market (the “Nasdaq”) all reports and documents required to be filed under Section 13 or
Section 15 of the Exchange Act. For so long as any of the Securities remain outstanding, and are “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, at any time when the Partnership is not subject to
Section 13 or Section 15 of the Exchange Act, for the benefit of holders and beneficial owners from time to time of the Securities, the Partnership shall furnish, at its expense, upon request, to holders and beneficial owners of Securities
and prospective purchasers of Securities information satisfying the requirements of Rule 144A(d)(4) under the Securities Act. 

  
 20 








 (h) Agreement Not To Offer or Sell Additional Securities. During
the period of 60 days following the date hereof, the Issuers will not, without the prior written consent of Merrill Lynch (which consent may be withheld at the sole discretion of Merrill Lynch), directly or indirectly, sell, offer, contract or grant
any option to sell, pledge, transfer or establish an open “put equivalent position” within the meaning of Rule 16a-1 under the Exchange Act, or otherwise dispose of or transfer, or announce the offering of, or file any registration
statement under the Securities Act in respect of, any debt securities of the Issuers having a tenor of more than one year or securities exchangeable for or convertible into debt securities of the Issuers (other than as contemplated by this Agreement
and to register the Exchange Securities). 
 (i) No Integration. The Issuers agree that they will not
and will cause their Affiliates not to make any offer or sale of securities of the Issuers of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render
invalid (for the purpose of (i) the sale of the Securities by the Obligors to the Initial Purchasers, (ii) the resale of the Securities by the Initial Purchasers to Subsequent Purchasers or (iii) the resale of the Securities by such
Subsequent Purchasers to others) the exemption from the registration requirements of the Securities Act provided by Section 4(a)(2) thereof or by Rule 144A or by Regulation S thereunder or otherwise.  

(j) No General Solicitation or Directed Selling Efforts. The Issuers agree that they will not and will not permit
any of their Affiliates or any other person acting on their behalf (other than the Initial Purchasers, as to which no covenant is given) to (i) solicit offers for, or offer or sell, the Securities by means of any form of general solicitation or
general advertising within the meaning of Rule 502(c) of Regulation D or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act or (ii) engage in any directed selling efforts with respect to
the Securities within the meaning of Regulation S, and the Issuers will and will cause all such persons to comply with the offering restrictions requirement of Regulation S with respect to the Securities. 

(k) No Restricted Resales. Until consummation of the Exchange Offer, the Issuers will not, and will not permit
any of their affiliates (as defined in Rule 144 under the Securities Act) that they control to resell any of the Securities that constitute “restricted securities” under Rule 144(a)(3) under the Securities Act that have been reacquired by
any of them (other than pursuant to an effective registration statement under the Securities Act). 
 (l)
Legended Securities. Each certificate for a Note will bear the legend contained in “Notice to Investors” in the Preliminary Offering Memorandum for the time period and upon the other terms stated in the Preliminary Offering
Memorandum. 

  
 21 








 (m) Future Reports. While the Securities remain outstanding and are
“restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, the Issuers will, during any period in which the Partnership is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act,
furnish to holders of the Securities and prospective purchasers of the Securities designated by such holders, upon the request of such holders or such prospective purchasers, the information required to be delivered pursuant to Rule 144A(d)(4) under
the Securities Act. 
 The Representative, on behalf of the several Initial Purchasers, may, in its sole discretion, waive in writing
the performance by any of the Obligors of any one or more of the foregoing covenants or extend the time for their performance. 

SECTION 4. Payment of Expenses. Each of the Obligors, jointly and severally, agrees to pay all costs, fees and expenses incurred
in connection with the performance of its obligations hereunder and in connection with the transactions contemplated hereby, including, without limitation, (i) all expenses incident to the issuance and delivery of the Securities (including all
printing costs), (ii) all necessary issue, transfer and other stamp taxes in connection with the original issuance and sale of the Securities to the Initial Purchasers, (iii) all fees and expenses of the Obligors’ counsel, independent
public or certified public accountants and other advisors, (iv) all costs and expenses incurred in connection with the preparation, printing, filing, shipping and distribution of the Pricing Disclosure Package and the Final Offering Memorandum
(including financial statements and exhibits), and all amendments and supplements thereto, and the Transaction Documents (except as otherwise stated therein), (v) all filing fees and expenses incurred by the Obligors or the Initial Purchasers
in connection with qualifying or registering (or obtaining exemptions from the qualification or registration of) all or any part of the Securities for offer and sale under the securities laws of the jurisdictions reasonably designated by the Initial
Purchasers (including, without limitation, reasonable fees and expenses of counsel for the Initial Purchasers related to such qualification and registration, and the cost of preparing, printing and mailing preliminary and final blue sky or legal
investment memoranda and any related supplements to the Pricing Disclosure Package or the Final Offering Memorandum), (vi) the fees and expenses of the Trustee, including the fees and disbursements of counsel for the Trustee in connection with
the Indenture, the Securities and the Exchange Securities, (vii) any fees payable in connection with the rating of the Securities or the Exchange Securities with the ratings agencies, (viii) any filing fees incident to, and any reasonable
fees and disbursements of counsel to the Initial Purchasers in connection with the review by the Financial Industry Regulatory Authority, Inc. (“FINRA”), if any, of the terms of the sale of the Securities or the Exchange Securities,
(ix) all fees and expenses (including reasonable fees and expenses of counsel) of the Obligors in connection with approval of the Securities by the Depositary for “book-entry” transfer, and the performance by the Obligors of their
respective other obligations under this Agreement and (x) one-half of all expenses incident to the “road show” for the offering of the Securities, including the cost of any chartered airplane or other transportation used for the
purposes of the road show (with the Initial Purchasers to pay the remaining one-half of all expenses incident to the road show, including the cost of any chartered airplane or other transportation). Except as provided in this Section 4 and
Sections 6, 8 and 9 hereof, the Initial Purchasers shall pay their own expenses, including the fees and disbursements of their counsel. 

  
 22

of any of the representations and warranties, or the satisfaction of any of the conditions or agreements, herein contained. 
 If any
condition specified in this Section 5 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Representative by notice to the Issuers at any time on or prior to the Closing Date, which termination shall be
without liability on the part of any party to any other party, except that Sections 4, 6, 8 and 9 hereof shall at all times be effective and shall survive such termination. 

SECTION 6. Reimbursement of Initial Purchasers’ Expenses. If this Agreement is terminated by the Representative pursuant to
Section 5 or Section 10 hereof, including if the sale to the Initial Purchasers of the Securities on the Closing Date is not consummated because of any refusal, inability or failure on the part of the Obligors to perform any agreement
herein or to comply with any provision hereof, the Obligors agree, jointly and severally, to reimburse the Initial Purchasers, severally, upon demand for all out-of-pocket expenses that shall have been reasonably incurred by the Initial Purchasers
in connection with the proposed purchase and the offering and sale of the Securities, including, without limitation, fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges but excluding wages
and salaries paid by the Initial Purchasers. 
 SECTION 7. Offer, Sale and Resale Procedures. Each of the Initial
Purchasers, on the one hand, and each of the Obligors, on the other hand, hereby agree to observe the following procedures in connection with the offer and sale of the Securities: 

(a) Offers and sales of the Securities will be made only by the Initial Purchasers or Affiliates thereof qualified to do so in
the jurisdictions in which such offers or sales are made. Each such offer or sale shall only be made to persons whom the offeror or seller reasonably believes to be Qualified Institutional Buyers or non-U.S. persons outside the United States to whom
the offeror or seller reasonably believes offers and sales of the Securities may be made pursuant to and in reliance upon Regulation S upon the terms and conditions set forth in Annex II hereto, which Annex II is hereby expressly made a part hereof.


  
 25 








 (b) No general solicitation or general advertising (within the meaning of Rule
502 under the Securities Act) will be used in the United States in connection with the offering of the Securities. 
 (c)
Upon original issuance by the Issuers, and until such time as the same is no longer required under the applicable requirements of the Securities Act, the Notes (and all securities issued in exchange therefor or in substitution thereof, other than
the Exchange Notes) shall bear the following legend: 
 “THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS
AMENDED (THE “SECURITIES ACT”), OR ANY STATE OR OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE
ABSENCE OF SUCH REGISTRATION OR UNLESS THE TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT (A) IT IS A
“QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN “OFFSHORE TRANSACTION” PURSUANT TO RULE 903 OR RULE 904 OF REGULATION S,
(2) AGREES THAT IT WILL NOT, PRIOR TO THE DATE THAT IS ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF (OR OF ANY PREDECESSOR OF THIS SECURITY) AND THE LAST DATE ON WHICH COMPRESSCO PARTNERS, L.P. AND COMPRESSCO FINANCE INC. (THE
“ISSUERS”) OR ANY AFFILIATE OF THE ISSUERS WAS THE OWNER OF THIS SECURITY OR ANY PREDECESSOR OF THIS SECURITY, OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUERS OR ANY OF ITS SUBSIDIARIES, (B) PURSUANT TO
A REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL
BUYER” AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT
TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES WITHIN THE MEANING OF REGULATION S OR (E) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION 

  
 26 








 
REQUIREMENTS OF THE SECURITIES ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND; PROVIDED THAT THE
ISSUERS AND THE TRUSTEE SHALL HAVE THE RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER (I) PURSUANT TO CLAUSE (E) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM AND
(II) IN EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATION OF TRANSFER IN THE FORM APPEARING IN THE INDENTURE IS COMPLETED AND DELIVERED BY THE TRANSFER TO THE TRUSTEE.” 

Following the sale of the Securities by the Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers
shall not be liable or responsible to the Obligors for any losses, damages or liabilities suffered or incurred by the Obligors, including any losses, damages or liabilities under the Securities Act, arising from or relating to any resale or transfer
of any Security by such Subsequent Purchasers. 
 SECTION 8. Indemnification. 

(a) Indemnification of the Initial Purchasers. Each of the Obligors, jointly and severally, agrees to indemnify and hold
harmless each Initial Purchaser, its affiliates, directors, officers and employees, and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act
against any loss, claim, damage, liability or expense, as incurred, to which each Initial Purchaser, affiliate, director, officer, employee or controlling person may become subject under the Securities Act, the Exchange Act or other federal or state
statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Obligors or otherwise permitted by Section 8(d)), insofar as such loss, claim,
damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing
Supplement, any Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading; and to reimburse each Initial Purchaser and each such affiliate, director, officer, employee or controlling person for any and all expenses (including the reasonable fees and
disbursements of counsel chosen by Merrill Lynch) as such expenses are documented and reasonably incurred by such Initial Purchaser or such affiliate, director, officer, employee or controlling person in connection with investigating, defending,
settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that none of the Obligors shall be liable for any loss, claim, damage, liability, expense or other action to the extent, but only
to the extent, arising out of or based upon any 

  
 27 








 
untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of any
Initial Purchaser expressly for use in the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto). The indemnity agreement set forth in
this Section 8(a) shall be in addition to any liabilities that the Obligors may otherwise have. 
 (b)
Indemnification of the Obligors. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless each of the Obligors, each of their respective directors and officers, and each person, if any, who controls any of the
Obligors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss, claim, damage, liability or expense, as incurred, to which any Obligor or any such director, officer, employee or
controlling person may become subject under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with
the written consent of such Initial Purchaser or otherwise permitted by Section 8(d)), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon any untrue
statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto), or the
omission or alleged omission therefrom of 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 to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission was made in the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication or the Final Offering Memorandum (or any amendment or
supplement thereto), in reliance upon and in conformity with written information furnished to the Issuers by or on behalf of such Initial Purchaser expressly for use therein; and to reimburse each Obligor and each such director, officer, or
controlling person for any and all expenses (including the fees and disbursements of counsel) as such expenses are documented and reasonably incurred by the Obligors or such director, officer, or controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. Each of the Obligors hereby acknowledges that the only information that the Initial Purchasers have furnished to the Obligors expressly for use
in the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication or the Final Offering Memorandum (or any amendment or supplement thereto) are (i) the statements set forth in the third and fourth sentences of
the eighth paragraph under the caption “Important Notice to Readers” and (ii) the information set forth in the table in the first paragraph and the statements in the fifth paragraph, the third and fourth sentences of the seventh
paragraph, and the tenth through twelfth paragraphs under the caption “Plan of Distribution,” in each case of clauses (i) and (ii), in the Preliminary Offering Memorandum and the Final Offering Memorandum. The indemnity agreement set
forth in this Section 8(b) shall be in addition to any liabilities that each Initial Purchaser may otherwise have. 

  
 28 








 (c) Notifications and Other Indemnification Procedures. Promptly
after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the
indemnifying party in writing of the commencement thereof; provided that the failure to so notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party under this Section 8
except to the extent that it has been materially prejudiced by such failure (through the forfeiture of substantive rights and defenses) and shall not relieve the indemnifying party from any liability that the indemnifying party may have to an
indemnified party other than under this Section 8. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be
entitled to participate in and, to the extent that it shall elect, jointly with all other indemnifying parties similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying
party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses
available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and
to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense
of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the indemnifying party shall not
be liable for the expenses of more than one separate counsel (together with local counsel (in each jurisdiction)), which shall be selected by Merrill Lynch in the case of counsel representing the Initial Purchasers or their related persons,
representing the indemnified parties who are parties to such action, or (ii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice
of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying party. 

(d) Settlements. The indemnifying party under this Section 8 shall not be liable for any settlement of any
proceeding effected without its written consent, which will not be unreasonably withheld, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against
any loss, claim, damage, liability or expense by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified 

  
 29 








 
party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 8, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying
party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement. No indemnifying party shall, without
the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party
and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject
matter of such action, suit or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party. 

SECTION 9. Contribution. If the indemnification provided for in Section 8 hereof is for any reason held to be unavailable
to or otherwise insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount paid or payable by such
indemnified party, as incurred, as a result of any losses, claims, damages, liabilities or expenses referred to therein (i) in such proportion as is appropriate to reflect the relative benefits received by the Obligors, on the one hand, and the
Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement 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 Obligors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the statements or omissions that resulted in
such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Obligors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the
offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the
Issuers, and the total discount received by the Initial Purchasers bear to the aggregate initial offering price of the Securities. The relative fault of the Obligors, on the one hand, and the Initial Purchasers, on the other hand, shall be
determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Obligors, on the one hand, or the
Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. 

The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed
to include, subject to the limitations set forth in Section 8 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in
Section 8 hereof with respect to notice of commencement of any action shall apply if a claim for contribution is to be made under this Section 9; provided, however, that no additional notice shall be required with respect to
any action for which notice has been given under Section 8 hereof for purposes of indemnification. 

  
 30 








 The Obligors and the Initial Purchasers agree that it would not be just and equitable if
contribution pursuant to this Section 9 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 this Section 9. 
 Notwithstanding the provisions of this Section 9, no Initial Purchaser shall be
required to contribute any amount in excess of the total discount and commissions received by such Initial Purchaser in connection with the Securities distributed by it. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11 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 9 are several, and
not joint, in proportion to their respective commitments as set forth opposite their names in Schedule A. For purposes of this Section 9, each affiliate, director, officer and employee of an Initial Purchaser and each person, if any, who
controls an Initial Purchaser within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act shall have the same rights to contribution as such Initial Purchaser, and each director and officer of an Obligor, and
each person, if any, who controls the Obligors with the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act shall have the same rights to contribution as the Obligors, as applicable. 

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representative by
notice given to the Issuers if at any time: (i) trading or quotation in any of the Partnership’s securities shall have been suspended or materially limited by the SEC or by the Nasdaq, or trading in securities generally on either the
Nasdaq or the New York Stock Exchange shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on any of such quotation system or stock exchange by the SEC or FINRA; (ii) a general
banking moratorium shall have been declared by any of the federal, New York or Delaware authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity, or any change in
the United States or international financial markets, or any substantial change or development involving a prospective substantial change in United States’ or international political, financial or economic conditions, in each such case, as 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 in the manner and on the terms described in the Pricing Disclosure Package or to
enforce contracts for the sale of securities; or (iv) in the judgment of the Representative, there shall have occurred any Material Adverse Change. Any termination pursuant to this Section 10 shall be without liability on the part of
(i) the Obligors to any Initial Purchaser, except that the Obligors shall be obligated to reimburse the expenses of Initial Purchasers pursuant to Sections 4 and 6 hereof, (ii) any Initial Purchaser to the Obligors, or (iii) any
party hereto to any other party except that the provisions of Sections 8, 9 and 16 hereof shall at all times be effective and shall survive such termination. 

  
 31 








 SECTION 11. Representations and Indemnities to Survive Delivery. The respective
indemnities, agreements, representations and warranties of the Obligors and the several Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of
any Initial Purchaser (including any of its affiliates), the Obligors or any of their partners, officers or directors or any controlling person, as the case may be, and will survive delivery of and payment for the Securities sold hereunder and any
termination of this Agreement.

 Any party hereto may change the address or facsimile number for receipt of communications by

 SECTION 13. Successors. This Agreement will inure to the benefit of and be binding
upon the parties hereto, and to the benefit of the indemnified parties referred to in Sections 8 and 9 hereof, and in each case their respective successors, and no other person will have any right or obligation hereunder. The term
“successors” shall not include any Subsequent Purchaser or other purchaser of the Securities as such from any of the Initial Purchasers merely by reason of such purchase. 

SECTION 14. Authority of the Representative. Any action by the Initial Purchasers hereunder may be taken by Merrill Lynch on
behalf of the Initial Purchasers, and any such action taken by Merrill Lynch shall be binding upon the Initial Purchasers. 

SECTION 15. Partial Unenforceability. The invalidity or unenforceability of any section, paragraph or provision of this
Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is for any reason determined to be invalid or unenforceable, there shall be
deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable. 

SECTION 16. Governing Law Provisions. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE ARISING UNDER OR RELATED TO THIS
AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF. Any legal suit, action
or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States of America located in the City and County of New
York or the courts of the State of New York in each case located in the City and County of New York (collectively, the “Specified Courts”), and each party hereto irrevocably submits to the exclusive jurisdiction (except for suits,
actions, or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding , as to which such jurisdiction is non-exclusive) of the Specified Courts in any Related Proceeding. Service of any process,
summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the
laying of venue of any Specified Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any Related Proceeding brought in any Specified Court has been brought in an
inconvenient forum. 
 SECTION 17. Default of One or More of the Several Initial Purchasers. If any one or more of the several
Initial Purchasers shall fail or refuse to purchase Securities that it or they have agreed to purchase hereunder on the Closing Date, and the aggregate number of Securities that such defaulting Initial Purchaser or Initial Purchasers agreed but
failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Securities to be purchased on such date, the other Initial Purchasers shall be obligated, severally, in the 


  
 33 








 
proportions that the principal amount of Securities set forth opposite their respective names on Schedule A bears to the aggregate principal amount of Securities set forth opposite the
names of all such non-defaulting Initial Purchasers, or in such other proportions as may be specified by the Initial Purchasers with the consent of the non-defaulting Initial Purchasers, to purchase the principal amount of Securities that such
defaulting Initial Purchaser or Initial Purchasers agreed but failed or refused to purchase on the Closing Date. If any one or more of the Initial Purchasers shall fail or refuse to purchase Securities and the principal amount of Securities with
respect to which such default occurs exceeds 10% of the aggregate principal amount of Securities to be purchased on the Closing Date, and arrangements satisfactory to the Initial Purchasers and the Partnership for the purchase of such Securities are
not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8, 9 and 16 hereof shall at all times be effective and shall survive such
termination. In any such case either the Initial Purchasers or the Partnership shall have the right to postpone the Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Final
Offering Memorandum or any other documents or arrangements may be effected. 
 As used in this Agreement, the term “Initial
Purchaser” shall be deemed to include any person substituted for a defaulting Initial Purchaser under this Section 17. Any action taken under this Section 17 shall not relieve any defaulting Initial Purchaser from liability in
respect of any default of such Initial Purchaser under this Agreement. 
 SECTION 18. No Advisory or Fiduciary
Responsibility. Each of the Obligors acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and

principal and is not the agent or fiduciary of the Obligors or their respective Affiliates, equityholders, creditors or employees or any other party; (iii) no Initial Purchaser has assumed or will assume an advisory or fiduciary responsibility
in favor of the Obligors with respect to any of the transactions contemplated hereby or the process leading thereto (irrespective of whether such Initial Purchaser has advised or is currently advising the Obligors on other matters) or any other
obligation to the Obligors except the obligations expressly set forth in this Agreement; (iv) the several Initial Purchasers and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from
those of the Obligors, and the several Initial Purchasers have no obligation to disclose any of such interests by virtue of any fiduciary or advisory relationship; and (v) the Initial Purchasers have not provided any legal, accounting,

and sale of the Initial Securities occurring today and the application of proceeds therefrom as described in the Disclosure Package and 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. 
 In addition, we have participated in conferences with officers and other
representatives of the Obligors, the independent registered public accounting firm for the Obligors, your counsel and your representatives at which the contents of the Disclosure Package and the Offering Memorandum (including the Incorporated
Documents) 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 or incorporated by
reference in the Disclosure Package 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 with respect to factual matters to the extent we deem appropriate upon
statements by officers and other representatives of the Obligors), no facts have come to our attention that have led us to believe that (i) the Disclosure Package (including the Incorporated Documents), as of
[            ] p.m. (Eastern Time) on July 29, 2014 (which you have informed us is a time prior to the time of the first sale of the Initial Securities by the Initial Purchasers),
contained an untrue statement of a material fact or omitted to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, or (ii) the Offering Memorandum
(including the Incorporated Documents), 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 light of the
circumstances under which they were made, not misleading, it being understood that we did not participate in the preparation of the Incorporated Documents and that we express no opinion, statement or belief in this letter with respect to
(i) the historical and pro forma financial statements and related schedules, including the notes and schedules thereto and the auditors’ reports thereon and (ii) any other financial or accounting data, included or incorporated or
deemed incorporated by reference in, or excluded from, the Offering Memorandum. 
 We express no opinion as to the laws of any jurisdiction
other than (i) applicable laws of the State of New York, (ii) applicable laws of the United States of America, (iii) certain other specified laws of the United States of America to the extent referred to specifically herein,
(iv) the General Corporation Law of the State of Delaware, (v) the Limited Liability Company Act of the State of Delaware and (vi) the Revised Uniform Limited Partnership Act of the State of Delaware. References herein to
“applicable laws” mean those laws, rules and regulations that, in our experience, are normally applicable to transactions of the type contemplated by the Transaction Documents, without our having made any special investigation as to the
applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided however, that such references (including without limitation those
appearing in paragraphs 4 and 5 above) do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, securities, tax, insurance or antitrust, laws, rules or regulations.

 Our opinions expressed herein are subject to the following additional assumptions and
qualifications: 
 (i) The opinions set forth in paragraph 1 above as to the valid existence and good standing of the
entities mentioned in such paragraph are based solely upon our review of certificates and other communications from the appropriate public officials. 

(ii) In rendering the opinions set forth in paragraph 4 above regarding Applicable Agreements, we do not express any opinion,
however, as to whether the execution or delivery by any of the Obligors of any of the Transaction Documents, or the incurrence or performance by any of the Obligors of its obligations thereunder, will constitute a violation of, or a default under or
as a result of, any covenant, restriction or provision with respect to any financial ratio or test or any aspect of the financial condition or results of operation of any of the Obligors. 

(iii) The opinion set forth in paragraph 7 above with respect to United States federal income tax consequences is based upon
our interpretations of current U.S. federal income tax law, including court authority and existing final and temporary United States Treasury regulations, which are subject to change both prospectively and retroactively, and upon the assumptions and
qualifications discussed herein. We note that such opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusion. Such opinion is not binding upon the Internal Revenue Service or courts,
and there is no guarantee that the Internal Revenue Service will not successfully challenge our conclusions. No assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, would
not adversely affect the accuracy of our conclusions. 
 (iv) Our opinions in paragraphs 8, 9, 10, 11, 12 and 13 above may
be: 
 (1) limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or transfer or
other similar laws relating to or affecting the rights of creditors generally; and 
 (2) subject to the application of
general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy and concepts of
materiality, reasonableness, good faith and fair dealing.

 (v) Our opinions in paragraphs 8, 9, 10, 11, 12 and 13 insofar as they
pertain to the choice of law provisions of the instruments referred to in such paragraphs, are rendered solely in reliance upon New York General Obligations Law Section 5-1401, and are expressly conditioned upon the assumption that the
legality, validity, binding effect and enforceability of said provisions will be determined by a court of the State of New York or a United States federal court sitting in New York and applying New York choice of law rules, including said Section 5-1401. We express no opinion as to any such provision if such legality, validity, binding effect or enforceability is determined by any other court, and we call your attention to the decision of the
United States District Court for the Southern District of New York in Lehman Brothers Commercial Corp. v. Minmetals Int’l Non-Ferrous Metals Trading Co., 179 F. Supp. 2d 119 (S.D.N.Y. 2000), which, among other things, contains dicta
relating to possible constitutional limitations upon said Section 5-1401. We express no opinion as to any such constitutional limitations upon said Section 5-1401 or their effect, if any, upon any opinion herein expressed. 

(vi) We express no opinion as to the validity, effect or enforceability of any provisions: 

(1) purporting to establish evidentiary standards or limitations periods for suits or proceedings to enforce such documents or
otherwise, to establish certain determinations (including determinations of contracting parties and judgments of courts) as conclusive or conclusive absent manifest error, to commit the same to the discretion of any Person or permit any Person to
act in its sole judgment or to waive rights to notice; 
 (2) providing that the assertion or employment of any right or
remedy shall not prevent the concurrent assertion or employment of any other right or remedy, or that each and every remedy shall be cumulative and in addition to every other remedy or that any delay or omission to exercise any right or remedy shall
not impair any other right or remedy or constitute a waiver thereof; 
 (3) relating to severability or separability; 

(4) purporting to limit the liability of, or to exculpate, any Person, including without limitation any provision that purports
to waive liability for violation of securities laws; 
 (5) purporting to waive damages; 

(6) that constitute an agreement to agree in the future on any matter;

 (7) that relate to indemnification, contribution or reimbursement obligations
to the extent any such provisions (i) would purport to require any Person to provide indemnification, contribution or reimbursement in respect of the negligence, recklessness, willful misconduct or unlawful behavior of any Person,
(ii) violate any law, rule or regulation (including any federal or state securities law, rule or regulation) or (iii) are determined to be contrary to public policy; 

(8) purporting to establish any obligation of any party as absolute or unconditional regardless of the occurrence or
non-occurrence or existence or non-existence of any event or other state of facts; 
 (9) purporting to obligate any party to
conform to a standard that may not be objectively determinable or employing items that are vague or have no commonly accepted meaning in the context in which used; 

(10) purporting to require the payment of liquidated damages or additional interest for failure timely to comply with
obligations under the Registration Rights Agreement; 
 (11) purporting to require that all amendments, waivers and
terminations be in writing or the disregard of any course of dealing or usage of trade; 
 (12) relating to consent to
jurisdiction insofar as such provisions purport to confer subject matter jurisdiction upon any court that does not have such jurisdiction, whether in respect of bringing suit, enforcement of judgments or otherwise; 

(13) purporting to limit the obligations of any party to the extent necessary to avoid such obligations constituting a
fraudulent transfer or conveyance; 
 (14) purporting to require disregard of mandatory choice of law principles that could
require application of a law other than the law expressly chosen to govern the instrument in which such provisions appear; or 

(15) purporting to waive rights to trial by jury or rights to object to jurisdiction based on inconvenient forum. 

(vii) In making our examination of executed documents, we have assumed (except to the extent that we expressly opine above)
(1) the valid existence and good standing of each of the parties thereto, (2) that such parties had the power and authority,

corporate, partnership, limited liability company or other, to enter into and to incur and perform all their obligations thereunder, (3) the due authorization by all requisite action,
corporate, partnership, limited liability company or other, and the due execution and delivery by such parties of such documents and (4) to the extent such documents purport to constitute agreements, that each of such documents constitutes the
legal, valid and binding obligation of each party thereto, enforceable against such party in accordance with its terms. In this paragraph (vii), all references to parties to documents shall be deemed to mean and include each of such parties, and
each other person (if any) directly or indirectly acting on its behalf. 
 (viii) Except to the extent that we expressly
opine above, we have assumed that the execution and delivery of the Transaction Documents, and the incurrence and performance of the obligations thereunder of the parties thereto do not and will not contravene, breach, violate or constitute a
default under (with the giving of notice, the passage of time or otherwise) (a) the certificate or articles of incorporation, certificate of formation, articles of organization, certificate of limited partnership, charter, bylaws, limited
liability company agreement, regulations, limited partnership agreement or similar organic document of any such party, (b) any contract, indenture, mortgage, loan agreement, note, lease or other agreement or instrument, (c) any statute,
law, rule, or regulation, (d) any judicial or administrative order or decree of any governmental authority, or (e) any consent, approval, license, authorization or validation of, or filing, recording or registration with, any governmental

each such party, other than the Obligors, with all laws, rules and regulations applicable to it, as well as the compliance by the each of the Obligors, and each other person (if any) directly or indirectly acting on its behalf, with all laws, rules
and regulations that may be applicable to it by virtue of the particular nature of the business conducted by it or any goods or services produced or rendered by it or property owned, operated or leased by it, or any other facts pertaining
specifically to it. In this paragraph (viii), all references to parties to the Transaction Documents, other than the first such reference, shall be deemed to mean and include each of such parties, and each other person (if any) directly or
indirectly acting on its behalf. 
 (ix) Without limiting the generality of our qualification in clause (1) of paragraph
(iv) above, we express no opinion as to the applicability or effect of any preference, fraudulent transfer or conveyance, or similar law (including, without limitation, Section 548 of Title 11 of the United States Code or Article 10 of the
New York Debtor Creditor Law) on the Transaction Documents or any transactions contemplated thereby or any opinion expressed herein.

Section [7.07(a)] of the Indenture.

Exchange Security is located (other than the State of New York) that limit the interest, fees or other charges such holder may impose for the loan or use of money or other credit.

notice to or registration, recording or filing with any court, governmental authority or regulatory body (other than routine informational filings, filings under the Securities Act and filings under the Securities Exchange Act of 1934, as amended)
is required to authorize, or is required in connection with the transactions contemplated by the Transaction Documents, the execution or delivery thereof by or on behalf of any party thereto or the incurrence or performance by any of the parties
thereto of its obligations thereunder. 
 (xiv) We express no opinion as to provisions of the Transaction Documents to the
effect that a guarantor is liable as a primary obligor, and not as a surety. We advise you that certain of the guaranty and surety waivers contained in the Indenture may be unenforceable in whole or in part. 

(xv) We have assumed that the sale of Initial Securities pursuant to Regulation S under the Securities Act is not a part
of a plan or scheme to evade the registration provisions of the Securities Act.

  (the “Partnership”) and Compressco Finance Inc. (the “Co-Issuer”). 

Ladies and Gentlemen: 
 I am General Counsel of
Compressco Partners GP Inc., a Delaware corporation and the general partner of the Partnership (the “General Partner”), and in such capacity, I have acted as internal counsel to the Partnership and its subsidiaries in connection
with the Purchase Agreement dated July 29, 2014 (the “Purchase Agreement”) among (i) the Issuer, (ii) the Co-Issuer, (iii) the other subsidiaries of the Issuer named therein as parties thereto and
(iv) Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representative of the several initial purchasers named therein (collectively, the “Initial Purchasers”), relating to the sale by the Partnership and the
Co-Issuer to the Initial Purchasers of $350,000,000 aggregate principal amount of 7.25% Senior Notes due 2022 (the “Initial Securities”) issued jointly by the Partnership and the Co-Issuer. The Initial Securities are being
issued under an Indenture dated as of [August 4, 2014] among the Partnership, the Co-Issuer, the subsidiaries of the Partnership named therein as parties thereto and as guarantors of the Initial Securities (collectively, the
“Guarantors”) and U.S. Bank National Association, as trustee. The Partnership and the Co-Issuer are referred to collectively herein as the “Issuers.” 

I am furnishing this letter to you pursuant to Section 5(c)(ii) of the Purchase Agreement. 

In rendering the statements set forth herein, I have examined and relied on originals or copies, certified or otherwise identified to my
satisfaction, of the following: 
 (a) the Issuers’ Preliminary Offering Memorandum dated July 21, 2014 (the “Preliminary
Offering Memorandum”) relating to the Initial Securities; 
 (b) the Issuers’ Offering Memorandum dated July 29, 2014 (the
“Offering Memorandum”) relating to the Initial Securities; 

  
 Exhibit A-2 - Page 1 









 (c) the Issuers’ pricing term sheet dated July 29, 2014 (the “Pricing Term
Sheet”), relating to the Initial Securities (such Pricing Term Sheet, together with the Preliminary Offering Memorandum, being referred to herein as the “Disclosure Package”); 

(d) each of the Partnership’s reports that have been filed with the Securities and Exchange Commission and are incorporated by reference
in the Offering Memorandum (the “Incorporated Documents”); and 
 (e) such other instruments as I have deemed necessary in
light of the statements expressed herein. 
 Based upon the foregoing and subject to the limitations, qualifications, exceptions and
assumptions set forth herein, I advise you that except as disclosed in the Disclosure Package and the Offering Memorandum (including the Incorporated Documents), I am not aware of any action, suit or legal proceeding pending or overtly threatened
(by written notice to the General Partner or either of the Issuers) against or affecting the Partnership or any of its subsidiaries or any of their respective properties, that, if determined adversely to the Partnership or any of its subsidiaries,
would individually or in the aggregate have a material adverse effect on the business, financial condition, properties or results of operations of the Partnership and its subsidiaries on a consolidated basis. 

This letter is being furnished only to you in connection with the sale of the Initial Securities under the Purchase Agreement occurring today
and is solely for your benefit and is not to be used, circulated, quoted or otherwise referred to for any other purpose or relied upon by any other person or entity, including any purchaser of any Initial Security from you and any subsequent
purchaser of any Initial Security or security issued in exchange therefor, without my express written permission. Statements in this letter as to my awareness of any matter have been made after such internal inquiry posed to the Partnership’s
management as I deemed appropriate, and such statements do not indicate any external investigation of the existence or non-existence of any facts or circumstances. The statements expressed herein are as of the date hereof only and are based on facts
as of such date, and I disclaim any obligation to update this letter after such date or to advise you of changes of facts stated or assumed herein. 

Very truly yours,

 ANNEX II 

Resale Pursuant to Regulation S or Rule 144A. Each Initial Purchaser understands that: 

Such Initial Purchaser agrees that it has not offered or sold and will not offer or sell the Securities in the United States or to, or for the
benefit or account of, a U.S. person (other than a distributor), in each case, as defined in Rule 902 of Regulation S (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the
commencement of the offering of the Securities pursuant hereto and the Closing Date, other than in accordance with Regulation S or another exemption from the registration requirements of the Securities Act. Such Initial Purchaser agrees that,
during such 40-day restricted period, it will not cause any advertisement with respect to the Securities (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any public place and will not
issue any circular relating to the Securities, except such advertisements as are permitted by and include the statements required by Regulation S. 

Such Initial Purchaser agrees that, at or prior to confirmation of a sale of Securities by it to any distributor, dealer or person receiving a
selling concession, fee or other remuneration during the 40-day restricted period referred to in Rule 903 of Regulation S, it will send to such distributor, dealer or person receiving a selling concession, fee or other remuneration a
confirmation or notice to substantially the following effect: 
 “The Securities covered hereby have not been registered under the U.S.
Securities Act of 1933, as amended (the “Securities Act”), and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of your distribution at any time or
(ii) otherwise until 40 days after the later of the date the Securities were first offered to persons other than distributors in reliance upon Regulation S and the Closing Date, except in either case in accordance with Regulation S under
the Securities Act (or in accordance with Rule 144A under the Securities Act or to accredited investors in transactions that are exempt from the registration requirements of the Securities Act), and in connection with any subsequent sale by you
of the Securities covered hereby in reliance on Regulation S under the Securities Act during the period referred to above to any distributor, dealer or person receiving a selling concession, fee or other remuneration, you must deliver a notice
to substantially the foregoing effect. Terms used above have the meanings assigned to them in Regulation S under the Securities Act.” 

Such Initial Purchaser agrees that the Securities offered and sold in reliance on Regulation S will be represented upon issuance by a global
security that may not be exchanged for definitive securities until the expiration of the 40-day restricted period referred to in Rule 903 of Regulation S and only upon certification of beneficial ownership of such Securities by non-U.S. persons or
U.S. persons who purchased such Securities in transactions that were exempt from the registration requirements of the Securities Act.
