Ladies and Gentlemen:

Each of USA Compression Partners, LP, a Delaware limited partnership (the “Partnership”), and USA Compression GP, LLC, a Delaware limited liability company and the general partner of the Partnership (the “General Partner”), confirms its agreement (this “Agreement”) with UBS Securities LLC, Raymond James & Associates, Inc., RBC Capital Markets, LLC and SunTrust Robinson Humphrey, Inc. (the “Managers”), as follows:

SECTION 1. Description of Securities. The Partnership proposes to issue and sell through or to one or more of the Managers, as sales agents and/or principals, common units representing limited partner interests in the Partnership (the “Common Units”), having an aggregate gross sales amount of up to $150,000,000 (the “Units”) on the terms set forth in Section 3 of this Agreement. The Partnership agrees that whenever it determines to sell the Units directly to a Manager as principal, it will enter into a separate agreement (each, a “Terms Agreement”), in form and substance satisfactory to the Manager, relating to such sale in accordance with Section 3 of this Agreement.

Each of the General Partner and the Partnership is sometimes referred to herein as a “Partnership Party,” and they are sometimes collectively referred to herein as the “Partnership

Parties.” The entities identified on Schedule B hereto are collectively referred to as the “Operating Subsidiaries.” Each of the Partnership Parties and each of the Operating Subsidiaries are sometimes referred to herein as a “Partnership Entity,” and they are sometimes collectively referred to herein as the “Partnership Entities.”

SECTION 2. Representations and Warranties of the Partnership Parties. The Partnership Parties represent and warrant to and agree with the Managers that:

(a) Registration Statement. A registration statement (the “registration statement”), including a form of prospectus, has been prepared and filed by the Partnership pursuant to the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively called the “Act”), on Form S-3 (File No. 333-193724) in respect of the Units, not earlier than three years prior to the date hereof, in conformity with the requirements of the Act, and the rules and regulations of the Securities and Exchange Commission (the “Commission”) thereunder (the “Rules and Regulations”). The Commission has not issued an order preventing or suspending the use of the Base Prospectus (as defined below), the Prospectus Supplement (as defined below), the Prospectus (as defined below) or any Permitted Free Writing Prospectus (as defined below), or the effectiveness of the Registration Statement (as defined below), and no proceeding for that purpose or pursuant to Section 8A of the Act has been instituted or, to the Partnership’s knowledge, threatened by the Commission. Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the Managers, including (1) all documents filed as a part thereof or incorporated or deemed to be incorporated by reference therein, (2) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430B or Rule 430C under the Act, to be part of the registration statement at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the Managers, and (3) any registration statement filed to register the offer and sale of Common Units pursuant to Rule 462(b) under the Act. Except where the context otherwise requires, “Base Prospectus,” as used herein, means the prospectus filed as part of each Registration Statement, together with any amendments or supplements thereto as of the date of this Agreement. Except where the context otherwise requires, “Prospectus Supplement,” as used herein, means the final prospectus supplement, relating to the Units, filed by the Partnership with the Commission pursuant to Rule 424(b) under the Act on or before the second business day after the date hereof (or such earlier time as may be required under the Act), in the form furnished by the Partnership to the Managers in connection with the offering of the Units. Except where the context otherwise requires, “Prospectus,” as used herein, means the Prospectus Supplement together with the Base Prospectus attached to or used with the Prospectus Supplement. Notwithstanding the foregoing, if any revised base prospectus, prospectus supplement or prospectus shall be provided to the Managers by the Partnership for use in connection with the offering and sale of the Units which differs from the Base Prospectus, Prospectus Supplement or Prospectus, as the case may be (whether or not such revised base prospectus, prospectus supplement or prospectus is required to be filed by the Partnership pursuant to

Rule 424(b) of the Act), the terms “Base Prospectus,” “Prospectus Supplement” and “Prospectus” shall refer to such revised base prospectus, prospectus supplement or prospectus, as the case may be, from and after the time it is first provided to the Managers for such use. “Permitted Free Writing Prospectuses,” as used herein, means the documents listed on Schedule A attached hereto and any other “issuer free writing prospectus” (as defined in Rule 433 of the Act) that the Partnership and the Managers shall agree from time to time is a Permitted Free Writing Prospectus.

SECTION 3. Sale and Delivery of Securities.

(a) On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Partnership agrees to issue and sell through or to one or more of the Managers, as sales agents, and each Manager agrees, severally and not jointly, to use its commercially reasonable efforts to sell, as sales agent for the Partnership, the Units on the following terms.

(i) The Units are to be sold on a daily basis or otherwise as shall be agreed to by the Partnership and any Manager on any day that (A) is a trading day for the

NYSE (a “Trading Day”) (other than a Trading Day on which the NYSE is scheduled to close prior to its regular weekday closing time), (B) the Partnership has instructed the Managers by telephone (confirmed promptly by electronic mail) from any of the individuals listed as authorized representatives of the Partnership on Schedule C hereto (as may be updated by the Partnership from time to time) (the “Authorized Partnership Representatives”) to make such sales and (C) the Partnership Parties have satisfied their obligations under Section 6 of this Agreement. The Partnership shall make sales through only one of the Managers on any given Trading Day. The Partnership will designate the maximum number of Units to be sold by the applicable Manager daily as agreed to by such Manager and in any event not in excess of the amount of Units available for issuance under the currently effective Registration Statement or in excess of the amount of Units authorized from time to time to be issued and sold under this Agreement by the board of directors of the General Partner, or a duly authorized committee thereof, and notified to such Manager in writing. Subject to the terms and conditions hereof, the applicable Manager shall use reasonable efforts to offer and sell all of the Units designated on any day; provided, however, that such Manager shall have no obligation to offer or sell any Units, and the Partnership acknowledges and agrees that such Manager shall have no such obligation, in the event an offer or sale of the Units on behalf of the Partnership may in the judgment of such Manager constitute the sale of a “block” under Rule 10b-18(a)(5) under the Exchange Act or a “distribution” within the meaning of Rule 100 of Regulation M under the Exchange Act or such Manager reasonably believes it may be deemed an “underwriter” under the Act in a transaction that is other than by means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 under the Act (such ordinary brokers’ transactions are hereinafter referred to as “At the Market Offerings”).

(ii) Notwithstanding the foregoing, the Partnership, through any of the Authorized Partnership Representatives, may instruct any Manager by telephone (confirmed promptly by electronic mail) not to sell the Units if such sales cannot be effected at or above the price designated by the Partnership in any such instruction. In addition, the Partnership or any Manager may, upon notice to the other party by telephone (confirmed promptly by electronic mail), suspend the offering of the Units; provided, however, that such suspension shall not affect or impair the parties’ respective obligations with respect to the Units sold hereunder prior to the giving of such notice; provided further, that such suspension by a Manager will not impact the Partnership’s ability to conduct sales of the Units with other Managers pursuant to this Agreement.

(iii) Each Manager hereby covenants and agrees not to make any sales of the Units on behalf of the Partnership, pursuant to this Section 3(a), other than (A) by means of At the Market Offerings and (B) such other sales of the Units on behalf of the Partnership in their capacity as agents of the Partnership as shall be agreed by the Partnership and the Managers.

(iv) The compensation to each Manager, as agent of the Partnership, for sales of the Units shall be up to 2.0% of the gross sales price of the Units sold pursuant to this Section 3(a). The remaining proceeds, after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in

connection with such sales, shall constitute the net proceeds to the Partnership for such Units (the “Net Proceeds”).

(v) Each Manager shall provide written confirmation to the Partnership following the close of trading on the NYSE each day in which the Units are sold under this Section 3(a) by such Manager setting forth the aggregate amount of the Units sold on such day, the aggregate gross sales proceeds, any transactions fees deducted pursuant to Section 3(a)(iv), the Net Proceeds to the Partnership, and the aggregate compensation payable by the Partnership to such Manager with respect to such sales.

(vi) Settlement for sales of the Units pursuant to this Section 3(a) will occur on the third Trading Day following the date on which such sales are made (provided that, if such third Trading Day is not a business day (as defined below), then settlement will occur on the next succeeding Trading Day that is also a business day), unless another date shall be agreed upon by the Partnership and the applicable Manager (each such date, a “Settlement Date”). As used in the preceding sentence and in Section 7 below, the term “business day” means any day other than a Saturday, Sunday or other day on which commercial banks in the City of New York are authorized or required by law, regulation or executive order to close. On each Settlement Date, the Units sold through any Manager for settlement on such date shall be issued and delivered by the Partnership to the applicable Manager against payment of the Net Proceeds for the sale of such Units. Settlement for all such Units shall be effected by free delivery of the Units by the Partnership or its transfer agent to the applicable Manager’s account, or to the account of the applicable Manager’s designee, at The Depository Trust Company (“DTC”), through its Deposit and Withdrawal at Custodian System (“DWAC”) or by such other means of delivery as may be mutually agreed upon by the parties hereto, which in all cases shall be freely tradable, transferable, registered Common Units eligible for delivery through DTC, in return for payments in same day funds delivered to the account designated by the Partnership. If the Partnership, or its transfer agent (if applicable), shall default on its obligation to deliver the Units on any Settlement Date, the Partnership shall (A) indemnify and hold the applicable Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership and (B) pay the applicable Manager any commission to which it would otherwise be entitled absent such default. The Authorized Partnership Representatives shall be the contact persons for the Partnership for all matters related to the settlement of the transfer of the Units through DWAC for purposes of this Section 3(a).

(vii) Subject to the terms of a Terms Agreement, the Managers may sell the Units (i) by any method permitted by law deemed to be an “at the market” offering as defined in Rule 415 of the Act, including without limitation sales made directly on any existing trading market for the Common Units, (ii) to or through a market maker, or (iii) directly on or through an electronic communication network, a “dark pool” or any similar market venue. Subject to the terms of a Terms Agreement, the Managers may also sell the Units by any other method permitted by law, including but not limited to in privately negotiated transactions.

(viii) At each Time of Sale, Settlement Date and Representation Date (as defined in Section 4(q)), the Partnership Parties shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date but modified to incorporate the disclosures contained or incorporated by reference in the Registration Statement and the Prospectus, in each case as amended or supplemented as of such date. Any obligation of any Manager to use its commercially reasonable efforts to sell the Units on behalf of the Partnership shall be subject to the continuing accuracy of the representations and warranties of the Partnership Parties herein, to the performance by the Partnership Parties of their obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

(b) If the Partnership wishes to issue and sell the Units other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Managers of the proposed terms of such Placement. If any Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Partnership, wishes to accept amended terms, such Manager and the Partnership will enter into a Terms Agreement setting forth the terms of such Placement. In the event of a conflict between the terms of this Agreement and the terms of any Terms Agreement, the terms of such Terms Agreement will control.

(c) (i) Under no circumstances shall the Partnership cause or request the offer or sale of any Units if, after giving effect to the sale of such Units, the aggregate gross sales proceeds or the aggregate number of the Units sold pursuant to this Agreement would exceed the lesser of (A) the amount set forth in Section 1, (B) the amount available for offer and sale under the currently effective Registration Statement and (C) the amount authorized from time to time to be issued and sold under this Agreement by the General Partner’s board of directors, or a duly authorized committee thereof, and notified to the Managers in writing. Under no circumstances shall the Partnership cause or request the offer or sale of any Units at a price lower than the minimum price authorized from time to time by the General Partner’s board of directors, or a duly authorized committee thereof, and notified to the Managers in writing.

(ii) If any party hereto has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Units, it shall promptly notify the other party and sales of the Units under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(d) Each sale of the Units to or through any Manager shall be made in accordance with the terms of this Agreement or, if applicable, a Terms Agreement.

(e) Notwithstanding such further limitations on offers and sales of Units or delivery of instructions to offer and sell Units as are set forth herein and as may be mutually agreed upon by the Partnership and any Manager, offers and sales of Units pursuant to this Agreement shall not be requested by the Partnership and need not be

made by any Manager at any time when or during any period in which the Partnership is or could be deemed to be in possession of material non-public information.

(f) The Partnership Parties acknowledge and agree that (A) there can be no assurance that any Manager will be successful in selling the Units, (B) each Manager will incur no liability or obligation to the Partnership or any other person or entity if it does not sell Units for any reason other than a failure by the Manager to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Units in accordance with the terms of this Agreement, and (C) the Manager shall be under no obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed in writing by the Manager and the Partnership.

(ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this Section 7 being deemed to include any Base Prospectus, any Prospectus Supplement, any Prospectus and any amendments or supplements to the foregoing), in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Partnership or in any Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any, or arises out of or is based upon any omission or alleged omission to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except, with respect to such Prospectus or Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning any Manager furnished in writing by or on behalf of any Manager to the Partnership expressly for use in, such Prospectus or Permitted Free Writing Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(b) Each Manager agrees, severally and not jointly, to indemnify, defend and hold harmless the Partnership Parties, their directors, officers and employees, and any person and its affiliates who controls the Partnership Parties within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Partnership Parties or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Manager furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Partnership), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Manager furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, the Prospectus Supplement or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in the Prospectus Supplement or a Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Partnership Parties or any Manager (as applicable, the “indemnifying party”) pursuant to subsection (a) or (b), respectively, of this Section 7(c), such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party or otherwise. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding or the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but, if settled with its written consent, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability, as incurred, by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this Section 7(c), then 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 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have (A) fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement or (B) notified the indemnified party in writing that it is disputing in good faith all or any non-reimbursed portion of the fees in such request stating in reasonable detail the basis for such dispute, and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an

admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d) If the indemnification provided for in this Section 7 is unavailable to an indemnified party under subsections (a) and (b) of this Section 7 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership, on the one hand, and the applicable Manager, on the other hand, from the offering of the Units 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 Partnership Parties, on the one hand, and of the applicable Manager, on the other, in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Partnership Parties, on the one hand, and the applicable Manager, on the other, shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Partnership Parties, and the total underwriting discounts and commissions received by the applicable Manager, bear to the aggregate public offering price of the Units. The relative fault of the Partnership Parties, on the one hand, and of the applicable Manager, on the other, shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Partnership Parties or by the applicable Manager 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, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e) The Partnership Parties and the Managers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (d) above. Notwithstanding the provisions of this Section 7, the Managers shall not be required to contribute any amount in excess of commissions received by them under this Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) The Partnership Parties and the Managers agree promptly to notify each other of the commencement of any Proceeding and, in the case of the Partnership Parties, against any of the Partnership’s officers or directors in connection with the issuance and sale of the Units, or in connection with the Registration Statement, the Base Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

SECTION 8. Representations and Agreements to Survive Delivery. The indemnity and contribution agreements contained in Section 7 and the covenants, warranties and representations of the Partnership Parties contained in this Agreement or in certificates delivered pursuant hereto shall remain in full force and effect regardless of any investigation made by or on behalf any of the Managers or any of their affiliates or their directors, officers, employees or agents or any persons (including each director, officer, employee or agent of such persons) who control any of the Managers within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of either of the Partnership Parties, their directors or officers or any person who controls them within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Units.

(c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 9(a) or (b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that the provisions of Sections 5, 7, 8, 10, 11, 12, 16, 17, 18, 19 and 20 of this Agreement shall remain in full force and effect notwithstanding such termination, except as otherwise explicitly agreed to in such written termination.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Managers or the Partnership Parties, as the case may be.

The Partnership Parties and each Manager agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by each Manager to the Partnership Parties regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Partnership’s securities, do not constitute advice or recommendations to the Partnership Parties. Each Partnership Party and Manager hereby waives and releases, to the fullest extent permitted by law, any claims that such party may have against the other party with respect to any breach or alleged breach of any fiduciary or similar duty to such party in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

SECTION 13. [Intentionally omitted].

SECTION 14. Adjustments for Splits or Combinations. The parties acknowledge and agree that all unit count-related numbers contained in this Agreement shall be adjusted to take into account any split or combination or the like effected with respect to the Common Units.

SECTION 15. Entire Agreement. This Agreement constitutes the entire agreement and supersedes all other prior and contemporaneous agreements and undertakings, both written and oral, among the parties hereto with regard to the subject matter hereof.

SECTION 16. Counterparts. This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

SECTION 17. Law; Construction. This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the internal laws of the State of New York.

SECTION 18. Headings. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

SECTION 19. Submission to Jurisdiction. Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the parties hereto consent to the jurisdiction of such courts and personal service with respect thereto. The parties hereto hereby consent to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against such party or any indemnified party. Each of the parties hereto (on its own behalf and, to the extent permitted by applicable law, on behalf of its equity owners and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The parties hereto agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon each of them and may be enforced in any other courts to the jurisdiction of which the applicable parties are or may be subject, by suit upon such judgment.

SECTION 20. Successors and Assigns. This Agreement shall be binding upon the Managers and the Partnership Parties and their successors and assigns and any successor or assign of any substantial portion of the Partnership’s and the Managers’ respective businesses and/or assets.

SECTION 21. Miscellaneous. Each of UBS Securities LLC, Raymond James & Associates, Inc., RBC Capital Markets, LLC and SunTrust Robinson Humphrey, Inc. is an indirect, wholly owned subsidiary of UBS AG, Raymond James Bank, N.A., Royal Bank of Canada and SunTrust Bank, respectively, and is not a bank and is separate from any affiliated banks, including any U.S. branch or agency of UBS AG, Raymond James Bank, N.A., Royal Bank of Canada and SunTrust Bank, as applicable. Because each of the Managers is a separately organized entity, each Manager is solely responsible for its own contractual obligations and

commitments, including obligations with respect to sales and purchases of securities. Securities sold, offered or recommended by the Managers are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

Exhibit A

FORM OF OPINION AND NEGATIVE ASSURANCE LETTER OF VINSON & ELKINS L.L.P.

1. The Partnership has been duly formed and is validly existing in good standing as a limited partnership under the Delaware LP Act with all requisite limited partnership power and authority to own its properties and to conduct its business as described in the Registration Statement and the Prospectus.

2. The General Partner has been duly formed and is validly existing in good standing as a limited liability company under the Delaware LLC Act with all requisite limited liability company power and authority to own its properties, conduct its business and act as the general partner of the Partnership as described in the Registration Statement and the Prospectus.

3. Each of USA Compression Partners, LLC and USAC Leasing, LLC (together, the “Delaware LLCs”) is validly existing in good standing as a limited liability company under the Delaware LLC Act with all requisite limited liability company power and authority to own its properties and conduct its business as described in the Registration Statement and the Prospectus.

4. Each of USAC OpCo 2, LLC and USAC Leasing 2, LLC (together, the “Texas LLCs”) is validly existing in good standing as a limited liability company under the Texas LLC Act with all requisite limited liability company power and authority to own its properties and conduct its business as described in the Registration Statement and the Prospectus.

5. The Units to be issued and sold by the Partnership pursuant to the Equity Distribution Agreement and the limited partner interests represented thereby have been duly authorized by the Partnership and, when issued by the Partnership against payment therefor as provided in the Equity Distribution Agreement, will be validly issued, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by the matters described in Sections 17-303, 17-607 and 17-804 of the Delaware LP Act).

6. All limited partnership and limited liability company action, as the case may be, required to be taken by either of the Partnership Parties for the authorization, issuance, sale and delivery of the Units and the execution and delivery of the Equity Distribution Agreement has been validly taken.

7. The Equity Distribution Agreement has been duly authorized, executed and delivered by each of the Partnership Parties.

8. Each of the Organizational Documents has been duly authorized, executed and delivered by the Partnership Entities party thereto and are valid and legally binding agreements of

such Partnership Entities party thereto, enforceable against such parties thereto in accordance with their terms; provided, that, with respect to each such agreement, the enforceability thereof may be limited by (i) bankruptcy, insolvency, moratorium, receivership, reorganization, liquidation and other similar laws relating to or affecting the rights and remedies of creditors generally, (ii) principles of equity (regardless of whether considered and applied in a proceeding in equity or at law), (iii) the law of fraudulent transfer and conveyance, (iv) public policy, including the effect of applicable public policy on the enforceability of provisions relating to indemnification, exculpation, contribution, and the waiver or release of statutory, legal or equitable rights, defenses or claims, (v) applicable law relating to fiduciary duties, and (vi) judicial imposition of an implied covenant of good faith and fair dealing.

9. None of the offering, issuance or sale by the Partnership of the Units or the execution, delivery and performance of the Equity Distribution Agreement by the Partnership Parties (i) constitutes or will constitute a violation of the Organizational Documents, (ii) constitutes or will constitute a breach or violation of, or a default under (or an event which, with notice or lapse of time or both, would constitute such a default) or results or will result in the creation or imposition of any Lien upon any property or assets of the Partnership Entities pursuant to, any agreement listed on Annex B attached hereto, (iii) violates or will violate the Delaware LLC Act, the Delaware LP Act, the laws of the State of Texas or federal law, it being understood that we do not express an opinion in clause (iii) of this paragraph 9 with respect to any securities or other anti-fraud law.

10. No permit, consent, approval, authorization, order, registration, filing of or with any federal, New York, Texas or Delaware court or governmental agency or body having jurisdiction over any of the Partnership Entities or any of their respective properties is required in connection with the offering, issuance or sale by the Partnership of the Units or the execution, delivery and performance of the Equity Distribution Agreement by the Partnership Parties except (a) such as may be required under the Act, the Exchange Act, the Blue Sky laws of any jurisdiction or the by-laws and rules of the FINRA, as to which we do not express any opinion, (b) such as have been obtained or made and (c) such as would have a Material Adverse Effect or would reasonably be expected to materially impair the ability of any of the Partnership Parties to consummate the transactions provided for in this Equity Distribution Agreement.

11. The Registration Statement was declared effective under the Act on April 23, 2014; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) under the Act has been made in the manner and within the time period required by such rule.

12. The Registration Statement at its Effective Date and the Prospectus, as of its date (except for the financial statements and the related notes and schedules thereto and the auditor’s report thereon and the other financial and accounting data included or incorporated by reference in or omitted from the Registration Statement or the Prospectus, as to which we do not express any opinion), each appear on their face to be appropriately responsive in

all material respects to the applicable form requirements for registration statements on Form S-3 under the Act and the rules and regulations promulgated thereunder.

13. The Units conform in all material respects to the description thereof contained in each of the Registration Statement and the Prospectus.

14. The statements included or incorporated by reference in the Registration Statement and the Prospectus under the captions “How We Make Cash Distributions,” “Description of Partnership Securities,” “Conflicts of Interest and Fiduciary Duties” and “The Partnership Agreement,” insofar as they purport to describe specific agreements or constitute summaries of certain provisions of federal laws referred to therein, are accurate descriptions or summaries thereof in all material respects.

15. The Partnership is not, and immediately after the sale of the Units to be sold by the Partnership in accordance with the Equity Distribution Agreement and the application of the proceeds as described in the Prospectus under the caption “Use of Proceeds,” will not be required to be registered as, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

16. The General Partner is the sole general partner of the Partnership; the general partner interest has been duly authorized and validly issued in accordance with the Partnership Agreement.

17. The General Partner owns all of the Incentive Distribution Rights; such Incentive Distribution Rights and the limited partner interests represented thereby have been duly authorized and validly issued in accordance with the Partnership Agreement.

18. Except as described in the Registration Statement and the Prospectus or provided for in the Partnership Agreement, there are no preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any limited partner interests in the Partnership pursuant to Delaware law or any agreement or instrument known to such counsel to which any of the Partnership Entities is a party or by which any one of them may be bound. Except as described in the Registration Statement and the Prospectus, to our knowledge there are no outstanding options or warrants to purchase (A) any Common Units, Subordinated Units or other interests in the Partnership or (B) any interest in the General Partner or the Operating Subsidiaries;

19. All of the Common Units, Subordinated Units and Incentive Distribution Rights in the Partnership have been duly authorized and validly issued and are fully paid and nonassessable (except as such nonassessability may be affected by the matters described in Sections 17-303, 17-607 and 17-804 of the Delaware LP Act).

20. The opinion letter of Vinson & Elkins L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Managers may rely upon such opinion letter as if it were addressed to them.

In addition, we have participated in conferences with officers and other representatives of the Partnership Parties and the independent registered public accounting firm of the Partnership,

your counsel and your representatives, at which the contents of the Registration Statement, the Prospectus and related matters were discussed, and although we have not independently verified, are not passing upon, and are not assuming any responsibility for, the accuracy, completeness or fairness of the statements contained in the Registration Statement and the Prospectus (except to the extent specified in the opinions expressed in paragraphs 14 and 15 above), based on the foregoing, no facts have come to our attention that lead us to believe that:

· the Registration Statement, at the time it became effective on April 23, 2014, including the information deemed to be a part of the Registration Statement pursuant to Rule 430B under the Act (together with the documents incorporated by reference at that time) contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or

· the Prospectus (together with the documents incorporated by reference at that time), 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 a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that we express no belief with respect to the financial statements, schedules, or other financial data included in, incorporated in or omitted from, the Registration Statement or the Prospectus.

Exhibit B

OPINION OF IN-HOUSE COUNSEL

1. There is no pending (for which any of the Partnership Entities has been duly served) or, to the knowledge of such counsel, threatened action, suit, proceeding, inquiry or investigation by or before any court or governmental or other regulatory or administrative agency, authority or body or any arbitrator involving any of the Partnership Entities or its or their property of a character required to be disclosed in the Registration Statement which is not so described.

2. To such counsel’s knowledge, there are no contracts or other documents that are required by the Act or the Rules and Regulations to be described in the Registration Statement and the Prospectus or filed as exhibits to the Registration Statement that have not been so described in the Registration Statement and the Prospectus or filed as exhibits to the Registration Statement.
