26

(b)                                 Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Partnership Parties, their respective directors, officers and employees and each person, if any who controls any Partnership Party within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which such Partnership Parties, director, officer, employee or controlling Person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto or any Marketing Materials, or arise out of or are based upon the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any amendment or supplement thereto, any Written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto or any Marketing Materials a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in 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 Registration Statement, any Preliminary Prospectus, the Pricing Prospectus or the Prospectus or any amendment or supplement thereto, any Written Testing-the-Waters Communication, any Issuer Free Writing Prospectus or any amendment thereof or supplement thereto or any Marketing Materials, in reliance upon and in conformity with written information furnished to the Partnership by such Underwriter through the Representatives expressly for use therein; and will reimburse the Partnership Parties for any legal or other expenses reasonably incurred by the Partnership Parties in connection with investigating or defending any such action or claim as such expenses are incurred.

(c)                                  Promptly after receipt by an indemnified party under Sections 9(a) or 9(b) above  of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such Section, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability it may have to any indemnified party under such Section, except to the extent that the indemnifying party suffers actual prejudice as a result of such failure and shall not relieve the indemnifying party from any liability it may have other than under such Section.  In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party.  After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such Section for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 9 if (i) the indemnified party and

27

the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees or controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees, or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party.  No indemnifying party shall, (x) without the written consent of the indemnified party (which consent shall not be unreasonably withheld), effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.  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 third sentence of this Section 9(c), then the indemnifying party agrees that it shall be liable for any settlement of any such 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 fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle.

(d)                                 If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under this Section 9 in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, from the offering of the Units.  If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits referred to in the immediately preceding sentence, but also the relative fault of the Partnership Parties, on the one hand, and the Underwriters, on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, shall be deemed to

28

be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus.  The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties, on the one hand, or the Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  Each of the Partnership Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9(d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 9(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9(d), each affiliate of an Underwriter and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director and officer of the Partnership Parties, and each person, if any, who controls the Partnership Parties within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Partnership Parties.  The Underwriters’ obligations in this Section 9(d) to contribute are several in proportion to their respective underwriting obligations and not joint.

10.                               Underwriters.

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

29

Agreement shall include any person substituted under this Section 10 with like effect as if such person had originally been a party to this Agreement with respect to such Units.

(b)                                 If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by you and the Partnership as provided in Section 10(a) above, the aggregate number of such Units which remains unpurchased does not exceed one eleventh of the aggregate number of all the Units to be purchased at such Time of Delivery, then the Partnership shall have the right to require each non defaulting Underwriter to purchase the number of Units which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non defaulting Underwriter to purchase its pro rata share (based on the number of Units which such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)                                  If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by you and the Partnership as provided in Section 10(a) above, the aggregate number of such Units which remains unpurchased exceeds one eleventh of the aggregate number of all the Units to be purchased at such Time of Delivery, or if the Partnership shall not exercise the right described in Section 10(b) above to require non defaulting Underwriters to purchase Units of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Partnership to sell the Optional Units) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Partnership, except for the expenses to be borne by the Partnership and the Underwriters as provided in Sections 7 and 12 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11.                               The respective indemnities, agreements, representations, warranties and other statements of the Partnership and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Partnership, or any officer or director or controlling person of the Partnership, and shall survive delivery of and payment for the Units.

12.                               If this Agreement shall be terminated pursuant to Section 8(f) or Section 10 hereof, the Partnership shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, any Units are not delivered by or on behalf of the Partnership as provided herein, the Partnership will reimburse the Underwriters through you for all out of pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Units not so delivered, but the Partnership shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

30

13.                               In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly.

All statements, requests, notices and agreements hereunder shall be in writing and, if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives in care of Barclays Capital Inc., 745 7th Avenue, New York, New York  10019, Attention: Office of the General Counsel; and if to the Partnership shall be delivered or sent by mail, telex or facsimile transmission to the address of the Partnership set forth in the Registration Statement, Attention: J. Gregory Holloway; provided, however, that notices under Section 9(c) shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Partnership by you upon request; provided, however, that notices under Section 5(f) shall be in writing, and, if to the Underwriters, shall be delivered or sent by mail, telex or facsimile transmission to you as the Representatives in care of Barclays Capital Inc., 745 7th Avenue, New York, New York  10019, Attention: Office of the General Counsel.  Any such statements, requests, notices or agreements shall take effect upon receipt thereof.  In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Partnership, which information may include the name and address of their respective clients, as well as other information that will allow  the Underwriters to properly identify their respective clients.

14.                               This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Partnership Parties and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the General Partner, any affiliate of any Underwriter and each person who controls the Partnership or any Underwriter or affiliate of any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement.

Re:                             USA Compression Partners, LP - Lock-Up Letter

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) on behalf of the several Underwriters named in Schedule I to such agreement (collectively, the “Underwriters”), with USA Compression Partners, LP (the “Partnership”), USA Compression GP, LLC, USA Compression Partners, LLC and USAC Leasing, LLC, providing for a public offering of common units representing limited partner interests (the “Units”), in the Partnership pursuant to a Registration Statement on Form S-1 filed with the Securities and Exchange Commission (the “Commission”).

In consideration of the agreement by the Underwriters to offer and sell the Units, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not, directly or indirectly, (1) offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise hedge or dispose of (or enter into any transaction or device that is designed to, or could reasonably be expected to, result in the disposition at any time in the future of) any Common Units (as defined in the partnership agreement of the Partnership, as the same may be amended or restated at or prior to the First Time of Delivery, as defined in the Underwriting Agreement), or any securities of the Partnership that are substantially similar to the Common Units, including,

Exhibit A - 1

but not limited to, any options or warrants to purchase any Common Units, or any securities that are convertible into or exchangeable for, or that represent the right to receive, Common Units or any such substantially similar securities, whether now owned or hereinafter acquired, owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the Commission (collectively the “Undersigned’s Units”), (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of any Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Common Units or securities convertible into or exercisable or exchangeable for Common Units or any other securities of the Partnership, or (4) publicly disclose the intention to do any of the foregoing. The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Units even if the Undersigned’s Units would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Units or with respect to any security that includes, relates to, or derives any significant part of its value from the Undersigned’s Units.

The initial Lock-Up Period will commence on the date of this Lock-Up Letter and continue for 180 days after the public offering date set forth on the final prospectus used to sell the Units (the “Public Offering Date”) pursuant to the Underwriting Agreement.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Units (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iii) with the prior written consent of the Representatives on behalf of the Underwriters; provided, however, that in the case of (i) or (ii), any such transfer shall not involve a disposition for value and no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) shall be required or shall be voluntarily made in connection with such transfer other than a filing on Form 5 of the Exchange Act.  For purposes of this Lock-Up Letter, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin.  The undersigned also agrees and consents to the entry of stop transfer instructions with the Partnership’s transfer agent and registrar against the transfer of the Undersigned’s Units except in compliance with the foregoing restrictions.

It is understood that, if the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Units, the undersigned shall be automatically released from the obligations under this Lock-up Letter Agreement.

The undersigned understands that the Partnership and the Underwriters are relying upon this Lock-Up Letter in proceeding toward consummation of the offering.  The undersigned further understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

Re:                             USA Compression Partners, LP

Ladies and Gentlemen:

We have acted as special Delaware counsel for USA Compression Partners, LP, a Delaware limited partnership (the “Partnership”), USA Compression GP, LLC (formerly known as R/C IV USA Compression Partners GP, LLC), a Delaware limited liability company (the “General Partner”), USA Compression Partners, LLC, a Delaware limited liability company (the “Operating Company”), and USAC Leasing, LLC, a Delaware limited liability company (“Leasing”), in connection with the matters set forth herein.  At your request, this opinion is being furnished to you.

For purposes of giving the opinions hereinafter set forth, our examination of documents has been limited to the examination of executed or conformed counterparts, or copies otherwise proved to our satisfaction, of the following:

1.                                      The First Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of                  , 2013 (the “Partnership Agreement”), among the General Partner, USA Compression Holdings, LLC, a Delaware limited liability company (“Holdings”), and the other Persons who become Partners in the Partnership or parties thereto as provided therein;

2.                                      The Second Amended and Restated Limited Liability Company Agreement of the General Partner, dated as of                , 2013 (the “GP Agreement”), by Holdings, as the sole member (the “GP Member”);

3.                                      The Amended and Restated Limited Liability Company Agreement of the Operating Company, dated as of December 23, 2010 (the “Operating Company Agreement”), by the Partnership, as the sole member (the “Operating Company Member”), and the General Partner, as the manager (the “Operating Company Manager”); and

4.                                      The Amended and Restated Limited Liability Company Agreement of Leasing, dated as of December 23, 2010 (the “Leasing Agreement”), by the Operating Company, as the sole member (the “Leasing Member”), and the General Partner, as the manager (the “Leasing Manager”).

The General Partner, the Operating Company and Leasing are hereinafter referred to each as a “Company”, and collectively as the “Companies”.  The General Partner Agreement, the Operating Company Agreement and the Leasing Agreement are hereinafter referred to each as an “LLC Agreement”, and collectively as the “LLC Agreements”.

For purposes of this opinion, we have not reviewed any documents other than the documents listed in paragraphs (a) through (d) above.  In particular, we have not reviewed any document (other than the documents listed in paragraphs (a) through (d) above) that is referred to in or incorporated by reference into any document reviewed by us.  We have assumed that there exists no provision in any document that we have not reviewed that is inconsistent with the opinions stated herein.  We have conducted no independent factual investigation of our own, but rather have relied solely upon the foregoing documents, the statements and information set forth therein and the additional matters recited or assumed herein, all of which we have assumed to be true, complete and accurate in all material respects.

With respect to all documents examined by us, we have assumed that (i) all signatures on documents examined by us are genuine, (ii) all documents submitted to us as originals are authentic, and (iii) all documents submitted to us as copies conform with the originals of those documents.

For purposes of this opinion, we have assumed (1) that the Partnership Agreement constitutes the entire agreement among the parties thereto with respect to the subject matter thereof, including with respect to the admission of partners to, and the formation, operation and termination of, the Partnership, and that the Partnership Agreement is in full force and effect, has not been amended and no amendment of such document is pending or has been proposed, (2) that each LLC Agreement constitutes the entire agreement among the parties thereto with respect to the subject matter thereof, including with respect to the admission of members to, and the formation, operation and termination of, the applicable Company, and that each LLC Agreement is in full force and effect has not been amended and no amendment of such document is pending or has been proposed, (3) that any amendment or restatement of any document reviewed by us has been accomplished in accordance with, and was permitted by, the relevant provisions of such document prior to its amendment or restatement from time to time, (4) that there are no proceedings pending or contemplated for the merger, consolidation, conversion, dissolution, liquidation or termination of the Partnership or any Company, (5) that each party to the documents examined by us, and the Partnership and each Company, has been duly created, organized or formed, as the case may be, and is validly existing in good standing under the laws of the jurisdiction governing its creation, organization or formation, (6) the legal capacity of natural persons who are signatories to the documents examined by us, (7) that each of the parties to the documents examined by us has the power and authority to execute and deliver, and to perform its obligations under, such documents, and (8) that each of the parties to the documents examined by us has duly authorized, executed and delivered such documents.  We have not participated in the preparation of any offering material relating to the Partnership or any of the Companies and assume no responsibility for the contents of any such material.

This opinion is limited to the laws of the State of Delaware (excluding the securities laws and blue sky laws of the State of Delaware), and we have not considered and express no opinion on the laws of any other jurisdiction, including federal laws and rules and

regulations relating thereto.  Our opinions are rendered only with respect to Delaware laws and rules, regulations and orders thereunder that are currently in effect.  In rendering the opinions set forth herein, we express no opinion concerning (i) the creation, attachment, perfection or priority of any security interest, lien or other encumbrance, or (ii) the nature or validity of title to any property.

Based upon the foregoing, and upon our examination of such questions of law and statutes of the State of Delaware as we have considered necessary or appropriate, and subject to the assumptions, qualifications, limitations and exceptions set forth herein, we are of the opinion that:

(a)                                 The Partnership Agreement constitutes a valid and binding agreement of the General Partner, and is enforceable against the General Partner, in accordance with its terms.

(b)                                 The GP Agreement constitutes a valid and binding agreement of the GP Member, and is enforceable against the GP Member, in accordance with its terms.

(c)                                  The Operating Company Agreement constitutes a valid and binding agreement of the Operating Company Member and the Operating Company Manager, and is enforceable against the Operating Company Member and the Operating Company Manager, in accordance with its terms.

(d)                                 The Leasing Agreement constitutes a valid and binding agreement of the Leasing Member and the Leasing Manager, and is enforceable against the Leasing Member and the Leasing Manager, in accordance with its terms.

The opinions expressed above are subject to the effect upon the Partnership Agreement and each LLC Agreement, of (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.

In rendering the opinions expressed above, we express no opinion with respect to (i) provisions of a document reviewed by us to the extent that such provisions purport to bind a person or entity that is not a party to such document, and (ii) any provision of a document reviewed by us to the effect that the failure to exercise or delay in exercising rights or remedies will not impair or operate as a waiver of such rights or remedies.  In connection with the opinions rendered in paragraphs 3 and 4 above, we note that with respect to Sections 20(a) and (b) of the LLC Agreement of each of the Operating Company and Leasing, under the Delaware Limited Liability Company Act (6 Del. C. § 18-101 et seq.), (i) the existence of the applicable Company as a separate legal entity shall continue, and such Company will not terminate under the LLC Act, until a certificate of cancellation of the certificate of formation of such Company is filed with the Secretary of State of the State of Delaware and becomes effective, and (ii) the

winding up of the affairs of such Company is required to be completed prior to the termination of such Company.

We understand that you will rely as to matters of Delaware law upon this opinion in connection with the matters set forth herein.  In connection with the foregoing, we hereby consent to your relying as to matters of Delaware law upon this opinion, subject to the understanding that the opinions herein are given on the date hereof and such opinions are rendered only with respect to facts existing on the date hereof and laws and rules, regulations and orders thereunder in effect as of such date.  Except as stated above, without our prior written consent, this opinion may not be furnished or quoted to, or relied upon by, any other person or entity for any purpose.
