ARTICLE IV.

REPRESENTATIONS AND WARRANTIES OF EACH PURCHASER

Each Purchaser severally and not jointly, represents and warrants to the Partnership solely with respect to itself as follows as of the date hereof:

Section 4.01 Corporate Existence. Such Purchaser, if such Purchaser is a corporation, limited liability company, partnership, statutory trust or other entity, (i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and (ii) has all requisite power, and has all material governmental licenses, permits, authorizations, consents and approvals necessary to own its assets and carry on its business as its business is now being conducted, except where the failure to obtain such licenses, permits, authorizations, consents and approvals would not have or would not reasonably be expected to have a Purchaser Material Adverse Effect. If Purchaser is an individual, such Purchaser has the authority to enter into, deliver and perform its obligations under this Agreement.

Section 4.02 No Conflicts. The execution, delivery and performance by such Purchaser of the Basic Documents and all other agreements and instruments to be executed and delivered by such Purchaser pursuant to the Basic Documents or in connection therewith, compliance by such Purchaser with the terms and provisions thereof, and the purchase of the Purchased Units by such Purchaser do not and will not (i) conflict with or result in a violation of any provision of the organizational documents of such Purchaser if such Purchaser is a corporation, limited liability company, partnership, statutory trust or other entity, (ii) require any consent (other than standard internal consents), approval or notice under or result in a breach or violation of any of the terms or provisions of, or constitute a default (or give rise to any right of termination, cancellation or acceleration) under (a) any note, bond, mortgage, license, or loan or credit agreement to which such Purchaser is a party or by which such Purchaser or any of its Properties may be bound or (b) any other agreement, instrument or obligation, or (iii) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over such Purchaser or the property or assets of such Purchaser, except in the case of clauses (ii) and (iii), where such conflict, violation, default, breach, termination, cancellation, failure to receive consent or approval, or acceleration with respect to the foregoing provisions of this Section 4.02 would not, individually or in the aggregate, reasonably be likely to have a Purchaser Material Adverse Effect.

Section 4.03 Investment. Such Purchaser represents and warrants to, and covenants and agrees with, the Partnership that the Purchased Units are being acquired for such Purchaser’s own account, not as a nominee or agent, and with no present intention of distributing the Purchased Units or any part thereof, and that such Purchaser has no present intention of selling or granting any participation in or otherwise distributing the same in any transaction in violation of the securities laws of the United States of America or any State, without prejudice, however, to such

20

Purchaser’s right at all times to sell or otherwise dispose of all or any part of the Purchased Units under a registration statement under the Securities Act and applicable state securities laws or under an exemption from such registration available thereunder (including, without limitation, if available, Rule 144 promulgated thereunder). Notwithstanding the foregoing, any Purchaser may at any time transfer Purchased Units to an Eligible Transferee provided that any such transaction is exempt from registration under the Securities Act. If such Purchaser should in the future decide to dispose of any of its Purchased Units, such Purchaser understands and agrees (i) that it may do so only (a) in compliance with the Securities Act and applicable state securities law, as then in effect, or (b) in the manner contemplated by any registration statement pursuant to which such securities are being offered, and (ii) that stop-transfer instructions to that effect will be in effect with respect to such securities.

Section 4.04 Nature of Purchaser. Such Purchaser represents and warrants to, and covenants and agrees with, the Partnership that, by reason of its business and financial experience, it has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Purchased Units, is able to bear the economic risk of such investment and, at the present time, would be able to afford a complete loss of such investment.

Section 4.05 Receipt of Information. Such Purchaser acknowledges and agrees that it has (i) had access to the SEC Documents and (ii) been provided a reasonable opportunity to ask questions of and receive answers from representatives of the General Partner and the Partnership regarding the Partnership’s business and operations, and such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its investment in the Purchased Units. Neither such inquiries nor any other due diligence investigations conducted at any time by such Purchaser and its representatives shall modify, amend or affect such Purchaser’s right (A) to rely on the representations and warranties contained in Article III above or (B) to indemnification or any other remedy based on, or with respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in any Basic Document.

Section 4.06 Authorization, Execution and Delivery of this Agreement. If such Purchaser is not an individual, this Agreement has been duly authorized and validly executed and delivered by or on behalf of such Purchaser, and, assuming due authorization, valid execution and delivery by each other party hereto, is enforceable against such Purchaser in accordance with its terms, except to the extent that the enforceability thereof may be limited by (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles (whether considered in a proceeding at law or in equity) relating to enforceability and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. If such Purchaser is an individual, the signature on this Agreement is genuine and such Purchaser has legal competence and capacity to execute the same and, assuming due authorization, valid execution and delivery by each other party hereto, is enforceable against such Purchaser in accordance with its terms, except to the extent that the enforceability thereof may be limited by (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles (whether considered in a proceeding at law or in equity) relating to enforceability and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

21

Section 4.07 Authorization, Execution and Delivery of the Registration Rights Agreement. If such Purchaser is not an individual, the Registration Rights Agreement has been duly authorized and validly executed and delivered by or on behalf of such Purchaser, and, assuming due authorization, valid execution and delivery by each other party thereto, is enforceable against such Purchaser in accordance with its terms, except to the extent that the enforceability thereof may be limited by (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles (whether considered in a proceeding at law or in equity) relating to enforceability and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. If such Purchaser is an individual, the signature on the Registration Rights Agreement is genuine and such Purchaser has legal competence and capacity to execute the same and, assuming due authorization, valid execution and delivery by each other party thereto, is enforceable against such Purchaser in accordance with its terms, except to the extent that the enforceability thereof may be limited by (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles (whether considered in a proceeding at law or in equity) relating to enforceability and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

Section 4.08 Restricted Securities. Such Purchaser understands that the Purchased Units are characterized as “restricted securities” under the federal securities Laws inasmuch as they are being acquired from the Partnership in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, such Purchaser represents that it is knowledgeable with respect to Rule 144 of the Commission promulgated under the Securities Act.

Section 4.09 Certain Fees. No fees or commissions will be payable by such Purchaser to brokers, finders, or investment bankers with respect to such Purchaser’s purchase of the Purchased Units or the consummation of the transactions contemplated by the Basic Documents. Such Purchaser agrees that it will indemnify and hold harmless the Partnership Entities from and against any and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by such Purchaser or alleged to have been incurred by such Purchaser in connection with the purchase of the Purchaser’s Purchased Units or the consummation of the transactions contemplated by the Basic Documents.

Section 4.10 Legend. Such Purchaser understands that the book entry evidencing the Purchased Units will bear the following legend: “THE COMMON UNITS REPRESENTING LIMITED PARTNER INTERESTS REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND MAY NOT BE OFFERED OR SOLD, UNLESS THEY HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE (AND, IN SUCH CASE, AN OPINION OF COUNSEL OR OTHER EVIDENCE REASONABLY SATISFACTORY TO CSI COMPRESSCO LP SHALL HAVE BEEN DELIVERED TO CSI COMPRESSCO LP TO THE EFFECT THAT SUCH OFFER OR SALE IS NOT REQUIRED TO BE REGISTERED UNDER THE SECURITIES ACT).”

22

Section 4.11 Reliance by the Partnership. Such Purchaser understands and acknowledges that the Purchased Units are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities laws, and that the Partnership is relying in part upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth in this Agreement in (i) concluding that the issuance and sale of the Purchased Units is a “private offering” and, as such, is exempt from the registration requirements of the Securities Act and (ii) determining the applicability of such exemption and the suitability of such Purchaser to purchase the Purchased Units.

Section 4.12 Short Selling. Such Purchaser has not engaged in any Short Sales involving Common Units owned by it between the time it first began discussions with the Partnership or the Placement Agent about the transaction contemplated by the Basic Documents and the date hereof.

Section 4.13 Ownership of Securities. Other than as previously disclosed in writing to the Partnership or as disclosed in a Schedule 13G filed with the Commission by such Purchaser or by its investment adviser or its Affiliates, such Purchaser and its Affiliates do not own five percent or more of the Company’s Common Units.

ARTICLE V.

COVENANTS

Section 5.01 Taking of Necessary Action. Each of the Parties hereto shall use its commercially reasonable efforts promptly to take or cause to be taken all action and promptly to do or cause to be done all things necessary, proper or advisable under applicable Law and regulations to consummate and make effective the transactions contemplated by the Basic Documents and the Drop-down Agreement. Without limiting the foregoing, the Partnership and each Purchaser shall each use its commercially reasonable efforts to make all filings and obtain all consents of any Governmental Authority that may be necessary or, in the reasonable opinion of the other Party, as the case may be, advisable for the consummation of the transactions contemplated by the Basic Documents.

Section 5.02 Use of Proceeds. The Partnership shall use the net proceeds from the sale of the Purchased Units for general partnership purposes, including the repayment or redemption of indebtedness.

Section 5.03 Lock-up Agreement. Without the prior written consent of the Partnership, except as specifically provided in this Agreement or as otherwise provided in the Partnership Agreement, each Purchaser and any Eligible Transferee to which Purchased Units are transferred shall not, (a) during the period commencing on the Closing Date and ending ninety (90) days following the Closing Date (the “Lock-up Period”), offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to

23

purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any of the Purchased Units, (b) during the Lock-up Period, directly or indirectly engage in any short sales or other derivative or hedging transactions with respect to the Purchased Units that are designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, of any of the economic consequences of ownership of any Purchased Units, (c) knowingly transfer any Purchased Units to any non-U.S. resident individual, non-U.S. corporation or partnership, or any other non-U.S. entity, including any foreign governmental entity, including by means of any swap or other transaction or arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, of any of the economic consequences of ownership of any Purchased Units, regardless of whether any transaction described above is to be settled by delivery of Common Units or other securities, in cash or otherwise (provided, however, that the foregoing shall not apply if, prior to any such transfer or arrangement, such individual, corporation, partnership or other entity establishes to the satisfaction of the Partnership, its entitlement to a complete exemption from tax withholding, including under Code Sections 1441, 1442, 1445 and 1471 through 1474, and the Treasury regulations thereunder), or (d) effect any transfer of Purchased Units in a manner that violates the terms of the Partnership Agreement; provided, however, that such Purchaser or such Eligible Transferee may pledge all or any portion of its Purchased Units to any holders of obligations owed by such Purchaser or such Eligible Transferee, including to the trustee for, or representative of, such holders, and any such pledge, and any foreclosure by the pledgee thereupon, shall not be considered a breach of this Section 5.03; provided, further, that such Purchaser may transfer any Purchased Units to (i) an Affiliate of such Purchaser, (ii) if such Purchaser is a collective investment vehicle, any other collective investment vehicle having the same investment manager as such Purchaser or (iii) any other Purchaser (each an “Eligible Transferee”). Notwithstanding the foregoing, any transferee receiving any Purchased Units pursuant to this Section 5.03 during the Lock-up Period shall agree to the restrictions set forth in this Section 5.03. For the avoidance of doubt, in no way does this Section 5.03 prohibit changes in the composition of any Purchaser or its partners or members so long as such changes in composition only relate to changes in direct or indirect ownership of the Purchaser or its partners or members. After the Lock-up Period, a Purchaser or other holder of Purchased Units may only transfer Purchased Units pursuant to an effective registration statement under the Securities Act or an exemption from the registration requirements of the Securities Act.

Section 5.04 No Integrated Offering. None of the Partnership, its Affiliates or any Person acting on their behalf will take any action that would require registration of the issuance of the Purchased Units under the Securities Act or cause the offering of the Purchased Units to be integrated with other offerings for purposes of (i) the Securities Act, which would require the registration of any securities under the Securities Act or (ii) any applicable approval requirement of holders of Common Units.

In addition, effective upon the filing of such Form 8-K, the Partnership acknowledges and agrees that any and all confidentiality or similar obligations in connection with the transactions contemplated by the Basic Documents under any agreement, whether written or oral, between the Partnership or any Affiliate or representative of the Partnership (including any officer, director, employee or agent of the Partnership or any such Affiliate, including the Placement Agent), on the one hand, and any of the Purchasers or any of their respective Affiliates, on the other hand, shall terminate and shall be of no further force or effect. The Partnership understands and confirms that each of the Purchasers will rely on the foregoing in effecting transactions in securities of the Partnership. The Partnership shall not, and shall cause its Affiliates and representatives (including any officer, director, partner. employee or agent of the Partnership or any such Affiliate, including the Placement Agent), not to, provide any Purchaser with any material, nonpublic information regarding the Partnership or any of its Affiliates from and after the date hereof without the express prior written consent of such Purchaser.

ARTICLE VI.

Section 6.01 Indemnification by the Partnership. The Partnership agrees to indemnify each Purchaser and, if such Purchaser is not an individual, its Affiliates and its and their officers, directors, managers, employees, agents and other representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to (i) any actual or proposed use by the Partnership of the proceeds of any sale of the Purchased Units or (ii) the breach of any of the representations, warranties or covenants of the Partnership contained in the Basic Documents, provided such claim for indemnification relating to a breach of a representation or warranty is made prior to the expiration of such representation or warranty and provided further, that no Purchaser Related Party shall be entitled to recover special, consequential (including lost profits or diminution in value) or punitive damages, except that such limitation shall not prevent any Purchaser Related Party from recovering under this Section 6.01 for any such damages to the extent that such damages are payable to a third party in connection with any third-party claims.

25

Section 6.02 Indemnification by Purchaser. Each Purchaser, severally and not jointly, agrees to indemnify the Partnership and its officers, directors, employees and agents (collectively, “Partnership Related Parties”) from, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation, or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, including, without limitation, the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them as a result of, arising out of, or in any way related to the breach of any of the representations, warranties or covenants of such Purchaser contained herein, provided such claim for indemnification relating to a breach of the representations and warranties is made prior to the expiration of such representations and warranties, and provided further, that no Partnership Related Party shall be entitled to recover special, consequential (including lost profits or diminution in value) or punitive damages.

Section 6.03 Indemnification Procedure. Promptly after any Partnership Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person, which the Indemnified Party believes in good faith is an indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party. After written notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party under this Article VI for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying Party has failed to assume the defense and employ counsel or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, the Indemnified Party.
