F1: On August 8, 2016, the Issuer entered into a Series A Preferred Unit Purchase Agreement (the "Purchase Agreement") with CSI Compressco Investment LLC ("CSI Investment") and the other purchasers party thereto (the "Purchasers"), whereby the Purchasers purchased 874,891 Series A Convertible Preferred Units representing limited partner interests in the Issuer (the "Preferred Units"). The Preferred Units were issued and sold to the Purchasers on August 8, 2016 (the "Closing"). The holders of the Preferred Units (each, a "Preferred Unitholder") will receive quarterly distributions in kind in additional Preferred Units, equal to an annual rate of 11.00% (2.75% per quarter), subject to certain adjustments. The additional 24,255 Preferred Units reported on this Form 4 were acquired by CSI Investment as quarterly, in kind distributions issued pursuant to the Purchase Agreement. A ratable portion of the Preferred Units will be converted each month over a period of thirty months beginning in the

F2: seventh calendar month following the Closing (each, a "Conversion Date"), subject to certain provisions that may delay or accelerate all or a portion of such monthly conversions. On each Conversion Date, the Preferred Units will convert into common units representing limited partner interests in the Partnership ("Common Units") in an amount equal to, with respect to each Preferred Unitholder, the number of Preferred Units held by such Preferred Unitholder divided by the number of Conversion Dates remaining, subject to certain adjustments. The conversion price (the "Conversion Price") on any Conversion Date shall equal the least of (i) $12.00, subject to certain adjustments, (ii) 93.5% of the arithmetic average of the volume-weighted average trading price (the "VWAP") on each trading day during the twenty (20) trading day period immediately prior to such Conversion Date (subject to certain adjustments), and (iii) the arithmetic average of the VWAPs on each trading day during the

F3: three (3) trading day period immediately prior to such Conversion Date (subject to certain adjustments); provided, however, that the Conversion Price shall not be less than $2.00. In addition, the Preferred Units are convertible on a one-for-one basis (subject to customary anti-dilution adjustments) by the holders of such Preferred Units at any time following May 31, 2017 so long as any conversion is not for less than $250,000 or such lesser amount, if such conversion relates to all of such Purchaser's remaining Preferred Units. In addition, upon certain events involving a change of control, each holder of the Preferred Units may elect to (a) convert its Preferred Units to Common Units at the then-applicable conversion rate, (b) if the Partnership is not the surviving entity (or if the Partnership is the surviving entity, but its Common Units will cease to be listed on a National Securities Exchange), require the Partnership or the acquiring entity, as applicable, to either (i) deliver

F4: a security in the surviving entity that has substantially similar rights, preferences and privileges as the Preferred Units or (ii) redeem each Preferred Unit held by such Preferred Unitholder at a redemption price per Preferred Unit equal to 120% of the greater of (A) $11.43 and (B) the intrinsic value of the Preferred Units determined as of the applicable date of determination or (c) if the Partnership is the surviving entity and its Common Units continue to be listed or admitted to trading on a National Securities Exchange, continue to hold the Preferred Units.

F5: The issuance of the Preferred Units to CSI Investment and the payment of the quarterly distributions thereon in kind were approved by the Board of Directors of CSI Compressco GP Inc. ("CPGP"), the general partner of the Issuer. Accordingly, the transaction reported on this Form 4 is exempt from Section 16(b) pursuant to Rule 16b-3(d)(1) under the Securities Exchange Act of 1934 (the "Exchange Act"). The transaction reported on this Form 4 is also exempt pursuant to Rule 16a-9 under the Exchange Act.

F6: The Preferred Units are perpetual in nature and have no expiration date.

("CFS"), (ii) CFS, a direct, wholly owned subsidiary of Compressco, Inc. ("CI"), (iii) CI, a direct, wholly owned subsidiary of TTI and (iv) TTI.
