ARTICLE II 
 REGISTRATION
RIGHTS 
 Section 2.01 Shelf Registration. 

(a) Shelf Registration. The Partnership shall use its commercially reasonable efforts to (i) prepare and file within 90 days
after the Closing Date an initial registration statement under the Securities Act to permit the public resale of Registrable Securities from time to time as permitted by Rule 415 (or any similar provision adopted by the Commission then in effect) of
the Securities Act (a “Registration Statement”) and (ii) cause such initial Registration Statement to become effective no later than 180 days after the Closing Date (the “Target Effective Date”).

  
 4 

 
The Partnership will use its commercially reasonable efforts to cause such initial Registration Statement filed pursuant to this Section 2.01(a) to be continuously effective under the
Securities Act, with respect to any Holder, until the expiration of the Effectiveness Period. A Registration Statement filed pursuant to this Section 2.01(a) shall be on such appropriate registration form of the Commission as shall be
selected by the Partnership so long as it permits the continuous offering of the Registrable Securities under the Securities Act at the then prevailing market prices; provided that, if the Partnership is then eligible, it shall file such
Registration Statement on Form S-3, provided further, that if the Partnership files a Registration Statement on Form S-1 and it is declared effective, the Partnership shall maintain the effectiveness of the Registration Statement then in effect
until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the Commission. A Registration Statement when declared effective (including the documents incorporated therein by reference)
will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and such Registration Statement (and, in the case of any prospectus contained in such Registration Statement, in the light of
the circumstances under which a statement is made) will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. The Registration
Statement shall contain (except if otherwise directed by the Required Holders) the “Selling Holders” and “Plan of Distribution” sections in substantially the form attached hereto as Exhibit A. As soon as
practicable following the Effective Date, but in any event within two (2) Trading Days of such date, the Partnership shall provide the Holders with written notice of the effectiveness of a Registration Statement. By 9:30 a.m. New York time on
the Business Day following the Effective Date of any Registration Statement required to be filed pursuant to this Agreement, the Partnership shall file with the Commission in accordance with Rule 424 under the Securities Act the final prospectus to
be used in connection with sales pursuant to such Registration Statement. 
 (b) Effect of Failures. If (A) a
Registration Statement required by Section 2.01(a) covering all Registrable Securities does not become or is not declared effective by the Target Effective Date, (B) on any date after the Target Effective Date sales of all of the
Registrable Securities cannot be made (other than during an Allowable Grace Period, but, for the avoidance of doubt, including during a Grace Period that is not an Allowable Grace Period) pursuant to such Registration Statement (including, without
limitation, because of a failure to keep such Registration Statement effective, a failure to disclose such information as is necessary for sales to be made pursuant to such Registration Statement or a failure to register a sufficient number of
Common Units (including as a result of the issuance of additional PIK Units pursuant to this Section 2.01(b))) or (C) at any time during the period commencing from the six (6) month anniversary of the Closing Date and ending at
such time that all of the Registrable Securities, if a Registration Statement is not available for the resale of all of the Registrable Securities, may be sold without restriction or limitation pursuant to Rule 144 and without the requirement to be
in compliance with Rule 144(c)(1), if the Partnership shall (i) fail for any reason to satisfy the requirements of Rule 144(c)(1), including, without limitation, the failure to satisfy the current public information requirements under Rule
144(c) or (ii) if the Partnership has ever been an issuer described in Rule 144(i)(1)(i) or becomes such an issuer in the future, and the Partnership shall fail to satisfy any condition set forth in Rule 144(i)(2) (collectively, the
“Obligation Failures”), then each Holder shall be entitled to a payment (with respect to each of the Holder’s Registrable Securities), as sole monetary remedy for the damages to any Holder by reason of any

  
 5 

 
such delay in or reduction of its ability to sell the Registrable Securities (which remedy shall not be exclusive of any other remedies available in equity, including, without limitation,
specific performance), as liquidated damages and not as a penalty, (i) for each non-overlapping 30-day period for the first 60 days following (x) with respect to clause (A) above, the Target Effective Date, (y) with
respect to clause (B) above, the date on which the sales of all of the Registrable Securities cannot be made and (z) with respect to clause (C) above, the day on which the Partnership fails to satisfy clauses
(i) or (ii) thereof (the “Damages Start Date”) an amount equal to 0.25% of the Liquidated Damages Multiplier, which shall accrue daily, and (ii) for each non-overlapping 30-day period beginning on the 61st day
following the Damages Start Date, an amount equal to the amount set forth in clause (i) plus an additional 0.25% of the Liquidated Damages Multiplier for each subsequent 60 days (i.e., 0.5% for 61-120 days, 0.75% for
121-180 days, and 1.0% thereafter), which shall accrue daily, up to a maximum amount equal to 1.0% of the Liquidated Damages Multiplier per non-overlapping 30 day period (the “Liquidated Damages”), until such time as such
Obligation Failure has been cured in full, and any payment of Liquidated Damages shall be prorated for any period of less than 30 days in which the payment of Liquidated Damages ceases. The Partnership shall promptly notify each Holder of any
Obligation Failure. The Liquidated Damages shall be payable within 10 Business Days after the end of each such 30 day period in immediately available funds to the account or accounts specified by the applicable Holders in writing. Any amount of
Liquidated Damages shall be prorated for any period of less than 30 days accruing during any period for which a Holder is entitled to Liquidated Damages hereunder. In the event the Partnership fails to pay any Liquidated Damages in a timely manner,
such Liquidated Damages shall bear interest at the rate of one and one-half percent (1.5%) per month (prorated for partial months) until paid in full. Notwithstanding the foregoing, if the Partnership certifies that it is unable to pay
Liquidated Damages (including, without limitation, any accrued interest thereon) in cash because such payment would result in a breach under the Partnership’s Compressco Credit Facility (as defined in the Purchase Agreement) as existing on the
date hereof (without any amendment, change or modification thereof on or after the date hereof), then the Partnership may pay the Liquidated Damages in kind in the form of the issuance of additional PIK Units, which amount of Liquidated Damages
(including, without limitation, any accrued interest thereon) due pursuant to this Section 2.01(b) shall increase the dollar amount underlying the Series A Preferred Units held by such Holder. 

(c) Waiver of Liquidated Damages. If the Partnership is unable to cause a Registration Statement to become effective on or
before the Target Effective Date, then the Partnership may request a waiver of the Liquidated Damages, and each Holder must individually consent to such request (such consent not to be unreasonably withheld). 

(d) Delay Rights. Notwithstanding anything to the contrary contained herein, at any time after the Effective Date, the
Partnership may, upon written notice to any Selling Holder whose Registrable Securities are included in a Registration Statement (a “Delay Notice”), suspend such Selling Holder’s use of any prospectus which is a part of
such Registration Statement (in which event the Selling Holder shall suspend sales of the Registrable Securities pursuant to such Registration Statement) if (i) the Partnership is pursuing an acquisition, merger, reorganization, disposition or
other similar transaction and the Partnership determines in good faith and on the advice of counsel that the Partnership’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure
of such 

  
 6 

 
transaction in such Registration Statement or (ii) the Partnership has experienced some other material non-public event, the disclosure of which at such time, in the good faith judgment of
the Partnership and its counsel, would materially and adversely affect the Partnership (each, a “Grace Period”); provided, however, that in no event shall any Grace Period exceed thirty (30) consecutive Trading
Days, or an aggregate of sixty (60) Trading Days during any three hundred sixty five (365) day period and the first day of any Grace Period must be at least five (5) Trading Days after the last day of any prior Grace Period (each, an
“Allowable Grace Period”). Each Delay Notice shall notify the Holders of the existence of material, non-public information giving rise to the delay rights being exercised pursuant to this Section 2.01(d) (provided that
in each Delay Notice the Partnership will not disclose the content of such material, non-public information to the Purchasers), and notify the Holders the dates on which the Grace Period begins. Upon disclosure of such information or the termination
of the condition described above, the Partnership shall provide prompt written notice to the Selling Holders whose Registrable Securities are included in such Registration Statement, and shall promptly terminate any suspension of sales it has put
into effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement. For purposes of determining the length of a Grace Period above, the Grace Period shall
begin on and include the date the Holders receive the Delay Notice and shall end on and include the later of the date the Holders receive a written notice of the end of such Grace Period pursuant to the immediately preceding sentence and the date
referred to in such notice. Notwithstanding anything to the contrary, the Partnership shall cause its transfer agent to deliver unlegended Common Units to a transferee of a Holder in connection with any sale of Registrable Securities with respect to
which a Holder has entered into a contract for sale, prior to such Holder’s receipt of the Delay Notice and for which such Purchaser has not yet settled, unless the Partnership and its counsel determine that such sale may violate the Securities
Act. 
 Section 2.02 Further Obligations. In connection with its obligations under this Article II, the
Partnership will: 
 (a) promptly prepare and file with the Commission such amendments (including post-effective amendments) and supplements
to a Registration Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424 promulgated under the Securities Act, as may be necessary to keep such Registration Statement
effective at all times during the Effectiveness Period, and, during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement. In the case of
amendments and supplements to a Registration Statement which are required to be filed pursuant to this Agreement (including pursuant to this Section 2.02(a)) by reason of the Partnership filing a report on Form 10-K, Form 10-Q or Form
8-K or any analogous report under the Exchange Act, the Partnership shall have incorporated such report by reference into such Registration Statement, if applicable, or shall use its commercially reasonable efforts to file such amendments or
supplements with the Commission on the same day on which the Exchange Act report is filed which created the requirement for the Partnership to amend or supplement such Registration Statement; 

(b) furnish to each Holder (i) as far in advance as reasonably practicable, but in any event at least five (5) Business Days, before
filing a Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, 

  
 7 

 
upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required
by the rules and regulations of the Commission), and provide each such Holder the opportunity to object to any information pertaining to such Holder and its plan of distribution that is contained therein and, to the extent timely received, make the
corrections reasonably requested by such Holder with respect to such information prior to filing such Registration Statement or such other registration statement and the prospectus included therein or any supplement or amendment thereto,
(ii) promptly after the same is prepared and filed with the Commission, such number of copies of such Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto as
such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Registration Statement or other registration statement and (iii) upon the effectiveness of any
Registration Statement, one copy of the prospectus included in such Registration Statement and all amendments and supplements thereto; 

(c) if applicable, use its commercially reasonable efforts to promptly register or qualify the Registrable Securities covered by any
Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Holders shall reasonably request; provided, however, that the Partnership will not be
required to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action that would subject it to general service of process in any such jurisdiction where it is not then so subject;

 (d) promptly notify each Selling Holder in writing (provided that in no event shall such notice contain any material, nonpublic
information), at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the filing of a Registration Statement or any other registration statement contemplated by this Agreement
or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to a Registration Statement or any other registration statement or any post-effective amendment thereto, when
the same has become effective; and (ii) the receipt of any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to any such
Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto; 
 (e) promptly notify each
Selling Holder in writing (provided that in no event shall such notice contain any material, nonpublic information), at any time when a prospectus relating thereto is required to be delivered by any of them under the Securities Act, of (i) the
happening of any event as a result of which the prospectus or prospectus supplement contained in a Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a
material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is
made); (ii) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of a Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings
for that purpose; or (iii) the receipt by the Partnership of any notification with respect to the suspension of the qualification 

  
 8 

 
of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Partnership agrees to, as promptly as
practicable, amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other action as is reasonably necessary to remove a stop order, suspension, threat thereof or
proceedings related thereto. By 9:30 a.m. New York City time on the Business Day following the date any post-effective amendment has become effective, the Partnership shall file with the Commission in accordance with Rule 424 under the Securities
Act the final prospectus to be used in connection with sales pursuant to such Registration Statement; 
 (f) upon request and subject to
appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission, the staff of the Commission or any other governmental agency or self-regulatory body or
other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities; 

(g) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission; 

(h) use its commercially reasonable efforts to cause all Registrable Securities registered pursuant to this Agreement to be listed on each
securities exchange or nationally recognized quotation system on which similar securities issued by the Partnership are then listed; 
 (i)
use its commercially reasonable efforts to cause Registrable Securities to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Partnership to enable
the Selling Holders to consummate the disposition of such Registrable Securities; 
 (j) provide a transfer agent and registrar for all
Registrable Securities covered by any Registration Statement not later than the Effective Date of such Registration Statement; 
 (k) enter
into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of Registrable Securities (including making appropriate officers
of the General Partner available to participate in customary marketing activities); 
 (l) if reasonably requested by a Holder,
(i) incorporate in a prospectus supplement or post-effective amendment such information as such Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with
respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; and (ii) make all required filings of
such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; 

  
 9 

 (m) if reasonably required by the Partnership’s transfer agent, the Partnership shall
promptly deliver any authorizations, certificates and directions required by the transfer agent which authorize and direct the transfer agent to transfer such Registrable Securities without legend upon sale by the Holder of such Registrable
Securities under the Registration Statement; 
 (n) use its commercially reasonable efforts to prevent the issuance of any stop order or
other suspension of effectiveness of a Registration Statement, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such
order or suspension as soon as reasonably practicable and to notify each Holder who holds Registrable Securities being sold of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat of any
proceeding for such purpose; 
 (o) make generally available to its security holders as soon as practical, but not later than ninety
(90) days after the close of the period covered thereby, an earnings statement (in form complying with, and in the manner provided by, the provisions of Rule 158 under the securities Act) covering a twelve-month period beginning not later than
the first day of the Partnership’s fiscal quarter next following the applicable Effective Date of a Registration Statement; and 
 (p)
if any Holder could reasonably be deemed to be an “underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with the Registration Statement and any amendment or supplement thereof (a
“Holder Underwriter Registration Statement”), then the Partnership will reasonably cooperate with such Holder in allowing such Holder to conduct customary “underwriter’s due diligence” with
respect to the Partnership and satisfy its obligations in respect thereof. In addition, at any Holder’s request, the Partnership will furnish to such Holder, on the date of the effectiveness of the Holder Underwriter Registration Statement and
thereafter from time to time on such dates as such Holder may reasonably request (provided that such request shall not be more frequently than on an annual basis unless such Holder is offering Registrable Securities pursuant to a Holder Underwriter
Registration Statement), (i) a “comfort” letter, dated such date, from the Partnership’s independent certified public accountants in form and substance as has been customarily given by independent certified public
accountants to underwriters in underwritten public offerings of securities by the Partnership, addressed to such Holder, (ii) an opinion, dated as of such date, of counsel representing the Partnership for purposes of the Holder Underwriter
Registration Statement, in form, scope and substance as has been customarily given in underwritten public offerings of securities by the Partnership, including standard “10b-5” negative assurance for such offerings, addressed
to such Holder and (iii) a standard officer’s certificate from the chief executive officer or chief financial officer, or other officers serving such functions, of the General Partner addressed to the Holder, as has been customarily given
by such officers in underwritten public offerings of securities by the Partnership. The Partnership will also use its reasonable efforts to provide such Holder with an opportunity to review and comment upon any such Holder Underwriter Registration
Statement, and any amendments and supplements thereto, prior to its filing with the Commission. 
 Notwithstanding anything to the contrary
in this Section 2.02, the Partnership will not name a Holder as an underwriter (as defined in Section 2(a)(11) of the Securities Act) in any 

  
 10 

 
public disclosure or filing with the Commission or any Eligible Market (provided, however, that the foregoing shall not prohibit the Partnership from including the disclosure found
in the “Plan of Distribution” section attached hereto as Exhibit A in a Registration statement), without such Holder’s express prior written consent. If the staff of the Commission requires the Partnership to name any
Holder as an underwriter (as defined in Section 2(a)(11) of the Securities Act), and such Holder does not give its express prior written consent thereto, then such Holder’s Registrable Securities shall not be included on the applicable
Registration Statement and the Partnership shall have no further obligations hereunder with respect to Registrable Securities held by such Holder, unless such Holder has not had an opportunity to conduct customary underwriter’s due diligence as
set forth in subsection (p) of this Section 2.02 with respect to the Partnership at the time such Holder’s consent is sought. 

Each Selling Holder, upon receipt of notice from the Partnership of the happening of any event of the kind described in subsection
(g) of this Section 2.02, shall promptly discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or
amended prospectus contemplated by subsection (g) of this Section 2.02 or until it is advised in writing by the Partnership that the use of the prospectus may be resumed and has received copies of any additional or
supplemental filings incorporated by reference in the prospectus, and, if so directed by the Partnership, such Selling Holder will deliver to the Partnership (at the Partnership’s expense) all copies in their possession or control, other than
permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. 

Section 2.03 Cooperation by Holders. The Partnership shall have no obligation to include Registrable Securities of a Holder
in a Registration Statement who has failed to timely furnish such information that the Partnership determines, after consultation with its counsel, is reasonably required in order for any registration statement or prospectus supplement, as
applicable, to comply with the Securities Act. To the extent the Partnership requires any information from any Holder for inclusion in a Registration statement, it shall deliver a written notice to such Holder requesting such Holder to deliver such
information within five (5) Business Days of the receipt by such Holder of such written notice. 
 Section 2.04
Expenses. 
 (a) Certain Definitions. “Registration Expenses” shall not include Selling
Expenses but otherwise means all expenses incident to the Partnership’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on a Registration Statement pursuant to Section 2.01,
and the disposition of such Registrable Securities, including, without limitation, all registration, filing, securities exchange listing and NASDAQ fees (or fees of any other principal trading market on which the Common Units then trade), all
registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing
expenses, and the fees and disbursements of counsel and independent public accountants for the Partnership, including the expenses of any special audits or “cold comfort” letters required by or incident to such performance and compliance.
“Selling Expenses” means all underwriting fees, discounts and selling commissions and transfer taxes allocable to the sale of the Registrable Securities. 

  
 11 

 (b) Expenses. The Partnership will pay all reasonable Registration Expenses, as
determined in good faith, whether or not any sale is made pursuant to a Registration Statement filed pursuant to Section 2.01. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its
Registrable Securities hereunder. In addition, except as otherwise provided in Section 2.05, the Partnership shall not be responsible for professional fees (including legal fees) incurred by Holders in connection with the exercise of
such Holders’ rights hereunder. 
 Section 2.05 Indemnification. 

(a) By the Partnership. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this
Agreement, the Partnership will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, managers, partners, employees, members, representatives and agents and each Person, if any, who controls such Selling Holder within
the meaning of the Securities Act and the Exchange Act, and their respective directors, officers, managers, partners, employees, members, representatives or agents (collectively, the “Selling Holder Indemnified Persons”),
against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) the applicable
Registration Statement or other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus
relating thereto, or any filing made in connection with the qualification of the offering under the securities or other “blue sky” laws of any jurisdiction in which Registrable Securities are offered, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading or
(ii) any violation or alleged violation by the Partnership of this Agreement, the Securities Act or the Exchange Act, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them, as
incurred, in connection with investigating, defending or resolving any such Loss or actions or proceedings; provided, however, that the Partnership will not be liable in any such case if and to the extent that any such Loss arises out of or
is based solely upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use in the applicable
Registration Statement or other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person, and
shall survive the transfer of such securities by such Selling Holder. 

  
 12 

 (b) By Each Selling Holder. Each Selling Holder agrees severally and not jointly to
indemnify and hold harmless the Partnership, the Partnership Entities, the General Partner’s directors, officers, employees and agents and each Person, who, directly or indirectly, controls the Partnership within the meaning of the Securities
Act or of the Exchange Act to the same extent as the foregoing indemnity from the Partnership to the Selling Holders, but only with respect to Losses incurred solely and to the extent of information regarding such Selling Holder furnished in writing
by or on behalf of such Selling Holder expressly for inclusion in a Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, prospectus supplement or final prospectus contained therein,
or any amendment or supplement thereto or any free writing prospectus relating thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling
Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification. 
 (c)
Notice. Promptly after receipt by an indemnified party hereunder 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 hereunder, notify
the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party other than under this Section 2.05(c) except to the extent
that the indemnifying party is materially prejudiced by such failure. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in
and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and
undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.05 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof
other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably satisfactory to the indemnified
party or (ii) 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 additional 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 reasonable expenses and fees of such separate counsel and other reasonable expenses related to such
participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified
party may be entitled to indemnification hereunder without the prior written consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete and unconditional release from liability of, and
does not contain any admission of wrongdoing by, the indemnified party. 
 (d) Contribution. If the indemnification provided
for in this Section 2.05 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold them harmless in respect of any Losses, then each such

  
 13 

 
indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is
appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant
equitable considerations; provided, however, that in no event shall any Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of net proceeds (net of Selling Expenses) received by such Selling Holder from
the sale of Registrable Securities giving rise to such indemnification. The relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other, 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 has been made by, or relates to, information supplied by such party in writing, and the parties’ relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by
any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to
include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating, defending or resolving any Loss that is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation. 

(e) Other Indemnification. The provisions of this Section 2.05 shall be in addition to any other rights to
indemnification or contribution that an indemnified party may have pursuant to law, equity, contract or otherwise. 
 Section 2.06
Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, the Partnership agrees to
use its commercially reasonable efforts to: 
 (a) make and keep public information regarding the Partnership available, as those terms are
understood and defined in Rule 144 under the Securities Act (or any similar provision then in effect), at all times from and after the date hereof and promptly notify each Holder that owns any Registrable Securities of a failure to so file; 

(b) file with the Commission in a timely manner all reports and other documents required of the Partnership under the Securities Act and the
Exchange Act at all times from and after the date hereof; and 
 (c) so long as a Holder owns any Registrable Securities, furnish
(i) to the extent accurate, forthwith upon request, a written statement of the Partnership that it has complied with the reporting requirements of Rule 144 under the Securities Act (or any similar provision then in effect), the Securities Act
and the Exchange Act, and (ii) unless otherwise available via the Commission’s EDGAR filing system, to such Holder forthwith upon request a copy of the most recent annual or quarterly report of the Partnership, and such other reports and
documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration. 

  
 14 

 Section 2.07 Transfer or Assignment of Registration Rights. The rights to
cause the Partnership to register Registrable Securities under this Article II may be transferred or assigned by each Holder to one or more transferees or assignees of Registrable Securities or securities convertible into Registrable
Securities; provided, however, that (a) unless any such transferee or assignee is an Affiliate of, and after such transfer or assignment continues to be an Affiliate of, such Holder, the amount of Registrable Securities or securities
convertible into Registrable Securities, as applicable, transferred or assigned to such transferee or assignee shall represent at least $5 million of Registrable Securities (determined by multiplying the number of Registrable Securities (on an
as-converted basis without regard to any limitations on conversions and/or redemptions of the Series A Preferred Units) owned by the average of the closing price on the NASDAQ (or any other principal trading market on which the Common Units then
trade) for the Common Units for the ten (10) Trading Days preceding the date of such transfer or assignment), (b) the Partnership is given written notice prior to any said transfer or assignment, stating the name and address of each such
transferee or assignee and identifying the securities with respect to which such registration rights are being transferred or assigned and (c) each such transferee or assignee assumes in writing responsibility for its portion of the obligations
of such transferring Holder under this Agreement.

benefit upon any Person other than the parties to this Agreement and their respective successors and permitted assigns.

 Section 3.05 Reserved. 

Section 3.06 Specific Performance. Damages in the event of breach of this Agreement by a party hereto may be difficult, if

jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives any and all defenses it may have on the 

  
 16 

 
ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief. The existence of this right will not preclude any such Person from pursuing any
other rights and remedies at law or in equity that such Person may have. 
 Section 3.07 Counterparts. This Agreement may

all claims or causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising
out of or related to any representation or warranty made in or in connection with this Agreement), will be construed in accordance with and governed by the laws of the State of New York without regard to principles of conflicts of laws. Any action
against any party relating to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of New York, and the parties hereto hereby irrevocably submit to the non-exclusive jurisdiction of any
federal or state court located within the State of New York over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the laying of venue of

in any other manner provided by law. 
 Section 3.09 Waiver of Jury Trial. THE PARTIES TO THIS AGREEMENT EACH HEREBY
WAIVE, AND AGREE TO CAUSE THEIR AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT OR (B) IN ANY WAY CONNECTED WITH OR
RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR OTHERWISE. THE
PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS
AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 

Section 3.10 Entire Agreement. This Agreement, the Purchase Agreement and the other agreements and documents referred to
herein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein and therein.
There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or in the Purchase Agreement with respect to the rights 

  
 17 

 
granted by the Partnership or any of its Affiliates or the Purchasers or any of their respective Affiliates set forth herein or therein. This Agreement, the Purchase Agreement and the other
agreements and documents referred to herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter. 

Section 3.11 Amendment. This Agreement may be amended only by means of a written amendment signed by the Partnership and
the Required Holders; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of such Holder. Any amendment, supplement or modification of or to any provision of this
Agreement, any waiver of any provision of this Agreement, and any consent to any departure by the Partnership or any Purchaser from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific
purpose for which such amendment, supplement, modification, waiver or consent has been made or given. 
 Section 3.12 No
Presumption. This Agreement has been reviewed and negotiated by sophisticated parties with access to legal counsel and shall not be construed against the drafter. 

Section 3.13 Obligations Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and acknowledges
that, other than as set forth herein, no Person other than the Purchasers, the Selling Holders, their respective permitted assignees and the Partnership shall have any obligation hereunder and that, notwithstanding that one or more of such Persons
may be a corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith shall be had against any former, current or future director, officer, employee,
agent, general or limited partner, manager, member, stockholder or Affiliate of any of such Persons or their respective permitted assignees, or any former, current or future director, officer, employee, agent, general or limited partner, manager,
member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability
whatsoever shall attach to, be imposed on or otherwise be incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of such Persons or any of their
respective assignees, or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of such Persons or their
respective permitted assignees under this Agreement or any documents or instruments delivered in connection herewith or for any claim based on, in respect of or by reason of such obligation or its creation, except, in each case, for any assignee of
any Purchaser or a Selling Holder hereunder. 
 Section 3.14 Interpretation. Article, Section and Schedule references in
this Agreement are references to the corresponding Article, Section or Schedule to this Agreement, unless otherwise specified. All Schedules to this Agreement are hereby incorporated and made a part hereof as if set forth in full herein and are an
integral part of this Agreement. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be amended, supplemented and otherwise modified from time to
time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately
following it. Whenever the 

  
 18 

 
Partnership has an obligation under this Agreement, the expense of complying with that obligation shall be an expense of the Partnership unless otherwise specified. Any reference in this
Agreement to “$” shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by a Purchaser, such action shall be in such Purchaser’s sole discretion, unless otherwise specified in this Agreement.
If any provision in this Agreement is held to be illegal, invalid, not binding or unenforceable, (a) such provision shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid, not binding or
unenforceable provision had never comprised a part of this Agreement, and the remaining provisions shall remain in full force and effect, and (b) the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the
original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the period of time before
which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period
in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,” “hereinafter,” “hereof” and
“hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires. The provision of a Table of Contents, the division of this Agreement into Articles, Sections
and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting this Agreement. 

Section 3.15 Severability. If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or
unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or
unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the
subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the
benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as
possible to that of the prohibited, invalid or unenforceable provision(s). 
 Section 3.16 Independent Nature of Purchasers’
Obligations and Rights. Each of the representations, warranties, covenants and obligations of each Purchaser under this Agreement are several and not joint with the representations, warranties, covenants and obligations of any other
Purchaser, and no Purchaser shall be responsible in any way for the representations or warranties of, or performance of the covenants or obligations by, any other Purchaser under this Agreement. The failure or waiver of performance under this
Agreement by any Purchaser does not excuse performance by any other Purchaser or the Partnership with respect to the other Purchasers. Nothing contained in this Agreement, and no action taken by any Purchaser pursuant thereto, shall be deemed to
constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the 

  
 19 

 
Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to independently
protect and enforce its rights, including the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

 Schedule A-1 

 Exhibit A 

Selling Holders 
 The
Common Units being offered by the selling holders are those issuable upon conversion of the Series A Preferred Units. We are registering the Common Units in order to permit the selling holders to offer the Common Units for resale from time to time.
Except for the ownership of the Series A Preferred Units, the selling holders have not had any material relationship with us within the past three years. 

The table below lists the selling holders and other information regarding the beneficial ownership of the Common Units. The second column
lists the number of Common Units beneficially owned by each selling holder, based on its ownership of the Series A Preferred Units, as of             , 2016, assuming conversion of
all Series A Preferred Units held by the selling holders on that date, without regard to any limitations on conversions and/or redemptions of the Series A Preferred Units. 

The third column lists the Common Units being offered by this prospectus by the selling holders. 

In accordance with the terms of a registration rights agreement with the holders of the Series A Preferred Units, this prospectus generally
covers the resale of all of 130% of the maximum of the sum of (i) the Common Units issued and issuable pursuant to the Series A Preferred Units and (ii) the Common Units issued and issuable pursuant to the PIK Units, each as of the Trading
Day immediately preceding the date the registration statement is initially filed with the Commission, subject to adjustment as provided in the registration rights agreement and in each case without regard to any limitations on the issuance of Common
Units pursuant to the terms of the Series A Preferred Units. Because the conversion price of the Series A Preferred Units may be adjusted, the number of Common Units that will actually be issued may be more or less than the number of Common Units
being offered by this prospectus. The fourth column assumes the sale of all of the Common Units offered by the selling holders pursuant to this prospectus. 

Under the terms of the Series A Preferred Units, a selling shareholder may not convert the Series A Preferred Units, to the extent such
conversion would cause such selling shareholder, together with its affiliates, to beneficially own a number of Common Units which would exceed 9.99% of our then outstanding Common Units following such conversion, excluding for purposes of such
determination Common Units issuable upon conversion of the Series A Preferred Units which have not been converted. The number of Common Units in the second column does not reflect this limitation. The selling shareholders may sell all, some or none
of their Common Units in this offering. See “Plan of Distribution.” 
 The selling holders may sell all, some or none of their
Common Units in this offering. See “Plan of Distribution.”

 Exhibit A 

 Plan of Distribution 

We are registering the Common Units issuable upon conversion of the Series A Preferred Units to permit the resale of Common Units by the
holders of the Series A Preferred Units from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling holders of the Common Units. We will bear all fees and expenses incident to our
obligation to register the Common Units. 
 The selling holders may sell all or a portion of the Common Units beneficially owned by them and
offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the Common Units are sold through underwriters or broker-dealers, the selling holders will be responsible for underwriting discounts or
commissions or agent’s commissions. The Common Units may be sold in one or more transactions at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. These
sales may be effected in transactions, which may involve crosses or block transactions, 
  

	 	•	 	on any national securities exchange or quotation service on which the Common Units may be listed or quoted at the time of sale; 

  

	 	•	 	in the over-the-counter market; 

  

	 	•	 	in transactions otherwise than on these exchanges or systems or in the over-the-counter market; 

  

	 	•	 	through the writing of options, whether such options are listed on an options exchange or otherwise; 

  

	 	•	 	in ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 

  

	 	•	 	in block trades in which the broker-dealer will attempt to sell the Common Units as agent but may position and resell a portion of the block as principal to facilitate the transaction; 

 

	 	•	 	in purchases by a broker-dealer as principal and resale by the broker-dealer for its account; 

  

	 	•	 	in exchange distributions in accordance with the rules of the applicable exchange; 

  

	 	•	 	privately negotiated transactions; 

  

	 	•	 	as short sales; 

  

	 	•	 	as sales pursuant to Rule 144; 

  

	 	•	 	as broker-dealers may agree with the selling holders to sell a specified number of such Common Units at a stipulated price per unit; 

 

	 	•	 	in a combination of any such methods of sale; and 

  

	 	•	 	in any other method permitted pursuant to applicable law. 

 If the selling holders effect such
transactions by selling Common Units to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling holders or
commissions from purchasers of the Common Units for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those
customary in the types of 

  
 Exhibit A 

 
transactions involved). In connection with sales of the Common Units or otherwise, the selling holders may enter into hedging transactions with broker-dealers, which may in turn engage in short
sales of the Common Units in the course of hedging in positions they assume. The selling holders may also sell Common Units short and deliver Common Units covered by this prospectus to close out short positions and to return borrowed Common Units in
connection with such short sales. The selling holders may also loan or pledge Common Units to broker-dealers that in turn may sell such units. 

The selling holders may pledge or grant a security interest in some or all of the Series A Preferred Units or Common Units owned by them and,
if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the Common Units from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(7) or other
applicable provision of the Securities Act of 1933, as amended, amending, if necessary, the list of selling holders to include the pledgee, transferee or other successors in interest as selling holders under this prospectus. The selling holders also
may transfer and donate the Common Units in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus. 

The selling holders and any broker-dealer participating in the distribution of the Common Units may be deemed to be “underwriters”
within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular
offering of the Common Units is made, a prospectus supplement, if required, will be distributed which will set forth the aggregate amount of Common Units being offered and the terms of the offering, including the name or names of any broker-dealers
or agents, any discounts, commissions and other terms constituting compensation from the selling holders and any discounts, commissions or concessions allowed or reallowed or paid to broker-dealers. 

Under the securities laws of some states, the Common Units may be sold in such states only through registered or licensed brokers or dealers.
In addition, in some states the Common Units may not be sold unless such units have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with. 

There can be no assurance that any selling holder will sell any or all of the Common Units registered pursuant to the registration statement,
of which this prospectus forms a part. 
 The selling holders and any other person participating in such distribution will be subject to
applicable provisions of the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the
Common Units by the selling holders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the Common Units to engage in market-making activities with respect to the Common Units.
All of the foregoing may affect the marketability of the Common Units and the ability of any person or entity to engage in market-making activities with respect to the Common Units. 

  
 Exhibit A 

 We will pay all expenses of the registration of the Common Units pursuant to the registration
rights agreement, estimated to be $         in total, including, without limitation, Securities and Exchange Commission filing fees and expenses of compliance with state securities or “blue sky”
laws; provided, however, that a selling holder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling holders against liabilities, including some liabilities under the Securities Act, in accordance with
the registration rights agreements, or the selling holders will be entitled to contribution. We may be indemnified by the selling holders against civil liabilities, including liabilities under the Securities Act, that may arise from any written
information furnished to us by the selling holder specifically for use in this prospectus, in accordance with the related registration rights agreement, or we may be entitled to contribution. 

Once sold under the registration statement, of which this prospectus forms a part, the Common Units will be freely tradable in the hands of
persons other than our affiliates.

 Section 3.05 Partnership SEC Documents. Since January 1, 2015, the Partnership’s forms, registration
statements, reports, schedules and statements required to be filed by it under the Exchange Act or the Securities Act (all such documents filed prior to the Closing Date, and all exhibits included therein and financial statements, notes and
schedules thereto and documents incorporated by reference, collectively the “Partnership SEC Documents”) have been filed with the Commission on a timely basis. The Partnership SEC Documents, at the time filed (or in the case
of registration statements, solely on the dates of effectiveness) (except to the extent corrected by a subsequent Partnership SEC Document filed on or prior to the date hereof) (a) did not contain any untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made in the case of any such documents other than a registration statement, not
misleading, (b) complied as to form in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be, and (c) complied as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the Commission with respect thereto. The financial statements of the Partnership and other financial information included in the Partnership SEC Documents were prepared in accordance with
GAAP applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by Form 10-Q of the Commission), and fairly present (subject in the case of
unaudited statements to normal and recurring and year-end audit adjustments) in all material respects the consolidated financial position of the Partnership and its consolidated Subsidiaries as of the dates thereof and the consolidated results of
its operations and cash flows of the Partnership and its consolidated Subsidiaries for the periods then ended. The independent auditor of the Partnership as of the date of the most recent audited balance sheet of the Partnership is an independent
registered public accounting firm with respect to the Partnership and has not resigned or been dismissed as independent registered public accountants of the Partnership as a result of or in connection with any disagreement with the Partnership on
any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures. Since the date of the most recent balance sheet of the Partnership audited by such auditor, (i) the interactive data in eXtensible
Business Reporting Language included or incorporated by reference in the Partnership SEC Documents fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and
guidelines applicable thereto and (ii) based on an annual evaluation of disclosure controls and procedures, the Partnership is not aware of (x) except as disclosed in the Partnership SEC Documents, any significant deficiency or material
weakness in the design or operation of internal controls over financial reporting that are likely to adversely affect its ability to record, process, summarize and report financial data or (y) any fraud, whether or not material, that involves
management or other employees who have a significant role in the internal controls over financial reporting of the Partnership. 

  
 14 

 Section 3.06 No Material Adverse Change; Absence of Changes. Except as
expressly set forth in the Partnership SEC Documents, since December 31, 2015 through the date hereof no Material Adverse Effect has occurred. Except as disclosed in the Partnership SEC Documents since December 31, 2015, the Partnership
has not declared or paid any dividends and neither the Partnership nor any of its Subsidiaries has, (i) sold any assets, individually or in the aggregate, in excess of $250,000 outside of the ordinary course of business or (ii) had capital
expenditures, individually or in the aggregate, in excess of $250,000. Neither the Partnership nor any of its Subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy insolvency, reorganization,
receivership, liquidation or winding up nor does the Partnership have any knowledge or reason to believe that any of its or any of its Subsidiaries’ respective creditors intend to initiate involuntary bankruptcy proceedings or any actual
knowledge of any fact that would reasonably lead a creditor to do so. The Partnership and its Subsidiaries, individually and on a consolidated basis, are not as of the date hereof, and after giving effect to the transactions contemplated hereby to
occur at the Closing, will not be Insolvent. 
 Section 3.07 No Registration Required. Assuming the accuracy of the
representations and warranties of each Purchaser contained in Article IV, the issuance and sale of the Purchased Units and Securities pursuant to this Agreement is exempt from registration requirements of the Securities Act, and neither the
Partnership nor any authorized Representative acting on its behalf has taken or will take any action hereafter that would cause the loss of such exemption. 

Section 3.08 No Registration Rights. None of the sale of the Securities as contemplated by this Agreement, the entry into
the Registration Rights Agreement and the filing of any registration statement contemplated by the Registration Rights Agreement give rise to any rights for or relating to the registration of any other securities of the Partnership. 

Section 3.09 Litigation. Except as set forth in the Partnership SEC Documents, there are (i) no legal or governmental
proceedings pending or, to the knowledge of the Partnership, threatened, against any of the Partnership Entities or to which any Property or asset of any such entity is subject and (ii) no injunction, restraining order or order of any nature
issued by a federal or state court or foreign court of competent jurisdiction to which any of the Partnership or the Partnership Entities is or may be subject, that would, in either case, reasonably be expected to have, individually or in the
aggregate, a Material Adverse Effect or which challenges the validity of any of the Transaction Documents or the right of any of the Partnership or the General Partner to enter into any of the Transaction Documents or to consummate the transactions
contemplated hereby and thereby and, to the knowledge of the Partnership, no such proceedings are threatened by Governmental Authorities or others. 

Section 3.10 No Default. (i) None of the Partnership or any of its Subsidiaries is in violation of any law, statute,
ordinance, administrative or governmental rule or regulation applicable to it or of any decree of any Governmental Authority having jurisdiction over it and (ii) none of the Partnership or its Subsidiaries is in breach, default (or an event
that, with notice or lapse of time or both, would constitute such an event) or violation in the performance of any obligation, covenant or condition contained in any bond, debenture, note or any other evidence of indebtedness or in any agreement,
indenture, lease or other instrument to which it is a party or by which it or any of its properties may be bound, which breach, default or violation would, in 

  
 15 

 
either case, if continued, reasonably be expected to have a Material Adverse Effect or materially impair the ability of the Partnership or the General Partner to perform its obligations under the
Transaction Documents. The Partnership Entities possess all certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the failure to possess such
certificates, authorizations or permits would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, and none of the Partnership Entities has received any notice of proceedings relating to the revocation or
modification of any such certificate, authorization or permit, except where such potential revocation or modification would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

Section 3.11 No Conflicts. None of (a) the offering, issuance and sale by the Partnership of the Securities and the
application of the proceeds therefrom, (b) the execution, delivery and performance of the Transaction Documents, or (c) the consummation of the transactions contemplated thereby (i) constitutes or will constitute a violation of the
Organizational Documents of the Partnership or the General Partner, (ii) constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under or
give to others any right of termination, amendment, acceleration or cancellation of, any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which the Partnership or the General Partner is a party or by
which any of them or any of their respective properties may be bound, (iii) violates or will violate any statute, Law, Permit or regulation or any order, judgment, decree or injunction of any court or Governmental Authority or body having
jurisdiction over the Partnership or the General Partner or any of their properties in a proceeding to which any of them or their property is or was a party, or (iv) results or will result in the creation or imposition of any Lien upon any
property or assets of the Partnership or the General Partner, which conflicts, breaches, violations, defaults or liens, in the case of clauses (ii), (iii) or (iv), would, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect or materially impair the ability of the Partnership to consummate the transactions contemplated by this Agreement. 

Section 3.12 Authority; Enforceability. The Partnership has all limited partnership power and authority to issue, sell and
deliver the Securities, in accordance with and upon the terms and conditions set forth in this Agreement and the Partnership Agreement. All partnership or limited liability company action, as the case may be, required to be taken by the General
Partner and the Partnership for the authorization, issuance, sale and delivery of the Securities, the execution and delivery of the Transaction Documents and the consummation of the transactions contemplated thereby shall have been validly taken. No
approval from the holders of outstanding Common Units is required under the Partnership Agreement or the rules of the Exchange in connection with the Partnership’s issuance and sale of the Securities to the Purchasers. Each of the Transaction
Documents has been duly and validly authorized and has been or, with respect to the Transaction Documents to be delivered at the Closing, will be, validly executed and delivered by the Partnership or the General Partner, as the case may be, and

insurance for which the failure to be outstanding and duly in force would not reasonably be expected to have a Material Adverse Effect. Neither the Partnership nor any of its Subsidiaries has any reason to believe that it will

  
 18 

 
not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost
that would not have a Material Adverse Effect. 
 Section 3.22 Books and Records; Sarbanes-Oxley Compliance.

summarized and communicated to the Partnership’s management, including its principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. The Partnership has carried out
evaluations of the effectiveness of its disclosure controls and procedures as of the end of the most recently completed fiscal quarter covered by the Partnership’s periodic reports filed with the Commission, and such disclosure controls and
procedures are, except as described in the Partnership SEC Documents, effective in all material respects to perform the functions for which they were established.

received any notice of delisting. The issuance and sale of the Purchased Units and the PIK Units pursuant to the Partnership Agreement and issuance of Conversion Units and Additional Conversion Units upon conversion of the Purchased Units and the
PIK Units does not contravene Exchange rules and regulations. Without limiting the generality of the foregoing, the Partnership is not in violation of any of the rules, regulations or requirements of the Exchange and has no knowledge of any facts or
circumstances that would reasonably lead to delisting or suspension of the Common Units by the Exchange in the foreseeable future. During the two (2) years prior to the date hereof, the Common Units have been designated for quotation on the

such obtained material Environmental Permits required for their operations as currently conducted, except as (i) would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or (ii) have been

Transaction Documents by such Purchaser and the consummation by such Purchaser of the transactions contemplated thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default
under, any material agreement to which such Purchaser is a party or by which such Purchaser is bound or to which any of the property or assets of such Purchaser is subject, (b) conflict with or result in any violation of the provisions of the
organizational documents of such Purchaser, or (c) 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 (a) and (c), for such conflicts, breaches, violations or defaults as would not prevent the consummation by such Purchaser of the transactions contemplated by the Transaction Documents. 

Section 4.04 Certain Fees. No fees or commissions are or will be payable by such Purchaser to brokers, finders or
investment bankers retained by such Purchaser with respect to the purchase of any of the Purchased Units or the consummation of the transactions contemplated by this Agreement, except for fees or commissions for which the Partnership is not
responsible. 
 Section 4.05 Unregistered Securities. 

(a) Accredited Investor Status; Sophisticated Purchaser. Such Purchaser is an “accredited investor” within the meaning of Rule
501 under the Securities Act and is able to bear the risk of its investment in the Securities. Such Purchaser has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the purchase
of the Securities. 
 (b) Information. Such Purchaser and its Representatives have been furnished with all materials relating to the
business, finances and operations of the Partnership that have 

  
 27 

 
been requested and materials relating to the offer and sale of the Securities that have been requested by such Purchaser. Such Purchaser and its Representatives have been afforded the opportunity
to ask questions of the Partnership. Neither such inquiries nor any other due diligence investigations conducted at any time by such Purchasers and its Representatives shall modify, amend or affect such Purchasers’ right (i) to rely on the
Partnership’s representations and warranties contained in Article III above or (ii) 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 Transaction Document. Such Purchaser understands that its purchase of the Purchased Units involves a high degree of risk. 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 acquisition of the Purchased Units. 
 (c)
Residency. Such Purchaser shall cooperate reasonably with the Partnership to provide any information necessary for any applicable securities filings. Such Purchaser is treated as a “United States person” within the meaning of
Section 7701(a)(30) of the Code, or a disregarded entity of such United States person. 
 (d) Legends. Such Purchaser
understands that, until such time as the Purchased Units have been registered pursuant to the provisions of the Securities Act, or the Purchased Units are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any
restriction as to the number of securities as of a particular date that can then be immediately sold, the Purchased Units will bear a restrictive legend as provided in the Partnership Agreement. Each Purchaser understands that, until such time as
the Conversion Units have been registered pursuant to the provisions of the Securities Act, or the Conversion Units are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any restriction as to the number of
securities as of a particular date that can then be immediately sold, the Conversion Units will bear a restrictive legend as provided in the Partnership Agreement. 

(e) Purchase Representation. Such Purchaser is purchasing the Purchased Units for its own account and not with a view to distribution
in violation of any securities laws. Such Purchaser has been advised and understands that, except as contemplated by the Registration Rights Agreement, neither the Purchased Units nor the Conversion Units have been or will be registered under the
Securities Act or under the “blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the Securities
Act or pursuant to another available exemption from the registration requirements of the Securities Act). Such Purchaser has been advised and understands that the Partnership, in issuing the Purchased Units, is relying upon, among other things, the
representations and warranties of such Purchaser contained in this Article IV in concluding that such issuance is a “private placement” and is exempt from the registration provisions of the Securities Act. 

(f) Rule 144. Such Purchaser understands that there is no public trading market for the Purchased Units and that none is expected to
develop. Each Purchaser has been advised and is aware of the provisions of Rule 144 promulgated under the Securities Act. 
 (g) Reliance
by the Partnership. Such Purchaser understands that the Purchased Units are being offered and sold in reliance on a transactional exemption from the 

  
 28 

 
registration requirements of federal and state securities laws and that the Partnership is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and
understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Purchased Units and the Conversion Units issuable upon conversion thereof. 

Section 4.06 Sufficient Funds. Such Purchaser will have available to it at the Closing sufficient funds to enable such
Purchaser to pay in full at the Closing the entire amount of such Purchaser’s Funding Obligation in immediately available cash funds. 

ARTICLE V 
 COVENANTS

 Section 5.01 Conduct of Business. During the period commencing on the date of this Agreement and ending on the
Closing Date, each of the Partnership Entities will use reasonable best efforts to conduct its business in the ordinary course of business, preserve intact its existence and business organization, Permits, goodwill and present business relationships
with all material customers, suppliers, licensors, distributors and others having significant business relationships with the Partnership Entities (or any of them), to the extent the Partnership believes in its reasonable discretion that such
relationships are and continue to be beneficial to the Partnership Entities and their businesses. 
 Section 5.02 Form D and Blue
Sky. The Partnership agrees to file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof to each Purchaser promptly after such filing. The Partnership shall, on or before the Closing Date, take
such action as the Partnership shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Securities for sale to the Purchasers at the Closing pursuant to this Agreement under applicable securities or “Blue
Sky” laws of the states of the United States (or to obtain an exemption from such qualification), and shall provide evidence of any such action so taken to the Purchasers on or prior to the Closing Date. The Partnership shall make all filings
and reports relating to the offer and sale of the Securities required under applicable securities or “Blue Sky” laws of the states of the United States following the Closing Date. 

Section 5.03 Reporting Status. For so long as any Series A Preferred Units are outstanding (the “Reporting
Period”), the Partnership shall use its commercially reasonably efforts to timely file, and in all cases file, all reports required to be filed with the Commission pursuant to the Exchange Act, and the Partnership shall not terminate
its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would no longer require or otherwise permit such termination, and the Partnership shall take commercially
reasonable efforts to maintain its eligibility to register the Conversion Units and the Additional Conversion Units for resale on Form S-3. 

Section 5.04 Use of Proceeds. The Partnership will use the proceeds from the sale of the Securities to reduce outstanding
Indebtedness. 
 Section 5.05 Pledge of Securities. The Partnership acknowledges and agrees that the Securities may be
pledged by a Purchaser in connection with a bona fide margin agreement or 

  
 29 

 
other loan or financing arrangement that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no
Purchaser effecting a pledge of Securities shall be required to provide the Partnership with any notice thereof or otherwise make any delivery to the Partnership pursuant to this Agreement or any other Transaction Document; provided that a Purchaser
and its pledgee shall be required to comply with the provisions of Section 4.05(f) hereof in order to effect a sale, transfer or assignment of Securities to such pledgee. The Partnership hereby agrees to execute and deliver such
documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by a Purchaser. 

Section 5.06 Disclosure of Transactions and Other Material Information. On or before the fourth Business Day following the
date of this Agreement, the Partnership shall issue a press release and file a Current Report on Form 8-K (provided that such press release shall be issued and such Form 8-K shall be filed at the same time), in each case, reasonably acceptable to
the Purchasers, describing the terms of the transactions contemplated by the Transaction Documents in the form required by the Exchange Act and attaching the material Transaction Documents (including, without limitation, this Agreement (and all
schedules and exhibits to this Agreement) and the form of the Registration Rights Agreement as exhibits to such filing (including all attachments), the “8-K Filing”). In addition, the Partnership hereby covenants and agrees
that it shall include in the 8-K Filing any information that constitutes, or could reasonably be expected to constitute, material, nonpublic information regarding the Partnership or any of its Subsidiaries received by any of the Purchasers from the
Partnership, any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents. Accordingly, immediately after the filing of the 8-K Filing with the Commission, no Purchaser shall be in possession of any
material, nonpublic information received from the Partnership, any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents, that is not disclosed in the 8-K Filing. In addition, effective upon the filing
of the 8-K Filing, the Partnership acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Partnership, any of its Subsidiaries or any of their respective officers,
directors, affiliates, employees or agents, on the one hand, and any of the Purchasers or any of their 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 each of its Subsidiaries and its and each of their respective officers, directors, affiliates, employees
and agents, not to, provide any Purchaser with any material, nonpublic information regarding the Partnership or any of its Subsidiaries from and after the date hereof without the express prior written consent of such Purchaser. If a Purchaser has,
or believes it has, received any such material, nonpublic information regarding the Partnership or any of its Subsidiaries from the Purchaser, any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents,
it may provide the Partnership with written notice thereof. The Partnership shall, to the extent it believes such information is material, nonpublic information, within two (2) Trading Days of receipt of such notice, make public disclosure of
such material, nonpublic information. To the extent that the Partnership delivers any material, non-public information to a Purchaser without such Purchaser’s consent, the Partnership hereby covenants and agrees that such Purchaser shall not
have any duty of confidentiality to the Partnership, any of its Subsidiaries, or any of their respective, officers, directors, Affiliates, employees or agents with respect to, or a duty to the Partnership, any of its

  
 30 

 
Subsidiaries, or any of their respective, officers, directors, Affiliates, employees or agents not to trade on the basis of, such material, non-public information. Subject to the foregoing,
neither the Partnership, its Subsidiaries nor any Purchaser shall issue any press releases or any other public statements with respect to the transactions contemplated hereby; provided, however, that the Partnership shall be entitled, without
the prior approval of any Purchaser, to make any press release or other public disclosure with respect to such transactions (i) in substantial conformity with the 8-K Filing and contemporaneously therewith or (ii) as is required by
applicable law and regulations (provided that in the case of clause (i) each Purchaser shall be consulted by the Partnership in connection with any such press release or other public disclosure prior to its release). To the extent the
Partnership is required to deliver a notice containing material, nonpublic information relating to the Partnership or its Subsidiaries (a “MNPI Notice”) to a Purchaser pursuant to any of the Transaction Documents, the
Partnership shall request from such Purchaser whether it wishes to receive such MNPI Notice without identifying such material, nonpublic information, and the Partnership shall only proceed to (and will only be required to) deliver such MNPI Notice
to such Purchaser if such Purchaser consents in writing to receive such MNPI Notice. If a Purchaser does not consent in writing to receive a MNPI Notice, such Purchaser will be deemed to have waived its right to receive such MNPI Notice and the
Partnership shall have the ability to exercise its rights with respect to the matters for which such MNPI Notice is required as provided in the Transaction Documents. 

Section 5.07 Notice of Disqualification Events. The Partnership will notify the Purchasers in writing, prior to the Closing
Date of (i) any Disqualification Event relating to any Issuer Covered Person and (ii) any event that would, with the passage of time, become a Disqualification Event related to any Issuer Covered Person. 

Section 5.08 Listing of Units. Prior to the Closing, the Partnership shall list, subject to notice of issuance, the
Conversion Units on the Exchange. The Partnership shall obtain approval for listing, subject to notice of issuance, of all Additional Conversion Units on the Exchange prior to each applicable date on which the PIK Units convertible into such
Additional Conversion Units are distributed by the Partnership. The Partnership shall use its reasonable best efforts to maintain such listing of all Conversion Units and Additional Conversion Units from time to time issuable under the terms of the
Transaction Documents. The Partnership shall use commercially reasonable efforts to maintain the authorization of the Common Units on the Exchange. Neither the Partnership nor any of its Subsidiaries shall take any action which would reasonably be
expected to result in the delisting or suspension of the Common Units on the Exchange, unless the Partnership is in compliance with the applicable provisions governing a Series A Change of Control or Series A Cash COC Event (each, as defined in the
Partnership Agreement) set forth in the Partnership Agreement. 
 Section 5.09 Cooperation; Further Assurances. Each of
the Partnership and the Purchasers shall use its respective reasonable best efforts to obtain all approvals and consents required by or necessary to consummate the transactions contemplated by this Agreement and the other Transaction Documents. Each
of the Partnership and the Purchasers agrees to execute and deliver all such documents or instruments, to take all appropriate action and to do all other things it determines to be necessary, proper or advisable under applicable Laws and regulations
or as otherwise reasonably requested by the other to consummate the transactions contemplated by this Agreement. 

  
 31 

 Section 5.10 Transfer Restrictions. Without the prior written consent of the
Partnership, except as specifically provided in this Agreement, each Purchaser and its Affiliates shall not 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 purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any of the Purchased Units (including any PIK Units received through distributions by the Partnership); provided, however, that such Purchaser may
transfer any Purchased Units or PIK Units if the transferee will own at least $5 million of the Series A Preferred Units, after giving effect to such transfer; provided further, that such Purchaser may transfer any Purchased Units or PIK
Units to an Affiliate of such Purchaser or to any other Purchaser unless any such transfer would cause a technical termination under Section 708 of the Code. Other than with respect to transfers by a Purchaser to an Affiliate, each Purchaser
agrees to unconditionally and irrevocably grant to the Partnership and TETRA a right of first refusal to purchase any Series A Preferred Units that such Purchaser may propose to transfer. Notwithstanding the foregoing, any transferee receiving any
Purchased Units pursuant to this Section 5.10 shall agree to the restrictions set forth in this Section 5.10. Notwithstanding anything herein to the contrary, nothing in this Section 5.10 or otherwise in this
Agreement shall restrict a Purchaser from entering 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 such Purchaser’s Securities; provided,
however that the Purchasers may not transfer any of the Securities to a 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, any of the economic consequences of the Securities, regardless of whether such
transaction is to be settled by delivery of Securities, Common Units or other securities, in cash or otherwise. 
 Section 5.11
Partnership Lock-Up. For a period commencing on the date hereof and ending on December 6, 2016, the Partnership will not, without the prior written consent of the Purchasers, directly or indirectly, (A) offer for sale, sell,
pledge, grant any option to purchase or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Units or securities
convertible into or exercisable or exchangeable for Common Units (other than (i) the Purchased Units as contemplated by the Transaction Documents, (ii) Common Units issued pursuant to employee benefit plans, qualified option plans or other
employee compensation plans existing on the date hereof (including, without limitation, Common Units issued pursuant to the long-term incentive plan of the Partnership) or (iii) up to an aggregate sum of $10 million of additional Series A
Parity Securities (as defined in the Partnership Agreement) and/or Indebtedness (other than Indebtedness incurred under the Compressco Credit Facility or the Indenture, each as may be amended from time to time)), or sell or grant options, rights or
warrants with respect to any Common Units or securities convertible into or exchangeable for Common Units (other than the grant of such options, rights or warrants pursuant to employee benefit plans, qualified option plans or other employee
compensation plans existing on the date hereof (including, without limitation, Common Units issued pursuant to the long-term incentive plan of the Partnership)), (B) 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 such Common Units, whether any such transaction described in clause (A) or (B) above is to be settled by delivery of Common Units or other securities, in
cash or otherwise, be a party to any solicitations, negotiations or discussions with regard to the foregoing or (C) publicly disclose the intention to do any of the foregoing, in each case without the prior written consent of the Purchasers.

  
 32 

 Section 5.12 No Integrated Offering. None of the Partnership, its
Subsidiaries, their Affiliates or any Person acting on their behalf will take any action or steps referred to in Section 3.19 that would require registration of the issuance of any of the Securities under the Securities Act or cause the
offering of any of the Securities to be integrated with other offerings for purposes of any such applicable shareholder approval provisions. 

Section 5.13 Tax Estimates. On or before March 15 of each year, the Partnership shall provide each Purchaser that
continues to own Purchased Units a good faith estimate (and reasonable supporting calculations) of whether there was sufficient Unrealized Gain attributable to the Partnership property as of December 31 of the previous year such that, if any of
such Purchaser’s Series A Preferred Units were converted to Common Units and such Unrealized Gain was allocated to such Purchaser pursuant to Section 5.5(d)(iii) of the Partnership Agreement (taking proper account of allocations of higher
priority), such Purchaser’s Capital Account in respect of its Common Units would be equal to the Per Unit Capital Amount for an Initial Common Unit without any need for corrective allocations under Section 6.2(i) of the Partnership
Agreement. 
 In addition, following receipt of a written request from a Purchaser that continues to own Purchased Units, the Partnership
shall provide such Purchaser with a good faith estimate (and reasonable supporting calculations) of whether there is sufficient Unrealized Gain attributable to the Partnership property on the date of such request such that, if any of such
Purchaser’s Series A Preferred Units were converted to Common Units and such Unrealized Gain was allocated to such Purchaser pursuant to Section 5.5(d)(iii) of the Partnership Agreement (taking proper account of allocations of higher
priority), Purchaser’s Capital Account in respect of its Common Units would be equal to the Per Unit Capital Amount for an Initial Common Unit without any need for corrective allocations under Section 6.2(i) of the Partnership Agreement.
Each Purchaser shall be entitled to make such a request not more than once per calendar year. 
 For purposes of this
Section 5.13, all capitalized terms used but not defined herein shall have the meanings assigned to them in the Partnership Agreement. 

Section 5.14 Distribution Reimbursement. Each of the Purchasers agrees that if it exercises its Conversion Option, it shall
pay to the Partnership, by wire transfer of immediately available funds to a bank account designated by the General Partner, within seven (7) calendar days of the payment of each cash distribution paid by the Partnership with respect to the
Common Units issued in connection with the exercise of such Conversion Option by such Holders, an amount of cash equal to such cash distributions paid to each such Common Unit with respect to each quarter during the Conversion Period, irrespective
of whether such Purchaser continues to hold such Common Units at the time the Partnership pays such cash distributions. For the avoidance of doubt, no Purchaser shall be required to pay to the Partnership an amount of cash equal to any cash
distributions paid by the Partnership with respect to such Common Units for quarters beginning after the termination of the Conversion Period. Each Purchaser agrees that no transfer of the Securities before the termination of the Conversion Period
shall be recognized by the Partnership unless the transferee agrees to be bound by the terms of this Section 5.14 and executes and delivers to the Partnership an acknowledgment and agreement to such effect. 

  
 33 

 Section 5.15 UBTI. The Schedule K-1s provided to the Purchasers shall include
such Purchaser’s distributive share of “unrelated business taxable income.” 
 ARTICLE VI 

INDEMNIFICATION, COSTS AND EXPENSES 

Section 6.01 Indemnification by the Partnership. The Partnership agrees to indemnify each Purchaser and its Representatives
(collectively, “Purchaser Related Parties”) from costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever, 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 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), whether or not involving a Third-Party Claim, as a result of, arising out of, or in any way related to (a) the failure of any of the representations or warranties made by the Partnership contained herein to be true and
correct as of the date made or (b) the breach of any covenants of the Partnership contained herein, in any other Transaction Document or in any other certificate, instrument or document contemplated to be delivered hereby, provided that,
in the case of the immediately preceding clause (a), such claim for indemnification is made prior to the expiration of the survival period of such representation or warranty; provided, however, that for purposes of
determining when an indemnification claim has been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Partnership shall constitute the date
upon which such claim has been made; provided, further, that the Partnership shall not be required to indemnify Purchaser Related Parties for the first $50,000 in the aggregate of such costs, losses, liabilities, damages, or expenses incurred
by the Purchaser Related Parties. No Purchaser Related Party shall be entitled to recover special, indirect, exemplary, incidental, lost profits, speculative or punitive damages under this Section 6.01; provided, however,
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 direct damages in the form of diminution in value or are payable to a
third party in connection with any Third-Party Claims. 
 Section 6.02 Indemnification Procedure. 

(a) A claim for indemnification for any matter not involving a Third-Party Claim may be asserted by notice to the party from whom
indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any indemnification which it may claim in accordance with this Article VI, except as otherwise
provided in Section 6.01. 

  
 34 

 (b) As soon as reasonably practicable after any 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 (each a “Third-Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such Third-Party Claim, 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 Third-Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified
Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or settle, it shall promptly, and in no event later than ten (10) days, notify the
Indemnified Party of its intention to do so, and the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and the settlement thereof. Such cooperation of the
Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying
Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of such asserted liability; 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,
within ten (10) Business Days of when the Indemnified Party provides written notice of a Third-Party Claim, failed to assume the defense or employ counsel reasonably acceptable to the Indemnified Party and to notify the Indemnified Party of
such assumption 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 and unconditional release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party or its Affiliates. The remedies
provided for in this Section 6.02 are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise. 

Section 6.03 Tax Matters. All indemnification payments under this Article VI shall be adjustments to the
Purchaser’s Purchase Price except as otherwise required by applicable Law. 

  
 35 

 ARTICLE VII 

TERMINATION 

Section 7.01 Termination. This Agreement may be terminated at any time prior to the Closing: 

(a) With respect to any particular Purchaser, by mutual written consent of the Partnership and such Purchaser; 

(b) With respect to any particular Purchaser, by written notice from either the Partnership or such Purchaser if any Governmental Authority
with lawful jurisdiction shall have issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the transactions contemplated by the Transaction Documents and such order, decree, ruling or
other action is or shall have become final and nonappealable; or 
 (c) by written notice from the Partnership or a Purchaser, with respect
to itself but not any other Purchaser, if the Closing does not occur by 11:59 p.m. on October 4, 2016 Houston, Texas time; provided, however, that no party may terminate this Agreement pursuant to this Section 7.01(c)
if such party is, at the time of providing such written notice, in breach of any of its obligations under this Agreement. 

Section 7.02 Certain Effects of Termination. In the event that this Agreement is terminated pursuant to
Section 7.01: 
 (a) except as set forth in Section 7.02(b), this Agreement shall become null and void and have no
further force or effect, but the parties shall not be released from any liability arising from or in connection with any breach hereof occurring prior to such termination; and 

(b) regardless of any purported termination of this Agreement, the provisions of Article VI and all indemnification rights and
obligations of the Partnership and the Purchasers thereunder, this Section 7.02 and the provisions of Article VIII shall remain operative and in full force and effect as between the Partnership and the Purchasers. 

ARTICLE VIII 

MISCELLANEOUS 

Section 8.01 Expenses. All costs and expenses, including fees and disbursements of financial advisers, legal counsel and
accountants, incurred in connection with the Transaction Documents and the transactions contemplated thereby shall be paid by the party incurring such costs and expenses. 

Section 8.02 Interpretation. Article, Section, Schedule and Exhibit references in this Agreement are references to the
corresponding Article, Section, Schedule or Exhibit to this Agreement, unless otherwise specified. All Exhibits and Schedules to this Agreement are hereby incorporated and made a part hereof as if set forth in full herein and are an integral part of
this Agreement. All references to instruments, documents, Contracts and agreements are references to such instruments, documents, Contracts and agreements as the same may be amended, 

  
 36 

 
supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to
limit any general statement that it follows to the specific or similar items or matters immediately following it. Whenever the Partnership has an obligation under the Transaction Documents, the expense of complying with that obligation shall be an
expense of the Partnership unless otherwise specified. Any reference in this Agreement to “$” shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by a Purchaser, such action shall be in such
Purchaser’s sole discretion, unless otherwise specified in this Agreement. If any provision in the Transaction Documents is held to be illegal, invalid, not binding or unenforceable, (a) such provision shall be fully severable and the
Transaction Documents shall be construed and enforced as if such illegal, invalid, not binding or unenforceable provision had never comprised a part of the Transaction Documents, and the remaining provisions shall remain in full force and effect so
long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question
does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations
to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s), and (b) the parties hereto shall
negotiate in good faith to modify the Transaction Documents so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally
contemplated to the greatest extent possible. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to the Transaction Documents, the date that is the reference date in
calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice
versa. The words such as “herein,” “hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise requires.
The provision of a Table of Contents, the division of this Agreement into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or interpreting
this Agreement. 
 Section 8.03 Survival of Provisions. (A) The representations and warranties set forth in

 Section 8.08 Removal of Legend. In connection with a sale of the Conversion Units or Additional
Conversion Units by a Purchaser in reliance on Rule 144 promulgated under the Securities Act, the applicable Purchaser or its broker shall deliver to the Partnership a broker representation letter providing to the Partnership any information the
Partnership deems necessary to determine that the sale of such Units is made in compliance with Rule 144 promulgated under the Securities Act, including, as may be appropriate, a certification as to facts allowing the Partnership to determine
whether such Purchaser is or is not an affiliate of the Partnership (as defined in Rule 144 promulgated under the Securities Act) and a certification as to the length of time the such Units have been held. Upon receipt of such representation letter,
the Partnership shall promptly remove the notation of a restrictive legend in such Purchaser’s or the book-entry account maintained by the Partnership, including the legend referred to in Section 4.05, and the Partnership shall bear
all costs (or reimburse such Purchaser for such reasonable 

  
 39 

 
costs) associated therewith. At such time as the Conversion Units or Additional Conversion Units have been sold pursuant to an effective registration statement under the Securities Act or have
been held by any Purchaser for more than one year where such Purchaser is not, and has not been in the preceding three months, an affiliate of the Partnership (as defined in Rule 144 promulgated under the Securities Act), if the book-entry account
of such Units still bears the notation of the restrictive legend referred to in Section 4.05, the Partnership agrees, upon request of the Purchaser or permitted assignee, to take all steps necessary to promptly effect the removal of the
legend described in Section 4.05 from such Units, and the Partnership shall bear all costs (or reimburse such Purchaser for such reasonable costs) associated therewith, regardless of whether the request is made in connection with a sale
or otherwise, so long as such Purchaser or its permitted assigns provide to the Partnership any information the Partnership deems reasonably necessary to determine that the legend is no longer required under the Securities Act or applicable state
laws, including (if there is no such registration statement) a certification as to facts allowing the Partnership to determine whether such Purchaser is or is not an affiliate of the Partnership (as defined in Rule 144 promulgated under the
Securities Act), as well as a covenant to inform the Partnership if it should thereafter become an affiliate (as defined in Rule 144 promulgated under the Securities Act) and to consent to the notation of an appropriate restriction, and a
certification as to the length of time such Units have been held. The Partnership shall cooperate with each Purchaser to effect the removal of the legend referred to in Section 4.05 at any time such legend is no longer appropriate. 

Section 8.09 Entire Agreement. This Agreement, the other Transaction Documents and the other agreements and documents
referred to herein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the agreement and understanding of the parties hereto in respect of the subject matter contained herein

prosecute an action in any court of competent jurisdiction to enforce specific performance of such covenant or agreement or seek any other equitable relief.

 Schedule A 

 EXHIBIT A 

FORM OF OPINION OF VINSON & ELKINS L.L.P. 

Capitalized terms used but not defined herein have the meanings assigned to such terms in the Series A Preferred Unit Purchase Agreement (the
“Purchase Agreement”). The Partnership shall furnish to the Purchasers at the Closing an opinion of Vinson & Elkins L.L.P., counsel for the Partnership, addressed to the Purchasers and dated the Closing Date in form
satisfactory to the Purchasers, stating that: 
 (i) Each of the Partnership, the General Partner and the subsidiaries of the Partnership
listed on Schedule I hereto (the “Domestic Subsidiaries”) is validly existing and in good standing under the laws of its jurisdiction of formation. Each of the Partnership, the General Partner and the Domestic Subsidiaries
has all requisite corporate, limited liability company or partnership power and authority, as applicable, under the laws of its jurisdiction of formation necessary to own or lease its properties and to conduct its business, in each case as described
in the Partnership SEC Documents. The Partnership, the General Partner and the Domestic Subsidiaries are each duly qualified to do business and are each in good standing in each jurisdiction listed on Schedule I. 

(ii) Except as have been waived or satisfied, there are no preemptive rights or other rights to subscribe for or to purchase, nor any
restriction upon the voting or transfer of, any interests in the Partnership pursuant to the Organizational Documents of the Partnership or any agreement, instrument or other document filed as an exhibit to the Partnership SEC Documents. There are
no securities or instruments filed as an exhibit to the Partnership SEC Documents containing anti-dilution or similar provisions that will be triggered by the issuance of the Securities. 

(iii) The Purchased Units to be issued and sold to the Purchasers by the Partnership pursuant to the Purchase Agreement and the limited
partner interests represented thereby have been duly authorized in accordance with the Partnership Agreement and, when issued and delivered to the Purchasers against payment therefor in accordance with the terms of the Purchase Agreement, will be
validly issued in accordance with the terms of the Partnership Agreement, fully paid and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the Delaware LP Act). 

(iv) Assuming the distribution of the PIK Units is properly authorized by the board of directors of the General Partner and that the PIK Units
are issued in accordance with the terms of the Partnership Agreement, the PIK Units will be duly authorized, validly issued, fully paid and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the
Delaware LP Act) and, except pursuant to applicable law, the Partnership Agreement or as provided on Schedule II hereto, will be free of any liens, charges or preemptive or similar rights contained in the Partnership Agreement or any
agreement, instrument or other documents filed as an exhibit to the Partnership SEC Documents. 
 (v) The Conversion Units and the
Additional Conversion Units have been duly authorized by the General Partner on behalf of the Partnership pursuant to the Partnership Agreement and, when issued upon conversion of the Purchased Units and the PIK Units in accordance with the

  
 Exhibit A 

 
terms of the Partnership Agreement, will be validly issued, fully paid (to the extent required by applicable law and the Partnership Agreement) and nonassessable (except as such nonassessability
may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act). 
 (vi) No consent, approval, authorization, filing with or
order of any federal or Delaware court, Governmental Authority or body having jurisdiction over the Partnership is required for the issuance and sale by the Partnership of the Purchased Units, the execution, delivery and performance by the
Partnership of the Transaction Documents, or the consummation of the transactions contemplated by the Transaction Documents, except (i) as may be required in connection with the Partnership’s obligations under the Registration Rights
Agreement to register the resale of the Conversion Units and the Additional Conversion Units under the Securities Act, (ii) those that have been obtained, (iii) as may be required under state securities or “Blue Sky” laws, as to
which we do not express any opinion, or (iv) such that the failure to obtain would not reasonably be expected to have a Material Adverse Effect. 

(vii) Assuming the accuracy of the representations and warranties of the Purchasers and the Partnership contained in the Purchase Agreement,
the offer, issuance and sale of the Purchased Units and the PIK Units by the Partnership to the Purchasers solely in the manner contemplated by the Purchase Agreement are, and the issuance and delivery of the Conversion Units and the Additional
Conversion Units will be, exempt from the registration requirements of the Securities Act; provided, however, that we express no opinion as to any subsequent sale or resale of the Purchased Units, the PIK Units, the Conversion Units or
the Additional Conversion Units. 
 (viii) The Partnership is not an “investment company” as such term is defined in the
Investment Company Act of 1940, as amended. 
 (ix) None of the offering, issuance or sale by the Partnership of the Purchased Units or the
execution, delivery and performance of the Transaction Documents by the Partnership or the General Partner, as the case may be, or the consummation of the transactions contemplated thereby will result in a breach or violation of, or constitute a
default (or an event which, with the giving of notice or lapse of time or both, constitutes or would constitute a default) under, or give rise to any right of termination, cancellation or acceleration under (A) the Organizational Documents of
the Partnership or the General Partner, as the case may be, (B) any agreement filed as an exhibit to the Partnership SEC Documents, except for the Credit Facilities, or (C) the Delaware LP Act or U.S. federal law or any applicable law of
the State of New York, which in the case of clauses (B) or (C) would be reasonably expected to have a Material Adverse Effect. 

(x) Each of Transaction Documents has been duly authorized and validly executed and delivered by the Partnership or the General Partner, as
the case may be, and the Partnership Agreement constitutes a valid and binding obligation of the General Partner, enforceable against the General Partner in accordance with its terms, except insofar as the enforceability thereof may be limited by
(A) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity (regardless of
whether such principles are considered in a proceeding in equity or at law) and (B) public policy, applicable law relating to 

  
 Exhibit A 

 
fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. The Partnership and the General Partner each has the requisite power and authority to execute, deliver
and perform all of its obligations under the Transaction Documents, including, without limitation, the issuance of the Securities in accordance with the terms thereof.
