applicable laws and the listing requirements of the New York Stock Exchange (the “NYSE”), as applicable, reasonably accounting for Independent Directors and required committee positions), one of whom shall be the Chief Executive
Officer, initially two of whom, and, by the Independence Deadline, three of whom shall be Independent Directors designated pursuant to Section 2(a)(ii) below, and the remainder of which shall be designated pursuant to

“Stockholder” and their Stockholder Percentage shall be aggregated for purposes of Section 2(a)(i) below. 

(i)    For so long as each of the Stockholders holds the corresponding Stockholder Percentage set forth in
the table below, the Company shall, and the Stockholders shall take all Necessary Action to, include in the slate of nominees recommended by the Board for election as directors at each applicable annual or special meeting of shareholders at which
directors are to be elected that aggregate number of Directors set forth opposite the range of its Stockholder Percentage:

 (ii)    The nomination of Independent Directors to include in the slate of
nominees recommended by the Board for election as directors at each applicable annual or special meeting of stockholders at which directors are to be elected will be the responsibility of the full Board. 

  
 5 

 (b)    Decrease in Directors. Upon any decrease in the number of
directors that a Stockholder is entitled to designate for nomination to the Board, such Stockholder shall take all Necessary Action to cause the appropriate number of Directors designated by such Stockholder to offer to tender their resignation,
effective as of the Company’s next annual meeting. If such resignation is accepted by the Board, the Company and the Stockholders shall take all Necessary Action to cause the authorized size of the Board to be reduced accordingly. For the
avoidance of doubt, any Director resigning pursuant to this Section 2(b) shall be permitted to continue serving as a Director until the Company’s next annual meeting. 

(c)    Removal; Vacancies. Except as provided in Section 2(b), and subject to the

vacancy to be filled by any such designee, to the extent that election or appointment of such designee to the Board would result in a number of directors designated by such Stockholder in excess of the number of directors that such Stockholder is
then entitled to designate for membership on the Board pursuant to this Agreement. 
 (d)    Additional
Directors. For so long as any Stockholder has the right to designate at least one director for nomination under this Agreement, the Company will take all Necessary Action to ensure that the number of directors serving on the Board shall not
exceed seven; provided, that the number of directors may be increased if necessary to satisfy the minimum requirements of applicable laws and the listing requirements of the NYSE, as applicable, reasonably accounting for Independent Directors
and required committee positions. 
 (e)    Voting Agreement. Each of the Company and the Stockholders agrees not
to take any actions that would affect the provisions of this Agreement and the intention of the Parties with respect to the composition of the Board as herein stated. Each Stockholder agrees to cast all votes to which such Stockholder is entitled in
respect of its Company Shares, whether at any annual or special meeting, by written consent or otherwise, so as to cause to be elected to the Board those individuals designated in accordance with this Section 2 and to
otherwise effect the intent of this Section 2. Each Stockholder agrees not to take action to remove each other’s director nominees from office pursuant to Section 5.6 of the Certificate of Incorporation unless
such removal is for cause. 
 (f)    This Section 2 shall terminate automatically (without any
action by any Party hereto) as to each Stockholder upon the later of (i) the time at which such Stockholder no longer has the right to designate an individual for nomination to the Board under this Agreement and (ii) the time at which the
Stockholders collectively cease to hold in aggregate at least fifty percent (50%) of the outstanding shares of Common Stock. 

  
 6 

 3.    Covenants. 

(a)    For so long as any Stockholder is entitled to designate a Director pursuant to Section 2,
the Company shall: 
 (i)    reimburse the members of the Board for reasonable and documented expenses
that are incurred as a result of serving as a Director, including all reasonable and documented out-of-pocket expenses incurred in connection with their attendance at
meetings of the Board and any committees thereof, including without limitation, travel, lodging and meal expenses. The Company shall also reimburse newly added members of the Board for travel expenses relating to orientation, and each member of the
Board for the reasonable expenses of attendance at one external training program per year; 

(ii)    execute and deliver to each initial Director serving as a director of the Company as of the
Effective Time, an Indemnification Agreement, and from and after the date hereof, simultaneously with any person becoming a Director, the Company shall execute and deliver to each such Director an Indemnification Agreement dated the date such
Director becomes a director of the Company; and 
 (iii)    obtain and maintain customary director and
officer indemnity insurance on commercially reasonable terms. 
 4.    Miscellaneous. 

(a)    Termination. Other than with respect to Section 4(b), which shall survive until
such time as waived or revoked in writing by the Stockholder that is a beneficiary of the obligations set forth in such provision, and with respect to Section 2, which will terminate as described in
Section 2(f), this Agreement will terminate in its entirety and will have no further force or effect at such time when no Stockholder has a Stockholder Percentage greater than or equal to 10%. 

(b)    Indemnification Priority. The Company hereby acknowledges that, in addition to the rights provided to each
Director or other indemnified person covered by any such indemnity insurance policy (any such Person, an “Indemnitee”) or the indemnification agreements that such Indemnitees shall enter into with the Company upon the closing of the
IPO Transactions and thereafter from time to time (collectively, the “Indemnification Agreements”), the Indemnitees may have certain rights to indemnification, advancement of expenses or insurance provided by one of the
Stockholders, as the case may be, or one or more of its respective Affiliates (excluding the Company and its Subsidiaries) now or hereafter (with respect to the Quintana Group or the Archer Group, as applicable, the “Partner
Indemnitors”). Notwithstanding anything to the contrary in any of the Indemnification Agreements or this Agreement, the Company hereby agrees that, to the fullest extent permitted by law, with respect to its indemnification and advancement
obligations to the Indemnitees under the Indemnification Agreements, this Agreement or otherwise, the Company (i) is the indemnitor of first resort (i.e., its and its insurers’ obligations to advance expenses and to indemnify the
Indemnitees are primary and any obligation of the Partner Indemnitors or their insurers to advance expenses or to 

  
 7 

 
provide indemnification for the same expenses or liabilities incurred by any of the Indemnitees is secondary and excess), (ii) shall be required to advance the full amount of expenses
incurred by each Indemnitee and shall be liable for the full amount of all losses, liabilities, damages, deficiencies, fines and assessments, claims, judgments, awards, settlements, demands, offsets, costs or expenses (including without limitation,
interest, penalties, court costs, arbitration costs and fees, costs of investigation, witness fees, fees and expenses of outside attorneys, investigators, expert witnesses, accountants and other professionals, and any federal, state, local or
foreign tax imposed as a result of actual or deemed receipt of any payments by the Indemnitee pursuant to this Agreement) of each Indemnitee or on his, her or its behalf to the extent legally permitted and as required by this Agreement and the
Indemnification Agreements, without regard to any rights such Indemnitees may have against the Partner Indemnitors or their insurers, and (iii) irrevocably waives and relinquishes, and releases the Partner Indemnitors and such insurers from,
any and all claims against the Partner Indemnitors or such insurers for contribution, subrogation or any other recovery of any kind in respect thereof. In furtherance and not in limitation of the foregoing, the Company agrees that in the event that
any Partner Indemnitor or its insurer should advance any expenses or make any payment to any Indemnitee for matters subject to advancement or indemnification by the Company pursuant to this Agreement or otherwise, the Company shall promptly
reimburse such Partner Indemnitor or insurer and that such Partner Indemnitor or insurer shall be subrogated to all of the claims or rights of such Indemnitee under the Indemnification Agreements, this Agreement or otherwise, including to the
payment of expenses in an action to collect. The Company agrees that any Partner Indemnitor or insurer thereof not a party hereto shall be an express third party beneficiary of this Section 4(b), and as such, will be able
to enforce such clause according to its terms as if it were a party hereto. Nothing contained in the Indemnification Agreements is intended to limit the scope of this Section 4(b), the other terms set forth in this
Agreement or the rights of the Partner Indemnitors or their insurers hereunder. 
 (c)    Entire Agreement. This
Agreement, together with any Indemnification Agreement, constitutes the entire agreement among the Parties and supersedes any prior understandings, agreement or representations by or between the Parties, written or oral, to the extent they relate in
any way to the subject matter hereof. 
 (d)    Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the Parties and their respective heirs, executors, administrators, successors, legal representatives and permitted assigns. This Agreement may not be assigned by any party hereto without the prior written consent of each of
the Stockholders, which consents shall be sufficient for assignment. Any purported assignment of this Agreement in violation of the immediately preceding sentence shall be null and void ab initio.

 (g)    Governing Law; Submission to Jurisdiction. This Agreement shall
be governed by and construed in accordance with the laws of the State of Delaware. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in the Delaware Chancery
Courts located in Wilmington, Delaware, or, if such court shall not have jurisdiction, any federal court of the United States of America or other Delaware state court located in Wilmington, Delaware, and appropriate appellate courts therefrom, and
each Party irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding. Service of process, summons, notice or other document by mail to such Party’s address set forth herein shall be effective
service of process for any suit, action or other proceeding brought in any such court. The Parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or any proceeding in such courts, and irrevocably waive
and agree not to plead or claim in any such court that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. 

(h)    Amendments and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall
be in writing and signed by each of the Parties. No waiver by any Party of any default, misrepresentation or breach of warranty or covenant hereunder, regardless of whether intentional, shall be deemed to extend to any prior or subsequent default,
misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. 

(i)    Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in
any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. 

(j)    No Third Party Beneficiaries. Except for the indemnification provisions, this Agreement shall not confer any
rights or remedies upon any Person other than the Parties and their respective successors and permitted assigns. 

(k)    Specific Performance. It is hereby agreed and acknowledged that it will be impossible to measure in money
the damages that would be suffered if the Parties fail to comply with any of the obligations herein imposed on them and that, in the event of any such failure, an aggrieved Person will be irreparably damaged and will not have an adequate remedy at
law. Any such party shall, therefore, be entitled (in addition to any other remedy to which such party may be entitled at law or in equity) to injunctive relief, including specific performance, to enforce such obligations, without the posting of any
bond and if any action should be brought in equity to enforce any of the provisions of this Agreement, none of the Parties shall raise the defense that there is an adequate remedy at law. 

(l)    Subsequent Acquisition of Shares. Any equity securities of the Company acquired subsequent to the date
hereof by a Stockholder shall be subject to the terms and conditions of this Agreement and such shares shall be considered to be “Company Shares” as such term is used herein for purposes of this Agreement. 

  
 11 

 (m)    Sharing of Information. To the extent permitted by antitrust,
competition or any other applicable law, each Stockholder agrees and acknowledges that the directors designated by each Stockholder may share confidential, non-public information (the “Confidential
Information”) about the Company and its subsidiaries with the Quintana Group, the Archer Group, and Geveran, respectively. Each Stockholder recognizes that it, or its Affiliates, has acquired or will acquire Confidential Information the use
or disclosure of which could cause the Company substantial loss and damages that could not be readily calculated and for which no remedy at law would be adequate. Accordingly, each Stockholder covenants and agrees with the Company that it will not
(and will cause its respective Affiliates not to) at any time, except with the prior written consent of the Company, directly or indirectly, disclose any Confidential Information known to it, unless (i) such information becomes known to the
public through no fault of such Stockholder, (ii) disclosure is required by applicable law or court of competent jurisdiction or requested by a governmental agency, provided, that such Stockholder promptly notifies the Company of such
disclosure and takes reasonable steps to minimize the extent of any such required disclosure, (iii) such information was available or becomes available to such Stockholder before, on or after the date hereof, without restriction, from a source
(other than the Company) without any breach of duty to the Company or (iv) such information was independently developed by the Stockholder or its representatives without the use of Confidential Information. Notwithstanding anything herein to
the contrary, nothing in this Agreement shall prohibit a Stockholder from disclosing Confidential Information to any Affiliate, representative, limited partner, member or shareholder of such Stockholder; provided, that such Shareholder shall
be responsible for any breach of this Section 4(m) by any such person. 

(n)    Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In
the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the
authorship of any of the provisions of this Agreement. Any reference to any federal, state, local or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. The
word “including” shall mean “including, without limitation,” and the word “or” is not exclusive, and has the inclusive meaning represented by the phrase “and/or.” All personal pronouns used in this Agreement,
whether used in the masculine, feminine or neuter gender, shall include all other genders; the singular shall include the plural, and vice versa. All references herein to Schedules, Articles, Sections or subdivisions thereof shall refer to the
corresponding Schedules, Articles, Sections or subdivisions thereof of this Agreement unless specific reference is made to such articles, sections or subdivisions of another document or instrument, and all captions of the articles, sections or
subsections thereof appearing in this Agreement are inserted only as a matter of convenience and in no way define, limit, construe or describe the scope or extent of such articles, sections or subsections, or in any way affect this Agreement. The
terms “herein,” “hereby,” “hereunder,” “hereof,” “hereinafter,” and other equivalent words refer to this Agreement in its entirety and not solely to the particular portion of the Agreement in which
such word is used. The words “shall” and “will” are used interchangeably throughout this Agreement and shall accordingly be given the same meaning, regardless of which word is used. References to a Party shall include its
permitted successors and assigns. All references to prices, values or monetary amounts refer to United States dollars. Each certificate delivered pursuant to this Agreement shall be deemed a part hereof, and any

  
 12 

 
representation, warranty or covenant herein referenced or affirmed in such certificate shall be treated as a representation, warranty or covenant given in the corresponding section hereof on the
date of such certificate. Additionally, any representation, warranty or covenant made in any such certificate shall be deemed to be made herein. Except as otherwise expressly provided herein, all terms of an accounting or financial nature shall be
construed in accordance with GAAP.

2.    Shelf Registration; Shelf Takedowns. 

(a)    At such time as the Partnership shall have qualified for the use of a Registration Statement on Form
S-3 or the then appropriate form for an offering to be made on a delayed or continuous basis pursuant to Rule 415 under the Securities Act or any successor rule thereto (a “Shelf Registration
Statement”), each holder of Registrable Securities shall have the right to request the registration under the Securities Act of all or any portion of their Registrable Securities for an offering on a delayed or continuous basis pursuant to
Rule 415 under the Securities Act or any successor rule thereto (a “Shelf Registration”). Such request for a Shelf Registration shall specify the number of Registrable Securities requested to be included in the Shelf
Registration. Upon receipt of any such request, the QES Parties shall cause the Partnership to promptly (but in no event later than 5 Business Days following receipt thereof) deliver notice of such request to all other holders of Registrable
Securities who shall then have 10 days from the date such notice is given to notify the Partnership in writing of their desire to be included in such registration. The QES Parties shall cause the Partnership to prepare and file with the Commission a
Shelf Registration Statement covering all of the Registrable Securities that the holders thereof have requested to be included in such 

  
 4 

 
Shelf Registration within 45 days after the date on which the initial request is given and shall use commercially reasonable efforts to cause such Shelf Registration Statement to be declared
effective by the Commission as soon as practicable thereafter. Each Shelf Registration Statement shall provide for the resale pursuant to any method or combination of methods legally available to, and requested by, the holders of Registrable
Securities. After the filing of a Shelf Registration Statement, and until all Registrable Securities covered by such Shelf Registration Statement have ceased to be Registrable Securities, the Partnership shall use its commercially reasonable efforts
to ensure that such Shelf Registration Statement remains continuously effective. 
 (b)    At any time
that the Shelf Registration Statement is effective, if a holder of Registrable Securities covered by such Shelf Registration Statement delivers a notice to the Partnership (a “Shelf Takedown Notice”) stating that the holder intends
to effect an offering of all or part of its Registrable Securities included in such Shelf Registration Statement (a “Shelf Takedown”) and the Partnership is eligible to use such Shelf Registration Statement for such Shelf Takedown,
then the QES Parties shall cause the Partnership to take all actions reasonably required, including amending or supplementing such Shelf Registration Statement, to enable such Registrable Securities to be offered and sold as contemplated by such
Shelf Takedown Notice. Each Shelf Takedown Notice shall specify the number of Registrable Securities to be offered and sold under the Shelf Takedown. Upon receipt of a Shelf Takedown Notice, the Partnership shall promptly (but in no event later than
2 Business Days following receipt thereof) deliver notice of such Shelf Takedown Notice to all other holders of Registrable Securities who shall then have 5 Business Days from the date such notice is given to notify the Partnership in writing of
their desire to be included in such Shelf Takedown. The QES Parties shall cause the Partnership to prepare and file with the Commission a Shelf Supplement as soon as practicable after the date on which it received the Shelf Takedown Notice and, if
such Shelf Supplement is an amendment to such Shelf Registration Statement, shall use its commercially reasonable efforts to cause such Shelf Supplement to be declared effective by the Commission as soon as practicable thereafter. 

(c)    The Partnership shall not be obligated to effect any Shelf Takedown within 120 days after the
effective date of a previous Shelf Takedown in which holders of Registrable Securities were permitted to register the offer and sale under the Securities Act, and actually sold, at least 50% of the Registrable Securities requested to be included
therein. Additionally, the Partnership shall not be obligated to effect any Shelf Takedown with respect to any offering that would reasonably be expected to result in net proceeds of less than $30 million to the participating holders. The
Partnership may postpone for up to 120 days any Shelf Takedown and the filing of any Shelf Supplement if the Board determines in its reasonable good faith judgment that such Shelf Takedown would: (1) materially interfere with a significant
acquisition, corporate organization, financing, securities offering or other similar transaction involving the Partnership; (2) require premature disclosure of material information that the Partnership has a bona fide business purpose for
preserving as confidential; or (3) render the Partnership unable to materially comply with requirements under the Securities Act or Exchange Act; provided, that in such event the holders of a majority of the Registrable Securities
initiating such Shelf Takedown shall be entitled to withdraw such request and, if such request for a Shelf-Takedown is withdrawn, such Shelf-Takedown shall not count as one of the permitted Shelf-Takedowns hereunder and the Partnership shall pay all
registration expenses in connection with such registration. The Partnership may delay a Shelf Takedown hereunder only twice in any period of 12 consecutive months. 

  
 5 

 (d)    If a holder of the Registrable Securities initially
requesting a Shelf Takedown elects to distribute the Registrable Securities covered by its request in an underwritten offering, it shall so advise the Partnership as a part of their request made pursuant to Section 2(a) or
Section 2(b), and the Partnership shall include such information in its notice to the other holders of Registrable Securities. The Partnership, on the one hand, and the holders of Registrable Securities (pursuant to the
consent of the holders of a majority of the Registrable Securities proposed to be included in such Shelf Takedown), on the other, shall each select an investment banking firm to act as one of the two managing underwriters in connection with such
offering; provided, that such selection shall be subject to the consent of the other party, which consent shall not be unreasonably withheld or delayed. 

(e)    The Partnership may include in any Shelf Takedown for an underwritten offering any securities that
are not Registrable Securities on behalf of the Partnership or on behalf of a holder of Common Units that are not Registrable Securities if such holder has contractual piggyback registration rights and such securities are registered on a Shelf
Registration Statement; provided, however, that if a Shelf Takedown involves an underwritten offering and the managing underwriter of the requested Shelf Takedown advises the Partnership and the holders of Registrable Securities in
writing that in its reasonable and good faith opinion the number of Common Units proposed to be included in the Shelf Takedown, including all Registrable Securities and all other Common Units proposed to be included in such underwritten offering,
exceeds the number of Common Units that can be sold in such underwritten offering and/or the number of Common Units proposed to be included in such Shelf Takedown would adversely affect the price per unit of the Common Units proposed to be sold in
such underwritten offering, the QES Parties shall cause the Partnership to include in such Shelf Takedown (1) first, the Common Units that the holders of Registrable Securities propose to sell, and (2) second, the Common Units proposed to
be included therein by any other Persons (including Common Units to be sold for the account of the Partnership and/or other holders of Common Units) allocated among such Persons in such manner as they may agree. If the managing underwriter
determines that less than all of the Registrable Securities proposed to be sold can be included in such offering, then the Registrable Securities that are included in such offering shall be allocated pro rata among the respective holders thereof on
the basis of the number of Registrable Securities owned by each such holder. 
 3.    Piggyback Registration. 

(a)    Whenever the Partnership proposes the offer and sale of any of the Partnership’s Common Units
or other securities under the Securities Act (other than a registration (i) pursuant to a Registration Statement on Form S-8 (or other registration solely relating to an offering or sale to employees or
directors of either of the QES Parties pursuant to any employee stock plan or other employee benefit arrangement), (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a
transaction subject to Rule 145 under the Securities Act or any successor rule thereto), or (iii) in connection with any dividend or distribution reinvestment or similar plan), whether for its own account or for the account of one or more
partners of the Partnership (a “Piggyback Sale”), the Partnership shall give 

  
 6 

 
prompt written notice (in any event no later than 10 days prior to the initiation of such offer and sale) to the holders of Registrable Securities of its intention to effect such an offer and
sale and, subject to Sections 3(b) and 3(c), shall include in such an offer and sale all Registrable Securities with respect to which the Partnership has received written requests for inclusion from the holders of
Registrable Securities within 7 Business Days after the Partnership’s notice has been given to each such holder. The Partnership may postpone or withdraw such offering or sale at any time in its sole discretion. 

(b)    If a Piggyback Sale is initiated as a primary underwritten offering on behalf of the Partnership and
the managing underwriter advises the Partnership and the holders of Registrable Securities (if any holders of Registrable Securities have elected to include Registrable Securities in such Piggyback Sale) in writing that in its reasonable and good
faith opinion the number of Common Units proposed to be included in such registration or takedown, including all Registrable Securities and all other Common Units proposed to be included in such underwritten offering, exceeds the number of Common
Units that can be sold in such offering and/or that the number of Common Units proposed to be included in any such registration or takedown would adversely affect the price per unit of the Common Units to be sold in such offering, the QES Parties
shall cause the Partnership to include in such registration or takedown (i) first, the Common Units that the Partnership proposes to sell; and (ii) second, the Common Units requested to be included therein by holders of Registrable
Securities, allocated among such holders pro rata based on the number of Common Units held by each applicable holder or in such manner as they may agree. 

(c)    If a Piggyback Sale is initiated as an underwritten offering on behalf of a holder of Common Units
other than Registrable Securities, and the managing underwriter advises the Partnership in writing that in its reasonable and good faith opinion the number of Common Units proposed to be included in such registration or takedown, including all
Registrable Securities and all other Common Units proposed to be included in such underwritten offering, exceeds the number of Common Units that can be sold in such offering and/or that the number of Common Units proposed to be included in any such
registration or takedown would adversely affect the price per unit of the Common Units to be sold in such offering, the QES Parties shall cause the Partnership to include in such registration or takedown (i) first, the Common Units requested to
be included therein by the holder(s) requesting such registration or takedown; and (ii) second, the Common Units requested to be included therein by the holders of Registrable Securities and by the other holders of Common Units (other than
holders of Registrable Securities) with registration rights entitling them to participate in such underwritten offering, allocated among such holders pro rata on the basis of the number of Common Units held by each applicable holder or in such
manner as they may agree. 
 (d)    If any Piggyback Sale is initiated as a primary underwritten offering
on behalf of the Partnership, the Partnership shall select the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering. 

4.    Lock-up Agreement. Each holder of Registrable Securities agrees that
in connection with any registered offering of the Common Units or other equity securities of the Partnership, and upon the request of the managing underwriter in such offering, if, after giving effect to the disposition of Common Units in such
offering the holder of such Registrable 

  
 7 

 
Securities would continue to own at least 10% of the total number of outstanding Common Units, such holder shall not, without the prior written consent of such managing underwriter, during the
period commencing 10 days prior to the effective date of such registration and ending on the date specified by such managing underwriter (such period not to exceed 180 days without the prior written consent of a majority of the holders of
Registrable Securities to be included in such offering), (a) offer, pledge, sell, contract to sell, grant any option or contract to purchase, purchase any option or contract to sell, hedge the beneficial ownership of or otherwise dispose of,
directly or indirectly, any Common Units or any securities convertible into, exercisable for or exchangeable for Common Units (whether such units or any such securities are then owned by the holder or are thereafter acquired), or (b) enter into
any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such securities, whether any such transaction described in clause (a) or (b) above is to be settled by delivery
of Common Units or such other securities, in cash or otherwise. The foregoing provisions of this Section 4 shall not apply to sales of Registrable Securities to be included in such offering pursuant to
Section 2 or Section 3(a). Each holder of Registrable Securities agrees to execute and deliver such other agreements as may be reasonably requested by the Partnership or the managing underwriter
that are consistent with the foregoing or that are necessary to give further effect thereto. Notwithstanding anything to the contrary contained in this Section 4, each holder of Registrable Securities shall be released, pro
rata, from any lock-up agreement entered into pursuant to this Section 4 in the event and to the extent that the managing underwriter or the Partnership permit any discretionary
waiver or termination of the restrictions of any lock-up agreement pertaining to any officer, director or holders participating in the applicable offering. 

5.    Registration Procedures. If and whenever the holders of Registrable Securities request that the offer and
sale of any Registrable Securities be registered under the Securities Act or any Registrable Securities be distributed in a Shelf Takedown pursuant to the provisions of this Agreement, the QES Parties shall use their respective commercially
reasonable efforts to cause the Partnership to effect the offer and sale of such Registrable Securities under the Securities Act in accordance with the intended method of disposition thereof, and pursuant thereto the QES Parties shall cause the
Partnership as soon as reasonably practicable and as applicable to: 
 (a)    subject to
Section 2, prepare and file with the Commission a Registration Statement covering such Registrable Securities and use its commercially reasonable efforts to cause such Registration Statement to be declared effective; 

(b)    prepare and file with the Commission such amendments, post-effective amendments and supplements to
such Registration Statement and the Prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all Registrable
Securities subject thereto for a period ending on the earlier of (i) 6 months after the effective date of such Registration Statement and (ii) the date on which all the Registrable Securities subject thereto have been sold pursuant to such
Registration Statement; 
 (c)    within a reasonable time before filing such Registration Statement,
Prospectus or amendments or supplements thereto with the Commission, furnish to one counsel selected by the holders of a majority of the Registrable Securities included in such Registration Statement, Prospectus or amendments or supplements thereto
copies of such documents proposed to be filed, which documents shall be subject to the review, comment and approval of such counsel; 

  
 8 

 (d)    notify each selling holder of Registrable Securities,
promptly after the Partnership receives notice thereof, of the time when such Registration Statement has been declared effective or a supplement to any Prospectus forming a part of such Registration Statement has been filed with the Commission; 

(e)    furnish to each selling holder of Registrable Securities such number of copies of the Prospectus
included in such Registration Statement (including each preliminary Prospectus) and any supplement thereto (in each case including all exhibits and documents incorporated by reference therein) and such other documents as such seller may reasonably
request in order to facilitate the disposition of the Registrable Securities owned by such seller; 

(f)    use its commercially reasonable efforts to register or qualify such Registrable Securities under
such other securities or “blue sky” laws of such jurisdictions as any selling holder reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such holders to consummate the
disposition in such jurisdictions of the Registrable Securities owned by such holders; provided, that the Partnership shall not be required to qualify generally to do business, subject itself to general taxation or consent to general service
of process in any jurisdiction where it would not otherwise be required to do so but for this Section 5(f); 

(g)    notify each selling holder of such Registrable Securities, at any time when a Prospectus relating
thereto is required to be delivered under the Securities Act, of the happening of any event that would cause the Prospectus included in such Registration Statement to contain an untrue statement of a material fact or omit any fact necessary in order
to make the statements made therein, in light of the circumstances under which they were made, not misleading, and, at the request of any such holder, the QES Parties shall cause the Partnership to prepare a supplement or amendment to such
Prospectus so that, as thereafter delivered to the purchasers of such Registrable Securities, such Prospectus shall not contain an untrue statement of a material fact or omit to state any fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading; 
 (h)    make available for inspection by
any selling holder of Registrable Securities, any underwriter participating in any disposition pursuant to such Registration Statement and any attorney, accountant or other agent retained by any such holder or underwriter (collectively, the

show” and other customary marketing activities (including one-on-one meetings with prospective purchasers of the Registrable Securities)); 

(l)    otherwise use its commercially reasonable efforts to comply with all applicable rules and
regulations of the Commission and make available to its holders an earnings statement (in a form that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 under the Securities Act or any successor rule thereto) no later
than thirty (30) days after the end of the 12-month period beginning with the first day of the Partnership’s first full fiscal quarter after the effective date of such Registration Statement, which
earnings statement shall cover said 12-month period, and which requirement will be deemed to be satisfied if the Partnership timely files complete and accurate information on Forms 10-K, 10-Q and 8-K under the Exchange Act and otherwise complies with Rule 158 under the Securities Act or any successor rule thereto;

 (m)    furnish to each selling holder of Registrable Securities and each underwriter, if any, with
(i) a written legal opinion of the Partnership’s outside counsel, dated the closing date of the offering, in form and substance as is customarily given in opinions of registrants’ counsel to underwriters in underwritten registered
offerings; and (ii) on the date of the applicable Prospectus, on the effective date of any post-effective amendment to the applicable Registration Statement and at the closing of the offering, dated the respective dates of delivery thereof, a
“comfort” letter signed by the Partnership’s independent certified public accountants in form and substance as is customarily given in accountants’ letters to underwriters in underwritten registered offerings; 

(n)    without limiting Section 5(f), use its commercially reasonable efforts to
cause such 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 holders of such Registrable
Securities to consummate the disposition of such Registrable Securities in accordance with their intended method of distribution thereof; 

(o)    notify the holders of Registrable Securities promptly of any request by the Commission for the
amending or supplementing of such Registration Statement or Prospectus or for additional information; 

(p)    advise the holders of Registrable Securities, promptly after it shall receive notice or obtain
knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its commercially reasonable

 10 

 (q)    cooperate with the holders of the Registrable
Securities to facilitate the timely preparation and delivery of certificates representing the Registrable Securities to be sold pursuant to such Registration Statement free of any restrictive legends and representing such number of Common Units and
registered in such names as the holders of the Registrable Securities may reasonably request a reasonable period of time prior to sales of Registrable Securities pursuant to such Registration Statement; provided, that the Partnership may
satisfy its obligations hereunder without issuing physical stock certificates through the use of the facilities of The Depository Trust Company (“DTC”); 

(r)    not later than the effective date of such Registration Statement, provide a CUSIP number for all
Registrable Securities and provide the applicable transfer agent with printed certificates for the Registrable Securities which are in a form eligible for deposit with DTC; provided, that the Partnership may satisfy its obligations hereunder
without issuing physical stock certificates through the use of the facilities of DTC; 
 (s)    take no
direct or indirect action prohibited by Regulation M under the Exchange Act; provided, that, to the extent that any prohibition is applicable to the Partnership, the Partnership will take all commercially reasonable action to make any such
prohibition inapplicable; and 
 (t)    otherwise use its commercially reasonable efforts to take all
other steps necessary to effect the registration of such Registrable Securities contemplated hereby. 

6.    Expenses. All expenses (other than Selling Expenses) incurred by the Partnership in complying with its
obligations pursuant to this Agreement and in connection with the registration and disposition of Registrable Securities shall be paid by the Partnership, including, without limitation, all (i) registration and filing fees (including, without
limitation, any fees relating to filings required to be made with, or the listing of any Registrable Securities on, any securities exchange or over-the-counter trading
market on which the Registrable Securities are listed or quoted); (ii) underwriting expenses (other than fees, commissions or discounts); (iii) expenses of any audits incident to or required by any such registration; (iv) fees and
expenses of complying with securities and “blue sky” laws (including, without limitation, fees and disbursements of counsel for the Partnership in connection with “blue sky” qualifications or exemptions of the Registrable
Securities) of any domestic jurisdictions, reasonably requested by the holders of Registrable Securities; (v) printing expenses; (vi) messenger, telephone and delivery expenses; (vii) fees and expenses of the Partnership’s
counsel and accountants; (viii) Financial Industry Regulatory Authority, Inc. filing fees (if any); and (ix) reasonable fees and expenses of one counsel for the holders of Registrable Securities participating in such registration as a
group (selected by the holders of a majority of the Registrable Securities being sold in any offering). In addition, the Partnership shall be responsible for all of its internal expenses incurred in connection with the consummation of the
transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties) and the expense of any annual audits. All Selling Expenses relating to the
offer and sale of Registrable Securities registered under the Securities Act pursuant to this Agreement shall be borne and paid by the holders of such Registrable Securities, in proportion to the number of Registrable Securities included in such
registration for each such holder.

 7.    Indemnification. 

(a)    The Partnership shall indemnify and hold harmless, to the fullest extent permitted by law, each
holder of Registrable Securities, such holder’s officers, directors, managers, members, partners, stockholders, employees and Affiliates, each underwriter, broker or any other Person acting on behalf of such holder of Registrable Securities and
each other Controlling Person, if any, who controls any of the foregoing Persons, against all losses, claims, actions, damages, liabilities and expenses, joint or several, to which any of the foregoing Persons may become subject under the Securities
Act or otherwise, insofar as such losses, claims, actions, damages, liabilities or expenses arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, Prospectus, preliminary
Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule thereto) or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein
or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus, in light of the circumstances under which they were made) not misleading; and shall reimburse such Persons for any legal or
other expenses reasonably incurred by any of them in connection with investigating or defending any such loss, claim, action, damage or liability, except insofar as the same are caused by or contained in any information furnished in writing to the
Partnership by such holder expressly for use therein or by such holder’s failure to deliver a copy of the Registration Statement, Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or
any successor rule thereto) or any amendments or supplements thereto (if the same was required by applicable law to be so delivered) after the Partnership has furnished such holder with a sufficient number of copies of the same prior to any written
confirmation of the sale of Registrable Securities. This indemnity shall be in addition to any liability the Partnership may otherwise have. 

(b)    In connection with any registration in which a holder of Registrable Securities is participating,
each such holder shall furnish to the Partnership in writing such information as the Partnership reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify and
hold harmless, the Partnership, each director of the Partnership, each officer of the Partnership who shall sign such Registration Statement, each underwriter, broker or other Person acting on behalf of the holders of Registrable Securities and each
Controlling Person who controls any of the foregoing Persons against any losses, claims, actions, damages, liabilities or expenses resulting from any untrue or alleged untrue statement of material fact contained in the Registration Statement,
Prospectus, preliminary Prospectus, free writing prospectus (as defined in Rule 405 under the Securities Act or any successor rule thereto) or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus, in light of the circumstances under which they were made) not misleading, but only to the
extent that such untrue statement or omission is contained in any information so furnished in writing by such holder; provided, that the obligation to indemnify shall be several, not joint and several, for each holder and shall not exceed an
amount equal to the net proceeds (after underwriting fees, commissions or discounts) actually received by such holder from the sale of Registrable Securities pursuant to such Registration Statement. This indemnity shall be in addition to any
liability the selling holder may otherwise have. 

  
 12 

 (c)    Promptly after receipt by an indemnified party of
notice of the commencement of any action involving a claim referred to in this Section 7, such indemnified party shall, if a claim in respect thereof is made against an indemnifying party, give written notice to the latter
of the commencement of such action. The failure of any indemnified party to notify an indemnifying party of any such action shall not (unless such failure shall have a material adverse effect on the indemnifying party) relieve the indemnifying party
from any liability in respect of such action that it may have to such indemnified party hereunder. In case any such action is brought against an indemnified party, the indemnifying party shall be entitled to participate in and to assume the defense
of the claims in any such action that are subject or potentially subject to indemnification hereunder, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and after written notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred
by the indemnified party in connection with the defense thereof; provided, that, if (i) any indemnified party shall have reasonably concluded that there may be one or more legal or equitable defenses available to such indemnified party
which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity provided hereunder, or (ii) such action seeks
an injunction or equitable relief against any indemnified party or involves actual or alleged criminal activity, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party without such
indemnified party’s prior written consent (but, without such consent, shall have the right to participate therein with counsel of its choice) and such indemnifying party shall reimburse such indemnified party and any Controlling Person of such
indemnified party for that portion of the fees and expenses of any counsel retained by the indemnified party which is reasonably related to the matters covered by the indemnity provided hereunder. If the indemnifying party is not entitled to, or
elects not to, assume the defense of a claim, it shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any
indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. In such instance, the conflicting indemnified parties shall have a right to retain one separate
counsel chosen by the holders of a majority of the Registrable Securities included in the registration, at the expense of the indemnifying party. 

(d)    If the indemnification provided for hereunder is held by a court of competent jurisdiction to be
unavailable to an indemnified party with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or
payable by such indemnified party as a result of such loss, claim, damage, liability or action 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 loss, claim, damage, liability or action as well as any other relevant equitable considerations; provided, that the maximum amount of liability in respect of such
contribution 

  
 13 

 
shall be limited, in the case of each holder of Registrable Securities, to an amount equal to the net proceeds (after underwriting fees, commissions or discounts) actually received by such seller
from the sale of Registrable Securities effected pursuant to such registration. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, whether the violation of the Securities Act or any other similar federal
or state securities laws or rule or regulation promulgated thereunder applicable to the Partnership and relating to action or inaction required of the Partnership in connection with any applicable registration, qualification or compliance was
perpetrated by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties agree that it would not be just and
equitable if contribution pursuant hereto were determined by pro rata allocation or by any other method or allocation which does not take account of the equitable considerations referred to herein. No Person guilty or liable of fraudulent
misrepresentation within the meaning of Section 11(f) of the Securities Act shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

8.    Participation in Underwritten Registrations. No Person may participate in any registration hereunder that is
underwritten unless such Person (a) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Person or Persons entitled hereunder to approve such arrangements and (b) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 

9.    Rule 144 Compliance. With a view to making available to the holders of Registrable Securities the benefits of
Rule 144 and any other rule or regulation of the Commission that may at any time permit a holder to sell securities of the Partnership to the public without registration, after the Registration Date, the QES Parties shall cause the Partnership to:

 (a)    use commercially reasonable efforts to make and keep public information available, as those
terms are understood and defined in Rule 144, at all times after the Registration Date; 
 (b)    use
commercially reasonable efforts to 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 any time after the Registration Date; and 

(c)    furnish to any holder so long as the holder owns Registrable Securities, promptly upon request,
(i) a written statement by the Partnership as to its compliance with the reporting requirements of Rule 144 and of the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Partnership,
(iii) such other reports and documents so filed or furnished by the Partnership as such holder may reasonably request in connection with the sale of Registrable Securities without registration and (iv) the opinion of the Partnership’s
outside counsel, in form and substance reasonably acceptable to the transfer 

  
 14 

 
agent for the Common Units, relating to such matters as such transfer agent may reasonably request in connection with the removal of any restrictive legends contained on such Common Units. 

10.    Recapitalization, Exchanges, Etc. Affecting the Securities. The provisions of this Agreement shall apply to
the full extent set forth herein with respect to any and all Common Units of the Partnership or any successor or assign of the Partnership (whether by merger, consolidation, sale of assets or otherwise) that may be issued in respect of, in exchange
for or in substitution of, the Registrable Securities or Warrants, and shall be appropriately adjusted for combinations, splits, recapitalizations, pro rata distributions and the like occurring on or after the date of this Agreement. 

11.    Termination. This Agreement shall terminate and be of no further force or effect when there shall no longer
be any Registrable Securities or Warrants outstanding; provided, that the provisions of Section 6 and Section 7 shall survive any such termination. 

12.    Notices. All notices, requests, demands and other communications under this Agreement shall be in writing
and shall be deemed to have been duly given or made as follows: (a) if sent by registered or certified mail in the United States return receipt requested, upon receipt; (b) if sent by nationally recognized overnight air courier, one
(1) Business Day after mailing; (c) if sent by facsimile transmission, when transmitted and receipt is confirmed; (d) if sent by e-mail transmission, with a copy sent on the same day in the
manner provided in Section 12(a), Section 12(b) or Section 12(c), when transmitted and receipt is confirmed; and (v) if otherwise actually personally delivered, when
delivered. All communications to the Parties shall be sent to the following addresses (or any other address that any such Party may designate by written notice to the other Parties):

 13.    Entire Agreement. This Agreement, together with the Warrant
Purchase Agreement and the Warrant Agreement, and any related exhibits and schedules thereto, constitutes the sole and entire agreement of the parties to this Agreement with respect to the subject matter contained herein, and supersedes all prior
and contemporaneous understandings and agreements, both written and oral, with respect to such subject matter. Notwithstanding the foregoing, in the event of any conflict between the terms and provisions of this Agreement and those of the Warrant
Purchase Agreement or the Warrant Agreement, the terms and conditions of this Agreement shall control. 

14.    Successor and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties
hereto and their respective successors and permitted assigns. The QES Parties, collectively, may assign this Agreement at any time in connection with a sale or acquisition of the Partnership, whether by merger, consolidation, sale of all or
substantially all of the Partnership’s assets, or similar transaction, without the consent of the Investors and QES Holdco; provided, that the successor or acquiring Person agrees in writing to assume all of the QES Parties’ rights
and obligations under this Agreement. Each of the Investors and QES Holdco may assign its rights hereunder to any purchaser or transferee of Registrable Securities or Warrants; provided, that such purchaser or transferee shall, as a condition
to the effectiveness of such assignment, be required to execute a counterpart to this Agreement agreeing to be treated as an Investor whereupon such purchaser or transferee shall have the benefits of, and shall be subject to the restrictions
contained in, this Agreement as if such purchaser or transferee was originally included in the definition of an Investor herein and had originally been a party hereto. 

15.    No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their
respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement;
provided, however, the parties hereto hereby acknowledge that the Persons set forth in Section 7 are express third-party beneficiaries of the obligations of the parties hereto set forth in
Section 7. 
 16.    Headings. The headings in this Agreement are for reference only
and shall not affect the interpretation of this Agreement. 
 17.    Amendments and Waivers. No amendment of any
provision of this Agreement shall be valid unless the same shall be in writing and signed by each of the parties hereto. No waiver by any party hereto of any default, misrepresentation or breach of warranty or covenant hereunder, regardless of
whether intentional, shall be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. 

18.    Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in
any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. 

19.    Remedies. Each holder of Registrable Securities, in addition to being entitled to exercise all rights
granted by law, including recovery of damages, shall be entitled to specific 

  
 17 

 
performance of its rights under this Agreement. The Partnership acknowledges that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the
provisions of this Agreement and the Partnership hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. 

20.    Governing Law; Submission to Jurisdiction. This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in the Delaware Chancery Courts located in Wilmington, Delaware, or,
if such court shall not have jurisdiction, any federal court of the United States of America or other Delaware state court located in Wilmington, Delaware, and appropriate appellate courts therefrom, and each Party irrevocably submits to the
exclusive jurisdiction of such courts in any such suit, action or proceeding. Service of process, summons, notice or other document by mail to such Party’s address set forth herein shall be effective service of process for any suit, action or
other proceeding brought in any such court. The Parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or any proceeding in such courts, and irrevocably waive and agree not to plead or claim in any
such court that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. 

21.    Waiver of Jury Trial. Each party acknowledges and agrees that any controversy which may arise under this
Agreement is likely to involve complicated and difficult issues and, therefore, each such party irrevocably and unconditionally waives any right it may have to a trial by jury in respect of any legal action arising out of or relating to this
Agreement or the transactions contemplated hereby. Each party to this Agreement certifies and acknowledges that (a) no representative of any other party has represented, expressly or otherwise, that such other party would not seek to enforce
the foregoing waiver in the event of a legal action, (b) such party has considered the implications of this waiver, (c) such party makes this waiver voluntarily, and (d) such party has been induced to enter into this Agreement by,
among other things, the mutual waivers and certifications in this Section 21. 

22.    Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original but
which together shall constitute one and the same instrument. A signed copy of this Agreement delivered by facsimile, e-mail or other means of electronic transmission shall be deemed to have the same legal
effect as delivery of an original signed copy of this Agreement. 
 23.    Further Assurances. Each of the
parties to this Agreement shall, and shall cause their controlled Affiliates to, execute and deliver such additional documents, instruments, conveyances and assurances and take such further actions as may be reasonably required to carry out the
provisions hereof and to give effect to the transactions contemplated hereby.
