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:

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.
