Properties may be bound or (d) result in or require the creation or imposition of any Lien upon or with respect to any of the Properties now owned or hereafter acquired by USWS or any of its
Subsidiaries, except in the case of clauses (a), (c) and (d) where any such conflict, violation, default, breach, termination, cancellation, failure to receive consent, approval or notice, or acceleration

power and authority to execute, deliver and perform its obligations under the Basic Documents, and the execution, delivery and performance by USWS of the Basic Documents has been duly authorized by all necessary action on the part of USWS. All
corporate action required to be taken by the USWS for the authorization, issuance, sale and delivery of the Purchased Securities, the execution, delivery and performance of the Basic Documents by the USWS, and the consummation of the transactions

and validly authorized, executed and delivered by USWS and will constitute the legal, valid and binding obligations of USWS, enforceable in accordance with their terms, except as such enforceability may be limited by bankruptcy, insolvency,
fraudulent transfer and similar laws affecting creditors’ rights generally or by general principles of equity and except as the rights to indemnification may be limited by applicable law. No approval from the holders of USWS’s Class A
Common Stock, Class B Common Stock, Series A Preferred Stock or Warrants is required in connection with USWS’s issuance and sale of the Purchased Securities to the Purchasers.

office of the Secretary of State of Delaware or the filing with the SEC of a Current Report on Form 8-K and (b) where the failure to receive such authorization, consent, approval, waiver, license, qualification or written exemption from, or to
make such filing, declaration, qualification or registration would not, individually or in the aggregate, be reasonably likely to have a Material Adverse Effect. 

Section 3.09    Investment Company Status. USWS is not and, immediately after
the sale of the Purchased Securities and the application of the net proceeds from such sale will not be, required to register as an “investment company” or a company controlled by an “investment company” within the

investment bankers with respect to the sale of any of the Purchased Securities or the consummation of the transactions contemplated by this Agreement. USWS agrees that it will indemnify and hold harmless each Purchaser from and against any and all
claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by USWS or alleged to have been incurred by USWS in connection with the sale of the Purchased Securities or the consummation
of the transactions contemplated by this Agreement.

(f)    Rule 144. Such Purchaser understands that there is no public trading market for the Purchased Securities, that none
is expected to develop and that the Purchased Securities must be held indefinitely unless and until the Purchased Securities, the Conversion Shares or the Redemption Shares, as applicable, are registered under the Securities Act or an exemption from
registration is available. Such Purchaser has been advised of and is aware of the provisions of Rule 144 promulgated under the Securities Act.

sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Class A Common Stock or any of its Purchased Securities or (b) enter into any swap or other transaction or
arrangement that transfers or that is designed to, or that might reasonably be expected to, result in the transfer to another, in whole or in part, any of the economic consequences of ownership of its Purchased Securities, whether any such
transaction described in clause (a) or (b) above (any such transaction described in clauses (a) and (b), a “Transfer”) is to be settled by delivery of
Class A Common Stock or such other securities, in cash or otherwise. 
 ARTICLE V 

OTHER COVENANTS 
 
Section 5.01    Preemptive Rights. 
 (a)    Except with respect to any Exempt
Issuance, prior to USWS issuing any New Securities following the Closing to a proposed purchaser (the “Proposed Purchaser”), each Purchaser and Lender (together with its Affiliates) that continues to hold outstanding shares of
Series B Preferred Stock at such time (each, an “Eligible Purchaser”) shall have the right to purchase the number of New Securities as provided in this Section 5.01. 

  
 16 












 (b)    USWS shall give each Eligible Purchaser at least ten
(10) Business Days’ prior notice (the “First Notice”) of any proposed issuance of New Securities, which notice shall set forth in reasonable detail the proposed terms and conditions thereof and shall offer to each Eligible
Purchaser (or their designated Affiliates) the opportunity to purchase its Pro Rata Share (which Pro Rata Share shall be calculated as of the date of such notice) of the New Securities at the same price, on the same terms and conditions and at the
same time as the New Securities are proposed to be issued by USWS. If any Eligible Purchaser wishes to exercise such Eligible Purchaser’s preemptive rights, such Eligible Purchaser must do so by delivering an irrevocable written notice to USWS
within five (5) Business Days after delivery of the First Notice by USWS (the “Election Period”), which notice shall state the dollar amount of New Securities such Eligible Purchaser or its Affiliates (each a
“Requesting Purchaser”) would like to purchase up to a maximum amount equal to such Eligible Purchaser’s Pro Rata Share of the total offering amount plus the additional dollar amount of New Securities such Requesting Purchaser
would like to purchase in excess of its Pro Rata Share (the “Over-Allotment Amount”), if any, if other Eligible Purchasers do not elect to purchase their full Pro Rata Share of the New Securities. The rights of each Requesting
Purchaser to purchase a dollar amount of New Securities in excess of each such Requesting Purchaser’s Pro Rata Share of the New Securities shall be based on the relative Pro Rata Shares of the New Securities of those Requesting Purchasers
desiring Over-Allotment Amounts. For the purposes of this Section 5.01, references to “Pro Rata Share” shall refer to the percentage ownership that is obtained by dividing the number of shares of
Class A Common Stock beneficially owned by the applicable Purchaser and its Affiliates on a fully-diluted basis by the total number of Class A Common Stock beneficially owned by all Purchasers and their Affiliates on a fully-diluted basis.

 (c)    If not all of the New Securities are subscribed for by the Eligible Purchasers, taking into account any
Over-Allotment Amounts, USWS shall have the right, but shall not be required, to issue and sell the unsubscribed portion of the New Securities to the Proposed Purchaser at any time during the ninety (90) day period following the termination of
the Election Period pursuant to the terms and conditions set forth in the First Notice. USWS may, in its reasonable discretion, impose such other reasonable and customary terms and procedures such as setting a closing date, rounding the number of
New Securities covered by this Section 5.01 to the nearest whole share and requiring customary closing deliveries in connection with any issuance subject to this Section 5.01. 

Section 5.02    Issuances of New Equity Securities. For a period of six (6) months following the Closing
Date, USWS shall not, and shall cause its Subsidiaries not to, without the prior written consent of Crestview and TCW, issue (a) any securities convertible into or exchangeable or exercisable for Class A Common Stock or
(b) Class A Common Stock, in each case, at a purchase price, conversion price or exercise price, as the case may be, lower than $0.308. Notwithstanding anything to the contrary in this Agreement, this Section 5.02
shall not apply to (i) issuances of equity securities to a director, officer or employee of USWS or any of its Subsidiaries, including, for the avoidance of doubt, any issuances pursuant to the USWS 2018 Stock Incentive Plan, (ii) any
exchange of Class B Common Stock, and a corresponding number of LLC Units, for shares of Class A Common Stock pursuant to the USWS Holdings LLC Agreement and (iii) issuances in connection with any consolidation, merger, division or
other business combination of USWS. 
 Section 5.03    Amendments to Series A
Preferred Stock and Preferred Warrants. 
 (a)    For a period of twenty-four (24) months following the Closing
Date, USWS shall not, without prior written consent of TCW (a) amend, modify or waive any provision of that certain Certificate of Designations of the Series A Preferred Stock, dated May 24, 2019 (the “Series A Certificate of
Designations”), in a manner that would reduce (or have the effect of reducing) the Conversion Price (as defined therein), or (b) amend, modify or waive any provision of that certain Preferred Warrant Agreement dated May 24, 2019 by
and between USWS and Continental Stock Transfer & Trust Company in a manner that would reduce (or have the effect of reducing) the Warrant Price (as defined therein) of the Preferred Warrants issued thereunder. 

  
 17 












 (b)    Without prior written consent of TCW, for as long as it is the
“beneficial owner” under Rule 13d-3 under the Exchange Act of any shares of Series B Preferred Stock, and Matlin, for as long as he is the “beneficial owner” under Rule 13d-3 under the Exchange Act of any shares of Series B Preferred Stock, USWS, shall not initiate or take of any stockholder vote or similar action that would seek to modify the Authorized Share Amount as of the date
hereof, except in connection with a Change of Control (other than a Change of Control arising solely due to the Class A Common Stock ceasing to be listed or quoted on National Securities Exchange). Capitalized terms used in this
Section 5.03(b) but not defined in this Agreement shall have the meaning given to such term in the Series A Certificate of Designations. 

Section 5.04    Director Designation Rights. Subject to the other provisions
of this Section 5.04, for so long as TCW is the “beneficial owner” under Rule 13d-3 under the Exchange Act of any shares of Class A Common Stock, then the Board or a committee thereof will
nominate, and USWS will use its commercially reasonable efforts to cause the stockholders to elect Ryan Carroll to the Board as a Class III Director at the 2021 annual or special meeting of the stockholders of USWS at which Class III
Directors are to be elected to the Board; provided, however, that USWS shall not be bound by the foregoing provision on or after the date that Ryan Carroll ceases to be employed by TCW or its Affiliates. Nothing in this Section 5.04
shall be deemed to prohibit the Board or USWS from taking any action that at least a majority of the members of the Board determines in good faith may be necessary to (i) comply with any rule or regulation of the SEC or NASDAQ or
(ii) comply with applicable law. 
 Section 5.05    TCW Series B Preferred
Voting. 
 (a)    For all shares of Series B Preferred Stock beneficially owned by TCW, or over which TCW has voting
control, TCW hereby irrevocably and unconditionally agrees with Crestview to provide its written consent or affirmative vote (or cause such written consent or affirmative vote to be provided) pursuant to Section 4 (Voting) of the Series A
Certificate of Designations consistent with how Crestview or its Affiliates provides its written consent or affirmative vote on such matters. 

(b)    TCW agrees that it will not transfer any of its shares of Series B Preferred Stock, whether to an Affiliate, a
third party or otherwise, unless and until such transferee has agreed in writing to be bound by the provisions of this Section 5.05, by execution of a Joinder Agreement in a form reasonably agreed to between Crestview and
TCW. 
 ARTICLE VI 

INDEMNIFICATION, COSTS AND EXPENSES 

Section 6.01    Indemnification by USWS. USWS agrees to indemnify each
Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or inquiries),
demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the reasonable fees
and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not
involving a third party claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by USWS contained herein to be true and correct in all material respects as of the date
hereof (except with respect to any provisions including the word “material,” “Material Adverse Effect” or words of similar import, with respect to which such representations and warranties must have been true and
correct) or 

  
 18 












 
(ii) the material breach of any covenants of USWS contained herein, provided that, in the case of the immediately preceding clause (i), such claim for
indemnification is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a Purchaser Related Party shall have given
notice (stating in reasonable detail the basis of the claim for indemnification) to USWS shall constitute the date upon which such claim has been made. 

Section 6.02    Indemnification by the Purchasers. Each Purchaser agrees, severally and not jointly, to
indemnify USWS and its respective Representatives (collectively, “USWS Related Parties”) from, and hold each of them harmless against, any and all losses, actions, suits, proceedings (including any investigations, litigation or
inquiries), demands and causes of action, and, in connection therewith, and promptly upon demand, pay or reimburse each of them for all reasonable costs, losses, liabilities, damages or expenses of any kind or nature whatsoever (including the
reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them),
whether or not involving a third party claim, as a result of, arising out of, or in any way related to (i) the failure of any of the representations or warranties made by such Purchaser contained herein to be true and correct in all material
respects as of the date hereof or (ii) the material breach of any of the covenants of such Purchaser contained herein, provided that, in the case of the immediately preceding clause (i), such claim for indemnification
relating to a breach of any representation or warranty is made prior to the expiration of such representation or warranty; provided, however, that for purposes of determining when an indemnification claim has been made, the date upon which a USWS
Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to such Purchaser shall constitute the date upon which such claim has been made; provided, further, that the liability of such Purchaser
shall not be greater in amount than such Purchaser’s Allocated Purchase Price. 

Section 6.03    Indemnification Procedure. A claim for indemnification for
any matter not involving a third party claim may be asserted by notice to the party from whom indemnification is sought; provided, however, that failure to so notify the indemnifying party shall not preclude the indemnified party from any
indemnification which it may claim in accordance with this Article VI, except as otherwise provided in Sections 6.01 and 6.02. Promptly after any USWS Related Party or Purchaser Related
Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third person, which the Indemnified Party believes in good faith is an
indemnifiable claim under this Agreement, the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such claim or the commencement of such action, suit or proceeding, but failure to so
notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall
state the nature and the basis of such claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at its own expense and by its own counsel, any such matter as long as the Indemnifying Party pursues the same
diligently and in good faith. If the Indemnifying Party undertakes to defend or settle such claim, it shall promptly after such determination, and in no event later than five (5) days, notify the Indemnified Party of its intention to do so, and
the Indemnified Party shall cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and/or the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing
the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s possession or control relevant to the claim. Such cooperation of the Indemnified Party shall be
at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted liability, and for so long as the Indemnifying Party diligently pursues such
defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement 

  
 19 












 
of such asserted liability; provided, however, that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations
of the settlement thereof and (ii) if (A) the Indemnifying Party has, within ten (10) Business Days of when the Indemnified Party provides written notice of a claim, failed (x) to assume the defense or settlement of such claim
and employ counsel or (y) to notify the Indemnified Party of such assumption or (B) if the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have
concluded that there may be reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict
with the interests of the Indemnifying Party, then the Indemnified Party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the expenses and fees of
such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not settle any indemnified claim
without the consent of the Indemnified Party, unless the settlement thereof imposes no liability or obligation on, and includes a complete release from liability of, and does not contain any admission of wrong doing by, the Indemnified Party. 

Section 6.04    Tax Treatment of Indemnification Payments. Any indemnification payments made under this
Article VI shall be treated for all tax purposes as an adjustment to the relevant Purchaser’s Allocated Purchase Price except as otherwise required by applicable Law. 

ARTICLE VII 

TERMINATION 
 
Section 7.01    Termination. This Agreement may be terminated at any time: 

(a)    by mutual written consent of USWS and the Purchasers entitled to purchase a majority of the Purchased Securities as
set forth on Schedule A; 
 (b)    by either USWS or the Purchasers if any court of competent jurisdiction in the
United States or other United States Governmental Authority shall have issued a final order, decree or ruling or taken any other final action restraining, enjoining or otherwise prohibiting the transactions contemplated hereby and such order,
decree, ruling or other action is or shall have become final and nonappealable; 
 (c)    by either USWS or any
Purchaser if the Closing has not been consummated by April 15, 2020 (the “Outside Date”); 

(d)    by USWS if (i) there shall have been a breach of any representation or warranty on the part of the Purchasers
set forth in this Agreement or in any other Basic Document, or if any such representation or warranty of the Purchasers shall have become untrue, in either case such that the conditions set forth in Section 2.04(c) would be
incapable of being satisfied by the Outside Date or (ii) there shall have been a breach in any material respect by the Purchasers of any of their respective covenants or agreements hereunder, and with respect to such
clause (i) or (ii) the Purchasers have not cured such breach or inaccuracy within twenty (20) Business Days after receipt of written notice thereof from USWS; provided that USWS is not then in breach of any
of its obligations hereunder; and 
 (e)    by any Purchaser if (i) there shall have been a breach of any
representation or warranty on the part of USWS set forth in this Agreement or in any other Basic Document, or if any such representation or warranty of USWS shall have become untrue, in either case such that the conditions set forth in
Section 2.04(b) would be incapable of being satisfied by the Outside Date or (ii) there shall have been a breach in any material respect by USWS of its covenants or agreements hereunder, and USWS has


  
 20 












 
not cured such breach or inaccuracy within twenty (20) Business Days after receipt of written notice thereof from the Purchasers; provided that such Purchasers are not then in breach of any
of their obligations hereunder. 
 Section 7.02    Certain Effects of Termination. If this Agreement is
terminated by either USWS or the Purchasers as provided in Section 7.01, except as set forth in Section 8.03, this Agreement shall become null and void and have no further force or effect, but the
parties shall not be released from any liability arising from or in connection with any breach hereof occurring prior to such termination. 

ARTICLE VIII 

MISCELLANEOUS 
 
Section 8.01    Expenses. USWS hereby covenants and agrees to reimburse Crestview Advisors, L.L.C. for its reasonable and documented fees and expenses up to an aggregate amount of $300,000. All other costs and
expenses, including, without limitation, fees and disbursements of counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and
expenses, whether or not the Closing has occurred. 
 Section 8.02    Interpretation. Article, Section,
Schedule and Exhibit references in this Agreement are references to the corresponding Article, Section, Schedule or Exhibit to this Agreement, unless otherwise specified. All Exhibits and Schedules to this Agreement are hereby incorporated and made
a part hereof as if set forth in full herein and are an integral part of this Agreement. All references to instruments, documents, contracts and agreements are references to such instruments, documents, contracts and agreements as the same may be
amended, supplemented and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement
that it follows to the specific or similar items or matters immediately following it. Whenever USWS has an obligation under the Basic Documents, the expense of complying with that obligation shall be an expense of USWS unless otherwise specified.
Any reference in this Agreement to $ shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by any Purchaser, such action shall be in such Purchaser’s sole discretion, unless otherwise specified in this
Agreement. If any provision in the Basic Documents is held to be illegal, invalid, not binding or unenforceable, (i) such provision shall be fully severable and the Basic Documents shall be construed and enforced as if such illegal, invalid,
not binding or unenforceable provision had never comprised a part of the Basic Documents, and the remaining provisions shall remain in full force and effect and (ii) the parties hereto shall negotiate in good faith to modify the Basic Documents
so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. When calculating the
period of time before which, within which or following which any act is to be done or step taken pursuant to the Basic Documents, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. Any words imparting the singular number only shall include the plural and vice versa. The words such as
“herein,” “hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such words appear unless the context otherwise
requires. The provision of a Table of Contents, the division of this Agreement into Articles, Sections and other subdivisions and the insertion of headings are for convenience of reference only and shall not affect or be utilized in construing or
interpreting this Agreement. 
 Section 8.03    Survival of Provisions. The
representations and warranties set forth in Sections 3.02(e), 3.02(f), 3.02(g), 3.07, 3.08, 3.10, 4.02, 4.04 and 4.05 hereunder shall survive the execution and
delivery of this Agreement indefinitely, and the other representations and warranties set forth herein shall survive for a period of six (6) months following the Closing Date regardless of any investigation made


  
 21 












 
by or on behalf of USWS or the Purchasers. The covenants made in this Agreement or any other Basic Document shall survive the Closing and remain operative and in full force and effect regardless
of acceptance of any of the Purchased Securities and payment therefor and repayment, conversion or repurchase thereof. Regardless of any purported general termination of this Agreement, the provisions of Article VI and all
indemnification rights and obligations of USWS and the Purchasers thereunder, Section 7.02 and this Article VIII shall remain operative and in full force and effect as between USWS and the
Purchasers, unless USWS and the Purchasers execute a writing that expressly (with specific references to the applicable Section or subsection of this Agreement) terminates such rights and obligations as between USWS and the Purchasers. 

Section 8.04    No Waiver; Modifications in Writing. 

(a)    Delay. No failure or delay on the part of any party in exercising any right, power or remedy hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are
cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise. 

(b)    Specific Waiver. Except as otherwise provided herein, no amendment, waiver, consent, modification or termination of
any provision of this Agreement or any other Basic Document shall be effective unless signed by each of the parties hereto or thereto affected by such amendment, waiver, consent, modification or termination. Any amendment, supplement or modification
of or to any provision of this Agreement or any other Basic Document, any waiver of any provision of this Agreement or any other Basic Document and any consent to any departure by USWS from the terms of any provision of this Agreement or any other
Basic Document shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on USWS in any case shall entitle USWS to
any other or further notice or demand in similar or other circumstances. Any investigation by or on behalf of any party shall not be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty,
covenant or agreement contained herein. 
 Section 8.05    Binding Effect;
Assignment. 
 (a)    Binding Effect. This Agreement shall be binding upon USWS, each Purchaser and their respective
successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and
permitted assigns. 
 (b)    Assignment of Purchased Securities. All or any portion of Purchased Securities purchased
pursuant to this Agreement may be sold, assigned or pledged by the Purchasers, subject to compliance with applicable securities laws, Sections 4.05(f) and 4.06 hereof and the Registration Rights Agreement, and,
except as provided in the Basic Documents, any such assignment shall not affect the rights of the Purchasers hereunder. 

(c)    Assignment of Rights. Each Purchaser’s rights and obligations hereunder (including the right to seek
indemnification) may be transferred or assigned in whole or in part by such Purchaser to any Affiliate of such Purchaser without the consent of USWS or the other parties hereto. Upon any such permitted transfer or assignment, references in this
Agreement to the Purchasers (as they apply to the transferor or assignor, as the case may be) shall thereafter be deemed to include a reference to such transferee or assignee of such Purchaser unless the context otherwise requires. Without the
written consent of USWS, which consent shall not be unreasonably withheld, no portion of the rights and obligations of 

  
 22 












 
any Purchaser under this Agreement may be assigned or transferred by such Purchaser or such a transferee of Purchased Securities to a Person that is not an Affiliate of such Purchaser. No portion
of the rights and obligations of USWS under this Agreement may be transferred or assigned without the prior written consent of the Purchasers, which consent shall not be unreasonably withheld. 

Section 8.06    Non-Disclosure. USWS, its Subsidiaries and any of
their respective Representatives shall disclose the identity of, or any other information concerning, any Purchaser or any of their Affiliates only after providing such Purchaser a reasonable opportunity to review and comment on such disclosure
(with such comments being incorporated or reflected, to the extent reasonable, in any such disclosure); provided, however, that nothing in this Section 8.06 shall delay any required filing or other disclosure with the SEC,
NASDAQ or any Governmental Authority or otherwise hinder USWS, their Subsidiaries or their Representatives’ ability to timely comply with all laws or rules and regulations of the SEC, NASDAQ or other Governmental Authority. 

Section 8.07    Communications. All notices and demands provided for
hereunder shall be (i) in writing and shall be given by registered or certified mail, return receipt requested, air courier guaranteeing overnight delivery or personal delivery and (ii) via e-mail,

 Section 8.09    Entire
Agreement. This Agreement, the other Basic Documents and the other agreements and documents referred to herein are intended by the parties as a final expression of their agreement and intended to be a complete and exclusive statement of the
agreement and understanding of the parties hereto in respect of the subject matter contained herein and therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or the other Basic
Documents with respect to the rights granted by USWS or any of its Affiliates or the Purchasers or any of their Affiliates set forth herein or therein. This Agreement, the other Basic Documents and the other agreements and documents referred to
herein or therein supersede all prior agreements and understandings between the parties with respect to such subject matter. 

Section 8.10    Governing Law; Submission to Jurisdiction. This Agreement, and all claims or causes of action
(whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any
representation or warranty made in or in connection with this Agreement), will be construed in accordance with and governed by the laws of the State of Delaware without regard to principles of conflicts of laws. Any action against any party relating
to the foregoing shall be brought in any federal or state court of competent jurisdiction located within the State of Delaware, and the parties hereto hereby irrevocably submit to the non-exclusive
jurisdiction of any federal or state court located within the State of Delaware over any such action. The parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any objection which they may now or hereafter have to the
laying of venue of any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit
on the judgment or in any other manner provided by Law. 

Section 8.11    Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT
EACH HEREBY WAIVES, AND AGREES TO CAUSE ITS AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (i) ARISING UNDER THIS AGREEMENT OR (ii) IN ANY WAY
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY OR
OTHERWISE. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART
OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. 

Section 8.12    Execution in Counterparts. This Agreement may be executed in any number of counterparts and by
different parties hereto in separate counterparts, each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same Agreement. A signed
copy of this Agreement delivered by portable document format (PDF) 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; provided, however, that each party
hereto shall deliver an original signed copy of this Agreement executed by such party to any other party hereto promptly upon the request of any such other party. 

  
 24 













Section 8.13    Recapitalizations, Exchanges, Etc. Affecting the Purchased
Securities. The provisions of this Agreement shall apply to the full extent set forth herein with respect to any and all equity interests of USWS or any successor or assign of USWS (whether by merger, consolidation, sale of assets or otherwise)
which may be issued in respect of, in exchange for or in substitution of, the Purchased Securities. 

Section 8.14    Certain Tax Matters. 

(a)    USWS shall pay any and all documentary, stamp or similar issue or transfer tax due on (i) the issue of the
Purchased Securities and (ii) the issue of shares of Class A Common Stock upon conversion or redemption of the Purchased Securities. 

(b)    The Purchasers and USWS agree not to treat the Series B Preferred Stock (based on the terms as set forth in the
Certificate of Designations) as “preferred stock” within the meaning of Section 305 of the Code and U.S. Treasury Regulation § 1.305-5 for U.S. federal income tax and withholding tax purposes and shall not take any
position inconsistent with such treatment, including on any applicable U.S. federal income or state tax return or in connection with any audit or other proceeding, except as required by a final “determination” within the meaning of
Section 1313(a) of the Code. USWS agrees that, provided that each Purchaser delivers to USWS a properly executed IRS Form W-9, or similar form sufficient to cause under current Law USWS (including any
paying agent of USWS) to avoid a requirement to withhold on any payments or deemed payments to any such Purchaser, USWS (including any paying agent of USWS) will not withhold on any payments or deemed payments to any such Purchaser.
