Such Purchaser has been advised of and is aware of the provisions of Rule 144 promulgated under the Securities Act.

(g)    Reliance by USWS. Such Purchaser understands that the Purchased Securities are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities laws and that USWS is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Purchased Securities, the Conversion Shares and the Redemption Shares.

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.

(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

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.

Section 8.04    No Waiver; Modifications in Writing.

(a)    Delay.

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.

NOW, THEREFORE, in consideration of the premises and the agreements, provisions and covenants herein contained, the parties hereto agree as follows:

Each Lender is an “accredited investor,” as such term is defined in Rule 501 of Regulation D promulgated under the Securities Act. Each Lender acknowledges and understands that (A) the acquisition of neither the Class A Common Stock nor the Series B Preferred Stock has not been registered under the Securities Act in reliance on an exemption therefrom, and (B) that the shares of the Class A Common Stock and the Series B Preferred Stock will, upon their acquisition by the Lenders at Closing, be characterized as “restricted securities” under state and federal securities laws and may not be sold, transferred, offered for sale, pledged, hypothecated, or otherwise disposed of, except pursuant to an effective registration statement under the Securities Act or pursuant to an exemption from the registration requirements of the Securities Act, and in compliance with applicable state and federal securities laws.

Each Lender further acknowledges and agrees that it was solicited or became aware of the investment in the Class A Common Stock and the Series B Preferred Stock through direct contact with Parent or its agents outside of any public offering effort.

(c)    the respective conditions set forth in Section 2.04(a) and Section 2.04(b) of the Purchase Agreement to the obligations of each party thereto to consummate the purchase and issuance and sale of the Series B Preferred Stock thereunder shall have been satisfied or waived (by each Lender) on or prior to the Second Amendment Effective Date;

(d)    immediately prior to and after giving effect to this Second Amendment, all representations and warranties of each Loan Party contained in Article IV of the Credit Agreement are true and correct in all material respects on and as of the date of this Second Amendment and the Second Amendment Effective Date as if made on and as of such date (or if stated to have been made at an earlier date, were true and correct in all material respects as of such earlier date) (except to the extent any such representation and warranty itself is qualified by “materiality”, “Material Adverse Effect” or similar qualifier, in which case, it shall be true and correct in all respects);

(e)    as of the date hereof, no Default or Event of Default has occurred and is continuing;

(f)    the Administrative Agent and the Lenders shall have been paid or reimbursed by the Borrower for all costs and expenses associated with the preparation, negotiation and execution of this Second Amendment and the other instruments and documents to be delivered hereunder and in connection with the transactions contemplated hereby (including, the reasonable, documented and out-of-pocket accrued and unpaid fees and expenses of counsel thereto to the extent invoiced at least one Business Day prior to the Second Amendment Effective Date);

(g)    the Borrower shall have made in full (and the Administrative Agent shall have received) all payments (including all Scheduled Amortization Payments (as defined in the Original Credit Agreement), interest, fees, costs and expenses) due under the Loan Documents prior to the Second Amendment Effective Date (without giving effect to any amendments to the Original Credit Agreement made as of such Second Amendment Effective Date); and

(h)    the Administrative Agent shall have received an opinion of counsel for the Loan Parties, in form and substance reasonably satisfactory to the Administrative Agent (including, without limitation, with respect to the enforceability of this Second Amendment ).

(a)    Reference to Credit Agreement. Upon and after the Second Amendment Effective Date, each reference in the other Loan Documents to the “Credit Agreement”, “thereunder”, “thereof” or words of like import referring to the Credit Agreement shall mean and be a reference to the Credit Agreement as modified by this Second Amendment.

(b)    Effect on Loan Documents. This Second Amendment shall constitute an amendment of the Credit Agreement made under and in accordance with the terms of Section 9.01 of the Credit Agreement. Except as specifically amended by this Second Amendment, the Loan Documents shall remain in full force and effect and the execution, delivery and performance of this Second Amendment shall not constitute a waiver of any other provision of, or operate as a waiver of any other right, power or remedy of any Agent or Lender under any of the Loan Documents. Except as expressly provided herein, each Loan Document is and shall remain unchanged and in full force and effect and nothing contained in this Second Amendment shall abrogate, prejudice, diminish or otherwise affect any powers, right, remedies or obligations of any Person arising before the date of this Second Amendment. This Second Amendment shall not constitute a novation of the obligations and liabilities of the parties under the Credit Agreement or the other Loan Documents as in effect on or prior to the Second Amendment Effective Date. Except as provided for herein and in the Credit Agreement nothing herein shall be deemed to entitle the Borrower to a further consent to, or a further waiver, amendment, modification or other change of, any of the terms, conditions, obligations, covenants or agreements contained in the Credit Agreement or any other Loan Document in similar or different circumstances.
