This Amendment No. 3 to Schedule 13D (this “Statement”) amends and restates the Schedule 13D originally filed by the Reporting Persons (as defined below) on November 19, 2018, as amended by Amendment No. 1 to the Schedule 13D filed by the Reporting Persons on May 29, 2019, as further amended by Amendment No. 2 to the Schedule 13D filed by the Reporting Persons on November 12, 2019.

This Statement relates to the Class A common stock, par value $0.0001 per share (the “Class A Common Stock”) of U.S. Well Services, Inc., a Delaware corporation (the “Issuer”). The Class A Common Stock and Class B common stock, par value $0.0001 per share, of the Issuer (the “Class B Common Stock” and, together with the Class A Common Stock, the “Common Stock”) are treated as a single class for purposes of this Statement because they vote together as a single class.

The principal executive offices of the Issuer are located at 770 South Post Oak Lane, Suite 405, Houston, TX 77056.

The names of the persons filing this Statement are Crestview Partners III GP, L.P. (“Crestview GP”), Crestview III USWS, L.P. (“Crestview III LP”) and Crestview III USWS TE, LLC (“Crestview III LLC,” and together with Crestview III LP, the “Crestview Parties” and, together with Crestview GP, the “Reporting Persons” and each, a “Reporting Person”). Crestview GP and Crestview III LP are each a Delaware limited partnership. Crestview III LLC is a Delaware limited liability company. Each of the Reporting Persons is a private investment fund. Crestview GP serves as the general partner of the investment funds which are direct or indirect members of the Crestview Parties. Decisions by Crestview GP to vote or dispose of the Class A Common Stock held by the Crestview Parties requires the approval of a majority of the seven members of its investment committee and its chairman, which is composed of the following individuals: Barry S. Volpert (chairman), Thomas S. Murphy, Jr., Richard M. DeMartini, Robert V. Delaney, Jr., Brian P. Cassidy, Alexander M. Rose and Adam J. Klein. None of the foregoing persons has the power individually to vote or dispose of any of the Class A Common Stock held by the Crestview Parties. Each of the foregoing individuals, in his capacity as solely a member of the investment committee, disclaims beneficial ownership of all such Class A Common Stock. The address of the principal office of each of the Reporting Persons is c/o Crestview, 590 Madison Avenue, 42nd Floor, New York, New York 10022.

During the last five years, none of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

The Crestview Parties collectively purchased 20,250,000 shares of Class A Common Stock (the “Acquired Shares”) and 7,250,000 private placement warrants with each warrant exercisable for one-half of one share of Class A Common Stock at an exercise price of $5.75 per half share, or $11.50 per whole share (the “Initial Warrants”) for aggregate consideration of $180,000,000 pursuant to the Subscription Agreement (the “Subscription Agreement”), dated July 13, 2018, by and among Matlin & Partners Acquisition Corporation, Matlin & Partners Acquisition Sponsor LLC, Cantor Fitzgerald & Co., the Crestview Parties, and, solely for purposes of Section 12(a) therein, Crestview Partners III (TE), L.P. (“VCOC I”) and Crestview Partners III Co-Investors, L.P. (“VCOC II,” and, together with VCOC I, “Crestview VCOC”). The Initial Warrants became exercisable 30 days after the closing of the Merger Agreement (as discussed in Item 4), which closed on November 9, 2018. The source of funds for such purchase was capital contributions made by the investors in each of the Crestview Parties as well as available lines of credit.

On May 24, 2019 (the “Series A Preferred Closing”), the Crestview Parties collectively purchased 20,000 shares of Series A Redeemable Convertible Preferred Stock of the Issuer, par value $0.0001 per share (the “Series A Preferred Stock”), and 1,066,666 warrants exercisable as described in Item 4 below (the “May 2019 Warrants”) for aggregate consideration of $20,000,000 pursuant to the Series A Purchase Agreement dated May 23, 2019 by and among the Crestview Parties, the Issuer and the other purchasers party thereto (the “Series A Purchase Agreement”). In addition,

the Series A Purchase Agreement provides that the Issuer will issue the Crestview Parties 177,778 additional warrants exercisable as described in Item 4 below (the “Additional May 2019 Warrants” and, together with the May 2019 Warrants, the “Preferred Warrants”) beginning on March 31, 2020 and on a quarterly basis thereafter for a total of up to nine such issuances, in each case, if the shares of Series A Preferred Stock remain outstanding as of such applicable date. The source of funds for such purchase was capital contributions made by the investors in each of the Crestview Parties as well as available lines of credit. On March 31, 2020, in accordance with the terms of the Series A Purchase Agreement, the Issuer issued 177,778 Additional May 2019 Warrants to the Crestview Parties.

On April 1, 2020 (the “Series B Preferred Closing”), the Crestview Parties collectively purchased 11,500 shares of Series B Redeemable Convertible Preferred Stock of the Issuer, par value $0.0001 per share (the “Series B Preferred Stock”), for aggregate consideration of $11,500,000 pursuant to the Series B Purchase Agreement dated March 31, 2020 (the “Series B Purchase Agreement” and, together with the Series A Purchase Agreement, the “Purchase Agreements”) by and among the Crestview Parties, the Issuer and the other purchasers party thereto (the “Series B Purchasers”). The source of funds for such purchase was capital contributions made by the investors in each of the Crestview Parties.

The following describes any other plans or proposals that any Reporting Person may have with respect to the matters set forth in Item 4(a)-(j) of Schedule 13D:

On July 13, 2018, the Issuer entered into a Merger and Contribution Agreement (the “Merger Agreement”), by and among the Issuer, MPAC Merger Sub LLC, USWS Holdings, certain owners of equity interests in USWS Holdings and, solely for the purposes specified therein, the seller representative named therein. In connection with the entry into the Merger Agreement, the Issuer entered into a Subscription Agreement, pursuant to which (i) the Reporting Persons purchased the Acquired Shares and the Initial Warrants and (ii) the Issuer agreed that Crestview VCOC shall have the right to designate (x) two directors to the board of directors of the Issuer so long as the Crestview Parties beneficially own at least 14.3% of the outstanding Class A Common Stock and (y) one director to the board of directors of the Issuer so long as the Crestview Parties beneficially own at least 5% and less than 14.3% of the Class A Common Stock. Adam J. Klein, who is a Partner of each of Crestview, L.L.C. and Crestview Advisors, L.L.C., currently serves as Crestview VCOC’s designee on the Issuer’s board of directors, and in such capacity may have influence over the corporate activities of the Issuer.

Concurrently with the closing of transactions contemplated by the Merger Agreement, each of the Crestview Parties entered into the Amended and Restated Registration Rights Agreement, dated November 9, 2018 (the “Registration Rights Agreement”) with the Issuer and certain other stockholders of the Issuer listed on the signature pages thereto. The Registration Rights Agreement includes customary provisions relating to, among other things, “demand” registration rights and “piggy-back” registration rights. Pursuant to the Registration Rights Agreement, the Issuer will have certain obligations to register for resale under the Securities Act of 1933, as amended (the “Securities Act”), (i) all or any portion of the shares of Class A Common Stock that the holders hold as of the date of such agreement and that they may acquire thereafter, including upon the conversion, exercise or exchange of any other security therefor and (ii) the Initial Warrants.

Subject to the terms and conditions of the Certificate of Designations the Issuer filed with the Delaware Secretary of State on May 24, 2019 (the “Series A Certificate of Designations”), following the first anniversary of the Series A Preferred Closing, all or any portion of the shares of Series A Preferred Stock may be converted into Class A Common Stock at any time based on the then-applicable liquidation preference (as determined in accordance with the Series A Certificate of Designations) divided by the applicable conversion price. The ordinary conversion price of the Series A Preferred Stock is $6.67 and is subject to adjustment for stock splits, combinations, certain distributions or similar events. However, if the Issuer exercises its right to redeem the Series A Preferred Stock and funds such redemption with proceeds from an equity offering within one year of the Series A Preferred Closing, the conversion price will be the higher of the price to the public in such offering and the ordinary conversion price. As a result, the number of shares of Class A Common Stock issuable upon conversion of the shares of Series A Preferred Stock cannot be determined at this time, though the Series A Certificate of Designations provides that the shares of Series A Preferred

Stock held by the Crestview Parties may not be converted into more than 4,960,000 shares of Class A Common Stock, subject to certain adjustments as provided therein.

Subject to the terms and conditions of the Series A Certificate of Designations, the Series A Preferred Stock is also subject to redemption by the Issuer at any time and may be automatically converted at the election of the Issuer if (i) the closing price of the Class A Common Stock is greater than 130% of the conversion price for 20 trading days over any 30 consecutive trading day period and (ii) the average daily trading volume of the Class A Common Stock exceeded 250,000 for 20 trading days over any 30 consecutive trading day period.

The Preferred Warrants are subject to the terms and conditions of a Warrant Agreement dated May 24, 2019 by and between the Issuer and Continental Stock Transfer & Trust Company as warrant agent (the “Preferred Warrant Agreement”). Subject to the terms and conditions of the Preferred Warrant Agreement, the Crestview Parties may acquire shares of Class A Common Stock based on an exercise price of $7.66 per share (subject to adjustments for stock splits, combinations, certain distributions or similar events) from time to time beginning with the date that is six months following the Series A Preferred Closing and for six years thereafter. The Preferred Warrants are required to be net settled in stock on a cashless basis based on the difference between (i) the volume weighted average price of the Class A Common Stock as reported during the ten trading day period ending on the second trading day prior to the date on which the notice of exercise is delivered to the warrant agent and (ii) the then-applicable exercise price, in each case, at the time of exercise. As a result, the number of shares of Class A Common Stock issuable upon exercise of the Preferred Warrants cannot be determined at this time, though in no event will the Preferred Warrants be exercisable for more than 1,244,444 shares of Class A Common Stock (subject to adjustment for stock splits, combinations, certain distributions or similar events).

The Series A Purchase Agreement provides that the Issuer will issue the Crestview Parties 177,778 Additional May 2019 Warrants beginning on March 31, 2020 and on a quarterly basis thereafter for a total of up to nine such issuances, in each case, if the shares of Series A Preferred Stock remain outstanding as of such applicable date. In accordance with the terms of the Series A Purchase Agreement, the Issuer issued 177,778 Additional May 2019 Warrants to the Crestview Parties on March 31, 2020. The Additional May 2019 Warrants are subject to the terms and conditions of the Preferred Warrant Agreement.

Subject to the terms and conditions of the Series B Certificate of Designations the Issuer filed with the Delaware Secretary of State on March 31, 2020 (the “Series B Certificate of Designations” and, together with the Series A Certificate of Designations, the “Certificates of Designations”), all or any portion of the shares of Series B Preferred Stock may be converted into Class A Common Stock at any time based on the then-applicable liquidation preference (as determined in accordance with the Series B Certificate of Designations) divided by the applicable conversion price. The ordinary conversion price of the Series B Preferred Stock is $0.308 per share and is subject to adjustment for stock splits, combinations, certain distributions or similar events.

Subject to the terms and conditions of the Series B Certificate of Designations, (a) the Series B Preferred Stock is subject to redemption by the Issuer at any time after the date that is eighteen (18) months after the issuance date of the Series B Preferred Stock, and (b) following the third anniversary of the issuance date of the Series B Preferred Stock, any time the Class A Common Stock is listed on a national securities exchange, the Series B Preferred Stock is subject to conversion by the Issuer and may be automatically converted at the election of the Issuer if (i) the closing price of the Class A Common Stock is greater than 130% of the conversion price for 20 trading days over any 30 consecutive trading day period and (ii) the average daily trading volume of the Class A Common Stock exceeded 250,000 for 20 trading days over any 30 consecutive trading day period.

Concurrently with the closing of transactions contemplated by the Series A Purchase Agreement, each of the Crestview Parties entered into the Registration Rights Agreement, dated May 24, 2019 (the “Series A Registration Rights Agreement”) with the Issuer and certain other stockholders of the Issuer listed on the signature pages thereto. Concurrently with the closing of the transactions contemplated by the Series B Purchase Agreement, the Crestview Parties entered into the Series B Registration Rights Agreement, dated April 1, 2020, with the Issuer and certain other stockholders of the Issuer listed on the signature pages thereto (the “Series B Registration Rights Agreement” and, together with the Series A Registration Rights Agreement, the “Preferred Registration Rights Agreements”). The Preferred Registration Rights Agreements include customary provisions relating to, among other things, “demand” registration rights and “piggy-back” registration rights. Pursuant to the Preferred Registration Rights Agreements, the Issuer will have certain obligations to register for resale under the Securities Act of 1933, as amended (the “Securities

Act”), all or any portion of the shares of Class A Common Stock that the holders may acquire upon the conversion, exercise or exchange of shares of Series A Preferred Stock, the Series B Preferred Stock or the Preferred Warrants.

The foregoing descriptions of the Merger Agreement, the Registration Rights Agreement, the Purchase Agreements, the Certificates of Designations, the Preferred Warrant Agreement and the Preferred Registration Rights Agreements do not purport to be complete and are subject to, and qualified in their entirety by, the full text of the Merger Agreement, the Registration Rights Agreement, the Series A Purchase Agreement, the Series A Certificate of Designations, the Preferred Warrant Agreement, the Series A Registration Rights Agreement, the Series B Purchase Agreement, the Series B Certificates of Designations or the Series B Registration Rights Agreement, copies of which are being incorporated by reference as Exhibits 2, 4, 6, 7, 8, 9, 11, 12 and 13, respectively, in Item 7 of this Statement and are incorporated herein by reference.

The Reporting Persons acquired the securities covered by this Statement for investment purposes and the Reporting Persons intend to review on a continuing basis the investments in the Issuer by the Reporting Persons. Depending upon market conditions and other factors that they may deem relevant, the Reporting Persons or their affiliates may seek to acquire additional securities of the Issuer or other financial instruments related to the Issuer or its securities (which may include rights or securities exercisable or convertible into securities of the Issuer) and/or sell or otherwise dispose of some or all of the Issuer securities or financial instruments owned from time to time, in each case, in open market or private transactions, block sales or otherwise, including in connection with extraordinary corporate transactions such as a tender offer, merger or consolidation.

The Reporting Persons intend to communicate with the Issuer’s management and board of directors about a broad range of operational and strategic matters and may communicate with other stockholders or third parties regarding the foregoing. The Reporting Persons may formulate, consider, explore, develop or make plans or proposals regarding the Issuer or its securities, including related to operational or financial matters or any other potential strategic alternative intended to maximize shareholder value, including but not limited to a business combination, acquisition, sale of the Issuer or a take private transaction. Such discussions and actions may be preliminary and exploratory in nature and not rise to the level of a plan or a proposal.

(a) and (b)

The below table sets forth the number of shares of Class A Common Stock directly and beneficially owned by each of the Reporting Persons. The shares directly owned by the Crestview Parties are deemed to be beneficially owned by Crestview GP, the general partner of the investment funds which are direct or indirect members of the Crestview Parties. Accordingly, as indicated with respect to such shares listed as beneficially owned in the below table, the applicable Reporting Persons have shared voting power to vote and direct the vote of, and have shared power to dispose and direct the disposition of, such shares. Neither Crestview III LP nor Crestview III LLC have the sole power to vote or direct the vote, or the sole power to dispose or direct the disposition of, the shares listed in the table below. Each Reporting Person expressly disclaims, to the extent permitted by applicable law, beneficial ownership of any Common Stock held by the other Reporting Persons. 

________________

(as discussed in Item 3), (iv) 1,244,444 shares of Class A Common Stock issuable upon exercise of the Preferred Warrants, consisting of (A) 1,066,666 May 2019 Warrants and (B) 177,778 Additional May 2019 Warrants (as discussed in Item 3) issued to Crestview III USWS, L.P. and Crestview III USWS TE, LLC pursuant to the Series A Purchase Agreement, (v) 3,276,543 shares of Class A Common Stock issuable on or after May 24, 2020, upon conversion of the 20,000 shares of Series A Preferred Stock issued to Crestview III USWS, L.P. and Crestview III USWS TE, LLC pursuant to the Series A Purchase Agreement (as discussed in Item 3) and (vi) 37,337,662 shares of Class A Common Stock issuable on or after April 1, 2020, upon conversion of the 11,500 shares of Series B Preferred Stock issued to Crestview III USWS, L.P. and Crestview III USWS TE, LLC pursuant to the Series B Purchase Agreement (as discussed in Item 3), in each case, for which Crestview Partners III GP, L.P. may be deemed to be the beneficial owner. Excludes any shares of Class A Common Stock that may be issued upon exercise of any Additional May 2019 Warrants that may be issued after the date hereof pursuant to the terms of the Series A Purchase Agreement (as discussed in Item 3).

On November 9, 2018, Crestview III LLC and Crestview III LP entered into a Side Letter (the “Side Letter”) by and between Crestview III LLC, Crestview III LP, Matlin & Partners Acquisition Corporation and Matlin & Partners Acquisition Sponsor LLC (the “Sponsor”), pursuant to which the Sponsor agreed to transfer an aggregate of 125,000 shares of Class A Common Stock to Crestview III LP and Crestview III LLC (the “Sponsor Transferred Shares”). The Sponsor Transferred Shares were to be held by the Sponsor until the satisfaction of certain vesting conditions described in the Side Letter, however, on July 3, 2019 the Sponsor transferred the Sponsor Transferred Shares to Crestview III LP and Crestview III LLC in connection with the winding up of Sponsor’s operations and pursuant to the First Amendment to the Side Letter, a copy of which is attached hereto as Exhibit 10. The Sponsor Transferred Shares remain subject to the vesting conditions described in the original Side Letter, a copy of which is being incorporated by reference as Exhibit 5.

Pursuant to the terms of the Series B Purchase Agreement, the Issuer agreed that, for so long as the Crestview Parties continue to beneficially own the Series B Preferred Stock, in the event the Issuer makes any issuance that is not a public offering of any shares of (i) preferred stock, (ii) Class A Common Stock or (iii) other security that is convertible into, exercisable or exchangeable for, or which otherwise entitles the holder thereof to acquire Class A Common Stock, then, subject to certain exceptions, the Crestview Parties will be afforded the opportunity to acquire from the Issuer for the same price and on the same terms as such securities are proposed to be offered to other purchasers, up to their Pro Rata Share of such new securities. The term “Pro Rata Share” as used in the Series B Purchase Agreement refers to the percentage ownership that is obtained by dividing the number of shares of Class A Common Stock beneficially owned by the Crestview Parties and their affiliates on a fully-diluted basis by the total number of the Class A Stock beneficially owned by the Series B Purchasers and their affiliates on a fully-diluted basis.

Additionally, the Series B Purchase Agreement provides that, subject to certain exceptions, for a period of six (6) months following the issuance of the Series B Preferred Stock, the Issuer must obtain the written consent of Crestview prior to issuing, or causing its subsidiaries to issue, any shares of Class A Common Stock or any securities convertible, exchangeable or exercisable for shares of Class A Common Stock, in each case, at a price lower than $0.308 per share.

The Series B Purchase Agreement also provides that Regiment Capital Special Situations Fund V, L.P. (“TCW”) shall vote its shares of Series B Preferred Stock pursuant to Section 4 (Voting) of the Series A Certificate of Designations consistent with how Crestview or its affiliates votes on such matters. TCW has also agreed to not transfer any of its shares of Series B Preferred Stock unless such transferee agrees to be bound by such obligation.

Except as otherwise described in this Statement and the agreements incorporated by reference herein and set forth as exhibits hereto, to the Reporting Persons’ knowledge, there are no other contracts, arrangements, understandings or relationships (legal or otherwise) among the entities named in Item 2 and between such entities and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or losses or the giving or withholding of proxies.

Except for the fees payable to Piper Sandler & Co., through its Simmons Energy division, in its capacity as the financial advisor to the special committee of the Board, no fees or commissions are or will be payable by USWS to brokers, finders or investment bankers with respect to the sale of any of the Purchased Securities or the consummation of the transactions contemplated by this Agreement.

This Agreement and the Basic Documents to which such Purchaser is or will be a party have been duly executed and delivered by such Purchaser and constitute or, when executed by such Purchaser, will constitute legal, valid and binding obligations of such Purchaser; provided that, the enforceability thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity and except as the rights to indemnification may be limited by applicable law (regardless of whether such enforceability is considered in a proceeding in equity or at law).

Section 4.03 No Breach. The execution, delivery and performance of this Agreement and the Basic Documents by such Purchaser and the consummation by such Purchaser of the transactions contemplated hereby or thereby will not (a) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any material agreement to which such Purchaser is a party or by which such Purchaser is bound or to which any of the property or assets of such Purchaser is subject, (b) if such Person is a non-natural Person, conflict with or result in any violation of the provisions of the organizational documents of such Purchaser or (c) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over such Purchaser or the property or assets of such Purchaser, except in the case of clauses (a) and (c), for such conflicts, breaches, violations or defaults as would not have a material adverse effect on the ability to consummate the transactions contemplated by this Agreement and the Basic Documents.

Section 4.05 Unregistered Securities.

(a)  Accredited Investor Status; Sophisticated Purchasers. Such Purchaser is an “accredited investor” within the meaning of Rule 501 under the Securities Act and is able to bear the risk of its investment in Purchased Securities, the Conversion Shares and the Redemption Shares. Such Purchaser has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the purchase of the Purchased Securities, the Conversion Shares and the Redemption Shares.

(b)  Information. Such Purchaser and its Representatives have been furnished with all materials relating to the business, finances and operations of USWS that have been requested and materials relating to the offer and sale of the Purchased Securities that have been requested by such Purchaser and its Representatives. Such Purchaser and its Representatives have been afforded the opportunity to ask questions of USWS. Neither such inquiries nor any other due diligence investigations conducted at any time by any Purchaser and Representatives shall modify, amend or affect such Purchaser’s right (i) to rely on USWS’s representations and warranties contained in Article III above or (ii) to indemnification or any other remedy based on, or with respect to the accuracy or inaccuracy of, or compliance with, the representations, warranties, covenants and agreements in this Agreement, or any Basic Document. Such Purchaser understands that the purchase of the Purchased Securities involves a high degree of risk. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Purchased Securities.

(c)  Cooperation. Such Purchaser shall cooperate reasonably with USWS to provide any information necessary for any applicable securities filings required to be made by USWS.

(d)  Legends. Such Purchaser understands that the Purchased Securities will bear a restrictive legend substantially in the form as set forth in the Certificate of Designations.

(e)  Purchase Representation. Such Purchaser is purchasing the Purchased Securities for its own account and not with a view to distribution in violation of any securities laws. Such Purchaser

has been advised and understands that none of the Purchased Securities, the Conversion Shares or the Redemption Shares have been registered under the Securities Act or under the “blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the Securities Act or pursuant to another available exemption from the registration requirements of the Securities Act). Such Purchaser has been advised and understands that USWS, in issuing the Purchased Securities, is relying upon, among other things, the representations and warranties of such Purchaser contained in this Article IV in concluding that such issuance is a “private offering” and is exempt from the registration provisions of the Securities Act.

(f)  Rule 144. Such Purchaser understands that there is no public trading market for the Purchased 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.

(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.

Section 4.06 Short Selling. Such Purchaser has not engaged in any Short Sales involving Class A Common Stock owned by it between the time it first began discussions with USWS about the transaction contemplated by this Agreement and the date of execution of this Agreement.

Section 4.07 Lock-Up Agreement. Without the prior written consent of USWS, except in the case of a Permitted Transfer or as otherwise specifically provided in this Agreement, each Purchaser will not, during the period commencing on the date hereof and ending sixty (60) days after the date of the Closing (such period, the “Purchaser Lock-Up Period”) (a) offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any 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.

(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.

(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

(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.

Article VII

Section 8.03 Survival of Provisions.

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.

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.

SERIES B REDEEMABLE CONVERTIBLE PREFERRED STOCK

(Par Value $0.0001 Per Share)

U.S. Well Services, Inc. (the “Corporation”), a corporation organized and existing under and by virtue of the provisions of the General Corporation Law of the State of Delaware (the “General Corporation Law”), hereby certifies that, pursuant to the authority expressly granted to and vested in the Board of Directors of the Corporation (the “Board of Directors”) by the Second Amended and Restated Certificate of Incorporation of the Corporation (as amended from time to time in accordance with its terms and the General Corporation Law, the “Certificate of Incorporation”), which authorizes the Board of Directors, by resolution, to provide out of the unissued shares of the preferred stock (the “Preferred Stock”) for one or more series of Preferred Stock and to establish from time to time the number of shares to be included in each such series and to fix the voting rights (if any), designations, powers, preferences and relative, participating, optional, special and other rights (if any) of each such series and any qualifications, limitations and restrictions thereof, and in accordance with the provisions of Section 151 of the General Corporation Law, the Board of Directors duly adopted on March 30, 2020 the following resolution:

RESOLVED, that the rights, powers and preferences, and the qualifications, limitations and restrictions, of the Series B Preferred Stock as set forth in the Certificate of Designations are hereby approved and adopted by the Board and Series B Preferred Stock is hereby authorized out of the Corporation’s authorized preferred stock, par value $0.0001 per share; and the form, terms and provisions of the Certificate of Designations are hereby approved, adopted, ratified and confirmed in all respects as follows:

(a)   The shares of such series shall be designated the Series B Redeemable Convertible Preferred Stock (hereinafter referred to as the “Series B Preferred Stock”). Concurrently with the adoption of this Certificate of Designations, the Board of Directors is authorizing warrants to acquire shares of Class A Common Stock (as defined below).

(b)   Each share of Series B Preferred Stock shall be identical in all respects with the other shares of Series B Preferred Stock.

(c)   The authorized number of shares of Series B Preferred Stock shall initially be 22,050, which number may from time to time be increased or decreased by resolution of the Board of Directors as permitted by the General Corporation Law.

(d)  For purposes of this Certificate of Designations, “Capital Stock” of any person means any and all shares, interests, participations or other equivalents however designated of corporate stock or other equity participations, including partnership interests, whether general or limited, of such person and any rights (other than debt securities convertible or exchangeable into an equity interest), warrants or options to acquire an equity interest in such person. The Series B Preferred Stock shall, with respect to dividend rights and rights upon a liquidation, winding-up or dissolution of the Corporation, rank:

(i)   senior to the Class A Common Stock, par value $0.0001 per share, of the Corporation (“Class A Common Stock”), the Class B Common Stock, par value $0.0001 per share, of the Corporation (“Class B Common Stock”), and any other class or series of Capital Stock of the Corporation, the terms of which do not expressly provide that such class or series ranks senior to or on a parity with the Series B Preferred Stock with respect to dividend rights or rights upon a liquidation, winding-up or dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Junior Stock”);

(ii)   on a parity with (A) the Corporation’s Series A Redeemable Convertible Preferred Stock, par value $0.0001 (the “Series A Preferred Stock”), and (B) any class or series of Capital Stock of the Corporation, the terms of which provide that such class or series ranks on a parity with the Series B Preferred Stock with respect to dividend rights or rights upon a liquidation, winding-up or dissolution of the Corporation (collectively the Series A Preferred Stock and such Capital Stock, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Parity Stock”); and

(iii)   junior to any class or series of Capital Stock of the Corporation (other than Class A Common Stock and Class B Common Stock), the terms of which expressly provide that such class or series ranks senior to the Series B Preferred Stock with respect to dividend rights or rights upon a liquidation, winding-up or dissolution of the Corporation (collectively, together with any warrants, rights, calls or options exercisable for or convertible into such Capital Stock, the “Senior Stock”).

(e)   For purposes of this Certificate of Designations, the following terms have meanings set forth in the Section indicated:

(a)   Holders of Series B Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors, and the Corporation shall pay, out of funds lawfully available therefor, cumulative dividends at the rate per share of Series B Preferred Stock equal to the Series B Dividend Rate (the “Series B Dividend”). The “Series B Dividend Rate” shall mean (i) for the

period commencing on the closing date of the issuance of the shares of Series B Preferred Stock (the “Issuance Date”) and ending on May 24, 2021, 12.00% per annum on the then-applicable Liquidation Preference (as defined herein) per share of Series B Preferred Stock, and (ii) from and after May 24, 2021, 16.00% per annum on the then-applicable Liquidation Preference per share of Series B Preferred Stock. The period from the Issuance Date to and including May 24, 2020 and each period from but excluding a Dividend Payment Date to and including the following Dividend Payment Date is herein referred to as a “Dividend Period.” “Dividend Payment Date” shall mean February 24, May 24, August 24 and November 24 of each year, commencing on May 24, 2020.

(b)  Series B Dividends shall be payable quarterly or in arrears at the Series B Dividend Rate and shall compound quarterly and accumulate, whether or not earned or declared, from the most recent date on which dividends have been paid, or, if no dividends have been paid, from the Issuance Date.

(c)   If a Series B Dividend is declared by the Board of Directors, then such Series B Dividend shall be paid in cash. The Board of Directors shall not be required to declare any Series B Dividends, and any declaration of a Series B Dividend shall be solely at the discretion of the Board of Directors of the Corporation.

(d)   If a cash dividend is not declared and paid in cash on a Dividend Payment Date, then in full discharge of any accrual of cash dividends for such Dividend Period, the Liquidation Preference of each outstanding share of Series B Preferred Stock, regardless of its date of issue, shall automatically increase on such Dividend Payment Date by an amount equal to the Series B Dividend Rate multiplied by the Liquidation Preference in effect immediately after the immediately prior Dividend Payment Date (or the Issuance Date in respect of the first Dividend Period) (such automatic increase, the “PIK Accrual”).

(e)   All cash dividends paid or declared for payment on a dividend payment date with respect to the Series B Preferred Stock and the Parity Stock shall be shared pro rata based on the then-current dividends due on shares of Series B Preferred Stock and (i) in the case of any series of non-cumulative Parity Stock, the aggregate of the current and unpaid dividends due on such series of Parity Stock, and (ii) in the case of any series of cumulative Parity Stock, the aggregate of the current and accumulated and unpaid dividends due on such series of Parity Stock.

(f)   Holders of Series B Preferred Stock shall fully participate, on an as-converted basis, in any dividends declared and paid or distributions on Class A Common Stock as if the Series B Preferred Stock were converted into shares of Class A Common Stock as of the record date for such dividend or distribution, at the Conversion Rate in effect on such record date.

(a)   Prior to conversion pursuant to Section 7, in the event of a liquidation (complete or partial), dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary (a “Liquidation”), after payment or provision for payment of the debts and other liabilities of the Corporation, the holders of Series B Preferred Stock shall be entitled to receive, in respect of any shares of Series B Preferred Stock held by them, out of assets of the Corporation available for distribution to stockholders of the Corporation or their assignees, and subject to the

rights of any outstanding shares of Senior Stock and before any amount shall be distributed to the holders of Junior Stock, a liquidating distribution (the “Liquidation Distribution”) in an amount equal to the greater of (i) the then-applicable Liquidation Preference, including, for the avoidance of doubt, any adjustment for a PIK Accrual, and (ii) the amount such holder of Series B Preferred Stock would have been entitled to receive had such holder converted its shares of Series B Preferred Stock into shares of Class A Common Stock at the then-applicable Conversion Ratio immediately prior to such Liquidation. The “Liquidation Preference” shall equal $1,000 per share of Series B Preferred Stock, which amount shall be adjusted as the result of any PIK Accrual and as otherwise set forth herein. If, upon a Liquidation, the assets of the Corporation, or proceeds thereof, distributable among the holders of the then outstanding shares of Series B Preferred Stock and the holders of any shares of Parity Stock ranking on a parity with the Series B Preferred Stock with respect to any distribution of assets upon Liquidation are insufficient to pay in full the amount of all such Liquidation Preference payable with respect to the Series B Preferred Stock and any such Parity Stock, then the holders of Series B Preferred Stock and such Parity Stock shall share ratably in any distribution of assets in proportion to the full respective preferential amounts to which they are entitled.

(b)  The Corporation shall provide the holders of Series B Preferred Stock appearing on the stock books of the Corporation as of the date of such notice at the address of said holder shown therein with written notice of (i) any voluntary Liquidation promptly after such Liquidation has been approved by the Board of Directors and at least five (5) days prior to the effective date of such Liquidation and (ii) any involuntary Liquidation promptly upon the Corporation becoming aware of any instituted proceeding in respect thereof. Such notice shall state a distribution or payment date, the amount of the Liquidation Preference and the place where the Liquidation Preference shall be distributable or payable.

(c)   After the payment in cash or proceeds to the holders of shares of the Series B Preferred Stock of the full amount of the Liquidation Distribution with respect to outstanding shares of Series B Preferred Stock, the holders of outstanding shares of Series B Preferred Stock shall have no right or claim, based on their ownership of shares of Series B Preferred Stock, to the remaining assets of the Corporation, if any. Whenever any such distribution shall be paid in property other than cash, the value of such distribution shall be the fair market value of such property as determined in the good faith reasonable discretion of the Board of Directors or liquidating trustee, as the case may be.

(a)   General. Except as otherwise required by the General Corporation Law, other applicable law, the Certificate of Incorporation, or this Certificate of Designations, holders of Series B Preferred Stock shall not be entitled to any vote on matters submitted to the Corporation’s stockholders for approval. In any case in which the holders of the Series B Preferred Stock shall be entitled to vote pursuant to the General Corporation Law, other applicable law, the Certificate of Incorporation, or this Certificate of Designations, each holder of Series B Preferred Stock entitled to vote with respect to such matter shall be entitled to one vote per share of Series B Preferred Stock.

(b)  Protective Provisions. In addition to any vote required by the General Corporation Law, other applicable law, the Certificate of Incorporation, or this Certificate of Designations, for so long as any of the shares of Series B Preferred Stock shall remain outstanding, the Corporation shall not, either directly or indirectly by amendment, merger, consolidation or otherwise, take any of the following actions, including whether by amendment, merger, consolidation or otherwise, without (in addition to any other vote required by the General Corporation Law, other applicable law, the Certificate of Incorporation, or this Certificate of Designations), the written consent or affirmative vote of the holders of at least sixty-five percent (65%) of the then outstanding shares of Series B Preferred Stock voting as a separate class to:

(i)    authorize or create, or increase the authorized amount of, or issue any class or series of Senior Stock, or reclassify or amend the provisions of any existing class of securities of the Corporation into shares of Senior Stock;

(ii)   authorize, create or issue any stock or debt instrument or other obligation that is convertible or exchangeable into shares of its Senior Stock (or that is accompanied by options or warrants to purchase such Senior Stock);

(iii)   amend, alter or repeal any provision of the Certificate of Incorporation or this Certificate of Designations, in either case, in a manner that adversely affects the rights, preferences, privileges or powers of the Series B Preferred Stock;

(iv)    declare or pay any dividends or other distributions in cash or property with respect to its Capital Stock (other than dividends or other distributions of cash or property paid on the Series B Preferred Stock or Parity Stock in accordance with their respective certificates of designation);

(v)  redeem, repurchase, recapitalize or acquire shares of its Class A Common Stock or other Junior Stock (other than with respect to customary repurchase rights or tax withholding arrangements with respect to equity awards or benefit plans and the exchange of outstanding warrants consistent with past practice or as contemplated by the Certificate of Incorporation as in effect on the date hereof with respect to the Class B Common Stock);

(vi)    redeem, repurchase, recapitalize or acquire shares of its Parity Stock other than (A) pro rata offers to purchase all, or a pro rata portion, of the Series B Preferred Stock and such Parity Stock, (B) as a result of a reclassification of Parity Stock for or into other Parity Stock, (C) the exchange or conversion of Parity Stock for or into other Parity Stock or Junior Stock, (D) the purchase of fractional interests in shares of Parity Stock pursuant to the conversion or exchange provisions of such Parity Stock or the security being converted or exchanged or (E) in accordance with mandatory redemption obligations set forth in their respective certificates of designation; or

(vii)     notwithstanding anything to the contrary herein, repurchase, recapitalize or acquire shares of its Capital Stock in a transaction that would be treated, in whole or in part, as a dividend for U.S. federal income tax purposes (unless such redemption, repurchase, recapitalization or acquisition, based on the Corporation’s reasonable

determination, is an isolated transaction within the meaning of U.S. Treasury Regulations Section 1.305-3(b)(3) or is in connection with a Change of Control).

If the Corporation shall propose to take any action enumerated above in clauses (i) through (vii) of this Section 4(b) then, and in each such case, the Corporation shall give notice of such proposed action to each holder of record of the shares of Series B Preferred Stock appearing on the stock books of the Corporation as of the date of such notice at the address of said holder shown therein. Such notice shall specify, inter alia (x) the proposed effective date of such action; (y) the date on which a record is to be taken for the purposes of such action, if applicable; and (z) the other material terms of such action. Such notice shall be given at least ten (10) calendar days prior to the applicable date or effective date specified above. For the purposes of this Certificate of Designations, “Business Day” shall mean each day that is not a Saturday, Sunday or other day on which banking institutions in Houston, Texas or New York, New York are authorized or required by law to close. If at any time the Corporation shall cancel any of the proposed actions for which notice has been given under this Section 4(b) prior to the consummation thereof, the Corporation shall give prompt notice of such cancellation to each holder of record of the shares of Series B Preferred Stock appearing on the stock books of the Corporation as of the date of such notice at the address of said holder shown therein. For the avoidance of doubt, if a holder of record of shares of Series B Preferred Stock does not respond to the aforementioned notice, such non-response shall in no way be deemed to constitute the written consent or affirmative vote of such holder regarding any of the aforementioned actions in this Section 4(b) or described within such notice.

(a)   At any time that any Series B Preferred Stock is outstanding, the Corporation shall from time to time take all lawful action within its control to cause the authorized capital stock of the Corporation to include a number of authorized but unissued shares of Class A Common Stock equal to the Conversion Ratio multiplied by the number of shares of outstanding Series B Preferred Stock, which equals 71,590,909 shares as of the date hereof (the “Authorized Share Amount”) (for the avoidance of doubt, taking into account any other obligations of the Corporation to reserve Class A Common Stock upon the conversion, exchange or exercise of other securities of the Corporation, including, without limitation, any warrants to acquire shares of Class A Common Stock, such that any other reservation may not be counted toward the reservation of Class A Common Stock hereunder).

(b)  If (i) the Class A Common Stock is listed on a national securities exchange and (ii) any shares of Class A Common Stock to be reserved for the purpose of conversion of the Series B Preferred Stock require registration or listing with or approval of any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered upon conversion, then the Corporation shall, at its sole cost and expense, in good faith and as expeditiously as possible, endeavor to secure such registration, listing or approval, as the case may be.

(a)  The Series B Preferred Stock shall be evidenced by certificates in such form as the Board of Directors may approve and, subject to the satisfaction of any applicable legal, regulatory

and contractual requirements, may be assigned or transferred in a manner identical to the assignment and transfer of other stock; unless and until the Board of Directors determines to assign the responsibility to another person, Continental Stock Transfer & Trust Company will act as the registrar and transfer agent for the Series B Preferred Stock. The certificates evidencing Series B Preferred Stock shall be separately identified and shall not bear the same CUSIP number as the certificates evidencing Class A Common Stock or Class B Common Stock, or any other security of the Corporation.

(b)  The certificate(s) representing the Series B Preferred Stock may be imprinted with a legend in substantially the following form:

“THE SECURITIES IDENTIFIED HEREIN HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THESE SECURITIES NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.”

(a)   Each holder of Series B Preferred Stock shall have the option from time to time, exercisable by delivery of written notice to the Corporation substantially in the form attached hereto as Annex A-1 (the “Conversion Notice”), to convert all or a portion of such holder’s shares of Series B Preferred Stock into Class A Common Stock at the Conversion Ratio (an “Optional Holder Conversion”); provided that the Corporation shall not be required to honor such request if (i) such holder has previously delivered a Conversion Notice, in respect of an Optional Holder Conversion, during the same fiscal quarter or (ii) such Optional Holder Conversion does not involve an underlying conversion value of Class A Common Stock of at least $1,000,000 based on the Liquidation Preference on the date of the Conversion Notice (unless such lesser amount relates to all of a holder’s and its affiliates’ Series A Preferred Stock). The “Conversion Ratio” means, for each share of Series B Preferred Stock, the quotient of (i) the Liquidation Preference as of the date of the conversion and (ii) the then applicable Conversion Price. The “Conversion Price” shall initially be $0.308, which may be adjusted from time to time as set forth herein.

(b)  Following the third anniversary of the Issuance Date, if (i) the closing price of the Class A Common Stock reported by the principal national securities exchange on which the Class A Common Stock is then listed for trading (the “National Securities Exchange”) is greater than one hundred thirty percent (130%) of the Conversion Price for twenty (20) trading days during any (30) consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which the Corporation provides the Issuer Conversion Notice as set forth below (the “Measurement Period”), (ii) the average daily trading volume of the Class A Common Stock on the National Securities Exchange exceeded 250,000 for twenty (20) trading days during the Measurement Period (including the last day of such period) and (iii) the Corporation has an effective registration statement on file with the Securities and Exchange Commission covering resales of the underlying Class A Common Stock to be received upon any such conversion, then the Corporation shall have the option from time to

time, exercisable by delivery of written notice to the record holders of the shares of Series B Preferred Stock as of the date of such notice at the address of said holder shown on the stock books of the Corporation substantially in the form attached hereto as Annex A-2 (the “Issuer Conversion Notice”), to convert some or all of the outstanding shares of Series B Preferred Stock into Class A Common Stock at the Conversion Ratio (an “Issuer Forced Conversion”) on a date specified in the Issuer Conversion Notice that is no later than the second Business Day following such Issuer Conversion Notice. If the Corporation elects to cause less than all the outstanding shares of the Series B Preferred Stock to be converted, the Corporation shall select the Series B Preferred Stock to be converted from each holder of Series B Preferred Stock appearing on the stock books of the Corporation on a pro rata basis. This Section 7(b) shall have no force and effect during any period in which the Class A Common Stock is not listed on any national securities exchange (such time, a “Delisted Period”).

(c)  [Reserved.]

(d)  For so long as (x) the Term Loan Credit Agreement is in effect, upon the occurrence of a Change of Control prior to the one hundred eighty first (181st) day following the Term Loan Maturity Date (as defined in the Term Loan Credit Agreement in effect as of the date hereof) and prior to a Repayment Event (as defined in the Term Loan Credit Agreement) and (y) the ABL Credit Agreement is in effect, upon the occurrence of a Change of Control prior to the one hundred eighty first (181st) day following the Maturity Date (as defined in the ABL Credit Agreement in effect on the date hereof) and the repayment in full of the Obligations and termination of all Commitments (as each term is defined in the ABL Credit Agreement in effect as of the date hereof), the Corporation shall have the option, exercisable by delivery of an Issuer Conversion Notice at least one Business Day prior to such Change of Control, to convert on a date specified in such Issuer Conversion Notice no later than the second Business Day following such Issuer Conversion Notice some or all of the outstanding shares of Series B Preferred Stock into Class A Common Stock at the Conversion Ratio as of the date of such conversion (such a conversion, a “CoC Forced Conversion”); provided, however, that if in connection with the consummation of any CoC Forced Conversion pursuant to this Section 7(d) or Section 8(b)(ii) or Section 8(b)(iii) below the Conversion Ratio applicable to such conversion is less than the quotient of (i) the Liquidation Preference for such Series B Preferred Stock as of the date of such conversion and (ii) either (x) the volume-weighted average trading price of the Class A Common Stock on the National Securities Exchange for the thirty (30) trading day period (including the last day of such period) immediately preceding the date of such Issuer Conversion Notice or (y) if the CoC Forced Conversion occurs during a Delisted Period, then the Fair Market Value of the Class A Common Stock immediately preceding the date of such Issuer Conversion Notice, then in addition to any vote required by the General Corporation Law, other applicable law, the Certificate of Incorporation, or this Certificate of Designations, for so long as any of the shares of Series B Preferred Stock remain outstanding, the Corporation shall not take any affirmative action to approve or consummate such Change of Control without either the written consent or affirmative vote of the holders of a majority of the outstanding shares of Series B Preferred Stock voting as a separate class.

(e)   In the event a holder of shares of the Series B Preferred Stock has elected an Optional Holder Conversion pursuant to Section 7(a), or in the event the Corporation has elected an Issuer Forced Conversion pursuant to Section 7(b) above or a CoC Forced Conversion pursuant

to Section 7(d) above or Section 8(b)(ii) or Section 8(b)(iii), the Corporation shall deliver, no later than two Business Days following the conversion date, a number of shares of Class A Common Stock equal to the Conversion Ratio.

(f)   Any Class A Common Stock delivered as a result of conversion pursuant to this Section 7 shall be validly issued, fully paid and non-assessable, free and clear of any preemptive right, liens, claims, rights or encumbrances other than those arising under the General Corporation Law, the Amended and Restated Bylaws of the Corporation or, if a conversion occurs during a Delisted Period, transfer restrictions under the Securities Act and state securities laws. Immediately following the settlement of any conversion, if any, the rights of the holders of converted Series B Preferred Stock shall cease and the persons entitled to receive shares of Class A Common Stock upon the conversion of shares of Series B Preferred Stock shall be treated for all purposes as having become the owners of such shares of Class A Common Stock. Concurrently with such conversion, the converted shares of Series B Preferred Stock shall cease to be outstanding, shall be canceled and the shares of Series B Preferred Stock formerly designated pursuant to this Certificate of Designations shall be restored to authorized but unissued shares of Preferred Stock.

(g)  If, after the Issuance Date, the Corporation (i) makes a distribution on its Class A Common Stock in cash, securities (including Class A Common Stock) or other property or assets, (ii) subdivides or splits its outstanding Class A Common Stock into a greater number of Class A Common Stock, (iii) combines or reclassifies its Class A Common Stock into a smaller number of Class A Common Stock or (iv) issues by reclassification of its Class A Common Stock any securities (including any reclassification in connection with a merger, consolidation or business combination in which the Corporation is the surviving person or another constituent corporation is issuing equity securities in exchange for Class A Common Stock), then the Conversion Price in effect at the time of the record date for such distribution or of the effective date of such subdivision, split, combination, or reclassification shall be proportionately adjusted so that the conversion of the Series B Preferred Stock after such time shall entitle the holder to receive the aggregate number of Class A Common Stock (or shares of any securities into which such shares of Class A Common Stock would have been combined, consolidated, merged, reclassified or exchanged pursuant to clauses (iii) and (iv) above) that such holder would have been entitled to receive if the Series B Preferred Stock had been converted into Class A Common Stock immediately prior to such record date or effective date, as the case may be, and in the case of a merger, consolidation or business combination in which the Corporation is the surviving person or another constituent corporation is issuing equity securities in exchange for Class A Common Stock, the Corporation shall provide effective provisions to ensure that the provisions in this Certificate of Designations relating to the Series B Preferred Stock shall not be abridged or amended and that the Series B Preferred Stock shall thereafter retain the same powers, preferences and relative participating, optional and other special rights, and the qualifications, limitations and restrictions thereon, that the Series B Preferred Stock had immediately prior to such transaction or event either in the Corporation if the surviving corporation or in the constituent corporation. An adjustment made pursuant to this Section 7(g) shall become effective immediately after the record date in the case of a distribution and shall become effective immediately after the effective date in the case of a subdivision, combination, reclassification (including any reclassification in connection with a merger, consolidation or business combination in which the Corporation is the surviving person or a

constituent corporation) or split. Such adjustment shall be made successively whenever any event described above shall occur.

(h)  At least fifteen (15) days prior to the consummation of any recapitalization, reorganization, consolidation, Change of Control, spin-off or other business combination (not otherwise addressed in Section 7(g) above) (a “Corporation Event”), the Corporation shall notify each holder of Series B Preferred Stock of such event (such notice to set forth in reasonable detail the material terms and conditions of such Corporation Event and the securities, cash or other assets, if any, which a holder of Series B Preferred Stock and Class A Common Stock (each on a per share basis) would receive upon the consummation of such event, to the extent known by the Corporation at the time); provided that the Corporation shall not be obligated to provide any holder with information that is otherwise not publicly available.

(i)  Notwithstanding any of the other provisions of this Section 7, no adjustment shall be made to the Conversion Price pursuant to Section 7(g) as a result of any of the following:

(i)   the grant of Class A Common Stock or options, warrants or rights to purchase Class A Common Stock to employees, officers or directors of the Corporation or its subsidiaries, under compensation plans and agreements approved in good faith by the Board of Directors; provided, that in the case of options, warrants or rights to purchase Class A Common Stock, the exercise price per Class A Common Stock shall not be less than the closing price of the Class A Common Stock (as reported by the National Securities Exchange) or, during a Delisted Period, the Fair Market Value, on the date such option, warrant or other right is issued;

(ii)   the issuance of any Class A Common Stock as all or part of the consideration to effect (A) the closing of any acquisition by the Corporation of assets of a third party in an arm’s-length transaction or (B) the consummation of a merger, consolidation or other business combination of the Corporation with another entity in which the Corporation survives and the Class A Common Stock remain outstanding to the extent such transaction(s) is or are validly approved by the vote or consent of the Board of Directors;

(iii)   without duplication of Section 7(i)(i) above, the issuance of options, warrants or other rights to purchase Class A Common Stock, or securities exercisable or convertible into or exchangeable for Class A Common Stock (or options, warrants or other rights to purchase any such securities that are exercisable or convertible into or exchangeable for Class A Common Stock, in each case, that are outstanding on the Issuance Date (including, for the avoidance of doubt, the warrants exercisable for Class A Common Stock outstanding on the Issuance Date)); and

(iv)    the issuance of securities for which an adjustment is made under another provision of this Section 7.

(j)  Upon any adjustment to the Conversion Price pursuant to this Section 7, the Corporation promptly shall deliver to each holder of Series B Preferred Stock a certificate signed by an appropriate officer of the Corporation, setting forth in reasonable detail the event requiring

the adjustment and the method by which such adjustment was calculated and specifying the increased or decreased Conversion Price then in effect following such adjustment.

(k)   The Corporation shall pay any and all issue, documentary, stamp and other taxes, excluding any income, franchise, property or similar taxes, that may be payable in respect of any issue or delivery of Class A Common Stock on conversion of Series B Preferred Stock pursuant hereto. However, the holder of any Series B Preferred Stock shall pay any tax that is due because Class A Common Stock issuable upon conversion thereof are issued in a name other than such holder’s name.

(l)  No fractional Class A Common Stock shall be issued upon the conversion of any Series B Preferred Stock. All Class A Common Stock (including fractions thereof) issuable upon conversion of more than one share of Series B Preferred Stock by a holder thereof shall be aggregated for purposes of determining whether the conversion would result in the issuance of any fractional stock. If, after the aforementioned aggregation, the conversion would result in the issuance of a fraction of a Class A Common Stock, the Corporation shall not issue a fractional Class A Common Stock but shall round the fractional Class A Common Stock to the nearest whole Class A Common Stock (and a 0.5 of a share of Class A Common Stock shall be rounded up to the next higher share of Class A Common Stock).

(m)    The Corporation agrees that it will act in good faith to make any adjustment(s) required by this Section 7 equitably and in such a manner as to afford the holders of Series B Preferred Stock the benefits of the provisions hereof, and will not intentionally take any action to deprive such holders of the express benefit hereof.

(n)  Notwithstanding anything in this Section 7 to the contrary, if a proposed conversion would require approvals under, or conflict with, the terms of (i) the Senior Secured Term Loan Credit Agreement, dated May 7, 2019, by and among the Corporation, USWS Holdings, LLC, U.S. Well Services, LLC, the guarantors and initial lenders named therein and CLMG Corp, in effect as of the date hereof (the “Term Loan Credit Agreement”), or (ii) the terms of the ABL Credit Agreement dated as of May 7, 2019 among the Corporation, USWS Holdings, LLC, the lenders party thereto, Bank of America, N.A., as administrative agent, and the other parties thereto, in effect as of the date hereof (the “ABL Credit Agreement” and together with the Term Loan Credit Agreement, the “Credit Facilities”), such conversion shall be limited to the number of shares of Series B Preferred Stock that would not require any approvals or result in any conflicts.

(a)   Following eighteen (18) months after the Issuance Date, the Corporation has the option in its sole discretion, from time to time other than in connection with a Liquidation, to redeem all or a portion (but in no less than $1,000,000 increments based on the Liquidation Preference as of the date of the Redemption Notice (or such lesser amount to the extent the Redemption Notice relates to all of the outstanding shares of the Series B Preferred Stock)) of the then outstanding shares of Series B Preferred Stock, for an amount per share of Series B Preferred Stock equal to the Liquidation Preference as of the date of redemption (the “Redemption Price”), subject to a holder’s right to elect conversion set forth below. The Corporation may exercise its redemption option under this Section 8(a) by delivery of written notice to the holders of shares of

the Series B Preferred Stock in the form attached as Annex B (the “Redemption Notice”) , provided, however, that the holders of Series B Preferred Stock shall have five Business Days from the date of receipt of any such Redemption Notice to, in lieu of being paid the cash Redemption Price, elect to convert the shares of Series B Preferred Stock subject to such Redemption Note in accordance with Section 7(a). Such redemption shall be completed on a date specified in the Redemption Notice, which shall be not less than 10 and not more than 20 Business Days following the date of the Redemption Notice. If the Corporation redeems only a portion of the then outstanding shares of Series B Preferred Stock, the shares of Series B Preferred Stock subject to such redemption shall be allocated pro rata among the outstanding shares of Series B Preferred Stock.

(b)  Change of Control.

(i)    For so long as (x) the Term Loan Credit Agreement is in effect, upon the occurrence of a Change of Control prior to the one hundred eighty first (181st) day following the Term Loan Maturity Date (as defined in the Term Loan Credit Agreement in effect as of the date hereof) and prior to a Repayment Event (as defined in the Term Loan Credit Agreement) or (y) the ABL Credit Agreement is in effect, upon the occurrence of a Change of Control prior to the one hundred eighty first (181st) day following the Maturity Date (as defined in the ABL Credit Agreement in effect on the date hereof) and the repayment in full of the Obligations and termination of all Commitments (as each term is defined in the ABL Credit Agreement in effect as of the date hereof), at the option of the Corporation, either (A) the Corporation shall convert all or part of the outstanding Series B Preferred Stock pursuant to, and subject to any vote required by, Section 7(d) or (B) each holder of Series B Preferred Stock shall have their shares of Series B Preferred Stock redeemed in exchange for a cash payment per share of Series B Preferred Stock held by such holder equal to the greater of (1) the Liquidation Preference as of the date of such payment and (2) the amount such holder would have been entitled to receive in or as a result of such Change of Control pursuant to the applicable merger or other acquisition agreement if, immediately prior to the record date for payments relating to such Change of Control, such share of Series B Preferred Stock had been converted into a number of shares of Class A Common stock equal to the Conversion Ratio at such time (such cash payment, the “Change of Control Cash Redemption Amount”); provided, however, that if in connection with the determination and payment of any Change of Control Cash Redemption Amount pursuant to this Section 8(b)(i) or Section 8(b)(ii) or Section 8(b)(iii) below the Conversion Ratio applicable to such determination is less than the quotient of (i) the Liquidation Preference for such Series B Preferred Stock as of the date of such payment and (ii) either (x) the volume-weighted average trading price of the Class A Common Stock on the National Securities Exchange for the thirty (30) trading day period (including the last day of such period) immediately preceding the date of such payment or (y) if such Change of Control occurs during a Delisted Period, then the Fair Market Value of the Class A Common Stock immediately preceding the date of such payment, then in addition to any vote required by the General Corporation Law, other applicable law, the Certificate of Incorporation, or this Certificate of Designations, for so long as any of the shares of Series B Preferred Stock remain outstanding, the Corporation shall not take any affirmative action to approve or consummate such Change of Control without either the

written consent or affirmative vote of the holders of a majority of the outstanding shares of Series B Preferred Stock voting as a separate class.

(ii)   Upon the occurrence of (A) a Change of Control prior to the one hundred eightieth (180th) day following the Term Loan Maturity Date but after a Repayment Event or (B) a Change of Control at least one hundred eighty (180) days after the Term Loan Maturity Date, each holder of shares of Series B Preferred Stock shall, subject to any vote required under Section 8(b)(i), have their shares of Series B Preferred Stock redeemed in exchange for a cash payment per share of Series B Preferred Stock held by such holder equal to the Change of Control Cash Redemption Amount; provided, however, that if such redemption occurs during a Delisted Period and if the consideration issued to holders of the Class A Common Stock upon a Change of Control consists solely of (I) cash, (II) equity that is listed on a national securities exchange, or (III) a combination thereof, then, at the option of the Corporation, either (x) the Corporation shall, subject to any vote required under Section 8(b)(i), redeem all shares of Series B Preferred Stock by paying each holder a cash payment per share of Series B Preferred Stock held by such holder equal to the Change of Control Cash Redemption Amount or, (y) the Series B Preferred Stock shall, as of immediately prior to such Change of Control, and subject to any vote required under Section 7(d), convert into a number of shares of Class A Common Stock equal to the Conversion Ratio at such time (such a conversion, a “CoC Forced Conversion”).

(iii)    When the Term Loan Credit Agreement is not in effect, upon the occurrence of a Change of Control, each holder of shares of Series B Preferred Stock shall, subject to any vote required under Section 8(b)(i), have their shares of Series B Preferred Stock redeemed in exchange for a cash payment per share of Series B Preferred Stock held by such holder equal to the Change of Control Cash Redemption Amount; provided, however, that if such redemption occurs during a Delisted Period and if the consideration issued to holders of the Class A Common Stock upon a Change of Control consists solely of (I) cash, (II) equity that is listed on a national securities exchange, or (III) a combination thereof, then, at the option of the Corporation, either (x) the Corporation shall, subject to any vote required under Section 8(b)(i), redeem all shares of Series B Preferred Stock by paying each holder a cash payment per share of Series B Preferred Stock held by such holder equal to the Change of Control Cash Redemption Amount or, (y) the Series B Preferred Stock shall, as of immediately prior to such Change of Control, subject to any vote required under Section 7(d), convert into a number of shares of Class A Common Stock equal to the Conversion Ratio at such time (such a conversion, a “CoC Forced Conversion”).

(iv)  (A) a “Change of Control” means (1) the consummation of any transaction by the Corporation the result of which is that any person, other than any Permitted Holder, becomes the beneficial owner, directly or indirectly, of more than fifty percent (50%) of the voting stock of the Corporation, measured by voting power rather than number of shares, units or the like; provided that a transaction in which the Corporation becomes a subsidiary of another person shall not constitute a Change of Control if, immediately following such transaction, the persons who were beneficial owners of the voting stock of the Corporation immediately prior to such transaction beneficially own, directly or indirectly, fifty percent (50%) or more of the total voting power of the voting stock of such other person of whom the Corporation has become a subsidiary or (2) the sale of all or

substantially all of the Corporation’s assets; and (B) the “Permitted Holder” means any holder of shares of Series B Preferred Stock as of the Issuance Date and its affiliates.

(v)  “Fair Market Value” means the fair market value of the Class A Common Stock, as determined in good faith by the Board of Directors. Notwithstanding Section 7(h), the Corporation shall provide notice of the Board of Directors’ determination (together with reasonably supporting documentation as to such determination) as to Fair Market Value to each holder of the then outstanding shares of Series B Preferred Stock at least thirty (30) Business Days in advance of any Change of Control transaction that occurs during a Delisted Period and in which Fair Market Value is used (a “FMV Determination Notice”). Notwithstanding anything to the contrary in this clause (v), if the holders of at least seventy-five percent (75%) of the then outstanding shares of Series B Preferred Stock provide a written consent disputing the Board of Directors’ Fair Market Value determination (a “Dispute Notice”) within five (5) Business Days following delivery of a FMV Determination Notice, the Board of Directors and a holder of Series B Preferred Stock designated as the representative of the then outstanding shares of Series B Preferred Stock (the “Series B Representative”) shall attempt to agree on the Fair Market Value in good faith; provided, however, that if the Board of Directors and the Series B Representative are unable to agree upon the Fair Market Value within five (5) Business Days after delivery of a Dispute Notice, the Board of Directors and the Series B Representative shall submit the dispute to an internationally recognized independent investment bank or valuation firm selected by the Series B Representative from three such investment banks or valuation firms proposed by the Corporation (the “Independent Appraiser”). The Independent Appraiser’s determination as to the Fair Market Value shall be final, binding and conclusive for all purposes. The holders of the then outstanding shares of Series B Preferred Stock shall bear one hundred percent (100%) of the fees and expenses of the Independent Appraiser through a reduction in the Liquidation Preference of each share of Series B Preferred Stock that shall be equal to the quotient of the fees and expenses of the Independent Appraiser divided by the number of then outstanding shares of Series B Preferred Stock; provided, however, that if the appraised Fair Market Value as determined by the Independent Appraiser exceeds one hundred twenty-five percent (125%) of the Fair Market Value determined by the Board of Directors, no adjustment to the Liquidation Preference shall be made, and the Corporation shall pay one hundred percent (100%) of the fees and expenses of the Independent Appraiser.

(a)   In connection with any conversion pursuant to Section 7 or redemption in accordance with Section 8, the holder of Series B Preferred Stock must surrender the certificates, if any, representing such shares of Series B Preferred Stock (or, if such certificate or certificates have been lost, stolen, or destroyed, a lost certificate affidavit and indemnity in form and substance reasonably acceptable to the Corporation), and deliver transfer instruments reasonably satisfactory to the Corporation, at the principal office of the Corporation (or such other place mutually acceptable to the holder of Series B Preferred Stock and the Corporation). Upon surrender of a certificate that is to be redeemed or converted in part pursuant to this Certificate of Designation, the Corporation shall execute and deliver to the holder of such certificate a new certificate representing the number of Series B Preferred Stock that are not so redeemed or converted.

(b)  On the date of a conversion or redemption hereof, as applicable, with respect to any share of Series B Preferred Stock, certificates representing the number of shares of Class A Common Stock into which the applicable shares of Series B Preferred Stock are converted shall be promptly issued and delivered to the holder of Series B Preferred Stock thereof or such holder’s designee (or cash shall be paid to an account designated by such person) upon presentation and surrender of the certificate, if any, evidencing the Series B Preferred Stock (or, if such certificate or certificates have been lost, stolen, or destroyed, a lost certificate affidavit and indemnity in form and substance reasonably acceptable to the Corporation) to the Corporation and, if required, the furnishing of appropriate endorsements and transfer documents and the payment of all transfer and similar taxes, if any, allocable to such holder.

The shares of Series B Preferred Stock shall not have any powers, designations, preferences or relative, participating, optional, or other special rights, nor shall there be any qualifications, limitations or restrictions or any powers, designations, preferences or rights of such shares, other than as set forth herein or in the Certificate of Incorporation, or as may be provided by law.

(a)  The shares of Series B Preferred Stock shall not be subject to the operation of any retirement or sinking fund.

(b)  In case any one or more of the provisions contained in this Certificate of Designations shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. Furthermore, in lieu of any such invalid, illegal or unenforceable provision, there shall be added automatically as a part of this Certificate of Designations a provision as similar in terms to such invalid, illegal or unenforceable provision as may be possible and be legal, valid and enforceable, unless the requisite parties separately agree to a replacement provision that is valid, legal and enforceable.

(c)  Any payments, issuances or distributions required to be made hereunder on any day that is not a Business Day shall be made on the next succeeding Business Day without interest or additional payment for such delay. All payments required hereunder shall be made by wire transfer of immediately available funds in United States Dollars to the holders in accordance with the payment instructions as such holders may deliver by written notice to the Corporation from time to time.

This Certificate of Designations shall become effective on March 31, 2020.

A Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Shelf Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that a Shelf Registration Statement becomes effective, but in any event within five (5) Business Days of such date, USWS shall provide the Holders with written notice of the effectiveness of a Shelf Registration Statement.

(b)  Resale Registration Opt-Out. At least five (5) Business Days before the initial filing of the Shelf Registration Statement required by Section 2.1(a), USWS shall provide advance written notice to each Holder that it plans to file a Shelf Registration Statement. Any Holder may deliver advance written notice (a “Resale Opt-Out Notice”) to USWS requesting that such Holder not be included in a Shelf Registration Statement prior to its initial filing. Following receipt of a Resale Opt-Out Notice from a Holder, USWS shall not be required to include the Registrable Securities of such Holder in such Shelf Registration Statement.

(c)  Delay Rights. Notwithstanding anything to the contrary contained herein, USWS may, upon written notice to any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement) if (i) USWS is pursuing an acquisition, merger, reorganization, disposition or other similar transaction and USWS determines in good faith that USWS’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or (ii) USWS has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of USWS, would materially and adversely affect USWS; provided, however, that in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Shelf Registration Statement for a period of sixty (60) consecutive days or an aggregate of one-hundred and twenty (120) days in any 365-day period. Upon disclosure of such information or the termination of the condition described above,

USWS shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Shelf Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement.

(d)  Renewal. If, by the third anniversary (the “Renewal Deadline”) of the initial effective date of a Shelf Registration Statement filed pursuant to this Section 2.1, any of the Registrable Securities remain unsold by a Holder included on such Registration, USWS shall file, if it has not already done so and is eligible to do so, a new Shelf Registration Statement covering the Registrable Securities included on the prior Shelf Registration Statement and shall use its commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective within 180 days after the Renewal Deadline; and USWS shall take all other action necessary or appropriate to permit the public offering and sale of the Registrable Securities to continue as contemplated in the expired Shelf Registration Statement. References herein to Shelf Registration Statement shall include such new shelf registration statement.

Section 2.2 Piggyback Registration.

(a)  Participation. If at any time USWS proposes to file (i) at a time when USWS is not a WKSI, a registration statement and such Holder has not previously included its Registrable Securities in a Shelf Registration Statement contemplated by Section 2.1(a) of this Agreement that is currently effective, or (ii) a prospectus supplement to an effective “automatic shelf registration statement” (as defined in Rule 405 under the Securities Act), so long as USWS is a WKSI at such time or, whether or not USWS is a WKSI, so long as the Registrable Securities were previously included in the underlying Shelf Registration Statement or are included in an effective Shelf Registration Statement, or in any case in which Holders may participate in such offering without the filing of a post-effective amendment, in each case, for the sale of Class A Common Stock in an Underwritten Offering for its own account and/or another Person, other than (a) a registration relating solely to employee benefit plans, (b) a registration relating solely to a Rule 145 transaction, or (c) a registration statement on any registration form which does not permit secondary sales, then USWS shall give not less than three (3) Business Days advance notice (including, but not limited to, notification by e-mail; such notice, a “Piggyback Notice”) of such proposed Underwritten Offering to each Holder that, together with its Affiliates, owns more than $5.0 million of Registrable Securities, and such notice shall offer such Holder the opportunity to participate in any Underwritten Offering and to include in such Underwritten Offering such number of Registrable Securities (the “Included Registrable Securities”) as each such Holder may request in writing (a “Piggyback Registration”); provided, however, that USWS (A) shall not be required to include the Registrable Securities of the Holders in such Registration if the Holders do not offer a minimum of $5.0 million of Registrable Securities, or (B) if USWS has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the offering price, timing or probability of success of the distribution of the Class A Common Stock in the Underwritten Offering, then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.2(b). If USWS is not required to offer the opportunity for a Piggyback Registration in respect of a proposed Underwritten Offering as a result of the circumstance described in clause (B) of the proviso of the immediately preceding sentence, then USWS shall nevertheless be required to furnish to such Holders the Piggyback Notice in respect of such proposed Underwritten

Offering, which notice shall describe USWS’s intention to conduct an Underwritten Offering and, if the determination described in clause (B) of the proviso of the immediately preceding sentence has been made at the time that the Piggyback Notice is required to be given by USWS, shall include notification that the Holders do not have the opportunity to include Registrable Securities in such Underwritten Offering because USWS has been advised by the Managing Underwriter that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the offering price, timing or probability of success of the distribution of the Class A Common Stock in the Underwritten Offering. If the circumstance described in clause (B) of the proviso of the immediately preceding sentence is made after the Piggyback Notice has been given, then USWS shall notify the Holders who were provided such Piggyback Notice (or if the two Business Day period referred to in the next sentence has lapsed, the Holders who have timely elected to include Registrable Securities in such offering) in writing of such circumstance and the aggregate number of Registrable Securities, if any, that can be included in such offering. Each Piggyback Notice shall be provided to Holders on a Business Day pursuant to Section 3.1 hereof and confirmation of receipt of such notice shall be requested in the notice. The Holder will have two Business Days after notice has been delivered to request in writing the inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received within the specified time, such Holder shall have no further right to participate in such Piggyback Registration. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, USWS shall determine for any reason not to undertake or to delay such Underwritten Offering, USWS may, at its election, give written notice of such determination to the Selling Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Underwritten Offering by giving written notice to USWS of such withdrawal up to and including the time of pricing of such offering. Any Holder may deliver written notice (a “Piggyback Opt-Out Notice”) to USWS requesting that such Holder not receive notice from USWS of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any such Piggyback Opt-Out Notice in writing. Following receipt of a Piggyback Opt-Out Notice from a Holder (unless subsequently revoked), USWS shall not be required to deliver any notice to such Holder pursuant to this Section 2.2(a) and such Holder shall no longer be entitled to participate in Underwritten Offerings by USWS pursuant to this Section 2.2(a), unless such Piggyback Opt-Out Notice is revoked by such Holder.

(b)  Priority of Piggyback Registration. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering of shares of Class A Common Stock included in a Piggyback Registration advises USWS that the total shares of Class A Common Stock which the Selling Holders and any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have an adverse effect on the offering price, timing or probability of success of the distribution of the Class A Common Stock offered or the market for the Class A Common Stock, then the Piggyback Notice provided by USWS pursuant to Section 2.2(a) shall include notification of such determination or, if such determination is made after the Piggyback Notice has been given, then USWS shall furnish notice in writing (including by e-mail) to the Holders (or to those who have timely elected to participate in such Underwritten

Offering), and the Class A Common Stock to be included in such Underwritten Offering shall include the number of shares of Class A Common Stock that such Managing Underwriter or Underwriters advises USWS can be sold without having such adverse effect, with such number to be allocated (i) if such Piggyback Registration was initiated by USWS, (A) first, to USWS, (B) second, pro rata among the Selling Holders and any other Persons who have been or after the date hereof are granted registration rights on parity (including pursuant to the Existing Preferred RRA) with the registration rights granted under this Agreement (the “Other Holders”) who have requested participation in the Piggyback Registration (based, for each such Selling Holder or Other Holder, on the percentage derived by dividing (1) the number of shares of Class A Common Stock proposed to be sold by such Selling Holder or such Other Holder in such offering; by (2) the aggregate number of shares of Class A Common Stock proposed to be sold by all Selling Holders and all Other Holders in the Piggyback Registration), and (C) third, to any other holder of shares of Class A Common Stock with registration rights that are subordinate to the rights of the Holders hereunder and (ii) if such Piggyback Registration was not initiated by USWS, (A) first, to the Persons initiating such Registration, (B) second, pro rata among the Selling Holders and any Other Holders who have requested participation in the Piggyback Registration (based, for each such Selling Holder or Other Holder, on the percentage derived by dividing (1) the number of shares of Class A Common Stock proposed to be sold by such Selling Holder or such Other Holder in such offering; by (2) the aggregate number of shares of Class A Common Stock proposed to be sold by all Selling Holders and all Other Holders in the Piggyback Registration other than the Persons initiating such Registration), except that in the case of a Shelf Underwritten Offering (as defined in the Registration Rights Agreement of USWS dated November 9, 2018 (the “Existing RRA”)) the Holders shall only be permitted to participate in such Shelf Underwritten Offering after all of the securities that Other Holders have requested to be included in such Shelf Underwritten Offering pursuant to the Existing RRA have been so included, and (C) third, to any other holder of shares of Class A Common Stock with registration rights that are subordinate to the rights of the Holders hereunder.

Section 2.3 Secondary Underwritten Offering.

(a)  S-3 Registration. In the event that a Selling Holder (together with any Affiliates that are Selling Holders) elects to dispose of Registrable Securities under the Shelf Registration Statement pursuant to an Underwritten Offering for its own account of at least $10.0 million, such Selling Holder shall give notice of such election in writing (including, but not limited to, notification by e-mail; such notice, the “Selling Holder Election Notice”) to USWS not less than twenty (20) Business Days before the date such Selling Holder intends for such Underwritten Offering to commence marketing (whether on a confidential basis or on a public basis); provided that USWS shall not be required to conduct more than two Underwritten Offerings pursuant to this Section 2.3 in any 365-day period pursuant to Selling Holder Election Notices. The Selling Holder Election Notice shall specify the number of Registrable Securities that the Selling Holder intends to offer in such Underwritten Offering and the expected commencement date thereof. USWS shall, at the request of such Selling Holder, enter into an underwriting agreement in customary form with the Managing Underwriter or Underwriters, which shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.8, and shall take all such other reasonable actions as are requested by the Managing Underwriter in order to expedite or facilitate the disposition of the Registrable Securities.

(b)  Notice to Holders. Not later than two (2) Business Days after receipt by USWS of the Selling Holder Election Notice, unless USWS determines in accordance with Section 2.1(c) to delay such Underwritten Offering (in which event USWS shall promptly notify the initiating Selling Holder in writing of such determination), then USWS shall provide written notice (including, but not limited to, notification by e-mail) to the other Holders of Registrable Securities of the Selling Holder’s intention to conduct an Underwritten Offering and such notice shall offer such other Holders the opportunity to participate in such Underwritten Offering and to include in such Underwritten Offering such number of Registrable Securities as each such Holder may request in writing. Each such other Holder will have five (5) Business Days after notice has been delivered to request in writing submitted to USWS the inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received by USWS within the specified time, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, the Selling Holder giving the notice shall determine for any reason not to undertake or to delay such Underwritten Offering, such Selling Holder may, at its election, give written notice of such determination to USWS and USWS shall notify the other Holders and, (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to include Registrable Securities of any other Holder, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Registrable Securities of any other Holder for the same period as the delay in the Underwritten Offering. Any other Holder shall have the right to withdraw such Holder’s request for inclusion of such Holder’s Registrable Securities in such Underwritten Offering by giving written notice to USWS of such withdrawal up to and including the time of pricing of such offering. If the Managing Underwriter or Underwriters of any proposed Underwritten Offering of Registrable Securities under a Shelf Registration Statement advises USWS that the total amount of Registrable Securities which the Selling Holders and any other Persons intend to include in such offering exceeds the number which can be sold in such offering without being likely to have an adverse effect on the offering price, timing or probability of success of the distribution of the Registrable Securities offered or the market for the Registrable Securities, then the Registrable Securities to be included in such Underwritten Offering shall include the number of Registrable Securities that such Managing Underwriter or Underwriters advises USWS can be sold without having such adverse effect, with such number to be allocated pro rata among the Selling Holders and the other Holders who have requested participation in the Underwritten Offering (based, for each such Selling Holder or other Holder, on the percentage derived by dividing (A) the number of Registrable Securities proposed to be sold by such Selling Holder or such other Holder in such offering; by (B) the aggregate number of Registrable Securities proposed to be sold by all Selling Holders and all other Holders in such Underwritten Offering).

Section 2.4 Sale Procedures.

(a)  General Procedures. In connection with any Underwritten Offering (i) under Section 2.2 or Section 2.13 of this Agreement, USWS shall be entitled to select the Managing Underwriter or Underwriters, and (ii) under Section 2.3 of this Agreement, the Selling Holders shall be entitled to select the Managing Underwriter or Underwriters. In connection with an Underwritten Offering contemplated by this Agreement in which a Selling Holder participates, each Selling Holder and USWS shall be obligated to enter into an underwriting agreement with the Managing Underwriter or Underwriters which contains such representations, covenants,

indemnities and other rights and obligations as are customary in underwriting agreements for firm commitment offerings of equity securities. No Selling Holder may participate in such Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each Selling Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, USWS to and for the benefit of such underwriters also be made to and for such Selling Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations. No Selling Holder shall be required to make any representations or warranties to or agreements with USWS or the underwriters other than representations, warranties or agreements regarding such Selling Holder’s ownership of the securities being registered on its behalf and its intended method of distribution and any other representation required by law. If any Selling Holder disapproves of the terms of an underwriting, such Selling Holder may elect to withdraw therefrom by notice to USWS and the Managing Underwriter; provided, however, that such withdrawal must be made at least one Business Day prior to the time of pricing of such Underwritten Offering to be effective. No such withdrawal or abandonment shall affect USWS’s obligation to pay Registration Expenses. Upon the receipt by USWS of a written request from the Holders of at least $10.0 million dollars of Registrable Securities that are participating in any Underwritten Offering contemplated by this Agreement, USWS’s management shall be required to participate in a roadshow or similar marketing effort in connection with any Underwritten Offering.

(b)  In connection with its obligations under this Article II, USWS will, as expeditiously as possible:

(i)  prepare and file with the Commission such amendments and supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to keep a Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by a Shelf Registration Statement;

(ii)  if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering from a Shelf Registration Statement and the Managing Underwriter at any time shall notify USWS in writing that, in the sole judgment of such Managing Underwriter, the inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of the Underwritten Offering of such Registrable Securities, USWS shall use its commercially reasonable efforts to include such information in the prospectus supplement;

(iii)  furnish to each Selling Holder (A) as far in advance as reasonably practicable before filing a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of

distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing such Shelf Registration Statement or such other registration statement and the prospectus included therein or any supplement or amendment thereto, and (B) such number of copies of such Shelf Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by such Shelf Registration Statement or other registration statement;

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

(v)  promptly notify each Selling Holder and each underwriter, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (A) the filing of a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus included therein or any amendment or supplement thereto (other than any amendment or supplement resulting from the filing of a document incorporated by reference therein), and, with respect to such Shelf Registration Statement or any other registration statement or any post-effective amendment thereto, when the same has become effective; and (B) the receipt of any written comments from the Commission with respect to any filing referred to in clause (A) and any written request by the Commission for amendments or supplements to such Shelf Registration Statement or any other registration statement or any prospectus or prospectus supplement thereto;

(vi)  immediately notify each Selling Holder and each underwriter, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (A) the happening of any event as a result of which the prospectus contained in a Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplemental amendment thereto, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (B) the issuance or threat of issuance by the Commission of any stop order suspending the effectiveness of such Shelf Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (C) the receipt by USWS of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, USWS agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the

circumstances then existing and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(vii)  upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(viii)  in the case of an Underwritten Offering, furnish upon request, (A) an opinion of counsel for USWS, dated the effective date of the applicable registration statement or the date of any amendment or supplement thereto (other than any amendment or supplement resulting from the filing of a document incorporated by reference therein), preliminary or prospectus supplement, and a letter of like kind dated the date of the closing under the underwriting agreement, and (B) a “comfort” letter, dated the pricing date of such Underwritten Offering and a letter of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants who have certified USWS’s financial statements included or incorporated by reference into the applicable registration statement, and each of the opinion and the “comfort” letter shall be in customary form and covering substantially the same matters with respect to such registration statement (and the prospectus included therein and any supplement thereto) and as are customarily covered in opinions of issuer’s counsel and in accountants’ letters delivered to the underwriters in underwritten offerings of securities, such other matters as such underwriters may reasonably request;

(ix)  except during a Going Dark Period, otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(x)  make available to the appropriate representatives of the underwriters access to such information and USWS personnel as is reasonable and customary to enable such parties and their representatives to establish a due diligence defense under the Securities Act; provided that USWS need not disclose any non-public information to any such representative unless and until such representative has entered into a confidentiality agreement with USWS;

(xi)  cause all such Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by USWS are then listed;

(xii)  use its commercially reasonable efforts to cause the Registrable Securities to be registered with or approved by such other governmental agencies or authorities as

may be necessary by virtue of the business and operations of USWS to enable the Selling Holders to consummate the disposition of such Registrable Securities;

(xiii)  provide a transfer agent and registrar for all Registrable Securities covered by such registration statement; and

(xiv)  enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities.

(c)  Each Selling Holder, upon receipt of notice from USWS of the happening of any event of the kind described in Section 2.4(b)(vi), shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.4(b)(vi) or until it is advised in writing by USWS that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by USWS, such Selling Holder will, or will request the Managing Underwriter or underwriters, if any, to deliver to USWS (at USWS’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus and any prospectus supplement covering such Registrable Securities current at the time of receipt of such notice.

Section 2.5 Cooperation by Holders. USWS shall have no obligation to include Registrable Securities of a Holder in the Shelf Registration Statement, IPO Registration Statement or in an Underwritten Offering under Article II of this Agreement if such Selling Holder has failed to timely furnish such information which, in the opinion of counsel to USWS, is reasonably required in order for the registration statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.6 Restrictions on Public Sale by Holders of Registrable Securities. For a period of one year following the Effective Date, each Holder of Registrable Securities who is included in the Shelf Registration Statement agrees not to effect any public sale or distribution of the Registrable Securities during the forty-five (45) calendar day period beginning on the date of a prospectus supplement filed with the Commission with respect to the pricing of an Underwritten Offering, or other prospectus (including any free writing prospectus) containing the terms of the pricing of such Underwritten Offering; provided that (a) USWS gives written notice to such Holder of the date of the commencement and termination of such period with respect to any such Underwritten Offering and (b) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters on the officers or directors or any other stockholder of USWS on whom a restriction is imposed; and provided further that this Section 2.6 shall only be applicable to Holders of Registrable Securities included in the Shelf Registration Statement who (together with their Affiliates that hold Registrable Securities) (y) own at least $5.0 million of Registrable Securities and (z) have not delivered (or delivered and subsequently revoked) a Piggyback Opt-Out Notice.

Section 2.7 Expenses.

(a)  Certain Definitions. “Registration Expenses” means all expenses incident to USWS’s performance under or compliance with this Agreement to effect the registration of Registrable Securities in a Shelf Registration Statement pursuant to Section 2.1, a Piggyback Registration pursuant to Section 2.2, an Underwritten Offering pursuant to Section 2.3 or an IPO Registration Statement pursuant to Section 2.13 and the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing and fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, transfer taxes and fees of transfer agents and registrars, all word processing, duplicating and printing expenses, all roadshow expenses borne by it and the fees and disbursements of counsel and independent public accountants for USWS, including the expenses of any special audits or “comfort” letters required by or incident to such performance and compliance. Except as otherwise provided in Section 2.8 hereof, USWS shall not be responsible for legal fees incurred by Holders in connection with the exercise of such Holders’ rights hereunder. In addition, USWS shall not be responsible for any “Selling Expenses,” which means all underwriting fees, discounts and selling commissions, transfer taxes and fees of counsel allocable to the sale of the Registrable Securities.

(b)  Expenses. USWS will pay all reasonable Registration Expenses in connection with a Shelf Registration Statement, a Piggyback Registration, an IPO Registration Statement or Underwritten Offering, whether or not any sale is made pursuant to such Shelf Registration Statement, Piggyback Registration or Underwritten Offering. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of its Registrable Securities hereunder.

Section 2.8 Indemnification.

(a)  By USWS. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, USWS will indemnify and hold harmless each Selling Holder thereunder, its directors, officers, employees, agents and managers, and each underwriter, pursuant to the applicable underwriting agreement with such underwriter, of Registrable Securities thereunder and each Person, if any, who controls such Selling Holder or underwriter within the meaning of the Securities Act and the Exchange Act, and its directors, officers, employees, agents and managers, against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder or underwriter or controlling Person or directors, officers, employees, agents or managers may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus or final prospectus contained therein, or any free writing prospectus related thereto, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading, and will

reimburse each such Selling Holder, its directors and officers, each such underwriter and each such controlling Person and each such director, officer, employee, agent or manager for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that USWS will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished by such Selling Holder, such underwriter or such controlling Person in writing specifically for use in the Shelf Registration Statement or such other registration statement, or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer, employee, agent, manager or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b)  By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless USWS, its directors, officers, employees and agents and each Person, if any, who controls USWS within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from USWS to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement, any other registration statement contemplated by this Agreement or prospectus supplement relating to the Registrable Securities, or any amendment or supplement thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds (net of any Selling Expenses) received by such Selling Holder from the sale of the Registrable Securities giving rise to such indemnification less the amount of any damages that such Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.

(c)  Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party other than under this Section 2.8(c) except to the extent that the indemnifying party is materially prejudiced by such failure. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.8 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel reasonably satisfactory to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party or representation by both parties by the same

counsel is otherwise inappropriate under the applicable standards of professional conduct, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, 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, includes a complete release from liability of, and does not contain any admission of wrong doing by, the indemnified party.

(d)  Contribution. If the indemnification provided for in this Section 2.8 is held by a court or government agency of competent jurisdiction to be unavailable to USWS or any Selling Holder or is insufficient to hold them harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of USWS on the one hand and of such Selling Holder on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification less the amount of any damages that such Selling Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The relative fault of USWS on the one hand and each Selling Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e)  Other Indemnification. The provisions of this Section 2.8 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.9 Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Registrable Securities to the public without registration, USWS agrees to use its commercially reasonable efforts to:

(a)  Make and keep public information regarding USWS available, as those terms are understood and defined in Rule 144, at all times from and after the date hereof;

(b)  File with the Commission in a timely manner all reports and other documents required of USWS under the Securities Act and the Exchange Act at all times from and after the date hereof;

(c)  So long as a Holder, together with its Affiliates, owns any Registrable Securities, (i) unless otherwise available at no charge by access electronically to the Commission’s EDGAR filing system (or any successor system), furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of USWS, and such other reports and documents so filed as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing such Holder to sell any such securities without registration and (ii) to the extent accurate, furnish to such Holder upon reasonable request a written statement of USWS that it has complied with the reporting requirements of Rule 144; and

(d)  Provide opinion(s) of counsel as may be reasonably necessary in order for a Holder to avail itself of Rule 144 to allow such Holder to sell any Registrable Securities without registration, and remove, or cause to be removed, the notation of any restrictive legend on such Holder’s book-entry account maintained by USWS’s transfer agent, and bear all costs associated with the removal of such legend in USWS’s books.

Section 2.10 Transfer or Assignment of Registration Rights. The rights to cause USWS to register Registrable Securities granted to the Purchasers by USWS under this Article II may be transferred or assigned by each Purchaser to one or more transferee(s) or assignee(s) of such Registrable Securities or securities convertible, redeemable or exchangeable for Registrable Securities (including the Purchased Securities), in each case, who (a) (i) are Affiliates of such Purchaser, or (ii) hold, collectively with its or their Affiliates, after giving effect to such transfer or assignment, at least $10.0 million of Registrable Securities, and (b) who assume in writing responsibility for the obligations of such Purchaser under this Agreement with respect to the securities so transferred. USWS shall be given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned.

Section 2.11 Aggregation of Registrable Securities. All Registrable Securities held or acquired by Persons who are Affiliates of one another shall be aggregated together for the purpose of determining the availability of any rights under this Agreement. In addition, all other shares of Class A Common Stock held by a Person and for which such Person has similar registration rights pursuant to an agreement between such Person and USWS shall be aggregated together for the purpose of determining such Person’s rights under this Agreement solely as such shares relate to minimum quantity requirements contemplated herein; provided that, for the avoidance of doubt, such Class A Common Stock shall not otherwise be deemed Registrable Securities for any other purpose under this Agreement.

Section 2.12 Going Dark Period. Notwithstanding anything to the contrary in this Agreement, all rights and obligations under Section 2.1, Section 2.2 and Section 2.3 shall have no force and effect while USWS is not subject to Section 13 or 15(d) of the Exchange Act (“Going Dark Period”).

Section 2.13 IPO Registration.

(a)  IPO Registration Statement. At any time following a Going Dark Period, if USWS proposes to file a registration statement on Form S-1 or such other form under the Securities Act providing for the initial public offering of the Class A Common Stock (the “IPO Registration Statement”), USWS will notify in writing each Holder of the filing at least five (5) Business Days before the initial filing and afford each Holder an opportunity to include in the IPO Registration Statement all or any part of the Registrable Securities then held by such Holder; provided, however, that USWS shall not be required to include the Registrable Securities of the Holders in such Registration if the Holders do not offer a minimum of $5.0 million of Registrable Securities. Each Holder desiring to include in the IPO Registration Statement all or part of the Registrable Securities held by such Holder shall, within twenty (20) days after receipt of the above-described notice from USWS, so notify USWS in writing, and in such notice shall inform USWS of the number of Registrable Securities such Holder wishes to include in the IPO Registration Statement. Any election by any Holder to include any Registrable Securities in the IPO Registration Statement will not affect the inclusion of such Registrable Securities in the IPO Registration Statement until such Registrable Securities have been sold under the IPO Registration Statement.

(b)  Right to Terminate IPO Registration. USWS shall have the right to terminate or withdraw the IPO Registration Statement initiated by it and referred to in this Section 2.13(b) prior to the effectiveness of such Registration whether or not any Holder has elected to include Registrable Securities in such Registration; provided, however, USWS must provide each Holder that elected to include any Registrable Securities in such IPO Registration Statement prompt written notice of such termination or withdrawal. Furthermore, in the event the IPO Registration Statement is not declared effective within one hundred twenty (120) days following the initial filing of the IPO Registration Statement, unless a road show for the Underwritten Offering pursuant to the IPO Registration Statement is actually in progress at such time or such IPO Registration Statement has been terminated or withdrawn pursuant to this Section 2.13(b), USWS shall promptly provide a new written notice to all Holders giving them another opportunity to elect to include Registrable Securities in the pending IPO Registration Statement. Each Holder receiving such notice shall have the same election rights afforded such Holder as described above in this Section 2.13.

(c)  Priority of Piggyback Registration. If the Managing Underwriter or Underwriters advises USWS that the total shares of Class A Common Stock which the Selling Holders and any other Persons intend to include in the IPO Registration Statement exceeds the number which can be sold in such offering without being likely to have an adverse effect on the offering price, timing or probability of success of the distribution of the Class A Common Stock offered or the market for the Class A Common Stock, then USWS shall furnish notice in writing (including by e-mail) to the Holders that elected to include any Registrable Securities in such IPO Registration Statement, and the Class A Common Stock to be included in such IPO Registration Statement shall include the number of shares of Class A Common Stock that such Managing Underwriter or Underwriters advises USWS can be sold without having such adverse effect, with such number to be allocated (i) first, to USWS, (ii) second, pro rata among the Selling Holders and any Other Holders who have requested participation in the IPO Registration Statement (based, for each such Selling Holder or Other Holder, on the percentage derived by dividing (1) the number of shares of Class A Common Stock proposed to be sold by such Selling Holder or such Other Holder in such

offering; by (2) the aggregate number of shares of Class A Common Stock proposed to be sold by all Selling Holders and all Other Holders in the Piggyback Registration), and (iii) third, to any other holder of shares of Class A Common Stock with registration rights that are subordinate to the rights of the Holders hereunder.

Section 3.5 Specific Performance. Damages in the event of breach of this Agreement by a party hereto would be difficult, if not impossible, to ascertain, and it is therefore agreed that each such Person, in addition to and without limiting any other remedy or right it may have, will have the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any such breach, and enforcing specifically the terms and provisions hereof, and each of the parties hereto hereby waives (a) any and all defenses it may have on the ground of lack of jurisdiction or competence of the court to grant such an injunction or other equitable relief or that a remedy at law would be adequate and (b) any requirement under any law to post securities as a prerequisite to obtaining equitable relief. The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity which such Person may have.

Section 3.6 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.

Section 3.8 Governing Law, Submission to Jurisdiction. NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION. Each of the parties hereto irrevocably agrees that any legal action or proceeding with respect to this Agreement or the Transactions shall be brought and determined by courts of the State of New York located in the Borough of Manhattan, City of New York and the federal courts of the United States of America located in the State of New York, Southern District, and each of the parties hereto irrevocably submits to the exclusive jurisdiction of such courts solely in respect of any legal proceeding arising out of or related to this Agreement.

Section 3.9 Waiver of Jury Trial. THE PARTIES TO THIS AGREEMENT EACH HEREBY WAIVE, AND AGREE TO CAUSE THEIR AFFILIATES TO WAIVE, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (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. THE PARTIES TO THIS AGREEMENT EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

Section 3.10 Severability of Provisions. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof or affecting or impairing the validity or enforceability of such provision in any other jurisdiction.

Section 3.11 Entire Agreement. This Agreement and the Purchase Agreement 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 or therein. There are no restrictions, promises, warranties or undertakings, other than those set forth or referred to herein or therein with respect to the rights granted by USWS set forth herein or therein. This Agreement, the Purchase Agreement and the Confidentiality Agreement supersede all prior agreements and understandings between the parties with respect to such subject matter.

Section 3.12 Term; Amendment. This Agreement shall automatically terminate and be of no further force and effect on the date on which there are no Registrable Securities. This Agreement may be amended only by means of a written amendment signed by USWS and the Holders of a majority of the then outstanding Registrable Securities; provided, however, that no such amendment shall materially and adversely affect the rights of any Holder hereunder without the consent of such Holder.

Section 3.13 No Presumption. In the event any claim is made by a party relating to any conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel.

Section 3.14 Obligations Limited to Parties to Agreement. Each of the parties hereto covenants, agrees and acknowledges that no Person other than the Purchasers, Selling Holders, their respective permitted assignees and USWS shall have any obligation hereunder and that, notwithstanding that one or more of USWS and the Purchasers may be a corporation, partnership or limited liability company, no recourse under this Agreement or under any documents or instruments delivered in connection herewith or therewith shall be had against any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of USWS, the Purchasers, Selling Holders or their respective permitted assignees, or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise by incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of

any of USWS, the Purchasers, Selling Holders or any of their respective assignees, or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or Affiliate of any of the foregoing, as such, for any obligations of USWS, the Purchasers, Selling Holders or their respective permitted assignees under this Agreement or any documents or instruments delivered in connection herewith or therewith or for any claim based on, in respect of or by reason of such obligation or its creation, except in each case for any assignee of the Purchasers or a Selling Holder hereunder.

Section 3.15 Interpretation. Article and Section references in this Agreement are references to the corresponding Article and Section to this Agreement, unless otherwise specified. 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.” Whenever any determination, consent or approval is to be made or given by a Purchaser under this Agreement, such action shall be in such Purchaser’s sole discretion unless otherwise specified.

Section 3.16 No Inconsistent Agreements; Additional Rights.
