(h) To endeavor, in cooperation with the Underwriters, to qualify the Shares for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representatives may designate and to maintain such qualifications in effect so long as required to complete the distribution of the Shares; provided, however, that no Liberty Party shall be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

(i) To use its best efforts to maintain the listing of the Shares on the NYSE.

(j) For so long as the Company is subject to the reporting requirements of Section 13(g) or 15(d) of the Exchange Act, to maintain a transfer agent and, if necessary under the jurisdiction of formation of the Company, a registrar for the Class A Common Stock.

(k) To make generally available to the Company’s security holders and to you as soon as practicable an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

(l) The Company also covenants with each Underwriter that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period ending 30 days after the date of the Prospectus (the “Restricted Period”), (1) offer, pledge, 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 other securities convertible into or exercisable or exchangeable for Class A Common Stock (other than the grant or issuance of Class A Common Stock, other shares, options or other awards pursuant to employee benefit plans, qualified option plans or other employee compensation plans existing on the date hereof or described in the most recent preliminary prospectus), (2) file any registration statement with the Commission relating to the offering of any shares of Class A Common Stock or any securities convertible into or exercisable

19

or exchangeable for Class A Common Stock (other than any registration statement on Form S-8 or an amendment to any registration statement on Form S-8), (3) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Class A Common Stock, whether any such transaction described in clause (1), (2) or (3) above is to be settled by delivery of Class A Common Stock or such other securities, in cash or otherwise. In addition, each of the Liberty Parties agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for, or exercise any right with respect to, the registration of any shares of Class A Common Stock or any security convertible into or exercisable or exchangeable for Class A Common Stock.

The restrictions contained in the preceding paragraph shall not apply to (a) the issuance by the Company of shares of Class A Common Stock upon the exercise of an option or warrant or the exchange or conversion of a security outstanding on the date hereof of which the Underwriters have been advised in writing or which has been disclosed in the Registration Statement, Time of Sale Prospectus or Prospectus or (b) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Class A Common Stock, provided that (i) such plan does not provide for the transfer of Class A Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Class A Common Stock may be made under such plan during the Restricted Period.

The Company also covenants with each Underwriter that, without the prior written consent of the Underwriters, it will not, during the Restricted Period, waive the lockup and transfer restrictions set forth in Section 4.1(a) of the Amended and Restated Stockholders Agreement, dated December 31, 2020, by and among the Company and other parties thereto.

8. Covenants of the Selling Shareholders. Each Selling Shareholder, severally and not jointly, covenants with each Underwriter as follows:

(a) To deliver to each Underwriter (or its agent), prior to or at the Closing Date, a properly completed and executed Internal Revenue Service (“IRS”) Form W-9 or an IRS Form W-8, as appropriate, together with all required attachments to such form.

(b) During the offering period, not to take, directly or indirectly, any action designed to cause or result in, or which might reasonably be expected to constitute, the stabilization or manipulation of the price of the Class A Common Stock to facilitate the sale or resale of the Class A Common Stock in violation of any law, rule or regulation.

(c) To advise the Underwriters promptly, and if requested by the Underwriters, to confirm such advice in writing, so long as delivery of a prospectus relating to the Shares by an underwriter or dealer may be required under the Securities Act, of any material change in such Selling Shareholder’s Selling Shareholder Information which comes to the attention of such Selling Shareholder.

(d) To deliver to each Underwriter (or its agent) a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation and to undertake to provide such additional supporting documentation, in each case as each Underwriter may reasonably request in connection with the verification of the foregoing certification.

9. Expenses. Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Liberty Parties agree to pay or cause to be paid all expenses incident to the performance of their obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Liberty Parties’ counsel and of the counsel for the Selling Shareholders and the Company’s accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by any of the Liberty Parties and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies

20

thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 7(h) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Shares by FINRA (including related fees and expenses of counsel to the Underwriters), (v) the cost of printing certificates representing the Shares, (vi) the costs and charges of any transfer agent, registrar or depositary, (vii) the costs and expenses of the Liberty Parties relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants and 50% of the cost of any aircraft chartered in connection with the road show, (viii) the document production charges and expenses associated with printing this Agreement and (ix) all other costs and expenses incident to the performance of the obligations of the Liberty Parties and the Selling Shareholders hereunder for which provision is not otherwise made in this Section 9. It is understood, however, that except as provided in this Section 9, Section 11 entitled “Indemnity and Contribution,” and the last paragraph of Section 13 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make.

The provisions of this Section 9 shall not supersede or otherwise affect any agreement that the Liberty Parties and the Selling Shareholders may otherwise have for the allocation of such expenses among themselves.

10. Covenants of the Underwriters. Each Underwriter severally covenants with the Liberty Parties not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

11. Indemnity and Contribution. (a) The Liberty Parties, jointly and severally, agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each selling agent and affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein.

(b) The Selling Shareholders, severally and not jointly, agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration

21

Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show, or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, but such indemnification shall apply only to losses, claims, damages or liabilities caused by information relating to such Selling Shareholder furnished to the Company or the Underwriters in writing by or on behalf of such Selling Shareholder expressly for use therein, it being understood and agreed upon that the only such information furnished by such Selling Shareholder consists only of such Selling Shareholder’s Selling Shareholder Information. Notwithstanding anything to the contrary in this Section 11, the liability of any Selling Shareholder under this Section 11 shall be limited to an amount equal to the aggregate Purchase Price of the Shares, if any, sold by such Selling Shareholder under this Agreement.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Liberty Parties, the Selling Shareholders, the Company’s directors, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company or any of the Selling Shareholders within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show or the Prospectus or any amendment or supplement thereto.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 11(a), 11(b) or 11(c), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Selling Shareholders and all persons, if any, who control the Selling Shareholders within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. In the case of any such separate firm for the Selling Shareholders and such control persons of the Selling Shareholders, such firm shall be designated in writing by the persons named as attorneys-in-fact for the Selling Shareholders under the Powers of Attorney. The indemnifying party shall not be liable for any settlement of any

22

proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any such indemnified party.

(e) To the extent the indemnification provided for in Section 11(a), 11(b) or 11(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (e)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (e)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Selling Shareholders on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Selling Shareholders, which obligations shall be several and not joint under this Section 11(e), and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company and the Selling Shareholder on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Shareholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 11 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(f) The Company, the Selling Shareholders and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 11 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 11(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 11(e) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 11, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 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 was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 11 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

23

(g) The indemnity and contribution provisions contained in this Section 11 and the representations, warranties and other statements of the Company and the Selling Shareholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, the Selling Shareholders or any person controlling a Selling Shareholder, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

12. Termination. The Underwriters may terminate this Agreement at any time by notice given by you to the Company and the Selling Shareholders, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the NYSE, the NYSE MKT, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or other relevant exchanges, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and which, individually or together with any other event specified in this clause (v), makes it, in your judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Registration Statement, the Time of Sale Prospectus or the Prospectus.

13. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 13 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Shares and the aggregate number of Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Shares to be purchased on such date, and arrangements satisfactory to you and the Selling Shareholders for the purchase of such Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Selling Shareholders. In any such case either you or the Selling Shareholders shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Selling Shareholders to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Selling Shareholders shall be unable to perform their obligations under this Agreement, the Selling Shareholders will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

24

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Liberty Parties will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

14. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement among the Company and the Selling Shareholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Company and each Selling Shareholder acknowledges that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company, the Selling Shareholders or any other person, (ii) the Underwriters owe the Company and the Selling Shareholders only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Selling Shareholders. The Company and each Selling Shareholder waives to the fullest extent permitted by applicable law any claims they may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

(c) Each Selling Shareholder further acknowledges and agrees that, although the Underwriters may provide certain Selling Shareholders with certain Regulation Best Interest and Form CRS disclosures or other related documentation in connection with the offering, the Underwriters are not making a recommendation to any Selling Shareholder to participate in the offering or sell any Shares at the Purchase Price, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

15. Information Furnished by the Underwriters. The Company and the Selling Shareholders acknowledge that the following statements set forth in the most recent preliminary prospectus and the Prospectus: (a) the names of the Underwriters, (b) the statements set forth in the last paragraph on the cover page of the Prospectus, (c) the information contained in paragraph 10 under the caption “Underwriting” and (d) the information contained in paragraphs 12, 13 and 14 under the caption “Underwriting” constitute the only information furnished by or on behalf of the Underwriters for inclusion in any preliminary prospectus, the Registration Statement, the Prospectus, any issuer free writing prospectus or in any amendment or supplement thereto.

16. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

The use of electronic signatures and electronic records (including, without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law, including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

17. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

18. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

LLC, 1585 Broadway, New York, New York 10036, Attention: Equity Syndicate Desk, with a copy to the Legal Department; if to the Selling Shareholders shall be delivered, mailed or sent to 712 Fifth Avenue, 19th Floor, New York, New York 10019; and if to the Liberty Parties shall be delivered, mailed or sent to Liberty Oilfield Services Inc., 950 17^th Street, Suite 2400, Denver Colorado 80202, Attention: Sean Elliott, Vice President and General Counsel.

20. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

10. The Registration Statement became effective under the Securities Act on July 8, 2019; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time period required by such rule.

11. The statements made in or incorporated by reference into the Registration Statement, the Time of Sale Prospectus and the Prospectus under the heading “Description of Capital Stock” and in the Registration Statement in Item 14, to the extent that they constitute descriptions or summaries of the terms of the Class A Common Stock or the documents referred to therein, or refer to statements of federal law, the laws of the State of Delaware or legal conclusions, are accurate in all material respects.

The Registration Statement, as of its latest effective date, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) and at the Closing Date (in each case other than (i) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon, (ii) the other financial data derived therefrom and (iii) other financial data, in each case included in or omitted from the Registration Statement and the Prospectus, as to which we express no opinion), each appeared on its face to comply as to form in all material respects with the requirements of the Securities Act.

We have participated in conferences with representatives of the Company and with representatives of its independent accountants and counsel for the Underwriters, at which conferences the contents of the Registration Statement, the Time of Sale Prospectus and the Prospectus and any amendment and supplement thereto and related matters were discussed. Although we have not undertaken to determine independently, and do not assume any responsibility for, or express opinion regarding (other than listed in paragraph 11 above), the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus, based upon the participation described above (relying as to factual matters upon statements of fact made to us by representatives of the Company), nothing has come to our attention to cause us to believe that:

A-1-2

(a) the Registration Statement, as of its latest effective date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

(b) the Time of Sale Prospectus, as of the Time of Sale, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or

EXHIBIT A-2

Form of Willkie Farr & Gallagher LLP Opinion

1. Each Selling Shareholder has limited partnership power and authority to sell the Shares to be sold by it and to execute, deliver and perform its obligations under the Underwriting Agreement. All limited partnership action required to be taken by such Selling Shareholder for the sale and delivery of the Shares, and the execution and delivery by such Selling Shareholder of the Underwriting Agreement has been validly taken to the extent required to be taken as of the date hereof.

2. The Underwriting Agreement has been duly authorized, executed and delivered by or on behalf of each Selling Shareholder.

3. The execution and delivery by the Selling Shareholders of, and the performance by the Selling Shareholders of their obligations under, the Underwriting Agreement, and the sale of the Shares pursuant to the Underwriting Agreement will not contravene any provision of applicable law that in our experience normally would be applicable to transactions of the type contemplated by the Underwriting Agreement, or the Organizational Documents of the Selling Shareholders, except as would not reasonably be expected to have a material adverse effect on the ability of the Selling Shareholders to perform their obligations under the Underwriting Agreement, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Selling Shareholders of their obligations under the Underwriting Agreement, except such as may be required by the securities laws of the various states in connection with offer and sale of the Shares.

4. Upon payment for the Shares to be sold by the Selling Shareholders pursuant to the Underwriting Agreement, delivery (within the meaning of Section 8-301(b) of the UCC) of such Shares, as directed by the Underwriters, to Cede or such other nominee as may be designated by DTC, registration of such Shares in the name of Cede or such other nominee and the crediting of such Shares on the books of DTC to the securities account (as defined in Section 8-501(a) of the UCC) at DTC of each applicable Underwriter (assuming that no Underwriter has notice of any adverse claim within the meaning of Section 8-105 of the UCC to such Shares to which the security entitlement relates or to the Selling Shareholders’ security entitlement), (a) under Section 8-501(b)(1) of the UCC, the Underwriters will acquire a valid security entitlement (as defined in Section 8-102(a)(17) of the UCC) in respect of such Shares and (b) no action based on any “adverse claim” (as defined in Section 8-102(a)(1) of the UCC) to such Shares may be asserted against the Underwriters with respect to such security entitlement, assuming, in each case, that when such payment, delivery and crediting occur, (i) such Shares will have been registered in the name of Cede or another nominee designated by DTC, in each case on the Company’s share registry in accordance with the Company Organizational Documents (as defined in the Underwriting Agreement) and applicable law, (ii) DTC will be registered as a “clearing corporation” as defined in Section 8-102(a)(5) of the UCC and (iii) appropriate entries to the securities accounts of the applicable Underwriters on the records of DTC will have been made pursuant to the UCC.

The foregoing opinions are subject to the following assumptions, qualifications and exceptions:

1. In connection with the opinions set forth in paragraph 3 above, we have not made any independent investigation of any domestic or foreign court, governmental or regulatory records to determine: (a) if there are any judgments, orders or decrees of any domestic or foreign court or governmental body, agency or authority having jurisdiction over the Selling Shareholders or their assets; (b) if there exists any judgment, order, injunction or other restraint issued or filed with respect to the transactions contemplated by the Underwriting Agreement or the performance by the Selling Shareholders of their obligations thereunder; or (c) if any action, suit, claim or proceeding has been filed or is pending to which any Selling Shareholder is a party.

2. We are members of the bar of the State of New York, and the opinions set forth in paragraph 4 above are (a) limited to the effect of Article 8 of the UCC, and (b) expressed as if Article 8 of the UCC applies to the opinions.

A-2-1

3. In connection with our opinions set forth in paragraph 4 above, we have assumed that (a) DTC is a “clearing corporation” as defined in Section 8-102(a)(5) of the UCC and a “securities intermediary” as defined in Section 8-102(a)(14) of the UCC, and the State of New York is the “securities intermediary’s jurisdiction” of DTC for purposes of Section 8-110 of the UCC, (b) DTC indicates by book entries that the Shares have been credited to the applicable Underwriters’ securities accounts and such Shares have been credited to the applicable Underwriters’ security accounts at DTC and (c) DTC has not adopted any rules that conflict with Article 8 of the UCC. We call to your attention that pursuant to Section 8-511(b) and 8-511(c) of the UCC, claims of creditors of any securities intermediary or clearing corporation may be given priority to the extent set forth therein. In addition, if at any time DTC does not have sufficient securities to satisfy claims of all of its entitlement holders with respect thereto, then all holders will share pro rata in the securities then held by DTC.

4. The opinions set forth in paragraph 4 above are subject to (a) applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally and (b) general principles of equity whether considered in a proceeding at law or in equity (including the possible unavailability of specific performance or injunctive relief), commercial reasonableness, conscionability, good faith and fair dealing and the discretion of a court before which a proceeding is brought.

5. The opinions expressed herein are limited to laws, statutes, orders, rules or regulations typically applicable to transactions such as the offering of the Shares contemplated by the Underwriting Agreement.

We express no opinion as to the laws of any jurisdiction other than the laws of the State of New York, the Delaware Revised Uniform Limited Partnership Act and the federal securities laws of the United States as in effect on the date of this opinion.
