FORM OF SUBSCRIPTION AGREEMENT

Exhibit 10.1

This SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into on February 21, 2021, by and between NextGen Acquisition Corporation, a Cayman Islands exempted company (“NextGen”), and the undersigned subscriber (the “Investor”).

WHEREAS, this Subscription Agreement is being entered into in connection with the Agreement and Plan of Merger, dated as of the date hereof (as may be amended, supplemented or otherwise modified from time to time, the “Transaction Agreement”), by and among NextGen, Xos, Inc., a Delaware corporation (the “Company”), Sky Merger Sub I, Inc., a Delaware corporation (“NextGen Merger Sub”), and the other parties thereto, pursuant to which, among other things, NextGen Merger Sub will merge with and into the Company, with the Company as the surviving company in the merger and, after giving effect to such merger, becoming a wholly owned subsidiary of NextGen, and NextGen will change its name to “Xos, Inc.”, on the terms and subject to the conditions therein (the “Transaction”);

WHEREAS, prior to the closing of the Transaction (and as more fully described in the Transaction Agreement), NextGen will domesticate as a Delaware corporation in accordance with Section 388 of the General Corporation Law of the State of Delaware and Part XII of the Cayman Islands Companies Law (2020 Revision) (the “Domestication”);

WHEREAS, in connection with the Transaction, NextGen is seeking commitments from interested investors to purchase, following the Domestication and prior to the closing of the Transaction, shares of NextGen’s Class A common stock, par value $0.0001 per share, as such shares will exist as common stock following the Domestication (the “Shares”), in a private placement for a purchase price of $10.00 per share (the “Per Share Subscription Price”);

WHEREAS, the aggregate purchase price to be paid by the Investor for the subscribed Shares (as set forth on the signature page hereto) is referred to herein as the “Subscription Amount;”

WHEREAS, substantially concurrently with the execution of this Subscription Agreement, NextGen is entering into: (a) separate subscription agreements with certain other investors that may include existing directors, officers or securityholders (including, for the avoidance of doubt, holders of convertible securities) of NextGen, NextGen Sponsor LLC, a Cayman Islands limited liability company, the Company and/or their respective affiliates with an aggregate purchase price of $500,000 (collectively, the “Insider PIPE Investors” and, such investment, the “Insider PIPE Investment”) substantially similar to this Subscription Agreement; and (b) separate subscription agreements (collectively, the “Other Subscription Agreements”) substantially similar to this Subscription Agreement with certain investors (other than the Insider PIPE Investors) with an aggregate purchase price of $219,500,000 (inclusive of the Subscription Amount) (together with the Insider PIPE Investment, the “PIPE Investment”).

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, set forth herein, and intending to be legally bound hereby, each of the Investor and NextGen acknowledges and agrees as follows:

1. Subscription. Subject to the terms and conditions hereof, the Investor hereby subscribes for and agrees to purchase from NextGen the number of Shares set forth on the signature page of this Subscription Agreement on the terms and subject to the conditions provided for herein. The Investor acknowledges and agrees that, as a result of the Domestication, the Shares that will be issued pursuant hereto shall be shares of common stock in a Delaware corporation (and not shares in a Cayman Islands exempted company).

2. Closing. The closing of the sale of the Shares contemplated hereby (the “Closing”) shall occur on the closing date of the Transaction (the “Closing Date”) and be conditioned upon the prior or substantially concurrent consummation of the Transaction and satisfaction of the other conditions set forth in Section 3 hereof. Upon delivery of written notice from (or on behalf of) NextGen to the Investor (the “Closing Notice”), that NextGen reasonably expects all conditions to the closing of the Transaction to be satisfied or waived on an expected closing date that is not less than five (5) business days from the date on which the Closing Notice is delivered to the Investor, the Investor shall deliver to NextGen, one (1) business day prior to the expected closing date specified in the Closing Notice (or such other date agreed to in writing by NextGen), the Subscription Amount by wire transfer of United States dollars in immediately available funds to the account(s) specified by NextGen in the Closing Notice. On the Closing Date, NextGen shall issue the Shares to the Investor and subsequently cause the Shares to be registered in book-entry form in the name of the Investor on NextGen’s share register. For purposes of this Subscription Agreement, “business day” shall mean a day, other than a Saturday, Sunday or other day on which commercial banks in New York, New York or governmental authorities in the Cayman Islands (for so long as NextGen remains domiciled in Cayman Islands) are authorized or required by law to close. Prior to or at the Closing Date, Investor shall deliver to NextGen a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. In the event the Closing Date does not occur within two (2) business days after the expected closing date specified in the Closing Notice, NextGen shall promptly (but not later than two (2) business days after the expected closing date specified in the Closing Notice) return the Subscription Amount to the Investor by wire transfer of U.S. dollars in immediately available funds to the account specified by the Investor, and any book-entries for the Shares shall be deemed cancelled; provided that, unless this Subscription Agreement has been terminated pursuant to Section 8 hereof, such return of funds shall not terminate this Subscription Agreement or relieve the Investor of its obligation to purchase the Shares at the Closing. For the avoidance of doubt, if any termination hereof occurs after the delivery by the Investor of the Subscription Amount for the Shares and prior to the Closing, NextGen shall promptly (but not later than three (3) business days thereafter) return the Purchase Price to Investor without any deduction for or on account of any tax, withholding, charges or set-off.

3. Closing Conditions. The obligation of the parties hereto to consummate the purchase and sale of the Shares pursuant to this Subscription Agreement is subject to the satisfaction of the following conditions:

(a) there shall not be in force any injunction or order enjoining or prohibiting the issuance and sale of the Shares under this Subscription Agreement;

(b) solely with respect to the Investor’s obligation to close, the terms of the Transaction Agreement (including any minimum cash condition and the other conditions thereto) shall not have been amended or waived in a manner that would reasonably be expected to materially and adversely affect the Investor, without the consent of the Investor;

(c) all conditions precedent to the closing of the Transaction as set forth in the Transaction Agreement, including all necessary approvals of NextGen’s shareholders and regulatory approvals, if any, shall have been satisfied or waived (as determined by the parties to the Transaction Agreement and other than those conditions that, by their nature, (x) may only be satisfied at the closing of the Transaction (including to the extent that any such condition is dependent upon the consummation of the purchase and sale of the Shares pursuant to this Subscription Agreement and the Other Subscription Agreements), but subject to the satisfaction or waiver of such conditions as of the Closing, or (y) will be satisfied by the Closing and the closing of the transactions contemplated by the Other Subscription Agreements);

(d) (i) solely with respect to the Investor’s obligation to close, the representations and warranties made by NextGen, and (ii) solely with respect to NextGen’s obligation to close, the representations and warranties made by the Investor, in each case, in this Subscription Agreement shall be true and correct in all material respects as of the Closing Date other than (x) those representations and warranties qualified by materiality, Material Adverse Effect or similar qualification, which shall be true and correct in all respects as of the Closing Date and (y) those representations and warranties expressly made as of an earlier date, which shall be true and correct in all material respects (or, if qualified by materiality, Material Adverse Effect or similar qualification, all respects) as of such date, in each case without giving effect to the consummation of the Transactions;

(e) solely with respect to NextGen’s obligation to close, the Investor shall have wired the Subscription Amount in accordance with Section 2 of this Subscription Agreement and otherwise performed or complied in all material respects all of its covenants and agreements contained in this Subscription Agreement that are required to be performed or complied with by the Investor on or before the Closing Date;

(a) NextGen is an exempted company duly incorporated, validly existing and in good standing under the laws of the Cayman Islands. NextGen has all power (corporate or otherwise) and authority to own, lease and operate its properties and conduct its business as presently conducted and to enter into, deliver and perform its obligations under this Subscription Agreement. As of the Closing Date, following the Domestication, NextGen will be duly incorporated, validly existing as a corporation and in good standing under the laws of the State of Delaware.

(c) This Subscription Agreement has been duly authorized, executed and delivered by NextGen and, assuming that this Subscription Agreement constitutes the valid and binding agreement of the Investor, this Subscription Agreement constitutes a valid and binding agreement of NextGen and is enforceable against NextGen in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally, or (ii) principles of equity, whether considered at law or equity.

(d) The issuance and sale by NextGen of the Shares and the compliance by NextGen with all of the provisions pursuant to this Subscription Agreement and the consummation of the transactions contemplated hereby will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of NextGen or any of its subsidiaries pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which NextGen or any of its subsidiaries is a party or by which NextGen or any of its subsidiaries is bound or to which any of the property or assets of NextGen is subject that would reasonably be expected to have a material adverse effect on the business, financial condition or results of operations of NextGen and its subsidiaries, taken as a whole (a “Material Adverse Effect”), or materially affect the validity of the Shares or the legal authority of NextGen to comply in all material respects with its obligations under this Subscription Agreement; (ii) result in any violation of the provisions of the organizational documents of NextGen; or (iii) result in any violation of any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over NextGen or any of its properties that would reasonably be expected to have a Material Adverse Effect or materially affect the validity of the Shares or the legal authority of NextGen to comply in all material respects with its obligations under this Subscription Agreement.

(e) As of their respective filing dates, all reports required to be filed by NextGen with the U.S. Securities and Exchange Commission (the “SEC”) since October 9, 2020 (the “SEC Reports”) complied in all material respects with the applicable requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder and none of the SEC Reports, when filed, contained any untrue statement of material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of NextGen included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of NextGen as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments. As of the date hereof, there are no material outstanding or unresolved comments in comment letters received by NextGen from the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports.

(f) Assuming the accuracy of the Investor’s representations and warranties set forth in Section 6 of this Subscription Agreement, NextGen is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization or other person in connection with the issuance of the Shares pursuant to this Subscription Agreement, other than (i) filings with the SEC, (ii) filings required by applicable state securities laws, (iii) the filings required in accordance with Section 12 of this Subscription Agreement; (iv) those required by the NYSE or Nasdaq, including with respect to obtaining approval of NextGen’s stockholders, and (v) the failure of which to obtain would not be reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or have a material adverse effect on NextGen’s ability to consummate the transactions contemplated hereby, including the sale and issuance of the Shares.

(g) As of the date hereof, NextGen has not received any written communication from a governmental authority that alleges that NextGen is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(h) As of the date hereof, there is no (i) suit, action, claim, proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of NextGen, threatened against NextGen or (ii) judgment, decree, injunction, ruling or order of any governmental entity or arbitrator outstanding against NextGen, except, in each case, for such matters as would not be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect.

(i) Assuming the accuracy of the Investor’s representations and warranties set forth in Section 6 of this Subscription Agreement, no registration under the Securities Act of 1933, as amended (the “Securities Act”), is required for the offer and sale of the Shares by NextGen to the Investor.

(j) Neither NextGen nor any person acting on its behalf has offered or sold the Shares by any form of general solicitation or general advertising in violation of the Securities Act.

(k) As of the date hereof, the authorized share capital of NextGen consists of (i) 5,000,000 undesignated preferred shares, par value $0.0001 per share (“Preferred Shares”), (ii) 500,000,000 Class A Shares and (iii) 50,000,000 Class B ordinary shares, par value $0.0001 per share (“Class B Shares”). As of the date hereof: (1) no Preferred Shares are issued and outstanding, (2) 35,000,000 Class A Shares are issued and outstanding, (3) 8,750,000 Class B Shares are issued and outstanding and (4) 17,666,667 warrants, each entitling the holder thereof to purchase one Class A Share at an exercise price of $11.50 per Class A Share, are outstanding.

(l) As of the date hereof, the issued and outstanding Class A Shares are registered pursuant to Section 12(b) of the Exchange Act and are listed for trading on Nasdaq. There is no suit, action, proceeding or investigation pending or, to the knowledge of NextGen, threatened against NextGen by Nasdaq or the SEC with respect to any intention by such entity to deregister NextGen’s Class A Shares or prohibit or terminate the listing of NextGen’s Class A Shares on Nasdaq. NextGen has taken no action that is designed to terminate the registration of its Class A Shares under the Exchange Act. Following the Domestication, the Shares are expected to be registered for resale under the Securities Act.

(m) Other than as set forth in the Transaction Agreement, there are no securities or instruments issued by or to which NextGen is a party containing anti-dilution or similar provisions that will be triggered by the issuance of (i) the Shares or (ii) the shares to be issued pursuant to any Other Subscription Agreement that have not been or will not be validly waived on or prior to the Closing Date.

(n) NextGen is not under any obligation to pay any broker’s fee or commission in connection with the sale of the Shares other than to the Placement Agent (as defined below).

(o) The Other Subscription Agreements reflect the same Per Share Subscription Price and other terms and conditions with respect to the purchase of the Shares that are no more favorable to such subscriber thereunder than the terms of this Subscription Agreement, other than terms particular to the regulatory requirements of such subscriber or its affiliates or related funds, and there is no side letter or other agreement that modifies such Per Share Subscription Price and such other terms and conditions with respect to the purchase of the Shares. For the avoidance of doubt, this

Section 5(o) shall not apply to any document entered into in connection with the Insider PIPE Investment; provided, however, that such Insider PIPE Investment shall be with respect to the same class of Shares being acquired by the Investor hereunder and at the same Per Share Subscription Price.

(a) NextGen agrees that, within fifteen (15) business days following the Closing Date (such deadline, the “Filing Deadline”), NextGen will submit to or file with the SEC (at NextGen’s expense) a registration statement for a shelf registration on Form S-1, Form S-3 (if NextGen is then eligible to use a Form S-3 shelf registration) or other appropriate form (the “Registration Statement”), in each case, covering the resale of the Shares acquired by the Investor pursuant to this Agreement which are eligible for registration (determined as of two (2) business days prior to such submission or filing) (the “Registrable Shares”) and NextGen shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 60^th calendar day following the filing date thereof if the SEC notifies NextGen that it will “review” the Registration Statement and (ii) the 5^th business day after the date NextGen is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effectiveness Deadline”); provided, however, that NextGen’s obligations to include the Registrable Shares in the Registration Statement are contingent upon Investor furnishing in writing to NextGen such information regarding Investor or its permitted assigns, the securities of NextGen held by Investor and the intended method of disposition of the Registrable Shares (which shall be limited to non-underwritten public offerings) as shall be reasonably requested by NextGen to effect the registration of the Registrable Shares, and Investor shall execute such documents in connection with such registration as NextGen may reasonably request that are customary of a selling stockholder in similar situations, including providing that NextGen shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement, if applicable, during any customary blackout or similar period or as permitted hereunder; provided that Investor shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Registrable Shares. NextGen will use its commercially reasonable efforts to provide a draft of the Registration Statement to Investor for review at least two (2) business days in advance of the date of filing the Registration Statement with the SEC; provided that for the avoidance of doubt, in no event shall NextGen be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Investor’s review. For as long as the Investor holds Shares, NextGen will use commercially reasonable efforts to file all reports for so long as the condition in Rule 144(c)(1) (or Rule 144(i)(2), if applicable) is required to be satisfied, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Shares pursuant to Rule 144 of the Securities Act (in each case, when Rule 144 of the Securities Act becomes available to the Investor). Any failure by NextGen to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise relieve NextGen of its obligations to file or effect the Registration Statement as set forth above in this Section 7. Notwithstanding the foregoing, if the SEC prevents NextGen from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the SEC. In such event, the number of Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Registrable Shares under Rule 415 under the Securities Act, NextGen shall amend the Registration Statement or file a new Registration Statement to register such Registrable Shares not included in the initial Registration Statement and cause such amendment or Registration Statement to become effective as promptly as practicable. As soon as is reasonably practicable upon notification by the SEC that the Registration Statement has been declared effective by the SEC, NextGen shall file the final prospectus under Rule 424 of the Securities Act. In no event shall the Investor be identified as a statutory underwriter in the Registration Statement unless requested by the SEC; provided that if the SEC requests that the Investor be identified as a statutory underwriter in the Registration Statement, the Investor will have an opportunity to withdraw from the Registration Statement.

(b) At its expense NextGen shall:

(i) except for such times as NextGen is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which NextGen determines to obtain, continuously effective with respect to Investor, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (A) Investor ceases to hold any Registrable Shares, (B) the date all Registrable Shares held by Investor may be sold without restriction under Rule 144 promulgated under the Securities Act (“Rule 144”), including, without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144, and (C) three (3) years from the date of effectiveness of the Registration Statement;

(ii) advise Investor within five (5) business days:

(1) when a Registration Statement or any amendment thereto has been filed with the SEC and when such Registration Statement or any post-effective amendment thereto has become effective;

(2) after it shall receive notice or obtain knowledge thereof, of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(3) of the receipt by NextGen of any notification with respect to the suspension of the qualification of the Registrable Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(4) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, NextGen shall not, when so advising Investor of such events, provide Investor with any material, nonpublic information regarding NextGen other than to the extent that providing notice to Investor of the occurrence of the events listed in (1) through (4) above constitutes material, nonpublic information regarding NextGen;

(iii) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv) upon the occurrence of any event contemplated in Section 7(b)(ii)(4) above, except for such times as NextGen is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, NextGen shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(v) use its commercially reasonable efforts to cause all Registrable Shares to be listed on each securities exchange or market, if any, on which the shares of Class A common stock issued by NextGen have been listed;

(vi) cause NextGen’s transfer agent to remove the legend set forth above in Section 6(b)(i), at the Investor’s request, as soon as reasonably practicable after the Shares are sold pursuant to Rule 144 or the Registration Statement; and

(vii) otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investor, consistent with the terms of this Agreement, in connection with the registration of the Registrable Shares.

(c) Notwithstanding anything to the contrary in this Subscription Agreement, NextGen shall be entitled to delay the filing or effectiveness of, or suspend the use of, the Registration Statement if it determines, upon the advice of external legal counsel, that in order for the Registration Statement not to contain a material misstatement or omission, (i) an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, (ii) the negotiation or consummation of a transaction by NextGen or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event NextGen’s board of directors reasonably believes would require additional disclosure by NextGen in the Registration Statement of material information that NextGen has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of NextGen’s board of directors to cause the Registration Statement to fail to comply with applicable disclosure requirements, or (iii) in the good faith judgment of the majority of NextGen’s board of directors, such filing or effectiveness or use of such Registration Statement, would be seriously detrimental to NextGen and the majority of the NextGen board of directors concludes as a result that it is essential to defer such filing (each such circumstance, a “Suspension Event”); provided, however, that NextGen may not delay or suspend the Registration Statement on more than two (2) occasions or for more than sixty (60) consecutive calendar days, or more than ninety (90) total calendar days in each case during any twelve (12) month period. Upon receipt of any written notice from NextGen of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any 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 (in light of the circumstances under which they were made, in the case of the prospectus) not misleading, Investor agrees that (i) it will immediately discontinue offers and sales of the Registrable Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Investor receives copies of a supplemental or amended prospectus (which NextGen agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by NextGen that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by NextGen unless otherwise required by law or subpoena. If so directed by NextGen, Investor will deliver to NextGen or, in Investor’s sole discretion destroy, all copies of the prospectus covering the Registrable Shares in Investor’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Shares shall not apply (A) to the extent Investor is required to retain a copy of such prospectus (1) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (2) in accordance with a bona fide pre-existing document retention policy or (B) to copies stored electronically on archival servers as a result of automatic data back-up.

(d) The Investor may deliver written notice (an “Opt-Out Notice”) to NextGen requesting that the Investor not receive notices from NextGen otherwise required by Section 7; provided, however, that the Investor may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from the Investor (unless subsequently revoked), (i) NextGen shall not deliver any such notices to the Investor and the Investor shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to the Investor’s intended use of an effective Registration Statement, the Investor will notify NextGen in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 7(d)) and the related suspension period remains in effect, NextGen will so notify the Investor, within one (1) business day of the Investor’s notification to NextGen, by delivering to the Investor a copy of such previous notice of Suspension Event, and thereafter will provide the Investor with the related notice of the conclusion of such Suspension Event immediately upon its availability.

(e) Indemnification.

(i) NextGen agrees to indemnify, to the extent permitted by law, Investor (to the extent a seller under the Registration Statement), its directors, officers, partners, managers, members, investment advisors, employees, stockholders, agents and each person who controls Investor (within the meaning of the Securities Act), to the extent permitted by law, against all losses, claims, damages, liabilities and reasonable and documented out of pocket expenses (including, without limitation, reasonable and documented attorneys’ fees of one law firm and one local counsel in each applicable jurisdiction) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement (“Prospectus”) or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to NextGen by or on behalf of such Investor expressly for use therein or such Investor has omitted a material fact from such information or otherwise violated the Securities Act, Exchange Act or any state securities law or any other law, rule or regulation thereunder; provided, however, that the indemnification contained in this Section 7(e)(i) shall not apply to amounts paid in settlement of any losses, claims, damages, liabilities and out of pocket expenses if such settlement is effected without the consent of NextGen (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall NextGen be liable for any losses, claims, damages, liabilities and out of pocket expenses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information furnished by an Investor expressly for use in the Prospectus, (B) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by NextGen in a timely manner, (C) as a result of offers or sales effected by or on behalf of any person by means of a “free writing prospectus” (as defined in Rule 405 under the Securities Act) that was not authorized in writing by NextGen, or (D) in connection with any offers or sales effected by or on behalf of an Investor in violation of Section 7(c) hereof.

(ii) In connection with any Registration Statement in which an Investor is participating, such Investor shall furnish (or cause to be furnished) to NextGen in writing such information and affidavits as NextGen reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify NextGen, its directors, officers, agents, employees and each person or entity who controls NextGen (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and reasonable and documented out of pocket expenses (including, without limitation, reasonable and documented attorneys’ fees of one law firm) resulting from any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement or omission is contained (or not contained in, in the case of an omission) in any information or affidavit so furnished in writing by on behalf of such Investor expressly for use therein; provided, however, that the liability of such Investor shall be several and not joint with any other investor and shall be in proportion to and limited to the net proceeds received by such Investor from the sale of Registrable Shares giving rise to such indemnification obligation.

(iii) Any person or entity entitled to indemnification herein shall (A) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (B) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(iv) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of securities.

(v) If the indemnification provided under this Section 7(e) from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however, that the liability of the Investor shall be limited to the net proceeds received by such Investor from the sale of Registrable Shares giving rise to such indemnification obligation. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 7(d)(i), (ii) and (iii) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 7(d)(v) from any person or entity who was not guilty of such fraudulent misrepresentation.

8. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) if the conditions to Closing set forth in Section 3 of this Subscription Agreement are not satisfied, or are not capable of being satisfied, on or prior to the Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement will not be or are not consummated at the Closing and (d) August 21, 2021; provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover reasonable and documented out-of-pocket losses, liabilities or damages arising from any such willful breach. NextGen shall notify the Investor of the termination of the Transaction Agreement promptly after the termination of such agreement. Upon the termination of this Subscription Agreement in accordance with this Section 8, any monies paid by the Investor to NextGen in connection herewith shall be promptly (and in any event within one (1) business day after such termination) returned to the Investor.

9. Trust Account Waiver. The Investor acknowledges that NextGen is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving NextGen and one or more businesses or assets. The Investor further acknowledges that, as described in NextGen’s prospectus relating to its initial public offering dated October 6, 2020 (the “IPO Prospectus”) available at xxx.xxx.xxx, substantially all of NextGen’s assets consist of the cash proceeds of NextGen’s initial public offering and private placement of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of NextGen, its public shareholders and the underwriter of NextGen’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to NextGen to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the IPO Prospectus. For and in consideration of NextGen entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, the Investor hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account, and agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement; provided that nothing in this Section 9 shall (x) serve to limit or prohibit the Investor’s right to pursue a claim against NextGen for legal relief against assets held outside the Trust Account (so long as such claim would not affect NextGen’s ability to fulfill its obligation to effectuate any redemption right with respect to any securities of NextGen), for specific performance or other equitable relief, (y) serve to limit or prohibit any claims that the Investor may have in the future against NextGen’s assets or funds that are not held in the Trust Account (including any funds that have been released from the Trust Account and any assets that have been purchased or acquired with any such funds) (so long as such claim would not affect NextGen’s ability to fulfill its obligation to effectuate any redemption right with respect to any securities of NextGen) or (z) be deemed to limit the Investor’s right, title, interest or claim to the Trust Account by virtue of the Investor’s record or beneficial ownership of Shares of NextGen acquired by any means other than pursuant to this Subscription Agreement.

10. Miscellaneous.

(a) Neither this Subscription Agreement nor any rights that may accrue to the Investor hereunder (other than the Shares acquired hereunder, if any) may be transferred or assigned, other than (i) by prior written consent from NextGen or (ii) an assignment to one or more controlled affiliates, including any fund or account managed by the same investment manager as the Investor or a controlled affiliate thereof, without prior written consent of NextGen, subject to, if such transfer or assignment is prior to the Closing, such transferee or assignee, as applicable, executing a joinder to this Subscription Agreement or a separate subscription agreement in substantially the same form as this Subscription Agreement, including with respect to the Subscription Amount and other terms and conditions; provided that, in the case of any such transfer or assignment, the initial party to this Subscription Agreement shall remain bound by its obligations under this Subscription Agreement in the event that the transferee or assignee, as applicable, does not comply with its obligations to consummate the purchase of Shares contemplated hereby. Neither this Subscription Agreement nor any rights that may accrue to NextGen hereunder or any of NextGen’s obligations may be transferred or assigned other than pursuant to the Transaction.

(b) NextGen may request from the Investor such additional information as NextGen may reasonably deem necessary to evaluate the eligibility of the Investor to acquire the Shares and in connection with the inclusion of the Shares in the Registration Statement, and the Investor shall promptly provide such information as may reasonably be requested, to the extent readily available and to the extent consistent with its internal policies and procedures; provided that, the Investor shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Shares and that NextGen agrees to keep any such information provided by Investor confidential. The Investor acknowledges that NextGen may file a copy of this Subscription Agreement with the SEC as an exhibit to a current or periodic report or a registration statement of NextGen to the extent required by law or regulation.

(c) The Investor acknowledges that NextGen and the Placement Agent (as a third-party beneficiary with the right to enforce Section 4, Section 5, Section 6, Section 10, and Section 11 hereof on their own behalf and not, for the avoidance of doubt, on behalf of NextGen) will rely on the acknowledgments, understandings, agreements, covenants, representations and warranties of the Investor contained in this Subscription Agreement. Prior to the Closing, the Investor agrees to promptly notify NextGen and the Placement Agent if any of the acknowledgments, understandings, agreements, representations and warranties of the Investor set forth herein are no longer accurate.

(d) NextGen acknowledges that the Investor and the Placement Agent (as a third-party beneficiary with the right to enforce Section 4, Section 5, Section 6, Section 10, and Section 11 hereof on their own behalf and not, for the avoidance of doubt, on behalf of the Investor) will rely on the acknowledgments, understandings, agreements, covenants, representations and warranties of NextGen contained in this Subscription Agreement. Prior to the Closing, NextGen agrees to promptly notify the Investor and the Placement Agent if any of the acknowledgments, understandings, agreements, representations and warranties of NextGen set forth herein are no longer accurate.

(e) NextGen, the Placement Agent and the Investor are each entitled to rely upon this Subscription Agreement and each is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby to the extent required by law or regulation.

(f) All of the representations and warranties contained in this Subscription Agreement shall survive the Closing. All of the covenants and agreements made by each party in this Subscription Agreement shall survive the Closing until the applicable statute of limitations or in accordance with their respective terms, if a shorter period.

(g) This Subscription Agreement may not be modified, waived or terminated (other than pursuant to the terms of Section 8 above) except by an instrument in writing, signed by each of the parties hereto. No failure or delay of either party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties and third-party beneficiaries hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

(h) This Subscription Agreement (including the schedule hereto) constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof. Except as set forth in Sections 10(c) and 10(d) with respect to the persons referenced therein, this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successor and assigns.

(i) Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns.

(j) If any provision of this Subscription Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(k) Each party shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated hereby.

(l) The obligations of the Investor under this Subscription Agreement are several and not joint with the obligations of any other investor under the Other Subscription Agreements, and the Investor shall not be responsible in any way for the performance of the obligations of any other investor under any Other Subscription Agreement. The decision of the Investor to purchase the Shares pursuant to this Subscription Agreement has been made by the Investor independently of any other investor and independently of any information, materials, statements opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of NextGen, the Company or any of their respective subsidiaries which may have been made or given by any other investor or by any agent or employee of any other investor, and neither the Investor nor any of its agents or employees shall have any liability to any other investor relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement, and no action taken by the Investor or any other investor pursuant hereto or thereto, shall be deemed to constitute the Investor and any other investor as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investor and any other investor are in any way acting in concert or as a “group” (within the meaning of Section 13(d) of the Exchange Act) with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. The Investor acknowledges that no other investor has acted as agent for the Investor in connection with making its investment hereunder and no other investor will be acting as agent of the Investor in connection with monitoring its investment in the Shares or enforcing its rights under this Subscription Agreement.

(m) This Subscription Agreement may be executed in one or more counterparts (including by electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(n) The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement, without posting a bond or undertaking and without proof of damages, to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise.

(o) THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURT OF CHANCERY OF THE STATE OF DELAWARE (OR, TO THE EXTENT SUCH COURT DOES NOT HAVE SUBJECT MATTER JURISDICTION, THE SUPERIOR COURT OF THE STATE OF DELAWARE, OR THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF DELAWARE) SOLELY IN RESPECT OF THE

INTERPRETATION AND ENFORCEMENT OF THE PROVISIONS OF THIS SUBSCRIPTION AGREEMENT AND THE DOCUMENTS REFERRED TO IN THIS SUBSCRIPTION AGREEMENT AND IN RESPECT OF THE TRANSACTIONS CONTEMPLATED HEREBY, AND HEREBY WAIVE, AND AGREE NOT TO ASSERT, AS A DEFENSE IN ANY ACTION, SUIT OR PROCEEDING FOR INTERPRETATION OR ENFORCEMENT HEREOF OR ANY SUCH DOCUMENT THAT IS NOT SUBJECT THERETO OR THAT SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SAID COURTS OR THAT VENUE THEREOF MAY NOT BE APPROPRIATE OR THAT THIS SUBSCRIPTION AGREEMENT OR ANY SUCH DOCUMENT MAY NOT BE ENFORCED IN OR BY SUCH COURTS, AND THE PARTIES HERETO IRREVOCABLY AGREE THAT ALL CLAIMS WITH RESPECT TO SUCH ACTION, SUIT OR PROCEEDING SHALL BE HEARD AND DETERMINED BY SUCH A DELAWARE STATE OR FEDERAL COURT. THE PARTIES HEREBY CONSENT TO AND GRANT ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND AGREE THAT MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH ACTION, SUIT OR PROCEEDING IN THE MANNER PROVIDED IN THIS SECTION 10(o) OF THIS SUBSCRIPTION AGREEMENT OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE THEREOF. THIS SUBSCRIPTION AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THAT WOULD OTHERWISE REQUIRED THE APPLICATION OF THE LAW OF ANY OTHER STATE.

(p) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS SUBSCRIPTION AGREEMENT.
