Exhibit 10.4

Execution Version

This SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into this 7th day of February, 2021, by and between Tortoise Acquisition Corp. II, a Cayman Islands exempted company (the “Issuer”), and the undersigned (“Subscriber”).

WHEREAS, substantially concurrently with the execution and delivery of this Subscription Agreement, the Issuer is entering into that certain Business Combination Agreement and Plan of Reorganization, dated as of the date of this Subscription Agreement (as may be amended or supplemented from time to time, the “Combination Agreement”), among the Issuer, SNPR Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of the Issuer, SNPR Merger Sub II, LLC, a Delaware limited liability company and a wholly owned subsidiary of the Issuer, and Volta Industries, Inc., a Delaware corporation (“Volta”), pursuant to which, among other things, the Issuer will acquire Volta, on the terms and subject to the conditions set forth therein (the “Transaction”);

WHEREAS, prior to the closing of the Transaction (and as more fully described in the Combination Agreement), the Issuer will domesticate as a Delaware corporation in accordance with Section 388 of the Delaware General Corporation Law and the applicable provisions of the Cayman Islands Companies Act (2021 Revision) (the “Domestication”);

WHEREAS, in connection with the Transaction, the Issuer is seeking commitments from interested investors to purchase, following the Domestication and prior to the closing of the Transaction, the Issuer’s Class A common stock following the Domestication (the “Class A Shares”);

WHEREAS, in connection with the Transaction, on the terms and subject to the conditions set forth in this Subscription Agreement, Subscriber desires to subscribe for and purchase from the Issuer the number of Class A Shares, set forth on the signature page hereto (the “Acquired Shares”) for a purchase price of $10.00 per share (the “Share Purchase Price” and the aggregate purchase price set forth on the signature page hereto for the Acquired Shares, the “Purchase Price”), and the Issuer desires to issue and sell to Subscriber the Acquired Shares in consideration of the payment of the Purchase Price by or on behalf of Subscriber to the Issuer at or prior to the Closing (as defined herein); and

WHEREAS, in connection with the Transaction, certain institutional “accredited investors” (as such term is defined in Rule 501 under the Securities Act of 1933, as amended (the “Securities Act”)) other than Subscriber (each, an “Other Subscriber”), have entered into subscription agreements with the Issuer substantially similar to this Subscription Agreement, pursuant to which such Other Subscribers have agreed to subscribe for and purchase, and the Issuer has agreed to issue and sell to such Other Subscribers, on the Closing Date (as defined herein), Class A Shares at the Share Purchase Price (the “Other Subscription Agreements”).

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

1. Subscription. Subject to the terms and conditions hereof, Subscriber hereby agrees to subscribe for and purchase, and the Issuer hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Acquired Shares (such subscription and issuance, the “Subscription”). Subscriber acknowledges and agrees that, as a result of the Domestication, the Class A Shares issued pursuant hereto shall be shares of common stock in a Delaware corporation (and not shares in a Cayman Islands exempted company).

2. Closing.

a. Subject to the satisfaction or waiver of the conditions set forth in Sections 2.c and 2.d, the closing of the Subscription contemplated hereby (the “Closing”) shall occur following the Domestication on the date of, and at a time immediately prior to or substantially concurrently with, the closing of the Transaction (such date, the “Closing Date”) and is contingent upon the subsequent occurrence of the closing of the Transaction. Not less than five (5) business days prior to the anticipated Closing Date, the Issuer shall provide written notice to Subscriber (the “Closing Notice”) of the anticipated Closing Date specifying (i) the anticipated Closing Date and (ii) the wire instructions for delivery of the Purchase Price to the Issuer.

b. Subject to the satisfaction or waiver of the conditions set forth in Sections 2.c and 2.d:

(i) Subscriber shall deliver to the Issuer no later than one (1) business day prior to the Closing Date (unless otherwise agreed by the Issuer and Subscriber) (A) the Purchase Price for the Acquired Shares by wire transfer of U.S. dollars in immediately available funds to the account specified by the Issuer in the Closing Notice and (B) any other information that is reasonably requested in the Closing Notice in order for the Issuer to issue the Acquired Shares, including, without limitation, the legal name of the person in whose name such Acquired Shares are to be issued and a duly executed Internal Revenue Service Form W-9 or W-8, as applicable; and

(ii) On the Closing Date, the Issuer shall deliver to Subscriber the Acquired Shares against and upon payment by Subscriber in book entry form, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by Subscriber, as applicable. Each book entry for the Acquired Shares shall contain a legend in substantially the following form:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM. THE HOLDER WILL NOTIFY ANY SUBSEQUENT PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO ABOVE.

c. The Issuer’s obligation to effect the Closing shall be subject to the satisfaction at the Closing, or, to the extent permitted by applicable law, the waiver by the Issuer, of each of the following conditions:

(i) all representations and warranties of Subscriber contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect (as defined herein), which representations and warranties shall be true and correct in all respects) at and as of the Closing, and consummation of the Closing shall constitute a reaffirmation by Subscriber of each of the representations, warranties and agreements of each such party contained in this Subscription Agreement as of the Closing (other than those representations and warranties expressly made as of an earlier date, which shall be true and correct as set forth above as of such earlier date);

(ii) Subscriber shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing, except where the failure of such performance, satisfaction or compliance would not or would not be reasonably expected to prevent, materially delay or materially impair the ability of Subscriber to consummate the Closing;

(iii) no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the Subscription illegal or otherwise preventing or prohibiting consummation of the Subscription; and

(iv) all conditions precedent to the Issuer’s obligation to effect the Transaction set forth in the Combination Agreement shall have been satisfied or waived (as determined by the parties to the Combination 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 Acquired 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 of the Transaction, or (y) will be satisfied by the Closing and the closing of the transactions contemplated by the Other Subscription Agreements).

d. Subscriber’s obligation to effect the Closing shall be subject to the satisfaction at the Closing, or, to the extent permitted by applicable law, the waiver by Subscriber, of each of the following conditions:

(i) all representations and warranties of the Issuer contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Material Adverse Effect (as defined herein), which representations and warranties shall be true and correct in all respects) at and as of the Closing, and consummation of the Closing shall constitute a reaffirmation by the Issuer of each of the representations, warranties and agreements of each such party contained in this Subscription Agreement as of the Closing (other than those representations and warranties expressly made as of an earlier date, which shall be true and correct as set forth above as of such earlier date);

(ii) the Issuer shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing, except where the failure of such performance, satisfaction or compliance would not or would not be reasonably expected to prevent, materially delay, or materially impair the ability of the Issuer to consummate the Closing;

(iv) all conditions precedent to the closing of the Transaction set forth in the Combination Agreement shall have been satisfied or waived (as determined by the parties to the Combination 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 Acquired 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 of the Transaction, or (y) will be satisfied by the Closing and the closing of the transactions contemplated by the Other Subscription Agreements);

(v) no suspension of the qualification of the Class A Shares for offering or sale or trading on the New York Stock Exchange (“NYSE”), and no initiation or threatening of any proceedings for any of such purposes or delisting, shall have occurred, and the Acquired Shares shall be approved for listing on NYSE, subject to official notice of issuance; and

(vi) the Combination Agreement (as the same exists on the date of this Subscription Agreement) shall not have been amended in any manner that would reasonably be expected to materially and adversely affect the economic benefits that Subscriber would reasonably expect to receive under the Subscription Agreement without Subscriber’s prior written consent; provided, that (for the avoidance of doubt), any decrease in the trading price of Issuer’s securities on the NYSE shall not be deemed to constitute, in and of itself, or be taken into account in the determination of whether, the economic benefits that Subscriber would reasonably expect to receive under this Subscription Agreement have been materially and adversely affected (but not the underlying facts or basis for any such decrease in trading price, which may be taken into account).

e. Prior to or at the Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions as the parties reasonably may deem to be practical and necessary in order to consummate the Subscription as contemplated by this Subscription Agreement.

f. In the event that the closing of the Transaction does not occur within five (5) business days of the anticipated Closing Date specified in the Closing Notice, the Issuer shall promptly (but not later than three (3) business days thereafter) return the Purchase Price to Subscriber in immediately available funds to the account specified by Subscriber, and any book entries shall be deemed cancelled. Notwithstanding such return or cancellation, (i) a failure to close on the anticipated Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 2 to be satisfied or waived on or prior to the Closing Date, and (ii) unless and until this Subscription Agreement is terminated in accordance with Section 7 herein, Subscriber shall remain obligated (A) to redeliver funds to the Issuer in escrow following the Issuer’s delivery to Subscriber of a new Closing Notice and (B) to reconsummate the Closing immediately prior to or substantially concurrently with the consummation of the Transaction. For the avoidance of doubt, if any termination hereof occurs after the delivery by Subscriber of the Purchase Price for the Acquired Shares, the Issuer shall promptly (but not later than three (3) business days thereafter) return the Purchase Price to Subscriber without any deduction for or on account of any tax, withholding, charges or set-off.

Assuming the accuracy of Subscriber’s representations and warranties in Section 4, the execution and delivery by the Issuer of the Transaction Documents, and the performance by the Issuer of its obligations under the Transaction Documents, including the issuance and sale of the Acquired Shares and the consummation of the other transactions contemplated herein, do not and 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 the Issuer pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Issuer is a party or by which the Issuer is bound or to which any of the property or assets of the Issuer is subject, which would be reasonably expected to have, individually or in the aggregate, a material adverse effect on the business, properties, financial condition, shareholders’ equity or results of operations of the Issuer (a “Material Adverse Effect”) or materially affect the validity of the Acquired Shares or the legal authority of the Issuer to comply in all material respects with the terms of this Subscription Agreement; (ii) the organizational documents of the Issuer; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Issuer or any of its properties that would be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect or materially affect the validity of the Acquired Shares or the legal authority of the Issuer to comply in all material respects with this Subscription Agreement.

e. Assuming the accuracy of Subscriber’s representations and warranties in Section 4, the Issuer 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 execution, delivery and performance by the Issuer of this Subscription Agreement (including, without limitation, the issuance of the Acquired Shares), other than (i) the filing with the Securities and Exchange Commission (the “Commission”) of the Registration Statement (as defined below), (ii) the filings required by applicable state or federal securities laws, (iii) the filings required in accordance with Section 9.m, (iv) those required by the New York Stock Exchange (the “NYSE”), including with respect to obtaining stockholder approval, and (v) the failure of which to obtain would not be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect or have a material adverse effect of the Issuer’s ability to consummate the transactions contemplated hereby, including the sale and issuance of the Acquired Shares.

f. As of the date hereof, the authorized share capital of the Issuer consists of (i) 1,000,000 preference shares, par value $0.0001 per share, as such shares will exist as preferred stock following the Domestication (the “Preferred Stock”), (ii) 200,000,000 Class A Shares and (iii) 20,000,000 Class B ordinary shares, par value $0.0001 per share, as such shares will exist as Class A common stock following the Domestication (the “Class B Shares”).

g. The issued and outstanding Class A Shares are registered pursuant to Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and are listed for trading on the NYSE. There is no suit, action, proceeding or investigation pending or, to the knowledge of the Issuer, threatened against the Issuer by the NYSE or the Commission with respect to any intention by such entity to deregister the Class A Shares or prohibit or terminate the listing of the Class A Shares on the NYSE. The Issuer has taken no action that is designed to terminate the registration of the Class A Shares under the Exchange Act.

h. Assuming the accuracy of Subscriber’s representations and warranties set forth in Section 4, no registration under the Securities Act is required for the offer and sale of the Acquired Shares by the Issuer to Subscriber in the manner contemplated by this Subscription Agreement.

i. Neither the Issuer nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D of the Securities Act) in connection with any offer or sale of the Acquired Shares.

k. Each report required to be filed by the Issuer with the Commission since its initial registration of the Class A Shares (the “SEC Documents”), as of their respective filing dates, complied in all material respects with the requirements of the Exchange Act applicable to the SEC Documents and the rules and regulations of the Commission promulgated thereunder applicable to the SEC Documents. None of the SEC Documents filed under the Exchange Act (except to the extent that information contained in any SEC Document has been superseded by a later timely filed SEC Document) contained, when filed, any 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, in the case of any SEC Document that is a registration statement, or included, when filed, any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in the case of all other SEC Documents; provided, that, with respect to the proxy statement to be filed by the Issuer with respect to the Transaction or any of its affiliates included in any SEC Document or filed as an exhibit thereto, the representation and warranty in this sentence is made to the Issuer’s knowledge.

l. Except for such matters as have not had and would not be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect, there is no (i) suit, action, proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of the Issuer, threatened against the Issuer or (ii) judgment, decree, injunction, ruling or order of any governmental entity or arbitrator outstanding against the Issuer.

m. There are no securities or instruments issued by the Issuer containing anti-dilution provisions that will be triggered by the issuance of (i) the Acquired Shares or (ii) the Class A Shares to be issued pursuant to any Other Subscription Agreement, in each case, that have not been or will not be validly waived on or prior to the Closing Date.

n. The Issuer is in compliance with all applicable laws, except where such non-compliance would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. The Issuer has not received any written communication from a governmental entity alleging that the Issuer 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, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

o. Neither the Issuer nor Tortoise Sponsor II LLC, a Cayman Islands limited liability company (the “Sponsor”), has entered into any subscription agreement, side letter or other agreement with any Other Subscriber or any other investor in connection with such Other Subscriber’s or investor’s direct or indirect investment in the Issuer other than (i) the Other Subscription Agreements and (ii) the letter agreement, dated September 10, 2020, by and among the Sponsor, the Issuer and the other parties thereto. The Other Subscription Agreements have not been amended in any material respect following the date of this Subscription Agreement and reflect the same Share Purchase Price and other terms with respect to the purchase of the Acquired 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 fund.

4. Subscriber Representations and Warranties. Subscriber represents and warrants that:

Subscriber acknowledges that the Acquired Shares will not be eligible for resale pursuant to Rule 144A promulgated under the Securities Act. Subscriber understands and agrees that the Acquired Shares will be subject to transfer restrictions and, as a result of these transfer restrictions, Subscriber may not be able to readily resell the Acquired Shares and may be required to bear the financial risk of an investment in the Acquired Shares for an indefinite period of time.

Subscriber further acknowledges that there have been no representations, warranties, covenants and agreements made to Subscriber by the Issuer or the Placement Agents or any of the officers or directors of any thereof, expressly or by implication, other than those representations, warranties, covenants and agreements of the Issuer included in this Subscription Agreement.

Subscriber acknowledges that the Issuer represents and warrants that the Acquired Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

j. Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Acquired Shares. Subscriber qualifies as a sophisticated institutional investor and has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment, both in general and with regard to transactions in, and investment strategies involving, securities, including Subscriber’s investment in the Acquired Shares, and Subscriber has sought such accounting, legal and tax advice as Subscriber has considered necessary to make an informed investment decision.

k.

l. Alone, or together with any professional advisor(s), Subscriber represents and acknowledges that Subscriber has adequately analyzed and fully considered the risks of an investment in the Acquired Shares and determined that the Acquired Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Issuer. Subscriber acknowledges specifically that a possibility of total loss exists.

m. Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Acquired Shares or made any findings or determination as to the fairness of an investment in the Acquired Shares.

n.

Subscriber further represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Acquired Shares were legally derived.

o. If Subscriber is or is acting on behalf of (i) an employee benefit plan that is subject to Title I of ERISA, (ii) a plan, an individual retirement account or other arrangement that is subject to section 4975 of the Code, (iii) an entity whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement described in clauses (i) and (ii) (each, an “ERISA Plan”) or (iv) an employee benefit plan that is a governmental plan (as defined in section 3(32) of ERISA), a church plan (as defined in section 3(33) of ERISA), a non-U.S. plan (as described in section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing clauses (i), (ii) or (iii) but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (together with the ERISA Plans, the “Plans”), then Subscriber represents and warrants that it has not relied on the Issuer or any of its affiliates (the ”Transaction Parties”) for investment advice or as the Plan’s fiduciary with respect to its decision to acquire and hold the Acquired Shares, and none of the Transaction Parties is or shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire and hold or transfer the Acquired Shares.

p. Subscriber will have sufficient funds to pay the Purchase Price pursuant to Section 2.b(i) on the Closing Date .

5. Additional Subscriber Agreement. Subscriber hereby agrees that, from the date of this Subscription Agreement until the Closing Date (or earlier termination of this Subscription Agreement), neither Subscriber nor any person or entity acting on behalf of Subscriber or pursuant to any understanding with Subscriber will engage in any Short Sales with respect to securities of the Issuer. For purposes of this Section 5, “Short Sales” shall mean all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all short positions effected through any direct or indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), or sales or other short transactions through non-U.S. broker dealers or foreign regulated brokers. Notwithstanding the foregoing, (a) nothing herein shall prohibit other entities under common management with Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation in the Transaction (including Subscriber’s controlled affiliates and/or affiliates) from entering into any Short Sales and (b) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’s assets, the limitations set forth in the first sentence of this Section 5 shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Acquired Shares covered by this Subscription Agreement.

6. Registration Rights.

a. The Issuer agrees that, within thirty (30) calendar days after the consummation of the Transaction (the “Filing Date”), the Issuer will file with the Commission (at the Issuer’s sole cost and expense) a registration statement registering the resale of the Acquired Shares (the “Registration Statement”), and the Issuer 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 60th calendar day (or 90th calendar day if the Commission notifies the Issuer that it will “review” the Registration Statement) following the Closing and (ii) the 10th business day after the date the Issuer is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such earlier date, the “Effective Date”); provided, however, that the Issuer’s obligations to include the Acquired Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Issuer such information regarding Subscriber, the securities of the Issuer held by Subscriber and the intended method of disposition of the Acquired Shares (which shall be limited to non-underwritten public offerings) as shall be reasonably requested by the Issuer to effect the registration of the Acquired Shares, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Issuer shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder. For purposes of clarification, any failure by the Issuer to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effective Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement as set forth in this Section 6. The Issuer will use its commercially reasonable efforts to provide a draft of the Registration Statement to Subscriber for review (but not comment) at least three (3) Business Days in advance of the date of filing the Registration Statement with the Commission; provided, that for the avoidance of doubt, in no event shall the Issuer be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Subscriber’s review. Notwithstanding the foregoing, if the Commission prevents the Issuer 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 Acquired Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Acquired Shares which is equal to the maximum number of Acquired Shares as is permitted by the Commission. In such event, the number of Acquired Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders. Upon notification by the Commission that the Registration Statement has been declared effective by the Commission, within two (2) business days thereafter, the Issuer shall file the final prospectus under Rule 424 of the Securities Act. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided, that if the Commission requests that Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber will have an opportunity to withdraw from the Registration Statement.

b. In the case of the registration, qualification, exemption or compliance effected by the Issuer pursuant to this Subscription Agreement, the Issuer shall, upon reasonable request, inform Subscriber as to the status of such registration, qualification, exemption and compliance. At its expense the Issuer shall:

(i) except for such times as the Issuer 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 the Issuer determines to obtain, continuously effective with respect to Subscriber, 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: (1) Subscriber ceases to hold any Acquired Shares issued pursuant to this Subscription Agreement, (2) the date all Acquired Shares issued pursuant to this Subscription Agreement and held by Subscriber may be sold without restriction under Rule 144, including, without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 promulgated under the Securities Act and without the requirement for the Issuer to be in compliance with the current public information required under Rule 144(c)(1) or Rule 144(i)(2), as applicable, and (3) two years from the Effective Date of the Registration Statement.

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

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

(2) of any request by the Commission for amendments or supplements to the Registration Statement or the prospectus included therein or for additional information;

(3) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for such purpose;

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

(5) in accordance with Section 6.c of this Subscription Agreement, of the occurrence of any event that requires the making of any changes in the Registration Statement or prospectus so that, as of such date, the Registration Statement does not contain an untrue statement of a material fact or does not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any prospectus does not include an untrue statement of a material fact or does not omit 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.

Notwithstanding anything to the contrary set forth herein, the Issuer shall not, when so advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding the Issuer other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (1) through (5) above constitutes material, nonpublic information regarding the Issuer;

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

(iv) upon the occurrence of any event contemplated above, except for such times as the Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Issuer 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 Acquired Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary in order 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 Acquired Shares to be listed on each securities exchange or market, if any, on which the Class A Shares issued by the Issuer have been listed;

(vi) use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Acquired Shares contemplated hereby and to enable Subscriber to sell the Acquired Shares under Rule 144;

(vii) cause the Issuer’s transfer agent to remove the legend set forth above in Section 2.b(ii), at Subscriber’s request, when the Acquired Shares are sold pursuant to Rule 144 promulgated under the Securities Act or the Registration Statement. In connection therewith, if required by the Issuer’s transfer agent, the Issuer will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to issue such Acquired Shares without any such legend; and

(viii) use its commercially reasonable efforts to cause any book entry evidencing the Acquired Shares to not contain any legend (including the legend set forth above in Section 2.b(ii)), while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act.

c. Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Issuer or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event the Issuer’s board of directors reasonably believes, upon the advice of legal counsel, would require additional disclosure by the Issuer in the Registration Statement of material information that the Issuer 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 the Issuer’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that the Issuer may not delay or suspend the Registration Statement on more than two (2) occasions or for more than ninety (90) consecutive calendar days, or more than one hundred-twenty (120) total calendar days, in each case during any twelve-month period. Upon receipt of any written notice from the Issuer 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 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 not misleading, or any related prospectus includes any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, Subscriber agrees that (i) it will immediately discontinue offers and sales of the Acquired Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Issuer 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 the Issuer 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 the Issuer unless otherwise required by law or subpoena. If so directed by the Issuer, Subscriber will deliver to the Issuer or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Acquired Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Acquired Shares shall not apply (1) to the extent Subscriber is required to retain a copy of such prospectus (x) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (y) in accordance with a bona fide pre-existing document retention policy or (2) to copies stored electronically on archival servers as a result of automatic data back-up. Subscriber 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 Acquired Shares.

d. Subscriber may deliver written notice (an “Opt-Out Notice”) to the Issuer requesting that Subscriber not receive notices from the Issuer otherwise required by this Section 6; provided, however, that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i) the Issuer shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to Subscriber’s intended use of an effective Registration Statement, Subscriber will notify the Issuer 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 6.d) and the related suspension period remains in effect, the Issuer will so notify Subscriber, within one (1) business day of Subscriber’s notification to the Issuer, by delivering to Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such Suspension Event immediately upon its availability.

e. The Issuer shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Subscriber (to the extent a seller under the Registration Statement), the officers, directors, trustees, partners, affiliates, members, managers, stockholders, employees, investment advisors and agents of Subscriber, and each person who controls Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) to the fullest extent permitted by applicable law, from and against any and all out-of-pocket losses, claims, damages, liabilities, costs (including, without limitation, reasonable external attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of a material fact contained in the Registration Statement or in any amendment or supplement thereto, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue or alleged untrue statement of a material fact included in any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission 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 (iii) any violation or alleged violation by the Issuer of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 6, except to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to the Issuer by Subscriber expressly for use therein or Subscriber has omitted a material fact from such information; provided, however, that the indemnification contained in this Section 6 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Issuer (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Issuer be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (1) in reliance upon and in conformity with written information furnished by Subscriber, (2) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by the Issuer in a timely manner or (3) in connection with any offers or sales effected by or on behalf of Subscriber in violation of Section 6.c hereof. The Issuer shall notify Subscriber reasonably promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 6 of which the Issuer receives notice in writing. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the Transfer of the Acquired Shares by Subscriber.

f. Subscriber shall, severally and not jointly with any person that is a party to the Other Subscription Agreements, indemnify and hold harmless the Issuer, its directors, officers, agents and employees, and each person who controls the Issuer (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), to the fullest extent permitted by applicable law, from and against all Losses, as incurred, (i) arising out of or based upon any untrue or alleged untrue statement of a material fact contained any Registration Statement or in any amendment or supplement thereto or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) arising out of or based upon any untrue or alleged untrue statement of a material fact included in any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or (iii) arising out of or relating to any omission or alleged omission of a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, with respect to (i) and/or (ii), to the extent, but only to the extent, that such untrue or alleged untrue statements or omissions or alleged omissions are based upon information regarding Subscriber furnished in writing to the Issuer by Subscriber expressly for use therein; provided, however, that the indemnification contained in this Section 6.f shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed). In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Acquired Shares giving rise to such indemnification obligation. Subscriber shall notify the Issuer promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 6.f of which Subscriber is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the Transfer of the Acquired Shares by Subscriber.

g. If the indemnification provided under Section 6(e) or Section 6(f), as applicable, 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. 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 6(f) and 6(g) 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 6(h) from any person who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 6(h) shall be individual, not joint and several, and in no event shall the liability of any Subscriber hereunder be greater in amount than the dollar amount of the net proceeds received by such Subscriber upon the sale of the Acquired Shares giving rise to such indemnification obligation.

7. 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 earlier to occur of (a) such date and time as the Combination Agreement is terminated in accordance with the terms therein without being consummated, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement or (c) the date that is two hundred ten (210) days after the date hereof, if the Closing has not occurred by such date; 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 such willful breach. The Issuer shall promptly notify in writing Subscriber of the termination of the Combination Agreement promptly after the termination of such agreement.

8. Trust Account Waiver. Subscriber acknowledges that the Issuer is a blank check company with the powers and privileges to effect a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination involving the Issuer and one or more businesses or assets. Subscriber further acknowledges that, as described in the Issuer’s prospectus relating to its initial public offering dated September 10, 2020 (the “Prospectus”), available at xxx.xxx.xxx, substantially all of the Issuer’s assets consist of the cash proceeds of the Issuer’s initial public offering and private placements of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of the Issuer, its public shareholders and the underwriters of the Issuer’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Issuer to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the Prospectus. For and in consideration of the Issuer entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, Subscriber, on behalf of itself and its representatives, hereby irrevocably waives any and all right, title and interest, or any claim of any kind they have or may have in the future arising out of this Subscription Agreement, 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, however, that nothing in this Section 8 shall (x) serve to limit or prohibit Subscriber’s right to pursue a claim against Issuer for legal relief against assets held outside the Trust Account (so long as such claim would not affect Issuer’s ability to fulfill its obligation to effectuate any redemption right with respect to any securities of the Issuer), for specific performance or other equitable relief, (y) serve to limit or prohibit any claims that the Subscriber may have in the future against Issuer’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 Issuer’s ability to fulfill its obligation to effectuate any redemption right with respect to any securities of the Issuer) or (z) be deemed to limit any of Subscriber’s right, title, interest or claim to the Trust Account by virtue of such Subscriber’s record or beneficial ownership of securities of the Issuer acquired by any means other than pursuant to this Subscription Agreement, including, but not limited to, any redemption right with respect to any such securities of the Issuer.

9. Miscellaneous.

a. Each party hereto acknowledges that the other party hereto and the Placement Agents will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement, and that, following the Closing, Volta may rely on the representations and warranties of Subscriber contained in Section 4; provided, however, that this Section 9.a shall not give any such party any rights other than those expressly set forth herein. Prior to the Closing, each party hereto agrees to promptly notify the other party hereto if any of the acknowledgments, understandings, agreements, representations and warranties made by such party as set forth herein are no longer accurate in all material respects. Subscriber further acknowledges and agrees that the Placement Agents are third-party beneficiaries of the representations and warranties of Subscriber contained in Section 4 and the Issuer further acknowledges and agrees that the Placement Agents are third-party beneficiaries of the representations and warranties of the Issuer contained in Section 3.

b. Each of the Issuer and Subscriber is entitled to rely upon this Subscription Agreement and 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 by regulatory bodies.

c. Notwithstanding anything to the contrary in this Subscription Agreement, prior to the Closing, Subscriber may not transfer or assign all or a portion of its rights under this Subscription Agreement, other than to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment manager who acts on behalf of Subscriber) without the prior consent of the Issuer; provided that, such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Subscription Agreement, makes the representations and warranties in Section 4 and completes Schedule A hereto; provided, further, that, no assignment shall relieve the assigning party of any of its obligations hereunder, including any assignment to any fund or account managed by the same investment manager as Subscriber or by an affiliate of such investment manager. In the event of such a transfer or assignment, Subscriber shall complete the form of assignment attached as Schedule B hereto.

d. All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of the Transaction, all representations, warranties, covenants and agreements of the parties hereunder shall survive the consummation of the Transaction and remain in full force and effect.

e. The Issuer may request from Subscriber such additional information as the Issuer may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Acquired Shares, and Subscriber shall promptly provide such information as may be reasonably requested, to the extent readily available and to the extent consistent with its internal policies and procedures; provided that the Issuer agrees to keep any such information provided by Subscriber confidential.

f. This Subscription Agreement 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.

g. 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.

h. If any provision of this Subscription Agreement shall 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.

i. This Subscription Agreement may be executed in two (2) or more counterparts (including by electronic means), all of which shall be considered one and the same agreement and shall become effective when signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

j. Each party shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

k. Any notice or communication required or permitted hereunder shall be in writing and either delivered personally, emailed or telecopied, sent by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, and shall be deemed to be given and received (i) when so delivered personally, (ii) upon receipt of an appropriate electronic answerback or confirmation when so delivered by telecopy (to such number specified below or another number or numbers as such person may subsequently designate by notice given hereunder), (iii) when sent, with no mail undeliverable or other rejection notice, if sent by email, or (iv) five (5) business days after the date of mailing to the address below or to such other address or addresses as such person may hereafter designate by notice given hereunder:

l. This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this Subscription Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement of this Subscription Agreement, shall be governed by and construed in accordance with the Laws of the State of New York, without giving effect to the principles of conflicts of law thereof.

THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, THE SUPREME COURT OF THE STATE OF NEW YORK AND THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA LOCATED IN THE STATE OF NEW YORK 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 NEW YORK STATE OR FEDERAL COURT.
