Re:Initial Public Offering

 

Ladies and Gentlemen:

 

This letter (this “Letter
Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting
Agreement”) entered into by and among Tortoise Acquisition Corp. II, a Cayman Islands exempted company (the “Company”),
and Barclays Capital Inc. and Goldman Sachs & Co. LLC, as representatives (the “Representatives”)
of the several underwriters (the “Underwriters”), relating to an underwritten initial public offering
(the “Public Offering”), of [        ]
of the Company’s units (including up to [        ]
units which may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one of
the Company’s Class A ordinary shares, par value $0.0001 per share (the “Class A Ordinary Shares”),
and one-fourth of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the
holder thereof to purchase one Class A Ordinary Share at a price of $11.50 per share, subject to adjustment. The Units shall be
sold in the Public Offering pursuant to the registration statement on Form S-1 No. 333-248269 and prospectus (the “Prospectus”)
filed by the Company with the Securities and Exchange Commission (the “Commission”) and the Company shall
apply to have the Units listed on the New York Stock Exchange. Certain capitalized terms used herein are defined in paragraph 11
hereof.

 

In order to induce
the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other
good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Tortoise Sponsor II LLC, a Cayman
Islands limited liability company (the “Sponsor”), TortoiseEcofin Borrower LLC, a Delaware limited liability
company (“TortoiseEcofin Borrower”), and each of the undersigned individuals, each of whom is a member
of the Company’s board of directors and/or management team (each an “Insider” and, collectively,
the “Insiders”), hereby agree with the Company as follows:

 

1. The
Sponsor and each Insider agree that if the Company seeks shareholder approval of a proposed Business Combination, then in connection
with such proposed Business Combination, it, he or she shall vote all Founder Shares and any shares acquired by it, him or her
in the Public Offering or the secondary public market in favor of such proposed Business Combination.

 

2. The Sponsor
and each Insider hereby agree that in the event that the Company fails to consummate a Business Combination within 24 months from
the closing of the Public Offering, or 27 months from the closing of the Public Offering if the Company has executed a letter
of intent, agreement in principal or definitive agreement for a Business Combination within 24 months from the closing of the
Public Offering but has not completed the Business Combination within such 24-month period, or such later period approved by the
Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association,
as may be amended from time to time (the “Memorandum and Articles”), the Sponsor and each Insider shall
take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly
as reasonably possible but not more than 10 business days thereafter, subject to lawfully available funds therefor, redeem 100%
of the Class A Ordinary Shares sold as part of the Units in the Public Offering (the “Offering Shares”),
at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest
not previously released to the Company to pay its income taxes (less up to $100,000 of interest to pay dissolution expenses),
divided by the number of then outstanding Offering Shares, which redemption will completely extinguish the Public Shareholders’
rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law and
(iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders
and the Company’s board of directors, dissolve and liquidate, subject, in the case of clauses (ii) and (iii), to the Company’s
obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. The Sponsor
and the Insiders agree to not propose any amendment to the Memorandum and Articles that would affect the substance or timing of
the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within
24 months (or 27 months, as applicable) from the closing of the Public Offering, unless the Company provides its Public Shareholders
with the opportunity to redeem their Offering Shares upon approval of any such amendment at a per share price, payable in cash,
equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account
and not previously released to the Company to pay its income taxes, divided by the number of then outstanding Offering Shares.

 

     

     

    

 

The Sponsor and each
Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust
Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares. The
Sponsor and each Insider hereby further waives, with respect to any of the Ordinary Shares held by it, him or her, any redemption
rights it, he or she may have in connection with the consummation of a Business Combination, including, without limitation, any
such rights available in the context of a shareholder vote to approve such Business Combination or in the context of a tender offer
made by the Company to purchase the Class A Ordinary Shares and in connection with a shareholder vote to amend the Memorandum and
Articles in a manner that would affect the substance or timing of the Company’s obligation to redeem 100% of the Company’s
public shares if the Company has not consummated a Business Combination within 24 months (or 27 months, as applicable) from the
closing of the Public Offering (although the Sponsor, the Insiders and their respective affiliates shall be entitled to redemption
and liquidation rights with respect to any of the Ordinary Shares (other than the Founder Shares) it or they hold if the Company
fails to consummate a Business Combination within 24 months (or 27 months, as applicable) from the date of the closing of the Public
Offering or such later date as may be specified in an amendment to the Memorandum and Articles).

 

3. During
the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the undersigned
shall not, without the prior written consent of Barclays Capital Inc. and Goldman Sachs & Co. LLC, (i) sell, offer to sell,
contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly
or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the
meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the
rules and regulations of the Commission promulgated thereunder, any Units, Class A Ordinary Shares, the Company’s Class B
ordinary shares, par value $0.0001 per share (the “Class B Ordinary Shares” and, together with the Class
A Ordinary Shares, the “Ordinary Shares”), Warrants or any securities convertible into, or exercisable,
or exchangeable for, Class A Ordinary Shares owned by him, her or it; provided, however, that the foregoing shall not apply
to transfers to the Sponsor by the Insiders, (ii) enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of any Units, Class A Ordinary Shares, Founder Shares, Warrants or any
securities convertible into, or exercisable, or exchangeable for, Class A Ordinary Shares owned by him, her or it, whether any
such transaction is to be settled by delivery of such securities, in cash or otherwise or (iii) publicly announce any intention
to effect any transaction specified in clause (i) or (ii). If the undersigned is an officer or director of the Company, the undersigned
further agrees that the forgoing restrictions shall be equally applicable to any issuer-directed Units that the undersigned may
purchase in the Public Offering. Each of the Insiders, TortoiseEcofin Borrower and the Sponsor acknowledges and agrees that, prior
to the effective date of any release or waiver of the restrictions set forth in this paragraph 3, the Company shall announce
the impending release or waiver by press release through a major news service at least two business days before the effective date
of the release or waiver. Any release or waiver granted shall only be effective two business days after the publication date of
such press release. The provisions of this paragraph will not apply if (A) the release or waiver is effected solely to permit a
transfer of securities that is not for consideration and (B) the transferee has agreed in writing to be bound by the same terms
described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

 

    	 	2	 

     

    

 

4. In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any officer,
member or manager of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim,
damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating,
preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may
become subject as a result of any claim by (i) any third party (other than the Company’s independent public accountants)
for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered
into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”);
provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure
that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products
sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (A) $10.00 per share
of the Offering Shares and (B) the actual amount per share of the Offering Shares held in the Trust Account due to reductions in
the value of the trust assets as of the date of the liquidation of the Trust Account, in each case including interest earned on
the funds held in the Trust Account and not previously released to the Company to pay its income taxes, less income taxes payable,
except as to any claims by a third party or Target that executed an agreement waiving claims against and all rights to seek access
to the Trust Account whether or not such agreement is enforceable. In the event that any such executed waiver is deemed to be unenforceable
against such third party, the Sponsor shall not be responsible for any liability as a result of any such third-party claims. Notwithstanding
any of the foregoing, such indemnification of the Company by the Sponsor shall not apply as to any claims under the Company’s
obligation to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as
amended (the “Securities Act”). The Sponsor shall have the right to defend against any such claim with
counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim
to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

 

5. To
the extent that the Underwriters do not exercise their over-allotment option to purchase an additional [        ]
Units (as described in the Prospectus), the Sponsor agrees, upon the expiration or waiver of such option, to forfeit, for cancellation
at no cost, a number of Founder Shares equal to [        ]
multiplied by a fraction, (i) the numerator of which is [        ]
minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator
of which is [        ].
The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that
the Founder Shares will represent 20.0% of the Company’s issued and outstanding Ordinary Shares after the Public Offering.
The Sponsor further agrees that to the extent that (a) the size of the Public Offering is increased or decreased and (b) the Sponsor
has either purchased or sold Ordinary Shares or an adjustment to the number of Founder Shares has been effected by way of a share
sub-division, share dividend, reverse share sub-division, contribution back to capital or otherwise, in each case in connection
with such increase or decrease in the size of the Public Offering, then (A) the references to [        ]
in the numerator and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15.0%
of the number of Class A Ordinary Shares included in the Units issued in the Public Offering and (B) the reference to [        ]
in the formula set forth in the first sentence of this paragraph shall be adjusted to such number of Founder Shares that the Sponsor
would have to collectively return to the Company in order for all holders of Founder Shares to hold an aggregate of 20.0% of the
Company’s issued and outstanding Ordinary Shares after the Public Offering.

 

6.(a) The
Sponsor and each Insider hereby agree not to become an officer or director of any other special purpose acquisition company, other
than Tortoise Acquisition Corp., a Delaware corporation, with a class of securities registered under the Exchange Act until the
Company has entered into a definitive agreement with respect to a Business Combination or the Company has failed to complete a
Business Combination within 24 months (or 27 months, as applicable) after the closing of the Public Offering.

 

(b) Each
of the Sponsor, TortoiseEcofin Borrower and each Insider hereby agrees and acknowledges that: (i) each of the Underwriters and
the Company would be irreparably injured in the event of a breach by the Sponsor of its obligations under paragraphs 1, 2,
3, 4, 5, 6(a), 7(a), and 7(d), by each Insider of his or her obligations under paragraphs 1, 2, 3, 6(a), 7(a) and 7(d) or TortoiseEcofin
Borrower of its obligations under paragraphs 3, 7(b) and 7(d) of this Letter Agreement, (ii) monetary damages may not be an adequate
remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy
that such party may have in law or in equity, in the event of such breach.

 

7.(a) Subject
to the exceptions set forth herein, the Sponsor and each Insider agree not to transfer, assign or sell any Founder Shares or the
Class A Ordinary Shares issuable upon conversion of the Founder shares held by it, him or her until the earlier of (i) one year
after the date of the consummation of a Business Combination and (ii) the earlier to occur of, subsequent to a Business Combination,
(A) the first date on which the last reported sale price of the Class A Ordinary Shares equals or exceeds $12.00 per share (as
adjusted for share sub-divisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within
any 30 trading-day period commencing at least 150 days after the consummation of a Business Combination and (B) the date on which
the Company consummates a subsequent liquidation, merger, share exchange or other similar transaction which results in all of the
Company’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property
(the “Lock-up”).

 

    	 	3	 

     

    

 

(b) Subject
to the exceptions set forth herein, TortoiseEcofin Borrower agrees not to transfer, assign or sell any Private Placement Warrants
or Class A Ordinary Shares underlying such warrants held by it until 30 days after the completion of a Business Combination.

 

(c) Notwithstanding
the provisions set forth in paragraphs 7(a) and (b), transfers of the Founder Shares, Private Placement Warrants and Class
A Ordinary Shares issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares and
that are held by TortoiseEcofin Borrower, the Sponsor, any Insider or any of their permitted transferees, as applicable (that have
complied with any applicable requirements of this paragraph 7(c)), are permitted (i) in the case of TortoiseEcofin Borrower,
the Sponsor, any Insider or any of their permitted transferees, to the Company’s officers or directors, any affiliates or
family members of any of the Company’s officers or directors, the Sponsor, any members of the Sponsor or their affiliates,
any affiliates of the Sponsor, TortoiseEcofin Borrower or any of its affiliates, or any members, officers, directors or employees
of TortoiseEcofin Borrower or its affiliates; (ii) in the case of an individual, by gift to members of the individual’s immediate
family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such
person or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution upon
death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by virtue of
the laws of the Cayman Islands or the State of Delaware, as applicable, the Sponsor’s operating agreement upon dissolution
of the Sponsor or TortoiseEcofin Borrower’s operating agreement upon dissolution of TortoiseEcofin Borrower; (vi) by private
sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which
the securities were originally purchased; (vii) in the event of the Company’s liquidation prior to the completion of a Business
Combination; or (viii) in the event of completion of a liquidation, merger, share exchange or other similar transaction which results
in all of the Company’s shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other
property subsequent to the completion of a Business Combination; provided, however, that in the case of clauses (i) through
(vi), these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.

 

(d) The
Sponsor, TortoiseEcofin Borrower and the Insiders acknowledge and agree that if, in order to consummate any Business Combination,
the holders of Founder Shares or Private Placement Warrants are required to contribute back to the capital of the Company a portion
of any such securities to be cancelled by the Company or transfer any such securities to third parties, the Sponsor, TortoiseEcofin
Borrower and the Insiders will contribute back to the capital of the Company or transfer to such third parties, at no cost, a proportionate
number of Founder Shares or Private Placement Warrants, as applicable, pro rata with the other holders of Founder Shares or Private
Placement Warrants, as applicable.

9. Except
as disclosed in the Prospectus, none of the Sponsor, TortoiseEcofin Borrower, the Insiders or their respective affiliates, shall
receive any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation

Combination (regardless of the type of transaction that it is). However, such persons may receive the following payments, none
of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business Combination:

working capital held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from
the Trust Account are used for such repayment. Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.50
per warrant at the option of the lender. Such warrants shall be identical to the Private Placement Warrants, including as to exercise
price, exercisability and exercise period.

 

10. The
Sponsor, TortoiseEcofin Borrower and each Insider has full right and power, without violating any agreement to which it, he or
she is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer),
to enter into this Letter Agreement and, as applicable, to serve as a director on the board of directors of the Company and each

in a private placement that shall occur simultaneously with the consummation of the Public Offering; (iv) “Public Shareholders”

extent they relate in any way to the subject matter hereof or the transactions contemplated hereby. This Letter Agreement may not
be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except by
a written instrument executed by all parties hereto. Each of the parties hereto hereby acknowledges and agrees that each of Barclays
Capital Inc. and Goldman Sachs & Co. LLC, on behalf of the Underwriters, is a third-party beneficiary of this Letter Agreement.

Representations.

 

(i) The
Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Ordinary Shares

Act.

registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth
