2.1.1  Shelf
Registration. The Company agrees that, within thirty (30) days after the consummation of the Business Combination, the Company
will file with the Commission (at the Company’s sole cost and expense) a Registration Statement registering the resale or
other disposition of the Registrable Securities (a “Shelf Registration”).

 

2.1.2  Effective
Registration. The Company shall use its reasonable best efforts to cause such Registration Statement to become effective by
the Commission as soon as reasonably practicable after the initial filing of the Registration Statement. Subject to the limitations
contained in this Agreement, the Company shall effect any Shelf Registration on such appropriate registration form of the Commission
(a) as shall be selected by the Company and (b) as shall permit the resale or other disposition of the Registrable Securities
by the Holders. If at any time a Registration Statement filed with the Commission pursuant to Section 2.1.1 is effective
and a Holder provides written notice to the Company that it intends to effect an offering of all or part of the Registrable Securities
included on such Registration Statement, the Company will use its reasonable best efforts to amend or supplement such Registration
Statement as may be necessary in order to enable such offering to take place in accordance with the terms of this Agreement.

 

2.1.3  Underwritten
Offering. Subject to the provisions of subsection 2.1.4 and Section 2.3 hereof, any Demanding Holder
may make a written demand for an Underwritten Offering pursuant to a Registration Statement filed with the Commission in accordance
with Section 2.1.1 (an “Underwritten Demand”). The Company shall, within five (5) business days
of the Company’s receipt of the Underwritten Demand, notify, in writing, all other Holders of such demand, and each Holder
who thereafter requests to include all or a portion of such Holder’s Registrable Securities in such Underwritten Offering
pursuant to such Underwritten Demand (each such Holder that requests to include all or a portion of such Holder’s Registrable
Securities in such Underwritten Offering, a “Requesting Holder”) shall so notify the Company, in writing,
within two (2) days (one (1) day if such offering is an overnight or bought Underwritten Offering) after the receipt
by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s),
such Requesting Holder(s) shall be entitled to have their Registrable Securities included in such Underwritten Offering pursuant
to such Underwritten Demand. All such Holders proposing to distribute their Registrable Securities through such Underwritten Offering
under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected
for such Underwritten Offering by the Demanding Holders initiating such Underwritten Offering. Notwithstanding the foregoing,
the Company is not obligated to effect more than an aggregate of three (3) Underwritten Offerings pursuant to this subsection 2.1.3
and is not obligated to effect an Underwritten Offering pursuant to this subsection 2.1.3 within ninety (90) days
after the closing of an Underwritten Offering.

 

    5

     

    

 

2.1.4  Reduction
of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Offering pursuant to an Underwritten
Demand, in good faith, advises the Company, the Demanding Holders, the Requesting Holders and other persons or entities holding
Ordinary Shares or other equity securities of the Company that the Company is obligated to include pursuant to separate written
contractual arrangements with such persons or entities (if any) in writing that the dollar amount or number of Registrable Securities
or other equity securities of the Company requested to be included in such Underwritten Offering exceeds the maximum dollar amount
or maximum number of equity securities of the Company that can be sold in the Underwritten Offering without adversely affecting
the proposed offering price, the timing, the distribution method or the probability of success of such offering (such maximum
dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”),
then the Company shall include in such Underwritten Offering, as follows: (a) first, the Registrable Securities of the Demanding
Holders (pro rata based on the respective number of Registrable Securities that each Demanding Holder has requested be included
in such Underwritten Offering and the aggregate number of Registrable Securities that the Demanding Holders have requested be
included in such Underwritten Offering (such proportion is referred to herein as “Pro Rata”)) that can
be sold without exceeding the Maximum Number of Securities; (b) second, to the extent that the Maximum Number of Securities
has not been reached under the foregoing clause (a), the Registrable Securities of the Requesting Holders, Pro Rata,
which can be sold without exceeding the Maximum Number of Securities; (c) third, to the extent that the Maximum Number of Securities
has not been reached under the foregoing clauses (a) and (b), Ordinary Shares or other equity securities of
the Company that the Company desires to sell and that can be sold without exceeding the Maximum Number of Securities; and (d) fourth,
to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (a), (b)
and (c), Ordinary Shares or other equity securities of the Company held by other persons or entities that the Company
is obligated to include pursuant to separate written contractual arrangements with such persons or entities and that can be sold
without exceeding the Maximum Number of Securities.

 

2.2  Piggyback
Registration.

 

2.2.1  Piggyback
Rights. Subject to the provisions of subsection 2.2.2 and Section 2.3 hereof, if, at any time on or
after the date the Company consummates a Business Combination, the Company proposes to consummate an Underwritten Offering
for its own account or for the account of shareholders of the Company, then the Company shall give written notice of such proposed
action to all of the Holders as soon as practicable, which notice shall (a) describe the amount and type of securities to
be included, the intended method(s) of distribution and the name of the proposed managing Underwriter or Underwriters, if any,
and (b) offer to all of the Holders the opportunity to include of such number of Registrable Securities as such Holders may
request in writing within  two (2) days (unless such offering is an overnight or bought Underwritten Offering, then
one (1) day), in each case after receipt of such written notice (such Registration a “Piggyback Registration”).
The Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and shall use
its reasonable best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the
Registrable Securities requested by the Holders pursuant to this subsection 2.2.1 to be included in a Piggyback Registration
on the same terms and conditions as any similar securities of the Company included in such Piggyback Registration and to permit
the resale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof.
All such Holders proposing to include Registrable Securities in an Underwritten Offering under this subsection 2.2.1
shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by
the Company.

 

    6

     

    

 

2.2.2  Reduction
of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback
Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggyback Registration
in writing that the dollar amount or number of shares or equity securities of the Company that the Company desires to sell, taken
together with (a) the shares or equity securities of the Company, if any, as to which the Underwritten Offering has been
demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable
Securities hereunder, (b) the Registrable Securities as to which a Piggyback Registration has been requested pursuant to
Section 2.2 hereof and (c) the shares or equity securities of the Company, if any, as to which inclusion in the
Underwritten Offering has been requested pursuant to separate written contractual piggyback registration rights of other shareholders
of the Company, exceeds the Maximum Number of Securities, then:

 

(i)  If
the Underwritten Offering is undertaken for the Company’s account, the Company shall include in any such Underwritten Offering
(A) first, the Ordinary Shares or other equity securities of the Company that the Company desires to sell, which can be sold
without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not
been reached under the foregoing clause (A), the Registrable Securities of Holders requesting a Piggyback Registration
pursuant to subsection 2.2.1 hereof, Pro Rata, which can be sold without exceeding the Maximum Number of Securities;
and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A)
and (B), Ordinary Shares or other equity securities of the Company, if any, as to which inclusion in the Underwritten
Offering has been requested pursuant to written contractual piggyback registration rights of other shareholders of the Company,
which can be sold without exceeding the Maximum Number of Securities; or

 

(ii)  If
the Underwritten Offering is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then
the Company shall include in any such Underwritten Offering (A) first, Ordinary Shares or other equity securities of the
Company, if any, of such requesting persons or entities, other than the Holders, which can be sold without exceeding the Maximum
Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing
clause (A), the Registrable Securities of Holders requesting a Piggyback Registration pursuant to subsection 2.2.1,
Pro Rata, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum
Number of Securities has not been reached under the foregoing clauses (A) and (B), Ordinary Shares or
other equity securities of the Company that the Company desires to sell, which can be sold without exceeding the Maximum Number
of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing
clauses (A), (B) and (C), Ordinary Shares or other equity securities of the Company for the
account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements
with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

 

2.2.3  Piggyback
Registration Withdrawal. Any Holder shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever
upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw
from such Piggyback Registration prior to the commencement of the Underwritten Offering. Notwithstanding anything to the contrary
in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration
prior to its withdrawal under this subsection 2.2.3.

 

    7

     

    

 

2.2.4  Unlimited
Piggyback Registration Rights. For purposes of clarity, any Registration or Underwritten Offering effected pursuant to Section 2.2
hereof shall not be counted as an Underwritten Offering pursuant to an Underwritten Demand effected under Section 2.1
hereof.

 

2.3  Restrictions
on Registration Rights. If (a) the Holders have requested an Underwritten Offering pursuant to an Underwritten Demand
and the Company and the Holders are unable to obtain the commitment of underwriters to firmly underwrite the offer; or (b) the
Holders have requested an Underwritten Offering pursuant to an Underwritten Demand and in the good faith judgment of the Board
such Underwritten Offering would be seriously detrimental to the Company and the Board concludes as a result that it is essential
to defer the undertaking of such Underwritten Offering at such time, then in each case the Company shall furnish to such Holders
a certificate signed by the Chairman of the Board stating that in the good faith judgment of the Board it would be seriously detrimental
to the Company to undertake such Underwritten Offering in the near future and that it is therefore essential to defer the undertaking
of such Underwritten Offering. In such event, the Company shall have the right to defer such offering for a period of not more
than thirty (30) days; provided, however, that the Company shall not defer its obligation in this manner more than once in any
twelve (12)-month period.

3.2  Registration
Expenses. The Registration Expenses in respect of all Registrations shall be borne by the Company. It is acknowledged

(it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable
after the time of such notice), or until he, she or it is advised in writing by the Company that the use of the Registration Statement
or Prospectus may be resumed. If the filing, initial effectiveness or continued use of a Registration Statement in respect of
any Registration or Underwritten Offering at any time would require the Company to make an Adverse Disclosure or would require
the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the
Company’s control, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or
initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time, but in no event more
than thirty (30) days, determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises
its rights under the preceding sentences in this Section 3.4, the Holders agree to suspend, immediately upon their
receipt of the notices referred to in this Section 3.4, their use of the Registration Statement or Prospectus in connection
with any resale or other disposition of Registrable Securities. The Company shall immediately notify the Holders of the expiration
of any period during which it exercised its rights under this Section 3.4.

 

3.5  Reporting
Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting
company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable
grace period) all reports required to be filed by the Company after the date hereof pursuant to Section 13(a) or 15(d) of
the Exchange Act. The Company further covenants that it shall take such further action as any Holder may reasonably request, all
to the extent required from time to time to enable such Holder to resell or otherwise dispose of Registrable Securities held by
such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated
under the Securities Act (or any successor rule promulgated thereafter by the Commission), including providing any legal opinions.
Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer
as to whether it has complied with such requirements.

Article 4

INDEMNIFICATION AND CONTRIBUTION

 

4.1  Indemnification.

 

4.1.1  The
Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors, employees,
advisors, agents, representatives, members and each person who controls such Holder (within the meaning of the Securities Act)
(collectively, the “Holder Indemnified Persons”) against all losses, claims, damages, liabilities and
expenses (including reasonable attorneys’ fees and inclusive of all reasonable attorneys’ fees arising out of the
enforcement of each such persons’ rights under this Section 4.1) resulting from any Misstatement, except insofar
as the same are caused by or contained or included in any information furnished in writing to the Company by or on behalf of such
Holder Indemnified Person specifically for use therein.

 

4.1.2  In
connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish
to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such
Registration Statement or Prospectus and, to the extent permitted by law, shall, severally and not jointly, indemnify the Company,
its officers, directors, employees, advisors, agents, representatives and each person who controls the Company (within the meaning
of the Securities Act) against any losses, claims, damages, liabilities and expenses (including reasonable attorneys’ fees
and inclusive of all reasonable attorneys’ fees arising out of the enforcement of each such persons’ rights under
this Section 4.1) resulting from any Misstatement, but only to the extent that the same are made in reliance on and
in conformity with information relating to the Holder so furnished in writing to the Company by or on behalf of such Holder specifically
for use therein. In no event shall the liability of any selling Holder hereunder be greater in amount than the net proceeds received
by such Holder from the sale of Registrable Securities pursuant to such Registration Statement giving rise to such indemnification
obligation.

 

4.1.3  Any
person 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
right to indemnification hereunder to the extent such failure has not materially 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 or there may be reasonable defenses available to the indemnified party that are different
from or additional to those available to the indemnifying party, 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 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.

 

    12

     

    

 

4.1.4  The
indemnification provided for under this 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, employee, advisor, agent, representative, member or controlling
person of such indemnified party and shall survive the transfer of securities.

 

4.1.5  If
the indemnification provided under Section 4.1 is held by a court of competent jurisdiction to be unavailable to 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 to the extent permitted by law 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 a court of law by reference to, among
other things, whether the Misstatement relates to information supplied by such indemnifying party or such 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; provided, however, that the liability of any Holder under this subsection 4.1.5
shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. 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 subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal
or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties
hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined
by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred
to in this subsection 4.1.5. 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 subsection 4.1.5 from any person who was
not guilty of such fraudulent misrepresentation.

require the consent of each such Holder so affected. No course of dealing between any Holder or the Company and any other party
hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement
shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights
or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies
hereunder or thereunder by such party.

 

5.6  Other

the Company to register any securities of the Company for sale or to include such securities of the Company in any Registration

		Re:	Administrative
Services Agreement

 

Ladies
and Gentlemen:

 

This
letter agreement by and between Tortoise Acquisition Corp. II (the “Company”) and Tortoise Capital Advisors,
L.L.C. (“Tortoise Capital Advisors”), dated as of the date hereof, will confirm our agreement that,
commencing on the date the securities of the Company are first listed on the New York Stock Exchange (the “Listing
Date”), pursuant to a Registration Statement on Form S-1 and prospectus filed with the Securities and Exchange Commission
(the “Registration Statement”) and continuing until the earlier of the consummation by the Company of
an initial business combination and the Company’s liquidation (in each case as described in the Registration Statement)
(such earlier date hereinafter referred to as the “Termination Date”):

 

(i) Tortoise
Capital Advisors shall make available to the Company, at 5100 W. 115th Place, Leawood, KS 66211 (or any successor location
of Tortoise Capital Advisors), certain office space, utilities, secretarial support and administrative services as may be reasonably
required by the Company. In exchange therefor, the Company shall pay Tortoise Capital Advisors the sum of $10,000 per month on
the Listing Date and continuing monthly thereafter until the Termination Date, with any payments with respect of a partial month
pro-rated based on a 30 day month; and

 

(ii) Tortoise
Capital Advisors hereby irrevocably waives any and all right, title, interest, causes of action and claims of any kind (each,
a “Claim”) in or to, and any and all right to seek payment of any amounts due to it out of, the trust
account established for the benefit of the public shareholders of the Company and into which substantially all of the proceeds
of the Company’s initial public offering will be deposited (the “Trust Account”), and hereby irrevocably
waives any Claim it may have in the future as a result of, or arising out of, this letter agreement, which Claim would reduce,
encumber or otherwise adversely affect the Trust Account or any monies or other assets in the Trust Account, and further agrees
not to seek recourse, reimbursement, payment or satisfaction of any Claim against the Trust Account or any monies or other assets
in the Trust Account for any reason whatsoever.

 

This
letter agreement constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter and
supersedes all prior understandings, agreements or representations by or among the parties hereto, written or oral, to the extent
they relate in any way to the subject matter hereof or the transactions contemplated hereby.

 

This
letter agreement may not be amended, modified or waived as to any particular provision, except by a written instrument executed
by the parties hereto.

 

No
party hereto may assign either this letter agreement or any of its rights, interests or obligations hereunder without the prior
written approval of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and
shall not operate to transfer or assign any interest or title to the purported assignee.

 

This
letter agreement, the entire relationship of the parties hereto, and any litigation between the parties (whether grounded in contract,
tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the
State of New York, without giving effect to its choice of laws principles.
