Terrapin 4 Acquisition Corporation

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 between Terrapin 4 Acquisition Corporation, a Delaware corporation (the “Company”),
and Nomura Securities International, Inc., as representative (the “Representative”) of the several underwriters
(each an “Underwriter” and collectively, the “Underwriters”), relating to an
underwritten initial public offering (the “Public Offering”), of 23,000,000 of the Company’s units
(including up to 3,000,000 units that may be purchased to cover over-allotments, if any) (the “Units”),
each comprised of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Class A
Common Stock”), and one warrant (the “Warrants”). Each Warrant entitles the holder thereof
to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment. The Units shall be sold in
the Public Offering pursuant to a registration statement on Form S-1 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 NASDAQ Capital Market. Certain capitalized terms used herein are defined in paragraph 13
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, Terrapin 4 Sponsor Partnership, LLC (the “Sponsor”),
Terrapin Partners Employee Partnership 4, LLC (“TPEP”) and each of the undersigned individuals, each
of whom is a member of the Company’s board of directors and/or management team (together with TPEP, each, an “Insider”
and collectively, the “Insiders”) and the Representative, hereby agrees with the Company as follows:


 


1. The Sponsor, the Representative and each
Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection with such
proposed Business Combination, it he or she shall (i) vote any shares of Common Stock owned by it, him or her in favor of any proposed
Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in connection with such stockholder
approval.


 


2. The Sponsor and each Insider hereby agrees
that in the event that the Company fails to consummate a Business Combination (as defined in the Underwriting Agreement) within
24 months from the date of the closing of the Public Offering, or such longer period approved by the Company’s stockholders
in accordance with the Company’s amended and restated certificate of incorporation, 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 therefore, redeem 100% of
the Class A Common Stock 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 earned
on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income taxes and fund
its working capital requirements (less up to $50,000 of interest to pay dissolution expenses), divided by the number of then outstanding
Offering Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (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 stockholders and the Company’s board
of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for
claims of creditors and other requirements of applicable law. The Sponsor, the Representative and each Insider agree to not propose
any amendment to the Company’s amended and restated certificate of incorporation 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 from the closing of the Public Offering, unless the Company provides its Public Stockholders 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 franchise and income taxes or fund its working capital requirements, divided by the number of
then outstanding Offering Shares.


 






     


     


    

 


The Sponsor, the Representative 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, held
by it, him or her. The Sponsor, the Representative and each Insider hereby further waives, with respect to any shares of Class
A Common Stock held by it, him or her, if any, 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 stockholder vote to approve
such Business Combination or in the context of a tender offer made by the Company to purchase shares of Class A Common Stock (although
the Sponsor, the Representative and the Insiders and their respective affiliates shall be entitled to redemption and liquidation
rights with respect to any Offering Shares it or they hold if the Company fails to consummate a Business Combination within 24
months from the date of the closing of the Public Offering).


 


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 the Representative, (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, and
the rules and regulations of the Commission promulgated thereunder, with respect to any Units, shares of Common Stock, Warrants
or any securities convertible into, or exercisable, or exchangeable for, shares of Class A Common Stock owned by it, him or her,
(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, shares of Common Stock, Warrants or any securities convertible into, or exercisable, or exchangeable
for, shares of Common Stock owned by it, him or her, 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).


 


4. In the event of the liquidation of the
Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other shareholders, members or managers
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 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 for a 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 (i) $10.00 per share of the Offering Shares or (ii) such lesser 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, net of the amount of interest earned on the property in the Trust Account which may be withdrawn
to pay taxes, and interest released to the Company to fund its working capital requirements, except as to any claims by a third
party (including a Target) who executed a waiver of any and all rights to seek access to the Trust Account and except as to any
claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities
Act of 1933, as amended. In the event that any such executed waiver is deemed to be unenforceable against such third party, the
Sponsor shall not be responsible to the extent of any liability for such third party claims. 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 less than an aggregate
of 5,065,494 shares of Class A Common Stock (the “Forward Purchase Shares”), or no Forward Purchase Shares,
are purchased by the Representative (collectively with its permitted assignees under the Forward Purchase Agreement, as defined
below) concurrently with the consummation of the initial Business Combination pursuant to that certain Forward Purchase Agreement,
dated as of ______, 2018, between the Company, the Representative, and the Sponsor (the “Forward Purchase Agreement”):


 


(a) the Sponsor agrees to forfeit, at no
cost, a number of Founder Shares in the aggregate equal to the product of 797,765 multiplied by a fraction, (i) the numerator of
which is the number of Forward Purchase Shares purchased by the Representative (collectively with any of its permitted assignees
under the Forward Purchase Agreement), and (ii) the denominator of which is 5,065,494;


 


(b) TPEP agrees to forfeit, at no cost,
a number of Founder Shares in the aggregate equal to the product of 164,678 multiplied by a fraction, (i) the numerator of which
is the number of Forward Purchase Shares purchased by the Representative (collectively with any of its permitted assignees under
the Forward Purchase Agreement), and (ii) the denominator of which is 5,065,494; and


 


(c) the Representative agrees to forfeit,
at no cost, a number of Founder Shares in the aggregate equal to the product of 303,930 multiplied by a fraction, (i) the numerator
of which is the number of Forward Purchase Shares purchased by the Representative (collectively with any of its permitted assignees
under the Forward Purchase Agreement), and (ii) the denominator of which is 5,065,494.


 


6. To the extent that the Underwriters do
not exercise their option to purchase up to an additional 3,000,000 Units to cover over-allotments within 45 days from the date
of the Prospectus (and as further described in the Prospectus):


 


(a) the Sponsor agrees to forfeit, at no
cost, a number of Founder Shares in the aggregate equal to the product of 621,672 multiplied by a fraction, (i) the numerator of
which is 3,000,000 minus the number of Units purchased by the Underwriters upon the exercise of their option to purchase additional
Units, and (ii) the denominator of which is 3,000,000; and


 


(b) TPEP agrees to forfeit, at no cost,
a number of Founder Shares in the aggregate equal to the product of 128,328 multiplied by a fraction, (i) the numerator of which
is 3,000,000 minus the number of Units purchased by the Underwriters upon the exercise of their option to purchase additional Units,
and (ii) the denominator of which is 3,000,000.


 


The forfeiture will be adjusted to the extent
that the over-allotment option is not exercised in full by the Underwriters so that the holders of the Founder Shares will own
an aggregate of 20.0% of the Company’s issued and outstanding shares of Common Stock after the Public Offering.


 


7. (a) The Sponsor and each Insider hereby
agrees not to participate in the formation of, or become an officer or director of, any other blank check company that is seeking
an initial business combination requiring total consideration to the seller of less than $1.25 billion 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 after the closing of the Public Offering.


 


(b) The Sponsor, each Insider and the Representative
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, an Insider or the Representative of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 6, 7(a),
8(a), 8(b) and 10, (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.


 


8. (a) The Sponsor, the Representative and
each Insider agrees that it, he or she shall not Transfer any Founder Shares (or shares of Common Stock issuable upon conversion
thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination or (B) subsequent
to the Business Combination, (x) if the last sale price of the Class A Common Stock equals or exceeds $12.00 per share (as adjusted
for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading
day period commencing at least 150 days after the Company’s initial Business Combination or (y) the date on which the Company
completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the
Company’s stockholders having the right to exchange their shares of Class A Common Stock for cash, securities or other property
(the “Founder Shares Lock-up Period”).


 






    3 


     


    

 


(b) The Sponsor and each Insider agrees
that it, he or she shall not Transfer any Private Placement Warrants (or shares of Class A Common Stock issued or issuable upon
the exercise of the Private Placement Warrants) until 30 days after the completion of a Business Combination (the “Private
Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).


 


(c) Notwithstanding the provisions set forth
in paragraphs 8(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and shares of Class A Common Stock issued
or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares and that are held by the Sponsor,

(a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors,
any members of the Sponsor, or any affiliates of the Sponsor; (b) in the case of an individual, by gift to a member of the individual’s

such person, or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of descent and
distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic relations
order; (e) 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; (f) transfers in the event of the Company’s liquidation
prior to the completion of an initial Business Combination; (g) by virtue of the laws of the State of Delaware or the Sponsor’s
limited liability company agreement upon dissolution of the Sponsor; or (h) in the event of the Company’s liquidation,
merger, capital stock exchange, reorganization, or other similar transaction which results in all of the Company’s stockholders
having the right to exchange their shares of Class A Common Stock for cash, securities or other property subsequent to the completion
of a Business Combination; provided, however, that in the case of clauses (a) through (e) and (g) these permitted
transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.


 


9. The Sponsor and each Insider represents
and warrants that it, he or she has never been suspended or expelled from membership in any securities or commodities exchange
or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical
information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all respects

10. Except as disclosed in the Prospectus,

fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection
with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless
of the type of transaction that it is), other than the following, none of which will be made from the proceeds held in the Trust

as to be determined by the Company from time to time, made by the Sponsor or an affiliate of the Sponsor or certain of the Company’s

    4 


     


    

 


11. If, in connection with the closing of
an initial Business Combination, the Sponsor agrees to forfeit any Founder Shares to the Company at no cost (other than pursuant
to paragraph 5(a)) or subject its Founder Shares to contractual terms or restrictions, convert its Founder Shares into other securities
or contractual rights or otherwise modify the terms of its Founder Shares, then, provided that the Sponsor is not being issued
any other equity or equity-related securities or other items of value in such Business Combination in consideration for such forfeiture
or conversion that are not also being issued to the parties to the Forward Purchase Agreement on a pro rata basis (other than in
respect of its Private Placement Warrants or loans to the Company for working capital and any grants of equity or equity-related
securities as director fees), the Representative agrees to forfeit, subject, convert or modify its Founder Shares on a pro rata
basis and on the same terms as the Sponsor, and hereby grants to the Company and any representative designated by the Company without
further action by the Representative a limited irrevocable power of attorney to effect such forfeiture or conversion on behalf
of the Representative, which power of attorney shall be deemed to be coupled with an interest.


 


12. The Sponsor and each Insider has full
right and power, without violating any agreement to which it is bound (including, without limitation, any noncompetition or non-solicitation
agreement with any employer or former employer), to enter into this Letter Agreement, as applicable, to serve as an officer and/or
a director on the board of directors of the Company and hereby consents to being named in the Prospectus as an officer and/or a

16. Nothing in this Letter Agreement shall
be construed to confer upon, or give to, any person or corporation other than the parties hereto any right, remedy or claim under
