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 OTR Acquisition Corp., a Delaware corporation (the “Company”), and Maxim Group
LLC, 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 11,500,000 of the Company’s units (including up to 1,500,000 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 “Common Stock”), and one-half of one redeemable warrant. Each
whole warrant (a “Warrant”) entitles the holder thereof to purchase one share of Common Stock at a price
of $11.50 per share, subject to adjustment. The Units will be sold in the Public Offering pursuant to a registration statement
on Form S-1 (File No. 333-248093) and prospectus (the “Prospectus”) filed by the Company with the U.S.
Securities and Exchange Commission (the “Commission”) and the Company has applied to have the Units listed
on The Nasdaq Capital Market. 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, each of OTR Acquisition Sponsor LLC (the “Sponsor”)
and the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team or an
advisor of the Company (each, an “Insider” and collectively, the “Insiders”),
hereby agrees with the Company as follows:


 


1. The Sponsor 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 Capital 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. If the Company engages in a tender offer in connection with any proposed Business Combination, the Sponsor
and each Insider agrees that it, he or she will not seek to sell its, his or her shares of Capital Stock to the Company in connection
with such tender offer.


 


2. The Sponsor and
each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within the timeframe set
forth in the Company’s amended and restated certificate of incorporation, as it may be amended from time to time (the “Charter”),
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 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 (as defined below), including
interest earned on the funds held in the Trust Account and not previously released to the Company to pay its 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 all 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 the case of clauses (ii) and (iii) to the Company’s obligations under Delaware law to provide for claims of creditors
and other requirements of applicable law. The Sponsor and each Insider agrees not to propose any amendment to the Charter to modify
(i) the substance or timing of the ability of holders of Offering Shares to seek redemption in connection with a Business Combination
or amendments to the Charter prior thereto or (ii) (A) the Company’s obligation to redeem 100% of the Offering Shares if
the Company does not complete a Business Combination within such time set forth in the Charter or (B) any other provisions relating
to stockholders' rights or pre-initial Business Combination activity, unless the Company provides its public stockholders with
the opportunity to redeem their shares of Common Stock 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 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 held
by it, him or her. The Sponsor and each Insider hereby further waives, with respect to any shares of Common Stock held by it, him
or her, if any, whether acquired now or hereafter, any redemption rights it, he or she may have in connection with the consummation
of a Business Combination or amendments to the Charter prior thereto, including, without limitation, any such rights available
in the context of a stockholder vote to approve such Business Combination or a stockholder vote to approve an amendment to the
Charter to modify (i) (A) the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the
Company has not consummated a Business Combination within the time period set forth in the Charter or (B) any other provisions
relating to stockholders' rights or pre-initial Business Combination activity or (ii) in the context of a tender offer made by
the Company to purchase shares of Common Stock (although the Sponsor, 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 the time period set forth in the Charter).


 


3. During the period
commencing on the date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider 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 (the “Exchange Act”), and the rules and regulations of the Commission
promulgated thereunder, with respect to any Units, shares of Capital Stock, Warrants or any securities convertible into, or exercisable,
or exchangeable for, shares of Capital 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 Capital Stock, Warrants
or any securities convertible into, or exercisable, or exchangeable for, shares of Capital 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). Each of the Insiders 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 or paragraph 7 below, 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 the release or waiver is effected solely
to permit a transfer not for consideration and 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.


 


4. In the event of
the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination within the
time period set forth in the Charter, the Sponsor (which for purposes of clarification shall not extend to any other shareholders,
members or managers of the Sponsor ) (the “Indemnitor”) 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)
to which the Company may become subject as a result of any claim by (i) any third party for services rendered (other than the Company’s
independent public accountants) or products sold to the Company or (ii) any prospective target business with which the Company
has entered into a written letter of intent, confidentiality or other similar agreement or Business Combination agreement (a “Target”); provided, however,
that such indemnification of the Company by the Indemnitor shall (x) apply only to the extent necessary to ensure that such claims
by a third party or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.25 per Offering
Share and (ii) the actual amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account,
if less than $10.25 per Offering Share is then held in the Trust Account due to reductions in the value of the trust assets, less
interest earned on the Trust Account which may be withdrawn to pay taxes, (y) not apply to any claims by a third party or a Target
which executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable)
and (z) not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including
liabilities under the Securities Act of 1933, as amended. The Indemnitor 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 Indemnitor, the Indemnitor 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 up to an additional 1,500,000 Units in full within 45
days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a
number of Founder Shares in the aggregate equal to 375,000 multiplied by a fraction, (i) the numerator of which is 1,500,000 minus
the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of
which is 1,500,000. The Sponsor will be required to forfeit only that number of Founder Shares as is necessary so that the Initial
Stockholders will own an aggregate of 20.0% of the Company’s issued and outstanding shares of Capital Stock after the Public
Offering.


 


6. (a) Each of the officers and
directors of the Company hereby agrees not to participate in the formation of, or become an officer or director of, any other special
purpose acquisition company with a class of securities registered under the Exchange Act until the Company has entered into a definitive
agreement regarding an initial Business Combination or until the Company has liquidated the Trust Account.


 


(b) The Sponsor and each Insider
hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach
by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 6(a), 7(a), 7(b), and 9, as applicable,
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) The Sponsor 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 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 Common Stock for cash, securities or other property (the “Founder Shares Lock-up Period”).


 


(b) The Sponsor and each Insider
agrees that it, he or she shall not Transfer any Private Placement Warrants or shares of 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 Lock-up Period”,
together with the Founder Shares Lock-up Period, the “Lock-up Periods”).


 


(c) Notwithstanding the provisions
set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and shares of Common Stock issued
or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares that are held by the Sponsor,
any Insider or any of their permitted transferees (that have complied with this paragraph 7(c)), are permitted (a) to the Company’s
officers or directors, any affiliate or family member of any of the Company’s officers or directors or any affiliate of the
Sponsor or to any member(s) of the Sponsor; (b) in the case of an individual, by gift to a member of such individual’s immediate
family or to a trust, the beneficiary of which is a member of such individual’s immediate family, an affiliate of such individual
or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of
such individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers
made in connection with the consummation of an initial Business Combination at prices no greater than the price at which the shares
or warrants were originally purchased; (f) 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 common stock for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination; provided, however,
that in the case of clauses (a) through (e) or (g), these permitted transferees must enter into a written agreement with the Company
agreeing to be bound by the transfer restrictions herein.

modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument

conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto
(i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall
