PROMISSORY NOTE

Principal Amount:  Up to $500,000.00 Dated as of March 1, 2022

OTR Acquisition Corp., a Delaware corporation (“Maker”), promises to pay to the order of OTR Acquisition Sponsor LLC (“Payee”), the principal sum of up to Five Hundred Thousand Dollars ($500,000) in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by Maker to such account as Payee may from time to time designate by written notice in accordance with the provisions of this Note.

1.Principal. The principal balance of this Note shall be payable on the earliest to occur of (i) the date on which Maker consummates its initial business combination and (ii) the date that the winding up of Maker is effective (such date, the “Maturity Date”). The principal balance may be prepaid at any time.

2.Interest. No interest shall accrue on the unpaid principal balance of this Note.

3.Drawdown Requests. The principal of this Note may be drawn down from time to time prior to the Maturity Date upon request from Maker to Payee (each, a “Drawdown Request”). Payee shall fund each Drawdown Request within five (5) business days after receipt of such Drawdown Request; provided, however, that Payee shall fund One Hundred Thousand Dollars ($100,000) upon execution of this Note (the “Initial Drawdown”); provided, further, that the maximum amount of drawdowns collectively under this Note is Five Hundred Thousand Dollars ($500,000). Once an amount is drawn down under this Note, it shall not be available for future Drawdown Requests even if prepaid. No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.

4.Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.

5.Conversion.

(a)           At Payee’s option, on the Maturity Date in the event Maker consummates its initial business combination, Payee may elect to convert all or any portion of the principal outstanding under this Note into that number of warrants (“Working Capital Warrants”) equal to: (i) the portion of the principal amount of this Note being converted pursuant to this Section 5, divided by (ii) $1.00, rounded up to the nearest whole number. Each Working Capital Warrant shall have the same terms and conditions as the warrants issued by Maker pursuant to a private placement to OTR Acquisition Sponsor LLC (the “Private Placement”), as described in the prospectus (the “Prospectus”) for Maker’s initial public offering (the “IPO”) dated November 17, 2020 and filed with the U.S. Securities and Exchange Commission, including the transfer restrictions applicable thereto. The Working Capital Warrants and the shares of Class A common stock underlying such warrants, and any other equity security of Maker issued or issuable with respect to the foregoing by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or reorganization, shall be entitled to the registration rights set forth in that certain registration rights agreement between Maker and the parties thereto, dated as of November 17, 2020.

(b)           Upon any complete or partial conversion of the principal amount of this Note, (i) such principal amount shall be so converted and such converted portion of this Note shall become fully paid and satisfied, (ii) Payee shall surrender and deliver this Note, duly endorsed, to Maker or such other address which Maker shall designate against delivery of the Working Capital Warrants, (iii) Maker shall promptly deliver a new duly executed Note to Payee in the principal amount that remains outstanding, if any, after any such conversion and (iv) in exchange for all or any portion of the surrendered Note, Maker shall, within five (5) business days following receipt by Maker of Payee’s election to convert this Note pursuant to this Section 5, deliver to Payee the Working Capital Warrants, which shall bear such legends as are required in the opinion of counsel to Maker or by any other agreement between Maker and Payee and applicable state and federal securities laws.

(c)           Payee shall pay any and all issue and other taxes that may be payable with respect to any issue or delivery of the Working Capital Warrants upon conversion of this Note pursuant hereto; provided, however, that Payee shall not be obligated to pay any transfer taxes resulting from any transfer requested by Payee in connection with any such conversion.

(d)           The Working Capital Warrants shall not be issued upon conversion of this Note unless such issuance and such conversion comply with all applicable provisions of law. No fractional warrants shall be issued upon conversion of this Note. For the avoidance of doubt, in the event that all principal on this Note has been paid in full on or prior to the Maturity Date, then Payee shall not be entitled to convert any portion of this Note into Working Capital Warrants. Upon conversion of this Note in full, this Note shall be cancelled and void without further action of Maker or Payee, and Maker shall be forever released from all its obligations and liabilities under this Note.

6.Events of Default. The following shall constitute an event of default (“Event of Default”):

(a)           Failure to Make Required Payments. Failure by Maker to pay the principal amount due pursuant to this Note within five (5) business days of the date specified in Section 1 above.

(b)           Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by Maker in furtherance of any of the foregoing.

(c)           Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days.
