Introductory Note

On May 19, 2022, Comera Life Sciences Holdings, Inc., a Delaware corporation (“Holdco”), consummated the acquisition of all of the issued and outstanding shares of OTR Acquisition Corp., a Delaware corporation (“OTR”) and Comera Life Sciences, Inc., a Delaware corporation (“Comera”), in accordance with that certain Business Combination Agreement, dated as of January 31, 2022 (as amended, the “Business Combination Agreement”), by and among Holdco, OTR, Comera, CLS Sub Merger 1 Corp., a Delaware corporation, (“Comera Merger Sub”), and CLS Sub Merger 2 Corp., a Delaware corporation (“OTR Merger Sub”).

On May 19, 2022 (the “Closing Date”), as contemplated in the Business Combination Agreement and described in the section titled “Proposal No. 1 — The Business Combination Proposal” of the definitive proxy statement/prospectus, (the “Proxy Statement/Prospectus”), filed by OTR with the Securities and Exchange Commission (the “SEC”) on April 15, 2022: (i) Comera Merger Sub merged with and into Comera, with Comera surviving such merger as a direct wholly-owned subsidiary of Holdco (the “Comera Merger”) and (ii) OTR Merger Sub merged with and into OTR, with OTR surviving such merger as a direct wholly-owned subsidiary of Holdco (the “OTR Merger”) (collectively with the other transactions described in the Business Combination Agreement, the “Business Combination”). Upon the closing of the Business Combination (the “Closing”), by virtue of the Comera Merger, all shares of Comera Common Stock issued and outstanding immediately prior to the Closing (including shares of Comera Common Stock issued upon conversion of Comera preferred stock immediately prior to the Closing) were canceled and converted into the right to receive shares of Holdco common stock, par value $0.0001 per share (“Holdco Common Stock”), all Comera vested in-the-money stock non-qualified stock options outstanding were canceled and converted into the right to receive shares of Holdco Common Stock and all outstanding Comera unvested stock options and Comera vested incentive stock options and vested out-of-the-money options were converted into options to purchase shares of Holdco Common Stock.

At the time of the OTR Merger, by virtue of the OTR Merger and without any action on the part of OTR, Holdco, OTR Merger Sub or the holders of any of the following securities: (i) immediately prior to the OTR Merger, all shares of OTR Class B Common Stock, , par value $0.0001, were converted (“OTR Class B Conversion”) into shares of OTR Class A Common Stock, par value $0.0001 (“OTR Class A Common Stock”); (ii) immediately prior to the OTR Merger Effective Time, the shares of OTR Class A Common Stock and the warrants to purchase shares of OTR Class A Common Stock as contemplated under the Warrant Agreement (as defined below), with each whole warrant exercisable for one share of OTR Class A Common Stock at an exercise price of $11.50 per whole share (the “OTR Warrants”) comprising each issued and outstanding OTR Unit immediately prior to the OTR Merger was automatically separated (the “Unit Separation”) and the holder thereof was deemed to hold one share of OTR Class A Common Stock and one-half of one OTR Warrant, (iii) following the OTR Class B Conversion and Unit Separation, each share of OTR Class A Common Stock issued and outstanding immediately prior to the OTR Merger Effective Time was automatically converted into and become the right to receive one (1) share of Holdco Common Stock and all OTR Warrants were converted into warrants to purchase shares of Holdco Common Stock, subject to the same terms and conditions as were applicable to the OTR Warrants and (iv) all shares of OTR common stock held in the treasury of OTR were canceled without any conversion thereof and no payment or distribution will be made with respect thereto.

Capitalized terms not otherwise defined have the meaning set forth in the Business Combination Agreement. The description of the Business Combination Agreement and related transactions (including, without limitation, the OTR Merger and the Comera Merger) in this Current Report on Form 8-K does not purport to be complete and is subject to, and qualified in its entirety by reference to, the full text of the Business Combination Agreement, which is attached as Exhibit 2.1 to OTR’s Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on January 31, 2022 and is incorporated herein by reference.

Item 1.01.

Entry into a Material Definitive Agreement.

The information set forth in the Introductory Note of this Current Report on Form 8-K is incorporated herein by reference.

Upon the completion of the Business Combination, OTR entered into that certain Warrant Assumption Agreement (the “Warrant Assumption Agreement”) by and among OTR, Holdco and Continental Stock Transfer & Trust Company, a New York corporation (“Continental”). Pursuant to the Warrant Assumption Agreement, Holdco assumed all of OTR’s rights and obligations under the Warrant Agreement, dated as of November 17, 2020 by and between OTR and Continental (the “Warrant Agreement”), and each OTR Warrant entitling the holder thereof to acquire one share of OTR Class A Common Stock was converted into a warrant to acquire one share of Holdco Common Stock, subject to the same terms and conditions as were applicable to the OTR Warrant.

On May 19, 2022, OTR, Holdco, and certain existing stockholders of OTR and Comera (collectively, the “Reg Rights Holders”) entered into a Registration Rights Agreement (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, Holdco will be obligated to file a registration statement to register the resale of 5,917,757 warrants convertible into shares, and approximately 19,169,698 shares (including 5,917,757 shares issuable upon exercise of the warrants), of Holdco Common Stock held by certain Reg Rights Holders. In addition, subject to certain requirements and customary conditions, including with regard to the number of demand rights that may be exercised, certain Reg Rights Holders may demand at any time or from time to time, to sell all or any portion of their registrable securities in an underwritten offering so long as the total offering price is reasonably expected to exceed $30 million. The Registration Rights and Lock-Up Agreement also provides certain Reg Rights Holders with “piggy-back” registration rights, subject to certain requirements and customary conditions.

Subject to certain exceptions, the Registration Rights and Lock-Up Agreement further provides for the Holdco Common Stock held by the Reg Rights Holders to be locked-up until the earlier of (i) one year following the Closing and (ii) the date on which the sale price of the Holdco Common Stock equals or exceeds $12.00 per share for any 20 trading days within any 30-day trading period commencing 150 days after the Closing.
