Certain of the Reporting Persons acquired the shares of Common Stock from the Issuer in various transactions, including the OTR Merger (as defined below) and one or more private placement transactions, including those described below, all as previously disclosed. On May 19, 2022, the Issuer 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 (as amended, the “Business Combination Agreement”) by and among the Issuer, 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”). As contemplated in the Business Combination Agreement, (i) Comera Merger Sub merged with and into Comera, with Comera surviving such merger as a direct wholly-owned subsidiary of the Issuer (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 the Issuer (the “OTR Merger”) (collectively with the other transactions described in the Business Combination Agreement, the “Business Combination”). Upon the closing of the Business Combination, by virtue of the Comera Merger, all shares of Comera common stock, par value $0.001 per share (“Comera Common Stock”), issued and outstanding were canceled and converted into the right to receive shares of the Issuer’s Common Stock. Certain of the Reporting Persons were former holders of Comera Common Stock, and immediately after the closing of, and giving effect to the Business Combination and issuance of Common Stock in connection therewith, became the beneficial owner of Common Stock.

On January 2, 2023, the Issuer entered into a securities purchase agreement (the “January 2023 Purchase Agreement”) with certain purchasers, including certain of the Reporting Persons, pursuant to which the Issuer agreed to sell to the purchasers (the “January 2023 Purchasers”) in a private placement shares of Common Stock (the “January 2023 Shares”) and accompanying warrants (the “January 2023 Warrants”) to purchase shares of Common Stock (the “January 2023 Warrant Shares”). Pursuant to the registration rights agreement entered into with the January 2023 Purchasers on January 4, 2023 (the “January 2023 Registration Rights Agreement”), the Issuer filed a registration statement with the Securities and Exchange Commission (the “SEC”) covering resales of the January 2023 Shares and the January 2023 Warrant Shares by the January 2023 Purchasers on February 3, 2023, which was declared effective on February 10, 2023.

On July 31, 2023, the Issuer entered into a securities purchase agreement (the “July 2023 Purchase Agreement”) with certain purchasers, including certain of the Reporting Persons, pursuant to which the Issuer agreed to issue and sell to the purchasers (the “July 2023 Purchasers”) in a private placement (the “July 2023 Private Placement”) shares of Common Stock and accompanying warrants (the “July 2023 Warrants”) to purchase shares of Common Stock (the “July 2023 Warrant Shares”).

On December 29, 2023, the Issuer entered into a securities purchase agreement (the “December 2023 Purchase Agreement”) with certain persons, including each of the Reporting Persons, pursuant to which the Issuer agreed to issue and sell in a private placement (the “December 2023 Private Placement”) $1,500,000 in aggregate principal amount of 12.0% Senior Secured Convertible Notes due 2024 (collectively, the “December 2023 Notes”) and accompanying warrants (the “December 2023 Warrants”) to purchase up to an aggregate number of shares (the “December 2023 Warrant Shares”) of the Issuer’s Common Stock equal to 200% of the number of the shares of Common Stock (the “Note Shares”) issuable upon conversion of the December 2023 Notes immediately following the closing of the December 2023 Private Placement. Pursuant to the December 2023 Purchase Agreement, as long as any person owns any securities purchased thereunder, and upon written request by holders of December 2023 Notes representing at least a majority of the aggregate principal amount of the December 2023 Notes then outstanding, the Issuer has agreed to register the resale of all of the Note Shares and December 2023 Warrant Shares with the SEC as soon as reasonably practicable.

Pursuant to the December 2023 Purchase Agreement, the holders of the securities purchased thereunder, including the Reporting Persons, have a right, for one year from the date of execution of the December 2023 Purchase Agreement, to participate in up to 50% in the aggregate offering amount of any equity securities that the Issuer may issue or sell, subject to certain limited exceptions.

The December 2023 Purchase Agreement states that the purchase price of the Share Purchase will be cash consideration per share of Common Stock equal to the greater of: (i) $0.0825 per share of Common Stock and (ii) an amount per share of Common Stock equal to 1.5 times the closing price of the Issuer’s Common Stock on the date immediately preceding the execution of a definitive agreement to effect the Share Purchase. The Share Purchase process may be initiated upon the written notice of holders of December 2023 Notes representing at least two-thirds of the aggregate principal amount of the December 2023 Notes then outstanding.

The completion of the Share Purchase will be subject to a number of conditions, including, among other things, satisfactory completion of its due diligence review of the Issuer, the negotiation and execution of a definitive merger agreement containing representations, warranties, covenants, closing conditions and other terms and provisions as are appropriate for a transaction of this nature and which are mutually agreed upon by the parties, and the receipt of all necessary governmental and regulatory approvals and all third party consents and approvals as are required in connection with the Share Purchase.

In connection with the Share Purchase right, until the later of December 29, 2024 and the payment in full in cash of all obligations in respect of the December 2023 Purchase Agreement and the securities issued thereunder, the Issuer has agreed to deal exclusively with the holders of the securities acquired under the December 2023 Purchase Agreement, such that neither the Issuer nor any of its representatives will, directly or indirectly, solicit, encourage or initiate any offer or proposal from, or engage in any discussions with, or provide any information to, any corporation, partnership, person or other entity or group concerning the sale of the Issuer or any of its securities or assets or any merger, consolidation, liquidation, restructuring, recapitalization or similar transaction involving the Issuer, except with respect to the sale of assets in the ordinary course of business consistent with past practice.

The foregoing descriptions in this Item 3 do not purport to be complete and are qualified in their entirety by reference to the January 2023 Warrant, the January 2023 Purchase Agreement, the January 2023 Registration Rights Agreement, the July 2023 Warrant, the July 2023 Purchase Agreement, the July 2023 Registration Rights Agreement, the December 2023 Purchase Agreement, the December 2023 Note and the December 2023 Warrant, copies or forms of which are included as Exhibits 99.2, 99.3, 99.4, 99.5, 99.6, 99.7, 99.8, 99.9 and 99.10, respectively, and incorporated herein by reference in their entirety.

Item 4. Purpose of Transaction.

The Reporting Persons that purchased the Preferred Shares and the securities in the December 2023 Private Placement did so with the intention of acquiring all outstanding shares of the Issuer’s Common Stock not then held by such holders and the other Reporting Persons.
