ORGANIZATION AND DESCRIPTION OF BUSINESS OPERATIONS | NOTE 1 ─ ORGANIZATION AND DESCRIPTION OF BUSINESS OPERATIONS OTR Acquisition Corp . The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination, however, the Company intends to concentrate its efforts to initially focus on identifying businesses within North America. As of March 31, 2022, the Company had not yet commenced any operations. All activity for the period from July 23, 2020 (inception) through March 31, 2022 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below, identifying a target company for a Business Combination and negotiating and seeking to consummate a Business Combination. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company’s sponsor is OTR Acquisition Sponsor LLC, a Delaware limited liability company (the “Sponsor”). The registration statement on Form S-1 for the Company’s Initial Public Offering was declared effective on November 17, 2020. On November 19, 2020, the Company consummated its Initial Public Offering of 10,000,000 units (the “Units” and, with respect to the Class A common stock included in the Units offered in the Initial Public Offering, the “Public Shares”) at $10.00 per Unit, generating gross proceeds of $100.0 million. The underwriters were granted a 45-day option from the date of the final prospectus relating to the Initial Public Offering to purchase up to 1,500,000 additional Units to cover over-allotments, if any, at $10.00 per Unit. The underwriters’ over-allotment option was partially exercised, resulting in the purchase of an additional 447,350 Units, resulting into incremental gross proceeds of approximately $4.5 million. On December 21, 2020, the underwriters waived their right to exercise the remaining over-allotment option. Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 5,650,000 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) to the Sponsor, each exercisable to purchase one share of Class A common stock at $11.50 per share, at a price of $1.00 per Private Placement Warrant, generating gross proceeds to the Company of $5.7 million. In connection with the partial exercise of the underwriters’ over-allotment option, the Sponsor purchased an additional 167,757 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, generating additional gross proceeds of $0.17 million (see Note 4). Transaction costs amounted to $7.1 million consisting of $1.8 million of the fair value of the shares issued to Maxim Group LLC for acting as the representative of the several underwriters in connection with the Initial Public Offering, $1.3 million in cash underwriting fees, $3.4 million of deferred underwriting fees and $0.55 million of other offering costs. In addition, as of March 31, 2022 cash of $83,673 was held outside of the Trust Account (as defined below) and is available for the payment of offering costs and for working capital purposes. Upon the closing of the Initial Public Offering and the Private Placement (including the additional Units and additional Private Placement Warrants sold in connection with the partial exercise of the underwriters’ over-allotment option), $107.1 million ($10.25 per Unit) of the net proceeds of the sale of the Units in the Initial Public Offering and the Private Placement were placed in a trust account (“Trust Account”) located in the United States at JP Morgan Chase Bank, N.A. with Continental Stock Transfer & Trust Company acting as trustee. The funds in the Trust Account can only be invested in U.S. “government securities,” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”) having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of: (i) the completion of an initial Business Combination and (ii) the distribution of the Trust Account as described below. NOTE 1 ─ ORGANIZATION AND DESCRIPTION OF BUSINESS OPERATIONS (Continued) The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete a Business Combination with one or more operating businesses or assets that together have an aggregate fair market value equal to at least 80% of the net assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of the Company’s signing a definitive agreement in connection with a Business Combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires an interest in the target business or assets sufficient for it not to be required to register as an investment company under the Investment Company Act. The Company will provide its holders of the outstanding Public Shares (the “public stockholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of its initial Business Combination either (i) in connection with a stockholder meeting called to approve the initial Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of its initial Business Combination or conduct a tender offer will be made by the Company. The public stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.25 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). There will be no redemption rights upon the completion of an initial Business Combination with respect to the Company’s warrants. The Public Shares subject to redemption will be recorded at redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board Accounting Standard Codification, or FASB ASC Topic 480, “Distinguishing Liabilities from Equity.” The Company will only proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 either prior to or upon such consummation of a Business Combination and, if the Company seeks stockholder approval, a majority of the shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by applicable law or stock exchange rules and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by applicable law or stock exchange rules, or the Company decides to obtain stockholder approval for business or other reasons, the Company will offer to redeem the Public Shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5), and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or do not vote at all. Notwithstanding the above, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Amended Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), will be restricted from redeeming its shares with respect to more than an aggregate of 20% or more of the Public Shares, without the prior consent of the Company. NOTE 1 ─ ORGANIZATION AND DESCRIPTION OF BUSINESS OPERATIONS (Continued) The Sponsor has agreed (a) to waive its redemption rights with respect to its Founder Shares and Public Shares held by it in connection with the completion of a Business Combination and (b) not to propose an amendment to the Certificate of Incorporation (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of its Public Shares if the Company does not complete a Business Combination or (ii) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity, unless the Company provides the public stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment. The Company will have until 18 months from the closing of the Initial Public Offering, or May 19, 2022, to complete a Business Combination (the “Combination Period”). If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten The Sponsor has agreed to waive its liquidation rights with respect to the Founder Shares (as defined in Note 6) if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor acquires Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than $10.25 per share. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (1) $10.25 per Public Share and (2) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account nor will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses and other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. Business Combination On January 31, 2022, Comera Life Sciences Holdings, Inc., a Delaware corporation (“Holdco”), CLS Sub Merger 1 Corp., a Delaware corporation and newly formed, wholly-owned subsidiary of Holdco (“Comera Merger Sub”), CLS Sub Merger 2 Corp., a Delaware corporation and newly formed, wholly-owned subsidiary of Holdco (“OTR Merger Sub”), the Company and Comera Life Sciences, Inc., a Delaware corporation (“Comera”), entered into a Business Combination Agreement (as amended from time to time, the “Business Combination Agreement”). NOTE 1 ─ ORGANIZATION AND DESCRIPTION OF BUSINESS OPERATIONS (Continued) Business Combination (Continued) If the Business Combination Agreement and the transactions contemplated thereby provide that, subject to adoption and approval by the Company’s stockholders, and the proposed Business Combination is subsequently completed, (i) Comera Merger Sub be 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 will be merged with and into the Company, with the Company 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 “Proposed Business Combination”). For additional information regarding the Business Combination and the Merger Agreement and related agreements, see the Current Reports on Form 8-K filed by the Company with the SEC on January 31, 2022 and on February 4, 2022. On April 14, 2022, the SEC declared effective Comera’s registration statement on Form S-4 (File No. 333-263377) (the “S-4 Registration Statement”) filed with the SEC in connection with the Proposed Business Combination and, on April 15, 2022, the Company commenced mailing the definitive proxy statement/prospectus relating to the special meeting in lieu of the 2022 annual meeting of the Company’s stockholders (the “Special Meeting”). The Company held the Special Meeting in a virtual format on May 10, 2022, at 2:00 p.m., Eastern time. At the Special Meeting the Company’s stockholders adopted the Business Combination Agreement, thereby approving the Proposed Business Combination and approved the other proposals described in the S-4 Registration Statement. As of May 11, 2022, holders of an aggregate of 10,279,363 shares of Class A common stock had exercised their right to redeem their shares in connection with the Special Meeting. Subsequently, the Company has been made aware that certain holders of Class A common stock may request to change their election to have their shares redeemed, which the Company may allow. There can be no assurance, however, that such holders will request to change their election to redeem their shares or that the final number of shares redeemed will decrease. Upon the closing of the Proposed Business Combination (the “Closing”), which is expected to occur on or before May 19, 2022, subject to satisfaction or waiver of all necessary closing conditions set forth in the Business Combination Agreement, 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) will be canceled and converted into the right to receive shares of Holdco common stock, all Comera vested in-the-money stock options outstanding will be canceled and converted into the right to receive shares of Holdco common stock and all outstanding Comera unvested stock options and Comera vested out-of-the-money options will be converted into options to purchase shares of Holdco common stock. The aggregate transaction consideration to be paid in the Comera Merger will be the number of shares of Holdco common stock equal to $126 million divided by $10.00. The aggregate transaction consideration will be allocated among the holders of shares of Comera common stock (including Comera common stock issued upon the conversion of Comera preferred stock) and holders of Comera in-the-money stock options. In addition, at the Closing, Holdco will place 3,150,000 shares of Holdco Common Stock (the “Earn-Out Shares”) into escrow. If, at any time during the period beginning on the Closing Date and expiring at the close of business on the second anniversary of the Closing Date, the volume-weighted average price of Holdco Common Stock is equal to or greater than $12.50 for any 20 trading days within a period of 30 consecutive trading days (the “Earn-Out Trigger”), then within 10 business days following the achievement of the Earn-Out Trigger, the Earn-Out Shares will be released to the holders of Comera Common Stock and holders of Comera Vested In-the-Money Options on a pro rata basis. Immediately prior to the OTR Merger Effective Time, all shares of the Company’s Class B Common Stock will be converted into shares of the Company’s Class A Common Stock. Upon the Closing, by virtue of the OTR Merger, all shares of the Company’s Class A common stock of issued and outstanding immediately prior to the Closing will be converted on a one-to-one basis into the right to receive shares of Holdco common stock and all the Company’s warrants of outstanding will be converted into warrants to purchase shares of Holdco common stock. |
