Item 4 of the Schedule 13D is amended and supplemented as follows: Agreement and Plan of Merger On December 23, 2024, the Issuer entered into an Agreement and Plan of Merger (the "Merger Agreement") with Parent and NH Holdings Acquisition 2025, Inc., a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"), pursuant to which, among other things and on the terms and subject to the conditions set forth therein, Merger Sub will merge with and into the Issuer (the "Merger"), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent. Parent and Merger Sub are affiliated with the NEA Venture Funds. In connection with the execution of the Merger Agreement, certain stockholders of the Issuer (the "Rollover Holders") have entered into rollover agreements (the "Rollover Agreements") with Ultimate Parent, Parent and Merger Sub, pursuant to which, among other things and on the terms and subject to the conditions set forth therein, the Rollover Holders have agreed to contribute all of their shares of Common Stock, Series A Convertible Perpetual Preferred Stock of the Issuer, par value $0.0001 per share (the "Company Series A Preferred Stock"), and/or Series B Convertible Perpetual Preferred Stock of the Issuer, par value $0.0001 per share (the "Company Series B Preferred Stock" and, together with the Company Series A Preferred Stock, the "Company Preferred Stock"), to Ultimate Parent immediately prior to the effective time of the Merger (the "Effective Time") in exchange for the issuance to the Rollover Holders of limited partnership interests in Ultimate Parent. The Rollover Agreements are further described below. The Merger Agreement provides that, at the Effective Time, each share of Common Stock that is issued and outstanding immediately prior to the Effective Time (other than shares owned immediately prior to the Effective Time by the Issuer, Ultimate Parent, Parent, Merger Sub or any of their respective subsidiaries (including shares contributed to Ultimate Parent prior to the Effective Time pursuant to the Rollover Agreements or other similar agreements), which will be canceled for no consideration, and Dissenting Shares (as defined below) will be converted into the right to receive $7.33 in cash, without interest and less any applicable withholding taxes. Shares of Common Stock with respect to which a demand for appraisal has been validly made (and not forfeited or withdrawn) in accordance with Delaware law ("Dissenting Shares") will be entitled to receive payment of the appraised value of such shares as provided by Delaware law. The board of directors of the Issuer (the "Company Board"), acting upon the unanimous recommendation of a special committee of the Company Board (the "Special Committee") composed entirely of independent and disinterested directors and advised by its own independent legal and financial advisors, unanimously approved the Merger Agreement and the transactions contemplated thereby, including the Merger, and resolved to recommend that the stockholders of the Issuer approve and adopt the Merger Agreement. If the Merger is consummated, the Common Stock will be delisted from the New York Stock Exchange and deregistered under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Treatment of Equity Awards The Merger Agreement provides for the following treatment of outstanding Issuer equity awards at the Effective Time: (A) Each option to purchase shares of Common Stock, whether vested or unvested, that has a per share exercise price less than the Merger Consideration will be, at the election of Parent, either (a) assumed by Parent or (b) converted into the right to receive an amount in cash equal to the product of (i) the excess of the Merger Consideration over the applicable per share exercise price of such option, multiplied by (ii) the total number of shares of Common Stock subject to such option immediately prior to the Effective Time. (B) Each option to purchase shares of Common Stock, whether vested or unvested, that has a per share exercise price equal to or greater than the Merger Consideration will be, at the election of Parent, either (a) assumed by Parent or (b) canceled for no consideration. (C) Each restricted stock unit of the Issuer with respect to shares of Common Stock that is subject solely to service-based vesting requirements (and not performance-based vesting requirements) (each, a "Company RSU") will be, at the election of the holder, either (a) assumed by Parent and adjusted into a restricted stock unit of Parent (each, a "Parent RSU") with respect to a number of shares of common stock of Parent equal to the number of shares of Common Stock subject to such Company RSU and having the same vesting and other terms and conditions as such Company RSU or (b) assumed by Parent and adjusted into a Parent RSU with respect to a number of shares of common stock of Parent equal to the number of shares of Common Stock subject to such Company RSU and having the same vesting and other terms and conditions as such Company RSU, except that the vesting of such Parent RSU will also be contingent upon the occurrence of a change of control or an initial public offering of the Issuer within a specified period after the date on which the Merger occurs ("Double-Trigger Parent RSUs"). Holders of Company RSUs who elect to receive Double-Trigger Parent RSUs will also receive an additional grant of Parent RSUs with respect to a number of shares of common stock of Parent that is equal to 20% of the number of shares of Common Stock subject to the Company RSUs held by such holder immediately prior to the Effective Time, which will be subject to certain additional time-based and performance-based vesting requirements. (D) Each restricted stock unit of the Issuer with respect to shares of Common Stock that is subject to performance-based vesting requirements will be canceled for no consideration. Conditions to the Merger The completion of the Merger is subject to the fulfillment or waiver of certain customary mutual closing conditions, including (a) the adoption of the Merger Agreement by the affirmative vote of the holders of a majority of the voting power of the outstanding shares of Common Stock and Company Preferred Stock (voting on an as-converted basis), voting together as a single class, that are entitled to vote thereon (the "Company Stockholder Approval"), (b) the absence of any law or order prohibiting, enjoining or making illegal the consummation of the Merger and (c) all specified regulatory filings and approvals required in connection with the transactions contemplated by the Merger Agreement having been made or received, as applicable. The obligation of each party to consummate the Merger is also subject to the fulfillment or waiver of certain customary unilateral closing conditions, including the other party's (or parties') representations and warranties being true and correct (subject to certain customary materiality qualifiers) and the other party (or parties) having performed in all material respects its (or their) obligations under the Merger Agreement. The obligation of each of Parent and Merger Sub to consummate the Merger is additionally conditioned upon there not having been imposed any Burdensome Condition (as defined in the Merger Agreement) in connection with the receipt of the regulatory approvals required in connection with the transactions contemplated by the Merger Agreement. The consummation of the Merger is not subject to any financing condition. Go-Shop; No-Shop During the period beginning on the date of the Merger Agreement and continuing until 12:01 a.m. New York City time on January 23, 2025 (the "No-Shop Start Date"), the Issuer is permitted to solicit, initiate and facilitate alternative acquisition proposals from third parties and provide non-public information to, and engage in discussions and negotiations with, third parties with respect to alternative acquisition proposals. After the No-Shop Start Date, the Issuer will become subject to customary "no-shop" restrictions on its ability to solicit alternative acquisition proposals from third parties and to provide non-public information to, and engage in discussions or negotiations with, third parties regarding alternative acquisition proposals, except that, until the receipt of the Company Stockholder Approval, the Issuer may continue to engage in the aforementioned activities with any third party that made an alternative acquisition proposal to acquire 50% or more of the assets or total voting power of the equity securities of the Issuer prior to the No-Shop Start Date that the Special Committee (or the Company Board, acting upon the recommendation of the Special Committee) has determined in good faith constitutes or would reasonably be expected to result in a Superior Proposal (as defined in the Merger Agreement) and that has not terminated or been withdrawn (each, an "Excluded Party"). The "no-shop" restrictions are additionally subject to a customary "fiduciary out" provision that allows the Issuer, under certain specified circumstances, to provide non-public information to, and engage in discussions or negotiations with, third parties with respect to an alternative acquisition proposal if the Special Committee (or the Company Board, acting upon the recommendation of the Special Committee) determines in good faith (after consultation with its financial advisor and outside legal counsel) that such alternative acquisition proposal constitutes or would reasonably be expected to result in a Superior Proposal and the failure to take such actions would be inconsistent with its fiduciary duties pursuant to applicable law. In the event that an Intervening Event (as defined in the Merger Agreement) occurs or the Issuer receives a bona fide written alternative acquisition proposal that did not result from a breach of the "no-shop" restrictions in the Merger Agreement and that the Special Committee (or the Company Board, acting upon the recommendation of the Special Committee) determines in good faith (after consultation with its financial advisor and outside legal counsel) constitutes a Superior Proposal, then, on the terms and subject to the conditions set forth in the Merger Agreement, the Special Committee and/or the Company Board may, in certain circumstances prior to the receipt of the Company Stockholder Approval and subject to certain notice and "matching" rights of Parent, change its recommendation that the Issuer's stockholders adopt the Merger Agreement. Termination and Fees The Merger Agreement contains customary termination rights for the Issuer (acting with the prior authorization of the Special Committee) and Parent, including, among other circumstances, (a) by either party in the event that the consummation of the Merger does not occur on or before September 23, 2025, subject to up to two consecutive three-month extensions if, on such date (or the extension thereof), all of the closing conditions in the Merger Agreement except for those relating to regulatory approvals have been satisfied or waived, (b) by either party in the event that the Company Stockholder Approval is not obtained at a meeting of the Issuer's stockholders at which a vote on the adoption of the Merger Agreement was held, (c) by Parent, prior to the receipt of the Company Stockholder Approval, in the event of an adverse change of the Special Committee's or Company Board's recommendation that the Issuer's stockholders adopt the Merger Agreement, (d) by the Issuer, prior to the receipt of the Company Stockholder Approval, in order to enter into a definitive acquisition agreement with respect to a Superior Proposal and (e) by the Issuer, in the event that Parent has failed to consummate the Merger when required under the Merger Agreement after the Issuer has confirmed in writing that it is ready, willing and able to consummate the Merger. If the Merger Agreement is terminated in certain specified circumstances, the Issuer will be required to pay a termination fee to Parent. If the termination fee becomes payable as a result of the Issuer terminating the Merger Agreement prior to the receipt of the Company Stockholder Approval in order to enter into a definitive acquisition agreement with respect to a Superior Proposal by an Excluded Party, or as a result of Parent terminating the Merger Agreement due to an adverse change of the Special Committee's or Company Board's recommendation that the Issuer's stockholders adopt the Merger Agreement in connection with an alternative acquisition proposal made by an Excluded Party, then the amount of the termination fee will be $1,500,000. If the termination fee becomes payable in other circumstances, then the amount of the termination fee will be $3,600,000. Other Terms of the Merger Agreement The Issuer has made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants to use commercially reasonable efforts to conduct its business in the ordinary course during the period between the date of the Merger Agreement and the Effective Time. Each of Parent, Merger Sub and the Issuer has agreed to use reasonable best efforts to take all actions necessary, proper or advisable under applicable law to consummate the Merger, including cooperating to obtain the regulatory approvals necessary to complete the Merger, subject to certain limitations set forth in the Merger Agreement (including that none of Parent, Merger Sub or any of their affiliates are obligated to agree to or otherwise become subject to any Burdensome Condition). The foregoing description of the Merger Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which is attached to this Amendment No. 8 as Exhibit 3and is incorporated by reference herein. Rollover Agreements In connection with the execution of the Merger Agreement, on December 23, 2024, the Rollover Holders entered into the Rollover Agreements with Ultimate Parent, Parent and Merger Sub, pursuant to which, among other things and on the terms and subject to the conditions set forth therein, the Rollover Holders have agreed to contribute all of their shares of Common Stock and/or Company Preferred Stock to Ultimate Parent immediately prior to the Effective Time in exchange for the issuance to the Rollover Holders of limited partnership interests in Ultimate Parent. Additionally, certain of the Rollover Holders agreed pursuant to their respective Rollover Agreements, on the terms and subject to the conditions set forth therein, to vote all of their shares of Common Stock and/or Company Preferred Stock in favor of the adoption of the Merger Agreement. The Rollover Holders collectively hold, as of the date hereof, approximately 64% of the outstanding shares of Common Stock and all of the outstanding shares of Company Series A Preferred Stock and Company Series B Preferred Stock. The foregoing description of the Rollover Agreements does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the form of Rollover Agreement, a copy of which is attached to this Amendment No. 8 as Exhibit 4 and is incorporated by reference herein. Equity Commitment Letter and Limited Guarantee In connection with the execution of the Merger Agreement, on December 23, 2024, NEA 14, NEA 16, NEA 17 and NEA 18 VGE (the "Sponsors") entered into (a) an equity commitment letter (the "Equity Commitment Letter") with Parent, pursuant to which, on the terms and subject to the conditions set forth therein, the Sponsors agreed to provide certain equity financing to Parent up to an aggregate amount as set forth therein for the purpose of financing the Merger Consideration and the other payment obligations of Parent, Merger Sub and, following the Effective Time, the Issuer under the Merger Agreement and (b) a limited guaranty in favor of the Issuer, pursuant to which, on the terms and subject to the conditions set forth therein, the Sponsors guaranteed to the Issuer the payment of all of the liabilities and obligations of Parent and Merger Sub under the Merger Agreement, subject to an aggregate cap as set forth therein. The Issuer is a third party beneficiary of the Equity Commitment Letter and has the right to seek specific performance of the Sponsors' obligations to fund the equity financing provided for therein on the terms and subject to the conditions set forth therein and in the Merger Agreement.
