2

successor provisions or amendments thereto) and the time period set forth in clause (iii) of the foregoing sentence shall end on the earliest of the following to occur (the “SPAC Outside Date”): (x) twelve (12) months after the consummation of the SPAC Transaction; (y) the date following the consummation of the SPAC Transaction on which the Company consummates a liquidation, merger, stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange such stockholders’ shares received in the SPAC Transaction (the “SPAC Shares”) for (or having such SPAC Shares converted into) cash, securities or other property (or the right to receive any of the foregoing), other than any holding company reorganization or a transaction that is intended solely to effect a redomestication; and (z) the date upon which the reported closing price of the SPAC Shares equals or exceeds $15.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any twenty (20) trading days within any thirty (30)-trading day period commencing at least one hundred fifty (150) days following the closing of the SPAC Transaction (the “Price Condition”), provided that the Price Condition shall not be deemed satisfied until there is an effective registration statement covering the SPAC Shares. The first sentence of this Section 2.11 shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement in connection with an IPO, or the transfer of any shares to any trust for the direct or indirect benefit of the Holder or the immediate family of the Holder, provided that the trustee of the trust agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, and shall be applicable to the Holders only if all officers and directors are subject to the same restrictions and the Company uses commercially reasonable efforts to obtain a similar agreement from all stockholders individually owning more than 1% stockholders of the Company’s outstanding Common Stock (after giving effect to conversion into Common Stock of all outstanding Preferred Stock). The underwriters, if any, in connection with an IPO, and the Surviving Company, in connection with a SPAC Transaction, are intended third-party beneficiaries of this Subsection 2.11 and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be requested by the underwriters in connection with the IPO, or by the Company in connection with the Direct Listing or a SPAC Transaction, that are consistent with this Section 2.11 or that are necessary to give further effect thereto (“Lock-Up Agreements”). Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all Holders subject to such agreements, based on the number of shares subject to such agreements. In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with respect to the Registrable Securities (and the shares or securities of every other person subject to the foregoing restriction) until the end of the applicable period.

3

Notwithstanding anything to the contrary in this Agreement, the covenants of the Holders set forth in this Section 2.11 shall survive the termination of this Agreement (including, for the avoidance of doubt, the consummation of an IPO, the effectiveness of the Form S-1 in a Direct Listing and commencement of trading in connection therewith, or the closing of a SPAC Transaction) with respect to a Holder until such time as such Holder has executed a Lock-Up Agreement in a form satisfactory to the underwriters in connection with the IPO or to the Company in connection with the Direct Listing or a SPAC Transaction.”

3. Continued Validity of Rights Agreement. Except as specifically amended hereby, the Rights Agreement shall continue in full force and effect as originally constituted and is ratified and affirmed by the parties hereto.

4. Successors and Assigns. Except as otherwise provided herein, the terms and conditions of this Amendment shall inure to the benefit of and be binding upon the respective successors and assigns of the parties.

5. Governing Law. This Amendment shall be governed by and construed in accordance with the internal laws of the State of New York, without regard to its principles of conflicts of laws.

6. Counterparts. This Amendment may be executed and delivered by electronic or facsimile signature and in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
