AMENDMENT
TO THE
AMENDED AND RESTATED
CERTIFICATE OF INCORPORATION
OF

TAILWIND ACQUISITION CORP.

Pursuant to Section 242 of the
Delaware General Corporation Law

TAILWIND ACQUISITION CORP. (the “Corporation”), a corporation organized and existing under the laws of the State of Delaware, does hereby certify as follows:

1.     The name of the Corporation is “Tailwind Acquisition Corp.” The original certificate of incorporation of the Corporation was filed with the Secretary of State of the State of Delaware on May 29, 2020 (the “Original Certificate”). An amended and restated certificate of incorporation of the Corporation was filed with the Secretary of State of the State of Delaware on September 1, 2020 (the “Amended and Restated Certificate of Incorporation”).

2.      This Amendment to the Amended and Restated Certificate of Incorporation amends the Amended and Restated Certificate of Incorporation of the Corporation.

3.      This Amendment to the Amended and Restated Certificate of Incorporation was duly adopted by the affirmative vote of the holders of 65% of the stock entitled to vote at a meeting of stockholders in accordance with the provisions of Section 242 of the General Corporation Law of the State of Delaware (the “DGCL”).

4.      The text of Section 9.1(b) of Article IX is hereby amended and restated to read in full as follows:

(b)    Immediately after the Offering, a certain amount of the net offering proceeds received by the Corporation in the Offering (including the proceeds of any exercise of the underwriter’s over-allotment option) and certain other amounts specified in the Corporation’s registration statement on Form S-1, as initially filed with the Securities and Exchange Commission on August 18, 2020 (as amended, the “Registration Statement”), shall be deposited in a trust account (the “Trust Account”), established for the benefit of the Public Stockholders (as defined below) pursuant to a trust agreement described in the Registration Statement. Except for the withdrawal of interest to pay franchise and income taxes, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust Account) will be released from the Trust Account until the earliest of (i) the completion of the initial Business Combination, (ii) the redemption of 100% of the Offering Shares (as defined below) if the Corporation does not complete its initial Business Combination within 28 months (or up to 30 months, if applicable under the provisions of Section 9.2(d)) from the closing of the Offering and (iii) the redemption of shares in connection with a vote seeking to amend any provisions of the Amended and Restated Certificate relating to stockholders’ rights or pre-initial Business Combination activity (as described in Section 9.7). Holders of shares of the Corporation’s Common Stock included as part of the units sold in the Offering (the “Offering Shares”) (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are members or affiliates of Tailwind Sponsor LLC (the “Sponsor”) or officers or directors of the Corporation) are referred to herein as “Public Stockholders.”

(d)       In the event that the Corporation has not consummated an initial Business Combination within 28 months from the closing of the Offering, the Corporation shall (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the Offering Shares in consideration of a per-share price, payable in cash, equal to the quotient obtained by dividing (A) the aggregate amount then on deposit in the Trust Account, including interest not previously released to the Corporation to pay its franchise and income taxes (less up to $100,000 of such net interest to pay dissolution expenses), by (B) the total number of then outstanding Offering Shares, which redemption will completely extinguish rights of the Public Stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Board in accordance with applicable law, dissolve and liquidate, subject in each case to the Corporation’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

Notwithstanding the foregoing or any other provisions of the Articles of this Amended and Restated Certificate, in the event that the Corporation has not consummated an initial Business Combination within 28 months from the closing of the Offering, the Corporation may, without another stockholder vote, elect to extend the date to consummate the Business Combination on a monthly basis for up to two times by an additional one month each time after the 28 months from the closing of the Offering, by resolution of the Board if requested by the Sponsor, and upon five days’ advance notice prior to the applicable deadlines, until 30 months from the closing of the Offering, provided that the Sponsor (or one or more of its affiliates, members or third-party designees ) (the “Lender”) will deposit into the Trust Account for each such monthly extension $75,000, in exchange for one or more non-interest bearing, unsecured promissory notes issued by the Corporation to the Lender. If the Corporation completes the Business Combination, it will, at the option of the Lender, repay the amounts loaned under the promissory note(s) or convert a portion or all of the amounts loaned under such promissory note(s) into warrants at a price of $1.00 per warrant, which warrants will be identical to the private placement warrants issued to the Sponsor at the time of the Offering. If the Corporation does not complete the Business Combination by the deadline to consummate the Business Combination, such promissory notes will be repaid only from funds held outside of the Trust Account.

Additional Redemption Rights. If, in accordance with Section 9.1(a), any amendment is made to this Amended and Restated Certificate of Incorporation (i) that would affect the substance or timing of the Corporation’s obligation to provide Public Stockholders the right to have their shares of Class A Common Stock redeemed in connection with an initial Business Combination or to redeem 100% of the Offering Shares if the Corporation has not consummated an initial Business Combination within 28 months (or up to 30 months, if applicable under the provisions of Section 9.2(d)) from the date of the Closing or (ii) with respect to any other provisions relating to the rights of holders of the Class A Common Stock, the Public Stockholders shall be provided with the opportunity to redeem their Offering Shares upon the approval of any such amendment, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest not previously released to the Corporation to pay its franchise and income taxes, divided by the number of then outstanding Offering Shares. The Corporation’s ability to provide such opportunity is subject to the Redemption Limitation.

IN WITNESS WHEREOF, Tailwind Acquisition Corp. has caused this Amendment to the Amended and Restated Certificate of Incorporation to be duly executed in its name and on its behalf by an authorized officer as of this 9^th day of September, 2022.

2.                 Interest. No interest shall accrue on the unpaid principal balance of this Note.

Each Drawdown Request must be for fifty percent 50% of the Maximum Drawdown Amount unless agreed upon by Maker and Payee. Payee shall fund each Drawdown Request no later than three (3) business days after receipt of a Drawdown Request. Once an amount is drawn down under this Note, it shall not be available for future Drawdown Requests even if prepaid. No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.

4.            Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.

5.             Events of Default. The following shall constitute an event of default (“Event of Default”):

(a) Failure to Make Required Payments. Failure by the Maker to pay the principal amount due pursuant to this Note within five (5) business days following the date when due.

(b) Voluntary Bankruptcy, Etc.

(c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of the Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of sixty (60) consecutive days.

7.             Conversion. Upon consummation of a Business Combination, the Payee shall have the option, but not the obligation, to convert the Total Principal Amount of this Note, in whole or in part at the option of the Payee, into warrants of the Maker (each, a “Warrant”), at a price of $1.00 per Warrant, each Warrant exercisable for one share of Class A common stock, $0.0001 par value per share, of the Maker (the “Class A Stock”). The Warrants shall be identical to the private placement warrants issued to the Sponsor at the time of the Maker’s IPO. As promptly as reasonably practicable after notice by the Payee to the Maker to convert the principal balance of this Note, in whole or in part, into Warrants, which notice must be made at least five (5) business days prior to the consummation of the Business Combination, and after the Payee’s surrender of this Note, the Maker shall have issued and delivered to the Payee, without any charge to Payee, a warrant certificate or certificates (issued in the name(s) requested by the Payee), or shall have made appropriate book-entry notation on the books and records of the Maker, in each case for the number of Warrants of the Maker issuable upon the conversion of this Note.

8.             Covenants of the Maker. The Maker covenants that any Warrants issuable upon conversion of the Note, when so issued, will be validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issuance thereof.

10.           Unconditional Liability. The Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by the Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by the Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to the Maker or affecting the Maker’s liability hereunder.

Any provision contained in this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

14.           Trust Waiver. Notwithstanding anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any monies in, or any distribution of or from, the Trust Account, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever. The Payee hereby agrees not to make any Claim against the Trust Account (including any distributions therefrom), regardless of whether such Claim arises as a result of, in connection with or relating in any way to, this Note, or any other matter, and regardless of whether such Claim arises based on contract, tort, equity or any other theory of legal liability. To the extent the Payee commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to the Maker (including this Note), which proceeding seeks, in whole or in part, monetary relief against the Maker, the Payee hereby acknowledges and agrees that its sole remedy shall be against funds held outside of the Trust Account and that such Claim shall not permit the Maker (or any person claiming on its behalf or in lieu of it) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein.

15.           Tax Treatment. In each case for U.S. federal income tax and all other applicable tax purposes, the Maker and the Payee agree to treat this Note as an equity interest in the Maker, and shall take no contrary position on any tax return or before any taxing authority unless otherwise required by law). The Maker and the Payee shall reasonably cooperate to structure (i) any conversion of this Note in connection with a Business Combination and (ii) any contribution, forfeiture or elimination of this Note pursuant to Section 1 in a manner that is tax-efficient for the Maker and the Payee, taking into account the terms of any Business Combination.
