RECITALS    WHEREAS, the Stockholders hold shares of the Company’s common stock (the “Common Stock”); and  WHEREAS, the Stockholders desire to sell, and the Company desires to repurchase, an aggregate of  3,500,000 shares of Common Stock (the “Shares”) on the terms and subject to the conditions set forth in this  Agreement (the “Repurchase”):   NOW, THEREFORE, in consideration of the promises, covenants and agreements herein contained, the  parties agree as follows:  AGREEMENT    SECTION 1. REPURCHASE OF SHARES FOR CASH.  1.1 Repurchase. At the Closing (as defined below), the Company hereby agrees to repurchase from the  Stockholders, and each of the Stockholder hereby agrees to sell, assign and transfer to the Company, all of the  Stockholder’s right, title and interest in and to the Shares at the per Share price of $12.75, for an aggregate repurchase  price of $44,625,000.00 (the “Repurchase Amount”), with each Stockholder selling the number of shares designated  next to such Stockholder’s name on Exhibit A hereto (for the applicable repurchase price noted therein). Each  Stockholder shall complete and execute a Transfer Request Form, bearing an appropriate medallion signature  guarantee (only if required by the Company’s transfer agent), in a form mutually agreed to by the parties hereto (the  “Transfer Request Form”), and at the Closing shall deliver the Transfer Request Form. The Repurchase Amount shall  be paid at the Closing by wire transfer of immediately available funds to an account or accounts to be designated by  the Stockholders.  1.2 Closing. The closing of the Repurchase (the “Closing”) shall take place at the offices of the  Company, 2300 Orchard Parkway, San Jose, California on the date hereof, or at such other time and place as the  parties hereto shall mutually agree.  The obligations of the Company to repurchase the Shares in the Repurchase shall  be subject to the accuracy of the representations and warranties on the part of each of the Stockholders contained  herein as of the date hereof and as of the date of the Closing and to the performance by each of the Stockholders of its  obligations hereunder.  The obligations of each Stockholder to sell the Shares in the Repurchase shall be subject to  the accuracy of the representations and warranties on the part of the Company contained herein as of the date hereof  and as of the date of the Closing and to the performance by the Company of its obligations hereunder.     1.3 Termination of Rights as the Stockholder. Upon payment of the Repurchase Amount and  completion of the Repurchase in accordance with the terms of this Agreement, the Shares shall cease to be outstanding  for any and all purposes, and the Stockholders shall no longer have any rights as a holder of the Shares, including any  rights that each of the Stockholders may have had under the Company’s Certificate of Incorporation or otherwise as a  holder of the Shares.  SECTION 2. STOCKHOLDER REPRESENTATIONS AND WARRANTIES.  In connection with the transactions provided for hereby, each of the Stockholders hereby represents and  warrants to the Company as follows:  2.1 Ownership of Shares. Such Stockholder has good and valid right, title and interest (legal and  beneficial) in and to all of the Shares set forth next to such Stockholder’s name on Exhibit A hereto, free and clear of  all liens, pledges, security interests, charges, claims, equity or encumbrances of any kind. Upon paying for the Shares  DocuSign Envelope ID: 781C72D0-64DE-4C9B-B9F2-8AD8BAAA0A55 

 

  4871-0502-9937.v2  in accordance with this Agreement, the Company will acquire good and valid title to the Shares, free and clear of all  liens, pledges, security interests, charges, claims, equity or encumbrances of any kind.     2.2 Authorization. Such Stockholder has all necessary right, capacity, power and authority to execute,  deliver and perform such Stockholder’s obligations under this Agreement and all agreements, instruments and  documents contemplated hereby and to sell and deliver the Shares being sold hereunder, and this Agreement  constitutes a valid and binding obligation of such Stockholder.  2.3 No Conflict. The execution and delivery of this Agreement and the consummation of the  transactions contemplated hereby will not result in a breach by such Stockholder of, or constitute a default by such  Stockholder under, any agreement, instrument, decree, judgment or order to which such Stockholder is a party or by  which such Stockholder may be bound.  2.4 Experience and Evaluation. By reason of such Stockholder’s business or financial experience or  the business or financial experience of such Stockholder’s professional advisers who are unaffiliated with the  Company and who are not compensated by the Company, such Stockholder has the capacity to protect such  Stockholder’s own interests in connection with the sale of the Shares to the Company. Such Stockholder is capable of  evaluating the potential risks and benefits of the sale hereunder of the Shares.  Such Stockholder is sophisticated and  capable of understanding and appreciating, and does understand and appreciate, that future events may occur that  result in an increased value of the Shares owned by such Stockholder, and that such Stockholder would be deprived  of the opportunity to participate in any gain that might have resulted if such Stockholder had not transferred the Shares  owned by such Stockholder to the Company hereunder.  2.5 Access to Information. Such Stockholder represents that such Stockholder has access to and has  carefully reviewed the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, all  subsequent public filings of the Company with the Securities and Exchange Commission, other publicly available  information regarding the Company, and such other information that it and its advisers deem necessary to make its  decision to sell the Shares to the Company.  Such Stockholder further represents that such Stockholder has had an  opportunity to ask questions and receive answers from the Company regarding the business, properties, prospects and  financial condition of the Company and to seek from the Company such additional information as such Stockholder  has deemed necessary.  2.6 Tax Matters. Such Stockholder has had an opportunity to review with such Stockholder’s tax  advisers the federal, state, local and foreign tax consequences of the Repurchase and the transactions contemplated by  this Agreement. Such Stockholder is relying solely on such advisers and not on any statements or representations of  the Company or any of its agents. Such Stockholder understands that such Stockholder (and not the Company) shall  be responsible for such Stockholder’s tax liability and any related interest and penalties that may arise as a result of  the transactions contemplated by this Agreement.  2.7 Finders.  Such Stockholder has not engaged any investment banker, broker, or finder in connection  with the transactions contemplated hereunder, and no broker’s or similar fee is payable by such Stockholder or any of  its affiliates in connection with the transfer of the Shares owned by such Stockholder hereunder.  2.8 Stabilization Activity. Such Stockholder has not taken, directly or indirectly, any action designed  to, or that would constitute or might reasonably be expected to cause or result in, under the Securities Exchange Act  of 1934, as amended (and the rules and regulations promulgated thereunder) (the “Exchange Act”) or otherwise,  stabilization or manipulation of the price of any security of the Company in connection with the transfer of the Shares  owned by such Stockholder hereunder.  2.9 Certain Information. Such Stockholder acknowledges and understands that (i) the Company  possesses material nonpublic information not known to such Stockholder that may impact the value of the Common  Stock (the “Information”), and that the Company is not disclosing the Information to such Stockholder. Such  Stockholder understands, based on its experience, the disadvantage to which such Stockholder is subject due to the  disparity of information between such Stockholder and the Company. Notwithstanding such disparity, such  Stockholder has deemed it appropriate to enter into this Agreement and to consummate the repurchase of the Shares.  Such Stockholder agrees that none of the Company, its affiliates, stockholders, directors, employees and agents shall  DocuSign Envelope ID: 781C72D0-64DE-4C9B-B9F2-8AD8BAAA0A55 

 

  4871-0502-9937.v2  have liability to such Stockholder or its agents, grantors or beneficiaries, whatsoever due to or in connection with the  Company’s use or non-disclosure of the Information or otherwise as a result of the repurchase of the Shares, and such  Stockholder hereby irrevocably waives any claim that it might have based on the failure of the Company to disclose  the Information.  SECTION 3. COMPANY REPRESENTATIONS AND WARRANTIES; COMPANY COVENANTS.  In connection with the transactions provided for hereby, the Company represents and warrants to the  Stockholders as follows:  3.1 Organization. The Company is a corporation duly incorporated, validly existing and in good  standing under the laws of the State of Delaware.   3.2 Authorization. The Company has all necessary power and authority to execute, deliver and perform  the Company’s obligations under this Agreement and all agreements, instruments and documents contemplated hereby  and to purchase the Shares being sold hereunder, and this Agreement constitutes a valid and binding obligation of the  Company.  3.3 No Conflict. The execution and delivery of this Agreement and the consummation of the  transactions contemplated hereby (i) will not result in a breach by the Company of, or constitute a default by the  Company under, any agreement, instrument, decree, judgment or order to which the Company is a party or by which  the Company may be bound, and (ii) will not result in a breach or violation of any law, rule or regulation applicable  to the Company, including the Securities Act of 1933, as amended (and the rules and regulations promulgated  thereunder) (the “Securities Act”), the Exchange Act, and the rules and regulations of the New York Stock Exchange.    3.4 No Consents.

Except as otherwise provided herein, the terms and conditions of this Agreement shall inure to the benefit of and be  binding upon the respective successors and assigns of the parties (including transferees of any Shares).

WAIVER OF JURY TRIAL.  EACH OF THE PARTIES TO THIS AGREEMENT, AFTER CONSULTING OR HAVING HAD THE  OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY  WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION  BASED UPON OR ARISING OUT OF THIS AGREEMENT OR ANY RELATED INSTRUMENT OR  AGREEMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY, OR ANY COURSE OF  CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF ANY OF THEM.

Such remedies will not be the exclusive remedies for a  breach of this Agreement, but will be in addition to all other remedies available at law or in equity.  SECTION 9. ENTIRE AGREEMENT.  This Agreement contains the entire understanding of the parties, and there are no further or other agreements or  understandings, written or oral, in effect between the parties relating to the subject matter hereof, except as expressly  referred to herein.

SECTION 16. COUNTERPARTS.  This Agreement and any amendments to this Agreement may be executed in one or more textually-identical  counterparts, all of which will be considered one and the same agreement and will become effective when one or more  counterparts have been signed by each of the parties to this Agreement and delivered to the other parties to this  Agreement, it being understood that all parties to this Agreement need not sign the same counterpart. Any such  counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to electronic mail (any such  delivery, an “Electronic Delivery”), will be treated in all manner and respects as an original executed counterpart and  will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in  person. No party to this Agreement may raise the use of an Electronic Delivery to deliver a signature, or the fact that  any signature or agreement or instrument was transmitted or communicated through the use of an Electronic Delivery,  as a defense to the formation of a contract, and each party to this Agreement forever waives any such defense, except  to the extent such defense relates to lack of authenticity.

PROMISSORY NOTE

 

	Total Principal Amount: up to $750,000	Dated as of September 9, 2022

(as set forth on the Schedule
of Borrowings attached hereto)

 

Tailwind Acquisition Corp., a Delaware corporation
and blank check company (the “Maker”), promises to pay to the order of Tailwind Sponsor LLC, a Delaware limited liability
company, or its registered assigns or successors in interest (the “Payee”), the Total Principal Amount (as defined
below) in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be
made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the Payee may
from time to time designate by written notice in accordance with the provisions of this Note.

 

1.            Principal.
The initial principal balance of this Note of $600,000, funded on the date hereof by the Payee (the “Initial Principal Amount”),
together with any funds drawn down by the Maker following the date hereof pursuant to Section 3 below (together with the Initial
Principal Amount, the “Total Principal Amount”) shall be payable on the consummation of the Maker’s initial
merger, stock exchange, asset acquisition, stock purchase, recapitalization, reorganization or similar business combination with one
or more businesses or entities (a “Business Combination”). The Payee understands that if a Business Combination is
not consummated, this Note will be repaid solely to the extent that the Maker has funds available to it outside of its trust account
established in connection with its initial public offering of its securities (the “Trust Account” and such offering,
the “IPO”), and that all other amounts will be contributed to capital, forfeited, eliminated or otherwise forgiven
or eliminated.

 

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

 

3.             Drawdown Requests. Maker and Payee agree that Maker may request an additional aggregate amount of up to $150,000
(the “Maximum Drawdown Amount”), which may be drawn down in two equal tranches (each
a “Drawdown Request”). 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. The commencement by the Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization,
rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator,
assignee, trustee, custodian, sequestrator (or other similar official) of the Maker or for any substantial part of its property, or
the making by it of any assignment for the benefit of creditors, or the failure of the Maker generally to pay its debts as such
debts become due, or the taking of corporate action by the Maker in furtherance of any of the foregoing. 

 

(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.

 

6.             Remedies.

 

(a) Upon the occurrence
of an Event of Default specified in Section 5(a) hereof, the Payee may, by written notice to the Maker, declare this Note to be due immediately
and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable hereunder, shall become immediately due
and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained
herein or in the documents evidencing the same to the contrary notwithstanding. 

 

(b) Upon the occurrence
of an Event of Default specified in Sections 5(b) and 5(c), the unpaid principal balance of this Note, and all other sums payable with
regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of the Payee.

 

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.

 

9.             Waivers. The Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand,
notice of dishonor, protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted
by the Payee under the terms of this Note, and all benefits that might accrue to the Maker by virtue of any present or future laws exempting
any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale
under execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and the Maker
agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued
hereon, may be sold upon any such writ in whole or in part in any order desired by the Payee.

 

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.

 

11.           Notices. All notices, statements or other documents which are required or contemplated by this Note shall be: (i) in writing
and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission
to the address designated in writing, (ii) by facsimile to the number most recently provided to such party or such other address or fax
number as may be designated in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided
to such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so
transmitted shall be deemed to have been given on the day of delivery, if delivered personally, on the business day following receipt
of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight courier
service or five (5) days after mailing if sent by mail.

 

12.           Construction. THIS NOTE SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF NEW YORK, WITHOUT REGARD TO CONFLICT
OF LAW PROVISIONS THEREOF.

 

13.           Severability. 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
