Within one (1) Business Day after completion of each Additional Accelerated Purchase Date, the Investor will provide to the Company a
written confirmation of each Additional Accelerated Purchase on such Additional Accelerated Purchase Date setting forth the applicable
Additional Accelerated Purchase Share Amount and Additional Accelerated Purchase Price for each such Additional Accelerated Purchase
on such Additional Accelerated Purchase Date (each, an “Additional Accelerated Purchase Confirmation”). Notwithstanding
the foregoing, the Company shall not deliver any Additional Accelerated Purchase Notices during the PEA Period.

 

(d)               
Payment for Purchase Shares. For each Regular Purchase, the Investor shall pay to the Company an amount equal to the Purchase
Amount with respect to such Regular Purchase as full payment for such Purchase Shares via wire transfer of immediately available funds
on the same Business Day that the Investor receives such Purchase Shares, if such Purchase Shares are received by the Investor before
1:00 p.m., Eastern time, or, if such Purchase Shares are received by the Investor after 1:00 p.m., Eastern time, the next Business Day.
For each Accelerated Purchase and each Additional Accelerated Purchase, the Investor shall pay to the Company an amount equal to the
Purchase Amount with respect to such Accelerated Purchase and Additional Accelerated Purchase, respectively, as full payment for such
Purchase Shares via wire transfer of immediately available funds on the second Business Day following the date that the Investor receives
such Purchase Shares. If the Company or the Transfer Agent shall fail for any reason or for no reason to electronically transfer any
Purchase Shares as DWAC Shares in respect of a Regular Purchase, an Accelerated Purchase or an Additional Accelerated Purchase (as applicable)
within two (2) Business Days following the receipt by the Company of the Purchase Price, Accelerated Purchase Price and Additional Accelerated
Purchase Price, respectively, therefor in compliance with this Section 2(d), and if on or after such Business Day the Investor
purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Investor of
such Purchase Shares that the Investor anticipated receiving from the Company in respect of such Regular Purchase, Accelerated Purchase
or Additional Accelerated Purchase (as applicable), then the Company shall, within two (2) Business Days after the Investor’s request,
either (i) pay cash to the Investor in an amount equal to the Investor’s total purchase price (including brokerage commissions,
if any) for the shares of Common Stock so purchased (the “Cover Price”), at which point the Company’s obligation
to deliver such Purchase Shares as DWAC Shares shall terminate, or (ii) promptly honor its obligation to deliver to the Investor such
Purchase Shares as DWAC Shares and pay cash to the Investor in an amount equal to the excess (if any) of the Cover Price over the total
Purchase Amount paid by the Investor pursuant to this Agreement for all of the Purchase Shares to be purchased by the Investor in connection
with such Regular Purchase, Accelerated Purchase and Additional Accelerated Purchase (as applicable). If the issuance would result in
the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up or down to
the nearest whole share. All payments made under this Agreement shall be made in lawful money of the United States of America or wire
transfer of immediately available funds to such account as the Company may from time to time designate by written notice in accordance
with the provisions of this Agreement. Whenever any amount expressed to be due by the terms of this Agreement is due on any day that
is not a Business Day, the same shall instead be due on the next succeeding day that is a Business Day.

 

    8

     

    

 

(e)               
Beneficial Ownership Limitation. Notwithstanding anything to the contrary contained in this Agreement, the Company shall
not issue or sell, and the Investor shall not purchase or acquire, any shares of Common Stock under this Agreement which, when aggregated
with all other shares of Common Stock then beneficially owned by the Investor and its affiliates (as calculated pursuant to Section 13(d)
of the Exchange Act and Rule 13d-3 promulgated thereunder), would result in the beneficial ownership by the Investor and its affiliates
of more than 9.99% of the then issued and outstanding shares of Common Stock (the “Beneficial Ownership Limitation”).
Upon the written or oral request of the Investor, the Company shall promptly confirm orally or in writing to the Investor the number
of shares of Common Stock then outstanding. The Investor and the Company shall each cooperate in good faith in the determinations required
hereby and the application hereof. The Investor’s written certification to the Company of the applicability of the Beneficial Ownership
Limitation, and the resulting effect thereof hereunder at any time, shall be conclusive with respect to the applicability thereof and
such result absent manifest error.

 

(f)                
Compliance with Principal Market Rules.

 

(i)                
Exchange Cap. Subject to Section 2(f)(ii) below, the Company shall not issue or sell any shares of Common Stock pursuant
to this Agreement, and the Investor shall not purchase or acquire any shares of Common Stock pursuant to this Agreement, to the extent
that after giving effect thereto, the aggregate number of shares of Common Stock that would be issued pursuant to this Agreement and
the transactions contemplated hereby would be equal to or greater than a number of shares of Common Stock representing 19.99% of the
shares of Common Stock outstanding on the date of Closing (which number of shares shall be reduced, on a share-for-share basis, by the
number of shares of Common Stock issued or issuable pursuant to any transaction or series of transactions that may be aggregated with
the transactions contemplated by this Agreement under applicable rules of the New York Stock Exchange or any other Principal Market on
which the shares of Common Stock may be listed or quoted) (the “Exchange Cap”), unless stockholder approval is obtained
to issue in excess of the Exchange Cap. Notwithstanding the foregoing, the Company shall not be required or permitted to issue, and the
Investor shall not be required to purchase, any shares of Common Stock under this Agreement if such issuance would violate the rules
or regulations of the Principal Market.

 

(ii)              
General. The Company shall not issue any Securities pursuant to this Agreement if such issuance would reasonably be expected
to result in (A) a violation of the Securities Act or (B) a breach of the rules and regulations of the Principal Market. Furthermore,
the Company agrees that it shall not issue any Securities pursuant to this Agreement if, at the time of such issuance (Y) the effectiveness
of the Registration Statement registering the Securities has lapsed for any reason (including, without limitation, the issuance of a
stop order or similar order) or (Z) the Registration Statement is unavailable for the sale by the Company to the Investor (or the resale
by the Investor, as the case may be) of any or all of the Securities to be issued to the Investor under the Transaction Documents. The
provisions of this Section 2(f) shall be implemented in a manner otherwise than in strict conformity with the terms hereof only if necessary
to ensure compliance with the Securities Act and the rules and regulations of the Principal Market.

 

		3.	INVESTOR’S REPRESENTATIONS AND WARRANTIES.

 

The Investor represents and
warrants to the Company and Nuburu that as of the date hereof and as of the Commencement Date:

 

(a)               
 Organization; Authority. The Investor is an entity duly organized, validly existing and in good standing under the laws
of the jurisdiction of its organization, with the requisite power and authority to enter into, and to consummate the transactions contemplated
by, this Agreement and any other Transaction Document to which the Investor is a party and otherwise to carry out its obligations hereunder
and thereunder.

 

(b)               
Investment Purpose. The Investor is acquiring the Securities as principal for its own account and not with a view to or
for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities
law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable state securities
law and has no direct or indirect arrangement or understandings with any other Persons to distribute or regarding the distribution of
such Securities in violation of the Securities Act or any applicable state securities law (this representation and warranty not limiting
the Investor’s right to sell the Securities at any time pursuant to the Registration Statement described herein or otherwise in
compliance with applicable federal and state securities laws). The Investor is acquiring the Securities hereunder in the ordinary course
of its business.

 

(c)               
Accredited Investor Status. The Investor is an “accredited investor” as that term is defined in Rule 501(a)(3)

(d)               
Reliance on Exemptions. The Investor understands that the Securities may be offered and sold to it in reliance on specific
exemptions from the registration requirements of United States federal and state securities laws and that each of the Company and Nuburu
is relying in part upon the truth and accuracy of, and the Investor’s compliance with, the representations, warranties, agreements,
acknowledgments and understandings of the Investor set forth herein in order to determine the availability of such exemptions and the
eligibility of the Investor to acquire the Securities.

 

    9

     

    

 

(e)

experience in financial and business matters that it is capable of evaluating the merits and risks of the proposed investment in the
Securities and (iii) has had an opportunity to ask questions of and receive answers from the officers of each of the Company and Nuburu
concerning the financial condition and business of the Company and Nuburu and other matters related to an investment in the Securities.
Neither such inquiries nor any other due diligence investigations conducted by the Investor or its representatives shall modify, amend
or affect the Investor’s right to rely on the Company’s and Nuburu’s representations and warranties contained in Section
4 below. The Investor has sought such accounting, legal and tax advice from its own independent advisors as it has considered necessary
to make an informed investment decision with respect to its acquisition of the Securities. The Investor understands that it (and not
the Company or Nuburu) shall be responsible for its own tax liabilities that may arise as a result of this investment or the transactions
contemplated by this Agreement.

 

(f)                
No Governmental Review. The Investor understands that no U.S. federal or state agency or any other government or governmental

unless (A) registered pursuant to the Securities Act or (B) an exemption exists permitting such Securities to be sold, assigned or transferred
without such registration; (ii) any sale of the Securities made in reliance on Rule 144 promulgated under the Securities Act (“Rule
144”) may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the
Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as
that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and
regulations of the SEC thereunder.

 

(h)               
Validity; Enforcement. This Agreement and the Registration Rights Agreement have been duly and validly authorized, executed
and delivered on behalf of the Investor and each is a valid and binding agreement of the Investor enforceable against the Investor in
accordance with its terms, subject as to enforceability to general principles of equity and to applicable bankruptcy, insolvency, reorganization,
moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights
and remedies.

 

(i)                
Residency. The Investor is a resident of the State of Illinois.

 

(j)                
No Short Selling. The Investor represents and warrants to the Company and Nuburu that at no time prior to the date of this

a net short position with respect to shares of SPAC Common Stock or Common Stock.

organizational documents or any Certificate of Designations, Preferences and Rights of any outstanding series of preferred stock of the
Company or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default)
under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument
to which the Company or any of its Subsidiaries is a party, or result in a violation of any law, rule, regulation, order, judgment or
decree (including federal and state securities laws and regulations and the rules and regulations of the Principal Market applicable
to the Company or any of its Subsidiaries) or by which any property or asset of the Company or any of its Subsidiaries is bound or affected,
except in the case of conflicts, defaults, terminations, amendments, accelerations, cancellations and violations under clause (ii), which

or any regulatory or self-regulatory agency in order for it to execute, deliver or perform any of its obligations under or contemplated
by the Transaction Documents in accordance with the terms hereof or thereof. Except as set forth elsewhere in this Agreement or the Registration
Rights Agreement (including with respect to the receipt of stockholder approval for any issuances in excess of the Excess Cap), all consents,
authorizations, orders, filings and registrations which the Company is required to obtain pursuant to the preceding sentence shall be
obtained or effected on or prior to the Commencement Date.

 

    11

     

    

 

(vi)             
SEC Documents; Financial Statements. The Company has filed, and upon consummation of the Merger, the Company shall have
filed all reports, schedules, forms, statements and other documents required to be filed by the Company under the Securities Act and
the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof for such period as the Company was required by law or regulation
to file such material (the foregoing materials, including the exhibits thereto and documents incorporated by reference therein, being
collectively referred to herein as the “SEC Documents”). As of their respective dates, or, if amended or restated,
as of the date of such amendment or restatement, the SEC Documents complied in all material respects with the requirements of the Securities
Act and the Exchange Act, as applicable. None of the SEC Documents contained, when filed or, if amended or restated, as of the date of
such amendment or restatement with respect to those disclosures that are amended or restated any untrue statement of a material fact
or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading. Except as set forth in the SEC Documents, the financial statements of
the Company included in the SEC Documents comply in all material respects with applicable accounting requirements and the rules and regulations
of the SEC with respect thereto as in effect at the time of filing, or if amended or restated, as of the date of such amendment or restatement.
Such financial statements have been prepared in accordance with United States generally accepted accounting principles applied on a consistent
basis during the periods involved (“GAAP”), except as may be otherwise specified in such financial statements or the
notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all
material respects the financial position of the Company and its consolidated Subsidiaries as of and for the dates thereof and the results
of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end
audit adjustments. Except as set forth in the SEC Documents or in connection with the SEC’s review of the Form S-4, the Company
has received no notices or correspondence from the SEC for the one year preceding the date hereof. To the knowledge of the Company, the
SEC has not commenced any enforcement proceedings against the Company or any of its Subsidiaries.

 

(vii)

thereby. The Company further acknowledges that the Investor is not acting as a financial advisor or fiduciary of the Company (or in any
similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby. The Company represents
that it has not received any advice given by the Investor or any of its representatives or agents in connection with the Transaction
Documents and the transactions contemplated hereby and thereby. The Company further represents to the Investor that the Company’s

affiliates that it controls, nor any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security
or solicited any offers to purchase any security, under circumstances that would require registration of the offer and sale of any of
the Securities under the Securities Act, whether through aggregation or integration with prior offerings or otherwise, or cause this
offering of the Securities to be aggregated or integrated with prior offerings by the Company in a manner that would require stockholder
approval pursuant to the rules of the Principal Market on which any of the securities of the Company are to be listed or designated.
The issuance and sale of the Securities hereunder, as of the date of this Agreement, does not contravene the rules and regulations of
the Principal Market.

 

(ix)             
Application of Takeover Protections. The Company and its Board of Directors have taken or will take prior to the Commencement
Date all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including
any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s organizational documents
or the laws of the jurisdiction of its incorporation which is or could become applicable to the Investor as a result of the transactions
contemplated by this Agreement, including, without limitation, the Company’s issuance of the Securities and the Investor’s
ownership of the Securities.

 

(x)               
Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by (i) the Transaction
Documents and (ii) the Business Combination Agreement, each of which will be timely publicly disclosed by the Company, the Company confirms
that neither it nor any other Person acting on its behalf has provided the Investor or its agents or counsel with any information that
it believes constitutes or might constitute material, non-public information which is not otherwise disclosed in the Registration Statement
or the SEC Documents. The Company understands and confirms that the Investor will rely on the foregoing representation in effecting purchases
and sales of securities of the Company. All of the disclosure furnished by or on behalf of the Company to the Investor regarding the
Company, its business and the transactions contemplated hereby is true and correct in all material respects and does not contain any
untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light
of the circumstances under which they were made, not misleading. The press releases disseminated by the Company during the twelve months
preceding the date of this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they
were made and when made, not misleading. The Company acknowledges and agrees that the Investor neither makes nor has made any representations
or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 3 hereof.

to its knowledge is likely to have the effect of, terminating the registration of the SPAC Common Stock, as of the date hereof, or the
Common Stock, as of the Commencement Date, pursuant to the Exchange Act nor has the Company received any notification that the SEC is
currently contemplating terminating such registration. The Company has not, in the twelve (12) months preceding the date hereof, received
any notice from any Person to the effect that the Company is not in compliance with the listing or maintenance requirements of the Principal
Market. The Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance with all
such listing and maintenance requirements.

 

(xv)           
No Market Manipulation. The Company has not, and to its knowledge no Person acting on its behalf has, (i) taken, directly

officer, other officer of the Company participating in the offering contemplated hereby, any beneficial owner of 20% or more of the Company’s
outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405
under the Securities Act) connected with the Company in any capacity at the time of sale (each, an “Issuer Covered Person”)
is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act
(a “Disqualification Event”), except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3) under the Securities
Act. The Company has exercised reasonable care to determine whether any Issuer Covered Person is subject to a Disqualification Event.

 Organization and Qualification. Nuburu is an entity duly incorporated or otherwise organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or organization, with the requisite corporate power and authority to
own and use its properties and assets and to carry on its business as currently conducted. Nuburu is not in violation or default of any
of the provisions of its certificate of incorporation or bylaws. Nuburu is duly qualified to conduct business and is in good standing
as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes
such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be, could not reasonably
be expected to result in a Nuburu Material Adverse Effect and no proceeding has been instituted in any such jurisdiction revoking, limiting
or curtailing or seeking to revoke, limit or curtail such power and authority or qualification. Nuburu has no Subsidiaries.

 

(ii)              
Authorization; Enforcement; Validity. (i) Nuburu has the requisite corporate power and authority to enter into and perform
its obligations under this Agreement, the Registration Rights Agreement and each of the other Transaction Documents, (ii) the execution
and delivery of the Transaction Documents by Nuburu and the consummation by it of the transactions contemplated hereby and thereby have
been duly authorized by Nuburu’s Board of Directors and no further consent or authorization is required by Nuburu, its Board of
Directors or its stockholders (except as provided in this Agreement or the Business Combination Agreement), (iii) each of this Agreement
and the Registration Rights Agreement has been, and each other Transaction Document shall be on the Commencement Date, duly executed
and delivered by Nuburu and (iv) each of this Agreement and the Registration Rights Agreement constitutes, and each other Transaction

in accordance with their terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy,
insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable
creditors’ rights and remedies. The Board of Directors of Nuburu has approved the resolutions (the “Nuburu Signing Resolutions”)
to authorize this Agreement, the Registration Rights Agreement and the transactions contemplated hereby. The Nuburu Signing Resolutions
are valid, in full force and effect and have not been modified or supplemented in any respect. Nuburu has delivered to the Investor a
true and correct copy of minutes of a meeting of the Board of Directors of Nuburu at which the Nuburu Signing Resolutions were duly adopted
by the Board of Directors or a unanimous written consent adopting the Nuburu Signing Resolutions executed by all of the members of the
Board of Directors of Nuburu. Except as set forth in this Agreement or the Business Combination Agreement, no other approvals or consents
of Nuburu’s Board of Directors, any authorized committee thereof, or stockholders is necessary under applicable laws and Nuburu’s
certificate of incorporation and bylaws to authorize the execution and delivery of the Transaction Documents or any of the transactions
contemplated thereby.

 

(iii)            
No Conflicts. The execution, delivery and performance of the Transaction Documents by Nuburu and the consummation by Nuburu
of the transactions contemplated hereby and thereby will not (i) result in a violation of Nuburu’s certificate of incorporation
or bylaws or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default)
under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument
to which Nuburu is a party, or result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state
securities laws and regulations applicable to Nuburu) or by which any property or asset of Nuburu is bound or affected, except in the
case of conflicts, defaults, terminations, amendments, accelerations, cancellations and violations under clause (ii), which could not
reasonably be expected to result in a Nuburu Material Adverse Effect. Nuburu is not in violation of any term of or in default under its
certificate of incorporation or bylaws. Nuburu is not in violation of any term of or is in default under any material contract, agreement,
mortgage, indebtedness, indenture, instrument, judgment, decree or order or any statute, rule or regulation applicable to Nuburu, except
for possible conflicts, defaults, terminations or amendments that could not reasonably be expected to have a Nuburu Material Adverse
Effect. The business of Nuburu is not being conducted, and shall not be conducted, in violation of any law, ordinance or regulation of
any governmental entity, except for possible violations, the sanctions for which either individually or in the aggregate could not reasonably
be expected to have a Nuburu Material Adverse Effect. Except as specifically contemplated by this Agreement and as required under the
Securities Act or applicable state securities laws, Nuburu is not required to obtain any consent, authorization or order of, or make
any filing or registration with, any court or governmental agency or any regulatory or self-regulatory agency in order for it to execute,
deliver or perform any of its obligations under or contemplated by the Transaction Documents in accordance with the terms hereof or thereof.
Except as set forth elsewhere in this Agreement, all consents, authorizations, orders, filings and registrations which Nuburu is required
to obtain pursuant to the preceding sentence shall be obtained or effected on or prior to the Commencement Date.

(iv)             
Absence of Certain Changes. Except as disclosed in the SEC Documents, since March 31, 2022, there has been no material
adverse change in the business, properties, operations, financial condition or results of operations of Nuburu. Nuburu has not taken
any steps, and does not currently expect to take any steps, to seek protection pursuant to any Bankruptcy Law nor does Nuburu have any
knowledge or reason to believe that its creditors intend to initiate involuntary bankruptcy or insolvency proceedings. Assuming Nuburu
receives the anticipated proceeds from the Merger, Nuburu is financially solvent and is generally able to pay its debts as they become
due.

 

(v)               
Absence of Litigation. There is no action, suit, proceeding, inquiry or, to Nuburu’s knowledge, investigation before
or by any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of Nuburu, threatened
against or affecting Nuburu, or any of Nuburu’s officers or directors in their capacities as such, which could reasonably be expected
to have a Nuburu Material Adverse Effect.

 

(vi)             
Acknowledgment Regarding Investor’s Status. Nuburu acknowledges and agrees that the Investor is acting solely in
the capacity of arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby.
Nuburu further acknowledges that the Investor is not acting as a financial advisor or fiduciary of Nuburu (or in any similar capacity)
with respect to the Transaction Documents and the transactions contemplated hereby and thereby. Nuburu represents that it has not received
any advice given by the Investor or any of its representatives or agents in connection with the Transaction Documents and the transactions
contemplated hereby and thereby. Nuburu further represents to the Investor that Nuburu’s decision to enter into the Transaction
Documents has been based solely on the independent evaluation by Nuburu and its representatives and advisors.

 

(vii)           
No General Solicitation. Neither Nuburu, nor any of its affiliates, nor any Person acting on its or their behalf, has engaged
in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection
with the offer or sale of the Securities.

 

(viii)         
Intellectual Property Rights. Nuburu owns or possesses adequate rights or licenses to use all trademarks, trade names,
service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions, licenses, approvals, governmental
authorizations, trade secrets and other intellectual property rights necessary to conduct its business as now conducted. None of Nuburu’s
rights in its owned and material trademarks, trade names, service marks, service mark registrations, service names, patents, patent rights,
copyrights, trade secrets or other intellectual property rights have expired or terminated, or, by the terms and conditions thereof,
could expire or terminate within two years from the date of this Agreement, in each case which could reasonably be expected to have a
Nuburu Material Adverse Effect. Nuburu does not have any knowledge of any infringement by Nuburu of any trademark, trade name rights,
patents, patent rights, copyrights, service names, service marks, service mark registrations, trade secret or other intellectual property
rights of others, and there is no claim, action or proceeding being made or brought against, or to Nuburu’s knowledge, being threatened
against, Nuburu regarding trademark, trade name, patents, patent rights, copyright, service names, service marks, service mark registrations,
trade secret or other infringement, in each case which could reasonably be expected to have a Nuburu Material Adverse Effect.

 

    15

     

    

 

(ix)             
Environmental Laws. Nuburu (i) is in compliance with any and all applicable foreign, federal, state and local laws and
regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants
or contaminants (“Environmental Laws”), (ii) has received all permits, licenses or other approvals required of them
under applicable Environmental Laws to conduct its businesses and (iii) is in compliance with all terms and conditions of any such permit,
license or approval, except where, in each of the three foregoing clauses, the failure to so comply could not reasonably be expected
to have, individually or in the aggregate, a Material Adverse Effect.

 

(x)               
Title. Nuburu has good and marketable title in fee simple to all real property owned by it and good and marketable title
in all tangible personal property owned by it that is material to its business, in each case free and clear of all liens, encumbrances
and defects (“Liens”) and, except for Liens as do not materially affect the value of such property and do not materially
interfere with the use made and proposed to be made of such property by Nuburu and Liens for the payment of federal, state or other taxes,
the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease by Nuburu are
held by them under valid, subsisting and enforceable leases with which Nuburu is in compliance with such exceptions as are not material
and do not interfere with the use made and proposed to be made of such property and buildings by Nuburu.

 

(xi)             
Insurance. Nuburu is insured by insurers of recognized financial responsibility against such losses and risks and in such
amounts as management of Nuburu believes to be prudent and customary in the businesses in which Nuburu is engaged. Nuburu has not been
refused any insurance coverage sought or applied for and Nuburu has no reason to believe that it will not be able to renew its existing
insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue
its business at a cost that would not materially and adversely affect the condition, financial or otherwise, or the earnings, business
or operations of Nuburu.

 

(xii)           
Regulatory Permits. Nuburu possesses all material certificates, authorizations and permits issued by the appropriate federal,
state or foreign regulatory authorities necessary to conduct its business, and Nuburu has not received any notice of proceedings relating
to the revocation or modification of any such certificate, authorization or permit.

 

(xiii)         
Tax Status. Nuburu has made or filed all federal and state income and all other material tax returns, reports and declarations
required by any jurisdiction to which it is subject and has paid all taxes and other governmental assessments and charges that are material
in amount, shown or determined to be due on such returns, reports and declarations, except those being contested in good faith (but only
to the extent that Nuburu has set aside on its books provisions reasonably adequate for the payment of all unpaid and unreported taxes)
and has set aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent to the periods to which
such returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed in writing to be due by the taxing
authority of any jurisdiction, and to the knowledge of Nuburu there is no basis for any such claim.

 

(xiv)         
Transactions With Affiliates. None of the officers or directors of Nuburu and, to the knowledge of Nuburu, none of the
employees of Nuburu is presently a party to any transaction with Nuburu (other than for services as employees, officers and directors),
including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real
or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge
of Nuburu, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee
or partner, in each case in excess of $120,000 other than for (i) payment of salary or consulting fees for services rendered, (ii) reimbursement
for expenses incurred on behalf of Nuburu and (iii) other employee benefits, including stock option agreements under any stock option
plan of Nuburu.

 

    16

     

    

 

(xv)           
Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction
Documents that will be timely publicly disclosed by Nuburu, Nuburu confirms that neither it nor any other Person acting on its behalf
has provided the Investor or its agents or counsel with any information that it believes constitutes or might constitute material, non-public
information which is not otherwise disclosed in the Registration Statement or the SEC Documents. Nuburu understands and confirms that
the Investor will rely on the foregoing representation in effecting purchases and sales of the Securities. All of the disclosure furnished
by or on behalf of Nuburu to the Investor regarding Nuburu, its business and the transactions contemplated hereby is true and correct
and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements
made therein, in light of the circumstances under which they were made, not misleading. Nuburu acknowledges and agrees that the Investor
neither makes nor has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically
set forth in Section 3 hereof.

 

(xvi)         
Foreign Corrupt Practices. Since January 1, 2018, neither Nuburu, nor to the knowledge of Nuburu, any agent or
other Person acting on behalf of Nuburu, has (i) directly or indirectly, used any funds for unlawful contributions, gifts, entertainment
or other unlawful expenses related to foreign or domestic political activity, (ii) made any unlawful payment to foreign or domestic government
officials or employees or to any foreign or domestic political parties or campaigns from corporate funds, (iii) failed to disclose fully
any contribution made by Nuburu (or made by any Person acting on its behalf of which Nuburu is aware) which is in violation of applicable
anti-bribery/anti-corruption laws, or (iv) violated in any material respect any provision of the Foreign Corrupt Practices Act of 1977,
as amended.

Certain Fees. Except pursuant to the terms of this Agreement, no brokerage or finder’s fees or commissions are or
will be payable by Nuburu to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person
with respect to the transactions contemplated by the Transaction Documents. The Investor shall have no obligation with respect to any
fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section 4(b)(xvi)
that may be due in connection with the transactions contemplated by the Transaction Documents.

 

(xviii)     
Accountants. Nuburu’s financial statements for the fiscal years ended December 31, 2021 and 2020 have been audited
by WithumSmith+Brown, PC and, to the knowledge of Nuburu, such accountants are an independent registered public accounting firm as required
by the Securities Act.

 

(xix)         
No Market Manipulation. Nuburu has not, and to its knowledge no Person acting on its behalf has, (i) taken, directly
or indirectly, any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company
to facilitate the sale or resale of any of the Securities, (ii) sold, bid for, purchased, or, paid any compensation for soliciting
purchases of, any of the Securities, or (iii) paid or agreed to pay to any Person any compensation for soliciting another to purchase
any other securities of the Company.

 

(xx)           
 No Disqualification Events. None of Nuburu, any of its predecessors, any affiliated issuer, any director, executive officer,
other officer of Nuburu participating in the offering contemplated hereby, any beneficial owner of 20% or more of Nuburu’s outstanding
voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in Rule 405 under the Securities
Act) connected with Nuburu in any capacity at the time of sale (each, a “Nuburu Issuer Covered Person”) is subject
to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act (a “Disqualification
Event”), except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3) under the Securities Act. Nuburu has exercised
reasonable care to determine whether any Nuburu Issuer Covered Person is subject to a Disqualification Event.

		5.	COVENANTS.

 

(a)               
Filing of Current Report and Registration Statement. Each of the Company and Nuburu agrees that the Company shall, within
the time required under the Exchange Act, file with the SEC a report on Form 8-K relating to the transactions contemplated by, and describing
the material terms and conditions of, the Transaction Documents (the “Current Report”). The Company shall permit the
Investor to review and comment upon the final pre-filing draft version of the Current Report at least two (2) Business Days prior to
its filing with the SEC and, with respect to information regarding the Investor or the transaction contemplated hereby, the Company shall
not file the Current Report with the SEC in a form to which the Investor reasonably objects. The Investor shall use its reasonable best
efforts to comment upon the final pre-filing draft version of the Current Report within one (1) Business Day from the date the Investor
receives it from the Company. The Company shall also file with the SEC, within thirty (30) days of the date of closing of the Merger,
a new registration statement (as amended or supplemented or replaced with a New Registration Statement, the “Registration Statement”)
covering the resale of the Purchase Shares and all of the Commitment Shares in accordance with the terms of the Registration Rights Agreement
between the Company and the Investor, dated as of the date hereof (the “Registration Rights Agreement”); provided,
however, that the Company may delay filing or suspend the use of any Registration Statement if the Company determines, upon advice of
legal counsel, that in order for the Registration Statement to not contain a material misstatement or omission, an amendment thereto
would be needed.

 

(b)               
Blue Sky. The Company shall take all such action, if any, as is reasonably necessary in order to obtain an exemption for
or to register or qualify (i) the issuance of the Commitment Shares and the sale of the Purchase Shares to the Investor under this Agreement
and (ii) any subsequent resale of all Commitment Shares and all Purchase Shares by the Investor, in each case, under applicable securities
or “Blue Sky” laws of the states of the United States in such states as is reasonably requested by the Investor from time
to time, and shall provide evidence of any such action so taken to the Investor provided, however, that the Company shall not be obligated
to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction
in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not
otherwise so subject”.

 

(c)               
Listing/DTC. The Company shall use its commercially reasonable efforts to promptly secure the listing of all of the Purchase
Shares and Commitment Shares to be issued to the Investor hereunder on the Principal Market (subject to official notice of issuance)
and upon each other national securities exchange or automated quotation system, if any, upon which the Common Stock is then listed, and
shall use commercially reasonable efforts to maintain, so long as any shares of Common Stock shall be so listed, such listing of all
such Securities from time to time issuable hereunder. The Company shall use commercially reasonable efforts to maintain the listing of
the Common Stock on the Principal Market and shall comply in all material respects with the Company’s reporting, filing and other
obligations under the bylaws or rules and regulations of the Principal Market. The Company shall not take any action that would reasonably
be expected to result in the delisting or suspension of the Common Stock on the Principal Market. Following the Closing, the Company
shall promptly, and in no event later than the following Business Day, provide to the Investor copies of any notices it receives from
any Person regarding the continued eligibility of the Common Stock for listing on the Principal Market; provided, however, that the Company
shall not be required to provide the Investor copies of any such notice that the Company reasonably believes constitutes material non-public
information and the Company would not be required to publicly disclose such notice in any report or statement filed with the SEC and
under the Exchange Act or the Securities Act. The Company shall pay all fees and expenses in connection with satisfying its obligations
under this Section 5(c). The Company shall use its commercially reasonable efforts to ensure that its Common Stock can be transferred
electronically as DWAC Shares.

 

    18

     

    

 

(d)               
Prohibition of Short Sales and Hedging Transactions. The Investor agrees that beginning on the date of this Agreement and
ending on the date of termination of this Agreement as provided in Section 11, the Investor and its agents, representatives and
affiliates shall not in any manner whatsoever enter into or effect, directly or indirectly, any (i) “short sale” (as such
term is defined in Rule 200 of Regulation SHO of the Exchange Act) of the SPAC Common Stock or Common Stock, as applicable, or (ii) hedging
transaction, which establishes a net short position with respect to the SPAC Common Stock or Common Stock, as applicable.

 

(e)               
Issuance of Commitment Shares. In consideration for the Investor’s execution and delivery of this Agreement, the
Company shall cause the Transfer Agent to issue shares of Common Stock directly to the Investor in the amounts described below and shall
deliver to the Transfer Agent at the Closing the Irrevocable Transfer Agent Instructions in the form as set forth in Section 6.
The Company shall cause the Commitment Shares (as defined below) to be issued to the Investor as follows: (i) at the Closing, Two Hundred
Thousand (200,000) shares of Common Stock (such shares, the “Initial Commitment Shares”), at $10.00 per share, and
(ii) on the date that is thirty (30) days after the date Closing (the “Additional Commitment Share Delivery Date”),
a number of shares equal to Two Million Dollars ($2,000,000) divided by the lesser of (x) $10.00 per share or (y) the average closing
price of the Common Stock for the ten (10) consecutive business days prior to the date that is 30 days after the closing of the Merger,
provided that if such average closing price is below $5.00 per share, then the average closing price shall be deemed to be $5.00 per
share (such shares, the “Additional Commitment Shares” and, together with the Initial Commitment Shares, the “Commitment
Shares”). For the avoidance of doubt, the Commitment Shares shall be fully earned and deemed fully paid for as of the date
of this Agreement, irrespective of any subsequent termination of this Agreement (except a termination by Investor pursuant to Section
11(b)).

 

(f)                
Due Diligence; Non-Public Information. The Investor shall have the right, from time to time as the Investor may reasonably
deem appropriate and upon reasonable advance notice to the Company and Nuburu, to perform reasonable due diligence on the Company and
Nuburu during normal business hours. Each of the Company and Nuburu and their respective officers and employees shall provide information
and reasonably cooperate with the Investor in connection with any reasonable request by the Investor related to the Investor’s
due diligence of the Company and Nuburu. Each party hereto agrees not to disclose any Confidential Information of the other party to
any third party and shall not use the Confidential Information for any purpose other than in connection with, or in furtherance of, the
transactions contemplated hereby. Each party hereto acknowledges that the Confidential Information shall remain the property of the disclosing
party and agrees that it shall take all reasonable measures to protect the secrecy of any Confidential Information disclosed by the other
party. Each of the Company and Nuburu confirms that neither it nor any other Person acting on its behalf shall provide the Investor or
its agents or counsel with any information that constitutes or might constitute material, non-public information, unless a simultaneous
public announcement thereof is made by the Company in the manner contemplated by Regulation FD. In the event of a breach of the foregoing
covenant by the Company, Nuburu or any Person acting on their behalf (as determined in the reasonable good faith judgment of the Investor),
in addition to any other remedy provided herein or in the other Transaction Documents, if the Investor is holding any Securities at the
time of the disclosure of material, non-public information, the Investor shall have the right to make a public disclosure, in the form
of a press release, public advertisement or otherwise, of such material, non-public information without the prior approval by the Company
and Nuburu; provided the Investor shall have first provided notice to the Company and Nuburu that it believes it has received information
that constitutes material, non-public information, the Company and Nuburu shall have at least two (2) Business Days to either (i) demonstrate
that such information is not material non-public information to the reasonable satisfaction of the Investor or (ii) publicly disclose
such material, non-public information prior to any such disclosure by the Investor. The Investor shall not have any liability to the
Company, any of its Subsidiaries, Nuburu, or any of their respective directors, officers, employees, stockholders, shareholders, or agents,
for any such disclosure. Each of the Company and Nuburu understands and confirms that the Investor shall be relying on the foregoing
covenants in effecting transactions in securities of the Company.

 

    19

     

    

 

(g)               
Purchase Records. The Investor and the Company shall each maintain records showing the remaining Available Amount at any
given time and the dates and Purchase Amounts for each Regular Purchase, Accelerated Purchase and Additional Accelerated Purchase or
shall use such other method, reasonably satisfactory to the Investor and the Company.

 

(h)               
Taxes. The Company shall pay any and all transfer, stamp or similar taxes that may be payable with respect to the issuance
and delivery of any shares of Common Stock to the Investor made under this Agreement. For the avoidance of doubt, any other taxes incurred
by the Investor (including any taxes on income resulting from the transactions contemplated by this Agreement) shall solely be the responsibility
of the Investor.

 

(i)                
Aggregation. From and after the date of this Agreement, neither the Company, nor any of its affiliates will, and the
Company shall use its reasonable best efforts to ensure that no Person acting on their behalf will, directly or indirectly, make any
offers or sales of any security or solicit any offers to purchase any security, under circumstances that would cause this offering of
the Securities by the Company to the Investor to be aggregated with other offerings by the Company in a manner that would require stockholder
approval pursuant to the rules of the Principal Market on which any of the securities of the Company are listed or designated, unless
stockholder approval is obtained before the closing of such subsequent transaction in accordance with the rules of such Principal Market.

 

(j)                
Use of Proceeds. The Company will use the net proceeds from the offering for any corporate purpose at the sole discretion
of the Company.

 

(k)               
Other Transactions. During the term of this Agreement, neither Company nor Nuburu shall enter into, announce or recommend
to its stockholders any agreement, plan, arrangement or transaction in or of which the terms thereof would restrict, materially delay,
conflict with or impair the ability or right of the Company to perform its obligations under the Transaction Documents, including, without
limitation, the obligation of the Company or Nuburu to deliver the Purchase Shares and the Commitment Shares to the Investor in accordance
with the terms of the Transaction Documents.

 

(l)                
Integration. From and after the date of this Agreement, neither the Company nor Nuburu, nor or any of their respective
affiliates will, and each of the Company and Nuburu shall use its reasonable best efforts to ensure that no Person acting on their behalf
will, directly or indirectly, make any offers or sales of any security or solicit any offers to purchase any security, under circumstances
that would require registration of the offer and sale of any of the Securities under the Securities Act.

 

(m)             
Limitation on Variable Rate Transactions. From the date of this Agreement and for a period of 48 months thereafter, the
Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries
of Common Stock involving a Variable Rate Transaction other than with the Investor. “Variable Rate Transaction” means
an “equity line of credit” or substantially similar transaction whereby an investor is irrevocably bound to purchase securities
over a period of time from the Company at a price based on the market price of the Company’s Common Stock at the time of each such
purchase, provided, however, that this Section 5m shall not be deemed to prohibit the issuance and sale of Common Stock pursuant
to an “at-the-market offering” by the Company exclusively through a registered broker-dealer acting as agent of the Company
pursuant to a written agreement between the Company and such registered broker-dealer.

to the Investor that, while the Agreement is effective, no instruction other than the Irrevocable Initial Transfer Agent Instructions
referred to in this Section 6 will be given by the Company to the Transfer Agent with respect to the Initial Commitment Shares,
and the Initial Commitment Shares shall otherwise be freely transferable on the books and records of the Company.

All Commitment Shares to be issued to or for the benefit of the Investor pursuant to this Agreement shall be issued as DWAC Shares. The

		9.	INDEMNIFICATION.

 

(a)               
In consideration of the Investor’s execution and delivery of the Transaction Documents and acquiring the Securities hereunder
and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify
and hold harmless the Investor and all of its affiliates, stockholders, officers, directors, members, managers, employees and direct
or indirect investors and any of the foregoing Person’s agents or other representatives (including, without limitation, those retained
in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against
any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and reasonable expenses
in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is
sought), and including reasonable and documented out-of-pocket attorneys’ fees and disbursements (the “Indemnified Liabilities”),
actually incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation
or warranty made by the Company in the Transaction Documents or any other certificate, instrument or document executed by the Company
contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents
or any other certificate, instrument or document contemplated hereby or thereby, or (c) any cause of action, suit or claim brought or
made against such Indemnitee and arising out of or resulting from the execution, delivery, performance or enforcement of the Transaction
Documents or any other certificate, instrument or document contemplated hereby or thereby, other than, in the case of clause (c), with
respect to Indemnified Liabilities which result directly and primarily from the fraud, gross negligence, bad faith or willful misconduct
of an Indemnitee. The indemnity in this Section 9(a) shall not apply to amounts paid in settlement of any claim if such settlement
is effected without the prior written consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed.
To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution
to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. Payment under this
indemnification shall be made within thirty (30) days from the date the Investor makes written request for it. A certificate containing
reasonable detail as to the amount of such indemnification submitted to the Company by the Investor shall be conclusive evidence, absent
manifest error, of the amount due from the Company to the Investor; provided that the Indemnitee shall undertake to repay any amounts
paid to it hereunder if it is ultimately determined, by a final and non-appealable order of a court of competent jurisdiction, that the
Indemnitee is not entitled to be indemnified against such Indemnified Liabilities by the Company pursuant to this Agreement. If any action
shall be brought against any Indemnitee in respect of which indemnity may be sought pursuant to this Agreement, such Indemnitee shall
promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing
reasonably acceptable to the Indemnitee. Any Indemnitee shall have the right to employ separate counsel in any such action and participate
in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnitee, except to the extent that
(i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable
period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate
counsel, a material conflict on any material issue between the position of the Company and the position of such Indemnitee, in which
case the Company shall be responsible for the reasonable and documented out-of-pocket fees and expenses of no more than one such separate
counsel. Notwithstanding anything in the foregoing to the contrary, the Investor acknowledges and agrees that no Indemnitee shall make
any claim or proceed against the trust account (the “Trust Account”) established by the Company, including by way of set-off,
and shall not be entitled to any funds in the Trust Account under any circumstance. In the event that any Indemnitee has a claim against
the Company under this Agreement, it will pursue such claim solely against the Company and not against the property held in the Trust
Account.

 

(b)               
In consideration of the Investor’s execution and delivery of the Transaction Documents and acquiring the Securities hereunder
and in addition to all of Nuburu’s other obligations under the Transaction Documents, Nuburu shall defend, protect, indemnify and
hold harmless the Investor and all of its Indemnitees from and against any and all Indemnified Liabilities, actually incurred by any
Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made
by Nuburu in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach
of any covenant, agreement or obligation of Nuburu contained in the Transaction Documents or any other certificate, instrument or document
executed by Nuburu contemplated hereby or thereby, or (c) any cause of action, suit or claim brought or made against such Indemnitee
and arising out of or resulting from the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate,
instrument or document contemplated hereby or thereby, other than, in the case of clause (c), with respect to Indemnified Liabilities
which result from the fraud, gross negligence, bad faith or willful misconduct of an Indemnitee. The indemnity in this Section 9(b)
shall not apply to amounts paid in settlement of any claim if such settlement is effected without the prior written consent of Nuburu,
which consent shall not be unreasonably withheld, conditioned or delayed. To the extent that the foregoing undertaking by Nuburu may
be unenforceable for any reason, Nuburu shall make the maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law. Payment under this indemnification shall be made within thirty (30) days from
the date Investor makes written request for it. A certificate containing reasonable detail as to the amount of such indemnification submitted
to Nuburu by the Investor shall be conclusive evidence, absent manifest error, of the amount due from Nuburu to the Investor; provided
that the Indemnitee shall undertake to repay any amounts paid to it hereunder if it is ultimately determined, by a final and non-appealable
order of a court of competent jurisdiction, that the Indemnitee is not entitled to be indemnified against such Indemnified Liabilities
by Nuburu pursuant to this Agreement. If any action shall be brought against any Indemnitee in respect of which indemnity may be sought
pursuant to this Agreement, such Indemnitee shall promptly notify Nuburu in writing, and Nuburu shall have the right to assume the defense
thereof with counsel of its own choosing reasonably acceptable to the Indemnitee. Any Indemnitee shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense
of such Indemnitee, except to the extent that (i) the employment thereof has been specifically authorized by Nuburu in writing,
(ii) Nuburu has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action
there is, in the reasonable opinion of such separate counsel, a material conflict on any material issue between the position of Nuburu
and the position of such Indemnitee, in which case Nuburu shall be responsible for the reasonable and documented out-of-pocket fees and
expenses of no more than one such separate counsel. Notwithstanding the foregoing, any indemnification provided by the Company and Nuburu
shall be netted against each other so as not to result in duplicate recoveries for the same Losses

 

    25

of a breach of a covenant which is reasonably curable, only if such breach continues for a period of at least five (5) Business Days;

prior written consent of the Investor, including by merger or consolidation. The Investor may not assign its rights or obligations under

No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted
successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

 

(i)                
Publicity. Each of the Company and Nuburu shall afford the Investor and its counsel with the opportunity to review and
comment upon, shall consult with the Investor and its counsel on the form and substance of, and shall give due consideration to all such
comments from the Investor or its counsel on, any press release, SEC filing, or any other public disclosure by or on behalf of the Company

if the form and substance of such press release, SEC filing, or other public disclosure relating to the Investor, its purchases hereunder
or any aspect of the Transaction Documents or the transactions contemplated thereby previously have been publicly disclosed by the Company
in compliance with this Section 12(i).

 

    31

     

    

 

(j)                
Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things,
and shall execute and deliver all such other agreements, certificates, instruments and documents, as the other party may reasonably request
in order to consummate and make effective, as soon as reasonably possible, the Commencement, and to carry out the intent and accomplish
the purposes of this Agreement and the consummation of the transactions contemplated hereby.

 

(k)               
No Financial Advisor, Placement Agent, Broker or Finder. Each of the Company and Nuburu represents and warrants
to the Investor that, it has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions
contemplated hereby. The Investor represents and warrants to the Company and Nuburu that it has not engaged any financial advisor, placement
agent, broker or finder in connection with the transactions contemplated hereby. Each of the Company and Nuburu shall be responsible
for the payment of any fees or commissions, if any, of any financial advisor, placement agent, broker or finder engaged by it relating
to or arising out of the transactions contemplated hereby. Each of the Company and Nuburu shall pay, and hold the Investor harmless against,
any liability, loss or expense (including, without limitation, reasonable attorneys’ fees and out of pocket expenses) arising in
connection with any such claim.

 

(l)                
No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to
express their mutual intent, and no rules of strict construction will be applied against any party.

 

(m)             
Remedies, Other Obligations, Breaches and Injunctive Relief. The Investor’s remedies provided in this
Agreement, including, without limitation, the Investor’s remedies provided in Section 9, shall be cumulative and in addition to
all other remedies available to the Investor under this Agreement, at law or in equity (including a decree of specific performance and/or
other injunctive relief), no remedy of the Investor contained herein shall be deemed a waiver of compliance with the provisions giving
rise to such remedy and nothing herein shall limit the Investor’s right to pursue actual damages for any failure by the Company
to comply with the terms of this Agreement. Each of the Company and Nuburu acknowledges that a breach by it of its obligations hereunder
will cause irreparable harm to the Investor and that the remedy at law for any such breach may be inadequate. Each of the Company and
Nuburu therefore agrees that, in the event of any such breach or threatened breach, the Investor shall be entitled, in addition to all
other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond
or other security being required.

 

(n)               
Enforcement Costs. If: (i) this Agreement is placed by the Investor in the hands of an attorney for enforcement or is enforced
by the Investor through any legal proceeding; (ii) an attorney is retained to represent the Investor in any bankruptcy, reorganization,
receivership or other proceedings affecting creditors’ rights and involving a claim under this Agreement; or (iii) an attorney
is retained to represent the Investor in any other proceedings whatsoever in connection with this Agreement, then Company and Nuburu,
severally and not jointly, shall pay to the Investor, as incurred by the Investor, all reasonable costs and expenses including reasonable
attorneys’ fees incurred in connection therewith, in addition to all other amounts due hereunder.

 

(o)               
Amendment and Waiver; Failure or Indulgence Not Waiver. No provision of this Agreement may be amended or waived by the
parties from and after the date that is one (1) Business Day immediately preceding the filing of the Registration Statement with the
SEC. Subject to the immediately preceding sentence, (i) no provision of this Agreement may be amended other than by a written instrument
signed by both parties hereto and (ii) no provision of this Agreement may be waived other than in a written instrument signed by the
party against whom enforcement of such waiver is sought. No failure or delay in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other right, power or privilege.

 

(p)               
Adjustments for Share Splits. The parties acknowledge and agree that all share-related numbers contained in this Agreement
shall be adjusted to take into account any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other
similar transaction effected with respect to the SPAC Common Stock or Common Stock, as applicable, except as specifically stated herein
and without any duplication.

REGISTRATION RIGHTS AGREEMENT

 

This REGISTRATION RIGHTS
AGREEMENT (this “Agreement”), dated as of August 5, 2022, is made by and among TAILWIND ACQUISITION
CORP., a Delaware corporation (the “Company”), NUBURU, INC., a Delaware corporation (“Nuburu”),
and LINCOLN PARK CAPITAL FUND, LLC, an Illinois limited liability

defined herein shall have the respective meanings set forth in the Purchase Agreement by and among the parties hereto, dated as of the
date hereof (as amended, restated, supplemented or otherwise modified from time to time, the “Purchase Agreement”).

 

WHEREAS:

 

Pursuant to that certain
Business Combination Agreement, dated as of August 5, 2022 (as may be amended, modified, restated or supplemented from time
to time, the “Business Combination Agreement”), by and among the Company, Nuburu, and Compass Merger Sub, Inc., a
wholly owned subsidiary of the Company (“Merger Sub”), the Company and Nuburu intend to effect a merger of Merger
Sub with and into Nuburu (the “Merger”) and, upon consummation of the Merger (the “Closing”), Merger
Sub will cease to exist and Nuburu will become a wholly owned subsidiary of the Company;

 

In connection with the Closing,
the Company’s name shall be changed from “Tailwind Acquisition Corp.” to “Nuburu, Inc.” and Nuburu’s
name shall be changed from “Nuburu, Inc.” to “Nuburu Subsidiary, Inc.”; and

 

From and after the Closing,
and subject to the terms and conditions set forth in the Purchase Agreement, the Company wishes to sell to the Investor, and the Investor
wishes to buy from the Company, up to one hundred million dollars ($100,000,000) of Purchase Shares, and to induce the Buyer to enter
into the Purchase Agreement, the Company has agreed to provide certain registration rights under the Securities Act of 1933, as amended,
and the rules and regulations thereunder (collectively, the “Securities Act”), and applicable state securities laws.

 

NOW, THEREFORE, in
consideration of the promises and the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the Company and the Buyer hereby agree as follows:

 

1.             DEFINITIONS.

 

As used in this Agreement,
the following terms shall have the following meanings:

 

(a)               
“Investor” means the Buyer, any transferee or assignee thereof to whom the Buyer assigns its rights under this
Agreement in accordance with Section 9 and who agrees to become bound by the provisions of this Agreement, and any transferee or assignee
thereof to whom a transferee or assignee assigns its rights under this Agreement in accordance with Section 9 and who agrees to become
bound by the provisions of this Agreement.

 

(b)               
“Person” means any individual or entity including but not limited to any corporation, a limited liability company,
an exempted company, an association, a partnership, an exempted partnership, an organization, a business, an individual, a governmental
or political subdivision thereof or a governmental agency.

 

(c)               
“Register,” “registered,” and “registration” refer to a registration
effected by preparing and filing one or more registration statements of the Company in compliance with the Securities Act and pursuant
to Rule 415 under the Securities Act or any successor rule providing for offering securities on a continuous basis (“Rule 415”),
and the declaration or ordering of effectiveness of such registration statement(s) by the United States Securities and Exchange Commission
(the “SEC”).

 

     

     

    

 

(d)               
“Registrable Securities” means all of the Commitment Shares and all of the Purchase Shares that may, from time
to time, be issued or become issuable to the Investor under the Purchase Agreement (without regard to any limitation or restriction on
purchases), and any and all shares of capital stock issued or issuable with respect to the Purchase Shares or the Commitment Shares or
the Purchase Agreement as a result of any stock split, reverse stock split, share dividend, recapitalization, exchange or similar event
or otherwise, without regard to any limitation on purchases under the Purchase Agreement.

 

(e)               
“Registration Statement” means one or more registration statements of the Company covering only the sale of
the Registrable Securities.

 

2.             REGISTRATION.

 

(a)               
Mandatory Registration. The Company shall, within thirty (30) days following the Closing, file with the SEC an initial
Registration Statement covering the maximum number of Registrable Securities as shall be permitted to be included thereon in accordance
with applicable SEC rules, regulations and interpretations so as to permit the resale of such Registrable Securities by the Investor
under Rule 415 under the Securities Act at then prevailing market prices (and not fixed prices), as mutually determined by both the Company
and the Investor in consultation with their respective legal counsel, subject to the aggregate number of authorized shares of the Company’s
Common Stock then available for issuance in its Amended and Restated Certificate of Incorporation and the Exchange Cap (as defined in
the Purchase Agreement); provided, however, that the Company may delay filing or suspend the use of any Registration Statement
if the Company determines, upon advice of legal counsel, that in order for the registration statement to not contain a material misstatement
or omission, an amendment thereto would be needed. The initial Registration Statement shall register only the Registrable Securities.
The Investor and its counsel shall have a reasonable opportunity to review and comment upon such Registration Statement and any amendment
or supplement to such Registration Statement and any related prospectus prior to its filing with the SEC, and the Company shall give
due consideration to all such comments. The Investor shall furnish all information reasonably requested by the Company for inclusion
therein. The Company shall use its commercially reasonable efforts to have the Registration Statement and any amendment declared effective
by the SEC at the earliest possible date. The Company shall use commercially reasonable efforts to keep the Registration Statement effective
pursuant to Rule 415 promulgated under the Securities Act and available for the resale by the Investor of all of the Registrable Securities
covered thereby at all times until the earlier of (i) the date on which the Investor shall have resold all the Registrable Securities
covered thereby and no Available Amount remains under the Purchase Agreement, (ii) such Registrable Securities may be sold without registration
pursuant to Rule 144 (as defined below) without limitation as to volume and manner of sale restrictions and no Available Amount remains
under the Purchase Agreement, (iii) six months after the termination of the Purchase Agreement, and (iv) one year after the date on which
no Available Amount remains under the Purchase Agreement (the “Registration Period”). The Registration Statement (including
any amendments or supplements thereto and prospectuses contained therein) shall not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances
in which they were made, not misleading.

 

(b)               
Rule 424 Prospectus. The Company shall, as required by applicable securities regulations, from time to time file with the
SEC, pursuant to Rule 424 promulgated under the Securities Act, the prospectus and prospectus supplements, if any, to be used in connection
with sales of the Registrable Securities under the Registration Statement. The Investor and its counsel shall have a reasonable opportunity
to review and comment upon such prospectus prior to its filing with the SEC, and the Company shall give due consideration to all such
comments; provided that the Company shall not be required to provide, and the Investor shall not have an opportunity to review,
any prospectus supplement filed solely to include in the Registration statement, from time to time, documents filed with, or furnished
to, the SEC by the Company under the Exchange Act (as defined below). The Investor shall use its commercially reasonable efforts to comment
upon such prospectus within one (1) Business Day from the date the Investor receives the substantially final pre-filing version of such
prospectus.

 

     2

     

    

 

(c)               
Sufficient Number of Shares Registered. In the event the number of shares available under the Registration Statement is
insufficient to cover all of the Registrable Securities, the Company shall amend the Registration Statement or file a new Registration
Statement (a “New Registration Statement”), so as to cover all of such Registrable Securities (subject to the limitations
set forth in Section 2(a)) as soon as practicable, but in any event not later than ten (10) Business Days after the necessity therefor
arises, subject to any limits that may be imposed by the SEC pursuant to Rule 415 under the Securities Act. The Company shall use its
commercially reasonable efforts to cause such amendment and/or New Registration Statement to become effective as soon as practicable
following the filing thereof.

 

(d)               
Offering. If the staff of the SEC (the “Staff”) or the SEC seeks to characterize any offering pursuant
to a Registration Statement filed pursuant to this Agreement as constituting an offering of securities that does not permit such Registration
Statement to become effective and be used for resales by the Investor under Rule 415 at then-prevailing market prices (and not fixed
prices), or if after the filing of the initial Registration Statement with the SEC pursuant to Section 2(a), the Company is otherwise
required by the Staff or the SEC to reduce the number of Registrable Securities included in such initial Registration Statement, then
the Company shall reduce the number of Registrable Securities to be included in such initial Registration Statement (with the prior consent,
which shall not be unreasonably withheld, of the Investor as to the specific Registrable Securities to be removed therefrom) until such
time as the Staff and the SEC shall so permit such Registration Statement to become effective and be used as aforesaid. In the event
of any reduction in Registrable Securities pursuant to this paragraph, the Company shall file one or more New Registration Statements
in accordance with Section 2(c) until such time as all Registrable Securities have been included in Registration Statements that have
been declared effective and the prospectus contained therein is available for use by the Investor. Notwithstanding any provision herein
or in the Purchase Agreement to the contrary, the Company’s obligations to register Registrable Securities (and any related conditions
to the Investor’s obligations) shall be qualified as necessary to comport with any requirement of the SEC or the Staff as addressed
in this Section 2(d).

 

3.             RELATED
OBLIGATIONS.

 

With respect to the Registration
Statement and whenever any Registrable Securities are to be registered pursuant to Section 2 including on any New Registration Statement,
the Company shall use its commercially reasonable efforts to effect the registration of the Registrable Securities in accordance with
the intended method of disposition thereof and, pursuant thereto, the Company shall have the following obligations:

 

(a)               
The Company shall prepare and file with the SEC such amendments (including post-effective amendments) and supplements to any Registration
Statement and the prospectus used in connection with such Registration Statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the Securities Act, as may be necessary to keep the Registration Statement or any New Registration Statement effective
at all times during the Registration Period, and, during such period, comply with the provisions of the Securities Act in connection
with the offer, issuance and sale of the Registrable Securities.

 

     3

     

    

 

(b)               
The Company shall permit the Investor to review and comment upon the final prefiling draft version of the Registration Statement
or any New Registration Statement and any amendments or supplements thereto at least two (2) Business Days prior to its filing with the
SEC and, with respect to information regarding the Investor or the transaction contemplated hereby, the Company shall not file the Registration
Statement or any New Registration Statement and any amendments or supplements thereto with the SEC in a form to which the Investor reasonably
objects. The Investor shall use its commercially reasonable efforts to comment upon the Registration Statement or any New Registration
Statement and any amendments or supplements thereto within two (2) Business Days from the date the Investor receives the final version
thereof. The Company shall furnish to the Investor, without charge, any correspondence from the SEC or the staff of the SEC to the Company
or its representatives relating to the Registration Statement or any New Registration Statement.

 

(c)               
Upon request of the Investor, the Company shall furnish to the Investor, (i) promptly after the same is prepared and filed with
the SEC, at least one copy of such Registration Statement and any amendment(s) thereto, including financial statements and schedules,
all documents incorporated therein by reference and all exhibits, (ii) upon the effectiveness of any Registration Statement, a copy of
the prospectus included in such Registration Statement and all amendments and supplements thereto (or such other number of copies as
the Investor may reasonably request) and (iii) such other documents, including copies of any preliminary or final prospectus, as the
Investor may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by the Investor.
For the avoidance of doubt, any filing available to the Investor via the SEC’s live EDGAR system shall be deemed “furnished
to the Investor” hereunder.

 

(d)               
Upon the request of the Investor, the Company shall use commercially reasonable efforts to (i) register and qualify the resale
by the Investor of the Registrable Securities covered by a Registration Statement under such other securities or “blue sky”
laws of such jurisdictions in the United States as the Investor reasonably requests, (ii) prepare and file in those jurisdictions, such
amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain
the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations
and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable
to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be
required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise
be required to qualify but for this Section 3(d), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general
consent to service of process in any such jurisdiction. The Company shall promptly notify the Investor who holds Registrable Securities
of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable
Securities for sale under the securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual
notice of the initiation or threatening of any proceeding for such purpose.

 

(e)               
As promptly as practicable after becoming aware of such event or facts, the Company shall notify the Investor in writing of the
happening of any event or existence of such facts as a result of which the prospectus included in any Registration Statement, as then
in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they were made, not misleading (provided that in no
event shall such notice contain any material, non-public information regarding the Company), and promptly prepare a supplement or amendment
to such Registration Statement to correct such untrue statement or omission, and deliver a copy of such supplement or amendment to the
Investor (or such other number of copies as the Investor may reasonably request), provided, however, that the Company may
delay filing such supplement or amendment if the Company, upon advice of legal counsel, reasonably believes that such filing or use could
materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of information
that could materially adversely affect the Company. The Company shall also promptly notify the Investor in writing (i) when a prospectus
or any prospectus supplement or post-effective amendment has been filed, and when a Registration Statement or any post-effective amendment
has become effective (notification of such effectiveness shall be delivered to the Investor by email or facsimile on the same day of
such effectiveness), (ii) of any request by the SEC for amendments or supplements to any Registration Statement or related prospectus
or related information, and (iii) of the Company’s reasonable determination that a post-effective amendment to a Registration Statement
would be appropriate.

 

     4

     

    

 

(f)                
The Company shall use its commercially reasonable efforts to prevent the issuance of any stop order or other suspension of effectiveness
of any registration statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and,
if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to
notify the Investor of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.

 

(g)               
The Company shall (i) cause all the Registrable Securities to be listed on each securities exchange on which securities of the
same class or series issued by the Company are then listed, if any, if the listing of such Registrable Securities is then permitted under
the rules of such exchange, or (ii) secure designation and quotation of all the Registrable Securities on the Principal Market. The Company
shall pay all fees and expenses in connection with satisfying its obligation under this Section 3.

 

(h)               
The Company shall cooperate with the Investor to facilitate the timely preparation and delivery of certificates or book-entry
confirmations (in each case not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to any
registration statement and enable such certificates or book-entry confirmations to be in such denominations or amounts as the Investor
may reasonably request and registered in such names as the Investor may request.

 

(i)                
The Company shall at all times provide a transfer agent and registrar with respect to its Common Stock.

 

(j)                
If reasonably requested in writing by the Investor, the Company shall (i) as soon as practicable after receipt of written notice
from the Investor, incorporate in a prospectus supplement or post-effective amendment such information as the Investor reasonably requests
be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with
respect to the number of Registrable Securities being sold, the purchase price being paid therefor and any other terms of the offering
of the Registrable Securities; (ii) make all required filings of such prospectus supplement or post-effective amendment as soon as practicable
upon notification of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) supplement or
make amendments to any Registration Statement or New Registration Statement.

 

(k)               
The Company shall use its commercially reasonable efforts to cause the Registrable Securities covered by any Registration Statement
to be registered with or approved by such other governmental agencies or authorities as may be necessary to consummate the disposition
of such Registrable Securities.

(l)                
Within one (1) Business Day after any Registration Statement which includes the Registrable Securities is declared effective by
the SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the Transfer Agent for such Registrable
Securities (with copies to the Investor) confirmation that such Registration Statement has been declared effective by the SEC in the
form attached hereto as Exhibit A, or such other form acceptable to the Company’s Transfer Agent. Thereafter, if requested
by the Investor at any time, the Company shall require its counsel to deliver to the Investor a written confirmation as to whether the
Registration Statement has been declared effective under the Securities Act and whether, to its knowledge, a stop order suspending the
effectiveness of the Registration Statement has been issued or threatened by the SEC.

 

(m)             
The Company shall take all other reasonable actions necessary to expedite and facilitate disposition by the Investor of Registrable
Securities pursuant to any Registration Statement.

 

     5

     

    

 

4.             OBLIGATIONS
OF THE INVESTOR.

 

(a)               
The Company shall notify the Investor in writing of the information the Company reasonably requires from the Investor in connection
with any Registration Statement hereunder. The Investor shall as soon as practicable furnish to the Company such information regarding
itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with
such registration as the Company may reasonably request.

 

(b)               
The Investor agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and
filing of any Registration Statement hereunder and any amendments and supplements thereto.

 

(c)               
The Investor agrees that, upon receipt of any notice from the Company of the happening of any event or existence of facts of the
kind described in Section 3(f) or the first sentence of Section 3(e), the Investor will immediately discontinue disposition of Registrable
Securities pursuant to any Registration Statement(s) covering such Registrable Securities until the Investor’s receipt of copies
of a notice regarding the resolution or withdrawal of the stop order or suspension as contemplated by Section 3(f) or of the supplemented
or amended prospectus contemplated by Section 3(f) or the first sentence of 3(e). Notwithstanding anything to the contrary, the Company
shall cause its Transfer Agent to promptly deliver shares of Common Stock without any restrictive legend in accordance with the terms
of the Purchase Agreement in connection with any sale of Registrable Securities with respect to which the Investor has entered into a
contract for sale prior to the Investor’s receipt of a notice from the Company of the happening of any event of the kind described
in Section 3(f) or the first sentence of Section 3(e) and for which the Investor has not yet settled.

 

5.             EXPENSES OF REGISTRATION.

 

All reasonable expenses, other
than sales or brokerage commissions and fees incurred in connection with its sale of the Registrable Securities, including the fees and
disbursement of counsel for the Investor, incurred in connection with registrations, filings or qualifications pursuant to Section 2
and Section 3, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, and fees
and disbursements of counsel for the Company, shall be paid by the Company.

 

     6

     

    

 

6.             INDEMNIFICATION.

 

(a)               
To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend the Investor, each
Person, if any, who controls the Investor, the members, the directors, officers, partners, employees, agents, members, managers representatives
of the Investor and each Person, if any, who controls the Investor within the meaning of the Securities Act or the Securities Exchange
Act of 1934, as amended (the “Exchange Act”) (each, an “Indemnified Person”), against any losses,
claims, damages, liabilities, judgments, fines, penalties, charges, costs, attorneys’ fees, amounts paid in settlement or expenses,
joint or several, (collectively, “Claims”) incurred in investigating, preparing or defending any action, claim, suit,
inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other
regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto (“Indemnified
Damages”), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or
threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact
in the Registration Statement, any New Registration Statement or any post-effective amendment thereto, or the omission or alleged omission
to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement
or alleged untrue statement of a material fact contained in the final prospectus (as amended or supplemented, if the Company files any
amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary
to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading or (iii)
any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any other law, including, without limitation,
any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to
the Registration Statement or any New Registration Statement (the matters in the foregoing clauses (i) through (iii) being, collectively,
 “Violations”). The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are
due and payable, for any reasonable, documented out-of-pocket legal fees or other reasonable, documented out-of-pocket expenses incurred
by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising out of or based
upon a Violation which occurs in reliance upon and in conformity with information about the Investor furnished in writing to the Company
by any Indemnified Person expressly for use in connection with the preparation of the Registration Statement, any New Registration Statement
or any such amendment thereof or supplement thereto or prospectus contained therein, if such Registration Statement, New Registration
Statement or amendment thereof or supplement thereto or prospectus contained therein was timely made available by the Company pursuant
to Section 3(c) or Section 3(e); (ii) with respect to any superseded prospectus, shall not inure to the benefit of any Indemnified Person
from whom the Indemnified Person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the
benefit of any Indemnified Person controlling such Indemnified Person) if the untrue statement or omission of material fact contained
in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, if such revised prospectus was
timely made available by the Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was promptly advised in writing
not to use the incorrect prospectus prior to the use giving rise to a violation and such Indemnified Person, notwithstanding such advice,
used it; (iii) shall not be available to the extent such Claim is based on a failure of the Investor to deliver or cause to be delivered
the prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 3(c) or
Section 3(e); (iv) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written
consent of the Company, which consent shall not be unreasonably withheld; and (v) shall not apply if and to the extent any Claim arises
due to the gross negligence, fraud or willful misconduct of any Indemnified Person, as determined by a court of competent jurisdiction.
Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and
shall survive the transfer of the Registrable Securities by the Investor pursuant to Section 9. Notwithstanding anything to the contrary
in the foregoing, the Investor acknowledges and agrees that no Indemnified Person shall make a claim or proceed against the Trust Account,
including by way of set-off, and shall not be entitled to any funds in the Trust Account under any circumstance. In the event that any
Indemnified Person has a claim against the Company under this Agreement, it will pursue such claim solely against the Company and not
against the property held in the Trust Account.

 

     7

     

    

 

(b)               
 In connection with the Registration Statement or any New Registration Statement, the Investor agrees to indemnify, hold harmless
and defend, to the same extent and in the same manner as is set forth in Section 6(a), the Company, each of its directors, each of its
officers who signs the Registration Statement or any New Registration Statement, each Person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act (collectively and together with an Indemnified Person, an “Indemnified
Party”), against any Claim or Indemnified Damages to which any of them may become subject, under the Securities Act, the Exchange
Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation (which, in the case of this
Section 6(b) shall include the failure on the part of the Investor to deliver a prospectus as required by this Agreement and applicable
law), in each case to the extent, and only to the extent, that such Violation occurs in reliance upon and in conformity with written
information about the Investor set forth on Exhibit B attached hereto and furnished to the Company by the Investor expressly for use
in connection with such Registration Statement (it being hereby acknowledged and agreed that such written information, as the same shall
be updated from time to time in writing by the Investor, in connection with the filing of a Registration Statement or any New Registration
Statement (including any amendments or supplements thereto and prospectuses contained therein) to set forth the number of shares of Common
Stock then beneficially owned, is the only written information furnished to the Company by or on behalf of the Investor expressly for
use in any Registration Statement); and, subject to Section 6(d), the Investor will reimburse any reasonable documented and out-of-pocket
legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim; provided, however,
that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall
not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Investor,
which consent shall not be unreasonably withheld; provided, further, that the Investor shall be liable under this Section
6(b) for only that amount of a Claim or Indemnified Damages as does not exceed the net proceeds to the Investor as a result of the sale
of Registrable Securities pursuant to such Registration Statement. Such indemnity shall remain in full force and effect regardless of
any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the
Investor pursuant to Section 9.

 

(c)               
Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding) involving a Claim, such Indemnified Person or Indemnified Party
shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party
a written notice of the commencement thereof, and the indemnifying party shall have the right to participate in, and, to the extent the
indemnifying party so desires, jointly with any other indemnifying party similarly notified, to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified Person or the Indemnified Party, as the case may be;
provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with
the fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party,
the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due
to actual or potential differing interests between such Indemnified Person or Indemnified Party and any other party represented by such
counsel in such proceeding. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be
obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to
such claim, unless in the reasonable judgment, with advice of counsel, of any Indemnified Person or Indemnified Party, a conflict of
interest may exist between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding.
The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense
of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available
to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified
Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto.
No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided,
however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall,
without the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or
other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified
Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided
for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to
all third parties, firms or corporations relating to the matter for which indemnification has been made. The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying
party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying
party is prejudiced in its ability to defend such action.

 

     8

     

    

 

(d)               
The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages are incurred.

 

(e)               
The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar right of the Indemnified
Party or Indemnified Person against the indemnifying party or others, and (ii) any liabilities the indemnifying party may be subject
to pursuant to law.

 

7.             CONTRIBUTION.

 

To the extent any indemnification
by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution with respect
to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; provided, however,
that: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation;
and (ii) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such
seller from the sale of such Registrable Securities.

 

8.             REPORTS
AND DISCLOSURE UNDER THE SECURITIES ACTS.

 

With a view to making available
to the Investor the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that
may at any time permit the Investor to sell securities of the Company to the public without registration (“Rule 144”),
the Company agrees, at the Company’s sole expense, to:

 

(a)               
make and keep public information available, as those terms are understood and defined in Rule 144;

 

(b)               
file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the
Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required
for the applicable provisions of Rule 144;

 

(c)               
furnish to the Investor so long as the Investor owns Registrable Securities, promptly upon reasonable request, (i) a written statement
by the Company that it has complied with the reporting and or disclosure provisions of Rule 144, the Securities Act and the Exchange
Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company,
and (iii) such other information as may be reasonably requested to permit the Investor to sell such securities pursuant to Rule 144 without
registration; and

 

     9

     

    

 

(d)               
take such additional action as is reasonably requested by the Investor to enable the Investor to sell the Registrable Securities
pursuant to Rule 144, including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions
to the Company’s Transfer Agent as may be reasonably requested from time to time by the Investor and otherwise fully cooperate
with the Investor and the Investor’s broker to effect such sale of securities pursuant to Rule 144; provided, however,
that the Investor and its broker shall cooperate with the Company and its counsel and provide the necessary certificates, instructions
and other documents reasonably requested by the Company or its counsel in order to enable the Investor to sell the Registrable Securities
pursuant to Rule 144.

 

The Company agrees that damages
may be an inadequate remedy for any breach of the terms and provisions of this Section 8 and that the Investor shall, whether or not
it is pursuing any remedies at law, be entitled to seek equitable relief in the form of a preliminary or permanent injunction, without
having to post any bond or other security, upon any breach or threatened breach of any such terms or provisions.

 

9.             ASSIGNMENT
OF REGISTRATION RIGHTS.

 

The Company shall not assign
this Agreement or any rights or obligations hereunder without the prior written consent of the Investor; provided, however,
that any transaction, whether by merger, reorganization, restructuring, consolidation, financing or otherwise, whereby the Company remains
the surviving entity immediately after such transaction shall not be deemed an assignment. The Investor may not assign its rights under
this Agreement without the written consent of the Company, other than to an affiliate of the Investor controlled by Jonathan Cope or
Josh Scheinfeld, in which case the assignee must agree in writing to be bound by the terms and conditions of this Agreement.

 

10.           AMENDMENT
OF REGISTRATION RIGHTS.

 

No provision of this Agreement
may be amended or waived by the parties from and after the date that is one (1) Business Day immediately preceding the initial filing
of the Registration Statement with the SEC. Subject to the immediately preceding sentence, no provision of this Agreement may be (i)
amended other than by a written instrument signed by the parties hereto or (ii) waived other than in a written instrument signed by the
party against whom enforcement of such waiver is sought. Failure of any party to exercise any right or remedy under this Agreement or
otherwise, or delay by a party in exercising such right or remedy, shall not operate as a waiver thereof.

 

11.           MISCELLANEOUS.

 

(a)               
A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or elections from two or more Persons with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions, notice or election received from the registered owner of
such Registrable Securities.

 

     10

     

    

 

(b)               
Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must
be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by
facsimile or email (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending
party); or (iii) one (1) Business Day after deposit with a nationally recognized overnight delivery service, in each case properly addressed
to the party to receive the same. The addresses for such communications shall be:

The corporate laws of the State of Delaware shall govern all issues concerning the relative rights of the Company and its stockholders.
All other questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the
internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the
State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State
of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the State
of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated

Re: [__________]

  

Ladies and Gentlemen:

 

Reference is hereby made
to that certain Purchase Agreement, dated as of August [●], 2022 (the “Purchase Agreement”), entered into
by and between Nuburu, Inc. (f/k/a Tailwind Acquisition Corp.), a Delaware corporation (the “Company”), and Lincoln
Park Capital Fund, LLC (the “Buyer”) pursuant to which, among other things, the Company has agreed following the Closing
(as defined in the Purchase Agreement) to issue to the Buyer shares of the Company’s Common Stock, par value $0.0001 per share
(the “Common Stock”), in an amount up to one hundred million dollars ($100,000,000), in accordance with the terms
of the Purchase Agreement. In connection with the transactions contemplated by the Purchase Agreement, the Company has registered with
the U.S. Securities and Exchange Commission (the “SEC”) [__________] shares of Common Stock that may be issued and
sold by the Company to the Buyer from time to time (the “Purchase Shares”) and [___________] shares of Common Stock
as Commitment Shares (the “Commitment Shares”).

 

We are counsel to the Company,
and this letter is being delivered pursuant to that certain Registration Rights Agreement, dated as of August [●], 2022, entered
into by and between the Company and the Buyer (the “Registration Rights Agreement”) pursuant to which the Company
agreed, among other things, to register the Purchase Shares and the Commitment Shares under the Securities Act of 1933, as amended (the
 “Securities Act”).

 

In connection with the Company’s
obligations under the Purchase Agreement and the Registration Rights Agreement, on [_____________], 20[__], the Company filed a Registration
Statement (File No. 333-[_________]) (the “Registration Statement”) with the SEC relating to the resale of the
Purchase Shares and the Commitment Shares by the Buyer.

 

In connection with the foregoing,
we advise you that a member of the SEC’s staff has advised us by telephone that the SEC has entered an order declaring the Registration
Statement effective under the Securities Act at __:__ am/pm on _______ __, 2022, and we have no knowledge, based solely on our review
of the SEC’s “Stop Orders” web page (http://sec.gov/litigation/stoporders.shtml), that any stop order suspending
the Registration Statement’s effectiveness has been issued or that any proceedings for that purpose are pending before, or threatened
by, the SEC.

 

	 	Very truly yours,
	 	 
	 	[Company Counsel]
	 	 

	 	By:	 
	 
	cc:          Lincoln Park Capital
    Fund, LLC
