| Confidential KEY RISK FACTORS Unless the context requires otherwise, references to “NUBURU,” “we,” “us” or “our” in this section are to the business and operations of NUBURU prior to the Transaction and to combined company and its subsidiaries following the Transaction. The risks presented below are certain of the general risks related to our business, and such list is not exhaustive. The list below is qualified in its entirety by disclosures contained in future documents to be filed or furnished by NUBURU and TWND, with the SEC, including the documents filed or furnished in connection with the proposed Transactions between NUBURU and TWND. The risks presented in such filings will be consistent with those that would be required for a public company in its SEC filings, including with respect to the business and securities of NUBURU and TWND and the proposed transactions between NUBURU and TWND, and may differ significantly from and be more extensive than those presented below. The risks described below are not the only ones NUBURU or TWND faces. Additional risks that are not currently known or that are currently believed to be immaterial may also impair our business, financial condition or results of operations. You should review the investor presentation and perform your own due diligence prior to making an investment in TWND. Risks Relating to Our Business and Operations .. We are an early-stage company with a history of losses. We have not been profitable historically and may not be able to achieve profitability in the future. .. Our limited operating history and the novelty of our blue laser systems make evaluating our business, the risks and challenges we may face and our future prospects difficult. .. The engineering of our laser systems is still in the prototype stage, and there is no guarantee that we will be successful in implementing production of our laser systems on a commercial scale. .. If our laser systems contain design or manufacturing defects, our business and financial results could be harmed. .. Insufficient warranty reserves to cover future warranty claims could adversely affect our business, prospects, financial condition and operating results. .. The failure of our suppliers to deliver necessary raw materials and components that meet the specifications for our laser systems in a timely manner could cause installation delays, cancellations and damage to our reputation. .. We depend on sole source or limited source suppliers, as well as on our own production capabilities, for some of the key components and materials, including laser diodes and optical filters, which makes us susceptible to supply shortages and other supply chain disruptions and to price fluctuations that could adversely affect our business, particularly our ability to meet our customers’ delivery requirements. .. We are highly dependent upon the ability to ship products to customers and to receive shipments of supplies from suppliers. .. If we fail to accurately forecast component and material requirements for our products, we could incur additional costs and significant delays in shipments, which could result in a loss of customers. .. There is no assurance that non-binding letters of intent and other indications of interest from customers will be converted into binding orders, sales, bookings or committed offtake contracts. As a result, our operating results may be materially lower than our expected results of operations. .. Our systems involve a lengthy sales and installation cycle, and if we fail to close sales on a regular and timely basis it could harm our business. The long sales cycles for our products may cause us to incur significant expenses without offsetting revenues. .. Because of the long sales cycles, our operating results and financial condition may fluctuate significantly from quarter to quarter. .. If we fail to meet our customers’ price expectations, demand for our products could be negatively impacted and our business and results of operations could suffer. .. We expect to contract with a number of large companies that have considerable bargaining power, which may require us to agree to terms and conditions that could have an adverse effect on our business or ability to recognize revenues. .. Declines in the prices of our products and services, or in our volume of sales, together with our relatively inflexible cost structure, may adversely affect our financial results. .. If we are not able to continue to reduce our cost structure in the future, our ability to become profitable may be impaired. .. In the event of future growth, our information technology systems and our internal control over financial reporting and procedures may not be adequate to support our operations. .. We are highly dependent on current key executives and if we are unable to attract and retain key employees and hire qualified management, technical, engineering, and sales personnel, our ability to compete and successfully grow our business could suffer. .. Labor disputes could disrupt our ability to serve our customers or lead to higher labor costs. .. Our expectations and targets regarding the times when we will launch our products depend in large part upon assumptions, estimates, measurements, testing, analyses and data developed and performed by us, which if incorrect or flawed, could have a material adverse effect on our actual operating results and performance. .. Certain estimates of market opportunity and forecasts of market growth may prove to be inaccurate. .. Incorrect estimates or assumptions by management in connection with the preparation of our consolidated financial statements could adversely affect our reported assets, liabilities, income, revenue or expenses. 32

GRAPHIC

| Confidential Risks Relating to Our Business and Operations (continued) .. Operational costs can be difficult to predict and may include costs from requirements related to the decommissioning of our systems. .. We expect to incur significant research and development expenses and devote substantial resources to commercializing new products, which could increase our losses and negatively impact our ability to achieve or maintain profitability. .. Our ability to use net operating loss (“NOL”) carryforwards and other tax attributes may be limited in connection with the proposed Transaction and other ownership changes. .. Our insurance coverage may not adequately protect us from harm or losses we may suffer. .. The implementation of our business plan and strategy may require additional capital and this capital might not be available on acceptable terms, if at all. .. There is no assurance that we will be able to execute on our business model. .. Expanding operations internationally will subject us to a variety of risks and uncertainties that could adversely affect our business and operating results. Risk Relating to Our Industry .. Our future growth is dependent upon the competition, pace and depth of blue laser adoption, as well as on the growth of certain end markets. If such markets do not develop as we expect, or if they develop more slowly than we expect, our business, prospects, financial condition and operating results could be adversely affected. .. If the cost of competitive technologies continues to decline, our blue laser technology may not be considered as cost-effective when compared to such competing technologies. .. Our systems are based on novel technologies to produce blue wavelength lasers and potential customers may be hesitant to make a significant investment in our technology or switch from the technology they are currently using. .. The average selling prices of our products could decrease over the life of the product, which may negatively affect our revenue and margins. .. We operate in a highly competitive industry and there is increasing competition. Many of our competitors and future competitors may have significantly more financial and other resources than we do and if we do not compete effectively, our competitive positioning and our operating results will be harmed. .. Our market is characterized by rapid technological changes and evolving standards demanding a significant investment in research and development, and, if we fail to address changing market conditions, our business and operating results will be harmed. .. Global economic conditions and macro events may adversely affect us. Risk Relating to Litigation and Regulation .. Changes in laws or regulations, or a failure to comply with any laws and regulations, may adversely affect our business, including our ability to complete the business combination, and results of operations. .. Litigation, regulatory actions and compliance issues could subject us to significant fines, penalties, judgments, remediation costs, negative publicity and requirements resulting in increased expenses. .. We may be subject to securities litigation, which is expensive and could divert management attention. .. Our manufacturing facilities are subject to various compliance requirements, including Occupational Safety and Health Administration (“OSHA”), and compliance costs could increase as we plan to scale our operations. .. Laws, regulations and rules relating to privacy, information security, and data protection could increase our costs and adversely affect our business opportunities. In addition, the ongoing costs of complying with such laws, regulations and rules could be significant. .. Our business may depend on the continued availability of rebates, tax credits and accelerated depreciation schedules, and other financial incentives. The reduction, modification, or elimination of government economic incentives, particularly in the defense and research sectors, and tax policies could cause our revenue to decline and harm our financial results. .. Unanticipated changes in tax laws may affect future financial results. .. We must comply with and could be impacted by various export controls and trade and economic sanctions laws and regulations that could negatively affect our business and may change due to diplomatic and political considerations outside of our control. .. We could be liable for environmental damages resulting from our operations, which could impact our reputation, our business, and our operating results. 33

| Confidential Risk Relating to Intellectual Property .. We may be unable to protect, defend, maintain or enforce our intellectual property rights for the intellectual property on which our business depends, including against existing or future competitors. Failure to protect defend, maintain and enforce that intellectual property could result in our competitors offering similar products, potentially adversely affecting our growth and success. .. We may be subject to third-party claims of infringement, misappropriation or other violations of intellectual property rights, or other claims challenging our agreements related to intellectual property, which may be time-consuming and costly to defend, and could result in substantial liability. .. Our patents and, patent applications if issued, may not provide adequate protection to create a barrier to entry. The provisional and non-provisional patent applications that we own may not issue as patents or provide adequate protection to create a barrier to entry, which may hinder our ability to prevent competitors from selling products similar to ours. .. Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our intellectual property rights. Other Risks .. Cyber-attacks and other disruptions, security breaches and incidents could have an adverse effect on our business, harm our reputation and expose us to liability. .. Natural disasters, unusual weather conditions, epidemic outbreaks, terrorist acts and political events could disrupt our business. Interruption or failure of our infrastructure could hurt our ability to effectively perform our daily operations and provide and produce our products and services, which could damage our reputation and harm our operating results. .. Our financial condition and results of operations as well as those of potential customers could be adversely affected by epidemics, pandemics and other outbreaks such as the COVID-19 pandemic, which has caused a material adverse effect on the level of economic activity around the world. .. Our financial condition and results of operations as well as those of potential customers could be adversely affected by the Russian invasion of Ukraine, which has caused a material adverse effect on the level of economic activity around the world. .. We may engage in a wide array of potential strategic transactions, which could require significant management attention, disrupt our business, dilute stockholder value and adversely affect our operating results and financial condition. .. Negative publicity could result in a decline in our growth and have a material adverse effect on our business, our brand and our results of operations. Risk Relating to Being a Public Company .. Our quarterly results and key metrics are likely to fluctuate significantly and may not fully reflect the underlying performance of our business. .. We will incur increased costs as a result of operating as a public company, and our management will be required to devote substantial time to compliance with our public company responsibilities and corporate governance practices. .. We are an “emerging growth company,” and our election to comply with the reduced disclosure requirements as a public company may make our common stock less attractive to investors. .. We may face litigation and other risks as a result of the material weakness in our internal control over financial reporting. .. Changes in accounting principles may cause previously unanticipated fluctuations in our financial results, and the implementation of such changes may impact our ability to meet our financial reporting obligations. .. Our management has limited experience in operating a public company. Risks Relating to the Business Combination .. NUBURU and TWND stockholders will have a reduced ownership and voting interest after the Business Combination and will exercise less influence over management. .. The market price of shares of New NUBURU Common Stock after the Business Combination may be affected by factors different from those currently affecting the prices of shares of Class A Common Stock. .. TWND has not obtained an opinion from an independent investment banking firm, and consequently, there is no assurance from an independent source that the merger consideration is fair to its stockholders from a financial point of view. .. The consummation of the Business Combination is subject to a number of conditions and, if those conditions are not satisfied or waived, the Business Combination Agreement may be terminated in accordance with its terms and the Business Combination may not be completed. .. Termination of the Business Combination Agreement could negatively impact TWND. .. TWND directors and officers may have interests in the Business Combination different from the interests of TWND stockholders. .. The Business Combination Agreement contains provisions that may discourage TWND from seeking an alternative business combination. 34

GRAPHIC

| Confidential Risks Relating to the Business Combination (continued) .. The Business Combination will result in changes to the board of directors of New NUBURU that may affect the strategy of New NUBURU. .. TWND and NUBURU will incur transaction costs in connection with the Business Combination. .. Stockholders will have their rights as stockholders governed by the Post-Closing New NUBURU’s Governing Documents. .. The Sponsor has agreed to vote in favor of the proposals at the TWND Special Meeting, regardless of how public stockholders vote. .. Because of TWND’s limited resources and the significant competition for business combination opportunities, it may be more difficult for it to complete the initial business combination. .. TWND may not be able to consummate the Business Combination or an initial business combination within the required time period, in which case it would cease all operations except for the purpose of winding up and it would redeem the Class A Common Stock and liquidate, in which case the holders of Class A Common Stock may only receive approximately $10.00 per share, or less than such amount in certain circumstances, and the public warrants will expire worthless. .. TWND’s Sponsor, directors, officers, advisors and their affiliates may elect to purchase shares or Public Warrants from holders of Class A Common Stock, which may influence the vote on the Business Combination Proposal and reduce the public float of the Class A Common Stock. .. Neither TWND nor its stockholders will have the protection of any indemnification, escrow, price adjustment or other provisions that allow for a post-closing adjustment to be made to the total merger consideration in the event that any of the representations and warranties made by NUBURU in the Business Combination Agreement ultimately proves to be inaccurate or incorrect. .. Either TWND or NUBURU may waive one or more of the conditions to the Business Combination or certain of the other transactions contemplated by the Business Combination Agreement. .. TWND does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for TWND to consummate an initial business combination with which a substantial majority of TWND’s stockholders do not agree. .. If third parties bring claims against TWND, the proceeds held in the Trust Account could be reduced and the per-share redemption amount received by stockholders may be less than $10.00 per share. .. TWND and its directors are, or may in the future be, subject to claims, suits and other legal proceedings, including challenging the Business Combination, that may result in adverse outcomes, including preventing the Business Combination from becoming effective or from becoming effective within the expected time frame. .. TWND’s directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to the holders of Class A Common Stock. .. TWND may not have sufficient funds to satisfy indemnification claims of its directors and executive officers. .. If, after TWND distributes the proceeds in the Trust Account to the holders of Class A Common Stock, it files a bankruptcy petition or an involuntary bankruptcy petition is filed against TWND that is not dismissed, a bankruptcy court may seek to recover such proceeds, and TWND and its board may be exposed to claims of punitive damages. .. If, before distributing the proceeds in the Trust Account to the holders of Class A Common Stock, TWND files a bankruptcy petition or an involuntary bankruptcy petition is filed against TWND that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of TWND’s stockholders and the per-share amount that would otherwise be received by TWND’s stockholders in connection with TWND’s liquidation may be reduced. .. TWND stockholders may be held liable for claims by third parties against TWND to the extent of distributions received by them upon redemption of their shares. .. TWND may amend the terms of its warrants in a manner that may be adverse to holders of Public Warrants with the approval by the holders of at least 50% of the then outstanding Public Warrants. As a result, the exercise price of the warrants could be increased, the exercise period could be shortened and the number of shares of Class A Common Stock purchasable upon exercise of a Public Warrant could be decreased, all without your approval. .. TWND may redeem your unexpired warrants prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless. .. Subsequent to the consummation of the Business Combination and the other transactions contemplated by the Business Combination Agreement, New NUBURU may be required to take write-downs or write-offs, or the combined company may be subject to restructuring, impairment or other charges that could have a significant negative effect on the combined company’s financial condition, results of operations and the price of New NUBURU Common Stock, which could cause you to lose some or all of your investment. .. The future exercise of registration rights may adversely affect the market price of New NUBURU Common Stock. .. Warrants will become exercisable for New NUBURU Common Stock and the New NUBURU Series A Preferred Stock will be convertible into New NUBURU Common Stock, each of which would increase the number of shares eligible for future resale in the public market and result in dilution to New NUBURU stockholders. .. There is no guarantee that our warrants will be in the money at the time they become exercisable, and they may expire worthless. .. The Pre-Closing TWND Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in TWND’s name, actions against TWND’s directors, officers, other employees or stockholders for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel, which may have the effect of discouraging lawsuits against TWND’s directors, officers, other employees or stockholders. 35

GRAPHIC

| Confidential Risks Relating to the Business Combination (continued) .. Since the Sponsor and TWND’s officers and directors who are members of the Sponsor have interests that are different, or in addition to (and which may conflict with), the interests of the public stockholders, a conflict of interest may have existed in determining whether the Business Combination with NUBURU is appropriate as a business combination. Such interests include that Sponsor will lose its entire investment in us if our business combination is not completed. .. The process of taking a company public by means of a business combination with a special purpose acquisition company (“SPAC”) is different from taking a company public through an underwritten offering and may create risks for our unaffiliated investors. .. We will have broad discretion in the use of the net proceeds to us from the Business Combination, you may not agree with how we use the proceeds and the proceeds may not be invested successfully. .. Because the market price of shares of New NUBURU Common Stock will fluctuate, NUBURU stockholders cannot be sure of the value of the merger consideration they will receive. .. NUBURU will be subject to business uncertainties and contractual restrictions while the merger is pending. .. Incorrect estimates or assumptions made in connection with the preparation of the financial statements contained in this proxy statement/prospectus could adversely affect New NUBURU’s reported assets, liabilities, income, revenue or expenses. .. TWND currently intends to only complete one business combination with the proceeds of the TWND IPO and the sale of the private placement warrants, which will cause TWND to be solely dependent on NUBURU’s business. This lack of diversification may negatively impact TWND’s operations and profitability. .. We will require substantial additional capital to finance our operations. If we are unable to raise such capital when needed, or on acceptable terms, that could have a material adverse effect on the continued growth and development of New NUBURU. Risks Related to Ownership of New NUBURU Common Stock and New NUBURU Series A Preferred Stock Following the Business Combination .. New NUBURU Common Stock will be subordinated to shares of New NUBURU Series A Preferred Stock issued in the Preferred Stock Issuance. .. Shares of New NUBURU Series A Preferred Stock may be subordinate to any senior preferred stock New NUBURU may issue and to any future indebtedness. .. At the two-year anniversary of the Preferred Stock Issuance, New NUBURU is obligated to redeem shares of New NUBURU Series A Preferred Stock for cash. There can be no guarantee that New NUBURU will have funds available to make this redemption. .. The NYSE may delist New NUBURU’s securities from trading on its exchange, which could limit investors’ ability to make transactions in its securities and subject New NUBURU to additional trading restrictions. .. If the NUBURU Common Stock is delisted from trading, the ability of holders of New NUBURU Series A Preferred Stock to transfer or sell their shares of the New NUBURU Series A Preferred Stock may be limited and the market value of the New NUBURU Series A Preferred Stock will likely be materially adversely affected. .. New NUBURU’s stock price may change significantly following the Business Combination and you could lose all or part of your investment as a result. .. There is no public market for the Series A Preferred Stock being offered in this offering. .. Because there are no current plans to pay cash dividends on New NUBURU Common Stock or New NUBURU Series A Preferred Stock for the foreseeable future, you may not receive any return on investment unless you sell your shares for a price greater than that which you originally paid. .. If securities analysts do not publish research or reports about New NUBURU’s business or if they downgrade New NUBURU’s stock or New NUBURU’s industry, New NUBURU’s stock price and trading volume could decline. .. Future sales, or the perception of future sales, by New NUBURU or its stockholders in the public market following the Business Combination could cause the market price for New NUBURU Common Stock to decline. .. Anti-takeover provisions in New NUBURU’s organizational documents could delay or prevent a change of control. .. If the Merger does not qualify as a reorganization under Section 368(a) of the Code, U.S. Holders of NUBURU Common Stock may be required to pay substantial U.S. federal income taxes. .. As a holder of New NUBURU Series A Preferred Stock, you will have extremely limited voting rights. .. The Public Stockholders will experience immediate dilution. 36

GRAPHIC

| Confidential Risks Relating to Redemption .. There is no guarantee that a TWND public stockholder’s decision whether to redeem their shares for a pro rata portion of the Trust Account will put such stockholder in a better future economic position. .. If TWND public stockholders fail to comply with the redemption requirements specified in this proxy statement/prospectus, they will not be entitled to redeem their shares of Class A Common Stock for a pro rata portion of the funds held in the Trust Account. .. If you or a “group” of stockholders of which you are a part are deemed to hold an aggregate of more than 15% of the shares of Class A Common Stock, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15% of the Class A Common Stock. .. There is uncertainty regarding the federal income tax consequences of the redemption to the holders of Class A Common Stock. .. If a stockholder fails to receive notice of TWND’s offer to redeem TWND’s public shares in connection with the Business Combination, or fails to comply with the procedures for tendering its shares, such shares may not be redeemed. .. Significant redemptions among TWND’s public shareholders may require New NUBURU to raise future financing after the closing of the Business Combination. .. A new 1% U.S. federal excise tax could be imposed on us in connection with redemptions. 37
