| 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 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. 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. 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. 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 and/or lead to higher labor costs. 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
| 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. 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 other financial incentives. The reduction, modification, or elimination of government economic incentives, particularly in the defense and research sectors, 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 security breaches 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 management has limited experience in operating a public company. Following the consummation of the Transaction, we expect to incur significant increased expenses and administrative burdens as a public company, which could negatively impact our business, financial condition and results of operations. As a private company, we have not endeavored to establish and maintain public company-quality internal control over financial reporting. If we fail to establish and maintain proper and effective internal control over financial reporting as a public company, our ability to produce accurate and timely financial statements could be impaired, investors may lose confidence in our financial reporting and the trading price of our common stock may decline. Risks Relating to the Business Combination We will have broad discretion in the use of the net proceeds to us from this offering, 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 TWND’s common stock will fluctuate, NUBURU stockholders cannot be sure of the value of the merger consideration they will receive. TWND and NUBURU stockholders will have a reduced ownership and voting interest in the combined company after the merger. The market price of shares of our common stock after the merger may be affected by factors different from those currently affecting the prices of shares of TWND common stock. If the merger’s benefits do not meet the expectations of financial analysts, the market price of our common stock may decline. The consummation of the merger is subject to a number of conditions and if those conditions are not satisfied or waived, the merger agreement may be terminated in accordance with its terms and the merger may not be completed. Termination of the merger agreement could negatively impact TWND and NUBURU. 34
| Confidential Risks Relating to the Business Combination (continued) TWND and its directors are, or may in the future be, subject to claims, suits and other legal proceedings, including challenging the merger, that may result in adverse outcomes, including preventing the merger from becoming effective or from becoming effective within the expected time frame. NUBURU will be subject to business uncertainties and contractual restrictions while the merger is pending. NUBURU directors and officers may have interests in the merger different from the interests of NUBURU’s stockholders. TWND directors and officers may have interests in the merger different from the interests of TWND’s stockholders. The merger will result in changes to the board of directors of the post-combination entity that may affect the strategy of the post-combination entity. The merger agreement contains provisions that may discourage other companies from trying to acquire NUBURU for greater merger consideration. The merger agreement contains provisions that may discourage TWND from seeking an alternative business combination. Incorrect estimates or assumptions by management in connection with the preparation of our financial statements could adversely affect our reported assets, liabilities, income, revenue or expenses. TWND and NUBURU will incur transaction costs in connection with the merger. Subsequent to the closing of the merger, the post-combination entity may be exposed to unknown or contingent liabilities and may be required to subsequently take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, results of operations and the price of our securities, which could cause you to lose some or all of your investment. TWND’s and NUBURU’s equityholders will have their rights as stockholders governed by the organizational documents of the post-combination entity. 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. 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 reduced. Risks Relating to Redemption Significant redemptions among TWND’s public stockholders may require the post-combination entity to raise future financing after the closing of the merger. There is no guarantee that TWND’s 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, they will not be entitled to redeem their public shares for a pro rata portion of the funds held in the Trust Account. TWND does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for TWND to complete the merger with which a substantial majority of TWND’s stockholders do not agree. Risks Relating to Ownership of Our Common Stock and Warrants If the post-combination entity does not declare any dividends in the future, you will have to rely on price appreciation of our commons stock in order to achieve a return on your investment. If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about business of the post-combination entity, or if they adversely change their recommendations regarding the common stock of the post-combination entity or if results of operations of the post-combination entity do not meet their expectations, the market price of the common stock and trading volume of the post-combination entity could decline. The price of common stock and warrants of the post-combination entity may be volatile and subject to wide fluctuations. Future resales, or the perception of future resales, of our common stock after the consummation of the Transaction, including those issued upon exercise of warrants, may cause the market price of our securities to drop significantly, even if our business is doing well. We expect to be an “emerging growth company,” and the reduced disclosure requirements applicable to emerging growth companies could make our common stock less attractive to investors. There is no guarantee that our warrants will be in the money at the time they become exercisable, and they may expire worthless. 35
