Forward-Looking Statements and Cautionary Language. Certain statements included in this presentation that are not historical facts are forward-looking statements, including for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "could," "plan," "predict," "potential," "projected," "seem," "seek," "future," "outlook," and similar words and expressions that predict or indicate future circumstances, events or trends or that otherwise are not statements of historical matters. These forward- looking statements include, but are not limited to, statements regarding MariaDB's business strategy, estimated total addressable market, commercial and operating plans, product development plans, customers, and projected financial condition and performance, and actions by investors and shareholders in MariaDB and Angel Pond and the outcome of the Proposed Transactions. These statements are based on various estimates and assumptions, whether or not identified in this presentation, and on the current expectations of the respective management of MariaDB and Angel Pond and others, and are not predictions of actual actions, events or performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as, a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from estimates and assumptions made, sometimes materially. Many actual events and circumstances are beyond the control of MariaDB and Angel Pond. These forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, that MariaDB may be unable to successfully commercialize its products or expand its markets; the effects of competition on MariaDB's business; the uncertainty of the projected financial information with respect to MariaDB; disruptions and other impacts to MariaDB's business as a result of the COVID-19 pandemic and other global health or economic crises; changes in customer and potential customer demand; the parties may be unable to successfully or timely consummate one or more of the Proposed Transactions, including the risk that any regulatory (including foreign, SEC or securities exchange) approvals or necessary actions are not obtained, delayed r are subject to un anticipated conditions that could adversely affect the combined company xpec benefits any the Proposed Transactions, or t the approval of shareholders of MariaDB or Angel Pond is not obtained; failure to realize the anticipated benefits of the equity bridge financing (including failure to raise the estimated $100 million or any lower amount) or any of the Proposed Transactions (including failure to raise $50 million or any lower amount in the PIPE financing); the amount of redemption or similar requests made by MariaDB's or Angel Pond's shareholders (including the potential that Angel Pond's shareholders could redeem significantly more than 0% of their shares in connection with the Proposed Business Combination, which would cause, among other things, potentially significantly less cash from its trust to be provided to the combined company); and those factors discussed elsewhere in this presentation and in Angel Pond's final prospectus filed with the SEC on May 19, 2021, including under the heading "Risk Factors," and other documents Angel Pond has filed, or may file, with the SEC. If any of these risks materialize or the estimates or assumptions prove incorrect, actual results could differ materially from the events, results and condition implied by these forward-looking statements. Proprietary & Confidential MariaDB 2#3DISCLAIMERS (cont'd) There may be additional risks that neither MariaDB nor Angel Pond presently know, or that MariaDB or Angel Pond currently believe are immaterial, that could also cause actual events, results or condition to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect MariaDB's and Angel Pond's expectations, plans, or forecasts of future events and views as of the date of this presentation. MariaDB and Angel Pond anticipate that subsequent events and developments will cause MariaDB's and Angel Pond's assessments to change. However, while MariaDB and Angel Pond may elect to update these forward-looking statements at some point in the future, MariaDB and Angel Pond specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing MariaDB's or Angel Pond's assessments of any date subsequent to the date of this presentation. Accordingly, undue reliance should not be placed upon any forward-looking statements. Additional Information and Where to Find It.

MariaDB, Angel Pond and their respective directors and executive officers may be deemed to be participants in the solicitation of proxies from Angel Pond's shareholders in connection with one or more of the Proposed Transactions, including the Proposed Business Combination. Information about Angel Pond's directors and executive officers and their ownership of Angel Pond's securities is set forth in Angel Pond's final prospectus filed with the SEC on May 19, 2021.

This presentation is not a proxy statement or solicitation of a proxy, consent or authorization with respect to any securities or in respect of any of the Proposed Transactions and shall not constitute an offer to sell or a solicitation of an offer to buy the securities of MariaDB or Angel Pond, or the combined company, nor shall there be any sale of any such securities in any state or jurisdiction, U.S. or foreign, in which such offer, solicitation or sale would be unlawful prior to applicable registration or qualification or exemption under the securities laws of such state or jurisdiction. Financial Information. The financial information contained in this presentation has been taken from or prepared based on the historical financial statements and certain other financial information of MariaDB for the periods presented. MariaDB's historical and other financial information is prepared in accordance with International Financial Reporting Standards ("IFRS"). None of such information has been audited in accordance with IFRS or generally accepted accounting principles in the U.S. ("U.S. GAAP"), or Public Company Accounting Oversight Board ("PCAOB") standards. We cannot assure you that had the financial statements been compliant with Regulation S-X under the Securities Act of 1933, as amended, or audited in accordance with IFRS, U.S. GAAP or PCAOB standards, there would not be differences and such differences would not be material. An audit of certain of MariaDB's financial statements in accordance with U.S. GAAP and applicable PCAOB standards is in process and will be included in the combined registration statement and proxy statement to be filed with the SEC, which you should review. Accordingly, there will be differences, potentially material, between the presentation of the financial information included in this presentation and in the combined registration statement and proxy statement for the Proposed Business Combination. Use of Projections. This presentation contains certain projected financial information regarding MariaDB and the combined company, including certain revenue information, among others. Such projected financial information is forward- looking and is for illustrative purposes only, and will likely differ, potentially materially, from projected financial information included in a combined registration statement and proxy statement relating to the Proposed Business Combination. It should not be relied upon as being indicative of future results or condition. The estimates and assumptions underlying such projected financial information are inherently uncertain and are subject to many significant business, economic, competitive and other risks and uncertainties. Refer to "Forward-Looking Statements" above. Actual results and condition may differ materially from the results presented in such projected financial information, and the inclusion of such. information in this presentation should not be regarded as a representation by any person that the results reflected in such projections will be achieved. Neither MariaDB's nor Angel Pond's auditors have audited, reviewed, compiled or performed any procedures with respect to the projected financial information for the purpose of their inclusion in the presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of the presentation.

ARR does not have a standardized meaning and is therefore unlikely to be comparable to similarly titled measures presented by other companies. ARR should be viewed independently of revenue and is not intended to be combined with or to replace that item Average rate of growth over a period of time Churn refers to a reduction of ARR that was present on day 1 of a fiscal period and DECREASES during the period Logos refers to clients and new logos means new clients The company's open source software is code that is designed to be publicly accessible-anyone can see, modify, and distribute the code as they see fit ● MariaDB 44#45RISK FACTORS SUMMARY Investing in any of the Proposed Transactions relating to this presentation involves a high degree of risk. Below is a summary of certain factors that make an investment in any Proposed Transaction speculative and risky. Additional discussion of risks and uncertainties summarized in this risk factors summary, and other risks and uncertainties relevant to a transaction, should be reviewed as described in the "Disclaimers, Forward-Looking Statements and Cautionary Language" section of this presentation, as well as proxy statement/prospectus filed in connection with the Proposed Business Combination. • MariaDB's limited operating history makes it difficult to predict our future results of operations. • MariaDB has a history of losses and we may not achieve or maintain profitability in the future. • MariaDB's financial projections rely in part on assumptions about customer demand based on ongoing relationships and indications from current and prospective customers, among other factors. Our failure to secure that projected business could have an adverse impact on our financial results and condition and could cause our actual results to be materially different from those projected. Our projections rely on numerous other assumptions and factors that may be inaccurate or become inaccurate and that could cause our financial results and condition to materially differ from those projected. • MariaDB will require additional capital to support our future growth, and such capital may not be available on terms that are acceptable or at all. • The market for our products and services is evolving and its potential growth may be constrained by prospective customers' significant existing investments in other third-party relationships (including in the database solutions of their current providers). • Our success is highly dependent on our ability to penetrate the existing market for database products, as well as the growth and expansion of the market for database products notably cloud-based products. • If we fail to continue to grow and to effectively manage our growth, we may be unable to successfully execute our business plan, increase revenue, improve our financial results, maintain high levels of service, or adequately address competitive challenges. • The database software market is highly competitive, and MariaDB faces significant competition from larger, better-capitalized companies, including traditional relational database providers such as IBM, Microsoft and Oracle, cloud providers with database functionalities such as Amazon Web Services, Microsoft Azure and Google Cloud Platform, and non-relational database software providers. MariaDB could lose market share to these providers of products and services that can be substituted for our products and services. • If we are not able to maintain and enhance the MariaDB brand, especially among developers and outside of the open-source community, our business and results of operations may be adversely affected. • Technological changes, the introduction of new or enhanced products and services by our competitors, and pricing pressures may negatively impact demand for our products and services, as well as our financial performance, including our margin. • The loss of one or more of our significant customers or a significant reduction of business with such customers could materially affect our financial results and condition, as well as our business generally. • If we fail to cost-effectively acquire new customers and retain and expand our relationships with existing customers through renewals and upgrades, we may fail to increase our revenues enough to achieve profitability. • Our sales cycles may become longer and unpredictable, and our sales efforts require considerable time and expense. • Because we offer the open-source MariaDB Community Server as a free-to-download product, our ability to monetize and protect intellectual property rights for our products and services may be negatively impacted. • Because our ability to attract new and retain existing customers depends on our success at enhancing and improving our products and services in response to changing customer needs, technologies and regulations, a failure to continue to innovate would adversely affect our growth and profitability. • We have invested significantly in our MariaDB products and services, including our cloud offering, SkySQL, and our MariaDB Enterprise product offerings, and if any of these were to fail to achieve broader market adoption our business, results of operations and financial condition could be harmed. • Incorrect or improper implementation or use of our software could result in customer dissatisfaction and harm our business, results of operations, financial condition and growth prospects. • We rely upon third-party cloud providers to host our cloud offering; any disruption of or interference with our use of third-party cloud providers would adversely affect our business, results of operations and financial condition. • Our expected scale-up will result in a significant increase in the costs of cloud capacity, which could adversely affect our growth and profitability. Proprietary & Confidential MariaDB 45#46RISK FACTORS SUMMARY (cont'd) • Without significant investments in our sales and marketing organizations and improvements in sales and marketing programs, we may be unable to add new customers or increase sales to existing customers at a level needed to achieve our growth expectations. • We may require significant additional capital investment into research and development, including in the area of intellectual property and other proprietary technology, the failure of which to secure could adversely impact our business. • Our success depends on our ability to expand and enhance our workforce to support future growth, and our inability to attract and retain employees in key areas such as software development, sales and marketing, and customer support would adversely affect our growth prospects and results of operations. • Real or perceived errors, bugs or other problems with our products and services (including data loss or failure to meet our contractual obligations) may adversely affect our relationship with existing customers and deter prospective customers, require us to expend significant resources and expenses to address the problems, and impede market acceptance of our products and services. • If we fail to offer high quality support, for example with our remote database administration services, our business and reputation could suffer. • Our business could suffer disruptions, outages, defects, and other performance and quality problems due to issues with public platforms, the public cloud and internet infrastructure on which our products and services rely, which could negatively affect our business. • Because database products and services such as those we offer are often used to collect and store personal information, domestic and international privacy concerns, including complex and onerous regulatory requirements (such as HIPAA and GDPR), could result in additional costs and liabilities or inhibit sales of our products and services. • If our security measures, or those of our third-party providers, are breached or unauthorized access to personal information or other private or proprietary data is otherwise obtained, our software may be perceived as not being secure, customers may reduce or terminate their use of our products and services, and we may face litigation, regulatory investigations, significant liability and reputational damage. • Unfavorable conditions in our industry or the global economy or reductions in information technology spending could limit our ability to grow our business and negatively affect our results of operations. • Economic and other disruptions from the global COVID-19 pandemic and its fallout may cause delays in our sales cycles, decrease sales to new customers, and reduce upselling and cross-selling to existing customers. • We may need to incur substantial costs to protect or defend our intellectual property rights, and any failure to adequately protect our intellectual property could reduce the value and attractiveness of our products and services. • The Proposed Business Combination transaction between MariaDB and Angel Pond is subject to significant risks and uncertainties, including the uncertainty that MariaDB will be able to agree with Angel Pond on definitive terms for the transaction, the risk that MariaDB's or Angel Pond's shareholders may not approve the transaction, and the risk that other conditions to closing (including required governmental, exchange and other approvals) may not be satisfied or waived, any of which could significantly affect an investment in MariaDB or Angel Pond. • Even if MariaDB and Angel Pond agree on definitive terms for the Proposed Business Combination and the transaction receives all applicable approvals, the exercise of redemption rights by Angel Pond's public shareholders may result in the failure of the transaction to close, or even if the transaction does close, such redemption could cause the combined company to be undercapitalized. • If the benefits of the Proposed Business Combination between MariaDB and Angel Pond do not meet expectations of investors or securities analysts, the market price of a combined company may decline, potentially significantly. • The costs relating to the transactions will be significant and there will be increased expenses and administrative burdens of being a public combined company, all of which could have a material impact on the business and the financial condition and results of the public combined company. • The unaudited financial information included in this presentation may not be indicative of what MariaDB's actual financial results or condition has been or will be. • The requirements of being a public company may strain our resources and divert management's attention, and the increases in legal, accounting and compliance exp than we anticipate. that will result from being a public company may be greater • As a private company, we have not been required to document and test our internal controls over financial reporting nor has our management been required to certify the effectiveness of our internal controls and our auditors have not been required to opine on the effectiveness of our internal control over financial reporting. Failure to maintain adequate financial, information technology and management processes and controls could impair our ability to comply with the financial reporting and internal controls requirements for publicly traded companies, which could lead to errors in our financial reporting and adversely affect our business.
