Forward-Looking Statements Certain statements in this Presentation may be considered forward-looking statements. Forward-looking statements generally relate to future events or MDH’s or the Company’s future financial or operating performance. For example, projections of future Adjusted EBITDA and other metrics are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may”, “should”, “expect”, “intend”, “will”, “estimate”, “anticipate”, “believe”, “predict”, “potential” or “continue”, or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by MDH and its management, and the Company and its management, as the case may be, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of negotiations and any subsequent definitive agreements with respect to the Business Combination; (2) the outcome of any legal proceedings that may be instituted against MDH, the combined company or others following the announcement of the Business Combination and any definitive agreements with respect thereto; (3) the inability to complete the Business Combination due to the failure to obtain approval of the shareholders of MDH, to obtain financing to complete the Business Combination or to satisfy other conditions to closing; (4) changes to the proposed structure of the Business Combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the Business Combination; (5) the ability to meet stock exchange listing standards following the consummation of the Business Combination; (6) the risk that the Business Combination disrupts current plans and operations of the Company as a result of the announcement and consummation of the Business Combination; (7) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (8) costs related to the Business Combination; (9) changes in applicable laws or regulations; (10) the possibility that the Company or the combined company may be adversely affected by other economic, business, and/or competitive factors; (11) the Company’s estimates of expenses and profitability; and (12) other risks and uncertainties set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in MDH’s final prospectus relating to its initial public offering dated February 1, 2021. Nothing in this Presentation should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Neither MDH nor the Company undertakes any duty to update these forward-looking statements. Use of Projections This Presentation contains financial forecasts with respect to the Company’s projected financial results, including Revenue and Adjusted EBITDA, for the Company's fiscal years 2021 through 2023. The Company's independent auditors have not audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections should not be relied upon as being necessarily indicative of future results. The assumptions and estimates underlying the prospective financial information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. All projections and estimates included in this presentation are approximations. This includes annualized information where the results from a month are converted to a full year even though such monthly results may not be indicative of the results the Company would achieve for a full year.

Disclaimer (continued) Financial Information; Non-GAAP Financial Measures Certain of the financial information and data contained in this Presentation is unaudited and does not conform to Regulation S-X. In addition, this Presentation includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, Net Premium, EBITDA, Adjusted EBITDA, Adjusted Gross Profit and certain ratios and other metrics derived therefrom. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that are significant in understanding and assessing the Company’s financial results. Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP. You should be aware that the Company’s presentation of these measures may not be comparable to similarly-titled measures used by other companies. The Company believes these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company’s financial condition and results of operations. The Company believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing the Company’s financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. Please refer to footnotes where presented on each page of this Presentation or to page 33 of this Presentation for a reconciliation of these measures to what the Company believes are the most directly comparable measure evaluated in accordance with GAAP. This Presentation also includes certain projections of non-GAAP financial measures. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward-looking non-GAAP financial measures is included. Industry and Market Data In this Presentation, MDH and the Company rely on and refer to certain information and statistics obtained from third-party sources which they believe to be reliable. Neither MDH nor the Company has independently verified the accuracy or completeness of any such third-party information.

Summary of Risks Certain Risks Related to OP Group Holdings, LLC All references to the “Company,” “Olive.com,” “PayLink,” “Olive,” “we,” “us” or “our” in this presentation refer to the business of OP Group Holdings, LLC and its subsidiaries. The risks presented below are certain of the general risks related to the Company’s business, industry and ownership structure and are not exhaustive. The list below is qualified in its entirety by disclosures contained in future filings by the Company, or by third parties (including MDH Acquisition Corp.) with respect to the Company, with the United States Securities and Exchange Commission (“SEC”). These risks speak only as of the date of this presentation and we make no commitment to update such disclosure. The risks highlighted in future filings with the SEC may differ significantly from and will be more extensive than those presented below. Risks Related to Our Business Our quarterly and annual results may fluctuate and may not fully reflect the underlying performance of our business. The business and industry in which we operate is highly competitive, and we may be unable to compete successfully with our current or future competitors. Some of our competitors have greater financial, technological and other resources than we currently possess. Failure by protection plan administrators to accurately and timely pay customer claims or otherwise provide high-quality service for our customers could affect our ability to retain our existing customers and attract new ones. Our vehicle and consumer product protection payment plan finance business may involve a higher risk of delinquency or collection than other lending operations and could expose us to losses. A decline in the economy in general could have an adverse impact on our operating results by reducing the number of customers purchasing vehicle and consumer product protection plans. Our success and our ability to grow our business depend on retaining and expanding our customer base. If we fail to add new customers or retain current customers, our business, revenue, operating results and financial condition could be harmed. Maintaining and enhancing our Olive brand and reputation is critical to our growth, and if we are not able to maintain and enhance our brand, our business, results of operations and financial condition could be adversely affected. Our limited operating history for Olive makes it difficult to evaluate our current Olive business performance, implementation of our business model and our future prospects. Our Olive business has experienced rapid growth since inception which may not be indicative of our future growth and, if we continue to grow rapidly, we may not be able to manage our growth effectively. Increases in the Prime Interest Rate may reduce the profitability of our payment plan business. Changes in insurance, consumer protection and related regulations may adversely affect our business. Insurance company and protection plan administrator insolvency may cause us losses. Aggressive marketing by our competitors may adversely affect our business. We may experience cash flow problems due to delays or other disruptions in receiving proceeds from our credit facility or under the terms of our payment plan finance documentation. Our ability to grow our complementary product and service offerings may be limited, which could negatively impact our growth rate and financial performance. If we are unable to expand our product offerings to additional affinity partners, our prospects for future growth may be adversely affected. Our proprietary data analytics algorithms may not operate properly or as we expect them to, which could cause us or our insurance partners to write vehicle and consumer product protection plans we or they should not write or price those plans inaccurately. Regulators may limit our ability to expand or implement our Olive product and/or may eliminate or restrict the confidentiality of our proprietary technology, which could have a material adverse effect on our Olive financial condition and results of operations. 38

Summary of Risks (continued) Risks Related to Our Business (continued) We rely on data analytics and our Olive digital platform to collect data points that we evaluate in pricing our vehicle and consumer product protection plans and customer support, and improving business processes, and any legal or regulatory requirements that restrict our ability to collect this data could thus materially and adversely affect our Olive business, financial condition, results of operations and prospects. We rely on traffic to our platform to grow revenue, and if we are unable to drive traffic cost-effectively, it could adversely affect our business, results of operations and financial condition. We depend on search engines, social media platforms, content-based advertising and other online sources to attract consumers to our Olive website which may be affected by third-party interference beyond our control, and as we grow our customer acquisition costs will continue to rise. We may require additional capital to grow our business, which may not be available on terms acceptable to us or at all. We are subject to payment processing risk. Interruptions or delays in the services provided by our Internet service providers could impair the operability of our Olive and PayLink websites and may cause our business to suffer. Security incidents or real or perceived errors, failures or bugs in our systems or Olive and PayLink websites could impair our operations, result in loss of personal customer information, damage our reputation and brand, and harm our business and operating results. We collect, process, store, share, disclose and use customer information and other data, and our actual or perceived failure to protect such information and data, respect customers’ privacy or comply with data privacy and security laws and regulations could damage our reputation and brand and harm our business and operating results. We employ third-party licensed software for use in our business, and the inability to maintain these licenses, errors in the software we license or the terms of open source licenses could result in increased costs or reduced service levels, which would adversely affect our business. We may be unable to prevent or address the misappropriation of our data. Our business depends on attracting and retaining key management and talent, including our Founder, and the loss of any key personnel or ability to attract additional highly-qualified personnel could adversely affect our business, results of operations and financial condition. If our customers were to claim that the vehicle or consumer product protection plans they purchased failed to provide adequate or appropriate coverage, we could face claims that could harm our business, results of operations and financial condition. Our company culture has contributed to our success and if we cannot maintain this culture as we grow, our business could be harmed. Our growth depends in part on the success of our strategic relationships with third parties and our failure to successfully maintain, grow and manage these relationships could harm our business. If we or our insurance and administrator partners are unable to underwrite vehicle and consumer product protection plan risks accurately and charge competitive yet profitable rates to our customers, our business, results of operations and financial condition will be adversely affected. Our exposure to cancellation activity and regulation may be greater in California where we currently have most of our Olive customers. Litigation or investigations involving us, including third-party intellectual property infringement claims, could result in material settlements, fines or penalties and may adversely affect our business, financial condition and results of operations. Failure to protect or enforce our intellectual property rights could harm our business, results of operations and financial condition. Recent U.S. tax legislation, including the Tax Cuts and Jobs Act, may materially adversely affect our financial condition, results of operations and cash flows. Our expansion within the United States and any future international expansion strategy will subject us to additional costs and risks and our plans may not be successful. Cybersecurity incidents could disrupt our business or result in the loss of critical and confidential information. 39

Summary of Risks (continued) Our future revenue growth and prospects depend on attaining greater market share. Our decision to expand existing service offerings into new markets or to launch new service offerings may consume significant financial and other resources and may not achieve the desired results. The coverage afforded under our insurance policies may be inadequate for the needs of our business or our third-party insurers may be unable or unwilling to meet our coverage requirements, which could adversely affect our business, results of operations, and financial condition. If our existing customers cease to do business with us or reduce the amount of their business, our revenues and gross margins will be harmed and we will be required to spend more money to grow our customer base. We may acquire other companies or technologies or be the target of strategic transactions, which could divert our management’s attention, result in additional dilution to our stockholders and otherwise disrupt our operations and harm our operating results. Severe weather events, pandemics and other catastrophes, including the effects of climate change, are inherently unpredictable and may have a material adverse effect on our financial results and financial condition. The direct to consumer vehicle protection plan business, including the market for vehicle service contracts and similar products by related names, is historically dependent upon new vehicle sales, which could adversely affect our business. Our failure to comply with certain industry regulations, including those promulgated under the Truth-in-Lending Act, could result in fines, sanctions or other adverse consequences. Adverse regulations applicable to the payment processing, consumer finance and insurance industries may restrict our ability to expand or to operate our business as we wish and may expose us to fines and other penalties. The increasing adoption by states of cybersecurity regulations could impose additional compliance burdens on us and expose us to additional liability. We expect our results of operations to fluctuate on a quarterly and annual basis. In addition, our operating results and operating metrics are subject to seasonality and volatility, which could result in fluctuations in our quarterly revenues and operating results or in perceptions of our business prospects. We along with our insurance partners rely on data from our customers for pricing our vehicle and consumer product protection plan products. The lack of availability or inaccuracy of data could limit the functionality of our products and disrupt our Olive business. If we fail to prevent actual or perceived disruptions to or defects in our digital platform or similar incidents, such as privacy or data security breaches or other security incidents, site outages, payment disruptions or other incidents that impact the reliability of our services, we may experience damage to our brand and reputation, material financial penalties, or other legal liabilities, along with a decline in use of our platform, which would adversely affect our business, results of operations and financial condition. We utilize a significant amount of indebtedness in the operation of our business. Our inability to comply with the terms of any of our secured credit facilities may adversely affect our business and, in some limited instances, result in recourse to us when the value of the assets securing the facility are insufficient to cover the amounts owed to the lenders. Our results of operations and financial condition may be adversely affected due to limitations in the analytical models used to assess and predict our exposure to cancellations. 40
