FORWARD - LOOKING STATEMENTS. This presentation contains forward - looking statements that are subject to risks and uncertainties. All statements other than statements of historical fact or relating to present facts or current conditions included in this presentation are forward - looking statements. Forward - looking statements include, but are not limited to, statements regarding projections, estimates and forecasts of revenue and other financial and performance metrics, projections of market opportunity and expectations, the estimated implied enterprise value of the combined company, Core Scientific's ability to scale and grow its business, source clean and renewable energy, the advantages and expected growth of the combined company, the combined company's ability to source and retain talent, the cash position of the combined company following closing, XPDI's and Core Scientific's ability to consummate the Transaction, and expectations related to the terms and timing of the Transaction. You can identify forward - looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate,” “estimate,” “expect,” “project,” “seek,” “plan,” “intend,” “believe,” “will,” “may,” “could,” “continue,” “likely,” “should,” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events but not all forward - looking statements contain these identifying words. These forward - looking statements are subject to a number of risks and uncertainties, including risks related to mining equipment supply, the sufficiency of infrastructure, including electricity sources, the price of bitcoin, the global hash rate and other risks identified as “risk factors” later in this presentation, the parties may be unable to successfully or timely consummate the proposed business combination, including the risk that any regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the stockholders of the Company or XPDI is not obtained; failure to realize the anticipated benefits of the proposed business com bination; and those factors discussed in XPDI’s final prospectus filed with the SEC on February 11, 2021 under the heading “Risk Factors” and other documents XPDI has filed, or will file, with the SEC. The forward - looking statements in this presentation are based on assumptions that the Company and XPDI have made in light of their industry experience and their perceptions of historical trends, current conditions, expected future developments and other factors that they believe are appropriate under the circumstances. You should understand that these statements are not guarantees of performance or results. These assumptions and the combined company’s future performance or results involve risks and uncertainties (many of which are beyond the Company’s and XPDI’s control). Additional factors or events that could cause the combined company’s actual performance to differ from these forward - looking statements may emerge from time to time, and it is not possible for the Company or XPDI to predict all of them. Should one or more of these risks or uncertainties materialize, or should any of the assumptions prove incorrect, the combined company’s actual financial condition, results of operations, future performance and business may vary in material respects from the performance projected in these forward - looking statements. This presentation, including any forward - looking statement made by the Company and XPDI within, speaks only as of the date on which it is made. The Company and XPDI undertake no obligation to publicly update this presentation, whether as a result of new information, future developments or otherwise, except as may be required by law. Market data and industry information used throughout this presentation are based on the knowledge of the industry and the good faith estimates of the Company’s management. The Company and XPDI also relied, to the extent available, upon the review of independent industry surveys and other publicly available information prepared by a number of third - party sources. All of the market data and industry information used in this presentation involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. Although the Company and XPDI believe these sources are reliable, they cannot guarantee the accuracy or completeness of this information, and they have not independently verified this information. This presentation contains the Company’s projected financial and operational information. Such projected financial and operational information is forward - looking and is for illustrative purposes only. The information should not be relied upon as being indicative of future results. Projections, assumptions and estimates of the Company’s future performance and the future performance of the industry in which the Company operates are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including, among other things, the sufficiency of infrastructure, including electricity sources, the price of bitcoin, the global hash rate and the shipment of manufacturers’ units on a timely basis. The Company’s management believes the projections and underlying assumptions have a reasonable basis as of the date of this presentation, but there can be no assurance that these projections will be realized or that actual results will not be significantly higher or lower than projected. The inclusion of such projections or historical financial and operational information in this presentation should not be regarded as a representation by any person that the results reflected in such projections will be achieved or that historical results will be indicative of future performance. FINANCIAL INFORMATION; NON - GAAP FINANCIAL MEASURES. Certain financial information and data contained in this presentation is unaudited and does not conform to Regulation S - X promulgated under the Securities Act of 1933, as amended. Accordingly, such financial information may be adjusted in or may be presented differently in, the proxy statement/prospectus or registration statement to be filed by XPDI with the SEC. This presentation also includes non - GAAP financial measures, including Adjusted EBITDA. XPDI and the Company believe that 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's management uses certain of these non - GAAP measures to compare the Company's performance to that of prior periods for trend analyses and for budgeting and planning purposes. Not all of the information necessary for a quantitative reconciliation of these forward - looking non - GAAP financial measures to the most directly comparable GAAP financial measures is available without unreasonable efforts at this time. Specifically, the Company does not provide such quantitative reconciliation due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. The material has been prepared or is distributed solely for information purposes and is not a proxy statement, an offer to sell, a solicitation or an offer to buy or a recommendation to purchase any security or instrument or to participate in any trading strategy. No offer of securities shall be made except by means of a prospectus meeting the requirements of the Securities Act of 1933, as amended. Note 1: Presentation assumes pro forma Core Scientific, including the acquisition of Blockcap, which is expected to close on July 22, 2021, and Blockcap’s acquisition of Radar Relay, which closed on July 2, 2021.

Our 20x multiple is a ~4x multiple premium to our MARA target multiple – we believe RIOT should trade at a slight premium given its diversified revenue streams (Whinstone) and existing hosting capacity. We note that Bitcoin miners have exhibited high volatility and are highly correlated to the price of Bitcoin. Our assumptions assume a $35K Bitcoin price through our forecast period and a 2022E global hash rate of ~235 EH/s.” – Compass Point Research & Trading, LLC, 7/15/21 1.

RISK FACTORS ® 33 PROPRIETARY & CONFIDENTIAL

RISK FACTORS (1/6) The below list of key risks has been prepared solely for the purposes of potential investors evaluating the the proposed Business Combination, and not for any other purpose. Unless the context otherwise requires, all reference in this subsection to the "Company," "Core Scientific," "we," "us" or "our" refer to the business of Core Scientific and its subsidiaries (including Blockcap, the acquisition of which is expected to be completed on July 22, 2021) prior to the consummation of the Business Combination. The risks presented below are some of the general risks to the business sand operations of Core Scientific following completion of the Business Combination. You should carefully consider these risks and uncertainties and should carry out your own diligence and consult with your own financial and legal advisors concerning the risks and suitability of an investment in this Company or XPDI before making an investment decision. Risks relating to the business of Core Scientific will be disclosed in future documents filed or furnished with the U.S. Securities and Exchange Commission (the "SEC"), including documents filed or furnished in connection with the proposed transaction between XPDI and Core Scientific. The risks presented in such filings will be consistent with those that would be required for a public company in SEC filings and may differ significantly from and be more extensive than those presented below. These risk factors are not exhaustive, and investors are encouraged to perform their own investigation with respect to the business, financial condition and prospects of Core Scientific following the completion of the Business Combination. Investors should carefully consider the following risk factors in addition to the information included in the investor presentation. Core Scientific may face additional risks and uncertainties that are not presently known to it, or that it currently deems immaterial, which may also impair Core Scientific's business or financial condition. ® 34 PROPRIETARY & CONFIDENTIAL Risks Related to Core Scientific’s Business and Industry 1. Our business is highly dependent on a small number of digital currency mining equipment suppliers. 2. A slowdown in the demand for blockchain/artificial intelligence (“AI”) technology or blockchain/AI hosting resources and other market and economic conditions could have a material adverse effect on our business, financial condition and results of operations. 3. We have an evolving business model and a limited history of generating revenue from our services. In addition, our evolving business model, and our expansion into new lines of business or derivatives such as DeFi, increases the complexity of our business, which could have a material adverse effect on our business, financial condition and results of operations. 4. Our limited operating history and rapidly evolving industry makes it difficult for us to evaluate our future business prospects and the failure to do so accurately could have a material adverse effect on our business, financial condition and results of operations. 5. Our businesses are capital intensive and failure to obtain the necessary capital when needed may force us to delay, limit or terminate our expansion efforts or other operations, which could have a material adverse effect on our business, financial condition and results of operations.

6. Changes in tariffs, import or export restrictions, Chinese regulations or other trade barriers could have a material adverse effect on our business, financial condition and results of operations. 7. Our historical financial results may not be indicative of our future performance and our inability to obtain adequate funding could have a material adverse effect on our business, financial condition and results of operations. 8. Substantially all of our assets are pledged to our senior secured lender and failure to repay obligations to our senior lender when due will have a material adverse effect on our business and could result in foreclosure on our assets. 9. Our revenue comes from a small number of customers, and the loss of, or significant decrease in business from, any number of these customers or the failure to continually attract new customers could have a material adverse effect on our business, financial condition and results of operations. 10. Delays in the expansion of existing hosting facilities or the construction of new hosting facilities or significant cost overruns could have a material adverse effect on our business, financial condition and results of operations. 11. The coronavirus outbreak has had, and may continue to have, a material adverse impact on our business, liquidity, financial condition and results of operations. 12. We are subject to risks associated with our need for significant electrical power and the limited availability of power resources, which could have a material adverse effect on our business, financial condition and results of operations. 13. Governments and government regulators may potentially restrict the ability of electricity suppliers to provide electricity to hosting and transaction processing operations such as ours, which could have a material adverse effect on our business, financial condition and results of operations. 14. Power outages in our hosting facilities could have a material adverse effect on our business, financial condition and results of operations. 15. Our success depends in large part on our ability to mine for digital assets profitably and to attract customers for our hosting capabilities. Increases in power costs, inability to mine digital assets efficiently and to sell digital assets at favorable prices will reduce our operating margins, impact our ability to attract customers for our services may harm our growth prospects and could have a material adverse effect on our business, financial condition and results of operations. 16. If we do not accurately predict our hosting facility requirements, it could have a material adverse effect on our business, financial condition and results of operations. ® 35 PROPRIETARY & CONFIDENTIAL RISK FACTORS (2/6)

17. We may not be able to compete effectively against our current and future competitors, which could have a material adverse effect on our business, financial condition and results of operations. 18. If the award of digital assets for solving blocks and transaction fees for recording transactions are not sufficiently high to incentivize miners, miners may cease expending hash rate to solve blocks and confirmations of transactions on the blockchain could be slowed temporarily. A reduction in the hash rate expended by miners on any digital asset network could increase the likelihood of a malicious actor obtaining control in excess of fifty percent (50%) of the aggregate hash rate active on such network or the blockchain, potentially permitting such actor to manipulate the blockchain in a manner that adversely affects our business, financial condition, and results of operations. 19. If we fail to accurately estimate the factors upon which we base our contract pricing, we may generate less profit than expected or incur losses on those contracts, which could have a material adverse effect on our business, financial condition and results of operations. 20. Any failure in the critical systems of our hosting facilities or services we provide could lead to disruptions in our and our customers’ businesses and could harm our reputation and result in financial penalty and legal liabilities, which would reduce our revenue and have a material adverse effect on our business, financial condition and results of operations. 21. We generate significant revenue from a limited number of hosting facilities in Kentucky, Georgia and North Carolina and a significant disruption to operations in these region could have a material adverse effect our business, financial condition and results of operations. 22. Currently, there is relatively small use of digital assets in the retail and commercial marketplace in comparison to relatively large use by speculators, thus contributing to price volatility that could adversely affect our business, financial condition, and results of operations. 23. Concerns about greenhouse gas emissions and global climate change may result in environmental taxes, charges, assessments or penalties and could have a material adverse effect on our business, financial condition, and results of operations. 24. If we do not successfully close or integrate acquisitions or strategic partnerships (including the pending acquisition of Blockcap), we may not realize the anticipated benefits of any such acquisitions or partnerships, which could have a material adverse effect on our business, financial condition and results of operations. 25. Latency in confirming transactions on a network could result in a loss of confidence in the network, which could have a material adverse effect on our business, financial condition and results of operations. 26. If we are not able to successfully anticipate, invest in, or adopt technological advances in our industry, it could have a material adverse effect on our business, financial condition and results of operations. ® 36 PROPRIETARY & CONFIDENTIAL RISK FACTORS (3/6)

27. We may not be able to adequately protect our intellectual property rights and other proprietary rights, which could have a material adverse effect on business, financial condition and results of operations. 28. Significant or unexpected changes to our transaction processing operations may have a material adverse effect on our business, financial condition and results of operations. 29. A reduction in the processing power expended by transaction processors on a network could increase the likelihood of a malicious actor or botnet obtaining control, which could have a material adverse effect on our business, financial condition and results of operations. 30. Transaction processing operators may sell a substantial amount of digital assets into the market, which may exert downward pressure on the price of the applicable digital asset, and in turn, could have a material adverse effect on our business, financial condition and results of operations. 31. The “halving” of rewards available on the Bitcoin network, or the reduction of rewards on other networks, has had and in the future could have a negative impact on our ability to generate revenue and could have a material adverse effect on our business, financial condition and results of operations. 32. From time to time we have sold, and we may sell in the future, a portion of our digital assets to pay for costs and expenses, which has reduced, and may continue to reduce, the amount of digital assets we hold and thus prevents us from recognizing any gain from the appreciation in value of the digital assets we have sold and may sell in the future. 33. Digital assets are subject to extreme price volatility. The value of digital assets is dependent on a number of factors, any of which could have a material adverse effect on our business, financial condition and results of operations. 34. The loss or destruction of a private key required to access a digital asset is irreversible, we also may temporarily lose access to our digital assets. 35. Intellectual property rights claims may adversely affect the operation of any or all of the networks. 36. The patent applications we have filed may not result in issued patents, and our issued patents may not provide meaningful protection, may be challenged, and may prove difficult to enforce. 37. A soft or hard fork on a network could have a material adverse effect on our business, financial condition and results of operations. 38. The digital assets held by us may be subject to loss, damage, theft or restriction on access, which could have a material adverse effect on our business, financial condition or results of operations. 39. The digital assets held by us are not subject to FDIC or SIPC protections. ® 37 PROPRIETARY & CONFIDENTIAL RISK FACTORS (4/6)

40. As more processing power is added to a network, our relative percentage of total processing power on that network is expected to decline absent significant capital investment, which has an adverse impact on our ability to generate revenue from processing transactions on that network and could have a material adverse effect on our business, financial condition and results of operations. 41. If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired. 42. We may acquire other businesses or receive offers to be acquired, which could require significant management attention, disrupt our business or dilute stockholder value. 43. An active trading market for our common stock may never develop or be sustained. 44. Our revenue may be negatively impacted by the inability or unwillingness of equipment manufacturers to deliver on our hardware orders in a timely manner. 45. We will incur costs and demands upon management as a result of complying with the laws and regulations affecting public companies in the United States, which may harm our business. 46. Digital assets such as Bitcoin may be regulated as securities or investment securities. 47. Since there has been limited precedent set for financial accounting or taxation of digital assets other than digital securities, it is unclear how we will be required to account for digital asset transactions and the taxation of our businesses. ® 38 PROPRIETARY & CONFIDENTIAL RISK FACTORS (5/6)

Risks Related to the Business Combination and the Combined Entity 48. The financial and operational projections related to the Company may not be realized, which may adversely affect the trading price of our common stock following the closing of the Business Combination. 49. The trading price of our common stock may be volatile, and you could lose all or part of your investment. 50. If you purchase our common stock in this private placement, you will incur immediate and substantial dilution in the book value of your investment. 51. Future sales and issuances of our capital stock or rights to purchase capital stock could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to decline. 52. We will have broad discretion in the use of net proceeds from this private placement and may invest or spend the proceeds in ways with which you do not agree and in ways that may not yield a return. 53. Substantial future sales of shares of our common stock could cause the market price of our common stock to decline. 54. Provisions in our corporate charter documents and under Delaware law may prevent or frustrate attempts by our stockholders to change our management or hinder efforts to acquire a controlling interest in us, and the market price of our common stock may be lower as a result. 55. Our common stock market price and trading volume could decline if securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business. 56. We are an “emerging growth company,” and we intend to comply only with reduced disclosure requirements applicable to emerging growth companies. As a result, our common stock could be less attractive to investors. 57. We do not intend to pay dividends for the foreseeable future. 58. The announcement of the proposed Business Combination could disrupt our relationships with its suppliers or other third parties. 59. We will incur significant transaction and transition costs in connection with the Business Combination. 60. We will be the only principal asset of XPDI following the Business Combination, and accordingly it will depend on distributions from us to pay taxes and expenses. 61. Fluctuations in operating results, quarter to quarter earnings and other factors, including negative media coverage, may result in significant decreases in the price of the combined company's securities. 62. Claims for indemnification by the combined company's directors may reduce its available funds to satisfy successful third - party claims against the combined company and may reduce the amount of money available to the combined company. ® 39 PROPRIETARY & CONFIDENTIAL RISK FACTORS (6/6)
