This communication may contain certain forward-looking statements within the meaning of the federal securities laws with respect to the proposed transaction between PubCo, MBSC, Greenfire and the other parties thereto.

Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this communication, including but not limited to: (i) the timing to complete the proposed business combination by MBSC’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by MBSC; (ii) the occurrence of any event, change or other circumstances that could give rise to the termination of the definitive agreements relating to the proposed business combination; (iii) the outcome of any legal, regulatory or governmental proceedings that may be instituted against PubCo, MBSC, Greenfire or any investigation or inquiry following announcement of the proposed business combination, including in connection with the proposed business combination; (iv) the inability to complete the proposed business combination due to the failure to obtain approval of MBSC’s stockholders or the inability to receive approval of the proposed plan of arrangement in connection with the proposed business combination; (v) Greenfire’s and PubCo’s success in retaining or recruiting, or changes required in, its officers, key employees or directors following the proposed business combination; (vi) the ability of the parties to obtain the listing of PubCo’s common shares and warrants on the New York Stock Exchange upon the closing of the proposed business combination; (vii) the risk that the proposed business combination disrupts current plans and operations of Greenfire; (viii) the ability to recognize the anticipated benefits of the proposed business combination; (ix) unexpected costs related to the proposed business combination; (x) the amount of redemptions by MBSC’s public stockholders being greater than expected; (xi) the management and board composition of PubCo following completion of the proposed business combination; (xii) limited liquidity and trading of PubCo’s securities; (xiii) geopolitical risk and changes in applicable laws or regulations; (xiv) the possibility that Greenfire or MBSC may be adversely affected by other economic, business, and/or competitive factors; (xv) operational risks; (xvi) the possibility that the COVID-19 pandemic or another major disease disrupts Greenfire’s business; (xvii) litigation and regulatory enforcement risks, including the diversion of management time and attention and the additional costs and demands on Greenfire’s resources; (xix) the risks that the consummation of the proposed business combination is substantially delayed or does not occur; (xx) risks associated with the oil and gas industry in general (e.g., operational risks in development, exploration and production; disruptions to the Canadian and global economy resulting from major public health events, the Russian-Ukrainian war and the impact on the global economy and commodity prices; the impacts of inflation and supply chain issues and steps taken by central banks to curb inflation; pandemic, war, terrorist events, political upheavals and other similar events; events impacting the supply and demand for oil and gas including the COVID-19 pandemic and actions taken by the OPEC + group; delays or changes in plans with respect to exploration or development projects or capital expenditures); (xxi) the uncertainty of reserve estimates; (xxii) the uncertainty of estimates and projections relating to production, costs and expenses; (xxiii) health, safety and environmental risks; (xxiv) commodity price and exchange rate fluctuations; (xxv) changes in legislation affecting the oil and gas industry; (xxvi) uncertainties resulting from potential delays or changes in plans with respect to exploration or development projects or capital expenditures; and (xxvii) the risk that the Potential Refinancing is unsuccessful or does not occur.
