Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included in this Current Report on Form 8-K that address activities, events or developments that the ~~Partnership~~Company expects, believes or anticipates will or may occur in the future are forward-looking statements. Without limiting the generality of the foregoing, forward-looking statements contained in this Current Report on Form 8-K specifically include the expectations of plans, strategies, objectives and anticipated financial and operating results of the ~~Partnership~~Company, including the ~~Partnership~~Company’s drilling program, production, derivative instruments, capital expenditure levels and other guidance included in this Current Report on Form 8-K, as well as the impact of the novel coronavirus 2019 (“COVID-19”) pandemic on the ~~Partnership~~Company’s operations. These statements are based on certain assumptions made by the ~~Partnership~~Company based on management’s experience and perception of historical trends, current conditions, anticipated future developments and other factors believed to be appropriate. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the ~~Partnership~~Company, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. These include, but are not limited to, risks that the proposed transaction may not be consummated or the benefits contemplated therefrom may not be realized, the ability to obtain requisite regulatory and unitholder approval and the satisfaction of the other conditions to the consummation of the proposed transaction, the ability of Crestwood to successfully integrate the Partnership’s operations and employees and realize anticipated synergies and cost savings, the potential impact of the announcement or consummation of the proposed transaction on relationships, including with employees, suppliers, customers, competitors and credit rating agencies, changes in crude oil and natural gas prices, developments in the global economy, particularly the public health crisis related to the COVID-19 pandemic and the adverse impact thereof on demand for crude oil and natural gas, the outcome of government policies and actions, including actions taken to address the COVID-19 pandemic and to maintain the functioning of national and global economies and markets, the impact of the Partnership’s actions to protect the health and safety of employees, vendors, customers, and communities, weather and environmental conditions, the timing of planned capital expenditures, availability of acquisitions, uncertainties in estimating proved reserves and forecasting production results of the Partnership’s customers, operational factors affecting the commencement or maintenance of producing wells of the Partnership’s customers, the condition of the capital markets generally, as well as the Partnership’s ability to access them, and uncertainties regarding environmental regulations or litigation and other legal or regulatory developments affecting the Partnership’s business and other important factors that could cause actual results to differ materially from those projected as described in the Partnership’s reports filed with the U.S. Securities and Exchange Commission (the “SEC”). Additionally, the unprecedented nature of the COVID-19 pandemic and the related decline of the oil and gas exploration and production industry may make it particularly difficult to identify risks or predict the degree to which identified risks will impact the Partnership’s business and

~~financial~~2 condition. Because considerable uncertainty exists with respect to the future pace and extent of a global economic recovery from the effects of the COVID-19 pandemic, the Partnership cannot predict whether or when crude oil production and economic activities will return to normalized levels. Any forward-looking statement speaks only as of the date on which such statement is made and the Partnership undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law.
