In addition, any statements that refer to projections, forecasts or other characterizations of future events or circumstances , i ncluding any underlying assumptions, are forward - looking statements. The forward - looking statements contained in this Presentation are based on Osprey’s and Royal’s current expectations and beliefs concerning future developments and their potential effects on Osprey and Royal. There can be no assu ran ce that future developments affecting us will be those that we have anticipated. These forward - looking statements involve a number of risks, un certainties (some of which are beyond Osprey’s or Royal’s control) or other assumptions that may cause actual results or performance to be materially di ffe rent from those expressed or implied by these forward - looking statements. A description of certain risks and uncertainties and factors that could cause actual results to differ materially from past r esu lts and future plans and projected and estimated future results can be found in Osprey’s Annual Report on Form 10 - K for the fiscal year ended December 31, 2017 and in subsequent reports on Form 10 - Q, including in the sections thereof captioned “Risk Factors” and “Cautionary Note Regarding Forward - Looking Statemen ts,” as well as in its subsequent reports on Form 8 - K, all of which are filed with the SEC and available free of charge at www.sec.gov.

RESERVE INFORMATION Reserve engineering is a process of estimating underground accumulations of hydrocarbons that cannot be measured in an exact way . The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions mad e b y reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previo usl y. If significant, such revisions could impact Osprey’s strategy and change the schedule of any further production and development drilling. Accordingly, rese rve estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered. Estimated Ultimate Recoveries, or “E URs ,” refers to estimates of the sum of total gross remaining proved reserves per well as of a given date and cumulative production prior to such given date f or developed wells. These quantities do not necessarily constitute or represent reserves as defined by the SEC and are not intended to be representativ e o f all anticipated future well results.
