Cautionary Note Regarding Hydrocarbon Quantities

The SEC permits oil and gas companies, in their filings with the SEC, to disclose only proved reserves that a company has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions, and on an optional basis, probable and possible reserves meeting SEC definitions and criteria. The Company does not include probable and possible reserves in its SEC filings. This presentation includes information concerning probable reserves quantities compliant with PRMS/SPE guidelines and related PV-10 values that are different from quantities of such non-proved reserves that may be reported under SEC rules and guidelines. In addition, this presentation includes Company estimates of resources and "EURs" or "economic ultimate recoveries" that are not necessarily reserves because no specific development plan has been committed for such recoveries. Recovery of estimated probable reserves and estimates of resources and EUR's and recoverable resources, are inherently more speculative than recovery of proved reserves.

PV-10 of reserves includes projected revenues, estimated production costs and estimated future development costs. Unless otherwise stated, PV-10 excludes cash flows for asset retirement obligations, general and administrative expenses, derivatives, debt service and income taxes.

Standardized measure or the PV-10 from our proved or 2P oil and natural gas reserves should not be viewed as representative of the current market value of our estimated oil and natural gas reserves.

Non-GAAP Measures

This presentation includes certain financial measures that are not calculated in accordance with U.S. generally accepted accounting principles ("GAAP"). These measures include (i) Net Debt, (ii) Adjusted EBITDA and (iii) Free Cash Flow. These non-GAAP financial measures are not measures of financial performance prepared or presented in accordance with GAAP and may exclude items that are significant in understanding and assessing our financial results. Therefore, these measures should not be considered in isolation, and users of any such information should not place undue reliance thereon. Please refer to the slides titled "Non-GAAP Reconciliations" under the Appendix to this presentation for a reconciliation of these measures to the most directly comparable GAAP measures and WTI's definitions (which may be materially different than similarly titled measures used by other companies) of these measures as well as certain additional information regarding these measures. WTI believes the presentation of these metrics may be useful to investors because it supplements investors' understanding of its operating performance by providing information regarding its ongoing performance that excludes items it believes do not directly affect its core operations.

WHY WE HAVE LIKED THE GULF OF MEXICO FOR 40 YEARS

GOM Provides Better Porosity and Permeability than the Unconventionals

Multiple stacked pay opportunities

• Offer attractive primary production and recompletion opportunities
• Provide multiple targets improving chance of success when drilling

Natural drive mechanisms generate incremental production from 2P reserves

• High quality sandstones have drive mechanisms superior to depletion drive alone
• Enjoy incremental reserve adds, partly due to how reserve quantities are booked or categorized under SEC guidelines
