Forward-Looking Statements and Risk FactorsThis presentation contains certain matters that may be considered “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, asamended, Section 21E of the Securities Exchange Act of 1934, including statements regarding the intent, belief or current expectations and projections of SamsonResources II, LLC (the “Company”) and its management. These statements can be identified by the use of forward-looking terminology, including “plan”, “intend”, “will”,“expect”, “anticipate”, “project”, “should”, “could” or other similar words. You are cautioned that any such forward-looking statements are not guarantees of futureperformance and are subject to a number of assumptions, risks and uncertainties many of which are beyond the control of the Company, its subsidiaries, or its and theirmanagement, representatives and advisors, that could materially and adversely affect actual results. These include risks relating to our financial performance andresults, our ability to improve our financial results and profitability following emergence from bankruptcy, our ability to complete pending asset sales, availability ofsufficient cash flow to execute our business plan, continued low or further declining commodity prices and demand for oil, natural gas and natural gas liquids, our abilityto hedge future production, our ability to replace reserves and efficiently develop current reserves, and the regulatory environment and other important factors thatcould cause actual results to differ materially from those anticipated or implied in the forward-looking statements and none of the Company, its subsidiaries, or its andtheir representatives and advisors undertake any obligation to update any such statements.

Reserve EstimatesThe SEC permits oil and natural gas companies, in their filings with the SEC, to disclose only proved, probable and possible reserves that meet the SEC’s definitions forsuch term. The Company may use terms in this presentation that the SEC’s guidelines strictly prohibit in SEC filings, such as “estimated ultimate recovery” or “EUR,”“resources,” “net resources,” “total resource potential” and similar terms to estimate oil and natural gas that may ultimately be recovered. These estimates are by theirnature more speculative than estimates of proved, probable and possible reserves as used in SEC filings and, accordingly, are subject to substantially greater uncertaintyof being actually realized. These estimates have not been fully risked by management. Actual quantities that may be ultimately recovered will likely differ substantiallyfrom these estimates. Factors affecting ultimate recovery include the scope of the Company’s actual drilling program, which will be directly affected by the availabilityof capital, drilling and production costs, commodity prices, availability of drilling services and equipment, lease expirations, transportation constraints, regulatoryapprovals, field spacing rules, actual drilling results and recoveries of oil and natural gas in place, and other factors. These estimates may change significantly as thedevelopment of properties provides additional data. These estimates may not be reflective of the Company’s current view of reserves.

PV-10PV-10 represents the present value, discounted at 10% per year, of estimated future net cash flows. The Company’s calculation of PV-10 herein differs from thestandardized measure of discounted future net cash flows determined in accordance with the rules and regulations of the SEC in that it is calculated before income taxes,rather than after income taxes. The Company’s calculation of PV-10 should not be considered as an alternative to the standardized measure of discounted future netcash flows determined in accordance with the rules and regulations of the SEC.

Adjusted EBITDAAdjusted EBITDA is defined as earnings before interest expense (net); income taxes; depreciation, depletion and amortization of oil and gas properties and otherproperty and equipment; impairment of oil and gas properties and other property and equipment; gains or losses on oil and gas properties and other property andequipment; accretion expense relating to asset retirement obligations; non-cash stock compensation and non-recurring expenses such as reorganization-related andrestructuring expenses; as well as excluding the impacts of the mark-to-market adjustments for derivatives. Adjusted EBITDA is not defined under GAAP and should notbe considered as an alternative measure of net income, cash flows or liquidity.

Powder River Basin

◼ Net Acres: ~150,000 (84% HBP)

◼ Current Prod: 2.7 MBoe/d (89% liquids)

◼ Locations: 2,470 gross

◼ Highly-economic stacked-pay oil resource with significant industry momentum applying modern completion and drilling designs.

II

13

Stacked Pay Provides Significant Upside

◼ The Powder River basin contains highly attractive stacked pays, which are present across the basin.

◼ Upper targets are oil-prone tight sands with higher permeability than shale plays and generally require less stimulation (lower capex) than shale resource plays.

◼ Primary conventional targets are the Parkman, Shannon, and Turner / Frontier formations.

◼ Meaningful development upside in the Niobrara and Mowry plays as industry participants de-risk these formations utilizing modern drilling and completion designs.

◼ Samson positioned in the core of emerging Niobrara and Mowry resource plays and Shannon, Frontier / Turner conventional plays.

─ 281 mi2 proprietary 3-D

─ Large, contiguous acreage block optimal for development

─ Industry best-in-class wells offsetting Samson position

◼ Active Rigs: 5

◼ Q2 ‘18 Net Prod.: 32 MBoe / day

◼ Net Acres: 256,000 net acres

“The Powder River Basin (PRB) in Wyoming is quickly establishing itself as the growth engine of the company, as recently demonstrated by a 78 percent increase in net production compared to the average 2017 fourth quarter rate.”

Douglas Lawler, CEO August 1, 2018

◼ Active Rigs: 1

◼ Q2 ‘18 Net Prod.: 17 MBoe / day

◼ Net Acres: 395,000 net acres

“We're seeing some very strong upsides for the Powder River Basin. We're looking at adding more rigs in the Powder River Basin.”

David Hager, CEOAugust 1, 2018

◼ Active Rigs: 3

◼ Net Acres: 400,000 net acres

“Yesterday afternoon we introduced two new premium plays in the Powder River Basin, demonstrating once again the value created by our leadership and exploration. Over the last few years, our Powder River Basin team has focused on understanding the geological complexities of our 400,000 net acre position. Like the Delaware Basin, the Powder River Basin is prolific, with almost a mile deep column of pay and multiple targets. And the Powder River Basin is now ready to become a meaningful contributor to EOG's future growth.”

David Trice, EVP, Exploration & ProductionAugust 3, 2018

◼ Q2 ‘18 Net Prod.: 17 MBoe / day

◼ Net Acres: ~415,000 net acres

“I am pleased this morning to begin discussing our appraisal efforts in Wyoming's Powder River Basin where we believe we have another onshore oil opportunity in its southern portion. As an emerging area of interest by industry, this part of the Powder has been receiving increased visibility.”

Al Walker, CEOAugust 1, 2018

➢ Samson’s 150,000 net acres are situated down the Powder River Basin’s geological axis and strategically located over the Shannon, Niobrara, Frontier / Turner, and Mowry formations.

− Overall, the Powder River Basin remains relatively underdeveloped horizontally, particularly in key Samson areas, but that is beginning to change with more rigs running across the basin and Samson’s acreage.

− Samson is aggressively pursuing State permitting activity to secure Operatorship and focus will be on the Shannon, Niobrara, Frontier / Turner and Mowry formations.

− Initiated 1 rig operated drilling program in 2018 that will target the Shannon, Niobrara, Frontier and Mowry formations.

(1) Reflects current industry density assumptions. Further down-spacing expected in the future.(2) Samson’s inventory is designed around 2-section lateral length wells, approximately 10,000’.(3) IRRs calculated using 08/01/2018 strip.

Samson Position in Powder River “Hot Spots”

CHK “Hot Spot”

NW Converse “Hot Spot”

Hummingbird “Hot Spot”

Mowry Shale Pressure Gradient Map– Deeper Depths = Higher BHP– Increased BHT = Higher BHP

▪ Subsurface Hot Spots in Basin result in higher than normal bottom hole temperatures (“BHT”) & pressures (“BHP”), thus resulting in higher IP30’s and Resource potential from over-pressured formations.

▪ Samson’s position is located in the deepest, hottest portion of PRB.

▪ Geological parameters, including T-Max, Ro, TOC, as well as BHT/BHP all contribute to greater Resource potential along deeper Powder River Basin geologic hotspots.
