8 II. Strategic Plan

9 Operating Plan for Current Environment: PRESERVE FAVORABLE LIQUIDITY PROFILE  September re-affirmation of $165 million fully conforming Borrowing Base  Ended 6/30/15 $108 million drawn  Limit “growth” capital expenditures LOWER OPERATING EXPENSES  Shut in marginal production and optimize portfolio  Allocate budget to investments that lower production costs  Curtail and optimize G&A where necessary ECONOMICIALLY GROW AND PRESERVE INVENTORY  Preserve future growth outlook by continuing to run the Bakken drilling rig  Delay stimulations until commodity prices stabilize WAIT FOR THE RIGHT DEAL  Lots of distress on the market – wait for the right deal in the right area  Any deal must 1. Not stress the balance sheet and 2. Be accretive Operating Plan for Current Environment

10 III. Financial Overview

11 Abraxas’ Reserve Conservatism Example: Seaport Global recently conducted a study titled “Perception versus Reality.” In this report Seaport Global compared actual results to projected well results. Abraxas scored in the top three of actual results versus projections…for the industry. (1) Seaport Global June 18, 2015.

12 Where We Stand Today….. Financially Sound  Recently re-affirmed fully conforming Borrowing Base of $165 million  Calculated by banks using a more conservative price deck and an advance rate  2Q15 interest averaged approximately 2.43% interest on this line  No sub-debt, preferreds, etc. leads to easily calculable and significant residual equity value  Exited June 30, 2015 1.4x Debt/EBITDA (1)  High margin, oil weighted production base  2Q15 standard netback of $21.51/boe (2) and total cash netback of $15.73/boe (3)  Expect to continue improve costs and margins through well and G&A curtailments Economic Development Plan  Current plan is to continue to develop Bakken/Three Forks with Company owned rig  Current economics generate a 19.6% ROR (4)  Uses conservative type curve that Company is beating  Boast a large inventory of conventional projects where economics work at current commodity prices  Currently permitting wells in the Powder River Basin Porcupine area HBP Inventory for the Future  Eagle Ford all but a portion of the significant Eagle Ford inventory is HBP  Additional Chalk/Buda potential in South Texas  Gas upside in the Edwards and West Texas  EOR potential at Portilla  Powder River Basin stacked horizontal and refrac potential  Second Bench Three Forks Despite How Our Stock Is Trading… (1) Debt includes RBL facility. EBITDA calculated as Revenue – Realized Hedge Settlements – LOE – Production Taxes – Cash G&A – Other Expenses. Does not include EBITDA contribution from Raven Drilling. Please see appendix for EBITDA reconciliation. (2) Standard Netback calculated as Revenue – LOE – Production Taxes (3) Total Netback calculated as Revenue – LOE – Production Taxes – Cash G&A (4) ROR calculated using strip pricing as of 9/28/15 with trailing twelve month differentials as of 6/30/15 and assumes a $6.3 million completed well cost.

40 Standardized Measure Reconciliation PV-10 is the estimated present value of the future net revenues from our proved oil and gas reserves before income taxes discounted using a 10% discount rate. PV-10 is considered a non-GAAP financial measure under SEC regulations because it does not include the effects of future income taxes, as is required in computing the standardized measure of discounted future net cash flows. We believe that PV-10 is an important measure that can be used to evaluate the relative significance of our oil and gas properties and that PV-10 is widely used by securities analysts and investors when evaluating oil and gas companies. Because many factors that are unique to each individual company impact the amount of future income taxes to be paid, the use of a pre-tax measure provides greater comparability of assets when evaluating companies. We believe that most other companies in the oil and gas industry calculate PV-10 on the same basis. PV-10 is computed on the same basis as the standardized measure of discounted future net cash flows but without deducting income taxes. The following table provides a reconciliation of PV-10 to the standardized measure of discounted future net cash flows at December 31, 2014: Total Proved 31-Dec-14 Future Gross Revenue $2,946,483 Production and Ad Valorem Taxes (278,791) Operating Expenses (613,162) Capital Costs (551,591) Abandonment Costs (5,654) Future Net Revenue 1,497,285 Present Worth at 10 Percent 637,443 Present value of future income taxes discounted at 10% (147,907) Standardized measure of discounted future net cash flows $489,536
