FORWARD LOOKING STATEMENTS; non-gaap Outlooks, projections, estimates, targets and business plans in this presentation or any related subsequent discussions are forward-looking statements. Actual future results, including TransAtlantic Petroleum Ltd.’s own production growth and mix; financial results; the amount and mix of capital expenditures; resource additions and recoveries; finding and development costs; project and drilling plans, timing, costs, and capacities; revenue enhancements and cost efficiencies; industry margins; margin enhancements and integration benefits; and the impact of technology could differ materially due to a number of factors. These include market prices for natural gas, natural gas liquids and oil products; estimates of reserves and economic assumptions; the ability to produce and transport natural gas, natural gas liquids and oil; the results of exploration and development drilling and related activities; economic conditions in the countries and provinces in which we carry on business, especially economic slowdowns; actions by governmental authorities, receipt of required approvals, increases in taxes, legislative and regulatory initiatives relating to fracture stimulation activities, changes in environmental and other regulations, and renegotiations of contracts; political uncertainty, including actions by insurgent groups or other conflict; the negotiation and closing of material contracts; shortages of drilling rigs, equipment or oilfield services; and other factors discussed here and under the heading “Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2016, which is available on our website at www.transatlanticpetroleum.com and at www.sec.gov. See also TransAtlantic’s audited financial statements and the accompanying management discussion and analysis. Forward-looking statements are based on management’s knowledge and reasonable expectations on the date hereof, and we assume no duty to update these statements contained in our Form 10-K as of any future date. The information set forth in this presentation does not constitute an offer, solicitation or recommendation to sell or an offer to buy any securities of the Company. The information published herein is provided for informational purposes only. The Company makes no representation that the information and opinions expressed herein are accurate, complete or current. The information contained herein is current as of the date hereof, but may become outdated or subsequently may change. Nothing contained herein constitutes financial, legal, tax, or other advice. The SEC requires oil and gas companies, in their filings with the SEC, to disclose 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. We may use the terms “estimated ultimate recovery,” “EUR,” “probable,” “possible,” and “non-proven” reserves, “prospective resources” or “upside” or other descriptions of volumes of resources or reserves potentially recoverable through additional drilling or recovery techniques. These estimates are by their nature more speculative than estimates of proved reserves and accordingly are subject to substantially greater risk of actually being realized by the Company. There is no certainty that any portion of estimated prospective resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the estimated prospective resources. This presentation includes certain non-GAAP financial measures, including Adjusted EBITDAX and Adjusted Book Value. While the Company believes Adjusted EBITDAX and Adjusted Book Value are useful measures for investors, they are not presented in accordance with GAAP. You should not consider non-GAAP measures in isolation or as a substitute for items calculated in accordance with GAAP. In addition, Adjusted EBITDAX has inherent material limitations as a performance measure because it adds back certain expenses to net income from continuing operations, resulting in those expenses not being taken into account in the applicable financial measure. Because not all companies use identical calculations, the presentation herein of non-GAAP financial measures may not be comparable to other similarly titled measures of other companies. Note on PV-10: The present value of estimated future net revenues or PV-10 is an estimate of future net revenues from a property at the date indicated, without giving effect to derivative financial instrument activities, after deducting production and ad valorem taxes, future capital costs, abandonment costs and operating expenses, but before deducting future federal income taxes. The future net revenues have been discounted at an annual rate of 10% to determine their “present value.” The present value is shown to indicate the effect of time on the value of the net revenue stream and should not be construed as being the fair market value of the properties or the oil and natural gas reserves we own. Estimates have been made using constant oil and natural gas prices and operating and capital costs at the date indicated, at its acquisition date, or as otherwise indicated. We believe that the present value of estimated future net revenues before income taxes, while not a financial measure in accordance with GAAP, is an important financial measure used by investors and independent oil and natural gas producers for evaluating the relative significance of oil and natural gas properties and acquisitions because the tax characteristics of comparable companies can differ materially. PV-10 is not a measure of financial or operating performance under GAAP. PV-10 should not be considered as an alternative to the Standardized Measure as defined under GAAP. The Standardized Measure represents the PV-10 after giving effect to income taxes. Note on BOE: BOE (barrel of oil equivalent) is derived by converting natural gas to oil in the ratio of six thousand cubic feet (MCF) of natural gas to one barrel (bbl) of oil. BOE may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf:1 bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.

Adjusted Book Value is a non-GAAP financial measure. Adjusted Book Value is defined as shareholders equity plus deferred income taxes, accumulated other comprehensive loss and asset retirement obligations. The Company believes that Adjusted Book Value is a useful measure to investors in comparing the shareholders equity of the Company without the effects of foreign currency valuation changes, asset retirement obligations and certain future deferred income taxes. The following table reconciles Adjusted Book Value to the most directly comparable GAAP financial measure, which is shareholders equity. Market value- adjusted book value Adjusted Book Value is higher than reflected by U.S. GAAP Accounting Rules. Our Deferred Tax Liability of $18.8mm as of December 31, 2016 consists primarily of two components. The first is the anticipated future cash tax costs which will occur as the result of accelerating tax deductions for well development costs that have been capitalized for our financial statements. The second is a reserve for future withholding taxes that would be incurred if our earnings in Turkey were distributed. Unlike the U.S. where unlimited lease terms are the norm, in Turkey and Bulgaria, when the term of the lease is over, the state oil company buys the leasehold equipment and assumes remediation responsibility. For U.S. GAAP Accounting, this liability is estimated at $4.8mm on a discounted basis as of December 31, 2016. U.S. GAAP procedures require the Company to increase or decrease the value of its assets and liabilities quarterly reflecting the changes in foreign currency exchange values. While this is logical for foreign currency denominated assets or liabilities (i.e., cash balances, AR, AP, notes, etc.,) (including minor assets such as furniture or vehicles), it does not accurately reflect real world changes in the value of oil and gas properties, which are sold and valued in U.S. dollars throughout much of the world, including Turkey. The Turkish Lira has depreciated significantly against the U.S. dollar and our accumulated other comprehensive loss resulting from this devaluation is an accumulated loss of $140.3mm as of December 31, 2016.

Bulgaria – North Koynare Prospect *Reserves are internal estimates for gross reserves. A A’ B B’ R1 R2 1400 Acres When the original Koynare #1 well was drilled by Direct Petroleum, it was located utilizing old 2D seismic and crossed a major fault encountering the primary target several thousand feet low to prognosis. This zone, locally known as the Dolni Dabnik is the primary producing zone in this area. When perforated, the Koynare well flowed water at 6,000bpd. Subsequent 3D seismic shot by TransAtlantic identified the location of the fault and a four way closure located north of the existing wells. Volumetric reserves (to spill point) of this structure given the porosity and thickness in the #1 well are approximately 100 mmbbl (if all fluid) with approximately 30 mmbbl recoverable from primary production methods (internal estimates). TransAtlantic intends to redrill the #1 well from approximately 10,000’ to directionally encounter the 3D structure approximately 1,600’ NE of the current well. If productive, the well would be completed with a deviated or horizontal wellbore. The reservoir is conducive to high rate natural completion. Several additional 2D leads are present on the 165,000 acre production license. Success on Koynare #1 would lead to acquiring 3D Seismic over the entire license.

Adjusted ebitdax reconciliations Adjusted EBITDAX from continuing operations ("Adjusted EBITDAX") is a non-GAAP financial measure that represents net income (loss) from continuing operations plus interest and other, net, current and deferred income tax expense, exploration, abandonment and impairment, seismic and other exploration expense, foreign exchange loss (gain), share-based compensation expense, loss (gain) on commodity derivative contracts, cash settlements on commodity derivative contacts, accretion of asset retirement obligation, depreciation, depletion and amortization, revaluation of contingent consideration, commodity derivative unwind (gain) /loss and net other items. The Company believes Adjusted EBITDAX assists management and investors in comparing the Company's performance on a consistent basis without regard to depreciation, depletion and amortization and impairment of oil and natural gas properties and exploration expenses, which can vary significantly from period to period. In addition, management uses Adjusted EBITDAX as a financial measure to evaluate the Company's operating performance.   Adjusted EBITDAX is not a measure of financial performance under GAAP. Accordingly, it should not be considered as a substitute for net income or income from continuing operations prepared in accordance with GAAP. Net income or income from continuing operations may vary materially from Adjusted EBITDAX. Investors should carefully consider the specific items included in the computation of Adjusted EBITDAX.
