Current Net Sales and Şelmo Field Extension

TransAtlantic's current net sales are approximately 5,300 BOEPD, comprised of
approximately 3,850 BOPD and approximately 8.8 MMCFPD. Oil sales increased 38%
from the Company's April 2014 average as a result of production increases in
the Şelmo and Arpatepe fields. The Company is currently developing the
southeastern portion of the Şelmo field, which is less developed than the
northwestern portion of the field. The Arpatepe-7 well (50% working interest)
had initial production of 330 BOPD gross (165 BOPD net).

TransAtlantic was also granted a new ten-year extension to its Şelmo field
production lease from the General Directorate of Petroleum Affairs of the
Republic of Turkey.

Chairman and Chief Executive Officer N. Malone Mitchell 3^rd commented, "Once
again, Turkey has shown itself to be a valuable partner and a supporter of
domestic oil and natural gas production. We are very pleased to extend our
Şelmo lease for another ten years and look forward to making additional
investments in Turkey."

Note on BOE

Barrels of oil equivalent, or BOE, are derived by the Company by converting
natural gas to oil in the ratio of six thousand cubic feet ("MCF") of natural
gas to one barrel of oil. A BOE conversion ratio of six MCF to one barrel is
based on an energy equivalency conversion method primarily applicable at the
burner tip and does not represent a value equivalency at the wellhead. BOE may
be misleading, particularly if used in isolation.
