State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

TransAtlantic Petroleum Corp. (the “Company”) is unable to file its Quarterly Report on Form 10-Q for the quarter ended March 31, 2009 (the “Form 10-Q”), because the Company has simultaneously been preparing its Form 10-Q and engaging in activities related to its recent acquisition of Incremental Petroleum Limited (“Incremental”). The Company requires additional time to ensure the filing of a complete and accurate Form 10-Q and allow the Company’s independent registered public accountants to complete its review. The Company expects to file the Form 10-Q within the period described under Rule 12b-25(b)(2).

Exhibit A

to

Form 12b-25

Part IV, Item (3)

The Company anticipates that its Form 10-Q for the three months ended March 31, 2009 will contain results of operations that reflect a significant change from the corresponding period in 2008, due to the Company’s recent acquisitions of Incremental and Longe Energy Limited, and its resulting change in operations. The Company cannot reasonably estimate results of operations to be reported in the Form 10-Q until it finalizes the preliminary purchase price allocation for the acquisition of Incremental.
