(1)	These shares were received in connection with a corporate reorganization completed prior to the closing of the Issuer's initial public offering described in the prospectus dated December 14, 2011, in which Laredo Petroleum, LLC ("Laredo LLC") merged with the Issuer, with the Issuer being the surviving entity. In accordance with the limited liability company agreement of Laredo LLC, the reporting person received common stock of the Issuer in exchange for his vested and unvested units in Laredo LLC. The number of shares that the reporting person received was based on the value that the reporting person would have received under the distribution provisions of the Laredo LLC agreement upon a liquidation of Laredo LLC at a liquidation value determined by reference to the initial offering price. To the extent any such units were subject to vesting requirements, the common stock issued in exchange therefor is also subject to such requirements.
(2)	The price to the public at the time of purchase.
