Prior to the Issuer’s initial public offering (the “IPO”), the Issuer was a wholly owned subsidiary of Midstates Petroleum Holdings, LLC (“MPH”). MPH was a wholly owned subsidiary of Midstates Petroleum Holdings, Inc. (the “S-Corp”). Each of Stephen McDaniel, John Foley, John Crum, Guy Matthew David, Dexter Burleigh, and Curtis Newstrom owned shares of common stock of the S-Corp (collectively, the “S-Corp Shareholders”). In 2008, FR Midstates Holdings LLC (“FRMH”), an affiliate of Interholding, acquired common units of Midstates Petroleum Holdings LLC (“MPH”) in connection with a reorganization of a predecessor to MPH. Each of Stephen Pugh, Thomas Mitchell and James Hart (together, the “MPH Management Members”) acquired common units in MPH in 2011.

On April 24, 2012, prior to the closing of the IPO, the Issuer completed a corporate reorganization (the “Reorganization”), pursuant to a Master Reorganization Agreement (the “Master Agreement”), dated April 24, 2012. In accordance with the Master Agreement, (i) Interholding contributed its interest in FRMH and MPH to the Issuer in exchange for Common Stock, (ii) each MPH Management Member contributed his or her interest in MPH in exchange for Common Stock, and (iii) the S-Corp merged with and into Issuer pursuant to an Agreement and Plan of Merger, pursuant to which all of the outstanding common stock of S-Corp held by the S-Corp Shareholders was exchanged for Common Stock.

The acquisitions of Common Stock by the Reporting Persons were undertaken for investment purposes. The Reporting Persons also intend to participate in and influence the affairs of the Issuer through exercise of their rights to appoint directors to the Issuer’s Board of Directors (pursuant to the Stockholder Agreement, described in Item 6) and through their voting rights with respect to all of their shares of Common Stock.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis and, depending upon the price of and other market conditions relating to the Common Stock or other securities of the Issuer, subsequent developments affecting the Issuer, the Issuer’s business and prospects, other investment and business opportunities available to the Reporting Persons, general stock market and economic conditions, tax considerations, and other factors deemed relevant, may decide to increase or decrease the size of their investment in the Issuer.

Except as set forth in this Item 4, the Reporting Persons do not have any specific plans or proposals that relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D.

(a) To the best knowledge of the Reporting Persons, as of April 25, 2012, there were 66,420,332 shares of Common Stock outstanding. The Reporting Persons, comprising a “group” within the meaning of Section 13(d)(3) of the Exchange Act of 1934 and for purposes of qualifying the Issuer as a “controlled company” pursuant to the rules of the New York Stock Exchange, beneficially own in the aggregate 34,546,175 shares of Common Stock (the “Subject Shares”), comprised of 27,147,651 shares of Common Stock beneficially owned by the First Reserve Filers and held in a brokerage account, and an aggregate of 7,398,524 shares of Common Stock directly owned by the Management Filers. Collectively, the Reporting Persons beneficially own 52% of the total outstanding shares of Common Stock. The First Reserve Filers beneficially own 40.9%, and the Management Filers, collectively, beneficially own 11.1%, of the total outstanding shares of Common Stock.

(b) Due to the relationship between Interholding and each of the Management Filers as set forth in the Stockholders Agreement (described in Item 6), each of Interholding and the Management Filers may be deemed to beneficially own the Subject Shares. GP LLC, as the general partner of Interholding, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Subject Shares. GP XII LP, as the managing member of GP LLC, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Subject Shares. GP Limited, as the general partner of GP XII LP, may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose or direct the disposition of) the Subject Shares. By virtue of Mr. Macaulay’s right to appoint a majority of the directors of GP Limited, Mr. Macaulay may be deemed to have the shared power to vote or direct the vote of (and the shared power to dispose of or direct the disposition of) the Subject Shares, and therefore, Mr. Macaulay may be deemed to be a beneficial owner of the Subject Shares.

(c) On April 24, 2012, the Issuer completed the Reorganization pursuant to which Interholding and each of the Management Filers received shares of Common Stock of the Issuer. On April 25, 2012, pursuant to an Underwriters Agreement, dated April 19, 2012, among the Issuer, the Selling Stockholders named therein, and the Underwriters named therein, Interholding sold 9,402,470 shares of Common Stock at $12.22 per share for an aggregate consideration of $114,898,183.40, Dexter Burleigh sold 8,824 shares of Common Stock at $12.22 per share for an aggregate consideration of $107,829.28, and Guy Matthew David sold 26,889 shares of Common Stock at $12.22 per share for an aggregate consideration of $328,583.58.
