See Item 8.01 of this Current Report on Form 8-K with respect to the Agreement and Plan of Merger between GulfWest Energy Inc., a Texas corporation ("GulfWest"), and the Registrant, formerly GulfWest's wholly-owned subsidiary, Crimson Exploration Inc., a Delaware corporation ("Crimson"). Item 8.01 Other Events. On June 29, 2005, GulfWest merged with and into Crimson for the purpose of changing GulfWest's state of incorporation from Texas to Delaware (the "Reincorporation"). The Reincorporation was accomplished pursuant to an Agreement and Plan of Merger, dated June 28, 2005, which was approved by GulfWest's shareholders at the 2005 Annual Shareholders' Meeting held June 1, 2005, a copy of which is attached hereto as Exhibit 3.1 and incorporated herein by reference. As a result of the Reincorporation, each share of GulfWest common stock was converted into one corresponding and substantially identical share of Crimson common stock, and each share of each series of GulfWest preferred stock was converted into one corresponding and substantially identical share of such series of Crimson preferred stock. All outstanding options, warrants and other rights outstanding at the time of the Reincorporation entitled to receive upon exercise or conversion shares of GulfWest common stock now represent the right to receive an identical number of shares of Crimson common stock. Each certificate representing shares of capital stock of GulfWest now represents the same number and kind of shares of capital stock of Crimson. Crimson common stock initially traded on the Over-the-Counter Bulletin Board under GulfWest's symbol, "GULF," but began trading under the symbol "CXPI" on July 1, 2005. Crimson issued a press release regarding the Reincorporation on June 30, 2005, which is attached as Exhibit 99.1 and incorporated herein by reference. Pursuant to Rule 12g-3(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the common stock of Crimson, par value $0.001 per share ("Common Stock"), is deemed to be registered under Section 12(g) of the Exchange Act. Crimson's currently effective certificate of incorporation (including certificates of designation, preferences and rights of Crimson's preferred stock), bylaws and form of stock certificate for the Common Stock are attached hereto as Exhibits 3.1-3.6, 3.7 and 3.8, respectively. 2 Item 9.01 Financial Statements and Exhibits.
