Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

The stockholders of Triangle Petroleum Corporation (the “Company”) previously granted discretionary authority to the board of directors of the Company (the “Board”) to amend its Articles of Incorporation to effect a reverse stock split, pursuant to which existing shares of the Company’s common stock would be combined into new shares of the Company’s common stock at an exchange ratio between 1-for-3 and 1-for-10, with the exact exchange ratio and timing of the reverse stock split to be determined at the discretion of the Board. On November 2, 2010, the Board established the exchange ratio at 1-for-10. In connection with the reverse stock split, Board has decreased the number of shares of authorized common stock from 150,000,000 shares to 70,000,000. A copy of the Company’s Articles of Incorporation, as amended, are attached hereto as Exhibit 3.1. See Item 8.01 for further information.

On November 2, 2010, the Company received notice that, subject to the satisfaction of certain conditions, its common stock was authorized for listing on the NYSE Amex stock exchange. The listing of the Company’s common stock on the NYSE Amex is conditioned upon the Company’s completion of a 1-for-10 reverse stock split and of an offering of the Company’s common stock. The Company’s 1-for-10 reverse stock split will be effective for trading purposes on November 5, 2010 (the “Effective Date”) and the Company currently expects that shares of its common stock will begin trading on the NYSE Amex on the Effective Date, under the trading symbol “TPLM.” The Company can give no assurance that the condition related to the completion of the Company’s offering will be satisfied by this date or at all. The Company will delist from the OTC Bulletin Board once trading commences on the NYSE Amex.

The information in Item 7.01 of this Current Report is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section. The information in Item 7.01 of this Current Report shall not be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in any such filing. This release does not constitute an offer to sell, or the solicitation of an offer to buy, the Company’s common stock, nor will there be any sale of the Company’s common stock in any state or other jurisdiction in which such offer, solicitation or sale is not permitted.

On November 2, 2010, the Company received notification from the Financial Industry Regulatory Authority (“FINRA”) that the 1-for-10 reverse stock split previously approved by the Company’s stockholders will take effect on the Effective Date. Unless the Company’s common stock is then trading on NYSE Amex, on the Effective Date, the Company’s OTC Bulletin Board trading symbol will be changed from “TPLM” to “TPLMD” for approximately 20 business days after which it will revert to TPLM.
