Item 1.01               Entry into a Material Definitive Agreement.

On May 16, 2013, Emerald Oil, Inc. (the “Company”) entered into an Underwriting Agreement (the “Underwriting Agreement”) with Canaccord Genuity Inc. and Johnson Rice & Company L.L.C., as representatives of the several underwriters named therein (collectively, the “Underwriters”), pursuant to which the Company will sell 12,000,000 shares of its common stock, par value $0.001 per share (“Common Stock”) at a public offering price of $6.10 per share. The Underwriters were also granted an over-allotment option for a period of 30 days to purchase up to a maximum of 1,800,000 additional shares of the Common Stock from the Company. The material terms of the offering of the shares of Common Stock are described in the prospectus supplement dated May 17, 2013, as filed by the Company with the Securities and Exchange Commission (the “Commission”). The offer and sale of the shares of Common Stock were registered with the Commission pursuant to a Registration Statement on Form S-3 (File No. 333-184430), and the closing is expected to occur on May 22, 2013.

The Company intends to use the net proceeds from this offering of approximately $69.2 million (after deducting underwriting discounts and commissions and estimated offering expenses) and the net proceeds from any exercise of the underwriters’ option to purchase additional shares of Common Stock, along with cash on hand and the proceeds from its concurrent private placement with White Deer Energy, cash flow from operations, proceeds from the sale of assets and additional borrowings under the credit facility, to fund its capital budget in 2013. Any remaining net proceeds will be used for general corporate purposes, including working capital.

The Underwriters and their affiliates have performed investment and commercial banking and advisory services for the Company and its affiliates from time to time for which they have received customary fees and expenses. The Underwriters and their affiliates may, from time to time, engage in transactions with and perform services for the Company in the ordinary course of their business.

The Underwriting Agreement contains customary representations, warranties and agreements of the Company, and customary conditions to closing, indemnification rights, obligations of the parties and termination provisions. The foregoing description of the Underwriting Agreement is qualified in its entirety by reference to such Underwriting Agreement, a copy of which is filed herewith as Exhibit 1.1 and is incorporated herein by reference.

Item 7.01               Regulation FD Disclosure.

On May 17, 2013, the Company issued a press release entitled “Emerald Oil, Inc. Announces Pricing of Upsized Public Offering of Common Stock.” A copy of the press release is attached hereto as Exhibit 99.1 and incorporated herein by reference.
