Issuance and Sale of Senior Notes

On April 5, 2013, RAAM Global Energy Company (the “Company”) entered into a purchase agreement (the “Purchase Agreement”), by and among the Company, the Guarantors (as defined below) and Global Hunter Securities, LLC (the “Initial Purchaser”), which provided for the sale by the Company of $50,000,000 aggregate principal amount of its 12.50% Senior Secured Notes due 2015 (the “Notes”) to the Initial Purchaser (the “Offering”).

The summary of the Purchase Agreement set forth in this Item 1.01 does not purport to be complete and is qualified by reference to such agreement, a copy of which is being filed as Exhibit 10.1 hereto and is incorporated herein by reference.

On April 11, 2013, the Company successfully completed the Offering. The Notes are Additional Notes issued pursuant to an indenture dated as of September 24, 2010 (the “Base Indenture”), by and among the Company, the Guarantors (as defined below) and the Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), pursuant to which the Company initially issued $150 million aggregate principal amount of its 12.50% Notes on September 24, 2010 and an additional $50 million aggregate principal amount of its 12.50% Notes on July 15, 2011 (collectively, the “Existing Notes”), as supplemented by the First Supplemental Indenture dated as of July 15, 2011 (the “First Supplemental Indenture”), the Second Supplemental Indenture dated as of April 11, 2013 (the “Second Supplemental Indenture”) and the Third Supplemental Indenture dated as of April 11, 2013 (the “Third Supplemental Indenture,” and together with the Base Indenture, First Supplemental Indenture and the Second Supplemental Indenture, the “Indenture”). The Notes have identical terms, other than the issue date and issue price, and constitute part of the same series as the Existing Notes, although they bear a different CUSIP number than the Existing Notes until they are no longer restricted securities under the Securities Act (as defined below). The Additional Notes are jointly and severally, and unconditionally, guaranteed (the “Guarantees”) on a senior secured basis by all of the Company’s current and future domestic subsidiaries that guarantee the indebtedness under the Company’s amended revolving credit facility entered into on November 29, 2011 (collectively, the “Guarantors”).

The Notes and the Guarantees rank (i) senior in right of payment to all of the Company’s and the Guarantors’ future subordinated indebtedness, (ii) equal in right of payment with all of the Company’s and the Guarantors’ existing and future senior indebtedness, including indebtedness under such senior credit facility and the initially issued notes, and (iii) effectively junior to indebtedness under such senior credit facility and additional permitted first lien indebtedness to the extent of the value of the collateral securing such senior credit facility and such additional permitted first lien indebtedness.

The Notes and the Guarantees were offered and sold in private transactions in accordance with Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) and to non-U.S. persons pursuant to, and in accordance with, Regulation S under the Securities Act. The Notes and Guarantees have not been registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.

The purchase price for the Notes and Guarantees was 103.000% of their principal amount, plus accrued interest from April 1, 2013. The Company received net proceeds from the issuance and sale of the Notes of approximately $50.3 million (after underwriting fees and estimated offering expenses. The Company intends to use the net proceeds from the offering to repay existing indebtedness under the Company’s revolving credit facility and for general corporate purposes.

Interest on the Notes accrues from and including April 1, 2013 at a rate of 12.500% per year. Interest on the Notes is payable semi-annually in arrears on April 1 and October 1 of each year, commencing on October 1, 2013. The Notes mature on October 1, 2015.

The Indenture contains covenants that, among other things, limit the Company’s ability and the ability of certain of its subsidiaries to:

At any time before October 1, 2014, the Company, at its option, may redeem up to 35% of the aggregate principal amount of the Notes issued under the Indenture with the net cash proceeds of one or more qualified equity offerings at a redemption price of 112.50% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to the date of redemption, as long as:
