On February 5, 2013, Genesis Energy, L.P.

The Purchase Agreement provides for, among other things, the issuance and sale by the Issuers of $350 million in aggregate principal amount of 5 ³/₄% senior unsecured notes due 2021 (the “Notes”). The offer and sale of the securities has not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and unless so registered, such securities may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The securities were offered and issued only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act.

The Purchase Agreement provides that the obligations of the initial purchasers to purchase the Notes were subject to receipt of legal opinions by counsel and to other customary conditions. The initial purchasers were obligated to purchase all the Notes if they purchased any of the Notes. The Issuers and the Guarantors have agreed to indemnify the initial purchasers against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the initial purchasers may be required to make because of any of those liabilities.

The Issuers intend to use the net proceeds from the Notes offering to repay outstanding borrowings under the Partnership’s revolving credit facility and for general partnership purposes.

The Purchase Agreement contains representations, warranties and other provisions that were made or agreed to, among other things, to provide the parties thereto with specified rights and obligations and to allocate risk among them. Accordingly, the Purchase Agreement should not be relied upon as constituting a description of the state of affairs of any of the parties thereto or their affiliates at the time it was entered into or otherwise.

A copy of the Purchase Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated into this Item 2.03 by reference. The description of the Purchase Agreement contained herein is qualified in its entirety by the full text of such exhibit.

From time to time, the initial purchasers and their affiliates have provided, or may in the future provide, various investment banking, commercial banking, financial advisory, brokerage and other services to the Partnership and its affiliates for which services they have received, and may in the future receive, customary fees and expense reimbursement. In addition, affiliates of the initial purchasers are lenders under the Partnership’s revolving credit facility.

The Issuers will have the option to redeem the Notes, in whole or in part, at any time on or after February 15, 2017, at the redemption prices (expressed as percentages of principal amount) of 102.875% for the twelve-month period beginning on February 15, 2017, 101.438% for the twelve-month period beginning on February 15, 2018 and 100.000% beginning on February 15, 2019 and at any time thereafter, together with any accrued and unpaid interest to, but not including, the date of redemption.

Furthermore, before February 15, 2016, the Issuers may on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes with the net proceeds of certain public or private equity offerings at a redemption price of 105.750% of the principal amount of Notes, plus any accrued and unpaid interest, if any, to the date of redemption, if at least 65% of the aggregate principal amount of the Notes issued under the Indenture remains outstanding immediately after such redemption and the redemption occurs within 120 days of the closing date of such equity offering. The Issuers may also be required to make an offer to purchase the Notes upon a change of control.
