Underwriting Agreement

On December 7, 2012, QR Energy, LP (the "Partnership"), QRE GP, LLC and QRE Operating, LLC entered into an Underwriting Agreement (the "Underwriting Agreement") with RBC Capital Markets, LLC, Barclays Capital Inc., J.P. Morgan Securities LLC, UBS Securities LLC, Wells Fargo Securities, LLC, Raymond James & Associates, Inc., Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC and Goldman, Sachs & Co., as representatives of the several underwriters named therein (the "Underwriters"), with respect to the offering and sale of 12,000,000 common units representing limited partner interests in the Partnership (the "Common Units") to be sold by the Partnership at a price to the public of $16.24 per Common Unit ($15.5904 per Common Unit, net of underwriting discounts). The Partnership also granted the Underwriters an option for a period of 30 days to purchase up to an additional 1,800,000 Common Units from the Partnership (together with the Firm Units, the "Units"). On December 10, 2012, the Underwriters exercised in full their option to purchase the additional 1,800,000 Common Units. The material terms of the offering of the Units are described in the prospectus, dated December 7, 2012, as filed by the Partnership with the Securities and Exchange Commission (the "Commission") on December 10, 2012. The offer and sale of the Units was registered with the Commission pursuant to a registration statement on Form S-3 (Registration No. 333-181820). Closing with respect to the Units is expected to occur on December 12, 2012, subject to the satisfaction of customary closing conditions.

The Underwriting Agreement contains customary representations, warranties and agreements of the Partnership, and customary conditions to closing, indemnification rights, obligations of the parties and termination provisions. Furthermore, the officers and directors of the Partnership's general partner have agreed with the Underwriters not to offer or sell any Common Units (or securities convertible into or exchangeable for Common Units), subject to customary exceptions, for a period of 45 days after the date of the Underwriting Agreement without the prior written consent of RBC Capital Markets, LLC.

The Underwriters may, from time to time, engage in transactions with and perform services for the Partnership and its affiliates in the ordinary course of business for which they may receive customary fees and reimbursement of expenses. Additionally, affiliates of certain of the Underwriters are lenders under the Partnership's credit facility and accordingly will receive substantially all of the net proceeds from the offer and sale of the Units.

The foregoing description of the Underwriting Agreement is qualified in its entirety by reference to the Underwriting Agreement, a copy of which is filed herewith as Exhibit 1.1 and is incorporated herein by reference.

On December 7, 2012, the Partnership issued a press release announcing that it had priced the offering of the Units. On December 11, 2012, the Partnership issued a press release announcing the Underwriters' exercise in full of their option to purchase additional Common Units. Copies of these press releases are furnished as Exhibits 99.1 and 99.2, respectively.

The information being furnished pursuant to Item 7.01 of this Form 8-K and in Exhibits 99.1 and 99.2 shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934 (the "Exchange Act") or otherwise subject to the liabilities of that Section, nor shall they be deemed incorporated by reference in any registration statement or other filing under the Securities Act of 1933 or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

The opinions of Vinson & Elkins L.L.P. are filed herewith as Exhibits 5.1 and 8.1 and are incorporated herein by reference.
