  Item 1.01. Entry into a Material Definitive Agreement.
  On April 5, 2013, Energy Transfer Partners, L.P. (the "Partnership") entered into an Underwriting Agreement (the "Underwriting Agreement") with Barclays Capital Inc. (the "Underwriter"), pursuant to which the Partnership agreed to sell to the Underwriter 13,800,000 common units (the "Units") representing limited partner interests in the Partnership (including 1,800,000 Units pursuant to the full exercise of the Underwriter's option to purchase additional Units) at a price of $47.58 per Unit (net of underwriting discounts and commissions in the amount of $0.47 per Unit). The Units have been registered under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to a Registration Statement on Form S-3ASR (File No. 333-171697) of the Partnership, as supplemented by the Prospectus Supplement dated April 5, 2013 relating to the Units, filed with the Securities and Exchange Commission ("Commission") pursuant to Rule 424(b) of the Securities Act on April 9, 2013. Legal opinions relating to the Units are included as Exhibits 5.1 and 8.1 hereto.
  The Underwriting Agreement contains customary representations, warranties and agreements by the Partnership, and customary conditions to closing, indemnification obligations of the Partnership and the Underwriter, including for liabilities under the Securities Act, other obligations of the parties and termination provisions. The summary of the Underwriting Agreement in this report does not purport to be complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is filed as Exhibit 1.1 hereto, and is incorporated herein by reference.
  The Underwriter may, from time to time, engage in transactions with and perform services for the Partnership and its affiliates in the ordinary course of business. An affiliate of the Underwriter is a lender under the Partnership's amended and restated revolving credit facility and, accordingly, will receive a portion of the net proceeds from this offering.
  Item 7.01. Regulation FD Disclosure.
  On April 5, 2013, the Partnership issued a press release announcing that it had priced the offering of the Units. A copy of the press release is furnished as Exhibit 99.1 hereto and is incorporated herein by reference.
  In accordance with General Instruction B.2 of Form 8-K, the information set forth in the attached Exhibit 99.1 is deemed to be "furnished" and shall not be deemed to be "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended.
