SUPPLEMENTAL PROXY STATEMENT INFORMATION

TEPPCO PARTNERS, L.P.
1100 Louisiana Street, 16^th Floor
Houston, Texas 77002

October 9, 2009

Dear TEPPCO Unitholder:

You have previously received a proxy statement/prospectus dated September 8, 2009 (the “Proxy Statement”) and related proxy materials soliciting your vote in connection with the special meeting of our unitholders to be held on Friday, October 23, 2009. The following letter is to provide TEPPCO unitholders with supplemental information related to the proposed merger. We are pleased to inform you that the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 has expired.

The following supplemental information is also being provided to TEPPCO unitholders in connection with a proposed resolution of objections raised by M. Lee Arnold and Sharon Olesky to the proposed settlement of a derivative action filed by Peter Brinckerhoff in the Court of Chancery of New Castle County, Delaware (the “Derivative Action”) and a putative class action also filed by Peter Brinckerhoff and Rene Horowitz, as attorney in fact for Rae Kenrow, also filed in the same court (the “Merger Action”), as well as the potential resolution of claims made by the plaintiffs in class action suits filed in the 129th Judicial District of the District Court of Harris County Texas, Cause No. 2009-41231, and in the 11th Judicial District of the District Court of Harris County Texas, Cause No. 2009-41626. As previously disclosed, a hearing regarding approval of the Settlement Agreement in the Derivative Action and the Merger Action has been scheduled for October 12, 2009.

In consideration for Arnold and Olesky’s agreement to withdraw their objections to the settlement of the Derivative Action and Merger Action, as embodied in a Stipulation to Withdraw Objections executed on October 7, 2009, and without admitting the merits of their objections, TEPPCO makes the following supplemental disclosures in connection with and by reference to the Proxy Statement. The following additional disclosure is made to add to the Proxy Statement:

1. insert as the third and fourth sentences to the first paragraph under “Unaudited Financial Projections of Enterprise and TEPPCO” on page 61:

As discussed further under “The Merger Parties’ Businesses — Enterprise’s Business — Relationship of Enterprise and TEPPCO with EPCO and Affiliates,” management of both Enterprise GP and TEPPCO GP are employees of EPCO, Inc. Accordingly, EPCO employees participated in the creation of the financial projections for TEPPCO as well as for Enterprise.

2. insert as the third sentence to the first paragraph under “Discounted Cash Flow Analysis” on page 68:

To calculate the applicable implied exchange ratio reference range, Credit Suisse used discount rates based on TEPPCO’s and Enterprise’s estimated cost of equity capital and terminal yields based on a variety of factors influencing current, historical and potential future trading differentials for Enterprise common units and TEPPCO units.

3. insert as the fifth sentence to the second paragraph under “Brinckerhoff Litigation Matters” on page 76:

In addition, the amended complaint refers to the fact that the TEPPCO ACG Committee had retained an independent investment banking firm to, among other things, issue a fairness opinion in connection with the Jonah Gas Gathering Company joint venture, but the firm did not deliver an opinion with respect to the transaction.

Your vote is important. The deadline for voting by telephone or through the Internet is 11:59 p.m. Eastern Daylight Time on Thursday, October 22, 2009, the night before the special meeting. If you need assistance with casting or changing your vote, please call our proxy solicitor, Georgeson Inc., at (888) 264-7035 or TEPPCO’s Investor Relations department at (800) 659-0059.

Best Regards,

/s/ Jerry E. Thompson
