TEPPCO Partners, L.P. (TPP)

Revolving Credit Facility

TEPPCO had in place a $700.0 million unsecured revolving credit facility, including the issuance of letters of credit (“Revolving Credit Facility”), which matured on December 13, 2011. On December 18, 2007, TEPPCO amended the Revolving Credit Facility (“Fifth Amendment”). The maturity date was extended to December 12, 2012, and the Fifth Amendment allows TEPPCO to request unlimited one-year extensions of the maturity date, subject to lender approval and satisfaction of certain other conditions. The Fifth Amendment contains an accordion feature whereby the total amount of the bank commitments may be increased, with lender approval and the

satisfaction of certain other conditions, from $700.0 million up to a maximum amount of $1.0 billion. The Fifth Amendment also increased the aggregate outstanding principal amount of swing line loans or same day borrowings permitted under the Revolving Credit Facility from $25.0 million to $40.0 million. The interest rate is based, at TEPPCO’s option, on either the lender’s base rate, or LIBOR rate, plus a margin, in effect at the time of the borrowings. The applicable margin with respect to LIBOR rate borrowings is based on TEPPCO’s senior unsecured non-credit enhanced long-term debt rating issued by Standard & Poor’s Rating Services and Moody’s Investors Service, Inc. The Fifth Amendment added a term-out option to the Revolving Credit Facility in which TEPPCO may, on the maturity date, convert the principal balance of all revolving loans then outstanding into a non-revolving one-year term loan. Upon the conversion of the revolving loans to term loans pursuant to the term-out option, the applicable LIBOR spread will increase by 0.125% per year, and if immediately prior to such borrowing the total outstanding revolver borrowings then outstanding exceeds 50% of the total lender commitments, the applicable LIBOR spread with respect to borrowings will increase by an additional 10 basis points.

Prior to the effectiveness of the Fifth Amendment, the Revolving Credit Facility contained financial covenants that required TEPPCO to maintain (i) a ratio of EBITDA to Interest Expense (as defined and calculated in the facility) of at least 3.00 to 1.00 and (ii) a ratio of Consolidated Funded Debt to Pro Forma EBITDA (as defined and calculated in the facility) of less than 4.75 to 1.00 (subject to adjustment for specified acquisitions), in each case with respect to specified twelve month periods. The Fifth Amendment eliminated the interest coverage requirement and provides TEPPCO additional flexibility with respect to its leverage test by increasing the threshold ratio of Consolidated Funded Debt to Pro Forma EBITDA to 5.00 to 1.00 (and, if after giving effect to a permitted acquisition the ratio exceeds 5.00 to 1.00, the threshold ratio will be increased to 5.50 to 1.00 for the fiscal quarter in which the acquisition occurs and the first full fiscal quarter following such acquisition. Other restrictive covenants in the Revolving Credit Facility limit TEPPCO’s ability, and the ability of certain of its subsidiaries, to, among other things, incur certain additional indebtedness, make certain distributions, incur certain liens, engage in specified transactions with affiliates and complete mergers, acquisitions and sales of assets. The credit agreement restricts the amount of outstanding debt of the Jonah joint venture to debt owing to the owners of its partnership interests and other third-party debt in the aggregate principal amount of $50.0 million and allows for the issuance of certain hybrid securities of up to 15% of TEPPCO’s Consolidated Total Capitalization (as defined therein). TEPPCO’s obligations under the Revolving Credit Facility are guaranteed by the Subsidiary Guarantors (defined below). At December 31, 2007, $490.0 million was outstanding under the Revolving Credit Facility at a weighted average interest rate of 5.71%. At December 31, 2007, TEPPCO was in compliance with the covenants of the Revolving Credit Facility.

Revolving Credit Facility

On June 27, 2003, we entered into a $550.0 million unsecured revolving credit facility with a three-year term, including the issuance of letters of credit of up to $20.0 million (“Revolving Credit Facility”).
