A copy of the Credit Agreement Amendment is filed as Exhibit 10.1 to this Current Report on Form 8-K (this “Current Report”).

The Credit Agreement Amendment amends the Credit Agreement to, among other things, (i) allow the Partnership to make additional investments in joint ventures and subsidiaries that are not guarantors of the Partnership’s obligations under the Amended Credit Agreement, (ii) decrease the minimum consolidated interest coverage ratio (as defined in the Amended Credit Agreement, being generally computed as the ratio of consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges to consolidated interest charges) to 2.25 to 1.0 for the fiscal quarters ending March 31, 2014, June 30, 2014, September 30, 2014 and December 31, 2014, with a minimum ratio of 2.50 to 1.0 for each fiscal quarter ending thereafter, and (iii) increase the maximum permitted consolidated leverage ratio (as defined in the Amended Credit Agreement, being generally computed as the ratio of total funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) to 5.50 to 1.0 for the fiscal quarters ending March 31, 2014, June 30, 2014 and September 30, 2014, with a maximum ratio of 5.25 to 1.0 for each fiscal quarter ending thereafter.

Upon the closing of the Credit Agreement Amendment, the Partnership had $60.0 million of outstanding borrowings and $62.3 million of outstanding letters of credit under the Amended Credit Agreement, leaving the Partnership with approximately $512.7 million available capacity for additional borrowings and letters of credit under the Amended Credit Agreement.  In connection with entering into the Credit Agreement Amendment, the Partnership paid a consent fee to the lenders party thereto.
