Covenant terms as of the end of each rolling period, which consists of any period of four consecutive fiscal quarters, a consolidated debt coverage ratio (consolidated indebtedness to consolidated EBITDA, as defined in the 2012 Revolving Credit Agreement) not to exceed 5.00-to-1.00; provided, for the rolling period ending June 30th of each year, the maximum consolidated debt coverage ratio will increase to 5.50-to-1.00.

Covenant terms permit unlimited investments in joint ventures and unconsolidated subsidiaries, provided that no default exists, and to limit the amount of cash distributions for such joint ventures and unconsolidated subsidiaries included in the calculation of the consolidated debt coverage ratio to 20% of consolidated EBITDA (the Amendment). In addition, the Amendment provides that we will be in compliance with the consolidated debt coverage ratio as long as it does not exceed 6.50-to-1.00 for the rolling period ended June 30, 2012 or 6.00-to-1.00 for the rolling period ending September 30, 2012. The Amendment further stipulates that if the Asphalt Operations were owned by an unconsolidated joint venture, the maximum allowed consolidated debt coverage would revert to 5.00-to-1.00. Therefore, as of September 30, 2012, our consolidated debt coverage ratio could not exceed 5.00-to-1.00.
