Flexible financial covenants  

The credit agreement also provides for more flexible financial covenants and debt restrictions through the amendment of certain customary covenants, including the modification of the financial covenant that is based on our debt to earnings ratio. The amended debt to earnings ratio of Total Funded Debt to EBITDA, as those terms are defined in the agreement, as of the last day of each fiscal quarter cannot exceed (i) 3.5 to 1.0, if none of the $270 million private placement senior notes due 2013 remain outstanding, or otherwise (ii) the then applicable maximum multiple under the $270 million private placement senior notes due 2013.
