Revolving Credit Facility

We have a $100 million revolving credit facility (the “Facility”), which may be increased to $150 million based on the terms and subject to the conditions set forth in the agreement relating to the Facility (the “Credit Agreement”). The Facility matures on September 15, 2015.  The Facility contains both affirmative and negative covenants, which we believe are customary for arrangements of this nature.  At September 30, 2013, we were in compliance with all financial covenants under the Credit Agreement and had not drawn on the Facility.
