4

Compliance Certificate signed by a Responsible Officer of Borrower reporting, and showing in detail the calculation of, the Debt/EBITDA Ratio as of such Fiscal Quarter end (among other items). Subject to any corrections to such Compliance Certificate required by the Administrative Agent based on an audit thereof, the LIBOR Margin, Base Rate Margin, and the Commitment Fee Factor shall be set effective as of the date of the Administrative Agent’s receipt of such Compliance Certificate. In the event the Administrative Agent does not receive such Compliance Certificate on or before the deadline therefor pursuant to Subsection 9.2.2, the LIBOR Margin, Base Rate Margin, and the Commitment Fee Factor shall be set effective as of such deadline at Pricing Tier I until five (5) Banking Days after such Compliance Certificate is received.
