                                                             to Second Amendment
                                                             -------------------


     "Applicable Premium" means, with respect to all Loans, (A) for the period
      ------------------
from the Covenant Effective Date through the date which is three Business Days
after the delivery of the financial reports and certificate delivered to the
Agent pursuant to Section 7.09(a) and 7.09(c), respectively, for the fiscal
                  ---------------     -------
quarter of the Company ending December 29, 2001, 0.50%, and (B) thereafter, the
percentage specified below opposite the Leverage Ratio (which rate shall be
calculated as of the last day of the then most recently ended fiscal quarter of
the Company) calculated for the periods described below:


--------------------------------------------------------------------------------
Leverage Ratio at End of each Fiscal Quarter              Applicable Premium
--------------------------------------------------------------------------------
Greater than or equal to 65.00%                                   0.50%
--------------------------------------------------------------------------------
Less than 65.00%                                                  0.00%
--------------------------------------------------------------------------------

     The Applicable Premium shall be adjusted automatically as to all Loans then
outstanding (without regard to the timing of Interest Periods) three Business
Days after the delivery to the Agent of the financial reports and certificate
delivered pursuant to Section 7.09(a) and Section 7.09(c), respectively, for the
                      ---------------     ---------------
fiscal quarter of the Company ending December 29, 2001, and three Business Days
after delivery to the Agent of such financial reports and certificate for each
fiscal quarter of the Company thereafter.  If the Company fails to deliver such
financial reports and certificate to the Agent for any such fiscal quarter by
the date required hereunder, then the Applicable Premium for all Loans beginning
three Business Days after such date shall, until three Business Days after
delivery of such financial reports and certificate, be the next highest
Applicable Premium as set forth in the chart above immediately above the
previously effective Applicable Premium; thus, for example, if the Applicable
Premium had previously been 0.00%, a failure to deliver such financial reports
and certificate on a timely basis would cause the Applicable Premium to be 0.50%
until three Business Days after such delivery.
