                  the Eurodollar Rate applicable to Eurodollar Rate Loans
                  outstanding during any fiscal quarter of the Borrowers (the
                  "Applicable Quarter") (a) if the ratio of (i) the Consolidated
                  Total Debt of the Borrowers and their Subsidiaries to (ii) the
                  Consolidated EBITDA of the Borrowers and their Subsidiaries
                  determined as of the last day of the fiscal quarter of the
                  Borrowers (the "Determinative Quarter") immediately preceding
                  the Applicable Quarter (hereinafter, the "Relevant Ratio") is
                  equal to or greater than 3.75 to 1.00, one and three-quarters
                  of one percent (1 and 3/4 of 1%), (b) if the Relevant Ratio is
                  equal to or greater than 2.50 to 1.00 but less than 3.75 to
                  1.00, one and one-half of one percent (1 and 1/2 of 1%), (c)
                  if the Relevant Ratio is equal to or greater than 2.00 to 1.00
                  but less than 2.50 to 1.00, one and one-quarter of one percent
                  (1 and 1/4 of 1%), (d) if the Relevant Ratio is equal to or
                  greater than 1.50 to 1.00 but less than 2.00 to 1.00, one
                  percent (1%), and (e) if the Relevant Ratio is less than 1.50
                  to 1.00, three-quarters of one percent (3/4 of 1%); provided,
                  however, that if the Consolidated Tangible Net Worth of the
                  Borrowers and their Subsidiaries as of the end of the
                  Determinative Quarter is less than $14,000,000, each of the
                  various levels of the Applicable Margin as provided above will
