             successor by merger to
             SunTrust Bank, South
             Florida, National
             Association

             BNP Paribas                   $15,000,000.00           33 1/3%

            outstanding  exceed  at any  time  the  Maximum  Permitted  Revolver
            Outstanding  Amount.  Within the foregoing  limits,  the Company may
            borrow,  repay  and  reborrow  under  the  terms of this  Agreement;

            Borrowings  outstanding,  all  Borrowings  consisting  of Base  Rate
            Advances shall be considered as one Borrowing.  Borrowings under the
            Commitments  shall  be made  through  simultaneous  Advances  by the
            Lenders,  and the amount of each such  Borrowing  shall be  prorated
            among such Lenders  based on the  percentages  set forth above.  All
            Advances by each Lender  shall be  evidenced  by a single  Revolving
            Note payable to such Lender  substantially  in the form of EXHIBIT A
            attached  hereto.  Each  Revolving  Note  shall  be  dated as of the

            immediately due and payable as provided for herein.  No Lender shall
            have any obligation to advance funds in excess of an amount equal to
            the   percentage   set  forth  opposite  such  Lender's  name  above
            multiplied by the Total Commitments.

            otherwise, the Company shall immediately repay the Swing Line Loans,

            Borrowing,  and unless  expressly  agreed by the Required Lenders in
            writing to the contrary in accordance with SECTION 10.02,  shall not
            be deemed a waiver or modification of any condition to the making of
            any future Borrowing."

            subordination  provisions  contained in the Senior Subordinated Note
            Purchase  Agreement.  The principal of and interest on the Notes and
            all other  Obligations will constitute  "senior debt" as that or any
            similar term is or may be used in any other instrument evidencing or
            applicable to any other Subordinated Debt. The Company  acknowledges
            that the Administrative Agent and each Lender are entering into this
            Agreement  in  reliance  upon the  subordination  provisions  of the
            Subordinated Notes and this SECTION 4.24."

            between  the  consolidated  balance  sheet,  cash  flow and  related
            statements of income and such projections supplied to the Lenders by
